This is a 1950 2-71 GM Detroit diesel. It is mine (Rick Delair here). I lost prime on the fuel. Needs a better check valve in the fuel line. She always starts instantly if fuel is up, and is in EXCELLENT condition mechanically snd is a sweetheart! It has a Twin-Disk snap over clutch and a 1925 Studebaker pickup truck radiator to make it into a stationary power unit at a windmill in Vermont. I bought it for 200 bucks in 2003 at the Dublin,NH old engine show and swap meet and had to replace the blower because it got rain water in it in outdoor storage that froze and broke the lower blower rotor, locking it and the engine up. I got a good used blower from an outfit in California and also my rare 4-51 valveless Detroit from the same seller. He sold me tge blower for 250 bucks and the 4-51 engine for 400! I had the 2-71 running in 2 days and the 4-51 running in a few months, as I had to pull the gummed up injectors out and soak them in solvent to free them up. Had it running the next day after freeing them! The 4-51 loop charged (like a gasoline 2 stroke) valveless is insanely rare, and the 2 cylinder 2-51 version even more rare than the 4 cylinder! I am hoping to bring my 2-72 to the fair again this year! 😋
The bare solid copper conductor was generally used in medium voltage branch circuits for smaller streets, generally no more than 8,6 or 4 AWG, over time they were replaced by ACSR 1/0 or 4 AWG,normally capacity did not exceed 1000-2500kVA at 13.8kV. While 4/0 AWG and 336.4 ACSRs have always been used on trunk feeders, typically 13.8kV will flow 5000 to 8000kVA rated capacity, or 6250 (4/0 AWG) to 12,000kVA (336.4kcmil) permissible limit. I've heard that 477kcmil is also used in trunks I'm making a reference here in Brazil, but it shouldn't deviate too much from the North American 12.470 volt specifications.
I would like to start a Wax Cylinder Company which would Record Income streams so I would like to ask the wax Candles making companies to set up a Partition in the Middle of the Storage Glass of the Wax Candles and use three wicks in the wax candles for the purpose of mining of wax cylinders
This video triggered a lot of memories and nostalgia. I was a EE undergraduate at Syracuse University from 1964 through 1968. The EE Department had an analog GE network analyzer that filled a very large glass walled room directly inside the entrance to the engineering building. If I remember correctly, it was mostly used to analyze large transmission networks for Niagara Mohawk. I understood GE Schenectady also had one or two of these huge analyzers. At this moment, I have in my hand, GE publication GET-1285A, titled "G-E Network Analyzers", Copyright 1950, Price $5.00. The pictures trigger a lot of memories. The laboratory used undergraduate students to help set-up the machine for a particular study and then help laboriously record the data for each of many points and conditions. The actual numerical data was read off an optical meter with very high resolution (swinging mirror/reticle over relatively long-distance optical path). A very large one-line drawing of the network was open and secured to a glass tabletop with a relatively fine matrix of small indicating lights. A data point was selected, and its numerical value read out loud by the first operator. A light lit under the appropriate network component on the one line and then the data was hand written on the drawing by the second operator. It was a time-consuming effort just to collect the data to say nothing of setting up the network or even changing it to simulate another of the many configurations being tested. I would schedule time between classes to work at the analyzer and, at first, was paid minimum wage 0f $1.00/Hour. Before graduating I think I was getting $1.50/Hour. Each week I received a check for $10 to $12 and that represented the same amount my dad had allocated for me in my checking account for spending money so I was able to double my beer, girls, etc. funding. There is about an 11:1 inflation ratio between then and now so I remember feeling flush with "off my dad's books" spending money. In the summer of 1966, I worked as a student engineer for an electric utility in their System Planning Department. One of my jobs was to run a digital load flow study. It used a GE time sharing system about 70 miles away and I accessed it through a model 33 Teletype and telephone modem. The program was written in Basic and was named "ChiFlow" because it was written by the University of Chicago (I think). I do not at all remember if it was as in depth as the analog GE Network Analyzer, but it was regularly used, and each study took many "thinking" hours before the analyzed data starting printing on the TTY. I don't know if anyone is even going to read this as this is a relatively old video but I, nevertheless, have enjoyed reminiscing.
This doesn't really explain how sound is played off an inanimate object. That's the "voodoo" at play. Also, how much of this did Edison invent and how much did he "just" piece together various products to create something new?
For somebody to come up with the math and the engineering of such device is just astounding! Got a lot more respect for the fluorescent now in the era of leds 😁 great video btw thanks for sharing
It is misleading to call the gyro/engine vanes - guidance - it is stabilization. The V2 was a ballistic missile; it had no "guidance" Guidance is directing a missile to a target. The only Guidance the V2 had was the lunch platform that gave it a general direction. If it was accidentally launched toward the northsea there was nothing in the V2 which would direct it to redirect it's course towards London or Amsterdam; let alone a ship at sea. Because the V2 had no "guidance" it was very inaccurate, much like a big artillery shell. The Germans did deveope some missiles with Guidance but the V2 isn't one of them.
The triode was the first non-mechanical device to provide power gain at audio and radio frequencies, and made radio practical. Triodes are used for amplifiers and oscillators. Many types are used only at low to moderate frequency and power levels. Large water-cooled triodes may be used as the final amplifier in radio transmitters, with ratings of thousands of watts. Specialized types of triode ("lighthouse" tubes, with low capacitance between elements) provide useful gain at microwave frequencies.
"I once started at a low pressure sodium lamp for three hours." ... Even a regular lamp will do that to your eyes, if you stare at it for three hours, bro.
Gas was a better solution back then and still is today. Electric will not take over until we have a power supply solution. Battery technology is not good enough yet. You want an electric car then go buy it. Don't rely on my tax dollars to subsidize your purchase. Don't force me to buy one.
PS: Nikola Tesla (a freak 😊), ...he studied a lot and liked to study - an excellent theoretician, our man - a Slav 😊. Unfortunately, nothing, nothing!!! specifically (apart from his - Tesla 😊 coil - more a toy than ... necessary use) commercial usable HE DID NOT INVENT !!! 😊. Too bad 😊. He could rather devote himself to the radio, and not to the unrealistic transmission of energy through the ether 😊. All other things are rather partially his phantasmagoria and mainly the invention of journalists 😊. Journalists, especially in America (USA), like to bend the truth according to what and when it suits them 😊. They only recognized the patent for the radio after his death 😊, they didn't want to pay anyone, not even Markoni. ...
I didnt even know the history of electric cars. Thats amazing that we had electric cars 120 years ago. I just found this history out listening to someone on the radio. And I said did I hear this person correctly? They had electric cars back then? And they certainly did. And the same problem exists today as to why the electric cars are not practical. Not enough charging stations and the cars cant be used for long distances!!!
Erratum: The armature is that winding of an electrical machine in which alternating current flows. At 0:15, the rotor is erroneously captioned as the "armature" of a separately-excited, rotating-field synchronous machine. The stator windings are in fact the armature on that machine (AC), whereas the rotor windings comprise the field (DC). It is a rotating-field machine, not a rotating-armature machine.
It would have been better if all this was shown with a little slow motion. You have to read and see that freaking electrons moving so fast. Why can not this all be shown slow for understanding.
