This little device, the work of the Bijur Motor Appliance Company of Hoboken, N. J., consists of a small 12-volt electric motor operated by a storage battery connected through a geared reduction to a Bijur automatic screw drive. On the end of the screw shaft is cut an 8-tooth pinion which meshes with a larger gear on the propellor shaft. The starter will turn over the engine at 40 to 50 r.p.m. with a consumption of 100 to 110 amperes and a maximum of 1300 foot-pounds is available on the engine crank shaft, for breaking loose...
...place in a few weeks. The building contains 25 rooms, for research and instruction work. Five of these rooms are under ground, and will be used as constant temperature rooms. One of these, about 32 by 44 feet area, is to contain a storage battery of 100,000 volts. This storage battery, which will be the highest voltage storage battery in the world, involves many new problems in its insulation and switching devices, but considerable aid in solving them has been derived from the previous experience of Professor Trowbridge in his work with the 40,000 volt storage battery...
Each room of the new laboratory is provided with equipment for turning it into a dark room for photographic purposes, and all are provided with water and gas, and a distributing board for electric currents. The currents available in each room at the outset will consist of 110 volts direct current, 110 volts 60 cycle alternating current, 220 volts 500 cycle alternating current, 500 volts direct current, and a storage battery voltage from 2 to 80 volts, in two volt steps. Ten of the rooms are also provided with insulated bushings through the floors, in such...
...building will be equipped with all the latest high tension and high frequency electrical apparatus, including two 500,000 volt transformers. These are of the largest type of transformers made. There will also be a 60,000 volt storage battery...
...Rhodes first discussed the alternating current feeder system and gave an account of the troubles that had been experienced in making the first underground cables for an 11,000 volt system. He classified the causes for the burnouts into two groups: the first containing inherent faults in the cables, and the second accidental injuries to the cables. Under the latter head he mentioned the process of electrolysis...
