Title: An Improved Method of and Means for Varying the Resistance of an Electric Circuit.
IPC: H02P25/26
Filed: 1916-06-23
Abstract: 103,254. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). June 23, 1916. Systems for alternating - current, motors only; controllers with combinations of resistances.-Sets of resistances are arranged in parallel, and regulation is effected by cutting out steps shifting from one resistance to another in excluding successive steps. The connexions are shown for controlling a slip-ring induction motor. The resistances R<1>, R<3>, R<5> are in parallel with the resistances R<2>, R<4>, R<6>, and, during starting, the switch S<1> closes to shortcircuit the step R<1>, then the switch S<2> shortcircuits the step R<2>, End so on, until the last switch short-circuits all the resistance. The switches are interlocked so that they can only be operated in proper sequence. The resistance steps are proportioned to minimize the unbalancing of the currents in the different branches.

Title: Improvements in the treatment of condensed or evaporated milk
IPC: A23L3/06
Filed: 1926-04-06
Abstract: 268,138. Vidal, A. E., (Anderson-Barngrover Manufacturing Co.). April 6, 1926. Testing efficiency of cans. -Condenser or evaporated milk in hermetically sealed cans is sterilized &c. by passing the cans in a continuous stream first through a zone in which their temperature is raised to a point below that required for sterilization, then automatically separating the leaky cans from the tight ones, introducing the stream of tight cans to a zone in which they are subjected to sterilizing temperature, and then passing the stream through a cooling zone at a pressure above atmospheric. This may be followed by an automatic separation of tight cans from those which have developed leaks. As shown in Fig. 1, the cans enter the preheater A by a shoot 1 and pass on through a leak detector B to a sterilizer C, cooler D, and second leak detector E. In separating the tight from the leaky cans use is made of the end bulges on the tight cans 30<1> in the detector B and of the end bulges on the leaky cans 30<11> in the detector E, the stream of cans 30 being led between rotating spaced discs 28, Fig. 4, which are flared or divergent towards their peripheries as at 29. Fig. 4 shows a section of the detector B. The detector E is similar, but the leaky cans 30<11> then have bulged ends and consequently are supported by the flared parts 29 of the discs.

An emergency condenser installation for a liquid cooled nuclear reactor has, in addition to an emergency condenser, a steam collecting vessel dimensioned to receive the whole of the steam generated in the reactor in the period between the interruption of the discharge of steam to the turbine condenser and the bringing into service of the emergency condenser. This steam collecting vessel is a pressure vessel partially filled with cold water with atmospheric air above the water and nozzles to introduce the steam being provided in the vessel. If the discharge of steam from the superheater reactor 4 is shut off, then the connection to the steam collecting vessel 9 is established very quickly, but too much steam must be prevented from entering the vessel otherwise sudden cooling of the reactors 1 and 4 would ensue. Also when the emergency condenser 12 is able to operate the supply to the vessel 9 must cease and the steam directed to the condenser 12. Should the steam from reactor 1 to superheater 4 be interrupted then the connection between the reactor 1 and condenser 12 must be established very quickly, and the vessel 9 must be shut off.
