Filed: 1939-05-26
Abstract: 532,108. Hydraulic telemotor devices. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S. I. A. M. May 26, 1939, No. 15668. Convention date, June 10, 1938. Addition to 509,350. [Class 69 (ii)] The hydraulic tele-control device described in the parent Specification is modified so that a receiving station R can be operated from either of two or more transmitting stations Ta, Tb without the action of the operative transmitter affecting the idler ones. The devices R, Ta. Tb are connected in parallel to the pipe lines Y, Z, and valve boxes t are provided in connection with the pipe lines 1, 2; 3, 4 leading from the transmitters. Each box t contains a pair of valves q, s and on operating, say, a transmitting arm La the pressure produced in the outlet pipe 2 opens the valve q in the adjoining box directly by fluid pressure, and causes a piston p to open the valve s. The receiver R is thus operated so that the arm L repeats the motion of La, but the variation in pressure in the pipes Y, Z, causes the valves q, s associated with the other transmitting station to close, so that the transmitting device Tb is unaffected by operation of the one Ta.

Title: Improvements in an automobile generator regulator
IPC: H02J7/14
Filed: 1932-06-04
Abstract: 386,863. Charging batteries. FORD MOTOR CO., Ltd., 88, Regent Street, London. June 4, 1932, No. 15749. Convention date, July 31, 1931. [Class 38 (iv).] A charging system for motor-vehicle batteries in which a regulator provides for a low rate of charge only when the generator voltage is equal to the-battery voltage when fully charged, and for a high rate of charging only after the speed of the generator has been reduced below its normal operating speed, has normally responsive means varying the action of the regulator to compensate its operation for the varying fully charged battery voltages at different temperatures. The regulator 27 is responsive to the voltage of the generator 13 and operates to'insert and retain a resistance 32 in the fold circuit when the voltage has risen, the battery being in parallel with the generator through the closed cut-out 23, to a maximum value dependent on the temperature. This is effected by mounting the stationary contact of the regulator on a bimetallic element 29 so that in summer, for example, the air gap between the armature and core will be reduced to cause the regulator to operate to reduce the charging rate at a lower maximum voltage. The regulator and cut-out are of similar construction and, with the resistance, are mounted in a single container which may be secured upon the top of the generator and in the blast of the fan.

Title: Improvements in or relating to crystal growing apparatus
IPC: C30B7/00
Filed: 1951-07-04
Abstract: <PICT:0713656/III/1> In crystallizing apparatus of the kind in which solution is circulated between a growing tank and dissolving tank, the solution is returned to the growing tank through a tubular device 1, 3 supported at an intermediate point on the cover 21 of the growing vessel by a flange 10, the lower part 1 of the device being surrounded by a jacket 14 projecting below the open end B of the lower part.  The jacket 14 projects into the solution 23 in the tank and the end B of the part 1 terminates above the level 24 of the solution in the jacket 14, depressed relative to the level of the main body of solution.  The tubular device and jacket are constructed from poor conductors of heat, e.g. polymethylmethacrylate or glass, to minimise heat transfer from the warmer returning solution to the solution outside the walls of the jacket 14.  Evaporation from the body of solution by heat transfer from the returning solution is largely confined to the surface 24 within the jacket 24 and is thus restricted to that required to saturate the vapour space within the jacket. Crystallization and spurious seeding around the point of entry of the returning solution is thereby largely prevented.  The returning solution enters the part 3 by a side tube 7.  The part 3 also carries a thermometer 26.  Specifications 707,976, 707,977 and 707,978 are referred to.
