Title: Improvements relating to measuring and segregating apparatus
IPC: B26D7/30
Filed: 1960-09-12
Abstract: 945,260. Slicing machines. CASHIN Inc. Sept. 12, 1960 [Sept. 10, 1959], No. 31372/60. Heading A4C. When a predetermined weight of food slices has been deposited on a weighing conveyer belt 31 electrical mechanism inside a cabinet 30 stops the food pusher 15 which after a timepause restarts the feed, the control including a device which on rotation of the eccentric disc blade 16 electro-magnetically (352) induces signals which ensure that the pusher restarts only when the blade is in position ready to cut the next slice. The pusher 15 is actuated by a piston inside a hydraulic cylinder 24 supplied with fluid by control valves. A power supplier and oscillator circuit 394 energizes the primaries of differential transformers 432, 434. The slice weight displaces the core of transformer 432 which signal is stepped up by transformer 450 and then amplified by a twostage amplifier tube circuit 460 which energizes a relay 392 so that the solenoid stop valve is actuated to stop the feed. Energization of relay 392 permits another relay 330 to be energized to energize a head lift solenoid 512 which shifts a bell crank to elevate the conveyer 31. This starts the timing action to determine t h e space between the sliced batches, and upon actuation of the synchronizing means (Fig. 4 not shown) a thyatron tube 338 will conduct and energize a relay 360 to energize the start coil of the double solenoid valve 220. The permanent magnet 366 on rotation of the knife shaft induces coil 380 to deliver a negative pulse at the base of transistor to trigger the electronic network to restart the feed pusher 15. Specification 853,760 and U.S.A. Specifications 2,812,792, 2,870,810 and 2,903,032 are referred to.
Patent GB-881913-A (GB)
Title: Improvements in or relating to control systems for electric motors operating double skip hoists
Inventor: HOLMES FRANK RICHMOND
IPC: B66B1/48
Filed: 1958-10-02
Abstract: 881,913. Control of two D.C. motors. POWER-GAS CORPORATION Ltd. Sept. 25, 1959 [Oct. 2, 1958], No. 31430/58. Class 38 (3). First and second D.C. motors operating a double skip hoist have their armatures AA, AB connectable in parallel, the respective armature currents being measured across series resistors R7, R8, connected to control windings 41, 43 of magnetic amplifier 42. The output of the amplifier is applied through rectifier 46 to the shunt field winding BPF of the second motor. Appropriate operating conditions are established by means of bias winding 44 on the amplifier, and by adjusting resistor 45 in series with the shunt field winding APF of the first motor. If, during subsequent operation, the first motor takes a heavier load, the voltage applied to winding 41 exceeds that applied to winding 43 and the output of the magnetic amplifier decreases to weaken the field winding BPF. This causes the second motor to consume a larger armature current and take a larger share of the load. Conversely, if the second motor draws a larger armature current, the output of the magnetic amplifier increases to strengthen the shunt field of the second motor and thereby reduce its armature current. The magnetic amplifier may be operated either about the centre of the straight part of its characteristic curve, or near the bottom end thereof. The single-stage magnetic amplifier shown may be replaced by a two-stage amplifier comprising two magnetic amplifiers in series, Fig. 5 (not shown). The parallel-connected shunt field windings may be controlled by resistors in series therewith, Fig. 2 (not shown). In another arrangement, however, the shunt field excitation is controlled entirely by magnetic amplifiers with means for preventing the motor armature currents from exceeding a predetermined maximum value Fig. 6 (not shown). The two motors are mechanically coupled to a common winding drum and are controlled by a plurality of switches actuated by non-rotatable nuts on screw shafts driven from the drum. Seriesparallel control is afforded, with bridge transition, the motors having series field windings which are not in circuit when the armatures are connected in series but are brought into circuit at the transition stage and are in circuit when the armatures are connected in parallel. Brake release magnets are provided with economy resistors, Figs. 1-3 (not shown). Diverter resistors are connected in parallel with the armatures to provide crawling speed.

Title: Improvements in and relating to elastic fluid power plants
IPC: F01K9/04
Filed: 1939-12-08
Abstract: 533,882. Controlling steam generation. BRITISH THOMSON - HOUSTON CO., Ltd. Dec. 8, 1939, No. 31827. Convention date, Dec. 8, 1938. [Class 51 (i)] [Also in Group XXVI] Boiler feed, fuel and air pumps 18, 21, 22 are driven by an auxiliary turbine 12 in front of the main turbine 13. The inlet valves 23 of the turbine 12 are controlled only by a pressureresponsive device 30 so as to maintain the pressure before the valves constant. The inlet valve 34 of the main turbine 13 is controlled by a device 37 manually or automatically adjusted in accordance with the speed or load of the turbine 13 and by a device 38 responsive to over-speed of the turbine 12. A byepass valve 41 is opened when the valve 34 shuts. If the load on turbine 13 increases, the valve 34 is opened wider. This causes an immediate reduction in the back pressure of turbine 12 and a consequent increase in the speed of that turbine and the pumps. The subsequent rise in the pressure at 31 brings about a further opening of the valves 23. The byepass valve 41 may be separately operated by a rise in the pressure in the pipe 40 in front of it. The devices 37, 38 may act upon separate valves in series. Regulation is also effected by the water-level device 60 in the steam generator 10, in conjuction with a throttle 65 in the air supply and flow responsive devices 67, 68 in the fuel and air lines which control a fuel valve 87. If the waterlevel falls, the supply of both air and fuel is immediately decreased and, due to a fall in the steam pressure of the generator, the valves 23 will be closed slightly. Since the load on the turbine 13 is unchanged, its speed will fall and the valve 34 be opened further. The turbine 12 will then speed up owing to the reduced backpressure and the boiler feed will be correspondingly increased. A pressure relief byeppass 90 is provided for the fuel pump.
