Patent GB-864626-A (GB)
Title: Torque transmitting or generating apparatus
IPC: B60L50/30
Filed: 1957-08-06
Abstract: 864,626. Transmitting mechanical power. BLISS CO., E. W. Aug. 6, 1957 [Aug. 30, 1956], No. 24715/57. Addition to 807,654. Class 38 (4). In a flywheel and electromagnetic clutch unit as described in the parent Specification the functions of the A.C. and D.C. are reversed so that the A.C. gives a reverse accelerating torque and the D.C. gives a decelerating torque. In addition the unit can be arranged to give both directions of rotation to the output shaft by reversing the order of application of the A.C. and D.C. to the windings. The Specification also describes a programme control system giving two directions of rotation. When the flywheel is started from rest, a starting signal over a line 262 energizes an accelerating relay 264 applying A.C. to the induction windings, the signal also de-energizing a clutching relay 266 and energizing a brake relay 268 which holds the driven member stationary through a holding means 207. At a given speed a speed-sensitive means 230 de-energizes relay 264 and the flywheel coasts. A programme means 240 bypasses means 230 through relay 274 which energizes the D.C. windings and the brake relay 268 is released, thus the output shaft rotates negatively until a retarding torque trip 244, which may be a limit switch, de-energizes relay 274, and actuates clutching relay 266 which slows down the output shaft. At zero speed, or at some determined machine position, relay 266 is released and brake relay 268 energized. A selector switch 254, and associated switches 256, 258 and 260 may be thrown to the other positive output torque position, rendering positive output torque programme means 276 effective. A signal from means 276 over line 284 releases acceleration relay 280 and brake relay 282 also actuates clutch relay 286 thus decelerating the flywheel and accelerating the output shaft. A retarding torque trip 288 also acts similarly to trip 244 releasing clutch relay 286 and energizing relay 280. After the output shaft has come to rest or at some other determined position the holding means 207 is energized through a relay 282. The flywheel member may be additionally driven by an electric motor. The clutching action may be performed by a separate D.C. winding separately energized or this winding may be energized in combination with the induction windings. The flywheel and driven members may be concentric or in parallel planes. Specification 864,627 is referred to.

Title: Improvements in or relating to the blending of extrudable thermoplastic material with modifying agents
IPC: B29C48/395
Filed: 1950-10-10
Abstract: <PICT:0674716/IV (a)/1> Powdered thermoplastic material, e.g. polystyrene, from a hopper 1 is mixed in a blender 3 with a modifier, e.g. a filler, dye, or pigment such as titanium dioxide, from a hopper 2 to provide a mixture having a much higher concentration of modifier than is desired in the final product.  This powdered concentrate may, as an intermediate step, be extruded in strip form and cut into pellets of uniform size which are then tumbled together. The concentrate is fed from a vibrative feeder 4 on to a conveyer 5 having an automatic weighing control 6 which ensures a constant rate of discharge into a constant-speed extruder 7.  The extruder 7 may be fed with a number of different concentrates from several conveyers 6. It is operated in a "starved" condition and discharges molten concentrate at the same constant rate at which it is fed into a variable-speed extruder 8 having a mixing head 9. The concentrate is here diluted with molten thermoplastic fed under constant pressure from a source 10, the final blend being extruded in a thin strip which is cut into pieces by a cutter 11. To ensure a constant rate of discharge of the plastic from the extruder 8, the emergent strip is passed between the plates of a condenser 12 having a H.F. potential across it.  Change in the thickness of the strip alters the capacitance of the condenser and such change is immediately compensated by automatic actuation of a motor driven rheostat 13 in the circuit of the variable-speed motor 14.  The desired ratio of modifier in the final product is obtained by adjusting the rate of extrusion of the large extruder 8.

Title: An apparatus for forming a sand mold
IPC: B22D13/10
Filed: 1958-08-01
Abstract: 889,241. Moulding- and casting-machines. WOODWARD IRON CO. Aug. 1, 1958 [Nov. 12, 1957], No. 24835/58. Class 83 (1). Means for forming a pipe mould in a hollow cylindrical flask 16 comprises means for blowing sand between the flask and a coaxial mandrel therein, means for allowing escape of the air while retaining the sand, and a pattern and a piston movable longitudinally of the mould to compact a shoulder on the mould. The moulding- machine 10, and a blowing-machine 11 are combined with a casting-machine 12, an ejecting machine 13 and tracks 14, connected by fluid-pressure-operated elevators 17 for moving the flasks in an automatic cycle. The flasks carry twin tyres to engage the track. A sand-blower 55 having a hopper 59 and sand-box 58 is mounted for reciprocation. A blow-box 62 can be moved beneath the sand-box 58 and a rubber-faced table 66 is then raised to seal the boxes. The box 62 contains a perforated tube 68 to agitate the sand, and carries at its forward end a flask-closing assembly over which slides the hollow mandrel 77 which is advanced by a fluid pressure device 81. Air is exhausted through vents in the flask or in the mandrel. In order to compact a shoulder on the end of a mould, the forming member 128 at the blowing end is made of two relatively sliding parts 128, 139. After blowing is complete, air in a cylinder 140 forces the part 139 forwardly to follow the mandrel as it is withdrawn. The leading end 147 of the member 139 thus compresses the shoulder. In a modification, the shoulder-compressing portion 161, Fig. 4, is formed on an elongated piston 165. As the mould passes along the track 14, end cores are fitted.

Title: Improvements in or relating to thermionic valve circuits
IPC: H04N5/08
Filed: 1951-10-25
Abstract: 711,072. Television. GENERAL ELECTRIC CO., Ltd., and GRIFFITH, G. W. S. Sept. 19, 1952 [Oct. 25, 1951, No. 25003/51. Class 40 (3). [Also in Group XL(c)] A circuit for amplifying television or like signals, i.e. signals comprising rectangular pulses of one polarity with respect to a datum level and further components of opposite polarity, incorporates a single pentode 1 and is arranged to provide two outputs, one from across cathode load 5, 6 and corresponding to the whole of the input signal and the other from across anode load 7 and corresponding to the rectangular pulses. The input signal is applied at terminals 2 with the rectangular pulses in a negative-going direction, and the effective suppressor grid bias due to the drop across resistors 3, 4 and 5 is selected so that the anode current is cut off for input signals positive in excess of the datum level. Accordingly anode current is allowed to flow only during the rectangular pulses to produce a corresponding output voltage across resistor 7. In the case of a pentode having a short suppressor grid base, the suppressor grid may be returned to a voltage positive with respect to earth obtained from a potentiometer connected across voltage source 8. Also the screen decoupling condenser 10 may be returned to cathode and resistor 4 omitted. Suitable component values are given for the circuit shown.

Title: Improvements in or relating to liquid level control devices
IPC: G01F23/24
Filed: 1958-08-05
Abstract: 844,010. Regulating liquid levels. MOELLER, C. Aug. 5, 1958. No. 25081/58. Class 123(1) [Also in Group VIII]. A liquid level regulator, e.g. for a washing machine 1, comprises a U-gauge in the form of a block 10 of thermoplastic material with a vertical channel 9 the lower end of which communicates, through a restriction 13, with a transverse channel 12 opening into the lower ends of vertical channels 14-17 having adjustable contact rods 18-21 respectively. The upper ends of the channel 9 and a vertical tube 4 are interconnected by a narrow tube 8, and the lower ends of the tube 4 and the machine communicate with each other through a tube 3. A vertically adjustable tube 7 screwed into an opening in the top 6 of the tube 4 ensures, when the machine is empty, that the tube 9 is open to the atmosphere through the tubes 8, 4, 7. During filling, water rises in the tube 4 and, upon reaching the level of the lower end of the tube 7, prevents the escape of air from the latter, the liquid, e.g. mercury 22, in the tube 9 being proportionally compressed and that in the tubes 14-17 rising correspondingly to engage one or more of the contact rods 18-21. Electrical circuits are completed between the rods 18-21 and a wire 25, extending through a plug 11 which closes one end of the channel 12, to control e.g. the liquid level of the container and to initiate washing operations or timing mechanism.

[Classes 80 (i) and 80 (ii) ] In marine reversing gearing of the planetary type suitable for use with internal-combustion engines, the crank shaft 14, Fig. 1, is connected by a flexible diaphragm 13 to the driving casing 12 of a fluid coupling 10. The coupling turbine 15 is fixed to a shaft 16 journalled at 17 in the casing 12 which is located by a part-spherical spigot 18. The shaft 16 is splined at 20 to a shaft 21 journalled in a double-row roller bearing 22 in a fixed housing 23 and capable of resisting both journal and thrust loads. The impeller 11 is supported by a ball bearing 24 and the fluid coupling is sealed by a gland 25 which may comprise a cup 26 of synthetic rubber. A reservoir chamber 27 may be formed between the casing 12 and turbine 15 and communicate with the working circuit by ducts 28. The shaft 21 is connected to a plant carrier comprising shells 30, 32, the latter being supported by a ball bearing 33 in a second fixed support 35. An output shaft 37 carries a fast sun wheel 42. A sun-wheel 43, journalled on the shaft 37, is integral with a sleeve 45 on which is a forward-drive brake drum 46, a ball bearing 47 serving to take journal and thrust loads. A sun-wheel 48 is journalled in the hub of the shell 32 and is integral with a sleeve 50 carrying a reverse-drive brake drum 51, the bearing 49 taking only journal loads, and the bearing 52 both journal and thrust loads. The planet carrier encloses three similar uniformly spaced planet sets comprising wheels 53, 54 and 55 of which 55 is rigidly clamped between 53 and 54 by screws 56. This planet set is mounted on a deep groove ball bearing 57 to take journal and thrust loads and a roller bearing 58, these bearings being mounted respectively on eccentric flanged pins 59, 60 which may be adjusted to obtain equal distribution of load. The wheels are helical, the helix directions of the teeth of the various wheels being so selected that the thrust on the propeller shaft is opposed by the thrust of the teeth on the intermediate sunwheel, and the thrusts in the two planet wheels of each set that are loaded oppose each other on both the forward and reverse drives. The control mechanism, Fig. 3, includes brake bands 64, 65 adapted to be actuated by cams 71, 72 through levers 73, 74 and rods 66, 67. The lever 68 actuating the cams may be moved to position I where the drum 46 is free and drum 51 is arrested to give a backward drive to shaft 37; to position II where drum 51 is free and 46 is arrested to give a forward drive to shaft 37; to the position shown whereby both brakes are applied and the hydraulic coupling permits the engine to run with the propeller stopped. At 180 degrees from the position shown, both brakes are released. The Specification contains an explanation as to how the various thrusts are taken.
