Abstract: 181,712. Akt.-Ges. Brown, Boveri, et Cie. June 14, 1921, [Convention date]. Pneumatic conveyers and elevators.-In a pneumatic conveying system means is provided for separately and automatically throttling or closing any suction pipe as soon as it commences to suck idly. The throttle h, Fig. 2, tends to be closed by a spring k acting on the arm i, but is held open by the engagement of a pawl l with a hooked stop m rigidly connected to a diaphragm o which is subjected to the pressure existing in the pipe at the point C. When the pipe sucks idly, the spring r moves the diaphragm to the right and releases the pawl l, so throttling or closing the pipe. The throttle is restored to open position by hand by means of the chain t. In a modification, Fig. 3, the throttle is actuated by a piston 3 working in a cylinder u, the slide valve v of which is connected to a diaphragm w acted on by a spring z and exposed to the pressures on opposite sides of the throttle. In a further modification, Fig. 4, a closing device 4 is maintained by gravity in its lower position during normal working, but rises as soon as the material conveyed falls back. If the throttling devices shown in Figs. 3 and 4 do not tightly fit the pipe, they will re-open automatically as soon as the inlet of the pipe is immersed in the material.

Abstract: 1,044,727. Checking receipts. MAGNAFONE RECORDER CO. Ltd., and J. SMITH. Jan. 21, 1965 [April 23, 1964], No. 16824/64. Heading G4T. In a combination of a camera and cash register (e.g. for photographing an issued betting slip after each receipt of cash), operation of the cash register renders it inoperable until after operation of the camera. In a first embodiment, actuation of the camera 10 through a switch 61 energizes a solenoid 66 to close a switch RL1A for energizing a second solenoid 71 which is latched RL2A and closes a switch RL2B which permits operation of the cash register 11 on closure of a switch 86. Operation of the cash register 11 energizes a solenoid 92 which opens a switch RL3A to de-energize solenoid 71 but closes a switch RL3B to permit continued operation of the cash register 11 after the switch RL2B has opened. During this normal operation of the cash register 11 a lamp 106 is illuminated but by opposite movement of a switch 100 the cash register 11 may be operated without previous operation of the camera 10 and the lamp 106 is extinguished. In a second embodiment the movable contact 13 (Fig. 2, not shown), is biased to permit actuation of the cash register 10 which, when operated, energizes a relay 30 which is latched 34 and closes contacts 32 to operate a relay 49 switching the contact 13 to permit operation of the camera 11 on closure of a switch 24 and prevent subsequent operation of the cash register 10. Operation of the camera 11 energizes a relay 38 to open contacts 40, thus de-energizing the relays 49 and 30 and returning the circuit to its initial condition.

Abstract: 851,992. Garment finishing apparatus. LEEDS CHEMICAL CLEANING WORKS Ltd. May 27, 1957 [June 1, 1956], No. 17013/56. Class 34(1) A garment, e.g. a pair of trousers, is finished by forcing successive streams of steam and air therethrough whilst suspended from a machine 1, Fig. 1, such that the waist part is firmly held over a fixed cylindrical former 4 and a movable partcylindrical plate 24 whilst the legs are held together by a pair of T-shaped clamps 33. The former comprises a chamber 5, Figs. 4, 5, into which steam may be led through a pipe 9, surrounded by a perforate casing 7, communication from the chamber to the casing for eventual discharge into the garment, being through a passage 12, an air-controlled valve 13 and feed passages 14. Condensate is collected through a pipe 10. The plate 24 and the clamps 33 are pneumatically operated from a foot pedal 30. The clamps may also be automatically controlled, along with the steam and air supply, through an electrical system of motor-driven cams and relays. This system comprises cams 49 ... 53 which operate in sequence such that cam 51 actuates the air valve 34 controlling the clamps 33 simultaneously with the cam 52 which operates to allow steam to pass from the chamber 5 to the garment through the casing 7. A third cam 49 then operates a switch 47 to cut out the motor starting switch 54 but the motor continues to operate as a fourth cam 50 cuts in another motor control switch 48 before the switch 54 is opened. After a period, e.g. 20 seconds, the cam 52 stops the steam supply whilst a fifth cam 53 operates a valve to allow compressed air to balloon into the garment through the former 4. Eight seconds later the cam 53 cuts the air supply and the cam 51 operates to open the clamps 33. One second later the cam 50 opens the switch 48 to stop the motor. The former 4 may be modified by the use of a pervious bag to be blown up by the steam or air.
