Title: Improvements in or relating to operating mechanism for disc brakes
Inventor: CHOUINGS LESLIE CYRIL
IPC: F16D65/14
Filed: 1952-10-07
Abstract: 718,231. Disc brakes. AUTOMOTIVE PRODUCTS CO., Ltd. Oct. 19, 1953 [Oct. 7, 1952], No. 25138/52. Class 103(1) In a spot type disc brake hand operation is carried out through a rod or cable 38 coupled to an arm 37 adapted to rotate a disc 33 having on one face conical pits 35 containing balls 34 disposed therebetween and similar pits 36 in the rear wall of a housing member 31. When the disc 33 is rotated the balls co-acting with the conical pits apply a thrust in one direction to a sleeve 39 and in the other direction to the casing 31. The thrust on sleeve 39 is transmitted through rods 41 and 26 and cup-shaped member 27 to apply friction pads 20 to one face of the disc, and an equal and opposite pull is applied by the casing 31 through the tube 30, cap 23 and U-shaped member 18 to the friction pad 19 so that the disc 10 is gripped between the two pads. Fluid pressure operation is provided by a piston 24 within a cylinder formed within the member 18, the piston acting through the member 27 on pad 20. The disc 33 has a ratchet wheel 46 rotatable therewith, the wheel 46 having both a pawl 47 which tends to turn the wheel during return movement of the brake and acts to provide automatic wear adjustment, and a holding pawl 48. In another embodiment described the alternative fluid pressure actuator acts through the lever 37 and cam disc 33.

Title: Improvements relating to suction cleaners
IPC: A47L5/32
Filed: 1950-10-16
Abstract: 673,626. Suction cleaners. HOOVER, Ltd. Oct. 16, 1950 [Oct. 25, 1949], No. 25153/50. Class 8 (i) In a suction cleaner of the handle-propelled type having means for adjusting the nozzle from a normal operating position to a high operating position, automatic return of the nozzle to its normal position if it was previously in its high position, is effected by movement of the handle to and from a storage position. Adjustment from the normal to the high nozzle position is effected by relatively downward displacement of front wheels 33, Fig. 2, mounted on off-set ends of a shaft 43, one end 37 of which is shown as engaging in a recess 5, Fig. 4, of a cam 55. When the cam 55 is raised about a pivot 56 by depressing upwardly biased pedal lever 45 pivoted about a pin 46, the shaft end 37 is brought into register with a cam recess 58 and the nozzle assumes its high position. To restore the nozzle to its normal position, the handle 25 is moved upwardly to its storage position whereupon a pin 66 secured to the motor casing integral with the handle rocks an arm 65 rigid with the wheel shaft 38 to displace the end 37 from the recess 57, and further raise the nozzle to its inoperative position whilst allowing the cam 55 to be returned to its normal position by a pedal biasing spring 51. Thus when the handle 25 is next brought into the propelling position the pin 66 becomes disengaged from the arm 65, and the end 37 engages the recess 58 which corresponds to the normal nozzle position. The cleaner may have a convertor port 21.

Title: Improvements in automatic envelope making machinery
Inventor: VOYSEY RONALD GEORGE
IPC: B31B19/00
Filed: 1948-09-27
Abstract: 646,625. Making envelopes. CARMICHAEL & CO., Ltd., P. Sept. 27, 1948, No. 25176. [Class 94(ii)] Mechanism, for making envelopes from paper blanks comprises a plunger 7 reciprocable downwards into and upwards out of a folding-box (not shown), a swinging folding-plate 8 adapted to receive an envelope blank carried down through the box by the plunger, means (not shown) for folding down the flaps of the blank during the upstroke of the plunger, the plate being periodically operable to swing down into a position from which the envelope is ejected and to return to the normal position before the plunger again reaches the bottom of its stroke, means for positively ejecting the envelope from the folding-plate as the latter swings down, and a rotatable suction roll 10 adapted to receive the ejected envelope and to transfer it to a drying conveyer 11. Upon completion of the folding operations a cam 18, which rotates counter-clockwise, reaches a position in which it allows a spring 20 to rock a link and lever system controlling the folding- plate, the latter swinging to the position shown. Meanwhile a cam 22 has turned counter-clockwise to a position in which it allows a spring 29 to rock a link and lever system controlling fingers 28, the latter turning counter-clockwise about a pivot 26 to'enter slots formed in the folding-plate to eject the folded envelope, shown in heavy line, on to a suction roll 10 where it is held near its leading edge by suction ports 45. Immediately thereafter a cam 31 reaches a position in which it allows a spring 38 to rock a link and lever system controlling a gate 36, the latter falling to the position shown in which it prevents the envelope from leaving the suction roll. Suction is cut off from the ports 45 when the latter pass the horizontal position and is then applied momentarily to a succession of small ports as these pass the horizontal position. The envelope is thus lowered into a space between the teeth of a conveyer 11. When the last of the small ports passes the horizontal position the envelope is released and is carried away by the conveyer to a drying hood. Specifications 646,624 and 646,626 are referred to.

Title: Improvements in or relating to ammonia evaporation plant particularly for refrigerated transportation systems
IPC: F25B33/00
Filed: 1947-09-19
Abstract: In a stationary plant for separating ammonia from a strong aqueous solution formed in the absorbent holder of a mobile refrigerated container as described in Specification 639,271, [Group XIII], strong solution is introduced into a tower 10 through a tube 22 and falls through bubble-trays 71 where it is met by water vapour rising from the foot of the tower heated by a coil 11, the ammonia being thus distilled out of the strong solution, the ammonia vapour being led by a pipe 16 to the bottom of a similarly constructed rectifying tower 17 down which flows condensed ammonia, the rectified ammonia then proceeding to a condenser 28 from which part flows back to the rectifying tower and part flows to a storage tank 29.  The bubble trays are pierced by several short pipes 73 having perforated conical hoods 74. Vertical fall pipes 72 feel liquid down the tower from tray to tray.  Weak and strong solutions are withdrawn from the bottom of the distilling and rectifying towers respectively and the top of the tower 10 is fitted with a cooling coil 76.  Connections 37 (Fig. 1) are connected to the absorbent holder on the mobile container and strong solution flows by a pipe 36, three-way valve 35 and pipe 38 to check-valves 39, 40 controlling the input to tanks 41, 42 which are connected by linked three-way valves 48, 50 to a pump 46.  The pump 46 sucks solution into one of the tanks 41, 42 and discharges solution from the other through a pipe 45 to a storage tank 18 from which solution is pumped by a pump 21 through a heat-exchanger 23 and a <PICT:0641000/III/1> <PICT:0641000/III/2> pipe 22 to the tower 10. In the distilling tower, ammonia is driven off and passes through the rectifier 17 to the condenser 28 from which it flows to the storage tank 29.  Water drains from the tower 10 by pipe 24, heat exchanger 23 and pipe 25 to a storage tank 26.  The rectifier 17 is fed with condensate by a pipe 30 and drains to the tank 18 by a pipe 32. Non-condensable gases are removed from the tank 18 by a pipe 62 to a tank 64 where they are washed by water from the tower 10 entering by pipe 69 and leaving by pipe 65, the gases being snifted through pipe 67.  To charge a mobile container with anhydrous ammonia and water, connections 37 are connected to the absorbent holder and hoses 61 to the refrigerated holder.  Refrigerant, i.e. ammonia, flows from the storage tank 29 by pipe 51, precooling coil 58 and pipe 57 to the connections 61, some refrigerant being byepassed through a float control 54 to cool the coil 58 in a chamber 53, vapour being returned to the tank 18 by pipes 56, 45.
