Abstract: 1,044,955. Winches. A. BRUSSELLE. Aug. 9. 1963 [Aug. 14, 1962], No. 31598/63. Heading B8B. [Also in Division F2] Twin drums 50, Fig. 2, of a fishing winch are driven from a' main shaft 90 through a pair of claw clutches 52, 53 having teeth which permit a limited lostmotion to an extent necessary for both clutches to be engaged during slow rotation of the shaft whilst both the drums 50 are held stationary by brakes. The arrangement is of particular use when the clutches are to be controlled remotely. In Fig. 5 (not shown), the gap a in the clutch member 52 must be greater than twice the width b of a claw on the member 53 plus the width c of the claw on member 52 so that the lost-motion is greater than the combined widths (b+c) of the engaging claws. The driving gear 91 for the main shaft 90 incorporates a torquelimiting device 93 to prevent overloading in the event of abrupt clutching.

Title: Improvements in or relating to breathing apparatus
Inventor: WILLIAMS STANLEY EDWIN
IPC: B64D13/02
Filed: 1962-08-18
Abstract: 981,128. Breathing apparatus. NORMALAIR Ltd. Aug. 19, 1963 [Aug. 18, 1962], No. 31786/62. Heading A5T. A breathing apparatus for supplying a plurality of users with oxygen, comprises for each user, a demand regulator and an air inlet valve set to open at a differential pressure greater than the differential pressure required to actuate the demand regulator, a metering device being provided in the oxygen supply line to each regulator, a bypass oxygen supply line being connected by conduits to each oxygen supply line downstream of the metering device and a non- return valve being positioned in each of said conduits. As shown, a suitable apparatus comprises a control unit 35 and units 10 joined together, each of the units being connected by a pipe connector 23 via a demand regulator (not shown) to a face mask (not shown), each mask having an air inlet valve (not shown). A main supply oxygen line 18 and a by-pass oxygen line 19 runs through the units 35 and 10. In control unit 35, line 18 is connected to line 19 by a conduit which is normally closed by valve 37, held in closed position by a spring, and gas pressure supplied by way of a bleed from the supply line, acting on diaphragm 38. Each unit has a metering device 21 adjacent the supply line 18 and in the passage 20 which leads to connector 23. Line 19 is connected to passage 20 which is normally closed by spring controlled valve 32. In use, on inhaling, the demand regulator is opened and oxygen is supplied by line 18 via orifice 21 and passage 20 to the face mask. If the supply is not sufficient, the inlet valve in the face mask opens and atmospheric air enters. But in emergency conditions, or in very low pressure ambient conditions, this may not be sufficient, in which case valve 37 is opened by the opening of manually-operated valve 40 or barostaticallycontrolled valve 39, which means that the pressure acting on diaphragm 38 is vented to the atmosphere and the oxygen supply pressure opens valve 37 against the spring. Oxygen now passes into line 19 and the pressure in line 19 is sufficient to open valve 32 in unit 10 to allow oxygen to pass via passage 20 to the face mask without passing through orifice 21. U.S.A. Specification 2,914,067 is referred to.

Title: Improvements in or relating to gas meters
IPC: G07F15/02
Filed: 1934-11-08
Abstract: 447,121. Prepayment mechanism for gas meters. BINGHAM, J. H., 17, Private Road, Sherwood, and METROPOLITAN GAS METERS, Ltd.; Hyson Green, both in Notting- ham. Nov. 8, 1934, No. 32132. [Class 27] In a prepayment gas meter having screw-andnut quantity mechanism and operable optionally by more than one value coin, movement of a coin slide in the coin holder, when a coin is being inserted, releases means, normally operative, for locking the nut guide or screw whichever of these is stationary during the valveclosing operation, while movement of the slide in the coin-ejecting direction occasions return of the locking means to operative condition. As shown applied to the mechanism described in Specification 418,465, wherein according as a penny or a shilling is inserted, a wheel 11 or a wheel 10 is rotated by a tooth 13 or 12 on a pivoted dog plate 14, the rotation being transmitted through differential gearing to the screwed spindle 6, the wheel 11 is normally locked by a tooth 16 on the end of a rod 17 carried by an arm 18 which is mounted on a push rod 19. The rod 19 is constrained by a spring so that its front end engages and follows a cam 20 on the rear edge of the coin-slide in the coin holder 1. When a coin is inserted, the rod 19 is pushed back by the cam to cause the tooth 16 to be disengaged from the wheel 11 and allow the screw 6 to be rotated. When the coin is discharged, the wheel 11 is again locked and rotation of the screw 6 during the valve - closing operation is prevented. To prevent backward rotation of the coin holder and the screw 6, a small pinion 21 is provided meshing with a wheel 5 of the mechanism and loosely mounted by means of an oversize bearing 24 on a pin 22. If an attempt is made to rotate the wheel 5 backwards, the pinion 21 slides on the pin 22 into engagement with a fixed pin 23.

[Class 12 (i)] A bearing, such as a ball bearing, has a cover engaged by a spring which also engages the opposite face of the bearing or an opposite cover. In one form, Fig. 3, the outer race 17 is axially slidable in a sheet metal housing 14 and is engaged by two covers 18, 19 held together by a spring 20 having arms 23 with projections 24 entering slots in arms 21 on the inner cover 19. The arms 23 pass through slots in the wall 25 of the housing 14 so that they can move axially but not rotate. In a modification, Fig. 9, the arms 31 of one cover have laterally open or closed slots engaged by a plate spring 37 which bears against the other cover, the spring having projections 35 near its ends to prevent longitudinal displacement. The spring may engage either the outer or the inner cover, and in the latter case it is apertured or laterally slotted to pass the shaft. In another form, Fig. 11, the spring 45 has limbs 46 with inwardly bent ends 49 and also has a central aperture so that. it may be placed against either the inner cover 43 or the outer cover 44, the ends 49 engaging the other cover. This assembly of bearing and cover fittings may be inserted as a unit in the bearing housing which is axially slotted to receive the limbs of the spring and so prevents any tendency to rotation of the outer race and cover fittings. The spring may be so formed as to serve also as a cover.
