Patent GB-1053895-A (GB)
IPC: F16D23/06
Abstract: 1,053,895. Positive clutches. REGIE NATIONALE DES USINES RENAULT. Feb. 24, 1964 [Feb. 26, 1963], No. 7643/64. Heading F2C. In a balked frictionally synchronized clutch, shown as a double clutch for selectively connecting change-speed gears 2, 3 to a shaft 1, the preset, balk and synchronizer functions are performed by elements which only become operative for performing their particular function. Dog teeth 10 on the gear 2 are clutched by splines 9 in a sliding dog sleeve 8 splined to a hub 4 fast on the shaft 1. A balk ring 12 has three internal radial lugs 16 engaging with lostmotion 25, axial slots 17 in the gear 2, and compression coil springs 22 load the balk-ring 12 axially right so that, in the neutral position, when it is out of contact with the dog sleeve 8 the end face 19 of the ring is in frictional contact with the end face 20 of the shaft hub 4 so that relative rotation between the gear and shaft sets the lugs 16 to the appropriate circumferential end of the slots 17 whereby pointed teeth 18 on the ring are registered with pointed ends of the dog teeth 10, but axially spaced 26 therefrom in a position pre-set for balking. Leftward engaging movement of the dog sleeve 8 engages coned surfaces 15 on the sleeve 8 and ring 12, taking the ring left to absorb the axial spacing 26 and bring the ends of the teeth 18 into balk contact with the teeth 10, at the same time separating the end face 19 of the balk ring 12 from the face 20 of the shaft hub 4, so that these pre-set surfaces are no longer operative. Rightward axial reaction on the ring 12 is now taken in part by frictional engagement between the side faces of the ring lugs 16 and the slots 17 under synchronizing torque. On synchronism these side faces separate permitting the lugs 16 to centralize in the slots 17 as the teeth 18 followed by the sleeve teeth 9, move into full engagement with the teeth 10.

Abstract: 1,095,342. Tunnelling. A. W. LAWRENCE. April 19, 1966 [Jan. 22, 1965], No. 2930/65. Heading E1F. To limit the starting power required to recommence tunnelling by a tunnelling machine the machine is so constructed that the boring head, when not being rotated to cut away a face of a tunnel, may be advanced forwardly a limited distance relatively to the forward end of the shield in which it is housed to press against the face. This action prevents creepage of the face into the boring head and shield, and, when the head is subsequently withdrawn into the normal relationship with the shield on recommencement of tunnelling allows an easy start up of the machine.

In a washing machine, a door 3 which gives access to a rotor basket 2 is prevented from being opened for a predetermined time after the discontinuation of the active centrifuging step by a pneumatic delay mechanism which is fed with air under pressure from a fan 19 which rotates during the centrifuging stage. The door opening mechanism comprises a rod 5 which is adapted to be pushed downwardly, in order to open the door 3, by means of a pivoted push-button 6. The delay mechanism includes a spring-pressed pivoted lever 11 which blocks the downward movement of the push-button 6 to prevent the door 3 from being opened. The delay mechanism also includes a flexible bellows 21 with a lower collar 21A and an upper movable collar 21B to which is attached a tube 25 having a calibrated hole 27. A tube 15 connects the interior of the bellows 21 with the fan 19, which may be the cooling fan of the centrifuging motor. A valve 23 is provided at the upper end of tube 15. Lever 11 carries a feeler 9 which is adapted to co-operate with a programming cam 7 having recessed portions which allow the lever 11 to pivot out of its blocking position under the action of a spring 12. When the fan 19 is rotating, air is supplied to bellows 21 and the pipe 25 is maintained in its upper position, shown in Fig. 2, thereby preventing lever 11 from moving from its blocking position under the influence of spring 12. When fan 19 stops, the bellows 21 collapses slowly so that tube 25 descends to allow lever 11 to move to an unblocking position.

Abstract: 1295101 Determining thickness of sheet material LICENTIA PATENT-VERWALTUNGS GmbH 19 March 1970 [22 March 1969] 13410/70 Heading G1M [Also in Division B8] An apparatus for testing the thickness of sheets comprises a parallel pair of rollers 5, 6 between which the sheet to be tested is passed, one roller 6 being biased towards the other roller 5, the rollers being spaced apart by the required sheet thickness by an annular contact rib 6<SP>1</SP> on one roller 6 contacting a part on the other roller 5 away from the part of the roller 5 which carries the sheet, and an electric circuit including the rollers which is broken between the rollers to cause an output signal from the circuit when the rollers are parted by a sheet of increased thickness. As described, roller 3 and two rollers 5 are coaxial. Belt 1 on roller 3 brings sheets e.g. bills of paper money to the rollers and belts 8, 12 carry the sheets from the rollers. The belts are recessed below the sheet contacting surfaces of rollers 5.Bushings 7 insulate rollers 5 from roller 3. Roller 6 is mounted in a pair of rocker arms 10 pivoted on a support structure (46), Fig. 1 (not shown) to permit the roller to move out of contact with rollers 5. Roller 6 comprises electrical contact portions 6<SP>1</SP> which contact rollers 5, bearing portions 38 and sheet contacting portions 42. The separation 11 between sheet contacting portions 42 and roller 5 is greater than the thickness of one bill, but less than the thickness of two bills. Electrical contacts 21, 22 may run on electrically separated portions of one roller as shown in Fig.2 or may Fig.4 (not shown) run on different rollers. Whichever arrangement is used, a sheet of increased thickness lifts the top roller breaking the contact between 6<SP>1</SP> and 5. In the circuit shown, Zener diode 17 is normally short circuited through the rollers; when contact is broken the whole voltage passes to the Zener diode which provides an output signal at 18. Condensor 16 prevents the output pulse issuing when a short period break in contact occurs, for instance as a result of a speck of dust on a sheet.
