Abstract: 1,103,016. Bearings; lubricating. SOCIETE GENEVOISE D'INSTRUMENTS DE PHYSIQUE. 14 Oct., 1966 [26 Oct., 1965], No. 45976/66. Heading F2A. A slide 1, Fig. 1, having a pocket 3 therein which is supplied with pressurized fluid, is supported by a member 2, the pressurized fluid being supplied from a source 6 and which is connected to the pocket 3 via a throttle 5 and a pipe 4, the pipe 4 being connected by means of a pipe 9 to a by-pass 7 provided with a safetyvalve 8 so that in the event of the throttle 5 becoming blocked, the pocket 3 is supplied with pressurized fluid from the by-pass 7. In a modification, the throttle 5, Fig. 2, and the safety-valve are combined. The throttle 5 is formed in a valve-body 12 which is slidably received in a tube 10 and connects to a pocket 3 via a bore 18 in the valve-body 12, a chamber 15 in the slide 1 and a passage 17 therein. The valve-body 12 is provided with a frusto-conical surface 13 which is forced against an end of the tube 10 by means of a spring 14 in the chamber 15. The other end of the tube 10 has a drainscrew 11 therein which, when screwed inwardly, opens the valve formed by the surface 13 and the tube 12. In use, pressurized lubricant is supplied at 6, is passed through a pipe 16, through the annular space between the tube 10 and the valve-body 12 and through the throttle 5 &c. to the pocket 3. In the event of the throttle 5 becoming blocked, the valve-body is forced downwards against the action of the spring 14 and lubricant passes between the surface 13 of the valve-body 12 and the tube 10 to the chamber 14 from where it passes through the passage 17 to the pocket 3. The valve-body 12 vibrates when the valve opens and acts as a sound warning to indicate that the throttle is blocked.

Title: Improvements in and relating to disc brakes
Inventor: TAYLOR WALTER ROBERT
IPC: F16D55/00
Filed: 1961-12-22
Abstract: 1,008,073. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Dec. 14, 1962 [Dec. 22, 1961], No. 46013/61. Heading F2E. A disc brake having at least one pair of opposed pads for engagement with opposite faces of a disc has brake applying means comprising two or more cylinders of which at least one is arranged at each side of the disc, the cylinders being associated with movable members which are slidably or pivotally mounted, and are so arranged in relation to the cylinders and pads, that both pads are applied whether fluid is supplied to only one of the cylinders or to both cylinders simultaneously. In one embodiment, Fig. 1, the movable members consist of superposed plates 6, 7 of U-shape which are slidable on flanges 3 of an underlying fixed support, guided by bolts 8 on the flanges 3 engaging slots 9 in the members. A cylinder 13 is secured to the closed end 11 of member 6 and its piston 15 acts on backing plate 21 of one pad 19 arranged adjacent one face of a disc 4, and another cylinder is secured between the limbs of member 6 so as to abut the backing plate 21 of another pad 20, its piston 16 engaging the closed end 12 of member 7. The peripheral portion of the disc engaged by the pads is partially accommodated in cut-outs 5 in the underlying support, and openings 24 are provided in the plates 6, 7 for this purpose and also to provide abutment surfaces 25, 26, for engagement with plates 21 of the pads 20, 19, respectively. As a result, when fluid is applied to cylinder 13 alone, piston 15 applies pad 19 and the reaction acts via member 6 on the pad 20, while if fluid is supplied to cylinder 14 alone pad 20 is applied directly and the reaction acts via piston 16 and member 7 on the pad 19. Fluid can be supplied to both cylinders when greater braking force is required. In a modification (Fig. 3, not shown), cylinder 14 is reversed so that its piston faces the pad 20, the cylinder body being then secured to the closed end 12. In a further modification, Fig. 5, the movable members are superposed plates of closed loop form supported on flanges 29 of an underlying support and pivotally mounted on one of the flanges 29. The arrangement and operation is otherwise similar to that of Fig. 3. Specifications 996,612 and 998,726 are referred to.

Title: Filter tipping device
IPC: A24C5/47
Filed: 1965-11-01
Abstract: 1,103,330. Making mouthpiece cigarettes. AMERICAN MACHINE & FOUNDRY CO. 1 Nov., 1965 [9 Nov., 1964], No. 46073/65. Heading A2C. Groups consisting of two cigarette lengths, an interposed double filter and a connector strip are rolled between a drum carrying the groups and a co-operating series of rotating rollers, the axes of which are disposed in a circle. A suction drum 2 draws a web of connector material1 passed a cutter 4 where connector strips 7 are formed, and grooves 10 on the drum receive abutted groups 9 of cigarette lengths and interposed filter tips from a delivery drum 8. The drum 2 rotates in a clockwise direction. The groups are rolled by an assembly comprising a drum surface 44 rotating in a clockwise direction and a series of rollers 45, the axes of which are arranged in a circle around shaft 62 and which rotate around the shaft 62 in an anti-clockwise direction relative to drum surface 44. Each roller 45 rotates on its own axis in a clockwise direction. The relative speed of rotation of the rollers round the shaft 62 is such that each roller arrives in the proximity of the drum 2 immediately in advance of a group containing groove 10 and rotation of the roller on its own axis initiates rolling. As the group emerges from the groove 10 by reason of the initial rolling, the rolling is continued between the drum 2 and drum surface 44, the rolled group finally being pushed away from the nip between the drums by the next roller 45 which in turn initiates rolling of the next succeeding group 9. Relative rotation of the surface 44 and rollers 45 serves to continue rotation of the groups as they are pushed around the drum surface 44 under guides 72 to a discharge drum 76. In a second embodiment, Fig. 8 (not shown), the drum surface 44 is replaced by a second set of rollers, rotating in the same directions as the rollers 45 and arranged in a concentric circle therewith so that a group being rolled is engaged on both sides by a roller.
