Title: Disc brake assembly
Inventor: BUTLER HENRY JAMES
IPC: F16D55/224
Filed: 1960-10-19
Abstract: 992,058. Disc brakes. DUNLOP RUBBER CO. Ltd. Oct. 11, 1961 [Oct. 19, 1960], No. 35786/60. Heading F2E. A disc brake comprises a disc 1, a pad 5 of friction material pivotally associated with a pressure member 7 and directly bearing on a bracket 2 which is adapted to take the braking torque when the brake is applied and the disc is rotating in its normal direction, and means for angularly moving the pressure member 7 and so applying the brake. As shown two substantially rectangular friction pads 5 are each secured to one limb 6a of a T-shaped carrier 6, the other limb 6b of which is secured to a pressure member 7 by a bolt 8b, the hole 9 through the carrier for the bolt being oversize to enable the carrier to move angularly. For normal applications of the brake the braking torque is taken directly on the bearing surfaces 12 of the bracket. If necessary a light strap which engages the side of the pad or carrier opposite the bearing surface 12 may be provided to prevent excessive angularly movement of the pads when the brake is applied with the disc rotating in the opposite direction. The brake is applied by angular movement of the members 7 the projections 11 of which bear on the carrier 6. A cranked lever 14 is pivoted at one end of one of the members 7 and has its apex 15 connected to the other member 7 by a tension member 22. The other limb 16 of the lever 14 is provided with a cam surface 17 with which co-operates a cam follower 18 that is located on the end of a link 19 pivoted to the first member 7 and secured to the end of a cable 20, tensioning of which applies the brake. A piston and cylinder or like fluid-pressure mechanism may alternatively be provided to move the members 7 towards one another. The ends of the members 7 remote from the brake applying means may be interconnected by means which automatically compensate for wear and also retract them from the disc 1 after each braking operation. Specification 709,305 is referred to.

Title: Improvements relating to apparatus for measuring the profile of gear teeth
Inventor: CROOK ALFRED WILLIAM
IPC: G01B/
Filed: 1957-11-29
Abstract: 846,404. Gauging shape of gear teeth. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 25, 1958 [Nov. 29, 1957], No. 37314/57. Class 106 (2). A device for testing the profile of the surface of an involute gear tooth p comprises a probe n mounted to move on the circumference of a circle whose centre O lies on the circumference of the base circle of the involute curve defining the tooth surface, the probe n being constrained to move in a plane perpendicular to the generators of the tooth being tested. The probe n is mounted on a frame j, k, l, m, the arm jm of which rests on the tip of a nearby tooth and is adjusted, by use of a semi-silvered mirror mounted on the arm, to lie along a radius of the gear-wheel. This is accomplished by adjusting the arm until the reflection of the teeth shown in the mirror coincides with the direct view of other teeth obtained through the unsilvered portion. The frame is also angularly adjusted to lie in the required plane, and the length ln is made equal to the length mo. Deviations of the probe from the circle are indicated electrically or mechanically and recorded on a graph on which the theoretically correct movements have already been plotted, thus giving an indication of the shape of the tooth under test.

Abstract: 786,858. Clamps for fork lift trucks. SHARP, J. R., KAYE, E., and ARNOT, A. E. R. Dec. 21, 1955 [Dec. 24, 1954], No. 37346/54. Classes 78 (3) and 78 (4). Release of the load-engaging clamp 16 of a lift truck is prevented by the force needed to keep the load in the lifted position. As illustrated the pressure in the lifting ram 15 is conveyed to a relay valve 56 where it moves a plunger 58 against a biasing spring 59 to close the conduit 55 leading from the ram 17 operating the clamp 16. The lifting ram 15 is controlled by a pair of coupled valves 31, 35 controlled by a handle 37 and connecting the ram to a pump 21 or to the reservoir 23. Two similar pairs of valves 47, 48 are controlled by a single handle 46 to deliver liquid to the double-acting clamping ram 17. A relief valve 52 limits the pressure of the clamp on the load. In an alternative arrangement (Fig. 2, not shown) the relay piston 58 serves to open contacts in the circuit of solenoids operating valves controlling the clamping ram 17.

Abstract: 1442160 Mixing apparatus W LODIGE F LODIGE and J LUCKE 8 Aug 1973 [12 Aug 1972] 37509/73 Heading B1C In a machine for continuously mixing glue and particulate material such as shavings or fibres of wood, bagasse or, especially, cellulose containing materials and comprising a stationary drum 15 having a discharge flap 27 opened by pressure of the mix against a weight 28, and a rotary shaft 19 coaxially disposed in the drum and having adjustably secured thereto radial stirrer arms some of which are adjacent the flap 27, each arm comprises a ploughshaped head 11 and a body 10, the head and body tapering inwardly towards one another, adjacent their junction, in a plane including the axis of the shaft 19. Preferably, in respect of each arm, the ratio of the radial lengths of the head 11 and the tapered section of the body 10 is 1:3, and the ratio of the maximum axial head width to the outer diameter of the non- tapered section of the body is 0.5-1.5:1. The inner end of each arm is adjustably threaded into the shaft 19 and locked by a nut 20. Cooling fluid is fed through a pipe 22 disposed coaxially of the shaft 19 into pipes 23 disposed coaxially of the arms to be centrifugally pumped to impact on rear inner surfaces 25 of the heads 11 and be forwardly deflected towards the head noses 21 before return outwardly of the pipes 23, 22. The plough-shaped heads 11 act to deflect the mix laterally and radially inwards. The taper surfaces, 16, of the bodies avoid a strong forward pressure and act to deflect the mix laterally and radially outwards with a pressure which increases with increasing radial depth of the mix, such that an increase in fill increases the pressure on the discharge flap and hence accelerates drum emptying so that radial depth of the mix may remain constant despite variation in throughput. The arms adjacent the discharge flap are provided with deflectors 35 to provide additional outward pressure on mix which exceeds a maximum thickness.
