Inventor: TURNER PHILIP WILSON
IPC: F16F1/38
Filed: 1952-04-29
Abstract: 799,601. Hinges. SPENCER, MOULTON FLEXITOR, Ltd. Nov. 16, 1954 [April 29, 1952], No. 10752/52. Class 65(2) [Also in Group XXXII] A rubber torsional spring hinge for an arm 8 pivotally mounted at 5, 6 comprises a pair of rubber bushes 13, 16 having respective inner members 12, 17 and a common outer metallic shell 14 the arrangement being such that movement of the arm 8 about the pivot 5, 6 in one direction applies torsional stress to the bushes 13, 16 and varies the distance apart of the inner members 12, 17, to apply radial deflection to the bushes 13, 16. As applied to an arm 8 carrying the lid of the boot or bonnet of a motor vehicle, the inner bush 12 is rigid with a bracket 1 of the boot. The bush 17 is rigid with the arm 8. Deflection of the lid 8 thus results in a toggle-action. Alternatively, the toggle-action may be replaced by a system of cam abutments.

Title: Improvements in and relating to the brewing of beer
Inventor: BISHOP LAURENCE ROBERT
IPC: C12C3/00
Filed: 1962-03-21
Abstract: <PICT:0961506/C6-C7/1> Lupulin is segregated from dried hops by disintegrating the hops in a pin mill and then sifting the fines from the coarser particles of plant tissue.  The lipulin can then either be used as such for boiling with wort or for adding to brewed beer, or it can be subjected to extraction processes for the isolation of the respective active ingredients which can then be stored, with or without stabilization, until they are required for use.  For the sifting there may be employed a turbine sifter, gravitational or centrifugal sieving or air sifting.  A bale of dried hops is loaded off a platform 1 into a trommel 2 which is then rotated slowly so that the bracts and other parts of the dried hops fall through on to a belt conveyer (not shown) for discharging into a bin 4.  They are drawn by an air stream, produced by a turbine sifter 9, along a feed pipe 5 to a pin disc mill 6 and the disintegrated hops pass into the turbine sifter, the fines (lupulin) then pass along an outlet pipe 12 to a cyclone separator 13 for collection.

Alternatively, the tapes are provided with hooks engaging eyelets on the long or short strip, or vice versa, or the tapes are knotted after passing through the eyelets. Pockets may be provided in the strip 2 to accommodate splints. In use, the strip 2 is placed around the limb or other part, the long strip 1 being drawn tight and wound in the usual manner.
Patent GB-1412340-A (GB)
Title: Chronograph timepiece
IPC: G04F7/08
Filed: 1973-03-07
Abstract: 1412340 Chronographs EBAUCHES SA 7 March 1973 [15 March 1972] 10999/73 Heading G3T A chronograph gear train may be disconnected from the timepiece train, by which it is normally driven, by means of a clutch, both ends of the chronograph train being at the same time braked to avoid backlash in the gearing. As shown, a third wheel pinion 20, Fig. 2a, drives a wheel 19 and thus normally also a wheel 5 and a chronograph seconds hand shaft 18 which are frictionally coupled thereto by a spring 23, as in Specification 1403127. Operation of start-stop control member 29 to the "stop" position frees the wheel 5 and the shaft 18 from the wheel 19, and brakes the wheel 5 by pressing it against frame plate portion 2a. The member 29 carries conical pins 27 which produce axial displacement of a disc 26 for the declutching and braking action, and the member is displaced in alternate directions by successive operations of a pusher 48, Fig. 1. These displacements are produced by a swivelling finger 49 which acts on a reversing lever 55 as shown, or directly on the member 29. A locking lever 58 ensures that a zeroing member 35 cannot be actuated when the member 29 is in the "start" position shown, and in this position a brake lever 66 is held away from the shaft 18. Operation of the zeroing member 35 in the direction of arrow 59 uncouples chronograph minute and hour shafts 31 and 39 from wheels 11 and 17 respectively and actuates hammers 63-65 to return all three hand shafts to zero by acting on heart pieces 30, 37, 44, at the same time lifting the brake 66 off the shaft 18. The wheel 17 at the other end of the chronograph train is then braked by a four-armed resilient washer 45.

Title: Safety devices for projectile fuzes
IPC: F42C15/26
Filed: 1937-04-19
Abstract: 488,044. Projectile fuzes. SCELZO, L. April 19, 1937, No. 11159. Convention date, April 17, 1936. [Class 9 (i)] A safety device for projectile fuzes comprises a spherical mass bored diametrically and rotatable about its centre, the centre of gravity of the mass lying on or substantially on the longitudinal axis of the projectile, said mass being adapted to be brought to its armed position, in which the axis of the diametral bore coincides with the longitudinal axis of the projectile, solely by the centrifugal force due to the rotation of the projectile by the rifling of the gun barrel. As shown in Fig. 1, a spherical cavity between the body 1 of the fuze and the head 2 thereof houses a sphere 3 provided with a diametral hole containing two detonators 4, 5. A spring-actuated pin 6 engages in a small cavity in the sphere so as to keep it locked in the safety position shown in the figure. On discharge, the pin 6 sets back against its spring and, when the pressure of inertia has ceased to operate, the sphere is rotated by centrifugal force so as to bring one of the detonators to the end of the fuze head so that it is operated when the projectile strikes the target. If desired, a single detonator may be employed or the bore in the sphere can be entirely filled with detonating material. Fig. 3 shows an alternative construction employing a slightly modified form of fuze head 9 and in which the detonator 14 is located beneath the sphere 10, the bore 11 of which is empty. The hole in the nose of the fuze head may be empty or may contain a striker.
