The back-rest is carried by a pillar A at the base of which are fixed two sector plates L with arcuate serrations l. Two similar sector plates G are carried on a fixed member E to which the link O is connected by an eccentric pivot P. A loose member J with arcuate teeth K, M surrounds the link and is connected thereto by a pin T which passes through holes U of slightly larger diameter than the pin. An L-shaped member R can slide to and fro beneath the pivot P and its shorter arm r, connected to the pin T by a helical spring S, fits against the outermost of the flat surfaces Q formed on the eccentric pin P. A sleeve D surrounds the pin and acts as a bearing. A handle O secured coaxially to one end of the pivot P controls the locking and unlocking of the link. As in Fig. 2, when the pivot pin P is in the position indicated by P1, the teeth of the two sets of sector plates are forced into contact with those on the loose member J and the link, plates and back-rest are all locked in position. Rotation of the handle causes it to snap over into the other extreme position P2 and owing to the eccentric action, the two sets of plates move away relatively to each other and the loose member J, owing to the action of the spring S, moving out of contact with the two sets of arcuate teeth, the link C and arm A are free and can be moved to the desired position and there secured by the reverse operation. The other parts of the underside of the chair are as described in Specification 326,835, [Class 52 (ii), Furniture for sitting &c. upon].

Abstract: 1386065 Extrusion coating of twin conductors BRITISH INSULATED CALLENDER'S CABLES Ltd 13 Sept 1972 [13 Sept 1971] 13827/74 Divided out of 1371211 Heading B5A For use in apparatus for extruding a covering 14 on two or more parallel coplanar conductors including at least one with insulation 12, a die set comprises an outer die 21 of circular bore 22 and an inner die or point 31 having adjacent its outlet end a circular external section which, with the bore 22 of the outer die 21 defines an annular extrusion orifice. The bore 33 of the inner die 31, through which the conductors 11, 19 pass, has a non-circular section comprising arcuate parts 34 united by intermediate parts 35 shaped to suit the outline of the conductor assembly. The intermediate parts 35 may be re-entrant, forming a dumb-bell shaped bore. A method of manufacturing a cable comprises passing the conductors 11, 19 through the core tube of a machine having an extrusion orifice defined by the die set 21, 31, to apply a continuous overall covering 14 around the conductors, and establishing across the covering at the extrusion orifice a pressure differential sufficient to cause the covering 14 to collapse firmly on to the conductors but insufficient to force the covering back along the core tube. The resulting covering 14 is of approximately uniform radial thickness around most of its periphery, having arcuate end parts 16 united by re-entrant parts 17, and bounding a single bore 13. Preferably the pressure differential is maintained by evacuating the core tube as claimed in Specification 1,371,211; but if the covering 14 is to be treated by the application or abstraction of heat, super-atmospheric pressure may be applied via a fluid medium in a chamber surrounding the covering and sealed to the extrusion orifice, as claimed in Specification 1,386,066. The thickness of the covering 14 can be controlled by altering the throughput speed, so allowing wider tolerances on the dimensions of the dies 21, 31. It is stated that no bonding occurs between the primary insulation 12 and the covering 14, even without the use of French chalk or other preventive material, and even when the primary insulation and the covering are of the same material, e.g. PVC. Specifications 1,371,211 and 1,386,066 are referred to.

Title: Apparatus for extracting heat from disc brakes
IPC: F16D65/847
Filed: 1954-05-12
Abstract: 752,016. Cooling disc brakes. GOODYEAR TIRE & RUBBER CO. May 12, 1954 [Dec. 22, 1953], No. 13852/54. Class 103 (1). In a disc brake assembly, a hanger member 3 is secured to the stationary brake housing member 2 and carries a second plate 5 to which are adjustably secured two carrier plates 8 one each side of the rotatable axially movable brake disc 6; the carrier plates carrying one or more laminated metal disc and spacer units 10 which engage the brake disc to absorb some of the heat generated on braking to reduce the operating temperature of the brake disc 6. The brake illustrated is of the " spot-type " disc brake variety, the brake disc 6 being gripped in a known manner by friction pads which are housed in a circumferentially spaced portion of the stationary housing 2 and usually diametrically opposed to the hanger member 3. The laminated metal disc and spacer units 10 comprise a plurality of metal discs 12 positioned in spaced relationship to each other by metal spacers 13 which are of smaller diameter to the metal discs 12 but are thicker. On braking, the contact between the brake disc 6 and the laminated units will cleanse the surface of the brake disc and, due to the fact that the laminated units 10 are made of a suitable highly heat conductive metal such as copper or some of its alloys, heat generated on braking will be absorbed by the laminated units and cooled by radiation and convection due to the air currents circulating through such units. In order to continually urge the laminated units 10 into contact with the brake disc relatively light leafsprings 14 are compressed intermediate the hanger member 3 and the associated carrier plate 8. It is also stated that not only are the surfaces of the brake disc 6 cleaned by the laminated units 10 but that they also continually provide a light deposit of metal particles on the surface of the brake disc such as to increase the coefficient of friction of the brake discs. Specification 701,725 is referred to.

The duct 7 leads tangentially into the housing 1. The latter has part 6 tapering conically upwardly. The rotor is driven through belt 24 and pulley 23 by a motor and has a conical outer surface 12 on which conical blades 13 are provided, the conicity of the surface 12 and of the blades 13 being the same as that of the housing part 6. A disc 25, which may be provided on one or both sides with radial or angularly dlirected fins 25' is rigidly connected to the rotor to prevent heavy impurities in housing 1 from entering the housing 16. The radially outward location of the outlet 15 causes the discharge pressure of the purified suspension to be greater than the pressure within the housing 1 and eliminates the necessity of having a pump connected to the outlet aperture 15 or allows a lower-power pump to be used. Heavy impurities are collected periodically from the bottom of the housing into a chamber 4 via a valve 3.
