Title: Improvements in or relating to methods of making arcuatelycurved metal articles
IPC: B22F7/08
Filed: 1941-02-27
Abstract: 545,454. Making composite curved articles such as bearings, brakes or clutches. WELLMAN, CO., S. K. Feb. 27, 1941, No. 2673. Convention date, March 6, 1940. [Classes 83 (ii) and 83 (iv)] Curving.-An arcuately curved metal article, particularly for forming bearings, brake linings or clutch facings, having an unfractured sintered lamina 1 bonded at one face to a metal reinforcing member 2, is made by bonding metallic reinforcing members 2, 3 to opposite faces of a flat sintered lamina by bonds coextensive with the areas of contact between the lamina and the members, curving the assembly and thereafter removing one of the reinforcing members. When the lamina forms the convex surface the member 3 is removed. The members 2, 3 may be bonded to the lamina in the same or different operations and either before or after sintering. After removal of the member 3 the rough surface of the lamina is restored by grinding or sanding. The lamina is subsequently provided with rivet holes. The member 3 is usually somewhat thinner than the member 2. The members 2, 3 may be of iron and the lamina of copper. For a sintered copper lamina 3/16 inch thick, the permanent backing member may be 1/16 inch thick and the temporary member as low as 0.016 inch thick. Specification 530,904 is referred to.

Abstract: 451,222. Vacuum closures for tins &c. BARRINGER, WALLIS, & MANNERS, Ltd., and MANNERS, R., Mansfield, Notting- hamshire. Jan. 28, 1935, No. 2754. [Class 125 (iii)] In a vacuum-closed tin or like container in which the lid is hinged, the hinge being located wholly to the outside of the sealed compartment, the hinge socket extends through an aperture in the flange of the lid and embraces an integral part of the flange which serves as the hinge pin. The tin comprises a body 10, Fig. 4, with a beaded edge 13 and a flanged lid 11 with a bead 15 and recess 16 holding a packing-ring 17. The hinge sockets 22 are formed on a strip of metal 21 soldered &c. to the side of the tin. The sockets pass through a hole 23 in the lid flange. The hinge sockets may be integral extensions of the body, if the top edge is turned outward and flattened, or the metal strip may be trapped between the flattened portions. A part 122 of the hinge strip between the sockets may be provided to prevent loose movement of the hinge pin 15 when the lid is open. The packing ring is provided with a tab extending through a slot in the lid flange to facilitate the destruction of the vacuum to open the lid.

Title: Method and equipment for the application, in one continuous working operation, of atleast one layer of rubber-analogous substance to a surface and more especially to a textile sheathing
IPC: B29D23/00
Filed: 1959-01-27
Abstract: <PICT:0884773/III/1> <PICT:0884773/III/2> Continuously operable equipment for coating at least the inner surface of a textile hose with rubber or rubber-analogous substance in liquid form and capable of solidification, comprises a vertical sleeve adapted to receive the fabric, means for continuously filling the inside of the fabric up to a predetermined level, pulling means for moving the fabric gradually through the sleeve from the bottom upwards, means for ensuring stanchness at the bottom of the sleeve, and heating means for causing solidification of the coating substance at a predetermined height of the sleeve.  In Fig. 1, a textile sheathing 20 is woven by a circular loom about a mandrel 1, to the central bore of which thermo-sensitized and preferably pre-vulcanized latex is fed from a reservoir 12.  The mandrel 1 is provided with a seal 14 to prevent downward escape of latex.  A sleeve 7, provided with heaters 8, surrounds the sheathing 20, and is carried by a bracket 15, vertically movable on the threaded spindle 16 of a motor 17. During normal operation, the sleeve rests at the lower limit set by a switch 19, partially surrounding the mandrel 1; but if the loom is stopped, it is raised to the upper limit 18.  The exterior of the sheathing may be coated by the apparatus of Fig. II, in which latex is supplied by pipes 32, 33 to the interior of a housing 31, sealed below by flexible diaphragms 34, 35, between which a slight air-pressure is maintained.  A smooth-surfaced sleeve 38, e.g. a glass tube, is fixed to the housing 31, and its upper part is surrounded by a heat exchanger 40, which may be supplied with hot water.  The coated sheathing is then dried in a hot-air chamber.  (see Group XIII).

Abstract: 954,381. Thermal switches. KING-SEELEY THERMOS CO. Jan. 26, 1961, No.3058/61. Heading H2B. [Also in Division G3] The control unit for an electrical cooker comprises two bi-metallic or tri-metallic elements 36, 46, the element 36 being heated by a heater winding 32 whilst the element 46 is self-heating together with a heater winding 48. When heated the element 36 moves a peg 38 which co-operates with a slot 39 in a member 40 to rotate the member 40 to move a contact 42 thereon relatively to a contact 44 carried by the element 46. The heater winding 48 causes the element 46 to cycle to make and break the contacts 42, 44 whereby to control the element which exerts the final control on the cooker. A connector 72 is connected across part of the element 46 whereby the " self-heating " of the element is affected to cause the contacts 42, 44 to be made for a predetermined minimum duration. The element 46 is carried by a bracket 58, a manually operated knob 62 being provided to adjust the bracket 58, and hence the element 46, so that the unit operates at the desired temperature. The initial calibration of the element 46 is carried out by means of a toothed rack 148 on the bracket 58. Operation of the knob 62 also moves a slider 52 of a potentiometer 50 which is in series with the heater winding 48 on the element 46 whereby its operation can be modified. The set operating temperature is indicated by a pointer 51. The element 36 has two calibrations, one in which the carrying bracket can be moved by means of a toothed rack 134 and the other in which a bracket 120 secured to the tip of the arm 112 is adjustable by means of a toothed rack 128 to move the tip of the arm. The element 46 can be initially adjusted by means of a toothed rack 148. A pointer 43 moves with the member 40 to indicate the internal temperature of the article being cooked. Specification 954,382 is referred to.

Abstract: 906,103. Filters. CLAYTON DEWANDRE CO. Ltd. Jan. 21, 1960 [Jan. 29, 1959], No. 3252/59. Class 46. Hydraulic oil to be filtered enters at 3, Fig. 1, and passes laterally through a pleated paper element 23 (optionally impregnated), Fig. 7, (sectional plan), the pleats being spaced by embossing of the material before pleating, or by independent separators, or by means incorporated in or applied to the material. Preferably the element is formed in sections providing coarse and fine filtration respectively, and is thus equivalent to two elements in parallel. The element is secured at its ends 28, 29, Fig. 7, two of the perforate walls of a container 20 by adhesive and the assembly then secured to bottom and top covers 30 and 31 by adhesive. The casing 1 is divided into inflow and outflow sections by an endless strip of felt 24 around the container 20. When bolts 15 are unscrewed to remove the casing 1, transfer ports 7 and 8 in the head 2 are automatically closed by plugs 13 on the bolts 15, which are spring-loaded at 14. Alternatively, Fig. 5, each transfer port is closed by a spring-loaded valve 32 when a spring clip 35 is moved prior to removal of the casing 1. The element is secured non-reversibly in brackets 26 depending from the head 2. A by-pass relief valve operates on clogging or when the element is isolated for examination or change. The filter is located in a pump suction line. A flow-limiting valve may be mounted on the head.

The conveyer may be troughed longitudinally and may be guided so as to form a transverse pocket to receive water, which in this case may be supplied by an adjustable water bath into which the pocket dips. If the material is to be granulated the pocket is made of increased capacity, the conveyer is inclined upwards, and, to assist in drying the material, the air heated by' the molten material may be drawn through a casing surrounding the conveyer. The conveyer may be a continuous band or formed of separate parts coupled together and may have corrugations or projections to stiffen the conveyer and retain the materials thereon.
