Title: Improvements in and relating to retreading of tyres
Inventor: KENT JAN HERBERT FARQUHASIN
IPC: B29D30/54
Filed: 1962-10-22
Abstract: 973,764. Retreading tyres. KENTREDDER Ltd. Oct. 22, 1963 [Oct. 22, 1962], No. 39877/62. Heading B5A. In the retreading of a rigid breaker tyre, the new tread 1 is first placed in the mould and then expanded against the mould by a member 10 which may be a smooth surfaced conventional tyre casing having an air bag therein. The mould may be warmed to assist the tread rubber to take up the form of the mould. The casing is then removed and the tyre to be retreaded placed in the mould. Specification 732,241 is referred to.

Abstract: 981,779. Punching. HOUDAILLE INDUSTRIES Inc. April 7, 1961 [Nov. 1, 1960], No. 40292/64. Divided out of 981,775. Heading B3W. A punching machine includes a frame having a bed and a reciprocating ram, selectively - replaceable, relatively - reciprocable co - operating punch and die tools supported respectively by an upper tool support and by the bed and a pair of connections having separate axes and acting between the tool support and the frame, at least one of the connections being individually detachable and operative to guide the tool support into the position where the tools are in accurate alignment. A punching machine including the upper tool support comprises a C-shaped frame 31 having upper and lower arms 31a and 31b respectively. The lower arm 31b supports a sub-table 50, on which is mounted a work supporting table 33, and also supports a bed 38 on which the lower tool is mounted. A punch and stripper assembly 40 is supported by an upper tool support 41 which is held to the upper arm by clamps 42 and 43. The support 41 comprises arms 41a and 41b and between them is a reciprocating shaft 47 continuously driven by an eccentric 46 and selectively coupled to a ram 44 by an electrically operated clutch of the type described in Specification 890,250. Upper tool support clamping mechanism.- The arms 41a and 41b of the upper tool support are held against the frame 31a by two similar clamps 42 and 43 so that the upper tool is accurately aligned with the lower tool. Each clamp comprises a pivoted hook 157 which engages a pin 158 in a support arm and draws the arm against a locating face on the frame. The hook is operated by lever 155 having a handle 155a and having cam disc 159 which enters a recess in the hook. A plunger 168 on the handle operates a normally open microswitch 171 on the frame when it reaches the closed position. The machine cannot be operated unless both the micro-switches are closed. If either clamp is released the upper tool support can be pivoted about the pin 158 engaged by the other clamp to provide access to the lower tool. An alternative structure. Fig. 3, is provided which is particularly adapted to use small-sized punches. This structure comprises an upper tool support 132 which has arms 132a and 132b extending upwardly on opposite sides of the ram 48 and having a bight portion 132c which receives and slidably supports a punch and stripper assembly 133. The supporting portions of the upper tool supports 132 and 41 are identical.

Abstract: 1399497 Indicating apparatus SANKYO SEIKI SEISAKUSHO KK 1 Sept 1972 [2 Sept 1971 25 Dec 1971 14 Jan 1972 (2) 28 Jan 1972] 40543/72 Heading G1J [Also in Division G3 and G5] In an instrument, e.g. a digital clock, having a drum or belt carrying symbols which are successively displayed through a window, the window has its upright portion(s) at an acute angle to the direction of movement of the symbols which are correspondingly formed and have adjacent halves of some or all of the symbols overlapped. Much larger symbols than conventionally can thereby be accommodated on the drum or belt. As shown windows 4a-c are provided in a mask plate 3. A drum 5, Fig.2 (not shown) carries symbols 6 in the form of numerals 0-9 arranged on centre lines a-j and overlapping. The symbols are formed by colouring the portions which are NOT to be displayed, and which are shown in full lines in Fig.4, the same colour as the mask 3. The symbols may be illuminated by a lamp within the drum (5), or by an external light source with the displayed symbol portions being painted in fluorescent paint. Areas 6A-E, where displayed and undisplayed areas of adjacent symbols overlap, produce visual defects in the form of unwanted breaks or redundant dots. These may be avoided by spacing such symbols and indexing the display drum in corresponding uneven steps Figs.9 and 10 (not shown). Other methods of avoiding such defects use light polarizing elements 17, 18 Figs. 12 and 13 (not shown) in the window and on the drum, or levers 22-25, Figs 15 and 16 (not shown) having ends which are coloured similarly to the mask 3 and are displaced in front of the latter to cover defect areas at appropriate times. As a further alternative, the mask may be formed with joining portions which retain its central shield portions and are aligned with the defect areas. Various forms of window and numerals are described, and the arrangement may be used to display letters or other symbols.

Abstract: 1479865 Electrical connectors SIEMENS AG 7 Oct 1975 [10 Oct 1974] 41112/75 Heading H2E Good electrical contact between two parts of, for example, an electromagnetic radiation shield is effected by an element 1 comprising a metallic strip clamped between the two parts and comprising a plurality of pointed resilient metallic tongues 2. At least one tongue 2 projects from each face of the strip and the tongues 2 are arranged along at least one line A, B that is substantially parallel to the longitudinal edges of the strip. The projection of at least one tongue, but not all, on to the plane of the strip point(s) in substantially one direction whilst the projection of the remaining tongues point in substantially the opposite direction. As described, the tongues, which may be in the form of isosceles triangles, alternate in their "projected" direction along a line. The points of the tongues in adjacent lines may lie on a line that is substantially perpendicular to the longitudinal edges of the strip. A pair of adjacent tongues 2c, 2d in one line A preferably project from one face of the strip, neighbouring pairs of tongues 2a, 2b, 2e, 2f, 2m, 2n in the same or neighbouring line projecting from the other face. The tongues may be curved away from the strip, a tangent from the point thereof intersecting the plane of the strip at an angle of between 15 and 30 degrees. The strip and tongues are of preferably hard flexible material, e.g. V2A steel, and may be coated with a good conductor, e.g. gold. In use, a double edged adhesive foil 4 may be used to position the element 1 on one part, allowing clamping to proceed by tightening of a bolt 7, the resilient tongues 2 scratching the surfaces of the two parts to effect the electrical connection.

Abstract: 1,195,544. Sound controlled toys. REMCO INDUSTRIES Inc. 8 Sept., 1967 [8 Sept., 1966], No. 41215/67. Heading A6S. [Also in Division G4] A sound actuated switch in or for a toy comprises a hollow resonator 40 containing a pair of contacts 29, 30 bridged by a conductive plate 50 which is vibrated by resonance-air to effect the conduction between the contacts. The plate, which is of metal or metal coated plastic, is located 'by a pin 20 and the bottom of the resonator may also vibrate so as to add to the effect of the vibrating plate. Pads 23 and 24 present conduction of unwanted vibrations through the supports. Resonators of different frequency may be mounted beneath the funnel of a toy tug-boat and in the control tower of an opening bridge. Sounds from whistles or a musical instrument cause the plates to vibrate and release a relay controlling electric motors driving wheels of the boat and the raising of the bridge. The relays may be of the stepping type so as to effect in turn forward, stop and reverse operations, or the different frequncy resonators in each toy could control respectively start/stop and forward/reverse actions or different resonators could control start and stop. The relay may have delayed in action to prevent operation by short spurious vibrations.
