Title: Improvements relating to motor vehicle suspensions
IPC: F16F1/36
Filed: 1960-10-27
Abstract: 886,372. Road vehicle spring suspensions. GENERAL MOTORS CORPORATION. Oct. 27, 1960 [Nov. 6, 1959], No. 36891/60. Class 108(2). Two swing axles 6, 8 have a common pivot 10 supported by a pillar 14 pendant from and pivotally movable relatively to the sprung portion 4 of the vehicle which is also connected to one of the axles by a longitudinal resilient strut 66. In the preferred embodiment, the strut is formed by a leaf spring with its forward end anchored in a rubber bush 70. A second strut 44 anchored in a resilient buffer 54 and to a rubber bush in the lower end of the pillar 14 provides resistance to lateral movement of the suspension. The connection 26 consists of a horizontal flange secured to the pillar 14 and sandwiched between a pair of rubber buffers while the pivot 10 comprises a rubber bushed sleeve. Each axle is additionally connected with the frame by a thrust link 56 having a ball joint 60 at one end and a rubber bushed pin joint 62 at the other.

Title: Electrical heater device
IPC: H05B3/14
Filed: 1974-08-22
Abstract: 1525851 Resistance heating fabric ISOPAD Ltd 13 Aug 1975 [22 Aug 1974] 36936/74 Heading H5H [Also in Division Dl] An electric heater comprises a woven fabric having a weft formed of resistive yarn, a warp of insulating yarn, and at least two spaced electrodes extending warpwise to electrically engage the resistive weft yarn. The weft yarn may be formed completely of conductive yarn. The conductive yarn is formed of organic polymer fibres to which conductive particles are adhered, or of organic polymer fibres coated with and/or penetrated by conductive particles or a metallic film. In the latter example the conductive yarn is formed from conjugate fibres, i.e. spun fibres composed of two fibre forming polymeric components arranged in distinct zones across the cross section of the fibre wherein one component forming a portion at least of the peripheral surface of the fibre has a lower softening temperature than the other. The components may be side by side, one may form a sheath for the other, or one may form one or more lobes of a multilobal fibre. Carbon conductive particles may impregnate the conjugate fibres or graphite particles or metallic film may be coated on a conjugate fibre. The warp may be formed of glass fibre. The electrodes may be formed of flexible strips, mesh, wires or fibres and may be attached to the fabric by stitching or preferably by including them in the warp along the selvedges of the fabric. Copper or aluminium tabs are attached to the electrodes by carbon loaded epoxy resin, by stapling or by crimping. The fabric may be embedded in a heat conductive insulating sheath of polythene terephthalate or rubber. Where the electrodes are formed by warp wires the linear heat shrinkage of the conductive weft yarn is greater than the non-conductive warp yarns to'ensure good electrical contact between the weft and the electrodes after heat treatment.

Title: Bag shaping and bag top forming apparatus
IPC: B65B43/52
Filed: 1972-08-09
Abstract: 1372788 Shaping and closing bags; endless conveyers BEMIS CO Inc 9 Aug 1972 [17 April 1972] 37205/72 Headings B8C and B8A  An apparatus for shaping and forming the top of a bag before the bag is closed by sewing and/or taping comprises a V-trough conveyer 12 opposed side conveyers 19, 24, a gate 29 forming an extension of the side conveyer 24 and which is reciprocable by a double-acting piston and cylinder assembly 33, 34 in the directions 100 and 102 between a retracted position (shown in full lines, Fig. 3) and an extended position (shown in broken lines), and an assembly 45 mounted above the conveyers 12, 19, 24 for forming gussets in the top of the bag and bring- ing the tops of opposed side walls of the bag together. The assembly 45 includes a sub-frame 48 mounted for vertical movement by parallel linkages 46 and a double-acting piston and cylinder assembly 49. Parallel rods 50 which are slidably mounted on the sub-frame 48, are movable by a double-acting piston and cylinder assembly 54 and themselves slidably support fixed fingers 66, 68 and pairs of transversely spaced fingers 58, 63 movable by doubleacting cylinder and piston assemblies 56, 61. Once formed the folded bag top is held in position by longitudinally extending bars 82 which are moved by double-acting piston and cylinder assemblies 77 and linkworks (80, 81, Fig. 4) to engage opposed sides of the gusseted bag top. The bag top then passes into the nip of opposed conveyer belts 89. The operation of the apparatus is controlled by an electric circuit incorporating limit switches operable by the bags and parts of the apparatus (Fig. 6). In operation empty bags are withdrawn from a magazine, moved laterally towards the rearward end of conveyer 19 and clamped to a filling hopper. The gate 29 is then moved to its extended position and in conjunction with a stationary bracket 38 and the conveyer 19 limits the bulging of the bag as it is filled. Once the filled bag has been dropped on to the V- trough conveyer 12, the gate 29 is retracted at the same speed as the bag is conveyed by the conveyers 12 and 19. The interior of the bag is then engaged by the fingers 58, 63 and the exterior of the bag by fingers 66, 68 so that upon moving the fingers 58, 63 apart the bag top is gusseted as shown in Fig. 5.

W, Ti Zr or Pb, a selenide of Mo or W, boron nitride, calcium fluoride or colloidal silver, PTFE, polytrifluorochlorethylene, nylon, a polymer or copolymer of propylene, a polyimide, poly-(paraoxybenzoyl), or a mixture of these. The silanols may be formed in situ by hydrolysis of the corresponding trialkoxysilanes, which simultaneously provides at least part of the alcohol needed. Suitable acids are hydrochloric, acetic, chloracetic, citric, benzoic, dimethylmalonic, formic, glutaric, glycollic, maleic, malonic, toluenesulphonic and oxalic. Condensation catalysts, preferably buffered, may be added to the composition. Examples are potassium formate, dimethylamine acetate, ethanolamine acetate, dimethylaniline formate, tetraethylammonium benzoate, sodium acetate, sodium propionate, sodium formate and benzyltrimethylammonium acetate. Some of these too may be formed in situ by reaction between the acid and free alkali in the colloidal silica. Conventional additives may also be present, e.g, carboxymethylcellulose, corrosion inhibitors. dyes and oxidation inhibitors.

Class 98(1)  In an improvement in or modification of a photographic camera as claimed in claim 1 of the parent Specification the exposure value setting member is limited in its travel relative to one of the other setting members by means of co-operating driving connections whereby when the one setting member is urged beyond its range of adjustment the driving connections establish a direct drive intermediate the exposure value setting member and the one setting member so that the other setting member is adjusted thereby. As shown and as described in detail in the abridgment for the parent Specification, an exposure value setting member (ring or slide) 1 is coupled to a diaphragm setting member 5 and an exposure time setting member 4 by means of a differential gear mechanism. The co-operating driving connections comprise a driver projection 25 on the exposure time setting member 4 and two stops 26, 27 on the exposure value setting member 1, the arrangement being such that when, during adjustment of member 1 to change the exposure value setting an index mark 12 carried by the member 4 reaches one of the limits of the diaphragm aperture scale 14, one of said stops engages with the projection 25 and the exposure time setting member 4 becomes directly driven by the member 1 instead of through said gear mechanism.
