Title: Improvements in or relating to springs made from rubber or like elastomeric material
IPC: B61F5/14
Filed: 1968-07-05
Abstract: 1,221,830. Laminated spring unit. PNEUMATIQUES, CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBERCOLOMBES. 5 July, 1968 [5 July, 1967], No. 32357/68. Heading B5N. [Also in Divisions B7 and F2] A spring unit, consisting of layers 10 of elastomeric material alternating with metal layers 11 bonded to the adjacent elastomeric layers, is wider at one end (the bottom as shown) than the other; but it is so proportioned that each elastomeric layer is of the same stiffness as the others both in (horizontal) shear and in (vertical) compression. Figs. 5 and 6 are respectively side and end elevations of one possible structure, the uniformity of stiffness from layer to layer being achieved by reason of the central aperture 14. In Figs. 3 and 4 (not shown) the side elevation is similar to Fig. 5 but with the central aperture terminating at the next-to-top elastomeric layer; the end elevation is rectangular, i.e. does not taper as does that of Fig. 6. In Fig. 7 (not shown) the central aperture breaks through all the layers, the resulting structure comprising two sideby-side columns inclined toward each other from bottom to top. The spring units are stated to be flexible in both shear and compression but resistant to bending. Figs. 1 and 2 (not shown, but see Division B7) depict spring units of the above described form embodied in a rail vehicle suspension.

Abstract: 801,747. Hedge cutters. TELES SMITH, Ltd. Nov. 6, 1956 [Nov. 14,1955], No.32506/55. Classes 6(2) and 6(3). A hand-held motor-driven cutter for trimming hedges and bushes, comprises a rigid toothed blade 3, a saw chain carrying teeth, a saw guide plate 6, and means for transmitting the drive to the chain. The rigid blade 3 is secured by set screws at 2b in a slotted bracket on an extension 2 of the casing 1 of an electric motor, and has an aperture to receive the end of a shaft on which a sprocket 5 is mounted to drive the saw chain. At its outer end, the blade 3 has an aperture to receive the spindle of a disc 5a. The saw chain has toothed links 4 connected by plain links 4a. The saw guide plate 6 is secured to the fixed blade 3 and serves to keep the chain teeth in contact with the blade; on its inner side it is grooved to accommodate the chain linkage of the saw, and is held down by straps 6b and bolts 6c. A narrow plate 7, secured between the two rows of chain links, acts as their support. A three-link chain (i.e., with double connecting links) may be used, and the chain teeth may be bevelled as at 4b or square. The plate 6 may be in two longitudinally separate parts, and the blade 3 may have slots for the bolts 6c to permit longitudinal adjustment.

Title: Improvements in and relating to electric heating units
IPC: H05B3/48
Filed: 1938-11-09
Abstract: 521,248. Electric resistance heaters. BRITISH THOMSON-HOUSTON CO., Ltd., and SIMS, W. J. Nov. 9, 1938, No. 32544. [Class 39 (iii)] In an electric heating unit of the sheathed wire type, the -tube 2 is initially diamond-shaped, Fig. 1 (Comp.), and the resistance unit 1 is flattened and of nearly the same width as the tube. After the resistance and insulation are inserted, the tube is swayed or rolled to compact the insulation and deform the tube to an oval shape, Fig. 2 (Comp.), with a flat upper surface for good contact with a cooking vessel. The coil is closer to the upper surface which thus reaches a higher temperature. The Provisional Specification also describes a form in which the sheath 2, Fig. 3 (Prov.), is symmetrical about both axes before deformation, and becomes oval with the heating coil 1 in the centre after deformation, Fig. 4 (Prov.).

Filed: 1946-11-07
Abstract: 627,238. Valve circuits for radio reception; frequency modulation. BENDIX AVIATION CORPORATION. Nov. 7, 1946, No. 33167. Convention date, Dec. 13, 1945. [Class 40 (v)] Instability in the I.F. stages of a receiver, e.g. a F.M. receiver, which comprises both amplifying and limiting stages is prevented by the interposition of a frequency multiplying stage in the chain. The Figure shows in block schematic form a F.M. receiver in which instability due to coupling between the output and input circuits of the I.F. amplifier stages 12 and 13 is prevented by a frequency-multiplying stage 18 which ensures that the output and input signals are at different frequencies. A second multiplier may be introduced between the I.F. amplifier stage 13 and the limiter stage 14 and the gain may be increased by additional I.F. amplifier stages each being separated from the adjacent one by a further multiplier stage.

Title: Additive-releasing filter and method for releasing additives into tobacco smoke
IPC: A24D3/12
Filed: 1964-08-14
Abstract: 1,032,330. Tobacco smoke filters. PHILIP MORRIS Inc. Aug. 14, 1964 [Oct. 1, 1963], No. 33307/64. Heading A2C. A tobacco smoke filter contains an additive ion exchange resin, the additive being released on contact with the tobacco smoke. The additive may be nicotine or it may be a flavourant. A nicotine-cation exchange resin may be prepared by contacting a cation exchange resin with nicotine. A column is packed with the ion exchange resin in particulate form and an aqueous solution of nicotine passed therethrough. Suitable cation exchange resins include sulphonic acid types formed by cross-linking polystyrene with divinylbenzine and sulphonating the cross-linked product, phosphoric acid types formed by cross-linking polystyrene with divinylbenzene and reacting the cross-linked product with phosphoric acid to incorporate a phosphoric acid difunctional group on the styrene-divinylbenzine lattice, carboxylic acid types formed by copolymerizing methacrylic acid with a cross-linking agent such as divinylbenzene, and resins having an -OH group as the ion functional group and formed by reacting polyhydric phenols with formaldehyde. Carbonaceous cation exchange resins of the sulphonated coaltype may also be employed. Suitable flavourants for use when a flavourant-ion exchange resin is to be prepared include flavourful alkaloids, amines, myosmine, or quinine derivatives. The flavourant-ion exchange resin may be anion or cation exchange resin. Suitable cation exchange resins are the same as those suitable for the preparation of a nicotine-cation exchange resin. Suitable anion exchange resin include polystyrene quaternary ammonium resins, and the primary, secondary and tertiary amines. The filter base may be e.g. cellulose acetate and may include additives such as carbon or aluminium. The additive ion exchange resin may include additives such as carbon or aluminium and may be placed between two filter base components, may be dissolved and sprayed on to a base component or may be ground to dust and added to cellulose acetate after which the cellulose acetate is made into a filter component. Quantitative examples are given.

Abstract: 669,528. Mixing appliances. SEVILLE, J. R. Nov. 24, 1950 [Dec. 30, 1949], No. 33346/49. Class 86 In the manufacture of dough and the like, means for ensuring that the desired quantity of yeast is dispersed in the desired quantity of water and added automatically to the mixing machine at the appropriate time comprises a tank a to contain a measured quantity of doughing water, a mixing vessel d having a stirrer e in which yeast and/or other ingredient is mixed with doughing water and into the lower part of which doughing water is delivered from the tank a through an outlet valve b and pipe c. The vessel d has a relatively large bore overflow pipe f and a relatively small bore siphon pipe h located below the overflow pipe, the arrangement being such that the flow of doughing water into the vessel sweeps it clear of the previously mixed contents of doughing water and yeast or the like and delivers the same through the overflow pipe f into the usual mixing machine g and when flow from the tank a has finished the siphon h establishes a definite liquid level spaced below the overflow f so that a fresh charge of yeast or the like can be added to the vessel for mixing with the doughing water therein ready for another cycle of the operation. The outlet valve b may be arranged to close automatically when the liquid level in the tank a falls to a predetermined extent. The stirrer e may be electrically operated and interconnected with the outlet valve b so that when the valve is opened the stirrer is put out of action.
