Title: Transmission Neutral Control Mechanism
IPC: F16H61/42
Filed: 1967-10-27
Abstract: 1,164,869. Hydrostatic transmission control. INTERNATIONAL HARVESTER CO. 27 Oct., 1967 [27 Oct., 1966], No. 48936/67. Headings F2D and F2U. In a vehicle reversible hydrostatic transmission comprising a reversible variable-displacement swash-plate pump and motor (not shown), in which the swash-plate angles are adjusted by hydraulic servo-cylinders 11, 12 controlled by cam slots 26-29 in a cam plate 25 fast on a shaft 16 carrying a pedal or hand lever (not shown), which slots act to uncover exhaust valves 30b, 31b in the servo-cylinders on rotation of the cam plate on either side of a central neutral position, the cam plate, and hence the transmission, being automatically returned to a neutral range on removing pressure from the hand lever by a spring 39, as in Specification 1,164,868, in which position, gear teeth 45 on the cam plate engage a gearwheel 46 mounted on an output driven shaft 47 by means of an overload slip coupling (50), Fig. 3 (not shown), to position the cam plate in a specific neutral position in the neutral range and prevent creep of the output. As shown, two levers 35, 36 are freely mounted on the shaft 16 (as in Specification 1,164,868) and are formed with recesses 35c, 36c co-operating with a fixed stop 41, and shoulders 35d, 36d co-operating with a pin 40 mounted on the cam plate 25. A limited amount of free play is provided between the shoulders 35d, 36d and the stop, which play defines the neutral range of the levers 35, 36 and allows the specific neutralizing of cam plate 25. The gear-wheel 46 is mounted on shaft 47, e.g. the vehicle speedometer drive shaft, by means of the overload function coupling (50) which comprises a helical compression spring (51) surrounding the shaft (47) and compressed between a fixed collar on the shaft and a pusher sleeve freely surrounding the shaft and engaging one side of the gearwheel 46 to force its opposite side against a fixed shoulder on the shaft. When the cam plate has been positioned in the neutral range, any rotation of gear-wheel 46 due to creep rotates the cam plate until the pin 40 abuts the respective shoulder 35d, 36d, when the effect of spring 39 overcomes the effect of spring (51) allowing the coupling to slip and positioning the cam plate in a specific neutral position.

Abstract: 1,166,615. Rubberized fabric laminate. DUNLOP CO. Ltd. 31 Oct., 1966 [18 Nov., 1965], No. 48974/65. Heading B5N. A method of making rubberized textile filamentary fabric comprises feeding a plurality of textile filaments 7 located side-by-side in substantially parallel relationship to one another end-on into a nip formed between a pair of rotatable rolls 1 and 2, concurrently feeding at least one layer 5 of unvulcanized rubber in a stretched condition into the nip, rotating the rolls to form a strip of rubberized fabric having the said filaments extending longitudinally of the strip and relaxing said strip to longitudinally compress the filaments in the strip. The filamentary layer may be enclosed between two unvulcanized layers 5. The unvulcanized rubber is stretched by feeding it over rolls 9 and 10 rotating more slowly than rolls 1 and 2, and the relaxation of the strip is effected by feeding it over rolls 17a and 17b rotating at a speed intermediate to rolls 9 and 10 and rolls 1 and 2. A liner 12 may be temporarily laminated to the rubber. The fabric together with liner is batched on spool 20 which may be removed and placed in a curing oven prior to removal of the liner. Alternatively, a curing oven may be located between the nip rolls and the batching means.

Title: Nickel oxide and the production thereof
Inventor: ILLIS ALEXANDER
IPC: C22B23/00
Filed: 1964-06-10
Abstract: The invention comprises a form of nickel oxide having a high packing density and which is produced by heating an ammoniacal ammonium carbonate solution of nickel carbonate to precipitate from 70 to 99% (preferably 85 to 95%) of the nickel as carbonate at a rate of 0.2 to 2 (preferably 0.5 to 1) g. nickel per litre per minute, and calcining the nickel carbonate formed in an atmosphere containing free oxygen. The rate of precipitation depends on the temperature at which the solution is heated, this being preferably 170 DEG  to 250 DEG  F. Such control of the precipitation yields a product having a packed bulk density of at least 75 lb./ft.3  If the calcination is carried out at 600 DEG  to 1200 DEG  F. for a period not exceeding 2 hours, a product having an oxygen content of from 0.1-5 atomic per cent in excess of the amount required by the formula NiO and whose solubility in acids is substantially complete is obtained.  Nickel oxide according to the invention and containing less than 0.5% impurities may be obtained from impure nickel carbonate by purifying the carbonate by dissolving in an aqueous ammoniacal ammonium carbonate solution containing a soluble sulphide and separating the insoluble sulphides that are formed by reaction with the impurities.

Title: Fibre-reinforced belts
IPC: F16G5/14
Filed: 1963-12-24
Abstract: 1,087,903. Endless conveyers. OWENS CORNING FIBERGLAS CORPORATION. Dec. 24, 1963 [Dec. 26, 1962], No. 50910/63. Heading B8A. [Also in Divisions B5 and F2] In a conveyer or driving belt of elastomeric material, e.g. neoprene, chloroprene, isoprene, butadiene homopolymers, butadiene co-polymers with styrene or acrylonitride, natural rubber, or a mixture of some of these, reinforcing glass fibre cords 40 extend transversely of the belt. In a V-belt, the cords may be uniformly distributed as shown, with those in the outer layers 44 extending longitudinally of the belt, or they may be confined to a zone between the parts of the side faces contacting a sheave (Fig. 6, not shown). The termination of the cords at the belt side faces is stated to improve cooling of the interior. In manufacture, strips of uncured elastomeric material containing longitudinal reinforcing cords are arranged in layers on a cylindrical mandrel so that the cords extend parallel to its longitudinal axis, together with unreinforced layers if required. The resulting composite layer is then slit circumferentially and the resulting belts, incorporating transverse cords, are removed from the mandrel and cured. The requisite uncured strips may be formed by applying a layer (12) of elastomeric material to a mandrel (14) (Figs. 3, 4, not shown) and, while the mandrel rotates at least once, and preferably twice, feeding spaced parallel glass fibre cords (20) from spindles (22) through a guide comb (24) on to the surface of the layer (12), about which they are wound circumferentially, i.e. not helically. The reinforced layer is then cut circumferentially and axially to provide the strips. Alternatively parallel fibres may be fed into the nip of sheeting rollers (66, 68) (Fig. 7, not shown) or milling rollers (74, 76) (Fig. 8, not shown) to be embedded in a mass of uncured elastomeric material, so that they are uniformly embedded in the sheet material produced, which is then cut into strips. The surface of the glass fibres may be treated to improve adhesion of the elastomeric material, e.g. as described in Specification 1,087,902 (see Division D1).
