IPC: B60C15/028
Filed: 1980-11-10
Abstract: A tire 10 capable of operation inflated and deflated comprises shoulder portions 14 extending axially outward and radially inward from the tread portion to terminate in junction portions 22 from which sidewalls 16 extend axially and radially inward to rim-seating portions 18.

Title: Wheel Construction for Preventing Wheel Locking During Braking
IPC: B60B19/00
Filed: 1980-12-31
Abstract: Locking of a vehicle wheel during braking is stated to be prevented by use of an arrangement through which the tyre of the wheel is coupled to the axle hub through a stiff elastic coupling which allows a limited degree of relative rotation between the tyre and the axle hub when subjected to a large torque. This coupling arrangement can be incorporated into the wheel, as in the illustrated embodiment wherein a rim 3 has lugs 9 which act on circumferentially arranged springs 8 on a member 4 fixed to the wheel disc 2 which is secured to the hub, or it can be in the form of a separate coupling comprising a pair of annular elements between which the springs 8 are mounted and which are fixed respectively e.g. to the hub and the wheel disc. The coupling allows the tyre to perform cyclic oscillations about the wheel axis once the hub is braked. <IMAGE>

Patent GB-2062757-A (GB)
Title: Fied charge mixing device for internal combustion engines with strati/
IPC: F02B17/00
Filed: 1980-05-29
Abstract: In stratified charge engines, a gas free of fuel is introduced during a first section time in the lower part of the chamber, rotated towards the piston; in a second time fuel is added to the gas. The purpose is to provide a mixing device which allows to obtain better values for the exhaust gases and a reduced consumption. To this effect, a rotation motion is created (12, 13, 35) in the combustion chamber (6, 16) during the compression time a little before the high dead point of the piston until the high dead point is reached; the space before the spark plug (14) must be free of this rotation (12, 13, 35). This rotation provides a total homogenization of the mixture by equalizing rich and poor zones. Thereby, a uniform combustion results with a higher resistence limit to explosion.
Patent GB-2094422-A (GB)
Title: Improvements in or relating to differential gears
IPC: F16H48/26
Filed: 1981-03-10
Abstract: This invention relates to differential gears for mechanically propelled vehicles, and it is an object of the invention to reduce spinning one wheel or axle of a vehicle in icy or muddy conditions. This result is achieved by feeding oil through passages in the sun gear 13 to the meshing teeth of the sun gear and the planet wheels 5. Thus, if one wheel or axle starts to spin, there will be relative rotation between the sun gear and the planet wheels which will then act like a gear pump. The sun gear and the planet wheels are located in a relatively confined space so that the rate at which the oil can be dissipated is limited. The load caused by the oil pumping limits rotation between the sun gear and the planet wheels, and enables torque to be applied to the slipping wheel or axle. Additional gear wheels in mesh with the planets but not with the sun or annulus may be provided to improve the pumping action. <IMAGE>

Title: Vehicle Battery Charging Apparatus
IPC: B60K25/10
Filed: 1981-04-24
Abstract: A vehicle's storage batteries are automatically charged by utilising the available energy, which dissipates in a moving vehicle's suspension arrangement. Fluid pumps are fixed to the underframe and the pumps operating mechanism is connected with the axles or suspensions to be operated by the inter-action of the vehicle's weight and vertical travel of the road wheels. The pumps are double-acting and deliver pressure fluid at the deflection and rebound progressions of the suspension springs. A sequence of rigid and flexible pipelines, incorporating a pressure control valve convey fluid from the supply tank to feed the pumps and direct the pressed fluid from each pump into a pipe manifold to unite and emerge as a single stream into the intake of a hydraulic turbine. Spent fluid returns to the supply tank. The turbine is coupled to an electric alternator in circuit with control apparatus and the vehicle batteries.

Title: Improvements in shelf assemblies
IPC: A47B96/02
Filed: 1981-06-24
Abstract: In a corner shelf assembly a shelf member (8) is supported between two upright panels (which define the corner) by aligned elongate horizontal brackets 3, 4 secured to the panels. Each bracket has a serrated tongue which is slidably received in a groove (9) in the shelf member (8), and a continuous upper flange which overlies the upper surface of the member (8) so that the member (8) is mounted against movement in a transverse direction. An "L"-shaped locking member (12) has a vertical web inserted in the corner between a chamfered edge (10) of the member (8) and the intersection of the panels. A flange (14) thereof overlies the member (8), and a peg (15) is received in an opening in the member (8). Longitudinal movement of the member (8) is prevented by the engagement of the web (13) with the inner ends of the brackets (3, 4). In an alternative construction (not shown) a separate headed screw projects through the opening in the shelf member and is screwed into a tapped hole in a flange of the locking member which overlies the lower surface of the shelf member. <IMAGE>

Patent GB-2113598-A (GB)
Title: Heat exchanger maintenance
Inventor: FORREST JOHN
IPC: B23P19/02
Filed: 1981-12-15
Abstract: A method of separating a tube bundle from a heat exchanger casting or shell consists of employing a first withdrawing apparatus to effect initial separation or 'breakout', and a separate second withdrawing apparatus to effect completion of separation. The first withdrawing apparatus constitutes a heavy duty puller and is designed using a thrust ring and part-circular tube plate engaging elements for even distribution of breakout forces to minimise risk of damage to parts of the heat exchanger. The second withdrawing apparatus constitutes a lighter structure incorporating a step-by-step extractor for pulling the tube bundle out and on to cradling elements. Withdrawal by the method is therefore accomplished in two stages, the first by a relatively high force over a short distance, the second by a relatively low force over a long distance. <IMAGE>

Filed: 1982-01-30
Abstract: The combustion characteristics, e.g. valve timing, combustion chamber design and capacity, of groups of engine cylinders differ so that the torque/speed characteristics of the engine when driven by one group of cylinders is different from the torque/speed characteristics of the engine when driven by the other group or groups of cylinders. Control means selectively controls fuel injectors or carburettor throttle valves to direct fuel to all the groups of the cylinders when the engine is operating under high loads but only to one or some of the groups when under low loads, the groups being selected in accordance with engine speed so that the efficiency of the engine under low loads is optimised.

Title: Shaft assembly in a ducted fan gas turbine engine
Inventor: PERRY DERICK ALFRED
IPC: F01D5/02
Filed: 1982-02-02
Abstract: In the event of breaking of the shaft which connects turbine and fan, it is essential to retain the fan in the engine and to prevent the turbine blades being flung off the turbine each in one piece, so as to maintain peripheral damage at a minimum. The invention achieves this by using one shaft (24) to connect turbine and fan (12) and another shaft (26) to axially fix the fan to axially fixed engine structure (28, 30, 32) which itself provides a path to earth (34) for working loads to pass along. If the fan shaft (26) breaks, fan (12) and turbine stay connected, so avoiding overspeed, but the turbine can still move rearwards to break up its blades against other axially fixed structure. If the turbine shaft (24) breaks, it can move as described, but the fan (12) is held in situ by its shaft (26) and fixed structure (28, 30, 32, 34). <IMAGE>

Title: Spraying apparatus
IPC: B05B7/04
Filed: 1982-02-12
Abstract: A spraying apparatus has an inlet 2 for compressed air, an inlet 3 for water, at least one inlet 4 for a fluid additive and a discharge outlet 11. Passage means direct the flow of air, water and fluid additive from the inlets such that the flow of air is brought together with the flow of water and fluid additive and such that the latter flow is drawn into the flow of compressed air upstream of the discharge outlet. The passage means is such that the velocity of air is caused to increase where the flows are brought together and the resulting mixture has a high exit velocity from the discharge outlet. <IMAGE>
