Patent GB-2128066-A (GB)
Title: A supporting device for an agricultural machine
Inventor: VAN DER LELY CORNELIS
IPC: A01B51/04
Filed: 1983-10-06
Abstract: A supporting device comprises a frame (1) on which is mounted four wheels (2,3,4,5). The frame has coupling means (11,13) for hitching to a tractor (14) and a coupling device (16) for receiving an agricultural machine (35). The supporting device supports at least part of the weight of the machine (35), so relieving the tractor wheels (51) of some load. The device may also support some of the weight of the tractor. The wheels (2,3,4,5) of the device have wide tyres, so reducing contact pressures on the ground. <IMAGE>

Title: Fire escape chute
Inventor: RENNISON DAVID RAYMOND
IPC: A62B1/20
Filed: 1984-01-18
Abstract: An inflatable escape chute, 9, is fixed to an outside wall containing an inflatable escape chute, (FIG 1), a compressed air cylinder, 5, valves & tubes, and a release mechanism, (FIG 5), which can be operated from any point requested. Upon operation of the release mechanism the box unfolds into a protection barrier for the chute, the compressed gas is then released into the chute and the chute is then inflated up to the required pressure. Once up to pressure and the safe to use signal (whistle) is heard, the escape chute is then ready for use. The chute is fitted with a pressure relief valve. <IMAGE>

Title: Drive line for four wheel drive vehicle
Inventor: STUBBS PETER WILLIAM ROBERT
IPC: B60K17/348
Filed: 1984-05-23
Abstract: A driveline for a four-wheel drive vehicle, having a prime mover 2 and two propeller shafts 9 and 10 connected to drive front- and rear-wheels, comprises two identical continuously- variable-ratio transmissions of the belt and sheave type mounted in parallel with common rotating parts coaxial. Each input sheave 7 and 8 is driven by the prime mover output shaft. Each output sheave drives a respective propeller shaft; and a belt coupling the input and the output sheave.

Patent GB-2145465-A (GB)
Title: Device for shutting off an opening
Inventor: BRANDL JOSEF
IPC: F16K3/18
Filed: 1984-07-25
Abstract: To shut off an opening 3 a slide member 1 is initially moved at a spacing parallel to the cross- sectional plane of the opening 3 and finally pressed perpendicularly to the cross-sectional plane against a seal 4. This movement cycle of the member 1 is effected in that arranged on a side of the member 1 which is remote from the opening 3 is a sleeve 5 which has at least one aperture 9 wherein there is guided a thrust piece 10, whose end remote from the member 1 is supported on the base of the thread course 11 of a spindle 12. The thread course 11 of the spindle 12 has a pitch which reduces to zero, in which respect in the pitchless region over at least a part of one revolution the depth of the thread course 11 decreases continuously. In this region, thus, upon continued revolution of the spindle 12 the member 1 is no longer moved parallel to the cross-sectional plane of the opening 3, but conveyed by the thrust piece 10 perpendicularly thereto into the closure position. <IMAGE>

Title: Recycled fatty acid crude petroleum recovery system
Inventor: HERTER GEORGE LEONARD
IPC: C10G1/00
Filed: 1984-10-24
Abstract: A method of recovering crude oil for subsequent processing comprises the step of exposing the source of crude oil such as a subterranean petroleum reservoir or a vessel or a container of tar sands, kerogen or the like to aliphatic or carboxylic acid, preferably oleic acid, to produce a solvated crude oil mixture of reduced viscosity. This mixture is saponified by reacting it with a nucleophilic base, preferably a hydroxide of potassium or sodium, under pressure whereby to separate the solvated mixture into petroleum crude and an acid soap which migrates to an aqueous phase. The petroleum crude is separated from the aqueous soap through conventional techniques. Afterwards, a desaponification step contemplates recovery of the aliphatic or carboxylic acid for subsequent recycling in the previously mentioned exposing step. Reuse is facilitated by desaponifying aqueous soap within a high pressure containment vessel reacted with an acid suitable for donating a hydrated proton to the aqueous phase of the soap. This reconstituted acid is recycled for injection into the inputting step. Preferably carbonic acid is generated for the desaponifying step by injecting high pressure carbon dioxide within the containment vessel. By-products of the chemical reaction are separated and/or filtered as necessary to effectuate necessary purification sub-steps.

Title: Gas-fired cooking appliance
Inventor: ALLEN THOMAS
IPC: F24C3/12
Filed: 1986-02-18
Abstract: A gas-fired cooking appliance (e.g. a hob) has a pivoted cover. A user-operable control valve and a safety cut-off valve (10) control a flow of gas to a burner. Within valve 10, a flap is operated to close the inlet 11 by a push rod connected to the cover, so that gas is turned off whenever the cover is closed. In addition, an electromagnet 21 is energised via switch 23 whenever the (or any of the) operator controlled gas taps is turned on. The electromagnet is effective to latch the flap in the closed condition whenever the cover is closed while a tap is left on, and will not restore the gas supply after opening of the cover until the tap is turned off. This prevents inadvertent escape of gas if the cover was closed without turning off the tap. <IMAGE>

Title: Electric motors and power tools
Inventor: WARD RICHARD
IPC: H02K29/06
Filed: 1986-02-19
Abstract: A hand power tool comprises an electric motor 40 having a rare earth permanent magnet rotor 3 and a polyphase wound stator 4 within a totally enclosed body 5, which in turn is mounted within a housing 2 of the hand tool. The rotor 3 is covered with a thermally and electrically insulative sleeve 12. Primary and secondary output shafts 42 and 49 rotate in the same sense, but one at twice the speed of the other. Thus, no bearings in the motor have to deal with an angular speed greater than half the actual rotor speed. Associated with the motor 1 is electronic control circuitry arranged to generate a polyphase alternating supply and to connect that supply to the stator 4, thereby to produce a rotating magnetic field. Means are disclosed of cooling the rotor, and various electronic circuit configurations are disclosed, for the motor control. <IMAGE>

Title: Sound attenuating flooring system
Inventor: MACKENZIE R ROBIN KENNETH
IPC: E04F15/20
Filed: 1988-05-24
Abstract: A floating raft floor on top of concrete slab or timber joist structural floors is designed to attenuate the transmission of both airborne and impact sound. This system comprises chipboard or timber flooring 4 laid upon and nailed or screwed to a series of timber battens to which laminated closed 7 and open cell 6 foam strips have been bonded. The open cell structure of the open cell foam 6 permits the attenuation of acoustic energy in the cavity between the battens by dissipation within the interstices of the foam itself. The open cell structure of the open cell foam also allows air contained within the interstices to be expelled under dynamic load and thus permits a proportionately high vertical deflection in relation to the thickness of the material to be achieved. In addition to the airborne sound attenuation properties, the floor also provides the resilience necessary to isolate impact sound from being transmitted into the structural floor. The battens 5 may be laid on a timber sheet 3 supported on joists 2. <IMAGE>
