Patent GB-2133078-A (GB)
Title: Vaporising and supplying LPG
Inventor: ELLIS FRANK
IPC: F02M21/02
Filed: 1982-12-01
Abstract: Liquid petroleum gas is supplied to a first chamber (2) from a pipe 1 and passes to a second chamber (12) via a valve (11) controlled by a pressure sensitive actuator (16, 17, 18) to be closed when pressure within the second chamber (12) reaches a predetermined value, a heat exchanger (15) vaporising the liquid fuel and a third chamber (24) receiving the vaporised fuel from the heat exchanger (15) via a valve (26) which opens to allow the vaporised fuel to enter a supply duct (25) to an engine carburettor when the pressure at the end of the said supply duct (25) is below atmospheric. An actuator (29, 30) operated manually or by solenoid enables valve (26) to be opened to supply fuel for starting. A filter 5 is provided in chamber (2) and is covered by a cap (6) which forms a stop valve openable by a solenoid actuator (7). <IMAGE>

Title: Method of stabilizing the position of workpieces in ring rolling
Inventor: HEINRICH PETER
IPC: B21H1/12
Filed: 1982-12-06
Abstract: The invention relates to a method of stabilizing the position of workpieces in ring rolling, more particularly for the manufacture of rolling bearing rings. The workpiece 2 is so shaped, in relation to the rolling gap profile, that centring edges 5 of the workpiece 2 centre it only on one tool, i.e. mandrel 4 or roller 1. Deformation takes place only at such edges 5 in a first phase of the deforming operation. The deformation is so large that axial forces operating on the starting part cannot displace it axially. <IMAGE>
Patent GB-2111955-A (GB)
Title: Rotary collating and/or sheet inserting machines
Inventor: WATKISS CHRISTOPHER R
IPC: B65H39/041
Filed: 1982-12-21
Abstract: In a rotary collating and/or inserting machine where individual sheets are peeled from the bottom of a plurality of stacks of sheets arranged spaced around a circle on a table and are moved down through one or more radial slots in the table, the separation of the bottom sheet of each stack, preferably at a corner, is initiated by creating changes in air pressure in a cyclically controlled manner at or adjacent to the upper region of at least one slot. This can be accomplished by the provision of suction holes along the length of at least one slot or by changing the contour of the table surface, such as by incorporating a bellows. To aid onward movement of a sheet into a slot after initial separation from the stack, the initial suction effect which either acts directly on the sheet or changes the contour of the table surface is shut off or reversed as the bottom sheet passes down through the slot. Cyclically controlled suction devices are preferably provided at or adjacent to the lower region of each slot.

Title: Axial Securing Element
Inventor: BAUER WALTER
IPC: F16C35/073
Filed: 1983-06-27
Abstract: A axial securing element 3 for fixing two workplaces in relation to each other consists of a ring 3 of rectangular cross- section having conical external surfaces set obliquely at an angle of less than 90 DEG  to the engaging surfaces on the work pieces and designed to change their diameter so that they can be fitted into notches on the work pieces 1, 2 as shown in fig. 8. To enable them to take up exceptionally high axial forces, the ring is made up of at least two part-elements 3a, b, c (fig. 2) or 3d, 3e (fig. 8) which can be placed into position independently of each other but cooperate with each other. These part-elements may consist of ring segments (fig. 2) obtained by sub-dividing a ring at its circumference or they may consist of split part-rings of different mean diameters (fig. 8), with the internal and external contours so adjusted to each other that the part-rings fit into each other with the surfaces facing each other. <IMAGE>

Patent GB-2150682-A (GB)
Title: Space heating of barrier structures
Inventor: BISHOP ROGER IVAN
IPC: F24D3/18
Filed: 1983-10-12
Abstract: A barrier structure, such as a building, which is heated by use of a heatpump in which the absorbing element 3 is enclosed within insulating material, 2 and 4, and is placed in a position to absorb escaping heat energy passing from the interior, heated space 5, to the exterior unheated environment 14. The heat absorbing element is maintained at substantially the external environmental temperature so that no heat energy passes to the environment. Imported energy to drive the heatpump mechanism is arranged to just balance the unavoidable heat losses due to air changes and waste water etc. Since the heat energy is recirculated without the use of any other heat source, the imported energy is therefore low. The effect is to multiply the insulating material thermal resistance by the heatpump efficiency (times 3 to 6). <IMAGE>

Title: Monostable circuit uses non-saturating transistor switches
Inventor: SMITH GREGORY J
IPC: H03K4/56
Filed: 1985-07-25
Abstract: A voltage to frequency converter (1) includes a very high accuracy one-shot monostable circuit (2) that determines precisely the duration of the reset period of a sawtooth waveform generated by an integrating circuit (3,4,6,8). The high precision one-shot circuit utilizes emitter coupled transistors (35,36) which establish a very precise initial voltage on a capacitor (26) in the one-shot circuit by means of non-saturating transistor switching circuitry (27), which also decouples the source of the initial voltage from the one-shot capacitor (26) to allow linear discharging of the capacitor. A precise final reference voltage is compared by a comparator (20) with the linear discharging voltage on the capacitor (26) in order to produce a comparison signal which terminates the one-shot pulse by resetting a flip flop (17) that causes the source of the initial voltage to be re-coupled to the capacitor (26). <IMAGE>

Title: Fire resistant pile fabrics
Inventor: MARTIN DAVID WILLIAM
IPC: D06M11/34
Filed: 1987-10-01
Abstract: A process is provided for the production of fire resisting pile fabrics by the conversion of readily flammable precursor pile fabrics, which comprise entirely of polyacrylonitrile fibres in the pile, into pile fabrics which then consist substantially of so called oxidised polyacrylonitrile fibres in the pile. This is effected by subjecting the pile fibres of the precursor pile fabric to the hot drawing action of a rapidly rotating heated and fluted roller followed by the heating of the pile fabric in air at a temperature of 225 +/-5 degrees Celsius for a period of from 5 hours to 7 hours. Pile fabrics so treated incandesce under incident flame. There is little smoke release or fibre melting. The excellent initial properties of thermal insulation and resistance to attack by microorganisms are retained. Pile fabrics so treated retain these desirable properties following exposure to severe elemental conditions and following repeated field maintenance procedures such as washing and dry-cleaning.
