Patent GB-2081634-A (GB)
Title: Improved apparatus and method for shearing metal stock
IPC: B23D23/00
Filed: 1981-06-29
Abstract: The apparatus comprises first ind second dies 50, (52) having bores 51, (53) respectively of equal radius extending therethrough between substantially parallel faces thereof and bearings in which the first and second dies are journalled for face-to-face rotation about a common axis (56). The common axis (56) is eccentric with respect to a centerline through the bores. Counter rotation takes place between a position (57) in which the bores (51, 53) are axially aligned to form a common bore for receiving the metal stock 43 and positions (51', 53') and (51'', 53'') in which the bores are not aligned. At least one of the dies 50, (52) is rotated by a pinion and a ram driven rack between aligned and non-aligned positions. A variable stroke reciprocable clamp feeds the stock into the common bore (position 57) and supports the stock during counter-rotation of the dies. <IMAGE>

Title: >Friction-effection Extrusion
IPC: B21C23/24
Filed: 1981-07-27
Abstract: In an extrusion apparatus, two passages, each defined in part by a groove 5 in wheels 1, 3 and in part by a fixed shoe 7, lead to a common passageway from which a die orifice extends. Material, such as aluminium, is fed in rod form into each of the passageways and it is forced into the common passageway and out of the die 17. The direction of movement of the material through the die is opposite to the direction of the material along the passageways and, in this way, impurity material, which might finish up just under the surface of the product, and thus cause a bad surface finish, is buried towards the centre of the product, thereby avoiding bad surface finish. <IMAGE>

Title: Improvements in artificial limbs
IPC: A61F2/76
Filed: 1981-03-03
Abstract: An artificial foot and ankle assembly has a foot (1,2), an ankle joint and a shin-connecting socket (7). The ankle joint includes a uniaxial resilient bearing (5) with a shaft (4) to which the foot is connected and an outer shell (6) clamped to the socket (7).

Title: Automatic control of a fuel supply system for multi-cylinder engine
Inventor: MOWBRAY DORIAN FARRAR
IPC: F02D41/40
Filed: 1982-12-13
Abstract: A fuel supply system for a multi- cylinder engine comprises a plurality of engine operated pumps supplying fuel to the injection nozzles respectively of an engine. Each pump has an electromagnetic valve which must be closed to cause delivery of fuel by the respective pumps. The supply of power to the windings 20 of the valves is effected by a power module 21 controlled by a distributor circuit 22 which receives sequence signals to ensure that the valves are closed at the correct time and a fuel level signal to ensure that the valve is closed for the correct length of time. In order to ensure that the amount of fuel delivered through each nozzle is the same a sensor 26 provides a pulse signal at each working stroke of the engine. The period between each signal is determined by a timer circuit and the average of a number of periods is obtained from an averaging circuit. The average period is compared at 32 with the actual value and any error is used in a compensating circuit 29 to adjust the time the respective valve is closed. The circuits 30, 31, 32 may be provided by a microprocessor. <IMAGE>
Patent GB-2113663-A (GB)
Title: Catenated phosphorus material
Inventor: KUCK MARK ALLEN
IPC: H01L51/05
Filed: 1982-12-22
Abstract: High phosphorus polyphosphides, namely MPx, where M is an alkali metal (Li, Na, K, Rb, and Cs) or metals mimicking the bonding behavior of an alkali metal, and x = 7 to 15 or very much greater than 15 (new forms of phosphorus) are useful semiconductors in their crystalline, polycrystalline and amorphous forms (boules and films). MP15 appears to have the best properties and KP15 is the easier to synthesize. P may include other pnictides as well as other trivalent atomic species. Resistance lowering may be accomplished by doping with Ni, Fe, Cr, and other metals having occupied d or f outer electronic levels; or by incorporation of As and other pnictides. Top contacts forming junction devices doped with Ni and employing Ni as a back contact comprise Cu, Al, Mg, Ni, Au, Ag, and Ti. Photovoltaic, photoresistive, and photoluminescent devices are also disclosed. All semiconductor applications appear feasible. These semiconductors belong to the class of polymer forming, trivalent atomic species forming homatomic, covalent bonds having a coordination number slightly less than 3. The predominant local order appears to be all parallel pentagonal tubes in all forms, including amorphous, except for the monoclinic and twisted fiber allotropes of phosphorus. Large crystal monoclinic phosphorus (a birefringent material) in two habits, a twisted fiber phosphorus allotrope and a star shaped fibrous high phosphorus material are also disclosed. Single and multiple source vapor transport, condensed phase, melt quench, flash evaporation, chemical vapor deposition, and molecular flow deposition may be employed in synthesizing these materials. Vapor transport may be employed to purify phosphorus. The materials may be employed as protective coatings, optical coatings, fire retardants, fillers and reinforcing fillers or plastics and glasses, antireflection coatings for infrared optics, infrared transmitting windows, and optical rotators. <IMAGE>

Title: Fluid flow control systems
Inventor: WARD RICHARD
IPC: E21D23/26
Filed: 1983-03-18
Abstract: A control system is provided for controlling fluid flow to a fluid- operated device, particularly hydraulic rams of chock-type supports of coal mining equipment.

When the motor is switched off the valve returns to an opposite operational position. Alternatively d.c. motor (4) is driven from a local storage battery which is trickle charged from the power supply (1). The valve (3) latches in one operational position and the motor is used to drive the valve into and out of this position. In each case the valve (3) may be a ball valve. <IMAGE>

Title: Cashbox closure mechanism
Inventor: SCHUPP HORST
IPC: G07F9/06
Filed: 1983-11-16
Abstract: A cashbox for collecting money in an automatic sales machine is positively closed upon being removed from the machine and can then serve as a transport container for the money. When the cashbox is inserted, a stationary pin 23 mounted on the housing of the machine engages the cashbox cover, and, by way of slide tracks 24,27, displaces a slide member 6 which opens entry openings 7,8 for receiving money and closes same again upon the cashbox being removed. The slide member 6 has pawls 15 which engage teeth 17,18 on a container portion 1 of the cashbox, lock the slide member 6 in position and prevent further insertion into the box. The slide member 6 is positively reset by a spring 21 when the cashbox is opened for emptying thereof by eg pivotal movement of the cover about a spindle 3 thereby disengaging the pawls 15 from the teeth 18. The slide member 6 and the pawls 15 are made from one piece. <IMAGE>
