Patent GB-2231332-A (GB)
Title: Enzymes and their use in drug detection
Inventor: BRUCE NEIL CHARLES
IPC: C12N1/20
Filed: 1990-05-11
Abstract: Two enzymes, one an acetylmorphine carboxyesterase (AMCE), the other a morphine dehydrogenase (MDH), have been isolated from bacteria. The AMCE degrades heroin to morphine and the MDH oxidises morphine to morphinone, with the aid of a cofactor. These reactions are used in detection of heroin (using the two reactions coupled together) or morphine. The enzymes can be incorporated in sensors for this purpose.

Title: Elastomeric seating member.
Inventor: ADAMS GRAHAM LEONHARD
IPC: B60R16/023
Filed: 1990-11-17
Abstract: This invention relates to elastomeric seating members and an assembly incorporating the same particularly for solenoid coils of solenoid valves in ABS systems. The elastomeric seal (40) in accordance with the invention provides a moisture resistant seal between a first housing (24) in which first members such as the solenoid coils (26) are mounted and a second housing (48) in which electronic means such as the electronic control circuitry (38) for the solenoid valves is mounted. The elastomeric seating member is mounted within a bore (32, 32a) communicating between the first and second housings and provides a seat for the solenoid coils and is arranged to permit the solenoid coils a limited amount of movement so that when the first housing is mounted on a valve block (20) comprising switch parts (30) of the solenoid valve, the elastomeric seating member permits the movement of the solenoids for alignement with the switch parts (30). The solenoid coils are coupled to the electronic circuitry in the second housing by way of wires (34) which extend from the solenoid coils through a bore (50) in the elastomeric seating member. The wires are electrically coupled to contacts on integral flexible finger portions (46) of a circuit board containing the electronic circuitry.

Title: Microfiltration membranes from aromatic polyamides
Inventor: HESE NILS
IPC: B01D67/00
Filed: 1991-01-22
Abstract: There is disclosed a process for the manufacture of microfiltration membranes from aromatic polyamides, of which the pore sizes are between 0.05 and 10  mu m. A copolymer of isophthalic acid and m-phenylenediamine is dissolved in a solvent mixture of dimethylacetamide and dimethylformamide in the presence of alkali or alkaline earth chlorides and polyethyleneglycol. This solution is produced without the addition of water and is subsequently poured out onto a smooth surface formed of chemically inert material with the formation of the membranes. The water required as the precipitation agent is only added to the poured out solution by means of the air humidity. The relative air humidity is increased from 30 to 100% during formation of the membranes.

Title: Pressure sensor
Inventor: KAISER HARRY
IPC: G01L9/04
Filed: 1991-02-19
Abstract: In a pressure sensor (11), the bottom part (13) consists of a baseplate rim (18) and a body (17), which are connected to one another with the aid of an elastic web (19) or web portions. If the bottom part (13) is mounted on a component, thanks to the elastic web (19) no mechanical stresses generating an undefined prestressing of a diaphragm (26) formed in the body (17) or of strain gauges thereon are produced during the mounting. As a result, measurement errors based on mechanical distortion due to the installation can be avoided. <IMAGE>

Title: A crusher
Inventor: HUTCHINSON RAYMOND WILLIAM
IPC: B30B9/30
Filed: 1992-06-16
Abstract: A crusher, eg a car bodyshell crusher, has a base table 11 with a pivotal arrangement 12 at one or both ends. The movement applied by power rams 15 is transferred by this pivotal arrangement to crushing plates 16. The pivotal arrangement does not extend significantly beyond the perimeter of the base plate, and therefore the size of the crusher is minimised for easy transport. The crusher may be provided with side crushing plates 20. In use, the crushing pads 16 are raised and the side crushing plates 20 are withdrawn. The object to be crushed is placed on the base table 11. The power rams 15 are operated and the movement is transferred by the pivotal arrangement 12 to the crushing pads 18 which crush the object. The side plates 20 are then extended by power rams to further crush the object from the sides. <IMAGE>

Title: Torsional vibration damper
Inventor: VOLLETT ERIC MALCOLM
IPC: F16F15/16
Filed: 1992-11-23
Abstract: A torsional vibration damper comprises a rotary body with an inner member 2 and an outer member 3 overlapping radially to define at least one pair of variable-width axial gaps 19, 20. An annular chamber 21 in one of the members is divided into variable-volume compartments 22, 23 by at least one annular spring 24. Constricted conduit means (27, 29, 31, 32) for damping fluid interconnect the axial gaps with respective compartments (22, 23).

Title: Compressed gas bottle
Inventor: SKANBERG TORBJORN
IPC: B60R21/26
Filed: 1993-05-12
Abstract: A gas generator comprises a bottle (1) defining a volume (2) containing compressed gas. A housing (4) within the bottle contains a movable element (18). In an initial position the movable element lies adjacent at least one aperture (42) formed in the housing (4), that aperture initially being sealed by a sealing disc (43). The or each sealing disc (43) is initially supported by the movable element (18) and is held in position by compressed gas within the space (2). When the movable element (18) moves in response to activation of a triggering mechanism (10), the movable element (18) no longer supports the or each sealing disc (43) which then moves to a position in which it no longer closes the aperture (42) thus creating a flow path for gas from the space (2) to a reaction zone (15). <IMAGE>

Title: Energy regulators
Inventor: TAYLOR JOHN CRAWSHAW
IPC: H01H37/20
Filed: 1993-05-12
Abstract: An energy regulator having a set of switch contacts 14, 16 which in use control the flow of electric current to a load has a snap-acting switch contact arm 18 which is operated by a bimetallic actuator 9 and has an electric heater 60 which heats the bimetallic actuator 9 when current flows to the load. The bimetallic actuator is thereby caused to flex and in so doing opens the switch contacts. The cycle then recommences. The cycle-length is adjusted by means of a control knob attached to a plastics spindle 4 which is integral with a cam body 6 which in turn is used to adjust the operation of the bimetallic actuator 9. The cam body and spindle are partly hollow and the regulator has a housing with an upstanding pillar 10 over which the cam body 6 and spindle 4 engage. The housing is formed by two mouldings which are snap fitted together and which cooperate to locate components of the regulator. An actuator (314, Fig 7) may extend through the spindle 4 for actuating a further switch. The cam body 6 has upper and lower cam track surfaces associated with respective contact sets and an edge surface engaging a detent spring (218, Fig 4). A terminal of the regulator comprises a folded spade portion (402, Fig 9) and a spring tongue (404) for preventing withdrawal of the terminal from the housing. <IMAGE>

IPC: H01H13/705
Filed: 1993-07-20
Abstract: A key switch assembly has a key pad formed from a plurality of individual keys (15) arranged in rows and columns. A first elastomeric sheet (13) has a plurality of holes corresponding to positions of keys in the key pad. Each hole stretches around a corresponding one of the keys in order to provide an environmental seal. A second and unbroken elastomeric sheet (16) stretches under the keys to provide a second environmental seal. The keys when pressed cause a pair of switch contacts on a board (18) to be bridged. When the key is released the elastomeric sheets provide a return force to restore the key to normal. The key switch assembly is sealed against ingress of fluids and debris. <IMAGE>

Title: Preventing interlayer shorting in a magnetic alloy laminate
Inventor: ARTUS DAVID EUGENE
IPC: B32B7/12
Filed: 1993-09-14
Abstract: A bond layer (12) between two layers (11, 11) of uncoated, magnetic alloy strips comprises a particulate filler (13) having an average particle size sufficient to prevent interlayer shorting of the magnetic alloy strip. Methods of making a stack of laminates for use in a transformer, stator or rotor are described. The preferred particulate filler is a hollow thick-walled silica-alumina alloy spheroid of mean size from 0.5 to 8 microns and the average thickness of the bond layer is from 3 to 25 microns. A composition useful for binding electrical laminates is formed by an epoxy adhesive and a hollow thick-walled silica-alumina alloy spheroid. Minimising the thickness of the layer between magnetic alloy strips is said to improve efficiency and reduce performance variations between units. <IMAGE>
