Title: Data transmission systems
Inventor: HODGKISS WILLIAM
IPC: H04L27/01
Filed: 1987-03-13
Abstract: A modem for a digital data transmission system in which binary- coded data at up to 9.6 Kbit/sec is transmitted over a telephone line pair circuit, as phase and amplitude modulation (QAM) of a carrier signal at a frequency of 1800 Hz, at a line symbol rate of 2400 baud/s. The modem utilises two data signal processors (4 and 5) and two gate arrays (6 and 7), controlled by a microprocessor, to carry out digitally all the processes required to convert binary coded data signals into PCM coded samples of the required carrier signal for transmission, and to recover binary coded data signals from PCM coded samples of a received carrier signal. On the reception side received signals are sampled, pulse coded and fed to a transversal filter to produce digital carrier wave samples at time intervals determined by the received signal components. <IMAGE>

Patent GB-2210096-A (GB)
Title: Press-button locking fastener
Inventor: SHENTON NIGEL PHILIP
IPC: E05B13/10
Filed: 1987-09-24
Abstract: An operating handle 1 of a window or door fastener incorporates a key-operated push-button locking mechanism comprising a spring-loaded barrel 3 axially movable within a cylindrical bore 16 in the handle 1 extending parallel to a pivot axis of the handle. In the locked position when the barrel 3 is pushed inwards. an arm of a leaf spring detent latching element 7, housed in a slot 19 in the handle, engages in a circumferentially extending recess 17 in the barrel 3 at the inner end of a keyway 15. In the unlocking operation a key 5 engages the leaf spring arm and moves it out of latching engagement with recess 17 after turning through an angle of about 45 DEG . This enables the barrel 3 to move axially outwards into a retracted unlocked position. At the same time, the barrel 3 is rotated back to its original angular orientation by co-operation between a positioning lug 3b with a tapering guide groove 11. Relocking is carried out by simply pushing the plug or barrel 3 axially inwards without any change or angular orientation. This design of mechanism avoids use of a cylinder lock with conventional tumbler mechanism. <IMAGE>

IPC: G01P15/125
Filed: 1987-10-31
Abstract: A normally sealed container, which may be transparent, contains a liquid and a gas or two different liquids which move upon the container being tilted or accelerated sideways. The movement of the liquid, which is normally mercury, may be visually detected and measured or it may be electrically indicated by means of contacts or surrounding plates or coils that will allow the relative angle of the liquid surface or interface to the container to be displayed upon an electrical meter or will allow electrical devices to be operated at specific values of tilt and/or acceleration, e.g. to operate an alarm or shut down the power in a vehicle or plant. The rate of movement of the liquid and/or gas may be controlled and/or damped by one or more internal fixed or variable orifices. The container may be toroidal, or comprise two orthogonal toroids with a common fuse interconnection, or the liquid space may be defined between concentic spheres. <IMAGE>

Title: Manufacturing a porous electroformed object
Inventor: TAZAKI YUICHI
IPC: C25D1/00
Filed: 1988-07-11
Abstract: An electrically conductive layer is formed on a surface of a model (20), and an organic solvent layer of an organic solvent which is inactive with respect to the conductive layer is formed on a surface of the conductive layer. Particles (40) are then placed on the organic solvent layer to allow the particles to be partly melted by the organic solvent layer, and the organic solvent layer is removed to allow the particles to be adhered to the conductive layer. A metal layer (36) is deposited on the model (20) in an electroforming process to form an electroformed shell thinner than the diameter of the particles. The electroformed shell is separated from the model, and the particles are dissolved away from the electroformed shell with an organic solvent to produce an electroformed object having a number of vent apertures. Unlike prior art processes, the invention allows porous electroformed objects to be made without the need to drill or laser machine the electroform to form the poses. The electroformed object may be a mold used for vacuum forming synthetic rain components of automobiles e.g. console boxes. <IMAGE>

Title: Apparatus to be used when welding pipes together
Inventor: SUNDHOLM GOERAN
IPC: B23K37/04
Filed: 1988-09-16
Abstract: PCT No. PCT/FI87/00042 Sec. 371 Date Sep. 16, 1987 Sec. 102(e) Date Sep. 16, 1987 PCT Filed Mar. 24, 1987 PCT Pub. No. WO87/05844 PCT Pub. Date Oct. 8, 1987.The invention relates to an apparatus to be used when welding pipes together. The apparatus comprises a bellows structure (4, 5) for shielding the weld joint area by internal contact with the pipe ends on both sides of the weld joint (3). When the apparatus is inserted and, especially, pulled out after welding, the bellows tend to be damaged by the hot weld joint. It is the object of the invention to solve this problem. The object is achieved by providing both bellows (4, 5) with radial side supports (14, 15) dragging against the inner surface of the pipes and by arranging the bellows to contract within the radial side supports in the absence of an inner overpressure. Between the bellows (4, 5), centering discs (9, 10) are arranged on hoses (6, 7, 8) for leading a protective gas and compressed air. The hoses (6, 7, 8) are connected with the holders of the bellows by means of a through cotter pin provided with a spring (17) for keeping the pin stationary.

Title: Optical system for monitoring movement in utility meters
Inventor: WILKS A J
IPC: G01D4/00
Filed: 1989-02-17
Abstract: A simple optical system for monitoring movement of a needle in a utility meter has an adaptive feedback loop which automatically adjusts for static optical conditions, hence dispensing with the requirement for precision opto-mechanical adjustment. Light from a source (3) is reflected by the meter dial to a photoresistive detector (5). The current (i1) through the detector (5), which is balanced by current (i2) in the static condition, is fed to an amplifier (8) and integrating feedback circuit (10 to 14) which overcomes drift and maintains a zero output in the static condition. Passage of the meter needle throught the light produces a large output which is fed to a comparator (15). <IMAGE>

Title: A pipe repair or connection clamp
Inventor: DERBYSHIRE FRANCIS
IPC: F16L21/00
Filed: 1989-03-17
Abstract: A pipe repair or connection clamp comprising a non-continuous band (11) of stainless steel surrounding a resilient sealing gasket (17), with a bridge plate (18) bridging the gap between the ends of the band (11). The adjacent ends of the band are attached to respective lugs (13) which are drawn together by bolts (14). The invention provides either a support plate (20) in the form of a stainless steel strip bent in a zig-zag shape or a pair of relatively slidable wedges located between the bridge plate (18) and the bolt (14). As the lugs (13) close together during tightening of the clamp; the support plate (20) or wedges may expand axially but remain to support the bridge plate (18) and prevent it from being "extruded" into the gap. <IMAGE>

Title: Ameliorating the odour of liquid fuel
Inventor: SALOOJA KAILASH CHANDER
IPC: A61L9/12
Filed: 1989-04-07
Abstract: The perceived odour of liquid fuel (particularly, but not exclusively, diesel fuel) is ameliorated by disposing an odour- ameliorating or -modifying substance in the vicinity of fuel dispensing equipment at least during the period when fuel is dispensed from the equipment, preferably so as to be exposed to the environment and preferably so as to be not normally contactable by a human operator. In one embodiment, the substance is incorporated in strips 15, 16 adhered around the supply and dispensing pipes 12, 11 of fuel dispensing equipment 10. Alternatively or in addition, the substance may be incorporated in strips which are received in grooves 17, 18 in those faces of the operating lover 13 and/or lever guard 14 which are not normally handled during use of the nozzle. The strips 15, 16 may each comprise a porous substrate on which the odour-ameliorating substance is impregnated and which is encapsulated in a porous plastics or textile sheath to regulate the rate of release of the odour-ameliorating substance. <IMAGE>
