Patent GB-2221553-A (GB)
Title: Microprocessor bus interface unit
Inventor: SHOEMAKER KENNETH D
IPC: G06F15/78
Filed: 1988-11-28
Abstract: A microprocessor which has an internal data bus width of n bytes where n is greater than 2 (in the currently preferred embodiment, 32-bit bus) provides address signals for an n byte transfer (read or write) of data. An input receives at least one "size" signal 34, 35 which indicates the number of bytes that an external memory will transfer on the next ready signal. The microprocessor includes logic means and an output 29 for providing a "last" signal indicating that a data transfer request by the microprocessor will be satisfied with the data transfer occurring at the next ready signal. This logic means keeps track of the number of bytes that have been transferred, periodically senses the byte sizing signal, and is able to change the status of the "last" signal "on the fly". Therefore, by way of example, the external memory can provide a particular byte size signal as a default condition, and then change the signal when the memory determines the number of bytes that the memory is actually able to transfer. The "last" signal will change accordingly. …<IMAGE>…

Title: Double cone pressure meter
Inventor: CORKE DAVID JULIAN
IPC: G01N33/24
Filed: 1990-04-17
Abstract: A double cone pressuremeter has a body (1) in the shape of two hollow cones placed base to base. As the device is pushed downwards into the ground, the solid nature of the variable diameter fixed body (1) forces the surrounding soil at a particular level to deflect radially outwards and then inwards in a controlled manner and at a predetermined rate in order to force upon the soil the type of deformation required to carry out a pressuremeter test. Strain gauged circular hoops (10) set flush with the outer surface of the device measure the soil pressure. Drilling fluid passes down a pipe (5) and is removed together with soil or rock waste via the annulus between the pipe (5) and body (1). Water pressure is measured by sensors (11). <IMAGE>

Title: Monitoring container filling
Inventor: PERRY STEVE CRAWFORD
IPC: G01G13/14
Filed: 1991-04-05
Abstract: Determining the content weight of a series of filled containers (e.g. beer kegs) comprises: weighing each container empty and providing on it an indication of the one of a number of different weight ranges in which the empty container lies, then weighing each filled container, sensing the indication thereon, and subtracting the maximum empty weight in the range indicated for the container from the weight of the filled container to determine the weight of the container content. The indications of weight ranges used for containers of different nominal weights may be the same, in which case the material of each container may be sensed to determine its nominal weight. In the described arrangements for beer kegs the indication is provided as circular coloured areas, e.g labels or stickers, on one or both ends of the keg, and/or as bands of colour running circumferentially about the keg. <IMAGE>

Title: Denesting stacked articles
Inventor: FLETCHER ALAN JAMES
IPC: B65G59/10
Filed: 1991-04-12
Abstract: An apparatus for automatically denesting polystyrene trays 16 (not shown) with peripheral flanges from a nested stack of such trays comprises a pair of structures 40, each having two component parts which are rotatable together within a housing 10, on opposed sides of a tray cassette above a conveyor. Each component part is profiled to have at least one supporting edge which can project through an opening 32 in a wall 30 of the respective housing below the stack of trays for engagement with the flanges of the trays. The profile of each component part is such that, on rotation, a supporting edge is alternately presented through the housing and then withdrawn into the housing. The supporting edges of the respective component parts are angularly displaced so that when support is removed from a lowermost one of the trays 16, the flange of the next to lowermost one of the trays 16 is simultaneously supported thereby to continue to support the stack. The component part 40 is formed with a cam surface which denests the lowermost unsupported one of the trays 16 onto the conveyor. <IMAGE>

Title: Lockable cover assembly for vehicle audio equipment
Inventor: MCMAHON JAMES KEVIN
IPC: B60R11/00
Filed: 1991-07-04
Abstract: A cage (10) fits into an aperture in a vehicle dashboard to surround the front region of audio equipment which is subsequently fitted therein. A cover or lid (14), which fits over the front of the equipment, to conceal it, is lockable to the cage (10) by a key actuated mechanism comprising a pair of locking members (16) which are displaceable laterally, mutally apart or towards each other under the influence of a rotatable element (20). Engagement means, such as lugs (35), on these members (16) interlock with engagement portions, such as apertures (27), at respective ends, preferably at each corner, of the cage (10). To retain the cage (10) an auxiliary frame (12) may be used which has tabs (13) which are deformable so as to engage behind a relevant portion of the vehicle housing. A two part frame, with tabs formed only on one part, is particularly advantageous and may be used as part of other lockable cover assemblies. <IMAGE>

Title: Ribbon cable insulated by PTFE
Inventor: MCNAUGHTON DAVID
IPC: H01B7/08
Filed: 1991-11-25
Abstract: An electrical ribbon cable comprises a plurality of conductors arranged side-by-side wherein adjacent conductors are insulated from each other by an insulating layer containing PTFE. Adjacent conductors are spaced apart not greater than three times the thickness of the insulation. In one embodiment (Fig 4) conductors (20) with insulation (21) are compressed side-by-side and heated to bond the insulation. Alternatively (Fig 7) uninsulated conductors (50) have a serpentine insulation layer (51) to separate them and insulating layers (52, 53) above and below the conductors. In other embodiments, spaced insulated conductors (60, 61) are thermally bonded to an insulating layer (62 Fig 8), or serpentine insulation (13, 32, 40) is woven between adjacent or every other pair of insulated conductors (Figs 1, 3, 5, & 6) with or without a supporting insulating layer (14, 43). The cable may be made by passing the conductors and layers through laminating rollers (15, 16 Fig 3) and thermally bonding. The cables have the advantage that they withstand high temperatures and are flexible. The cable may be shaped by placing it in a metal mould (Fig 9) and heating it in an hydraulic press. <IMAGE>
