Title: Circuit for producing an error numeric value polynomial and an error locator polynomial.
Inventor: NAKAMURA MASARU
IPC: G06F7/72
Filed: 1994-01-27
Abstract: In an arithmetic circuit for producing an error numeric value polynomial and an error locator polynomial in accordance with Euclid's algorithm, a first section (11) produces a quotient polynomial and a remainder polynomial which are obtained by dividing a first polynomial by a second polynomial. The remainder polynomial represents the error numeric value polynomial. A second section (54) is supplied with the quotient polynomial and a third polynomial and produces a multiplication polynomial by multiplying the quotient polynomial and the third polynomial. A subtracting section is supplied with the multiplication polynomial and a fourth polynomial and subtracts the fourth polynomial from the multiplication polynomial to produce a subtraction polynomial. The subtraction polynomial represents the error locator polynomial. <IMAGE>

Title: Programmable self-mobile building materials and their use
Inventor: MICHAEL JOSEPH
IPC: B25J9/10
Filed: 1994-03-04
Abstract: Programmable self-mobile building material is a collection of substantially cubic shaped bricks called monomers that move relative to each other under computer control to sculpt e.g. engineering structures 5 and mechanisms 6 (walking machine) illustrated in Figure 2. The monomers have features to lock to other monomers and slide relative to other monomers without separating. The monomers are fault tolerant against damage; functional monomers move faulty monomers and replace them with functioning clones. Movement of monomers is broken down systematically into streamers, gateways, highways and reservoir methods to obtain individual monomer movement paths required to synthesise a structure. Specialised monomers can carry tools which together with synthesis of custom structures create custom machines. Exemplified uses are (1) self-build walls in a dangerous environment such as a nuclear power station or (2) self-build temporary bridges. <IMAGE>

Title: Determining optimal bias voltages in amplifying circuit
Inventor: FRERICHS BERNHARD
IPC: H03F1/02
Filed: 1995-05-25
Abstract: In an amplifying circuit (10), an amplifier (11) has an input, an output and a direct current supply. A current sensing arrangement measures direct current supplied to the amplifier, and provides a signal, representative of the direct current supplied, to an analog-to-digital converter (38) coupled to the processor (40). The processor outputs a bias voltage control signal from a digital-to-analog converter (42) to control the bias voltage at the input (24) of the amplifier. A factory or field system for a radio is disclosed in which the current supplied to the radio is externally monitored and the information supplied to the radio where internal processing determines the bias level.

Patent GB-2323016-A (GB)
Title: Safety belt pre-tensioner
Inventor: GROS CHRISTOPHE
IPC: B60R22/46
Filed: 1997-03-10
Abstract: In a safety belt pre-tensioner, a pyrotechnic charge (9) generates gas to drive a plurality of balls (11) along a conduit (10) and into a circular recess (13) where they engage an arm (17) on a gear wheel (14). On actuation of the pyrotechnic charge (9) the balls (11) cause the gear wheel (14) to rotate so that the toothed portion (15) engages a smaller gear (19) having a mechanical advantage. The smaller gear (19) is connected to the spindle of a retractor to cause a safety belt mounted on the spindle to be pre-tensioned. The end region of the toothed portion (15) that initially engages the smaller gear (19) may be constituted by a flexible arm that extends resiliently from the rest of the gear (14) to assist the synchronisation of the two gear wheels (14, 19) into driving engagement (see figure 5). Instead of the balls (11), a single elongate flexible element may be used.
Patent GB-2312924-A (GB)
Title: Direct-operated, velocity-controlled nozzle valve for a fuel injector
Inventor: MONCELLE MICHAEL E
IPC: F02M51/00
Filed: 1997-04-07
Abstract: The valve comprises a check (36) which is movable in response to high fluid pressure between an open position allowing high pressure fuel communication with an injection orifice (34), and a closed position blocking communication with the orifice. A spring (44) biases the check valve towards the closed position. Actuating means control communication of high pressure fluid so that only the spring (44) is used to retain the check valve (36) in the closed position and only high pressure fluid is used to move the check valve to the open position. To start injection, solenoid 62 is energised which moves valve 60 to open sealing seat 70 of poppet spacer 28, thus allowing communication between high-pressure fuel passage 46 and control passage 78. High pressure thus acts on the check lift piston (42, fig. 2) which lifts the needle check 36 from its seat in the tip 18. Closing of valve 62 ends injection and the closing velocity of the check 36 is determined primarily by the force of the spring 44 so that damage from impact on closing is reduced.

Title: Fan unit with two fans, guide vanes and tapering duct
Inventor: BRYANT DARREN JAMES
IPC: F04D29/42
Filed: 1998-01-15
Abstract: Two centrifugal or mixed-flow fans 10,11 are mounted in series within a housing 12 for driving air through the housing from an inlet to an exhaust, for driving air in a ventilation system. A tapered duct 17 within the housing reduces the gas flow crossectional area from the exhaust of the upstream fan to the inlet 14 of the downstream fan. Several guide vanes 18 extend radially inwards from the tapered duct to reduce rotational flow of air within the duct. The inlet 21 to the guide vanes 18 is angled to improve the exhaust flow from fan 10. The fans are substantially identical and driven independently by substantially identical electrical motors. Only one fan is driven at any time and the non-driven fan windmills due to the air flow thus forced through it. The air flow through the housing is substantially the same whichever fan is driven (fig 7).

Title: Improvements in or relating to apparatus for forming ground engaging supports
Inventor: BULLIVANT ROGER ALFRED
IPC: E02D5/38
Filed: 1998-01-27
Abstract: A pile casing (10) for forming a pile comprises a circular cross-section tubular steel member (11) and an openable assembly (26) at the leading end. The pile casing is driven by vibrating means into the ground to displace earth to form a hole which can be filled with pile forming material as the casing is removed. The tubular member has means (14) for attachment to a vibrator and longitudinally extending apertures (21). The assembly (26) forms a pile tip and has a collar (28) which can be attached to the casing (10). The assembly also comprises four triangular shaped door members (30) hinged at their upper ends (32) to a member (34) fixed to collar (28). In the closed position the unconnected sides (36) of the triangular members form a pyramid tip. Once the casing has been driven to the required depth it is withdrawn from the ground causing the hinged doors to fall into an open position. Pile forming material fed into the casing through apertures (21) at the surface flows down the casing and enters the hole through the now open, hinged doors.
