Title: Apparatus for generating a signal for driving the field deflection in a picture reproducing device
Inventor: DECRAEMER ALAIN
IPC: H04N3/16
Filed: 1983-10-24
Abstract: In a picture display device with a digital time base and providing an indirect field synchronisation by means of counting the number of half line periods and ascertaining if for a certain number of times there has been coincidence between the appearance of a predetermined count and a received field pulse, the detection of coincidence between the appearance of a further count and the said received pulse enables operation with indirect synchronization for two different standards e.g. 625-line and 525-line standards. The synchronizing circuit comprises one single counter 15, two state detectors (22A, 22B) which detect said coincidence states, and a selection circuit (23) which checks whether the coincidence state has been obtained for one of the two counts and, if so, instructs the reset- to-zero circuit 20 to generate a counting pulse for this count and to utilise it to release the field signal. The circuit 23 also checks whether the coincidence state has been obtained for the two counts or whether it has not been obtained for any of the counts, and in both cases instructs circuit 20 to utilise the separated pulse to release the field signal for the vertical deflection. <IMAGE>

Title: Anti-wheel slip arrangement
Inventor: WORRALL HARRY EDWIN
IPC: B60K28/16
Filed: 1984-05-05
Abstract: To prevent or at least reduce wheel slip at high engine torques, the angular velocity of each driven wheel is monitored, and when the change in angular velocity acceleration rises above a predetermined value, the engine torque is reduced to avoid a condition where slip might occur. Once the change in angular velocity value drops, the restraint on engine torque is removed. A microprocessor 18 is used to evaluate the output of wheel sensor 16 and control engine 14 accordingly. <IMAGE>

Depression of switch button 11 enables operation of actuator 6 in an extension or first mode. Cancellation of depression of switch button 11 enables actuator 6 to undergo corresponding reverse operation thereof so as to return actuator 6 to the condition just before start of said first mode thereof. Depression of switch button 12 will enable operation of actuator 6 in a retraction or second mode. Cancellation of depression of switch button 12 enables actuator 6 to undergo corresponding reverse operation thereof so as to return actuator 6 to the condition just before start of said second mode thereof. The condition of actuator 6 just before start of its first or second mode corresponds to a neutral or parked position of hand control lever 2. <IMAGE>

Title: Welding jig
Inventor: PHELPS MICHAEL THOMAS
IPC: B23K37/04
Filed: 1985-05-23
Abstract: In welding a hollow aerofoil shaped vane 10 to an end piece 12 using a gas-shielded arc-welding technique it is usually necessary to supply inert gas into the hollow vane. If there is any dimensional mismatch between the two items then the inert gas will escape thereby reducing the quality of weld. A jig is provided which is attached to the end piece during welding. The jig comprises a plate 18 with holding tangs and a deformable sealing portion 24 which abuts against part of the joint between the two items thereby at least partially preventing gas leakage. <IMAGE>

Title: Catheter exchange method and means therefor
Inventor: GAMBALE RICHARD A
IPC: A61M25/00
Filed: 1986-06-30
Abstract: A guide wire system for use in catheter exchanges avoids the need for a separate exchange wire. Instead of the conventional practice in which the initial guide wire is removed and replaced with a longer exchange wire, a guide wire extension is attached to the proximal end of the initial guide wire thereby increasing its effective length so that it may be used to perform a catheter exchange. The initial guide wire remains in place in the patient's vasculature. The proximal end of the guide wire and the distal end of the exchange wire are formed to define a connection which may be crimped to effect the connection between the two wires. A crimping tool is provided to hold the mating ends of the guide wire and extension wire together while effecting the crimp. <IMAGE>

Patent GB-2198275-A (GB)
Title: Notice board
Inventor: BISCHOFF HERMANN-JOSEPH
IPC: G09F7/02
Filed: 1987-05-14
Abstract: A notice board has a body (1), and rotatably mounted on this body (1), a plurality of appropriately arranged segments (2). These segments (2), have faces of different colours, such that one face may be the same colour as the body (1), whilst the other face is of a colour that contrasts to that of the body (1). Rotation of a segment (2) thereby allows the selective presentation of either face, depending on whether that segment (2) is to present a visual contrast to, or to merge with the body (1) of the board. The body (1) and its segments (2) are preferably mounted on a supporting board (4) via an upper hinge (5) and a lower magnet (6) or other attachment. By appropriate positioning of the segments on the bodies and the visual presentation of these segments, (and possibly by having several such bodies and corresponding segments) the formation of selected groups of letters, numbers and other data is possible. <IMAGE>

Filed: 1988-01-19
Abstract: A card reader (2) for reading e.g. a "smart card" (1) having contact pads (7a,7b) thereon which are connected to an information store such as an integrated circuit. The card reader includes an enclosed sliding carriage (4) with wedge-shaped cams (9a,9b) that urge leaf contacts (6a,6b) into engagement with the contact pads (7a,7b) on the card (2) when it is inserted into the card reader. A microswitch, operated by the card, supplies power to circuitry for enabling the card to be read. The card reader can be made very slim, e.g. 5mm. Also, since the leaf contacts do not engage the card except when the card is fully inserted there is no wear on the card or the leaf contacts during insertion or withdrawal.

Title: Method of determining the tap weights of a decision feedback equaliser
Inventor: NEWTON DAVID JOHN
IPC: H04L25/03
Filed: 1988-12-08
Abstract: A decision feedback equaliser DFE comprises a feedforward filter section 10 and a feedback filter section 12 including a decision stage 14. Each of the filter sections includes a transversal filter, the tap weights of which are calculated to overcome the dispersive effects of a communications channel on the received signal. A known method of calculating the tap weights recursively comprises  w=R<-1>p where R is the autocorrelation matrix describing the DFE, p is the cross correlation vector of the desired and received samples and w is the vector of the equaliser tap weights. In order to avoid the problem of matrix inversion and to permit the calculations to be done directly in a single operation with a reduced amount of computation and storage requirements the above equation is restated as Rw = p and the autocorrelation matrix R is factorised using Gaussian elimination techniques into upper (U) and lower (L) triangular matrices. Thus ULw = p (or LUw = p). This equation is solved in two stages; (1) Solve Uc = p (or LC = p) where c is the unknown and (2) solve Lw = c (or Uw = c). As the triangular matrices are expressed in terms of the channel impulse response samples, then many of the terms can be entered, without computation, on the basis of an estimate of the channel impulse response. <IMAGE>

Title: Accessing a page mode memory in a computer system
Inventor: BLAND PATRICK MAURICE
IPC: G06F13/36
Filed: 1989-03-03
Abstract: A computer system includes a page memory in which a row address accompanied by a row address strobe (RAS) is followed by a column address accompanied by a column address strobe (CAS) to read data from a memory location during a memory cycle. When, in a following memory cycle, a further location from the same page is to be accessed, the row address and the RAS remain constant and a new column address is used with the CAS being precharged by switching it to its OFF state and then returning it to its ON state. This is normally done at the start of the following memory cycle. In the present system, the data is read and latched shortly after arrival of the column address and CAS in the first of the memory cycles so that the CAS recharge can take place at the end of the first memory cycle and before the start of the following memory cycle.
