Title: Bit-focused multiplier
Inventor: TIBAZARWA AUGUSTINE KAMUGISHA
IPC: G06F7/52
Filed: 1994-06-01
Abstract: Two numbers, A and B, can be muitiplied together to give a third number Z, such that, if numbers A, B and Z are considered in their binary forms, it becomes possible to use Boolean algebra to express the value of each binary digit of Z independently of the other digits of Z by using only binary digits of A and B. Because of the ease of converting Boolean logic into hardware logic components, these expressions, which focus on the individual binary digits of Z, become the basis for implementing a fast multiplier in hardware.

IPC: B28B7/00
Filed: 1994-11-02
Abstract: An extruded roof tile 30 has an upper surface 11, which is contoured to give the appearance of a profiled tile and which is, for example provided by projections 30, 34 extending between the upper and lower edges 13 and 14a respectively of the tile, and an under surface having a shape which is other than a contoured shape which generally follows that of the upper surface 11 of the tile 30.

Abstract: A method of operating a computer system, in particular a micro-computer having a storage device shared between several application programs, comprises a backup process including a process for maintaining a record 30 of changes sought to the data on the storage device whilst the backup process is executing. The record is used to ensure that the data 24 seen by the backup process does not change while it is executing, whilst allowing other processes to continue to update the storage device normally thereby avoiding delays associated with file locking techniques. The additional operations are executed at the level of the operating system interface of the microcomputer in such a manner that normal use of the computer is unaffected, and involve intercepting write operations, 20. <IMAGE>

Patent GB-2316524-A (GB)
Title: Teaching aid
Inventor: GOUGH SEYMOUR JAMES KEITH
IPC: G09B19/00
Filed: 1996-08-16
Abstract: An interactive teaching aid whereby children are presented with a number of both dangerous and safe scenarios comprises a plurality of such scenarios, means to present one to a child, and means enabling the child to predict one of a number of outcomes for the scenario, with means to monitor the correctness of this response. The scenarios may be stored on a computer disc, and may be presented to the child in the form of an animated video sequence. Alternatively, the scenarios may be stored in printed form, in a book or on playing cards. The teaching aid may be used with a board (52, Figure 2) wherein the child advances around the board as each correct prediction is made. The child learns to differentiate between safe and dangerous simulated real life situations - such as abduction - by predicting the most likely outcome. A timer may be used to determine how long the child takes to make prediction. The sooner in the presentation the child correctly makes a prediction the higher the score. Explanations are given when an incorrect prediction is made. The purpose is to allow the child a chance to learn when it is necessary to escape from a situation and to recognise the danger signs early enough to do so.

Title: A synchromesh gear shift assembly having gear wheel and shift wheel coupled with lost motion
Inventor: LUDANEK HARALD
IPC: F16D11/14
Filed: 1997-01-31
Abstract: A synchromesh gear shift assembly 10 comprises a gear wheel 16 coupled to a shift wheel 18 via drivers 22 and springs 26, thereby providing lost motion which allows shift teeth 20 to move relative to gear wheel 16 so as to evade a sliding sleeve's shift teeth (30, fig 5) when they are located opposite each other. This construction prevents jamming and/or rattling each of which may result in wear. After engagement of the shift teeth the sliding sleeve transmits torque to the shift wheel 18 which then bears with its drivers 22 on end walls/flanks of recesses 24 and thus applies the torque to gear wheel 16. At the same time, a trapezoidal undercut on the driver 22 and recess 24 prevents the shift wheel 18 from escaping axially. For damping purposes, the flanks of the recess is lined with insulating strips 28 of elastics material. In another embodiment (see fig 6) each recess 24 is made deeper with converging flanks (34, fig 6)and an additional spring (32, fig 6) is provided which returns wheel 18 to its normal position (as shown in fig 6). The assembly allows rapid synchronization and rapid positive locking.

Title: An emitter-coupled VCO with constant output amplitude
Inventor: TCHAMOV NIKOLAY
IPC: H03K3/282
Filed: 1997-05-08
Abstract: In an emitter-coupled VCO, transistors Q5,Q6,Q7, and Q8 alternately connect current sources 21 and 22 to the emitter nodes in dependence on the state of the main transistors Q1, Q2. The sum of the currents produced by the current sources is constant (figure 3), so that while the current Icon flowing through the capacitor C may be varied to control the frequency, the amplitude of the current flowing through the main transistors Q1,Q2 and the load resistors RC1, RC2, is constant. Diode-connected transistors Q9-Q12 prevent saturation of transistors Q7 and Q8. The operating voltage is approximately 4.5 volts, and the frequency may be in the GHz range. The circuit may be implemented using MOS, HEMT, or HBT transistors, or may use valves.

Abstract: A passive transponder tracking device 4 is glued in place on to a computer memory board 2. Memory chips 3 and the tracking device 4 are then protected by a cover 5 which is glued down on to the top surface of the chips 3. If an attempt is made to remove the cover 5 the chips 3 will be ripped off the board 2 because the chips are fixed to the cover 5 by the layer of glue 7 and the chip leads 8 will be damaged. If the memory board is stolen and subsequently recovered a scanner can be used to read the individual code set into the tracking device 4 and, by means of a register, the ownership of the memory board can be traced.
