Patent GB-2220771-A (GB)
Title: Integrating circuit
Inventor: WEBBER CHRISTOPHER
IPC: G06N3/063
Filed: 1988-07-15
Abstract: An integrating circuit comprises analogue integrating means 20 (Fig. 2) for receiving an input signal, digital counting means 36 and means for altering a value stored in the digital counting means according to the polarity of a signal received from the integrating means whenever the magnitude of the signal from the integrating means reaches a predetermined threshold, set by Schmitt triggers 32, 34. Thus the count valve represents an integrated value of the input signal (Fig. 4). A d/a converter 38 provides an analogue output. The effects of feedback capacitor leakage are thus much reduced. A logarithmic circuit may be provided by use of non-linearity in the d/a converter 38. The application is to neural networks. <IMAGE>

Abstract: PCT No. PCT/GB88/00294 Sec. 371 Date Oct. 13, 1989 Sec. 102(e) Date Oct. 13, 1989 PCT Filed Apr. 15, 1988 PCT Pub. No. WO88/07907 PCT Pub. Date Oct. 20, 1988.Deposition of a first relatively hard material on a second material that is relatively soft using a rotating rod, bar, tube or other body without translation of the rotating body relative to a workpiece of the second material is achieved by positively cooling the interface between the body and the workpiece such that a shear layer at which heat is being generated moves away from the surface in the direction of the rotating body. On removal of the rotating body from contact with the workpiece, the workpiece is found to be surfaced with material from the rotating body. In a second stage the already deposited material from the rotating body may be cooled by a surrounding body of liquid to enable further material from the rotating body to be deposited on the workpiece. The workpiece may be of plain carbon steel and the rotating body may be of high speed steel or a nickel-based alloy.

Title: A tube connector
Inventor: PARDY RONALD
IPC: F16L37/098
Filed: 1990-10-24
Abstract: A tube connector has a cylindrical body 26 into which a tube 14 with a shoulder 20 can be inserted to form a locked, fluid-tight joint. The tube 14 is first inserted into a collar 32 which provides the locking function, and the collar and the tube are then slid further into a cylindrical body portion 26 until the end of the tube is sealed against O-rings 28.

Title: Cable stripping tool
Inventor: CARR JOHN HENRY
IPC: H02G1/12
Filed: 1990-11-15
Abstract: A hand tool for splitting the sheath of a cable includes a handle formed from a body 11/12, with twin blades 19/25, therein. The blades slit the cable sheath on opposite sides as the tool is moved relative to the cable so as to expose the conductors and the rip cord. This cord can be held in the tool to assist with further slitting e.g. at notches 28. The ribs 16, 17 prevent sideways movement of the handles when cutting. Adjacent the blades the channel 15 is wider to allow room to split the sheath. The body is provided with stepped portions 11a, 12a to assist gripping. In another embodiment (Figs 8 to 11) indentations (41) in the body assist gripping and the blades (46, 47) are held by screws (52, 52). Replacement blades may be held in the tool. <IMAGE>

Patent GB-2261482-A (GB)
Title: Rod tensioning
Inventor: SCOTT PETER ANDREW JAMES
IPC: B25B25/00
Filed: 1991-11-12
Abstract: A rod (R) e.g. of composite material, is tensioned using an apparatus which comprises a first collet assembly (10), a second collet assembly (12), and force applying means (14) operable to move the first collet assembly (10) away from the second collet assembly (12). The collet assemblies (10, 12) are assembled on the rod (R) and the force applying means (14) is operated. The second collet assembly (12) grips the rod (R) so that the rod is stretched, the first collet assembly (10) allowing this movement. The force applying means (14) is then released allowing the rod (R) to contract slightly. This contraction causes the first collet assembly (10) to grip the rod (R) and hold it under tension. The second collet assembly (12) can then be removed leaving the first collet assembly (10) to hold the rod (R) in tension. If required, the first collet (10) can be released and removed to de-tension the rod (R). <IMAGE>
Patent GB-2250615-A (GB)
Title: Direct memory access controller
Inventor: DRAKO DEAN
IPC: G09G5/393
Filed: 1991-11-18
Abstract: During a block transfer, an address 41 to which information is to be written or from which information is to be read is incremented while a value 43 indicative of a width of a block of data to be transferred and a value 25 indicative of a total amount of information to be transferred is decremented. When the value 43 reaches zero the address 41 is changed by a value 42, which indicates a number of addresses to be bypassed. The value 43 is then reset to its original value. This process continues until the value 25 is reached, i.e. the block transfer is complete. This DMA controller is used to transfer information from a source of television signals to a main memory 13 such that the information is displayed in a window on a display device. The value 43 corresponds to the width of the window and the value 42 corresponds to the portion of the display which lies outside the window in a single scan. Thus the serial pixel output from the source is not stored in the main memory in a block of contiguous addresses and it is possible to minimise processing time involved in displaying the stored frame. <IMAGE>

Title: Methods of joining components
Inventor: LODGE KEVIN J
IPC: B23K1/005
Filed: 1992-09-18
Abstract: This method enables two components (1, 3) to be joined by soldering using heat generated by a laser beam, without the use of flux. A layer (5) of a material which has a lower melting point than the material of one of the components (3) is formed on that component and forms a bond therewith on resolidifying after melting. Solder (7) is interposed between the layer (5) and the other component (1) to form, on resolidification after melting, bonds with the material of the layer (5) and the other component (1). A coating (11) of a further material between the layer (5) and the solder (7) is dispersed when the adjacent layer material becomes molten and is not wetted by the solder (7) when molten. On applying heat to a region (15) of the layer using a laser beam. the layer is melted in this region (15) as is the adjacent solder (7) to form, on resolidification of the solder (7) and molten layer material (15), bonds between the solder (7) and the two components (1, 3). <IMAGE>

Title: Trimming integrated circuits
Inventor: EDDOWES DAVID WILLIAM
IPC: G11C17/16
Filed: 1992-09-18
Abstract: A method for trimming an integrated circuit employs an enhancement mode MOS field effect transistor 8 having its gate connected to its source. As fabricated the source to drain resistance of the transistor is high. A setting voltage, higher than that normally applied to the transistor, can be applied to the drain of the transistor via a terminal 5 to rupture the gate oxide between the drain and the gate so that the source to drain resistance becomes low. The change from high to low resistance of the transistor is used to effect the trimming. A diode or a bipolar transistor 10 may be provided in the connection from the drain of the MOS transistor to the other parts of the circuit in order to block the setting voltage and prevent it from damaging those other parts. <IMAGE>
