Patent GB-959018-A (GB)
IPC: H03H7/00
Abstract: 959,018. Hall-effect circuits; electro-mechanical transmission devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 21, 1960 [June 24, 1959], No. 21729/60. Headings H3T and H3U. A four-terminal device having unidirectional transmission properties comprises a gyrator 5 and a transformer 10, Fig. 1, one winding of the transformer being arranged in series with one pair of gyrator terminals and the other winding being in parallel with the other pair of gyrator terminals; the parameters of the transformer and gyrator being so chosen with respect to each other that in one direction the signal transmitted through the gyrator cancels that transmitted through the transformer. Fig. 2 shows a simple embodiment employing a Hall-effect device 5 as the gyrator. By reversing the applied magnetic field at right-angles to the plate 5 the preferred direction of transmission may be reversed. In a modification of this arrangement Fig. 4, each pair of electrodes on the Hall plate is replaced by a plurality of pairs, individual pairs being supplied by respective windings of transformers 47 or 10; the transformer 10 also provides the transformer coupling around the gyrator as in Figs. 1 and 2. In Fig. 5 the Hall plate 5 is replaced by a semi-conductor cylinder 19 to which a radial magnetic field is applied. Areas 61 to 66 and 71 to 76 constitute one set of pairs of terminals, viz. those supplied from transformer 47, by considering the plate 5 of Fig. 4 wrapped to form the cylinder 19, it can be seen that the other set of pairs of terminals is replaced by an infinite number of conducting loops arranged horizontally around the cylinder, these being coupled to winding 12a and thence to winding 11<SP>a</SP> effectively equivalent to the transformer 10. In a further embodiment, Fig. 6, 1 and 2 represent the outer and inner conductors respectively of a coaxial cable. The outer conductor 1 is slotted as shown, the left-hand end of the slotted portion having a circumferential component which provides electromagnetic coupling between the current flowing in the cable and a winding 12a. A semi-conductor cylinder 19 is inserted over a portion of the length of the outer cable and a magnetic field is arranged to pass radially through it. The conductors joining the left-hand end of the cylinder 19 with corresponding parts of the inner conductor 2 are of spiral form so as to increase the electromagnetic coupling with the winding 12<SP>a</SP>. The cylinder 19 thus operates as a gyrator as in the arrangement of Fig. 5 while the electromagnetic coupling to the winding 12<SP>a</SP> effects the transformer coupling around the gyrator. In a second embodiment employing slotted coaxial lines, Fig. 7 (not shown), the Hall plate is in the form of a disc arranged perpendicular to the axis of the line, the magnetic field then being directed axially. Electromechanical devices. A magnetostrictive rod coupled mechanically to a piezoelectric crystal, Fig. 3 (not shown), may be made to serve as the gyrator. Specifications 953,334 and 959,017 are referred to.

Title: Interfacing to SAR devices in ATM switching apparatus
Inventor: O'NEILL DOMINIC CHRISTOPHER
IPC: H04L12/56
Filed: 1997-04-23
Abstract: A switching apparatus, for use in an ATM network, includes a switch fabric 8 for switching ATM cells, a segmentation-and-reassembly (SAR) device 12 for reassembling packets from ATM cells, and a plurality of traffic management (TM) devices 241-24N. Each TM device 24 receives ATM cells delivered to associated ports of the apparatus and is connected by a first data delivery path 10 to the switch fabric and by a second data delivery path 26 directly to the SAR device 12. The TM device identifies those received ATM cells that belong to one or more predetermined types of packets requiring reassembly by the SAR device, and delivers these to the SAR device 12 via the second data delivery path 26 for reassembly into packets. Cells not requiring reassembly are delivered to the switch fabric 8 via the first data delivery path 10 for switching by the switch fabric. This means that reassembly cells do not pass through the switching fabric in the course of transfer from the TM device to SAR device. This increases the switching fabric's capacity to switch other data. In Figure 11 (not shown) the SAR device is part of, or is replaced by, an internet-protocol (IP) switch controller used to detect IP flows through the switching apparatus.

Title: Hydraulic brake locking device
Inventor: ROBERTS ALAN PHILLIP
IPC: B60R25/08
Filed: 1998-02-27
Abstract: A hydraulic brake locking device for a motorcycle comprises a body 1 provided with a passage for flow of brake fluid from an inlet 4 to an outlet 3, a locking screw 5 for closing the passage, and a by-pass 9 containing a one-way valve 8 which permits flow of brake fluid from the inlet to the outlet when the passage is closed by the screw. The locking screw 5 seals the pressure in a brake caliper, thus holding the brakes tightly on, and preventing theft of the motorcycle. It also stops parts thieves from removing wheels, as due to the 'grip' of the brakes on the discs, the wheels are immoveable. The device is controlled by a security key which is removed after either setting or releasing the pressure. Due to its construction, the device cannot be removed and replaced without access to workshop tools or disabling the entire braking system. This latter fact alone will be a deterrent against theft.

Title: Accumulator (common rail) fuel injection system for vehicle diesel engines
Inventor: NARAHARA YOSHIHIRO
IPC: F02D41/06
Filed: 1998-12-10
Abstract: An accumulator fuel injection system comprises a common rail 3 pressurised by a high pressure pump 5 and connected to a number of fuel injection valves 1 via solenoid valves 1a. If, for example, the engine stalls or the vehicle driver switches the engine off after high load operation and immediately restarts it, releases the accelerator pedal or tries repeatedly to start the engine, the pressure in the common rail 3 may be greater than is appropriate for starting, leading to excessive injection quantity and combustion noise. The system of the invention responds to such conditions by draining the pressurised fuel from the common rail 3 through the injectors 1 thereby keeping the fuel pressure in the common rail at a level suitable for the following engine start up. For draining, the solenoid valve 1a may be opened for a period of time shorter than the normal time lag between opening the solenoid valve and the beginning of opening movement of the needle valve 37 to drain high pressure fuel from the controlled chamber 43 of the injector to the fuel tank 9.

Patent GB-2351390-A (GB)
Title: A semiconductor material comprising two dopants
Inventor: KEAN ALISTAIR HENDERSON
IPC: H01L21/205
Filed: 1999-06-16
Abstract: A semiconductor layer is co-doped with two dopants. The first dopant is to generate charge carriers in the semiconductor material, and the second dopant is to promote atomic disorder within the material. When the semiconductor material is annealed, the second dopant becomes mobile and moves through the lattice so as to promote atomic disorder. This eliminates unwanted effects such as, for example, a reduction in the forbidden bandgap that can otherwise arise as a result of atomic ordering. The first dopant does not significantly diffuse during the annealing process. The amount of diffusion of the second dopant during the annealing can be increased by making the initial concentration of the second dopant non-uniform over the volume of the semiconductor material, e.g. by forming   w  -doped layers. The first and second dopants are preferably of the same conductivity type, and may be Carbon and beryllium respectively, for p-doping in an (Al,Ga,In) P layer. The material may be used as a cladding layer in a semiconductor laser.

Title: Synchronization control device for servomotors
Inventor: MAEZAWA HARUMI
IPC: G05B19/404
Filed: 1998-06-25
Abstract: An adder calculates the position droops of a main servomotor and an auxiliary servomotor when a main spindle and an auxiliary spindle are coupled through a work. The difference between the position droops is determined by a comparator before the coupling and a divider divides the position droop difference by the rotational speed of the auxiliary servomotor to determine the position droop difference per unit rotational speed. After the two spindles are coupled, a multiplier multiplies the position droop difference by the present rotational speed of the auxiliary servomotor and an adder adds the product to a position instruction to the auxiliary servomotor. This prevents excess torque from developing even when the main and auxiliary servomotors are operated synchronously with each other when connected through the work, eliminates influences of changes of the reduction ratio with time, and corrects misalignment that occurs at the time of coupling.
