Patent GB-2271256-A (GB)
Title: Error detection system
Inventor: GOULD ADAM F
IPC: H04L1/20
Filed: 1993-03-11
Abstract: An error detection system for discrete receiver. The error detection system indicates bad frames of binary information signal which contain distorted bits in excessive numbers so great as to cause a convolutional decoder to generate an incorrect, decoded signal. A signal decoded by a convolutional decoder (512) is re-encoded by an encoder (524), and the re-encoded signal (530) is compared with the signal received (506) by the receiver. When excessive numbers of re-encoded signal portions differ too greatly with corresponding portions of an actual, received signal, a bad frame indication is generated (590). <IMAGE>

Title: Memory checkpointing
Inventor: COGHLAN BRIAN ARTHUR
IPC: G06F11/14
Filed: 1993-11-03
Abstract: A method for checkpointing which does not involve copying of data and is almost instantaneous is described. At a checkpoint (4, 6), copying of the contents of an active one of a pair of locations in memory banks (A, B) is avoided by a simply designating the active location as being the backup for the checkpoint. Until there is a new write operation after the checkpoint, this location is regarded as both the active and the backup location. At the first write operation (3, 5) after the checkpoint, the write is carried out to the other, previously non-designated location. Control of writing and indicating of the status of the locations is carried out by updating two binary bits (M, R) for each pair of locations, namely, a modification indicator bit and a role indicator bit. The modification bits are stored on a resettable RAM for almost instantaneous checkpointing where the location granularity is that of a write operation. <IMAGE>

Patent GB-2277219-A (GB)
Title: Lidar signal processing
Inventor: FLOCKENCIER STUART WAYNE
IPC: G01S17/89
Filed: 1994-03-24
Abstract: Light pulses are reflected off of a target, received by optical equipment, converted 80, 82, 84 into digital electrical signals, and then processed 74, 76 to obtain range information by measuring the time delay between a transmitted signal and a received signal. The invention includes a windowing system which defines a "window" in memory 72 within which the return signal is expected, and searches only within this window for the return pulses. Alternatively, (fig 3), the system detects (306) the maximum amplitude of the received signal in real time, and stores the current value of a counter 90 used to clock data into memory 72, which is then used to define the window. A timing delay system may conserve memory by delaying storage of data until a return pulse is actually received. <IMAGE>

Title: Controlling movement of articles in a manufacturing installation
Inventor: EVANS DARREL
IPC: G05B19/418
Filed: 1994-03-28
Abstract: Code means are assigned to article processing stations, such as a casting mould C and a subsequent station B (eg. a rolling mill) in a steel mill, and to article storage regions P1, P2, P3, P4. The code means may be in the form of transponders T inset into the floor at the various stations and regions. To move an article within the installation, a CPU transmits the codes of the article pickup and destination positions to an article conveying vehicle V. The vehicle V then moves to the pickup point, picks up the required article after checking for code match with the pickup point transponder T, transports the article to the destination and deposits the article after checking for a code match with the destination transponder T. Signal communications may be by radio waves or by optical, laser, or inductive coupling means. <IMAGE>

Title: Rotatable wheel driven by gravity
Inventor: HUNG MING-TUNG
IPC: F03G7/10
Filed: 1995-04-05
Abstract: The wheel has a horizontal shaft and a numbed of symmetrical radial frames A. Each radial frame A has a sub-axis B which engages with a movable means C. Bulges D are disposed on a lateral side of the movable means C or on the radial frames A at a different distances from the sub-axis B or from the rotary shaft, so that when the movable means C drops down due to gravity force, it makes an alternate contact with the bulges D and presses against the radial frame A through the bulge thus creating an unbalanced torque on radial frame to drive the wheel in one direction. The wheel can be installed above ground or under water, or with one half above the water surface and one half below the water surface provided that the specific gravity of movable means be less than one. In such circumstances, gravity force and floating force of movable means joint together to create an unbalanced effect on radial frames to drive rotary wheel to rotate in one direction. It is alleged that the wheel rotates perpetually without consuming energy and can be used to generate electricity.

Title: Mineral insulated cable manufacture
Inventor: JOHNSON OLIVER SANDERS
IPC: H01B13/004
Filed: 1995-06-02
Abstract: A copper tube 2 contains a copper rod 4 held in the required spatial distribution by conductor guide 1. Mineral insulating powder 8 is introduced continuously through tubes 6 into space 7, immediately before the point at which the diameter of the tube is being reduced substantially, i.e. by 8%+. The quantity of powder in the space is limited and uncompressed, so as not to impede the diameter reduction. This arrangement ensures that the reduced diameter section 18 is uniformly filled with powder. The initial large diameter of tube 2 provides room for tubes 6 and 11. The initial tube 2 can be a long discrete length, which is filled in a substantially horizontal plane, or made continuously from strip, while the conductor rod(s) and the powder are introduced. The filled preform is then converted to cable by known methods. <IMAGE>
Patent GB-2302049-A (GB)
Title: Centrifugal separator
Inventor: PURVEY RONALD JAMES
IPC: B04B5/00
Filed: 1995-06-10
Abstract: A centrifugal separator (10, Figure 1) for separating solid particles from a liquid, eg engine lubricant, includes a rotor container (20) to which the liquid is supplied at elevated pressure and caused to escape via tangentially directed nozzles (28) to create high speed rotation of the rotor and centrifugal separation forces within the liquid. In order to avoid problems of noise and vibration when the rotor empties as it spins to rest, it is characterised by a check valve (40) incorporated between separation and outflow chambers (36, 37) of the rotor which makes use of the normally conical shape of the partition wall (35) between the chambers that defines a central, annular, transfer aperture (39). The check valve includes a body (41) disposed to overlie, be biased towards and seat against, the inclined face of the partition wall to form a low flow-resistance valve from parts cheap enough to dispose of with the rotor. Notwithstanding the ability for low cost manufacture, the check valve is able to provide a good seal that retains liquid in the separation chamber, not only reducing wind-down noise but also enabling the centrifugal separator to commence working more quickly after frequent engine stops, and on both counts is particularly suited to passenger car engines.

Title: Modelling spatial distribution of geometric objects in a discontinuous environment e.g. geological faults
Inventor: CACAS MARIE-CHRISTINE
IPC: G01V1/28
Filed: 1995-10-18
Abstract: In a method for modelling, in particular, the fault configuration of a subsoil zone having a base network made up of major faults detected by exploration of the zone, minor faults not detected during the exploration, corresponding to a same type of tectonic event, are positioned in this network. The base network is analysed to determine its fractal characteristics and minor faults are selected at random from among a set of minor faults observing a given statistical distribution. Each of these minor faults is sited by determining the fractal dimension of the base network as well as the density function defining the distribution of fault lengths, selecting a set of fault lengths using the defined distribution of lengths, and positioning each fault in the base network at random and testing the position to check that the network of faults as positioned retains a fractal nature. <IMAGE>

Title: High-speed counter circuit
Inventor: OH JONG HOON
IPC: H03K23/58
Filed: 1996-05-15
Abstract: A high-speed counter circuit has an input line (31) for inputting a clock signal, and at least two bit counters (30, 32) for generating a count value of at least two bits in response to the clock signal from the input line. A clock synchronizing circuit (GA2) acts to transfer the clock signal from the input line (31) to the lower-order bit counter (32). A delay circuit (GA1) delays the clock signal from the input line (31) by a propagation delay time of the clock synchronizing circuit (GA2) and applies the delayed clock signal to the highest-order bit counter (30). The high-speed counter circuit minimizes the delay from the application of the clock signal to the generation of the count value to enhance the operational speed of the counter circuit.

Title: BNC/D-Sub signal auto-selection circuit
Inventor: SHIM JAE-GYOU
IPC: G09G1/16
Filed: 1996-10-04
Abstract: A circuit for automatically selecting either a BNC video signal or a D-SUB video signal applied to a monitor from an external computer system is described. A detector 10 discriminates a signal currently being input as a D-SUB or a BNC synchronising signal input from the computer system. A D-SUB/BNC selecting integrated circuit 20 generates a predetermined operating signal, responsive to a control signal input from the detector, to either a D-SUB driving circuit 30 or a BNC driving circuit 40. A D-SUB driving circuit 30 supplies a D-SUB video signal (Red, Green and Blue) to a cathode ray tube, responsive to the said operating signal. A BNC driving circuit 40 supplies a BNC video signal (Red, Green and Blue) to the cathode ray tube, responsive to the operating signal. As a result, a video monitor is able separately to amplify respective video component signals in a video signal by using automatic selection circuits, such as a single block incorporating a pair of inverters, thereby enhancing the response characteristics of the circuit.
