Filed: 1985-10-15
Abstract: An injection mould 1 comprises two mould halves 2 and 3 which are pivotally mounted on a base member 4 to which are secured tapered mould pins 9 and 10. When the mould 1 is closed molten polypropylene is injected through injection holes and into the cavities in the mould 1 circumjacent mould pins 9 and 10. After injection is complete the polypropylene is allowed to cool. The mould 1 is opened and two wall plugs are removed from the respective mould pins 9 and 10. The mould halves are locked in their closed position by means of a fastener 11. <IMAGE>

Title: A coupling for a toy drive
Inventor: HAASE HORST
IPC: F16D43/18
Filed: 1985-12-02
Abstract: A coupling for a toy drive particularly a steering system for a toy vehicle consists of an electric motor 1 which drives a disc 7 on which are mounted centrifugal bodies 4. The steering mechanism is driven by a shaft 3 on which is mounted a coupling sleeve 5. Apon rotation of the motor the centrifugal bodies 4 are thrown outwardly into frictional engagement with the sleeve 5. The frictional engagement results in the fact that only a predetermined maximum torque can be delivered so if the steering mechanism becomes jammed the coupling slips and the motor is not overloaded. <IMAGE>

Patent GB-2198016-A (GB)
Title: Manchester decoders
Inventor: TRINDER JULIAN RICHARD
IPC: H04L7/02
Filed: 1986-11-27
Abstract: A Manchester decoder includes a majority conversion circuit 50 receiving a signal for decoding at an input 52, the circuit 50 providing a two-out-of three majority output to eliminate isolated single sample features in the input signal. The converted signal is supplied to a half-bit sample comparator 60 including a shift register 61, "late" and "early" pairs of samples being derived from the shift register 61 and tested for polarity coincidence in EX-NOR gates 62,63. A timing control circuit 70 including a five-bit counter 71 provides a sample signal at times dependent on the outputs of the gates 62,63 by virtue of the counter 71 being arranged to reset to a different count value depending on the output states of the gates 62,63. An output latch circuit 80 latches a sample derived from a stage of the shift register 61 as a data output signal, in response to the sample signal from the timing control circuit 70. The Manchester decoder is able to decode a highly distorted input signal (which may exhibit poor pulse rise-time and significant pulse droop) with edge jitter, in the presence of high levels of FM-receiver noise, by virtue of steering towards an optimum phase of signal determination unconstrained by the position of signal edges. <IMAGE>

Title: Method of detecting maximum cylinder pressure in internal combustion engine
Inventor: TANAKA AKIRA
IPC: F02P5/152
Filed: 1986-12-02
Abstract: The output of a cylinder pressure sensor is digitally sampled and the rate of change of the sampled data is successively calculated. Each calculated rate of change is compared with that one sample earlier, and when the former is found to exceed the latter by more than a predetermined amount it is determined that knocking has occurred. When knocking is not found, the sampled data at the time when the rate of change becomes zero or negative is defined to be the maximum cylinder pressure Pmax. At the same time, the maximum cylinder pressure angle is determined by measuring the time lapse between a reference point such as piston TDC and the point of time at which the rate of change in the sampled data becomes zero, and converting the measured time lapse into the corresponding change in crankshaft angle. <IMAGE>

Filed: 1987-05-29
Abstract: A thermal fuse comprises a substrate (1), suitably of ceramic material, with a pair of tinned film conductors (5, 6) provided thereon with a gap (7) between them. A short electrically conducting wire (11), (eg 5mm long) of a solder alloy is located across the gap (7) with opposite ends, (11A, 11B) of the wire in contact with the conductors (5, 6). The ends (11A, 11B) of the wire (11) are heat-fused to the conductors (5, 6) while the substrate (1) is heated, but surprisingly, without damaging the wire (11). A film resistance element (2) with terminations (3) and (4) is also provided on the substrate (1), electrically connected in series with the wire (11). If the resistance element (2) overheats as a result of an electrical overload in a circuit in which the assembly is connected the wire (11) melts and withdraws onto the conductors (5, 6) thereby breaking the circuit. <IMAGE>

Title: Hierarchical file system
Inventor: BRUFFEY BILL M
IPC: G06F12/00
Filed: 1987-06-29
Abstract: A hierarchical filing system provides a cataloging of data stored in various locations within a memory device. An upside-down tree type structure provides a downwardly expanding cataloging structure wherein directories provide for further branchings. A branching from a directory is terminated when a file is reached. Each directory is assigned a unique directory identifier value. Then, each file or directory is coupled with the directory identifier value of its parent to provide the interconnection necessary to form the cataloging structure. The complete cataloging structure is organized in the leaf nodes of a B-Tree structure and distributed in an ascending order of the key values to provide a systematic search for a given key. Each file is capable of storing a predetermined number of location description information when data is segmented into non-contiguous segments in memory. A file extents record is used to maintain record of the further segmentation. File location information is kept in the form of file extents descriptors in the leaf nodes of the separate File Extents B-Tree. This extents information is sorted in an ascending order based on a key comprised of a unique file number of a file relative starting block location of the file extent.

Title: Improvements in or relating to clock pulse generating circuits
Inventor: SIMPSON RICHARD DAVID
IPC: G06F1/12
Filed: 1988-06-30
Abstract: A clock generating circuit for use in a signal processing circuit to enable it to be synchronised with other circuits in response to a reset signal uses a multi-state circuit 2, which is cyclically stepped through its states by a clock drive signal and a decoder 4, responsive to the state of the multi-state circuit to produce the required clock pulses. The reset signal 7 is used with delay 25, inverters 26, 27, and NAND gates 22, 23, 24 to stop the multi-state circuit at a particular state and hold it there for a period of time enabling other similar clock pulse generating circuits to reach the same state and be held there. At the end of the period of time the multi-state circuits resume their cyclic stepping with all the circuits in synchronism. <IMAGE>

Title: Pattern-matching sheet-joining
Inventor: NOMURA ETSUZO
IPC: D05B79/00
Filed: 1989-01-27
Abstract: A machine e.g. a sewing machine for joining two sheets having the same pattern with the patterns matching, has pattern detecting photo-sensor arrangements M1, M2 which generate intensity data for each sheet of at least two different wavelengths. As shown color data at three wavelengths (e.g. red, green & blue) are processed to correctly discriminate elements of a pattern having colors of similar brightnesses, and to accurately pick out pattern elements with faint colors from behind outstanding pattern elements. One way of processing the data includes calculating differences between intensity data for different colors. Another way includes selecting the color that has the largest intensity change. Any mismatch detected at M3 causes a sheet-moving means M4 to move one of the sheets until the patterns are aligned.
