Title: PAL system colour processor
Inventor: KATSUYAMA HITOSHI
IPC: H04N9/89
Filed: 1985-04-19
Abstract: In a PAL colour signal processor a phase shifter 4 shifts, at every horizontal scanning interval, the phase of the colour burst component of the PAL colour video signals. A phase locked loop circuit 9 generates a signal at a frequency equal to the frequency of the colour burst component output from the phase shifter; and a time axis corrector 2 carries out time axis correction of the PAL colour video signals according to the difference between the phase of the signal generated by the phase locked loop circuit 9 and the phase of the colour component output from the phase shifter. A phase inverter 12 uses the signal generated by the phase locked loop circuit for inversion of the PAL phase of the PAL colour video signal; and a detector 23 detects the presence or absence of synchronization between the respective colour burst components as output by the phase shifter 4 at the respective horizontal scanning intervals. <IMAGE>

Title: Shock absorber for apparatus deployed under liquid
Inventor: MANK JAMES LEON
IPC: E21B33/035
Filed: 1985-07-19
Abstract: A shock absorber 10 (Fig. 1) for use submerged in a liquid environment comprises a piston 11, 15 slidable in a cylinder 12 to define an enclosure 18, and aperture means communicating between the enclosure and the liquid environment and providing a passage for environmental liquid. The aperture means may take the form of an orifice 20 in the piston head 15 and a tapered spigot 27 defining the orifice area as a function of piston position. An external compressive load force is resisted by pressurisation of the environmental liquid in the enclosure and the rate at which it can be expelled by the orifice defined by the piston position and the aperture (orifice) area variation with piston position may be chosen to give a desired deceleration characteristics to a load lowered onto the device. The use of environmental liquid means that a reservoir for the liquid is not required and the aperture means which replaces conventional valves results in a simpler and cheaper arrangement which also is not restricted in scale. The aperture means may be formed instead by an apertured cylinder wall the effective cross-sectional area of which aperture also may vary with piston position. <IMAGE>

Patent GB-2215563-A (GB)
Title: Data packet switching
Inventor: STOCKDALE JOHN ARNOLD
IPC: H04L12/54
Filed: 1989-02-03
Abstract: A method of an apparatus for interconnecting Line Processing Units (LPUs) comprising an information switch and/or concentrator system. Instead of using a standard bus system, each LPU has a number of duplex point to point serial links that are connected in a random or structured manner to provide a network of routes between the LPUs. Information is then transferred between source and destination LPUs as short packets. When the system is expanded by adding more LPUs, the network of serial point to point links expands to provide more routes and hence bandwidth to handle the increased information flow. Failure of a link in the network is not catastrophic as there are a number of different routes to any LPU and the system only degrades gracefully in the event of link failures.

Title: A high mobility semiconductor device
Inventor: DAWSON PHILIP
IPC: H01L31/0352
Filed: 1990-10-19
Abstract: The device (1) has a conduction channel region (2) forming a heterostructure defining first and second potential wells (3 and 5) provided by layers of semiconductor material bounded by barrier layers (4, 7, 8). The second potential well (5) provides an electron energy level (e5) which is lower in electron energy than the lowest electron energy level (e3) of the first potential well (3) and the barrier layer (4) separating the first and second potential wells (3 and 5) provides an intermediate electron energy level (e4) which is lower in electron energy than the lowest electron energy level (e3) of the first potential well (3) but is higher in electron energy than the lowest electron energy level (e5) of the second potential well (5) for causing conduction through the conduction channel region (2) to occur along the plane of the second potential well (5) by means of electrons transferred to the second potential well (5) from the first potential well (3) via the intermediate electron energy level (e4) provided by the barrier layer (4). Thus, the source of the conduction charge carriers is well separated from the conduction channel (5) so reducing the possibility of scattering of the conduction electrons and improving their mobility along the conduction channel. The device may be a F.E.T. and the transfer of electrons between the potential wells may be effected by an optical beam source 50. <IMAGE>

Title: Device to assist graphic data input using computer mouse or scanner: general desktop equipment
Inventor: COURTNEY WILLIAM ALEXANDER
IPC: G06F3/038
Filed: 1991-03-11
Abstract: This invention relates to an aid which assists in tracing and drawing when using a mouse to input drawing data into a computer. In addition the invention can be used to improve accuracy of data collection when using a hand held optical scanner, can be converted into a traditional drawing board, used as a copy holder for holding documents in a position convenient for use when manually transferring data into the computer, it can be used as paper trimmer, a paper folder and a storage device for holding floppy discs. A computer mouse (1) is attached to horizontal x and y axis rails (3, 4). This allows translational movement of the mouse but prevents rotational movement in the x-y plane making drawing and tracing accurate and easy. Independent x and y axis locks aid the drawing of lines in the x and y axis directions. The system can easily be adapted to trace diagrams from books of a range of thicknesses. Movement of the ball of the mouse and access to the tool box is possible without moving the mouse around the drawing surface. Hand held optical scanning is made more accurate by restricting the movement of the scanner to one dimension. The other uses of the device depend on the addition of inexpensive accessories. <IMAGE>
