Title: System storing and reading digital information, optionally protected by further error correcting code
Inventor: LUYT BALTHASAR ANTONIUS GERARD
IPC: G11B20/18
Filed: 1987-02-20
Abstract: A method and apparatus for storing and reading digital information, in which the recorded information is protected by a double symbol correcting code involving interleaving between the codes and also employing an additional, optional error correcting code. The information is organized in sectors, which are arranged such that following the synchronization and header information sub-header information is provided to indicate different sub-modes of operation of the playback apparatus. During playback, when a first sub-mode indication value is detected, this means the sector contains further error protection information, that is, the optional error correcting code, for which purpose a special decoder is activated. When the sub-mode detector detects a second sub-mode indication value, this means that further user information is present at the location where the optional error protection information would have been, and the special decoder is not activated.

Title: Detecting electrical currents
Inventor: GREASLEY JOHN MICHAEL
IPC: G01R19/165
Filed: 1989-10-21
Abstract: In an arrangement to detect when a current I reaches a threshold, pulses are applied by a generator (2) to a primary winding L2 of a core M1 and corresponding pulses are thereby induced in a secondary winding L3. When a direct current applied to a further winding L4 reaches a threshold level, the core M1 becomes saturated and the amplitude of the pulses induced in the secondary winding L3 is restricted. A comparator (6) comparing the output of the secondary winding L3 with a reference P1 then changes its output, thereby to affect a trip circuit (7) and LED indicator (8). The trip circuit (7) may be used to switch off sound producing equipment in a car on detecting an incoming telephone call current I. <IMAGE>

Title: Thread trimmer for sewing machine
Inventor: PRAIS EUGENE RANDAL
IPC: D05B65/02
Filed: 1991-11-22
Abstract: The needle (127) and looper (167) threads of a chain stitch sewing machine having an in-line looper system, in particular a cylinder bed machine, are severed in the region below the needle plate (129) and above the spreader (174) by a movable knife (138) slidably mounted between a stationary knife (134) and a spring (176). The movable knife has a pair of axially offset barbs (198, 199) adapted respectively to hook the needle and looper thread loops at one side of each when the knife is advanced, e.g. by an air cylinder and to draw back the threads into cutting engagement with the stationary knife (134) which also traps the severed end of the looperthread. Each needle of a multi-needle machine has an associated movable knife (138). Pulling devices make slack in both threads prior to severing. <IMAGE>

Title: Micro-controller unit
Inventor: LEE BYEONGJUN
IPC: G06F9/26
Filed: 1992-01-02
Abstract: A micro-controller unit 1 for accessing an external extended memory 2 includes an external memory control block 13, an external timing control block 14, and an internal memory 11. A reset detection circuit 15 responsive to an external reset signal for initialising the MCU and an external clock, detects whether the micro-controller unit is reset or not. A memory access clock generation circuit 16 receives an output signal from the reset detection circuit and generates a clock signal to selectively access an internal or external extended memory; A latch 17 receives the clock signal and a memory interface signal (read/write signal) for applying a memory access selection signal to each of the external memory control block 13, the external timing control block 14 and the internal memory 11. In this way memory selection is performed by the reset signal and memory interface and the need for an additional input control signal is therefore eliminated. <IMAGE>

Patent GB-2255424-A (GB)
Title: Fluid flow control valves
Inventor: DURRANT DAVID KENNETH
IPC: E03D13/00
Filed: 1992-04-28
Abstract: A fluid flow control valve, which opens in response to a decrease in fluid (water) pressure at its inlet, comprises a valve chamber (17) having an inlet (15), an outlet (18) and a valve seat (21) therebetween. A diaphragm (32) can engage the valve seat (21) to close the valve. A sub-chamber (22), separated from the valve chamber (17) by the diaphragm, has an outlet that can be uncovered to release pressure therefrom. A Bourdon tube (30) receiving inlet fluid pressure is arranged to uncover the outlet in response to a drop in such pressure below a predetermined value, allowing fluid to escape from the second chamber (22) so that the diaphragm (32) moves off its valve seat to open the valve. A subsequent increase in inlet fluid pressure (to mains pressure) causes the Bourdon tube (30) to seal the sub-chamber outlet again, with fluid bleeding into the sub-chamber and causing the diaphragm (32) to move onto its valve seat to close the valve. The pressure at which the valve opens may be determined by adjustment of a screw-threaded nozzle 29 fitted on the outlet from the sub-chamber (22). The valve is used in a flushing system for a urinal, being opened by drop in inlet water pressure which results from opening of a wash-basin tap. <IMAGE>

Title: Control system with plural manual control members.
Inventor: HODGSON J PAUL
IPC: B64C13/12
Filed: 1992-06-11
Abstract: At least two manually operable control members provide a single output function to control an operating system eg. an aircraft flight control system, weapons firing system or hazardous manufacturing process. Each control member, eg flight control sidestick (10, 11), is moveable between an out-of-use, eg central, position and a range of in-use positions. Selection means detect movement of a control member (10, 11) from the out-of-use position to an in-use position and in response thereto connect the output function of that control member (10, 11) to the operating system irrespective of the position of any other control member. Thus an operator can be certain of being in control by engaging the out of-use position, even if momentarily, before continuing to operate the control member. The selection means may include microswitches 14, 15, flip- flop device 17 and coils 18, 19 in a relay 16. <IMAGE>
