Title: Grouted pipe joint for polyolefin lined pipes.
Inventor: GREIG JOHN MARTYN
IPC: F16L47/02
Filed: 1989-08-22
Abstract: PCT No. PCT/GB90/01308 Sec. 371 Date Apr. 1, 1991 Sec. 102(e) Date Apr. 1, 1991 PCT Filed Aug. 20, 1990 PCT Pub. No. WO91/02918 PCT Pub. Date Mar. 7, 1990.A joint between pipes (12, 14) each having a liner (16, 18) of polyolefin such as polythene. The pipes are spaced apart and the liner protrudes from each and is joined to its neighbor by a fusion coupling (20). The pipes are interconnected by a shell (24, 26, 28) and epxoy cement grout (34) fills the space between the liner and the shell. The liner is inserted in the pipe after it has been reduced in diameter by passing it through a die. The pressure of gas or liquid within the liner in use is greater than the liner can withstand alone but the grout transfers pressure loading to the shell. In modifications the coupling is replaced by a PECAT coupling or by flanged couplings joined to the pipes by butt fusion or by electrofusion directly or using electrofusion couplers. The liner may be locked in position using electrofusion fittings to prevent change of dimensions by reversion.

Title: Crash sensors
Inventor: THUEN TORBJORN
IPC: G01P15/08
Filed: 1990-11-22
Abstract: A sensor for initiating air bag inflation during automobile crashes includes a hermetically sealed container 2 containing a fluid for controlling the movement of an inertia mass 6. If the crash is of sufficient severity and duration, the inertia mass 6 moves to close a pair of contacts 14 and 15 and thus cause air bag inflation. The hermetic sealing leaves the operating characteristics of the sensor unchanged despite changes in ambient atmospheric pressure. The fluid may be air or other gases such as helium of helium mixed with air to achieve a desirable operating characteristic. <IMAGE>

Title: High frequency coil which avoids core damage from metal casing burr
Inventor: MAMIYA YASUNORI
IPC: H01F21/06
Filed: 1991-06-19
Abstract: A bobbin (1) provides a coil (3) wound on the outer peripheral surface and allows a threaded core (5) to be screwed on the inner peripheral surface. This bobbin is covered with a jar-like core (8) and a metal case (9). The jar-like core (8) and the metal case (9) provide through holes (11, 31) for receiving a driver used to handle the threaded core. The edge of the through hole of the metal case (11) is located radially inside that of the through hole (31) of the jar-like core. This prevents the edge of the through hole of the jar-like core from being broken by a burr (14) formed on the edge of the through hole of the metal case. Other methods of avoiding core damage caused by the burr on the metal casing hole edge may include having a stepped or bevelled edge on the core hole. <IMAGE>

Patent GB-2276960-A (GB)
Title: Processor and method for DFT computation
Inventor: JONES KEITH JOHN
IPC: G06F17/14
Filed: 1993-04-08
Abstract: An N-point DFT is calculated using arrays 2, 3 of processing elements PE wherein outputs and partial outputs are calculated recursively, advantageously using Cordic arithmetic, to permit systolic computation. More generally, M arrays each of M dimensions may be used, each dimension having the Mth root of N processing elements along it. Partial DFT outputs (e.g. row and column outputs) are produced by processing along the dimensions in respective different arrays (e.g. 2 and 3). Each final DFT output or partial DFT output is produced by the addition of the neck individual input data or partial DFT output to the output of the previous recursion and multiplication by the same complex experimental term or, in the case of the last recursion for all arrays except the Mth array, by a different complex exponential term to take account of the required twiddle factor. The invention permits improved utilisation of processing elements and avoids the need for global communication of data across the arrays. <IMAGE>

IPC: G06F17/40
Filed: 1993-08-13
Abstract: An apparatus (1) has a source data bank (2) connected to a time stamp device (3) for rapid reception and non-volatile storage of data from disparate sources. Fixed program processors (7) are separated from the data bank by a one-way interface (6) which prevents feedback of data to the bank, to help ensure data integrity. Each processor (7) relates, for example, to a particular product in an industrial process. This provides an interim output on a line (8). A variable processor (9) includes a respective hard-wired data cell associated with each output field of a processor (7) to provide a second interim output on a line (11) at a higher level than the first interim output. An interpreter (13), e.g an expert system, provides a further, higher level of processing according to interactive inputs on a line (14) to provide a final output on a line (15). The fixed processors (7) and variable processor (9) provide an ideal combination for obtaining data specific to particular products or any other parameter and a higher level of processed data to provide overview information. Faults may be easily tracked to their source. <IMAGE>

Title: Voltage regulator for a hand-held appliance
Inventor: COCKROFT JAMES BENZIE
IPC: G05F3/20
Filed: 1993-09-10
Abstract: A hand-held electric appliance, such as a hair-clipper, has a voltage regulator including a transistor Q1 serially connected to a source of full-wave rectified alternating current potential. The transistor Q1 is an enhanced, metal oxide semi-conductor, field-effect transistor that regulates a rectified alternating current potential and outputs a regulated potential to a d.c. motor M. A biasing resistor R1 and zener diode Z1 are connected to the transistor Q1 for biasing the transistor, thereby enabling regulation of the rectified potential. Such a regulator improves the efficiency of the motor, as well as increasing the life of the motor and reducing the size of the required suppression components. A filter circuit L1, C2, R4 reduces radio frequency interference. <IMAGE>

Title: Dashpot
Inventor: NASH RICHARD CHRISTOPHER
IPC: F16F9/06
Filed: 1994-05-19
Abstract: A liquid dashpot has a casing comprising a main body 4 and bottom cover 12. The main body contains a liquid chamber 16 which is divided into two discrete spaces (16a, 16b) (figure 3) by a vane member (28). One end wall 8 of the chamber has porting (36a) (figure 3) and 36b passage means 34 formed between the outer face of said wall and the bottom cover to provide restricted communication between the chamber spaces. A flexible diaphragm 50 forms a compensation chamber 52 on the bottom cover subject to atmospheric pressure. The chamber 52 can communicate with the spaces within the liquid chamber through non-return means 54 that block super-atmospheric flow to the compensating chamber. The porting (36a) 36b, 56 and the communicating passage means 34 between the spaces and the compensating chamber are formed integrally in the die-cast main body and/or the bottom cover, requiring no machining. Assembly is facilitated by bringing together the bottom cover 12, flexible diaphragm 50 and non-return means 54 as a sub-assembly. <IMAGE>
