Patent GB-2203989-A (GB)
Title: Method & device for effecting rotary action under water
Inventor: BOSWELL JOSEPH LEE
IPC: B63C11/52
Filed: 1988-04-25
Abstract: Concrete weight coating 20 on a subsea pipeline (18, Fig 1) is cut by a rotary saw blade 32 driven by a hydraulic motor 36. Air is supplied into a shroud 38 through linings 54, 56 from a compressor (70, Fig. 1). At least some water is replaced by air adjacent the blade. This reduces the power required and allows the blade to be used for longer periods before cracks develop from the bases of gullets at the blade edge. The reason for cracking is not fully understood, but tests show that the provision of air at least partly counteracts whatever effect the water has in promoting cracking. A modified shroud contains solidified foam-material (94, Fig. 4) which conforms closely to the blade, and the air supply may optionally be dispensed with. In the illustrated embodiment, the saw blade rotational axis is movable relative to the shroud 38 towards coating 20 from position 40 to position 42. In an alternative embodiment, the shroud (110, Fig. 5),moves with the saw blade towards the coating (20). A tool other than a saw blade may be used, such as a rotary grinder, buffer, wire wheel brush, or abrasive disc. The tools may be used for removing marine growth or corrosion from offshore structures. <IMAGE>
Patent GB-2205994-A (GB)
Title: A semiconductor device and a method for its production
Inventor: METHLEY DR STEVEN GARY
IPC: H01L31/0216
Filed: 1988-06-07
Abstract: It has now been discovered that errors in optical transmission systems are caused by intrinsic effects in silicon PIN photodiodes which incorporate a passivation layer, such as a silicon dioxide layer (8). Currently it is thought that the migration of mobile ions in the silicon dioxide layer (8) under the influence of the normal reverse biasing is causing inversion layers to be produced. The performance of silicon photodiodes and other semiconductor devices can be improved by forming a layer (16) of phosphosilicate glass over the silicon dioxide layer (8) and then negatively biasing this layer (16) for a period of several days. This causes the mobile ions to migrate into and become trapped within the phosphosilicate glass layer (16). <IMAGE>

Title: Manufacture of the themoplastics core of an optical communication cable
Inventor: HEYWOOD CLIFFORD
IPC: B29C48/00
Filed: 1988-07-08
Abstract: The thermoplastics core (1) is initially extruded with a circular cross-section and, following the cooling of the core, a plurality of sinusoidal grooves (11) for accommodating optical fibres are formed in the periphery of the core by means of heated conductors, for example in the form of forming wires (5), which are disposed into the sinusoidal configuration by continuous passage through openings (8) of an oscillating lay plate, and pressed into the core surface on passage with the core (1) through a cooled die (9), and then removed from the solidified themoplastics to leave the grooves impressed in the core. The conductors are preferably induction heated. The heated groove forming conductors may alternatively comprise the nip of co-operating endless belts (15, Fig.3), or rollers, having sinusoidal ridges which form the grooves. <IMAGE>

Title: Radio operated personal attack alarm
Inventor: SLATER JOHN RAYMOND
IPC: G08B21/02
Filed: 1989-01-19
Abstract: A radio operated personal attack alarm consists of a main alarm unit 10 containing the radio receiver, and incorporating a siren 12, strobe lights 13 and an illuminating message panel 11 upon which the address of the location being visited is written. The user would typically leave the main unit in a car parked nearby, carrying only a hand-held transmitter. In the event of an emergency, the user activates the alarm unit by means of the radio signal from the transmitter, and both the cry for help and the location are thus clearly communicated to a public place, with a request for immediate and appropriate assistance. <IMAGE>

Title: Improvements in self-energising disc brakes
Inventor: PRICE ANTHONY GEORGE
IPC: F16D65/14
Filed: 1989-06-09
Abstract: A self-energising disc brake is disclosed in which axial movement of pressure plates (2, 3) relatively away from each other is achieved in response to relative angular movement between the plates by the cooperation of balls with ramps (45) defined by the bases of pairs of recesses in which the balls are located. The radial cross-section of each recess is of non-circular outline having at least two discrete faces with which the ball co-operates as it moves along its respective ramp. There is therefore a reaction between the ball and each of the two faces, which enables the direction and magnitude of each reaction to be determined. <IMAGE>

Title: Method of controlling the operating speed of a processing machine
Inventor: BLEISCH GUENTER
IPC: B65B57/08
Filed: 1990-10-05
Abstract: The operating speed of a processing machine is reduced when temporarily reduced quality of the stock being processed occurs: for example when changing from one roll of wrapping material to another in a packaging machine. For this purpose the start of a processing phase (t1 to t5) of reduced reliability is determined, the operating speed is reduced from this instant to a value (nB*) which, during the processing phase of reduced reliability, at least guarantees the fulfilment of functions under the given processing conditions, and the operating speed is subsequently restored to the preset overall value (nB). Articles which may be double wrapped or incorrectly wrapped can be extracted from the processing line during the changeover. Fewer incorrectly wrapped articles need be diverted due to the reduced operating speed and the normal speed (nB) can be higher thereby optimising the overall output of the machine. <IMAGE>

Title: Submicron diameter particle detection utilizing high density array
Inventor: KNOLLENBERG ROBERT G
IPC: G01J1/44
Filed: 1992-02-25
Abstract: Submicron diameter particle detection utilizing a high density array (44) is disclosed. The high density array (44), such as a charge coupled device, is utilized to detect light scattered at a sensing region by particles illuminated by a light source, such as a laser source. Charge storage (46, 47) is utilized to buffer each data frame transferred from the high density array (44) and the multiple serial outputs are processed by parallel processing that includes threshold detection and analog-to- digital converting (49, 50). A micro-computer (58) and associated digital storage receives (60, 62) the digital outputs and provides outputs indicative of submicron particle sizing. Further improvement in minimum detectable particle sizing of particles carried by a fluid is realized by use of beam shaping optics to shape the illumination beam passed through the sensing region to form either an astigmatic (highly elliptical) beam cross-section, with the fluid being directed towards the imaging system orthogonal to the object plane, or a circular beam cross-section with the flow directed parallel to object plane, and with the focal point of the beam being substantially centrally positioned within the sensing region in either case. <IMAGE>

Title: Communication between processing elements in a network system
Inventor: CROSSLAND WILLIAM ALDEN
IPC: H04Q11/00
Filed: 1992-07-16
Abstract: In a network e.g. a distributed computer system, communication between pairs of e.g. processing elements is effected via an optical crossbar or matrix switch. Each processing element has means for storing in a queued sequential order the addresses of those system elements wishing to transmit to that element. The address at the head of the queue is broadcast to indicate that the system element is ready to receive a transmission from the requesting element. The technique reduces the system latency (average delay) and prevents queue jumping. The optical switch has 2 rectangular array of liquid crystal spatial light modulator elements. The means for storing queued addresses is a first-in-first-out (FIFO) store. <IMAGE>
