Patent GB-2174539-A (GB)
Title: Supporting semiconductor water during processing
Inventor: CORDINGLEY BRIAN VINCENT
IPC: H01L21/302
Filed: 1985-04-30
Abstract: A wafer of silicon, in which semiconductor devices are formed, is bonded to a supporting plate (5) of silicon to support it during certain processing steps. Specific examples relate to the profiling of peripheral edges of high voltage devices, and the passivation of pn junctions. The technique is also used to make diodes having very thin p and n layers. After the processing steps the supporting plate may typically be sawn to separate the devices. <IMAGE>

IPC: G03B27/52
Filed: 1985-08-06
Abstract: A photocopying device which is to be attached to a conventional photocopying machine 10, gives to the machine the capability of copying from bound books. The device has a V-shaped book rest 23 for supporting a book in an open condition and a scanning head 20 with a light source. The device can be mounted on a photocopying machine so that light from the scanning head is reflected from a page of the book back to the drum of the photocopying machine, along the same route as is taken by light travelling to the drum during conventional operation, without the device.
Patent GB-2180588-A (GB)
Title: Combination padlock
Inventor: KWOK WAY-KAY
IPC: E05B37/02
Filed: 1985-09-20
Abstract: A combination padlock 10, whose combination may be modified, comprises a body which has two sockets in which two legs 22,24 of a shackle 20 may be locked. When the shackle is unlocked, a member 40 provided within a cavity 70 formed as a continuation of one of the sockets may be displaced downwardly to cam against and displace a shaft 30. This in turn causes the disengagement of the digit wheels 32 from their associated bushings 34 and allows modification of the combination by rotation of the digit wheels. <IMAGE>

Title: Device for attaching a safety belt to a vehicle seat
Inventor: VOLKOV SERGEI ANDREEVICH
IPC: B60R22/26
Filed: 1985-12-11
Abstract: A device is proposed for attaching a safety belt (8) directly to a longitudinally adjustable vehicle seat (1). The seat has a slide member (3) which is slidable along a longitudinally extending guide (4). The device comprises a bracket (6) of substantially closed cross-section for the slide member and the guide to extend therethrough. The bracket is pivotable about a transverse axis (9) fixed with respect to the slide member (3). A safety belt attachment point (10) is spaced longitudinally from the pivot axis (9) so that tension (F) in an attached belt (8) will cause the bracket to pivot. The pivoting of the bracket is limited by an abutment (7) on the bracket which engages the guide (4) extending through the bracket. <IMAGE>

Title: Making sintered porous metal articles by centrifuging
Inventor: KOEHLER PAUL C
IPC: B22F3/06
Filed: 1986-01-28
Abstract: A method for making seamless, porous metal articles comprising:   (a) rotating a mold containing a stabilized suspension of a metal particulate at a rate and for a time such that the particulate is separated from the suspension and distributed on the interior wall of the mold, thereby forming a structure conforming to the interior wall of the mold, the rate of rotation being sufficiently high that at least 100 Gs of centrifugal acceleration is achieved at the interior wall of the structure, (b) drying the formed structure to provide a structure having green or unsintered strength, and (c) sintering the dried structure to remove volatile material and fuse the individual particles of the particulate to each other to form the seamless, porous metal article.   Metal articles in accordance with the invention have substantially uniform diameters, thicknesses and pore structures, have Bubble Point ratios of 1.5 or less, and find particular use as filters.
Patent GB-2185940-A (GB)
Title: Skip flotation aid
Inventor: CADDICK PETER EDWARD
IPC: B63B35/28
Filed: 1986-01-31
Abstract: A device for aiding the flotation of a loadable container, e.g. a skip (10), is in the form of a rectangular buoyant collar (12, 14) whose base is open to the water but which has a plurality of support beams (29) extending between opposed portions of the collar. In use, the container is placed into the internal space defined by the collar (which is already floating in the water) such that the base of the container rests on the support beams (29). The collar allows a greater load to be carried in the container, since the container is supported by the buoyant collar and by its own buoyancy due to displacement of the water. <IMAGE>

Title: Removing water from the hold of a sea-going vessel
Inventor: PEARSON JOHN ALAN
IPC: B63B13/00
Filed: 1989-01-30
Abstract: Apparatus for removing water from the hold of a sea-going vessel, comprises one or a series of upstanding ducts 10 or passageways positioned along one or more sides of the hold of the vessel each including spaced apertures 14 formed with an entry structure shaped to preclude or inhibit the flow of other than liquid therethrough e.g. by louvred entry structures 15. Preferably, the ducts or passageways extend over the full height of the available cargo space within the hold; the lower ends of the ducts or passageways may open onto the floor of the hold or lead directly to bilges positioned below the floor of the hold. The cross-sectional shape of the ducts or passageways is not critical and may be arranged for convenience of installation and inspection; the cross-sectional area of the ducts or passageways should, however, be sufficient to ensure unimpeded flow of water to the bilges in the most extreme conditions. <IMAGE>

Title: Security device for window
Inventor: PARSONS COLIN WILLIAM
IPC: E05C17/32
Filed: 1989-05-15
Abstract: A security device for fitting to a window comprises a pivoted linkage arrangement for securing at opposite ends to the window 2 and to fixed structure 1, respectively. The linkage arrangement can be pivotally displaced between one configuration in which the window 2 is closed and another configuration in which it holds the window partially open. The linkage arrangement comprises four plates 11, 12, 13, 14 hinged to one another end-to-end, with plate 11 at one end secured to the fixed structure e.g. the window frame 1 and plate 14 at the other end secured to the window 2. When the window is closed the linkage is folded so that the intermediate plates 12, 13 overlie one another and the plate 11 on the fixed structure, and the linkage resists unfolding should any force be applied to the window to open it. The linkage can be unfolded to permit the window to be partially opened and can be placed in a configuration which prevents the window closing. The plates may be bent. <IMAGE>

Title: Discharging condensate from gas boilers
Inventor: RICKSON KEITH PHILIP
IPC: F24H8/00
Filed: 1989-08-15
Abstract: Apparatus is provided for discharging condensate from a condensing type gas-fired appliance to a drain pipe, the apparatus comprising a tank 20 for receiving and collecting condensate discharged under gravity from the appliance and syphon means 21 adapted to commence discharge of the condensate from the tank to the drain pipe only when the collected condensate has risen to a predetermined uppermost level and to continue discharge of the condensate thereafter only until the collected condensate has fallen to a predetermined lowermost level. The lowermost chamber 27 of the tank is surmounted by a chamber 30 of smaller cross-sectional area. This causes the liquid in the upper chamber to rise relatively quickly and so to accelerate the establishment of a syphoning action. Syphoning action is promoted by restrictor 39 in tube 21. <IMAGE>
