Title: Filament reinforced article and method of forming
Inventor: SIEMERS PAUL ALFRED
IPC: B22D19/14
Filed: 1991-04-24
Abstract: A method for forming a filament reinforced article involves spray depositing a layer (14) of matrix metal on a mandrel (10) and then forming a helical or spiral groove (16) in the surface of the deposited matrix metal (Fig 5). A reinforcing filament is then inserted into the groove, which maintains the inter-turn spacing of the filament oven if the surface is of non-uniform e.g. conical cross-section and is held in place by conventional means. The mandrel bearing the machined matrix metal layer and reinforcing filament layer are introduced into an r.f. plasma deposition chamber and an additional layer of matrix metal is deposited on the first layer and on the spiral wound filament on the surface thereof to embed the filament into the deposited matrix metal. Following the completion of several steps of deposition of matrix metal and machining the groove in the surface and inserting a spiral wound filament into the groove, the article so formed is consolidated by conventional means. The product formed has an essentially even spacing of filamentary reinforcement with a high volume fraction of reinforcing filament. The matrix metal may be a titanium base alloy, eg Ti-Al-Sn-Zr-Mo alloy. In the specific example a steel mandrel is first coated with Al2O3 prior to plasma spraying with the titanium matrix metal which after cooling becomes debounded from the titanium matrix. <IMAGE>

Patent GB-2275492-A (GB)
Title: Adjustable security bar
Inventor: MITCHELL WILLIAM GEORGE
IPC: E06B9/01
Filed: 1993-02-26
Abstract: An adjustable security bar comprising two, hollow, metal tubes, one tube (a) smaller in diameter, the male, which fits inside the larger tube (b), the female, so that the two can slide apart and widen, or be pushed together and contract to fit different sized apertures. On the end of the male tube, there is a warning sheath (e), which also acts as a bush, or gland to ensure the snug fit of the two inter-related tubes. If the tubes are extended too far, weakening the bar, the coloured sheath is exposed warning the user that a longer length tube is required. The bar is fixed at top and bottom, or at each side in the case of a horizontal fixing - therefore eliminating the need for a purpose-made frame and with the advantage that several bars, as many as required, can be set at intervals to cover a large aperture. Furthermore, in the case of a particularly awkward aperture, the bars can be fixed at differing expanded and contracted lengths. <IMAGE>
Patent GB-2264133-A (GB)
Title: Retaining mechanism for a tooth assembly
Inventor: GARMAN JAMES A
IPC: E02F9/28
Filed: 1992-06-22
Abstract: Retaining mechanisms are normally utilized for securing a tooth to an adapter. Many times the forces necessary to secure the retaining mechanism in an assembled position is not high enough to maintain assembly during use. In the subject arrangement, the retaining mechanism (16) includes a pin (40) having a means (60) thereon for forming a shoulder and a plurality of conical spring washers (42, 44, 46) each having an inner surface (52) defining an opening (53) having a diameter of a predetermined size which is smaller than the outer diameter of the shoulder means (60). During assembly, the shoulder means (60) of the pin (40) is forced through the opening (53) of the respective conical spring washers (42, 44, 46) from a concave side (48) thereof. In order to disassemble the pin (40), the shoulder means (60) of the pin (40) must be forced through the respective openings (53). In instances where the pin (40) must be removed from the same side that it is installed, a much higher force is required to force the shoulder means (60) through the opening (53) of the respective first, second, and thrird conical spring washers (42, 44, 46). Consequently, a retaining mechanism (16) is provided which has very high resistance to inadvertent disassembly during use.

Title: Improvements in digital image signal processing abstract
Inventor: WHITTAKER JAMES ROBERT
IPC: G06T5/20
Filed: 1994-11-14
Abstract: A raster scanned image may be scaled up or down for display on e.g. a portion of a computer display. This is achieved by dividing the image into a plurality of image cells each with a horizontal width less than that of the whole image. A smoothing algorithm is then applied to the lines of each cell in turn to generate new pixel data in dependence on the scaling operation to be performed. The scaling means stores a number of lines of data from a cell the number being dependent on the particular smoothing algorithm being used. To facilitate scanning of the image cell structure additional sync pulses are generated. These are cell horizontal and cell vertical sync pulses. <IMAGE>
