Patent GB-2256899-A (GB)
Title: Nozzle wall construction.
Inventor: WOEHRL BERNHARD
IPC: F02K9/97
Filed: 1992-05-07
Abstract: A nozzle wall for rectangular-section hot gas nozzles of rocket or jet engines has an inner thermally conductive layer 12, an outer support layer 11 and an intermediate layer 13. The inner layer 12 is flexibly connected to the support layer 11 by means of wire retainers 8, and the intermediate layer 13, consisting preferably of granular ceramic material, is arranged to permit parallel sliding movement of the thermally conductive layer 12. The layer 12 may be formed by positioning retainers 8 and cooling tubes 9 on a copper plate 12a and then electrodepositing a copper layer 12b thereon. In an alternative arrangement (Fig. 3), the retainers (8') comprise hooks and an insulating layer (14) is deposited on the layer 12a. A method of manufacture is described. <IMAGE>

Title: Window insulator
Inventor: JOHNSON BRENIS E
IPC: E06B9/24
Filed: 1992-05-29
Abstract: A window insulator comprising an insulator core 101 of lightweight rigid insulating materials and/or flexible foam materials, the flexible foam materials being employed at least around the periphery of the core, enclosed by a cover for placement in a window for blocking the entry of sunlight into the interior portion of the structure, for reducing the level of sound energy passing through the window, and for substantially preventing or reducing the transfer of heat through the window. The insulator core may comprise a one-piece body 101 of lightweight, relatively rigid but hand-compressible insulating material, or flexible foam material. Alternatively, the core (Fig. 15A) may comprise an interior body (105) of lightweight rigid insulating materials, and flexible, resilient foam members (107) affixed to the peripheral edges of the interior body. The foam members may be affixed to the edges of the interior body by an adhesive, or they may be retained around the edges of the interior body within a saddle (111, Fig. 17B) of lightweight fabric extending outwardly from the interior body and affixed to the opposite faces of the interior body through a skirt of relatively heavy-duty fabric, which is stitched or otherwise affixed to the inner core portion. A cover (131, 133 Fig. 21) is removably mounted around the core. A port (123, Fig. 4A) may be provided through the insulator. <IMAGE>

Patent GB-2276732-A (GB)
Title: Fingerprint imaging
Inventor: SIBBALD ALASTAIR
IPC: A61B5/117
Filed: 1993-03-31
Abstract: An apparatus for producing an image of a fingerprint includes a right-angled prism 2, wherein the finger 6 is placed an the hypotenuse face 4 thereof. First and second polarising elements 12, 14 on die other two faces 8, 10 polarise light A entering the prism, and light B emerging to form the image respectively. Since light impinging on the prism/air boundary between the skin ridges is totally internally reflected maintaining polarisation whereas light, impinging an a prism/skin boundary is scattered, the second element 14 provides a screen to one of the types of light depending upon the relative orientation of the elements. This improves the contrast ratio of the image obtained. <IMAGE>

Title: Injection-moulding metal powders
Inventor: PIERIS DUNSTAN HARIDRA
IPC: B22F3/22
Filed: 1993-05-28
Abstract: Metal injection-moulded green bodies (2) are formed from a granulated feedstock comprising metal powder and a binder comprising:     a) 15-25 volume % paraffin wax   b) 20-30 volume % microcrystalline wax   c) 45-80 volume % polyethylene. The paraffin wax has two melting regions around 45 DEG C and 63 DEG C and the microcrystalline wax exhibits four melting regions in the range 62 DEG C and 144 DEG C. By raising the temperature of the oven in a controlled manner, first the paraffin wax and then the microcrystalline wax melts and is vaporised and entrained in a flow of carrier gas which flows over supporting trays (5), as indicated by the horizontal arrows (a). The requirement for wicking powder is eliminated by the staged removal of the wax and the polyethylene can subsequently be removed at a higher temperature by thermal depolymerisation in the same apparatus.

Title: Diffusion barriers for FET connections
Inventor: OKU TOMOKI
IPC: H01L21/338
Filed: 1993-06-24
Abstract: A field effect transistor includes source and drain electrodes (3a, 3b) disposed on a semiconductor substrate (1), a flat insulating film (4) disposed on the substrate (1) and having contact holes (4a, 4b) which are positioned on the source and drain electrodes (3a, 3b) and filled with metal films (7a, 7b), barrier metal layers (8a, 8b) disposed on the metal films (7a, 7b) covering the interfaces between the metal films (7a, 7b) and the insulating film (4), and source and drain wiring layers (9a, 9b) disposed on the barrier metal layers (8a, 8b). Impurity diffusion between the source (drain) electrode and the electrode wiring layer is effectively prevented by the barrier metal layer. In addition, since the interface between the metal film buried in the contact hole and the insulating film, is covered with the barrier metal layer, the mutual impurity diffusion between the electrode and the wiring layer along the interface is prevented by the barrier metal layer. <IMAGE>

IPC: A01D87/12
Filed: 1995-05-18
Abstract: Apparatus for lifting, moving and depositing silage bales, without damaging the plastic sheath covering the bale, consists of a pair of rounded lifting members which are placed below and at opposite sides of the bale 3 moved inwardly towards each other and lifted. Two interconnected frames 8, 9 move relative to each other in a first phase while said lifting members move towards each other and then move together in a second phase to lift the bale off the ground. The apparatus may be attached to a small tractor and operated by a single hydraulic cylinder 40 with the first and second phases occurring separately and consecutively. The apparatus may tilt backwards towards the tractor to hold the bale more stably and additional members 37, 38 may be provided to act to locate the bale positively on the lifting members. Depositing the bale is the reverse of the lifting operation, i.e. the second phase precedes the first.

Abstract: A printing apparatus has a keyboard for inputting data defining an image comprising at least one character and/or symbol to be printed on tape. First storage means are provided for holding font data with each character and/or symbol defined as a bit map of n bits. Second storage means hold a sizing algorithm, the printing apparatus being operable to print characters and/or symbols selectively in a first size as a bit map of n pixels and in a second size which is double the first size. Characters and/or symbols of the second size are generated from the font data according to the sizing algorithm so that each bit of the bit map of n bits is used to generate four pixels in the double sized printed character and/or symbol. The status of each of the four pixels is separately determined based on the status of the bits immediately surrounding the bit. The sizing algorithm is arranged to double the size of the symbols and/or characters defined by the n bit maps and to smooth the outline of curved and/or angled portions of at least some of the characters and/or symbols.

Title: Particle sorting
Inventor: ROSS VICTOR EMUL
IPC: B03B1/00
Filed: 1996-08-08
Abstract: In a method of sorting small particles, typically diamond (10) and gangue (12) particles having a size of 3mm or less, on the basis of differences in their thermal diffusivity the particles are firstly cooled e.g. in liquid nitrogen bath (14) to a low temperature below the freezing point of a liquid. Thereafter the particles are introduced into a body of the liquid such as water (18), the surface tension of the liquid previously having been adjusted such that particles (12) with relatively low thermal diffusivity cause freezing of the liquid with which they are in contact and are accordingly caused to float. Particles (10) with relatively high thermal diffusivity lose heat too rapidly to freeze the liquid and accordingly sink in the liquid. The floating and sunken particles are then recovered separately, in bins (24) and (26).
