Title: Weighcell
Inventor: HANNAM CLIFFORD
IPC: G01G23/08
Filed: 1987-08-20
Abstract: A weighcell has damping adjustment means comprising a piston 18 for immersion in a damping fluid in a dashpot 19, and means e.g. valve 21 for adjusting the damping effect of the piston within the dashpot. An element 24, 25 is provided for covering the dashpot, the element being mounted for movement between in a first position spaced from dashpot 19 in which the element locks the damping adjustment means (21) and the weighcell is operative and a second position in which the element 24, 25 covers the dashpot in sealing relation to preclude the spillage of damping fluid therefrom, locks the weighcell for transit purposes and as in its first position locks the damping adjustment means. Piston 18 is secured to one end of a threaded spindle 17 carrying the valve 21 whose spacing from the piston is adjustable by a notched wheel 23 threadably rotatable on the spindle 17. Element 24, 25 in the form of a notched wheel is rotatable on a threaded sleeve 22 formed integrally with the notched wheel 22. In the upper position in which it is spaced from the dashpot, element 24, 25 engages a locking washer 41 on the underside of wheel 23 and thereby locks wheel 23 and valve 21 in the adjusted position. In the lower position, element 24, 25, seals the dashpot 19, locks the weighcell and by its engagement with dashpot 19 locks the wheel 23 and valve 21 in the adjusted position. <IMAGE>

Patent GB-2213652-A (GB)
Title: Waveguide filters using expanded joints
Inventor: COBB GARY RAYMOND
IPC: H01P11/00
Filed: 1987-12-11
Abstract: A method of constructing waveguide filters of the type incorporating inductive posts, or pins, so as to provide improved microwave performance avoiding the use of soldering or brazing alloys at the important electrical interfaces within the waveguide structure. Using high conductivity base metals, the method requires only cold-flow expansion to provide highly conducting, or low resistance, joints. Low conductivity base metals may also be used so that application of the construction technique includes both jointing prior to, and/or jointing subsequent to, the surface deposition of a highly conductive metal coating by known means. The pins are bored at their ends, and a member, e.g. a ball (4), of greater hardness and diameter is forced in to expand the tubular end of the pin into good contact with the waveguide wall. <IMAGE>

Patent GB-2213754-A (GB)
Title: Multi-laminar explosive bonding
Inventor: HARDWICK ROY
IPC: B23K20/08
Filed: 1988-11-04
Abstract: A method of explosively bonding metal plates into a multi-laminar composite plate wherein the metal plates are assembled over a restraining means,eg an anvil,in overlapping spaced-apart relationship, a driver plate having a mass of at least the total mass of the plates to be bonded is disposed over the top plate of the assembly at a stand-off distance of at least half its thickness, a buffer layer of granular inert material is disposed between the driver plate and the top plate,and an explosive layer is placed on the driver plate and detonated in the direction parallel to the driver plate. The number of plates which can be bonded in a single operation can be increased by placing an explosive layer driver plate and a layer of granular inert material symmetrically on each side of an assembly of metal plates and detonating each explosive charge simultaneously. The method produces multi-laminar composite plates having improved uniformity of bond quality at the interfaces.In addition the method allows increased areas of metal plate to be bonded without producing excessive wave amplitude at the interfaces.

Patent GB-2227668-A (GB)
Title: Flushable ostomy and faecal incontinence pouches
Inventor: STEER PETER LESLIE
IPC: A61F5/445
Filed: 1989-02-06
Abstract: An ostomy pouch or a faecal incontinence pouch has an upper region having a slot 20 or a line of weakening or a series of holes which in normal use of the pouch are covered over by an adhesive strip 22. When it is desired to flush a full pouch down the WC, the adhesive strip is removed to open the top of the pouch. This reduces or destroys the bouyancy of the pouch and so aids flushing down a WC. The adhesive strip 22 may form part of a filter which also includes a gas filter member 26 and a further strip 24. <IMAGE>

Patent GB-2256765-A (GB)
Title: Imaging apparatus
Inventor: CURRIE ANTHONY
IPC: G01S13/90
Filed: 1989-11-28
Abstract: The earth's surface 2 is imaged (Figs. 1-3) by means of a synthetic aperture radar (SAR) system carried by an orbiting satellite 1. A previously transmitted radar pulse is scattered by feature 9 and received along at least two received beams 7a and 7b producing a plurality of samples of data per transmitted pulse. This allows the use of a lower pulse repetition frequency, PRF than would be possible with a conventional system allowing a wider swath 5 to be imaged whilst still satisfying the Nyquist criterion and maintaining spatial resolution in the azimuth direction. The beams from the future may either diverge to the satellite, as shown, or returns from a set of features corresponding to the plurality of returned beams may converge to the satellite (Fig. 7). Returned signals corresponding to each feature are combined, either at the satellite, or at a ground station. The system may be used for missile detection. Sound beams may be used for ultrasound (e.g. foetus or seabed) mapping. <IMAGE>

Title: Embroidery pattern data processor
Inventor: KOMURO KYOZI
IPC: D05B21/00
Filed: 1990-06-27
Abstract: An outline of a closed area to be embroidered stored in image memory 44 is displayed on a CRT 35 of an embroidery pattern data processor. A light pen 37 is used to designate vertexes of polygonal sections on the display surface of the CRT 35 to make up the closed area and this section data is stored in a memory 43. The CPU 17 reads the section data and determines the type of section i.e. an end section or fork section. This is then used to compute running stitch data and needle location data for embroidering the sections in such a way that a running stitch route within sections is carried out without producing cross threads which have previously been manually removed. The running stitch data and the needle location data control first, second and third circuit drives 39, 40, 41 in order to move the needle and workpiece to produce the desired pattern. <IMAGE>

Title: Manufacture of optical fibre preforms
Inventor: PILKINGTON CHRISTOPHER EDWARD
IPC: C03B23/045
Filed: 1991-05-10
Abstract: The diameter of the outer waveguide of an optical fibre preform (P) is increased by sleeving it with a tube (T). Axial alignment of preform and tube is achieved by butt-welding the preform (P) endwise to a rod (R) and smoothing the cylindrical surface of the butt weld to match the inner diameter of the tube (T). Irregularities in the diameters of core/cladding and outer waveguide of the preform (P) may be compensated for by stretching the combined preform (P) and tube (T) assembly before the addition of a further tube of known diameter.
