Patent GB-2111347-A (GB)
Title: Method of pulse examination
Inventor: CRIBBS ROBERT
IPC: G01S7/52
Filed: 1982-11-22
Abstract: A method of pulse examination which is particularly easily carried out using a container (10). The method entails matching the impedance of a a liquid couplant in the container (10), to the impedance of the tissue of an examined female breast. The time per unit distance taken for ultrasonic pulses to travel through breast tissue and a reference liquid respectively are found and the reference liquid mixed with a second liquid in a ratio dependent on the difference between those times to form a liquid couplant with an impedance similar to the impedance of the breast tissue. The method thus compensates simply but accurately for velocity variations in the breasts of different patients. The liquid container (10) contains a liquid in contact with the top of a breast being ultrasonically scanned. The container comprises fluid- impervious material (20) and an opening (26) to be placed about the breasts of a female torso. Inflatable sealing means (28) seals the perimeter of the opening against the body. The method of use of the container (10) enables more rapid, accurate and meaningful scanning than was previously possible. <IMAGE>

Title: Mining of minerals
Inventor: BUTCHER MICHAEL JAMES AYLING
IPC: E21C41/20
Filed: 1983-04-25
Abstract: A method of mining a mineral, such as potash, from a panel 2 of potash-containing material in which slices of the panel are cut, one after the other, by the repeated passage of a cutting machine 7 from an end of the panel to another end thereof. Cut material is removed by advanceable belt-conveyor 12 extending from an end of the panel to the other end thereof and is then fed to a suitable point where the mineral is separated from the material. Non-mineral- containing material, conveniently that remaining after separation of mineral therefrom, is supplied to another advanceable belt-conveyor 13 extending from an end of the space left by removed slices to another end of that space. This is used to fill, from one end to the other, that space most remote from a slice being cut, in order to support the roof left by the removal of slices. <IMAGE>

Title: Liquid phase epitaxy apparatus
Inventor: BRICE JOHN CHADWICK
IPC: C30B19/06
Filed: 1983-04-27
Abstract: A sliding boat liquid phase epitaxy apparatus comprising a base 1, substrate support means 2 superposed on the base 1, and a well member 5 abutting and disposed above the substrate support means 2 and having at least one well 22 capable of containing growth solution 28. The substrate support means 2 comprise a recessed substrate holder 16 which can be disposed under and in registration with the well 22. The well member 5 and the substrate support means 2 are relatively slidable in the length direction of the apparatus. A problem encountered in growing layers of material by a liquid phase epitaxy process using a sliding boat apparatus is to achieve adequate wipe-off of growth solution in order to provide a grown layer having a smooth surface. The bottom of the well member 5 is provided with a plurality of grooves 23 on the side of the/each well which traverses or is traversed by the recessed substrate holder 16 after growth of an epitaxial layer, and wherein the grooves 23 extend across at least a width of the well member 5 which is greater than and includes the width of the substrate holder recess 16. <IMAGE>

Title: Hydrochloric acid chemical laser
Inventor: BRUNET HENRI
IPC: H01S3/036
Filed: 1983-06-23
Abstract: Molecular chlorine from a tank (1) is dissociated by an electrical discharge along a dissociation chamber (3,4,5) to provide atomic chlorine at the inlet to a nozzle (7). Hydriodic acid is injected via openings (13) into the nozzle and reacts with the atomic chlorine to produce excited hydrochloric acid which passes transversally through a laser chamber (19). The exhaust gases are received in an exhaust chamber (23) which includes zeolite to absorb the exhaust gases and to maintain suction for the required period of laser operation. Unlike similar systems using calcium to absorb the exhaust gases, zeolite does not need preheating. Such lasers may be used on board aircraft, for example. <IMAGE>

Title: Transport system for workpieces
Inventor: DAVIDSON MATS INGVAR
IPC: B65G35/00
Filed: 1983-07-14
Abstract: A system for transporting work pieces, preferably in the garment industry, includes a main conveyor 101 and a number of branch conveyors 1 each forming a loop from the main conveyor through a working station and back to the main conveyor. The main conveyor is provided with a pinion driver continuous corrugated belt running around a track and carrying dogs to force carriers 2 for the work pieces to move around the track. The branch conveyors are each provided with a downwardly sloping section 132 to let the carriers move from the main conveyor to the work station by means of gravity. From the working station the carriers 2 are moved back up to the main conveyor by means of a discontinuous drive comprising a piston-and-cylinder device reciprocating a chain carrying detents which engage and propel the carriers on the drive stroke of the device but pivot so as not to entrain the carriers on the return stroke of the device. The carriers may be equipped with address elements which cooperate mechanically with sensing and track-setting apparatus to automatically route the carriers. <IMAGE>

Patent GB-2134268-A (GB)
Title: Capacitive displacement transducers
Inventor: HATTON JOHN SAMUEL
IPC: G01D5/241
Filed: 1984-01-26
Abstract: A transducer gives an output which is dependent upon the relative displacement of two sets of spaced plates A, C, E and B, D interleaved one with the other to form a capacitor, the two sets of plates being movable relative to each other in a direction F which maintains constant the spacing between them, the shape and/or disposition of the plates being such that when an oscillating voltage V1, V2 is applied across the capacitor an output signal derived from an intermediate plate C varies with changes in the position of the two sets of plates. Such an arrangement gives an output which is substantially linearly dependent on displacement, and by attaching one set of plates to a spring it can be used as a force transducer, e.g. for weighing. <IMAGE>

Title: Silicone-polyimide copolymers, condensation vulcanizable compositions obtained therefrom, and methods for making
Inventor: RYANG HONG-SON
IPC: C07F7/08
Filed: 1984-10-17
Abstract: Silicone-polyimide copolymers having terminal silanol or silicon hydride radicals are provided based on the use of a norbornene terminated polyimide. A hydrosilation reaction is employed to introduce silicon-hydrogen into the terminal position of the polyimide having norbornene termination. The resulting hydrosilyl terminated polyimide is reacted with silanol terminated polydiorganosiloxane in the presence of a catalyst to produce silanol terminated polydiorganosiloxane-polyimide copolymer. Room temperature or low temperature condensation vulcanizable compositions based on the use of such silanol-terminated copolymers provide cured silicon-polyimide copolymers exhibiting improved toughness.
