Patent GB-2173638-A (GB)
Title: Semiconductor devices
Inventor: SCOVELL PETER DENIS
IPC: H01L27/06
Filed: 1986-02-11
Abstract: A bipolar transistor structure (1) which can be used in an integrated circuit where bipolar (1) and CMOS transistors (2, 3) are formed simultaneously on one substrate. In integrated circuit form the material, for example polycrystalline silicon, used for the gates (11, 21) of the CMOS transistors is also used for the emitters (29) of the bipolar transistors, the collectors of the bipolar devices are comprised by doped wells (5) in the substrate (4) and the base contacts of the bipolar devices are comprised by regions (27, 27a) equivalent to source and drain regions (17, 18) of the n-well MOS transistors and bridged by base implants (28). The conventional CMOS processing is modified by the addition of two masking steps and one implant (baseimplant). One masking step defines the area for the base implant (28) and the other masking step defines an area of the oxide (30) over the base implant which must be removed to allow contact between the polycrystalline silicon (29), which is suitably doped to provide the emitter, and the base (27, 27a, 28). The base contacts are produced in a semi-self-aligned manner.

Title: Monoclonal antibodies and antigen for human non-small cell lung carcinomas
Inventor: HELLSTROM INGEGERD
IPC: C12N15/00
Filed: 1985-12-13
Abstract: The present invention is concerned with novel monoclonal antibodies which define a glycolipid antigen associated with human non-small cell lung carcinomas ("NSCLC") and certain other human carcinomas. The antibodies bind to normal human cells to a much lesser degree than to tumor cells.

Title: Cyclone separators
Inventor: HUMADI ABDOUL AMIR ALI
IPC: B04C7/00
Filed: 1987-04-10
Abstract: A cyclone separator 10 includes a central core 12 having a closed bottom end 14 and an upper end leading to a gas exit port 16. Surrounding the core 12 is a helical surface 20 enclosed by a cylindrical vessel 22 to define a helical pathway leading from a tangential gas entry port 24 to a communicating passage 18 leading to the central core 12.

Patent GB-2211383-A (GB)
Title: Raceway culturing of fish
Inventor: LONG CLIFFORD W
IPC: A01K61/60
Filed: 1989-01-10
Abstract: Fish are cultured in one or more flumelike watercourses, bounded by a raceway (10) or a plurality of raceways (110A-E). The rate of water flow is such that the fish swim substantially continuously to maintain position, and the fish are so numerous that they are too close together to assert territorial rights. Water is preferably supplied from and returned to a surrounding natural or man-made body of water, which also preferably floats the physical raceway apparatus, enabling water depth adjustment. Water enters via a well enclosure (11, 111) at the upstream end, as by upwelling, passes through the watercourse, sweeping waste materials along, and leaves via a weir-like enclosure (19, 119) at the downstream end, within which such waste is collected. Fish so cultured survive well and grow rapidly and uniformly.

Title: Variable transmission optical glasses
Inventor: MASON HOWARD LEONARD
IPC: G02C7/12
Filed: 1990-01-20
Abstract: A pair of optical glasses, with each lens containing two polarising filters, one of which is rotatable; the other being fixed. The wearer can rotate the rotatable filters with respect to the fixed filters, thus cross-polarising them and varying the transmission ratio. The rotatable filters may have teeth on the perimeter making it possible to mesh these to ensure that the filters rotate through equal angles. This ensures that the transmission coefficient varies equally in both lenses. To get the frames the correct size and aspect ratio, the filters may either be directly meshed or have intermediate idler wheel(s). <IMAGE>

Filed: 1990-03-09
Abstract: An animal pen (10), which is particularly useful for fostering orphaned livestock onto a potential foster mother, has peripheral walls (14, 16, 18 and 20) around a floor (12). One wall (20) has a headgate (28) formed by a pair of inwardly opening gates (30, 30'). When the gates (30, 30') are closed, they define a central slot (36) dimensioned to receive the neck of (e.g) a ewe to restrain her but without causing distress. Opposite walls have sets of slots (40, 42, 44 and 46), mutually in register. Bars (48, 50) are provided for passing between and connecting equivalent slots in opposite walls. When in position, the bars (48, 50) partition the pen into compartments. The height of the bars is selected, such that the ewe is restrained in one compartment, but the orphan lambs have free access to all parts of the pen (10). <IMAGE>
Patent GB-2231512-A (GB)
Title: Dense media
Inventor: SERGEANT PETER JAMES
IPC: B01F11/02
Filed: 1990-04-23
Abstract: A dense medium for use in a dense medium separation process comprises an emulsion of a molten metal alloy in a liquid carrier, e.g. water. The medium may be used in this form by maintaining its temperature above the melting point of the metal alloy. Alternatively, the medium may be cooled to allow the metal alloy to solidify; the medium may then be used in the form of a suspension of the alloy particles. The medium is prepared by adding the metal alloy in solid form to the liquid carrier, heating the carrier to above the melting point of the alloy, applying ultrasonic vibrations to disperse the molten alloy in fine droplets in the carrier liquid, and pumping the dispersion around a circuit to form and maintain the emulsion.
