Patent GB-2117789-A (GB)
Title: Abo blood grouping reagent
Inventor: LENNOX EDWIN SAMUEL
IPC: G01N33/80
Filed: 1983-02-25
Abstract: An ABO blood cell grouping reagent comprising, in admixture, one or more anti-A monoclonal antibodies and one or more anti-B monoclonal antibodies. An anti-A monoclonal antibody incorporates an anti-A, B monoclonal antibody, provided that the anti-A, B is potent enough to cause a macroscopic reaction with red blood cells possessing one or more A-type antigenic determinants. Similary, an anti-B monoclonal antibody incorporates an anti-A, B monoclonal antibody provided the anti-A, B is potent enough to cause a macroscopic reaction with red blood cells having one or more B-type antigens. Any mixture of monoclonal anti-A and anti-B antibodies that has sufficient agglutinating quality to give reliable results (for the presence of agglutinogens A and B) by the routine blood typing methods may be used. Preferably the monoclonal antibodies are derived from hybrid myelomas produced by the fusion of a parent cell line, especially NSI (abbreviated from P3-NS1/1-Ag 4-1) or NSO/1, with spleen or other immunocyte cells from mice immunised with human agglutinogen A or B or A, B. In one particularly preferred embodiment a monoclonal anti-A (6D4 or 3D3) and a monoclonal anti-b (NB1/19), derived respectively from the hybrid myeloma 6D4.12.3, A15 3D3.92.00 and NB1/19.112.28 are mixed. The present reagent may also contain a certain proportion of conventional Group O serum. The addition of this serum is to provide the present reagent with Ax activity especially of the monoclonal mixture lacks this activity. In a particularly preferred embodiment a one-third volume of Group O serum is added.

Title: Packaging tubes for electronic components
Inventor: LEE YUN KAI
IPC: H05K13/00
Filed: 1983-04-19
Abstract: An antistatic packaging tube containing electronic components (12), especially DIL encapsulated integrated circuits, and having a window 32 of transparent material along its length is so designed, co- relative to the shape of the packaged components (12), that the components (12) cannot come into contact with the material of the window 32. In this way the component 12 is less likely to be damaged by static electric charges on the window 32. There may be two such windows 32, 32a, Figs 8-11 (not shown), which strengthens the tube since the window material is stronger than the antistatic material of the rest of the tube. Preferably both clear and opaque antistatic materials are extruded together to form the tube, using apparatus with two or three main extruder screws (43, 43a, 44), Figs. 14-16 (not shown). <IMAGE>

The composition can also contain fungicides and/or insecticides if it is used for protecting wood.
Patent GB-2121350-A (GB)
Title: Composite foamed articles and process for their production
Inventor: BRADBURY JOHN ALBERT AVERY
IPC: B29C65/00
Filed: 1983-05-27
Abstract: Process for making composite foamed articles by impregnating an open-celled organic foam with an aqueous suspension of an insoluble solid impregnant to deposit the solid within the pores and then drying, using a closed mould system in which the foamed article is confined so that it seals with the walls of the mould and allows differential pressures to be built up across the thickness of the foam. These are used to assist impregnation, control degree of penetration of the impregnant, and drawing off excess liquid. Useful for making fire-resistant tiles from partly expanded polystyrene beads and can include surface-finishing and other steps. In one embodiment, a foam block (4) is moulded in a cavity defined by mould parts (1) and (2), the parts moved slightly apart, impregnating material (5) introduced into the space between the parts, and the parts reclosed to force the impregnating material partially or fully into the block. In another embodiment a second mould, not that used for forming the block, is used to effect impregnation. The second mould may or may not further shape the block. <IMAGE>

Title: Process and apparatus for purifying metal melts
Inventor: BUCSKY GYORGY
IPC: C21C7/072
Filed: 1983-06-24
Abstract: According to the invention flushing gases are fed into lower end (13) of a duct (2) containing static mixing element(s) and/or spin elements (3). In operation the duct is located in the melt, and so the duct contains molten metal. The duct may contain space-filling bodies and the metal melt is optionally caused to flow or the streaming velocity thereof is changed by means of the gas stream streaming through the duct (2) or by the static mixing elements and/or by means of an inductive heating current. In a modification molten metal flows continuously through the apparatus, which may have more than one duct. It is stated that efficient mixing of gas and metal is obtained without mechanical agitation. <IMAGE>

Title: Electric cord holder and cover
Inventor: POLLACK RONALD M
IPC: H02G3/04
Filed: 1982-11-19
Abstract: Electrical wiring forming the cords of domestic appliances such as clocks and lamps is unsightly and generally hangs or runs loosely from the appliances to the electrical outlets in a room. In order to hide such wiring and maintain it in an orderly condition, an electric cord holder and cover has been devised. The electric cord holder and cover (10) includes an elongated plastic extrusion of tubular shape which is a cross-section in the form of a substantially C-shaped front portion (11) and an overhang, and a rear portion (12) extending inwardly from one end of the C-shaped portion (11) towards the other end of the C-shaped portion, yet leaving a slot (17) adapted for insertion of electrical wiring between the inwardly extending rear portion (12) and the other end of said C-shaped portion (11), and a securing strip (14) of predetermined width which defines an outer surface. The securing strip (14) is connected to the rear portion (12) and is adapted to be attached to an external surface. The overhang extends outwardly up to the outer surface, so as to be flush therewith. The electric cord holder and cover (10) may then be attached to an external surface with the overhang abutting the external surface.

Title: Improvements in or relating to induction heating circuits for cooking appliances
Inventor: COPPIN JULIAN
IPC: H05B6/06
Filed: 1986-11-25
Abstract: A pan sensing circuit 7 responds to current flow through a pan heating coil L2 during periods when a GTO thyristor VT1, or a bipolar device, is non-conducting, the circuit 7 inhibiting a return of thyristor VT1 to conduction unless the sensed current indicates the presence of a suitable utensil. An interrogation circuit 11 allows turn on of thyristor VT1 at one second intervals until a suitable utensil is sensed. In normal operation thyristor VT1 is turned off when a current sensor 8 senses a rise in current to a predetermined level. Thyristor VT1 is turned on again when the current through the coil L2 reverses as sensed by a saturating current transformer T1 and a voltage detector 13. Pan sensor 7 detects the current through a freewheeling diode D1. A controller 9 sets the mark/space ratio of a generator 10 outside the limited range of power control obtainable by sensing current using circuit 8. Operation is inhibited if a protection circuit 12 senses an incorrect operating potential in any of circuits 6, 7, 8, 10, 11, 13. Circuit 12 also causes a predetermined powering-up sequence to be followed. A series ballast inductor L1 limits perk voltages, during resonance and also other optimisation of both the inductance and geometry of the pan coil L2. <IMAGE>
