Title: Test to determine antigens or antibodies in unknown samples - using a heterological system and labelled antigens or antibodies from a second animal or man
IPC: G01N33/576
Filed: 1975-07-09
Abstract: Determination of the presence of antigens or their anti-bodies in unknown samples using a heterological system of antigens or their antibodies, consisting of: (a) contacting the unknown sample with an antigen or antibody coated on a test object to give a layer of antigen or its antibody obtd. from a first animal species; (b) initial incubation of the unknown sample while in contact with the layer; (c) removal of the unknown sample from the test object and the vessel which tonatin a layer of the antigen or its antibody; (d) contacting the layer with a substance to which an indicator or labelling agent is bound, this material consists of the antigen or its antibody, provided that when the layer consists of antigen, the labelled material is also an antigen but obtd. from a second animal species; (e) second incubation of the layer in contact with the labelled material; and (f) examination of the test object and vessel on the presence of labelled material to determine the presence of antigen or its antibody in the unknown sample. The test may be used on all systems which can utilise a 2-phase antigen- or anti-body system such as antigens with two or more reactive sites or systems which can utilise a 2-phase antibody reaction. Pref. use is to measure heptatitis-associated antigen levels in serum. The test largely prevents cross-reactions in immunological procedures, giving more realistic results.

Title: Flying shears tool guide slide - has overlap gear between basic drive and transport rollers
IPC: B23D36/00
Filed: 1975-09-18
Abstract: The synchronised control device is for tool guide slides which move backwards and forwards for flying shears or punching machines for machining or working a strip of material fed by advance feed rollers. The slide movement is achieved via a curve disc, crankshaft or tow crank which at the same time operates the feed rollers. The movement of the slide is such that its speed over a determined area is the same as that of the material strip, but for the rest of its travel moves at kinematic produced speed. Between the basic drive and the transport rollers, but after a junction point for the slide drive, an overlap gear is arranged, which imparts additionally a positive or negative speed to the transport rollers in the non-synchronisation phase between the slide and the transport rollers.

The said groups are obtained by reduction of -OCF 2 CF 2 SO 3 X groups (see Division C3), and the membrane may contain residual groups of this type. Preferred membranes contain -OCF 2 COOM groups on one surface, which faces the cathode, and -OCF 2 CF 2 SO 3 M groups on the opposite surface. The membrane may be formed from a single film, or may be a composite of two polymeric films, and in either case it may further include a reinforcing layer, e.g. a fabric formed from PTFE fibres. The 27 specific examples describe a variety of such membranes and their application in the electrolysis of brine, the starting copolymers being of tetrafluoroethylene and perfluoro (3, 6-dioxa- 4-methyl-7-octene sulphonyl fluoride, in some cases with a further monomer which is hexafluoropropene, perfluoropropyl vinyl ether or perfluoro- 3, 6-dioxa-5-methyl-nonene-1.

Title: Lens hood for laser beam objectives - prevents deposition of evaporated materials on the front surface of the objective
IPC: G02B7/00
Filed: 1977-04-27
Abstract: Adaptor for reducing the amt. of material vapour deposited on and dirtying an objective used for beam focussing is claimed, esp. during microspectral analysis using a laser beam or in the laser machining of materials.
