Abstract: An anhydride-cured epoxy resin (epoxy resin plus anhydride curing agent plus catalyst) may be fortified (i.e. increased in strength and modulus without being made brittle) by the addition of a fortifying agent comprising a mixture of a carboxylic acid and the reaction product of a carboxylic acid anhydride and a substituted aromatic amine.

Abstract: A novel technique is disclosed for the immobilization of plant cells on a support. The cells are deposited on a surface of fibrous support which provides for strong binding of plant tissue biomass growing in the submerged culture. Specifically the plant cells are immobilised onto the surface of a fibrous support comprising a multiplicity of loosely bound polyester and/or cellulosic fibres by simple contact of the support with a suspension of the plant cells in a culture medium.

Abstract: A method for the continuous production of a purified immunoglobulin preparation wherein the antibodies are substantially enriched by means of a selective two-step ammonium sulfate fractionation procedure employing centrifugation and ion depletion processes. The purified immunoglobulins are subsequently commingled with condensed skim milk and spray dried. The resulting product for example is employed in the formulation of milk replacers for artificial rearing of neonatal pigs to provide the passive immunity to disease normally provided by sows' colostrum and later milk.

Abstract: A method of, and apparatus for, encoding and decoding a sequence of data bytes to permit correction of bit errors occurring in one byte of the sequence, or two bytes providing that the two incorrect bytes can be identified (for example if the bytes show parity failure). Each data byte of the sequence comprises data bits and one parity check bit. To encode the sequence of data bytes two «Code C " code bytes are determined from the data bytes, according to predetermined relationships, the data bytes and code bytes together forming an encoded data block. Also, there is provided a method of, and apparatus for, encoding and decoding a bundle of data blocks to permit correction of a number bit errors occurring in bytes of the bundle. (Conceptually, the bundle of data blocks comprises a stack of data blocks, one positioned under another to form a two dimensional array of bytes.) Data block bundle encoding consists of separately encoding rows (i.e. horizontal encoding) and columns or pairs of colums (i.e. vertical encoding) of bytes of the bundle array with two «Code C» code bytes.

Abstract: The specification discloses a method and apparatus for concentration of vapours present in trace quantities in the atmosphere in a continuous and rapid manner. It relates especially to a device to enhance the concentration of trace vapours to such a level that they may be more readily analyzed by appropriate instrumentation. This is of considerable value in connection with the detection of certain vapours which are associated with explosive devices and bombs. These are of considerable importance now in connection with security at airports and the like. The specification discloses a method and apparatus for the continuous concentration of trace gases in a gaseous medium, such as air, comprising the steps of bringing the air into intimate contact with a suitable free-flowing adsorption powder in an adsorption region (13), passing the air containing the treated powder and adsorbed vapours through a cyclone separator (12) to produce a substantially power-free air stream and a powder containing adsorbed vapours, then passing the powder through a desorption region (40) whereby the powder carrying trace vapours is heated in a heating zone (45, 46) in the presence of a carrier stream at a temperature sufficient to release the adsorbed trace vapours of interest, and thus to produce a vapour- enriched carrier gas stream. The powder is then normally recycled into the air inlet stream (10).

Abstract: A small linearly polarized adaptive array antenna for communication systems is disclosed. The antenna includes a driven λ/4 monopole (1) on a ground plane (3) at the center of concentric circles on which a plurality of linear coaxial parasitic elements (2) are arranged in an array pattern. Switches control bias voltages to solid state diodes to activate certain parasitic elements (2) so that the radiation pattern can be altered for the optimum operation.

Abstract: A hard to simulate, readily distinguishable from counterfeits, optical interference authenticating device comprises a substrate, and at least one optical interference, form depicting coating on the substrate and partially covering the substrate to delineate a known, distinct and readily distinguishable form thereon. The said at least one optical interference coating comprises at least one optical interference layer having known spectral reflectance and spectral transmittance characteristics when viewed at at least one particular angle so that the form is visible in particular colouration at the or each said particular angle of incidence of light thereon by reflected or transmitted light. At least one other optical interference coating may be provided on the substrate and may completely cover one side of it and the substrate may be transparent, semi-transparent or opaque, depending how the spectral characteristics are to be observed. A marginal edge portion of the form depicting coating may taper in thickness to provide a multi-coloured auriole around the form. When a plurality of form depicting coatings are provided they may partially overlie one another to provide a more complex pattern.
