Title: Bags
IPC: B65D33/34
Filed: 1979-08-10
Abstract: A security bag is formed from a single sheet of polyethylene folded over so that one section is longer than the other. The adjoining edges (12, 14) are seam-welded and the overhanging section forms a flap (18). An adhesive which forms a very strong bond with the plastics material is applied by peelable strips close to the edge (16) of the front panel (14) and close to the flap edge (18). The adhesive is chosen so as to have a bond between itself and the material greater than the breaking strength or at least stretching strength of the material. Alternatively, a weakened region in the form of a line of perforations (30) is formed either in the material forming the front panel (24) or the material in the region of the fold (20). <IMAGE>

Title: Radioimmunoassay of a Cardioactive Glycoside
IPC: G01N33/534
Filed: 1980-03-21
Abstract: There is a problem in the radioimmunoassay of the active metabolite in human beings of pentaacetylgitoxin, viz. 16- acetylgitoxin, which problem arises because this metabolite is metabolised by the usual experimental animals which are used to produce the antibodies required for the assay. There is provided the required antibody by administering to the experimental animal a conjugate of 16-acetylgitoxin and a protein (preferably bovine serum albumen) protecting its 16-acetyl group from decomposition by the animal organism. Also provided is a test substance for use in the assay, the effective component being a radioactively-marked, preferably tritium-marked, compound which is chemically very similar, or identical, to 16-acetylgitoxin.

Patent GB-2061340-A (GB)
Title: Method and apparatus for continuously S-Z stranding electrical cable cores
IPC: D07B3/00
Filed: 1980-05-29
Abstract: The invention is concerned with a continuous cable core stranding technique, wherein thick cable cores are concentrated into a bundle or bunch at a first stranding point, and hauled off therefrom by one or more gripping jaw or tong haul-off assemblies, which rotate about the bundle axis to S-Z strand the cores and which retain the stranded material in a torsion free state over a predetermined distance. From these retaining means, the material is advanced to a second stranding point. According to the invention, the interval (l) between the end of the retaining means and the second stranding point is an even-number multiple of (i.e. at least twice) the storage length, the latter being the distance lsp from the beginning to the end of the one or more haul-off assemblies mentioned above. This measure makes it possible to minimise "waviness" in the cable core bundle or bunch. The cores concentrated into a bundle or bunch at the first stranding point may, immediately after leaving the latter, be wrapped with one or more retaining helices, whereby deviations of the stranded elements from their desired positions in the stranded assembly may be minimised, even with stranding elements of large cross-section. <IMAGE>

Title: Separation of mixtures of solids and liquids
IPC: B04B1/00
Filed: 1980-06-13
Abstract: Oil palm sludge effluent is fed into a drum (6) which is continuously rotated about its horizontal axis. Solids collect on the imperforate cylindrical drum wall and liquids escape through screened apertures (26, 32) in the drum end walls, one (10) of which is centrally apertured for introduction of the effluent and removal of the solids, the other (8) being connected to a shaft (12) by which the drum is rotated. When liquid in the vessel in which the drum is contained reaches a predetermined level, electric control equipment effects movement of a scraper blade (58) towards the cylindrical wall to scoop the solids into a hopper which guides them out of the drum, and the effluent supply is stopped. When the blade reaches an end position, close to the drum wall, it is returned and the effluent supply is resumed. <IMAGE>

Title: Reducing cross-colour in colour television decoding apparatus
Inventor: GALE TIMOTHY KEVIN
IPC: H04N9/64
Filed: 1982-05-06
Abstract: A discriminator circuit to reduce the effects of errors in the separation of luminous from chrominance, in a colour television decoder comprises a bandpass filter (1) which is driven by the separated luminance signal and is centred at the colour subcarrier frequency, an envelope detector (2), filter (3), and a non-linear transfer circuit (4). The low frequency, conditioned luminance signal is applied to one input of each of two multipliers (5 and 6) which are inserted in the colour difference paths. The delay introduced by the elements (1) to (4) is compensated for in the colour difference paths by the delay lines (7 and 8) and in the luminance path by the delay line (9). The effect of the circuit is to attenuate the colour difference signals when a significant amount of high frequency information is present at the colour subcarrier frequency and which is therefore present in the chrominance channels. <IMAGE>

Title: Aligning and focussing optical systems
Inventor: HORNING KLAUS
IPC: G02B27/40
Filed: 1983-09-28
Abstract: Light from the objective 1 of the optical system, particularly an astronomical telescope, passes through a rotating beam deflecting device 4 and is nominally focussed onto a sectorial diaphragm 2. The diaphragm 2 consists of four quadrants, two opaque and two transparent (Fig. 2). Light passing through the diaphragm 2 is then focussed 9 onto a photosensor 10. Alignment is determined by comparing the amounts of light falling on the four quadrants of the diaphragm; focussing is determined by calculating the standard deviation of the image by means of analysing the light arriving at the sensor 10 as the image sweeps across the opaque/transparent boundary of the sectorial diaphragm 2. All this is done by analysing the output of the sensor 10 in, e.g. a computer. <IMAGE>
