Title: Recorders for Recording Data
IPC: G07C1/10
Filed: 1982-01-19
Abstract: A time cost recorder enables entry and exit transactions to be recorded at will both by a badge bearing digitally encoded machine readable identity information and by a card bearing both digitally encoded machine readable identity information in the same recording medium and form as a badge and visible characters referring to the entry and exit transactions. Constant instructions for operation of the machine are stored in read-only memory, and a random-access memory includes locations severally allocatable to the badges and cards for recording the data relating to the entry and exit transactions of each badge or card according to the identity thereof. Thus badges are passed in the direction of arrow 4 through a combined reader and printer and cards are inserted in the direction of arrow 6 into a combined badge reader/printer that has a motor driven card transport roller that moves the card into and then out of the reader/printer. If the badges and cards carry the encoded information recorded on a magnetic stripe then correct insertion thereof may be tested for by attenuation of a reflected infra-red signal at the stripe. <IMAGE>

Title: Forming cartons
Inventor: OAKLEY JOHN RICHARD
IPC: B31B50/62
Filed: 1982-02-19
Abstract: In the forming of cartons, a water-based adhesive, e.g. an aqueous-dispersed polyvinylacetate, is applied as an atomised spray by guns (19, 20) to selected parts (23, 27) of a carbon blank (17) of uncoated board and partially dried by hot gas (air) jets (29), and the carton is erected by forcing the carton blank by a punch (34) through a forming die so that the selected parts are pressed briefly against cooperating parts of the erected blank to secure them together, by means of projections (36) on the punch and pressure members (37) forming part of the die. The atomised spraying followed by hot air drying of the adhesive enables adhesion to be effected by very brief pressure, and the method can thus be used for high speed production of cartons of uncoated board. <IMAGE>
Patent GB-2104698-A (GB)
Title: An improved apparatus for signature verification
Inventor: PARKS JOHN RONALD
IPC: G06V30/194
Filed: 1982-04-26
Abstract: Real-time signature verification uses a transducer pad in which the pressure of a stylus causes contact to be made between two resistive films. Such a transducer is energised by current pulses to sample pairs of X and Y co-ordinates 114, every 5 milliseconds. The analogue voltage outputs are converted to digital form and processed under the control of a microprocessor to determine, 115, numerical parameters each representing a significant feature of the signature. A set of specimen signatures is collected and from these the mean values and standard deviations of several relevant parameters are calculated and committed to memory 61-65, 69, 70, each standard deviation being modified, 64, 65, by the standard deviation of the population at large. The parameters for a working signature are compared, 117, with the respective stored mean values for the individual concerned. Each deviation from a stored mean value is compared with the corresponding stored standard deviation in a non-linear scoring circuit. The aggregate score derived from the comparison of several parameters is compared with a preset threshold level to decide whether or not a working signature is genuine. The specification describes a number of refinements which result in improved performance compared with earlier embodiments. <IMAGE>

Patent GB-2132466-A (GB)
Title: Whey product and method for obtaining same
Inventor: COLLINS MARY E
IPC: A23K10/28
Filed: 1982-12-22
Abstract: This invention provides a food product for use as a nutritional supplement for animals, which is prepared by introducing into the udders of prepartum cows or other ungulates a specific antigen-like material, removing milk and colostrum from said ungulate, extracting whey from these fluids and removing large molecules from the whey to give a product with an active fraction with a molecular weight on the order of 1200 or less. The antigen-like material is selected from a group consisting of pollen, bacteria, virus, mould allergens, blood from sick animals, sperm and toxins. In a preferred form of the invention the whey may be extracted by separating the fat from the fluids, freezing the fluids and gradually thawing them. Next the clear whey so produced is removed from the slurry, which is also formed, by siphoning. Then the curd milk solids in the slurry are coagulated by a combination of heating and acidification. Finally the curd solids are removed and the remaining whey is combined with the aforementioned clear whey, and the combined solutions of whey are passed through a filter having a size of not greater than 0.2 rim to give the product.

Patent GB-2152322-A (GB)
Title: Signal generator
Inventor: ALNER PHILLIP
IPC: H04N9/74
Filed: 1983-11-30
Abstract: A signal generator system useful for providing a simulated FLIR display for a flight simulator uses a gated full colour TV image signal of a scene with a chroma-key. Objects to appear 'hot' in the FLIR simulation are coloured and hence gated out of the scene by the chroma-key to be replaced by an appropriate hot FLIR colour in a monochrome display. To provide the background a monochrome display of inverse green is suitable, with added noise on which the hot objects appear white. With an inverse green background, objects to appear hot are coloured orange. Normal full colour display can be shown by using the same chroma-key discrimination and replacing the orange colours with an appropriate camouflage colour. <IMAGE>
Patent GB-2133123-A (GB)
Title: Hand grinder and valve therefor
Inventor: HUNDEBOL KELD OTTING
IPC: F16K1/12
Filed: 1983-12-08
Abstract: The air or liquid is supplied to a grinder through a handle with a built-in valve. By turning the handle (1) the valve opens or closes. The valve body itself (7,9) is secured to a stay in the form of a bolt (10) and a pipe (8) screwed into the bottom of the handle casing (1), whereas the valve seat (14) is formed as a recess in a bush (2) being stationary relative to the casing. The handle has an oblique track (4) wherein a bolt (3) secured in the bush moves the casing (1) and thereby the valve body relative to the bush (2) when the handle is turned. When the handle is released in the open position of the valve (Figure 3) (not shown), the pressure exerted by the medium will move the casing so as to close the valve since the area of the casing is larger than that of the bush (2). The machine can thereby be safely and reliably disconnected by releasing the hold on the handle. The valve can be used for a hand grinder with a U-shaped handle pipe with handle ends and a hollow spindle situated between the handle ends, an air machine being arranged in the spindle. The spindle has a number of slotted grinding discs, and a pressure medium is admitted to the machine through passages in the handle pipe. <IMAGE>
