As shown the display comprises seven-segment type flourescent tubes, the grids G and anode segments S of which are controlled by a driver circuit 9. The driver circuit and the tube filaments F<SP>1</SP> are supplied from a voltage converter 5 which is energized only when the switch 2 is on contact ST for normal vehicle running. A voltage stabilizer 3 is supplied continuously from the battery and feeds the circuitry 100 which is in<SI form and counts the output of a crystal oscillator 6. A switch 10 permits setting. The circuitry 100 comprises frequency divider 101, Fig. 4, feeding seconds, minutes, and hours counters 102-104 via successive gates 105-107, and a seven-segment decoder (116), Fig. 3 (not shown) to drive the display. The switch 10 has a normal run position T, a hold position H in which the gate 105 is disabled so that the existing counts are held in the counters, slow and fast time setting positions S and F, and a reset position R in which all the counters are reset to zero. In the setting positions S, F the 1 c/s output from divider 101 is fed to the minutes counter 103 or hours counter 104 respectively. The clock can thus also be used as an elapsed time indicator, e.g. to integrate time over several stages of a rally, and can count in seconds and minutes instead of in minutes and hours. A number of other setting arrangements of the switch 10 and gating circuitry are described Figs. 5-8 (not shown), and the use of other types of display is envisaged.

Abstract: 1363653 Obtaining fibres and spinning yarns LAMBEG INDUSTRIAL RESEARCH ASSOCIATION 19 Oct 1971 [20 Oct 1970] 49635/ 70 Heading DIF In a process for obtaining flax fibres from the harvested plant and preparing the fibres for wet or dry spinning into linen yarns, the partially dried, unwetted straw is fed through a decorticating machine e.g. a turbine switcher, to remove the wood and yield green fibres which are formed into sliver e.g. by an automatic spreader as in a goods machine. The sliver is chemically treated at least partially to remove bonding material associated with the fibres, followed by drying, mechanical softening, as by means of fluted rollers and beaters or by crimping, and (stretch) breaking the fibres of the sliver to (staple) lengths of about 10 inches. If a blended yarn is required, other e.g. synthetic, fibres are doubled into the sliver over a creel at the feed end of the breaking machine. The chemical treatment may comprise one-or two-stage boiling in at least one alkali e.g. sodium carbonate or hydroxide, solution, followed by scouring in formic acid, washing and further boiling in alkali solution; a fibre finish such as a cationic surface active agent imparting lubricating and softening properties may be applied; excess liquid is removed as by mangling, suction or centrifuging and hot air. The final sliver is passed successively through precomb doubling and combing machines and then converted to yarn by line or tow or like conventional system.

Title: Tone reproduction in graphic arts process simulator

Filed: 1972-11-01
Abstract: 1367564 Printing process simulator HAZELTINE CORP 1 Nov 1972 [16 March 1972] 50257/72 Heading H4F Relates to an improvement in the colour printing process simulation system of Specification 1,319,686 which compensates for proportionality failure in which light tones in the simulated CRT displayed image appear lighter than the actual colour print, and for additivity failure in which dark tones in the simulated CRT displayed image appear darker than the actual colour print. Proportionality failure may be compensated by producing apparent, rather than the actual, dot area signals C, Y, and M, this being effected by modifying the actual dot area signals by an appropriate non-linear characteristic, e.g. of an exponential amplifier (51, Fig. 2, not shown) or by adjusting the characteristic of the ink spread simulator (25). Additivity failure may be compensated by including in the processing of these apparent dot area signals (which processing is in accordance with a set of mathematical relationships, e.g. linear Neugebauer equations, to develop a group of signals Ac, Ay, Am &c. representative of the fractional dot area in the actual colour print), at least one term containing a selected exponential term, e.g. one or more terms in the equations may be modified by selected fractional exponents. Such as friactional exponent may be implemented by modifying an apparent dot area signal supplied by the proportionality failure exponential amplifier (51) by an additional exponential amplifier (52, Fig. 2, not shown), or by including a voltage divider (53, 54, Fig. 3, not shown) between a log amplifier (28a) and a log adder (29b) in the Neugebauer equation processor. Similar modifications to simulate proportionality and additivity failure may be included in the simulation system of U.S.A. Specification 3,128,333.

Abstract: 1464936 Edge sealing of plastics laminates in packaging ZIRISTOR AB 28 Nov 1974 [5 Dec 1973] 51580/74 Heading B8C A tube is formed, in the course of packaging operations, by the overlap sealing of opposite edge zones of a web of laminate packaging material 8, 9, 10 incorporating coating layers 9, 10 of heat-sealable plastics material, oversealing the edges of the web exposed internally of the tube, and applying heat to the interior of the tube in the course of sterilization, the said inner edge of the web being over-sealed by a strip of material 11 which is heat-sealable to the coating layer 9 of the web inside the tube and which is substantially inextensible, or extensible only to a small degree, at the temperature applied by heat in the said course of sterilization. The laminate packaging material consists of a base 8 of paper, or cardbaord, which is coated with a polyethylene material 9, 10, the sealing strip 11 comprising a base layer made of a material 12, e.g. polyamide, or aluminium foil, which has a higher softening temperature than that of the polyethylene material 9, 10 and which is coated, on both sides, with a material, e.g. polyethylene, which can be sealed to the web coating 9. After a tube has been formed it is brought into contact with a sterilization liquid, e.g. hydrogen peroxide, and the latter is evaporated by introducing air, at a very high temperature, into the tube. Despite cooling of the tube from the exterior, overheating at the thickened joint is not prevented and evaporation of the 6% moisture content in the paper layer 8 at the joint, particularly at the web edge, forms a vapour pressure beneath the covering strip 11. During this process the laminated strip 11, with the particular base layer 12, e.g. of polyamide, or aluminium foil, does not deform under the action of the heat and vapour pressure so that the cut, inner edge of the laminated web material always remains completely covered. One side of the strip 11 may be affixed to the coating 9 to project from one edge of the web before the tube is formed. A package, Fig. 1, is formed from a tube and has folded-down, and sealed, lugs 6, 7.
