Abstract: 1432289 Camouflage sheet or slab BARRACUDAVERKEN AB 25 Oct 1974 [1 Nov 1973] 46307/74 Heading F3X A method of manufacturing a camouflage sheet or slab bearing an overall camouflage pattern composed of a number of contiguous component patterns having the general outline of a 3-, 4-, 6-, or 8-sided figure and each coextensive with a respective zone of the sheet, wherein the individual component patterns present the same irregular pattern features and the overall pattern is built up by separately applying the pattern features to the respective zones of the sheet and arranging for the pattern features of the adjacent pairs of component patterns to be angularly offset relatively to one another by between 45 and 315 degrees. The zones may be square and the angular position disparity 90, 180 or 270 degrees. At least a partial pattern matching may be obtained. The edges of the zones and of the pattern elements are toothed and/or wavy and completely match each other in the seams between any two successive zones. The zones may be rectangles and have a mutual angular displacement of 180 degrees. The pattern may be applied by a pattern template of a silk screen device, printing plate or punching means, the pattern template and the sheet or slab being turned relative to one another to produce the required angular position disparity. Separate pattern positions may be joined together and/or attached to an underlayer. Fig. 2 shows a portion of a camouflage sheet which comprises four zones per row (1-4, Fig. 1) and Fig. 3 shows a single such zone. The patterns may be multi-coloured or single coloured, the latter having different graduations (darkness) for different pattern elements.

In a modification, Figs. 2A-2E (not shown), the aluminium plate is replaced by a steel plate apertured or recessed to receive the conductive member and also an integrated circuit. The adhesive layer is replaced by a polyimide film. The film may be copper coated, in which case the conductive member may be produced using a gold etch resist position using a negatively exposed photoresist. The conductive member may comprise several layers of conductor and polyimide to provide power planes, ground planes, &c. In another embodiment, Figs. 4A-4C (not shown) a solid material is applied over the conductive track to be crossed before the crossover is bonded in place.

An assembly head for automatic production lines and for introducing one workpiece into another, e.g. the spindle of a pedal into a corresponding rubber tread part, comprises a distribution member 2 which is pivoted at 3 between side arms on the head 1 having a holder 12 for attachment to a production line mechanism, and which is connected by a link 7 to an operating rod 6 which is vertically slidably accommodated in a groove 15 in the head 1 and has a bent-over upper end for operatively engaging a lug 13 carried by a punch 14 which works in a groove 21 in the head 1. The punch 14 is connected to the piston rod of an air cylinder motor 19 and when it is at the end of its downward stroke, as shown, it extends through the groove 15 and into an aligned bore 20 in the distributer 2. Upward movement of the punch 14 causes the lug 13 to lift the rod 7 so that the distributer is pivoted outwardly towards a shoot 18 supplied with workpieces, e.g. pedal treads 17, a stopping segment 4, carried by the distributer, being progressively moved out of the way of the lowermost workpiece 7 which, at the extreme outwardly pivoted position of the distributer 2, is aligned with the bore 20 and slides therein to rest against a resilient retainer 5. Downward movement of the punch 14 allows the spring 9 to return the rod 7 to its lower position, the distributer being pivoted to return to its original upright position and the punch 14 entering the bore 20 to eject the workpiece 7 on to a counterpiece placed below the distribution member 2. The stopping segment 4 at the same time moves into position to block the shoot 18. An adjustment screw 10 serves for accurately aligning the bore 20 with the punch.

Crack-free chromium is electro-deposited from a solution of trivalent chromium, ammonium and halide ions in a homogeneous liquid mixture of water and a liquid or a water-soluble dipolar organic compound containing a highly electronegative oxygen atom i. e. an oxygen atom activated by an adjacent electron-donating atom or group, the ratio by volume of water to dipolar organic compound being not greater than 60:40 and preferably not less than 20: 80. Specified dipolar organic compounds are dimethyl sulphoxide, tetrahydrothiophene dioxide (sulpholane), formamide, and alkyl and aryl carbonamides such as acetamide, N-methyl formamide and aprotic compounds such as dimethyl formamide, dimethyl acetamide and tetramethyl urea. The trivalent chromium may be added as the formale, acetate; oxalate, nitrate, sulphate or chrome alum but preferably is added as the hydrated chloride bromide or iodide. In examples the inorganic ions are provided by CrCl 3  6H 2  O, NaCl and NH 4  Cl together with H 3  BO 3  to give a pH of 1 to 3, and plating is effected at a temperature not exceeding 60‹C, with cell voltages of from 17 to 70 volts and C.C.D. of 1 to 20 amps/ sq. dm. In some cases the chromium deposit is covered with a green slime but this is readily removed by dipping in HC1. The cathode may be bright nickel plated copper and the anode is preferably of graphite, chromium or passivated lead anodes being less satisfactory. To avoid chlorine evolution the anode may be disposed in an anolyte of aqueous sodium or ammonium acetate separated from the plating electrolyte by a porous diaphragm, e.g. of porous ceramic.

Abstract: A preparation useful in the diagnosis of viral hepatitis comprises a physiologically acceptable suspension of antigenic components of active or inactivated human hepatitis virus obtained by extracting virus-containing material with diethyl ether or chloroform and subsequently evaporating the solvent.  Inactivated virus used may be obtained by culturing the virus on animal kidney tissue cells and inactivating the virus, e.g. by treatment with formalin.

Abstract: 1527517 Indicating apparatus; speedometers E DARZI 30 Nov 1976 [5 Dec 1975] 49980/75 Headings G1J and G1K The magnitude of a measured variable, e.g. a vehicle or shaft speed, is represented by the pitch of an audible tone, a reference tone or a series of different reference tones being sounded simultaneously with the variable tone or briefly interspersed with it. The variable tone may be produced by a siren mechanically driven, e.g. from a vehicle propellor shaft, with reference tones produced by horns, whistles, tuned reeds, or electronically when selected by the driver or operator. The variable may be displayed visually at the same time. In Fig. 1, a transducer such as a tacho-generator produces an A.C. electrical signal having a frequency proportional to the magnitude of the measured variable. An L.P. filter, e.g. cutting off frequencies above 300Hz, removes harmonics, and the filtered signal is passed to a frequency multiplier to increase the band width to e.g. 0-3000Hz, the signal being amplified and fed to a loud-speaker. An oscillator includes selector switches enabling a selected division or reference tone to be fed to the speaker, a repetitive contactor giving intermittent output of the selected tone. In a modification, Fig. 2 (not shown), a set of pass-band filters in parallel covers the range of input frequencies. Each filter has its own frequency modifier, comprising a subtracting unit and a frequency multiplier, to convert the respective frequency band into the full frequency range used by the speaker. Thus as the variable rises from zero to its maximum value, the audible tone rises across its full frequency range a number of times equal to the number of pass-band filters. A series of different variables to be monitored can be represented by signals, all connected to the same frequency range, which are sampled in turn by a time division multi-plexer and fed to a speaker. It can be arranged that the normal operating value of each variable is represented by the mid-range frequency of the speaker, the full range of the speaker representing e.g. Œ25% of the normal operating value of each variable.
