Title: Laser having a Stabilised Output Spectrum.
Inventor: FORSTER DONALD CHARLES
IPC: H01S3/139
Filed: 1968-04-04
Abstract: 1,158,990. Lasers. HUGHES AIRCRAFT CO. 4 April, 1968 [28 April, 1967],No. 16262/68. Heading H1C. The output 23 of a laser 11 is frequency stabilized by combining an output sample with the frequency-modulated but otherwise stabilized output 41 of a second laser 33, the combined outputs being detected by a photodetector 63 which generates heat pulses at the times when the sample and frequency-modulated outputs are of the same frequency, which pulses are used to gate an amplifier 55 and so control the resonator length of laser 11. As shown in Fig. 1, laser 11 comprises an active medium 13 and partially transmissive mirrors 17, 19 of which mirror 19 is axially displaceable by an apertured piezo-electric body 21. Laser 33 is similar, and is controlled in known manner to produce a frequency modulated but otherwise stabilized output by using a dither oscillator 49 to vibrate resonator mirror 37, the mean position of the mirror being determined by a circuit comprising a photo-detector 43, amplifiers 45, 57, a phase detector 47 and an adder 53 for combining the output error signal with that of the dither oscillator. To frequency stabilize laser 11, the combined outputs detected by 63 produce zero-frequency-difference heat pulses which pass through a low-pass amplifier 67 and gate an amplifier 55 coupled to the dither oscillator. The output of the amplifier 55 is an error signal in pulse form, which is smoothed to a D.C. signal by an R-C combination 71, 73, and further amplified at 75 before application to the resonator piezo-electric transducer 21. Laser active media may be argon, helium-neon or xenon.

Title: Improvements in process of treating palladium and product of such process
IPC: B01J23/40
Filed: 1936-06-11
Abstract: Palladium in a form particularly suitable for catalytic use is obtained by treating small pieces of metal including balls of wire, flakes or rolls of foil, by cleaning the surface and repeated sorption of hydrogen at below 70 DEG  C. and its discharge by thermic disassociation.  The product may also be used for boiling spheres, pen nib points and for jewellery, as for example, bracelets, necklets and other articles, in some instances coloured superficially as by anodic oxidation or by heating in air. Although the sorption may be in an electrolytic cell, it is preferably from gaseous hydrogen, and the discharge effected by direct combustion on the metal.  The effect of repeated sorption and discharge is to make the pieces, bales and rolls approximate to a spherical shape, and the flakes to wrinkle up without cracking.  The product may be used alone or as a carrier for palladium black or other catalyst.  Other metals or metalloids such as gold, silver, copper, osmium, ruthenium, nickel, cobalt, silicon, boron, zirconium, &c., may be incorporated by embedding the palladium body in a powdered mass of the material or electroplating it and heating at 600 to 1200 DEG  C. in a reducing atmosphere, or by impregnating with salts, reducing and heating.ALSO:Palladium in a form particularly suitable for catalytic use is obtained by treating small pieces of metal, including balls of wire, flakes or rolls of foil, by cleaning the surface and repeated sorption of hydrogen at below 70 DEG  C. and its discharge by thermic disassociation.

Title: Improvements in or relating to coin counting and wrapping machines
IPC: G07D9/06
Filed: 1967-04-10
Abstract: 1,133,699. Coin counting and wrapping machines. I. UCHIDA. 10 April, 1967 [3 Nov., 1966], No. 16344/67. Heading B8C. Coin wrapping and counting apparatus of the kind forming a stack and then wrapping it, includes means whereby coins of an incomplete stack may be discharged before wrapping and the machine at the same time be reset for the next operation. The coin feeding and wrapping apparatus are of known kinds the latter being as described in U.S. Specification 3,037,336. Coins are projected centrifugally from a rotating disc 1 against an adjustable guide 3, a gap between disc and guide permitting undersized coins to fall clear. The coins are fed through a gate 2 by a roller 13, the gate excluding over-sized coins, to a shoot 53 leading to the stacking cylinder 50, Fig. 11. The latter includes hinged halves 50a, 50b which open to permit removal of the stack by arms 133 (one only shown) for wrapping. The machine shown forms stacks of fifty coins, a counting wheel 4 being rotated by their passage through the gate and operating a counter 9 through gearing 6, 7. The shaft of the wheel carries a pinion 10, Fig. 5, which, through an idler 11, rotates a gear 12 having fifty teeth and an aperture 17 which receives a locking lug (19a), Fig. 4 (not shown) once per revolution, e.g. once per wrapping operation. In the event that the mass of coins distributed by the disc 1 is not a multiple of fifty, the odd coins form an incomplete stack. The operator presses a contact which engages a solenoid 140 to withdraw a shutter 135 from beneath the base of the cylinder 50 and allow the coins to fall through. At the same time a motor is started to rotate a cam-shaft 90. One cam 103 pivots a lever 110 through associated linkage to clear the idler 11 from the pinion 10 and gear 12 to free the latter. A further cam disc 113 causes a lever 120 to engage an ovoid cam 122 on the shaft of the gear 12 to return it to the start position. Another cam 91 permits the lug (19a) to enter the aperture 17 in the gear to lock it in this position. A face cam (97), Fig. 10 (not shown), on a shaft driven by the shaft 90 zeroizes the counter and after one revolution of this shaft, the motor is stopped.

Abstract: 1,269,072. DIR hydroquinones in photographic silver halide materials. EASTMAN KODAK CO. April 1, 1969 [April 1, 1968], No. 16868/69. Heading G2C. A photographic material comprises a support carrying at least two superposed silver halide layers sensitive to different spectral regions or separated by a filter layer whereby each layer is adapted to be separately imagewise exposed and the silver halide emulsion layer or layers not contiguous to the support contains a development inhibitor releasing (DIR) hydroquinone compound (which is a non-diffusible, heterocyclic thiosubstituted hydroquinone which reacts with oxidized colour developing agent to form a diffusible mercaptan development inhibitor) and has a finer grain silver halide emulsion than that of the emulsion contiguous to the support, and at least one of the silver halide emulsion layers contains a non-diffusing, dye-forming coupler. All the silver halide emulsion layers may contain non-diffusing dye-forming couplers, the coupler in each layer forming a different colour dye from those in any of the other layers. Many colour couplers are specified. The DIR compound preferably has the formula:- wherein Q and Q<SP>1</SP> are each H or an alkaline splittable masking group, -S-Rad is a monothio radical which is split when the compound crossoxidizes with oxidized colour developer, Rad is a photographically inert diffusible carbon containing heterocyclic radical, Ball is a photographically inert, organic radical which renders the compound non-diffusing, Q<SP>2</SP> is H, sulphonyl, carboxyl or an alkali metal salt thereof and Q<SP>3</SP> and Q<SP>4</SP> which may be the same or different each represent H, or alkyl of up to 10 carbons. Preferably there are two silver halide emulsion layers - a silver chlorobromide emulsion containing the DIR compound and a silver bromoiodide emulsion. One emulsion may be green-sensitized and the other is preferably unsensitized which embodiment gives a black and a coloured image (see EX2). The filter layer is preferably bleached during photographic processing, and may be a layer of yellow Carey-Lea silver (see EX7). There may be a hydrophilic colloid layer between each silver halide emulsion layer to delay diffusion of the photographic processing solutions. Examples 12 and 13 relate to the diffusible dye transfer process using materials of this invention. These materials are useful in aerial reconnaissance. The DIR hydroquinone compounds can also be used in interlayers to produce a uniform increase in sharpness of each of the dye images, since these DIR compounds are colourless and do not form dyes.
