Title: Improvements in and relating to the production of light sensitive printing papers
IPC: G03C1/64
Filed: 1936-12-04
Abstract: 491,586. Photographic blue -print processes. HALDEN & CO., Ltd., J., and HOLDEN, J. Dec. 4, 1936, No. 33273. [Class 98 (ii)] Blue-print papers are made by coating the paper with a solution of a ferric salt, a ferrocyanide with or without a ferricyanide and a suitable buffer salt in neutral or alkaline condition, drying the paper, and applying a fixing agent before or after exposure to light to render the ferrocyanide or ferricyanide insoluble when the paper is developed by aqueous contact. .The buffer salt inhibits the formation of the insoluble Prussian blue, due to the presence of the ferric salt and the ferrocyanide. Ferric ammonium oxalate, potassium ferrocyanide and potassium ferricyanide are included in the coating solution and may be buffered by alkaline oxalates, citrates or tartrates. The fixing agents which may be applied in whole or in part immediately after drying the paper include zinc, nickel and cobalt salts of aliphatic or aromatic acids such as zinc salts of naphthalene sulphonic acid or phenol sulphonic acids, metallic salts of sulphuric acid esters of high fatty alcohols, zinc, nickel and cobalt sulphates, and even insoluble or slightly soluble compounds such as oxides, carbonates &c. These fixing agents may also be applied in the form of a fine dry powder. Oxidizing agents are added as intensifying or stabilizing agents and examples include bichromates, persulphates, stabilized compounds of hydrogen peroxide, chloramines, hypochlorites, and salts of paradichlorosulphonamino-benzoic acid. Oxidizing agents which combine the properties of fixing and intensifying include metallic peroxides, persulphates, chromates and double salts of alkali persulphates and hypochlorites. Buffer salts are included for stabilization after exposure to light and may be acid or neutral phosphates of the alkali metals or ammonia, organic salts of phthalic and benzoic acids, and calcium and magnesium salts. Stabilizing agents may be added to the coating mixture or during subsequent development, examples being chlorates, bromates and persulphates. Wetting-agents may be added to the coating solutions and its effect destroyed at any stage by a barium salt. Four examples of the preparation of prints having yellow, cream or white lines on a stable blue background are described in the Specification. Specifications 418,976 and 424,976 are referred to.

Abstract: 910,502. Air gunnery targets. BROOKLANDS AVIATION Ltd. Sept. 30, 1960 [Oct. 2, 1959], No. 33471/59. Class 4. A solid air gunnery target towing fins 5, 6, 8, has all or part of fin 8 movable during flight from a stowed to an operational position, whereby during take-off, the target can be carried below an aircraft with the fin 8 in the stowed position. Plywood fins 5, 6, 9 are fixed between angle members 2, 3, 4 and alloy fin 8 is pivoted at 10, 11 to fin 6 by torsion rod 12, the fins 5, 6 being braced by members 13. A parachute container 22 and a near miss transmitter 24 are secured to fins 5, 6 and a stop 15. A towing assembly 26, Figs. 1, 5, has an arm 27 pivoted to bracket 28 and connected to a parachute release cable 30 and a launching rope 33, a spring loaded stop 35 preventing premature pivoting of arm 27 and release of the parachute. The target is fixed to an aircraft by lugs 37 and members 38 are engaged with locating lugs on the aircraft. The rope 33 is connected by a releasable connector 39 and shackle 41, Figs. 7, 10 to a main towing wire 40, the shackle 41 being initially on an aircraft hook 42. Prior to launching, a catch 14 or fin 6, Fig. 4, releases fin 8 which is swung by torsion spring rod 12 to engage catches 18 on stop 15. The target is then released and falls away to the length of rope 33, the target then drags shackle 41 from hook and is then supported by ropes 33 and 40. At speeds above 148 knots, for example, the air pressure snaps stop 35 back over top dead centre to a release position. For release of the target, rope 40 is drawn in and connection 39 is released by engagement with a buffer 43; the rearward drag on rope 33 now pulls arm 27 clockwise, as in Fig. 5, due to the position of stop 35 and rope 30 withdraws pin 31 to stream the parachute. A radar corner reflector may be carried on container 22.

[Classes 35 and 38 (ii)] Machines with vapour or like rectifiers in place of commutators.- In a converting arrangement having a number of grid controlled valves control is effected by impressing on the grid of each valve a potential dependent on and derived from the instantaneous anode potential of the corresponding valve and means for periodically overriding this potential. As shown the arrangement comprises a frequency changer of the type in which windings 12, 13 of a synchronous motor 10 are connected to an A.C. circuit 11 through groups of valves 17-19, 20-22, 23-25 and 26-28, the current being successively commutated between the groups of valves so that a rotating field is produced by the currents flowing in the windings 12, 13, control being effected by applying to each valve a grid potential proportional to the anode cathode potential to maintain the valve non-conducting, an overriding potential being also applied periodically to render the valve conductive. Each grid circuit comprises a potentiometer 29 connected in parallel with the valve, the grid being energized from the secondary 32 of a transformer 30, the primary 31 of which is connected across a part of this potentiometer. The transformer 30 is provided with a third winding 35 which is periodically energized from a phase shifting transformer 36 through a distributer 37 driven by the motor 10 to cause the valve 17 to conduct. Rectifiers 52-63 are included in the supply to the windings 35 to prevent the occurrence of transients when the circuits are broken by the distributer. Specification 418,297 is referred to.

Title: Improvements in automatic vending machines
IPC: G07F11/18
Filed: 1935-12-04
Abstract: 449,228. Coin-freed article-delivery apparatus. WITTENBORG, E., 22, Seebladsgade, Odense, Island of Fyen, Denmark. Dec. 4, 1935, No. 33639. [Class 27] Relates to a coin-freed vending-machine having a number of drawers 1, Fig. 1, and a controlling rod 7, which can be moved longitudinally only after prepayment, to allow a drawer to be pulled out, this rod 7 extending along all the drawers, each of which is provided with a stopping rail 8 to enter between a pair 9, 10 of a series of movable blocking rods, so that the pulley out of one drawer locks all the others. According to the invention, a cam 5 for each drawer is pivoted at 3 on a fixed rail 4 and during the opening of the drawer is turned by a guide rail 2 attached to the drawer so that the cam presses on a pin 6 on the controlling-rod 7 and moves this rod, which movement is allowed by a known coin-freed releasing mechanism. When the drawer is fully pulled out to the position shown in Fig. 2, the rail 8 has entered between pins 11, 12 on the rods 9, 10 and moved these apart so that the corresponding pins on the other blocking rods have entered recesses 16, 17 on the ends of the other rails 8. Also the pins 6 on the rod 7 have moved over the end edges 14 of the rails 8 of the closed drawers further to ensure that they cannot be pulled out. When the open drawer is pushed in again, an incline 18 on the rail 8 engages the pin 6 and returns the rod 7 to its initial position, Fig. 1, the pin 6 returning the cam 5 to its initial position.
