Title: Improvements in or relating to metal coated articles and method of making the same
IPC: C23C2/02
Filed: 1938-03-25
Abstract: 512,963. Coating with metals. STEVENS, A. H. (National Standard Co.). March 25, 1938, No. 9194. [Class 82 (ii)l [ Also in Groups V and XXXVI] An article having a coating of a low melting- point metal or alloy, e.g., zinc, cadmium, tin, lead, or alloys thereof, is given a further coating of a metal or alloy which may be the same as or different from the initial coat, by first depositing on the initial coating by a cold method, e.g., electroplating, chemical deposition, or sputtering, a layer, preferably thin, of a metal which has a higher melting point than both the initial and final coating metals, and then applying the desired metal or alloy by hot dipping. The intermediate layer, which may be, for example, copper, antimony, nickel, cobalt, iron, chromium or silver prevents the molten coating metal from undesirably affecting the initial coat. The initial coat may be applied by dipping, electrolysis, or by a combination of these methods. For example, to obtain a thick zinc coating a thin layer of copper may be applied between two galvanizing operations ; a similar procedure may be used to obtain a thick tin coating on brass strips. A tyre bead reinforcing wire may be coated with zinc or cadmium, then with an intermediate layer of copper or nickel, and then hot dipped in zinc or cadmium. A layer of copper, antimony, or arsenic may then be applied to make the wire rubber adherent. Where antimony is electroplated on cadmium it may be deposited from a solution formed by dissolving sodium cyanide in warm water and adding antimony trisulphide to the solution, which is then heated to 120F. The antimony is preferably applied in such a thin layer that it is completely alloyed with the cadmium at atmospheric temperature or at the vulcanization temperature. Various other combinations of inner, intermediate, and outer coatings are specified.

Abstract: 1,001,628. Coaxial pipes; pipe couplings. SPEMBLY Ltd. Feb. 28, 1964 [March 8, 1963], No. 9195/63. Headings F2G and F2P. Each of a plurality of pipe sections forming a pipe-line for conveying liquid helium comprises inner, intermediate and outer spaced concentric tubes, 1, 6 and 2 respectively, and a tube 7 conveying liquid nitrogen in contact with and extending longitudinally along the intermediate pipe exterior surface, the intermediate tube forming a radiation screen in the individually evacuated space of each pipe section between the inner and outer tubes. In the embodiment shown, the outer tube is welded to end flanges 3 centrally apertured to receive flanges 8, 9 of the intermediate copper tube. These latter flanges are connected to the former by two pairs of concentric thin-walled stainless steel tubes 10, the tubes of a pair being interconnected at one end and secured to the flanges 3 and either 8 or 9 at the other. The inner liquid helium conveying tube 1 and the nitrogen conveying tube 7, soldered to the intermediate tube, are displaced longitudinally relative to the outer tube and are each provided with ferrules 11 and 12, respectively supported by thin-walled stainless steel tubes 13, 14 and 15, 16 connected to flanges 3 and flanges 8, 9 respectively. Leakage is prevented by a good fit between mating ferrules of adjacent pipe sections and by recessed O-ring gas seals 4, 5 in the flanges 3. Thermal expansion is accommodated by a bellows section 17 in the tube 1, by forming the tube 6 in two portions in telescopic engagement, and by providing the soldered tube 7 with a free helically-wound form about the said engagement. The relative spacing of the tubes may be maitained by triangular plates 19. In a modification, Figs. 3, 4 and 5 (not shown), the nitrogen conveying tube is brought out through a threaded boss provided in the outer tube wall, the end of the nitrogen conveying tube being fitted with a ferrule which is connected to the said boss by a thin-walled stainless steel tube. The ferrules of adjacent pipe sections are interconnected by a vacuum-jacketed U-member incorporating an expansion bellows. In both the above constructions, the interior of the outer pipe is maintained at a vacuum below 10<SP>-3</SP> mm. of Hg and the various pipe surfaces may be polished to reduce radiation bosses. Fig. 6 (not shown) illustrates a liquid nitrogen supply system to a pipe-line constructed of pipe sections in accordance with the modified embodiment.

Abstract: 1,174,802. Selective printers &c. MOHAWK DATA SCIENCES CORP. 27 Feb., 1967 [15 March, 1966], No. 9273/67. Heading B6F. An electrostatic or electromagnetic printer having an endless band 12 on which latent character images are formed by a matrix head 16 in response to application of coded signals, representative of a selected character, to wires 14, is adapted for continuous latent character image formation and intermittent line-by-line printing in that a portion of the band is advanced continuously by feed rollers 20, 22 past the matrix head 16 whilst another portion of the band is held stationary opposite a platen 28 and a pusher 32, through the intermediary of two suction columns 46, 47 which are controlled by valves 48, 50 to form intermediate stores in which the band is stored in depending loops prior to and after the formation of latent character images. In operation the portion of the band 12 on which the latent character images c are formed is withdrawn from the column 46 whilst the valve 48 is shut and stored in the column 47 whose valve 50 is open, the storing of the band occurring during the period when the other portion of the band is stationary for transfer of the latent character images c on to a record medium. The other portion of the band is arrested when a scanning head 34 senses a synchronous signal s, used to stop drive rollers 40, 42, which when re-started advance the band 12 into the suction column 46 at a speed which is faster than that of the feed rollers 20, 22. Scanning head 34 is associated with a control 36 which is also responsive to the signal s to actuate the pusher 32 and valves 48, 50.

Title: Vehicle door fastenings
Inventor: CHANARYN VICTOR
IPC: E05B65/32
Filed: 1953-04-07
Abstract: 744,681. Latches. WILMOT-BREEDEN, Ltd. March 26, 1954 [April 7, 1953], No. 9349/53. Class 44. Relates to a vehicle door fastening of the kind comprising a spring-loaded rotatable claw c to engage a peg on the complementary part of the fastening, a ratchet d secured to the claw c, a pawl g to hold the ratchet d against clockwise rotation, a pivotal release member operable from either side of the door for disengaging the pawl g from the ratchet d and a movable stop r operable from the inside of the door for preventing disengagement of the pawl g from the ratchet d by actuation of the release member from the outside of the door. According to the invention the release member is formed by a pair of pivotally interconnected and spring- loaded parts i and h, of which h is operable from the outside of the door while i is operable from the inside, the part i being adapted for engagement by the movable stop r and also being adapted to impart a release movement to the pawl g, the construction being such that when the stop r engages the part i operation of the part h from outside the door does not cause part i to release the pawl g. The parts h and i are pivoted to each other at o, the part i extending beyond the pivot o to form an arm q at one end and engaging a stump p on the pawl g at the other end. The ratchet d and the pawl g are pivotally mounted between plates a and b with the claw c rotating with the ratchet d on the far side of plate a. Part h of the release member is pivoted freely on the same pivot k as the pawl g, and is connected by a spring j to the part i so that when the flange m on the part h is pressed to the left by a push-button from outside the door the spring j draws the part i against the stump p on the pawl g to release the fastening against the restraint of a spring n. Similarly, if the arm q of part i is pushed downwards, by means associated with the inside of the vehicle, the pawl g is deflected. Actuation of the fastening from either side of the door is prevented by a stop r which can be moved to a position under the arm q where it directly blocks operation by means of the arm q and, by acting as a pivot for the part i as a whole, causes the lower end of part i to move away from the stump p when pressure is applied to the flange m on the part h by the push-button from outside the door.

In a machine vending a number of different types of article, released articles fall down a collecting shoot 3 and through an aperture 18 in a separating member 6 into a receptacle 5 which is pivoted at 8 so that it can be tilted outwards by a handle 9 to give access to released articles and to move the bottom upwards to constitute a shield between the delivery opening 17 and the stored articles. The separating member prevents access to the stored articles through the half-opened receptacle and any articles dislodged, for example, by means of a wire, fall down into the machine itself. The receptacle may be positively locked in the closed position by a solenoid 10 which, is energized to free the receptacle by the operation of the coin mechanism. To ensure that the receptacle returns to the closed position, a counterweighted lever 13 is pivoted on the pivot 8 and is engaged by a lug 14 on the receptacle; on the return movement, the lever is caught in a sling 15 so that the receptacle finishes the last part of its movement under its own weight. The lug 14 may operate a contact 16 in the article-vending circuit to prevent release of articles if the receptacle is not in the fully-closed position. The solenoid 10 and contact 16 may be replaced by mechanically-operating means. The articles may be stored in vertical or inclined shoots or, as shown, may be released from tiers of storage belts 1, the selected articles operating trip contacts 4 to disengage clutches driving the selected belts.
