Filed: 1942-04-20
Abstract: 550,614. Covering tennis &c. balls. BOWERS, A. C. April 20, 1942, No. 5205. [Class 132 (ii)] A tennis ball or like is covered by two fabric blanks of Cassinian outline applied simultaneously by mechanical means and shaped upon the surface of the ball with abutment of the two blanks at their edges as they come simultaneously into position. A press member for applying one cover blank to a tennis ball comprises two concave blocks 1, 2, Fig. 1, the concave faces of which swing towards one another so as to correspond in their closed position to the spherical surface of the ball, the concave faces then forming the Cassinian outline of one cover blank. The concave blocks are provided at their edges with discontinuous blank-retaining rims 13. Two press members are incorporated in the machine, one above the other, and in applying a cover a solutioned blank is placed in each press member and an uncovered ball is placed on the lower press member. The two press members are brought together and clasped around the ball as indicated in Fig. IV, to apply the cover blanks with their adjacent edges in contact except at the isolated positions where the discontinuous rims 13 make contact, these gaps however closing up during the subsequent vulcanizing process. Reference has been directed by the Comptroller to Specifications 551,602 and 554,949.

Filed: 1963-02-08
Abstract: 1,040,481. Oil-fired tunnel kilns; burners. A. STEIMER. Feb. 8, 1963 [May 7, 1962], No. 5312/63. Headings F4B and F4T. In a tunnel kiln for ceramics or brickware, having oil injectors 9 firing intermittently transversely to the direction of air flow, the injectors being arranged in groups of four, and each three groups being controlled so that the entire cross-section of the kiln is supplied with fuel, the last three groups of injectors 9 have mixing tubes 8 supplied with air in approximately stoichiometric proportions so that these injectors form a flame curtain reaching to the tunnel hearth or the floor of the kiln cars within which the combustion products from the upstream zones are completely burnt. The fuel and air supply to the burners are so arranged that the fuel concentration in the air varies continuously. The mixing tube may be a straight tube with a restricted outlet end, Fig. 4 (not shown), or it may have a wider part at the injector end with an enlargement 15 to create turbulence near the outlet, Fig. 5. In another embodiment, Fig. 6 (not shown), the oil is fed with a whirl to a chamber to which air is supplied tangentially, or axially. The chamber narrows to the burner pipe which is surrounded by a sleeve to recirculate some of the combustion products. Since the flame curtain reduces the rate of air flow through the tunnel, cooling air from the passages 3, Fig. 1, may be used in the kiln without over cooling.

Patent GB-639712-A (GB)
Title: Improvements in or relating to feed mechanism for automatic guns
IPC: F41A9/49
Filed: 1946-02-23
Abstract: 639,712. Automatic guns. HYDRAN PRODUCTS, Ltd., and MOTLEY, L. Feb. 23, 1946, No. 5705. [Classes 9 (i), 92 (i) and 92 (ii)] The breech device of an automatic gun constitutes a firing chamber adapted to enclose and support the successive rounds of ammunition at the moment of firing, the breech device being longitudinally split and adapted to open laterally to admit each round and then to close so as to enclose and support said round. In the construction shown, each projectile 4, Fig. 1 is mounted in a tube 3 which also contains the propellant charge and which is linked to other tubes to form a belt. In use this belt moves downwards to bring each tube and its projectile in line with the gun barrel 1, the tube being held between the two parts 5 of a split breech-block. When a round is fired pistons in each of a pair of cylinders 21 each move a corresponding rod 19 which, by racks 20, rotate threaded sleeves 17 which serve to open out the two parts of the breech-block. A piston in a third cylinder 27 causes a rod 28 to actuate rack-and-pinion mechanisms in casings 30 for advancing the belt to bring another tube into the firing position. Springs serve to return the pistons to their forward positions when the gas pressure falls, and the rods 19 may also serve to control the movements of lockiug lugs 22 which positively hold the parts 5 of the breech-block in the closed position. The forward end of each tube is bent over at 11 and this part 11 is deformed by the projectile on firing so that it projects slightly into the barrel and effects oburation. The tube must therefore be moved longitudinally away from the barrel to allow the belt to advance, and for this purpose the lugs on the tubes for the hinge pins are spaced to permit such movement, and a member 45, Fig. 3, positively moves the tube of a fired round away from the barrel 1. As shown, the member 45 is connected to a fork 42 which straddles the barrel, and the fork is connected to a sleeve 41 with which is associated springs 43 and 34, and a catch 40. When a round is fired gases enter a port 31 and act on a piston 33 which compresses the spring 34, the piston being then held in its rear position by a catch 35. The breech-block parts 5 are now opening and by reason of thin inclined ends move links 37, 38 to release the catch 40, thus enabling the spring 34 to overcome spring 43 and to drive sleeve 41, and thus the projectile tube, to the rear. The fork 42 at the end of its stroke moves a lever 46 linked to means for lifting the catch 35 ; the piston 33 can now move to its forward position, and when the next tube has been advanced to the firing position the various parts return to the position shown. The gases of explosion may pass to the rear through a nozzle 8, Fig. 1, in the case of a recoilless gun. Specification 639,766 is referred to. The Provisional Specification describes also a modification in which the tube 3 is closed by a shear plate which is blown away when a predetermined pressure is generated.
Patent GB-415732-A (GB)
Title: Improvements in aluminium coated metal and process of producing the same
IPC: C23C2/12
Filed: 1933-02-25
Abstract: 415,732. Coating with metals; cleaning metals; fluxes. FINK, C. G., 440, Riverside Drive, New York, U.S.A. Feb. 25, 1933, No. 5823. Convention date, Feb. 27, 1932. [Class 82 (ii).] Metals, particularly ferrous metals, to be coated with aluminium or aluminium alloys by dipping are pretreated so that the surface of the metal is highly charged or saturated with hydrogen. The pretreatment, in the case of ferrous metals or nickel, consists in heating the metal in hydrogen at a temperature of about 900‹ C. or above, the metal being thereby deoxidized and charged with hydrogen, the hydrogen being either occluded or present in the form of a hydride. In treating copper, a slightly lower 'temperature may be used. The metal is preferably treated with a solution of boric acid, borax, or other boron compound before the hydrogen treatment. In one method of carrying out the process a wire X, Fig. 1, is cleaned in one or more acid or alkaline baths 10, heated to red heat in an oven 12, passed through a bath 14 containing a concentrated solution of boric acid, passed through a furnace 16 containing hydrogen heated to 1000‹ C., and then passed through the aluminium bath 22 and finally wiped by wipers 45 to remove surplus aluminium. In an alternative form, Fig. 6, the oven 12 is omitted and the hydrogen furnace is not heated, the wire X being brought to the required temperature by the passage of an electric current, the contacts c, c<1> being placed before the boric acid bath and after the hydrogen furnace respectively. The wire is preferably introduced into the molten aluminium in such a manner that it does not pass through an oxide film. As shown in Fig. 3, the wire passes into the bath through an opening 20 below the surface of the molten metal, oxidation being prevented by hydrogen issuing from the furnace 16. The coated wire may be drawn out through a similar opening 26 or through the surface of the bath. In the form shown in Fig. 4, the aluminium pot is provided with a cover 30 having openings 32, 33 for the entrance and exit of the wire. Hydrogen is supplied by pipes 37 to maintain a reducing atmosphere in contact with the aluminium and a guide or roller 35 is provided to ensure the immersion of the wire. Aluminium-coated wire, rods, bars, beams, sheets, and strips, and shaped articles such as hollow-ware, nails, &c. may be produced by the process. The Specification as open to inspection under Sect. 91 describes also the pretreatment of the metal in gas mixtures containing hydrogen, e.g. mixtures of hydrogen with nitrogen, carbon monoxide, or carbon dioxide, such as blast furnace gas or blue gas. This subjectmatter does not appear in the Specification as accepted.
