Title: Improvements in means for eliminating the flash, smoke, noise and recoil of guns andin ammunition therefor
IPC: F42B29/00
Filed: 1933-04-18
Abstract: 420,006. Guns and ammunition therefor. DUPRE, E., 51, Route de Choisy, Ivry-sur- Seine, France. April 18, 1933, No. 11343. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 16, 1933.] [Classes 9 (i), 92 (ii), and 119] Relates to means for reducing the flash, smoke, noise and recoil of guns of the kind in which an obturator 22, Fig. 2, for the gun gases follows the projectile and is arrested by an abutment 10 at the muzzle so that the gases can escape laterally through ports 5 in the barrel into a closed chamber. According to the invention, the projectile 25, Figs. 3 and 6, is guided in the barrel by a sheath 29 of stearin, paraffin wax or other readily destructible substance which is crushed between the abutment and the obturator the latter comprising a cup 22 of thin metal which is ejected laterally, as by means of a spring tongue 12, when the abutment is moved forwards by manual means after firing. The invention is shown applied to a drop-down sporting gun in which the abutment is given a forward sliding movement on the barrel by a rod 16 and suitable linkage when the gun is broken down. The gases then escape from the cylinder 4, through a flexible tube serving as a strap, or through tubular linkage, into a chamber in the stock. The form of cartridge shown in Fig. 3 comprises a part conical case 20, a chamber 23 for slow-burning powder, an obturator 22 enclosing quick burning powder 23<b>, a felt, cork or like wad 24 and a paraffin wax sheath for a shot-container formed of slit paper sleeves 27<a>, 27b united by a sleeve 28 of cigarette paper. In the modified cartridge shown in Fig. 6, the case is of cardboard and the obturator encloses a single powder charge 23. A sleeve 29 of stearin, with longitudinal grooves to reduce the bearing surface, completely encloses a shot-container formed of three paper sleeves placed end to end. The invention may be applied to a double-barrelled sporting gun having a cylinder 4 below each barrel and a single central rod 16 for sliding the abutment.

Abstract: 1505371 Making superconducting wire SOC ALLUMINIO E METALLI (ALUMETAL) SpA and COMITATO NAZIONALE ENERGIA NUCLEARE 19 March 1975 [22 March 1974] 11353/75 Heading B3A [Also in Division H1] A method of making a superconductor wire of Nb 3 Al comprises forming an assembly of alternate layers of Nb and Al, inserting the assembly into a Cu container, plastically deforming the container to reduce the thickness of the Al layers to less than about 1À5 Ám. and subjecting the result to heat treatment at a temperature between 800 and 1000 C. The assembly may comprise alternate sheets of Nb and Al with Nb on the outside, but in the preferred embodiment two sheets of Nb and Al are rolled up together on a Cu core, the Nb sheet being longer so that the inner and outer faces of the roll are Nb. The roll is inserted in a Cu sheath, and the result drawn, extruded, roll, or swaged down to the required size, e.g. rolled, then hammered, then drawn. The assembly may be heated during this deformation. The result is heat treated at 850 or 950 C. for half to two hours. To produce a multifilament superconductor, a plurality of sheathed assemblies are assembled in a further sheath. The plurality may be as assembled, or may be obtained by subdividing a single assembly which has been plastically worked to a reduced diameter. The wire may be subjected to tension before heat treatment to produce magnetic uncoupling of the filaments.

Filed: 1968-03-08
Abstract: 1,215,863. Glass-metal seals. IWAKI GLASS CO. Ltd. 8 March, 1968, No. 11474/68. Heading ClM. [Also in Division F2] A metal structure 1, such as a pipe, pipe fitting or valve body, is provided with a bore which is fixed with a glass tube 2 and which has annular recesses 8, 9 at the terminal ends of the bore receiving glass packing rings 4, 5 fused to the glass tube. As shown in Fig. 7, the glass-lined, flanged pipe of Fig. 1 is made by inserting a glass tube 3 sealed at both ends within the main pipe body 1, the glass sealing or packing rings 4 and 5 being retained with the glass tube within the main body by perforated end-caps 10 and 11. The assembly is then heated, preferably in a non-oxidizing atmosphere, to a temperature of about 20‹ C. higher than the glass softening temperature so that a predetermined quantity of gas, e.g. air, initially trapped in the sealed tube expands the glass tube into contact with the main pipe and the packing rings to form a unitary body. The end-caps are subsequently removed and the protruding ends of the glass tube cut away and the end face ground. A frit layer may be initially applied to the main pipe, particularly in the recesses. A substance, such as iodine or potassium chlorate may be used to generate a gas pressure within the glass tube on heating. In an alternate procedure, Fig. 8 (not shown), gas is fed to the glass tube through a pipe extending through one of the end caps. Other pipe fittings, namely a pipe bend, a taper junction piece or a valve housing, Figs. 2-4 (not shown), may be formed in the same manner. In Figs. 5 and 9-13 (not shown), a branched pipe fitting or tee-piece is formed in substantially the same manner as described except that the main bore and the branch bore of the fitting are lined in two distinct stages. In the first stage, a first glass tube is placed within the main bore and expanded into position, a stopper being positioned in the branch to restrict bulging of the portion of the expanded glass tube overlying the branch bore where it opens into the main bore, Figs. 10 and 11 (not shown). In the second stage, a second glass tube is placed in the branch bore and expanded into position, a tubular stopper being positioned in the main bore to prevent the second glass tube extending into the main bore. The end portion of the expanded second glass tube closing the bore of the branch is subsequently removed after removal of the tubular stopper, Figs. 12 and 13 (not shown). The glass forming the lining tube or tubes and the packing rings may have a coefficient of expansion in the range of 60 to 120 x 10-1/‹ C. and a composition of 8i0 2  71-0%, A1 2 0 3  3.7%, CaO 5-87%, MgO 0-2%, Na 2 O 17-5%, K 2 0 0-6%and B 2 O 3  1.2%.

Abstract: 693,730. Number-printing apparatus. REUMERMAN, T., and HELMIG, W. H. T. May 17, 1951 [Jan. 5, 1951], No. 11583/51. Addition to 693,554. Drawings to Specification. Class 100(ii) [Also in Group XIX] Number-printing apparatus according to the parent Specification, i.e. incorporating figure wheels for units, tens, hundreds &c. and an additional " checking " wheel carrying, and automatically set to display or print the appropriate one of, N distinctive symbols (N being a prime number greater than 10) corresponding to the various remainders obtained by dividing any number which may be shown by the figure wheels by N, is characterized in that the first figure wheel from the left (i.e. the thousands wheel in a four-figure machine) is an N-partite wheel adapted to be displaced over one N-th of its circumference after each complete revolution of the second figure wheel from the left. Thus as the apparatus steps from its maximum indication to zero the indicated check symbol remains in agreement with the correct check symbol. E.g. in a four-figure machine having an 11- position checking wheel, if the maximum reading were 9999 (for which the checking wheel symbol would correspond to a remainder of 0) the next step would move the checking wheel to display a symbol corresponding to a remainder of 1, which is incorrect for a reading of 0000; according to the invention the thousands wheel has eleven positions and carries figures from 0 to 10 so that the maximum reading is 10999 (remainder 10); the next step then moves the checking wheel to display a symbol corresponding to a remainder of 0, which is correct for a reading of 0000.
