Filed: 1942-06-27
Abstract: 558,955. Resinous polymerization products. ROBERTS, R. P., and JONES, K. June 27, 1942, No. 8862. [Class 2 (iii)] [Also in Groups VIII and XXIII] Cellulosic materials such as wood, paper, or fabric of cellulose or regenerated cellulose are bonded together by applying to the surfaces to be united a composition containing polyvinyl alcohol, an aldehyde, and a substance capable of catalyzing the acetalization of the alcohol by the aldehyde, bringing the surfaces together, and effecting the acetalization. The catalyst may be active only when heated, in which case the composition may be kept in the cold for some days before use, or may be active at ordinary temperatures. Heat-activable catalysts specified are hexamethylene tetramine, ammonium chloride or sulphate, compounds liberating sulphur dioxide when heated, e.g. sulphites and bisulphites of sodium and potassium, bisulphite compounds of aldehydes and ketones, and reaction products of sulphur dioxide with aldehydes and ketones. Catalysts active at ordinary temperatures are sulphur dioxide, hydrochloric, sulphuric, formic, or chloracetic acid, sodium or potassium bisulphate or acid phosphate, chlorides, sulphates, formates, acetates and chloracetates of iron, aluminium, zinc, tin, and titanium. The polyvinyl alcohol may be made by complete or incomplete saponification of polyvinyl formate, acetate, propionate, or butyrate. The aldehyde may be formaldehyde, acetaldehyde, benzaldehyde, butyraldehyde, acrolein, or furfural. The composition may be a solution in water and/or a lower aliphatic alcohol such as methanol or ethanol.

Title: Improvements in or relating to gun-barrels
IPC: C23C8/36
Filed: 1952-04-09
Abstract: A method of treating gun barrels comprises using the gun barrel as a cathode, and subjecting it to a glow discharge in an atmosphere of nitrogenous gas to form an iron nitrided surface, the discharge being conducted at a temperature of about 550 DEG  to 600 DEG C. and effected by periodical application of electrical energy at short intervals.  In the example described a gun barrel is suspended in a metal chamber filled with gaseous ammonia under a pressure of 0,7 mms. of mercury.  Instead of ammonia, a mixture of nitrogen, hydrogen and ammonia or ammonia and nitrogen or nitrogen diluted with a rare gas, may be used.  The gun barrel is connected to the negative terminal of a D.C. voltage source, e.g. a rectifier, and the metal chamber to the positive terminal, the voltage being such that the gun barrel attains a temperature of about 570 DEG C.  A steady voltage of 500 or 1000 volts is applied and at intervals of 3-5 secs.  Voltage impulses, about 10 times the steady voltage, with a duration of about 0,1 sec., are superposed for a period of 12-30 hours, e.g. about 24 hours.  In order to obtain equal treatment throughout the gun barrel a wire positioned axially of the gun barrel can be connected to the voltage source.  A hollow cathode effect can be produced by suitable choice of the gas pressure in relation to the distance of the wire from the inner surface of the gun barrel.  Several gun barrels may be positioned in parallel relationship for treatment in a cylindrical chamber.  Specification 427,623 is referred to.

Filed: 1916-06-29
Abstract: 125,401. Rudge - Whitworth, Ltd., Pugh, J. V., and Pountney, F. June 29, 1916. Projectile fuses.-Relates to percussion fuses of the kind comprising a metal tape which has a weighted end and is wound over centrifugal safety means normally preventing contact between a needle and percussion cap, a protective cover being screwed over the end of the fuse and removed before the projectile is placed in the gun. According to the invention, the inner end of the tape is so formed that it can only be applied to the mechanism when the tape is correctly positioned for winding in the right direction; and further, the weighted end is so formed that it does not prematurely leave the groove in which it is wound when the cover is removed. In the fuse shown in Fig. 1, the tape m is wound in a groove h so as to hold a bolt l in position between an inertia pellet c and a firing-needle f. The bolt has a flat face covering the percussion cap d, and a groove in which the needle engages is formed in the other face. A centrifugal bolt j engaging in known manner with an inertia detent k may also be provided. The tape, shown separately in Fig. 4, has its inner end n turned up at right-angles so as to engage in a slot, (not shown), formed in the fuse body and thus correctly position the tape. The weight at the other end is slit at q, so that it presses resiliently against the sides of the groove h. Fig. 3 shows another construction of fuse, having an inertia pellet c in combination with a direct-action striker-needle t. The tape m in this case holds in position a split collar u which is normally inserted under the head of the needle. A shearing-pin v is provided as an additional safety-device. The pellet c is held at " safe " by a centrifugal bolt l<2> and detent k, the bolt projecting through a tube c<1> attached to the pellet. Specification 125,400 is referred to.

Title: Loading tray for recoiling firearms
IPC: F41A9/16
Filed: 1960-03-16
Abstract: 868,949. Loading trays for recoiling firearms. BOFORS A. B. March 16, 1960 [April 8, 1959], No. 9275/60. Class 92. Relates to a loading tray for recoiling firearms wherein the loading tray is guided by parallel levers so that it can be moved between a position in which ramming of a round on the tray can take place and a position in which the recoiling parts can freely pass the tray. According to the invention the loading tray 3 is provided with a spring-actuated rammer 12 which is cocked during the first part of the movement of the tray 3 towards the ramming position and which is released during the last part of the movement, the loading tray being so supported that when it swings towards the ramming position, it obtains a movement in approximately the ramming direction. The loading tray 3 is supported by four parallel levers 4-7 from a plate 1 forming part of the elevating non-recoilirig parts of the firearm. In its raised position the tray permits the breech ring 2 to recoil and in its lowered position the tray permits the ramming of a round thereon. The rammer 12 is arranged on a rotatable shaft 13 between which and a housing 14, which is stationary in relation to the tray 3, are arranged two coil springs 15. The housing 14 is connected with the lever 5 via a link 16 so that when the tray 3 and thus the housing 14 move downwards, the lever 16 will turn the housing 14 in a counterclockwise direction whereby the coil springs 15 will be stressed. Immediately before the tray 3 reaches its bottom position a catch 17 is released whereby the rammer 12 will turn in a counterclockwise direction, being actuated by the stressed springs 15. A round on the tray 3 will thus be rammed as a consequence of the speed of the tray 3 in the ramming direction and also as a consequence of the action of the rammer 12. The up and down movements of the loading tray are activated by springs arranged in drums 21, 22 which contain shafts 23, 24 upon which the levers 5, 4 are arranged, the springs being stressed during the movement of the recoiling parts of the firearm.

Abstract: 794,293. Automatic gramophones. ANSAR, A. March 26, 1956 [April 1, 1955], No. 9335/56. Class 40 (2). In a record-changing gramophone in which records 1, 2 &c. are supported over a turntable 3 and on a guide pin 4 by supports retractible into the pin through slots 13 ... 15, the supports are in the form of arms 5 ... 7 pivotally mounted at a distance from the centre of the pin and at the periphery of a sleeve 8 axially movable within. the pin, so that each arm moves'in a plane tangential with the periphery of the sleeve which is not coincident with the plane of movement of any of the other arms. As shown, the sleeve 8 has a pin 10 engaging a slot 11 in the pin 4, and each arm is pivoted at 9 to the sleeve. The arms swing out by gravity when the sleeve 8 is raised, assisted, if required, by springs. Cam surfaces 12 on the arms engage the rims of the slots 13 ... 15. During the first part of the movement of the arms they may remain at the same height or be raised or lowered. The records above the lowest in the pile are held during the feed down by a cap 17 which is pulled down by a wire 18 and the end of which is expanded by a widened part of the pin 4 so as to grip the inside of the hole in the second lowest record. The upper edge of each slot 13 ... 15 may be modified as in Fig. 4 (not shown) so that when discs are lifted off the turntable the pin 4 is raised and in falling after removal of the discs forces the arms outwardly. The pin 4 may be retained in the raised position, the arms being held retracted so that a single disc can be placed on the turntable. When the arms are unloaded the weight of the sleeve 8, a rod 19 for pulling the sleeve down, and connected parts is utilized to stop the motor when the last record has been played.
