Abstract: A catalyst for use in preparing vinyl cyanide from acetylene and hydrogen cyanide consists of an acidic aqueous solution of cuprous chloride containing in solution arsenic, antimony or bismuth, e.g. in the form of an oxide or salt, e.g. chloride. Materials which form soluble cuprous complexes, e.g. ammonium chloride, an alkali metal chloride or an amine hydrochloride are preferably incorporated in the catalyst.  In an example a catalyst is prepared by mixing in an atmosphere of nitrogen, cuprous chloride, ammonium chloride, bismuth tetroxide, powdered copper metal and water.  Concentrated hydrochloric acid is then added until the pH drops to 1.0 to 2.0 and the catalyst is then heated to 90 DEG  C.  Arsenic pentoxide may be used instead of bismuth tetroxide.  It is stated that arsenic trioxide or any of the oxides of bismuth may be used.ALSO:Vinyl cyanide is produced by passing acetylene and hydrogen cyanide into a catalyst consisting of an acidic aqueous solution of cuprous chloride containing in solution arsenic, antimony or bismuth.  These elements may be in the form of an oxide, e.g. arsenic pentoxide or trioxide or any of the oxides of bismuth may be used or they may be in the form of salts, e.g. the chlorides. Materials which form soluble cuprous complexes, e.g. ammonium chloride, an alkali metal chloride or an amine hydrochloride are preferably incorporated in the catalyst.  A molar ratio of acetylene to hydrogen cyanide of between 5 : 1 and 7 : 1 is preferred.  In examples: (1) a catalyst is prepared by mixing in an atmosphere of nitrogen, cuprous chloride, ammonium chloride, bismuth tetroxide, powdered copper metal and water, concentrated hydrochloric acid being then added until the pH drops to 1.0 to 2.0. The catalyst is heated to 90 DEG  C. and a gaseous mixture of hydrogen cyanide and acetylene passed in and the gaseous products condensed into a lower aqueous layer which is returned to the catalyst and an upper layer which is dried and distilled to yield vinyl cyanide; (2) as in (1), using arsenic pentoxide instead of bismuth tetroxide.

Title: Improvements in or relating to drum washing and centrifuging machines
IPC: D06F37/22
Filed: 1928-06-06
Abstract: 313,743. Aurich, M. June 6, 1928. Washing-machines with rotary receptacles.- The casing 1 in which the clothes receptacle, not shown, is rotated and which carries the motor 2 is supported by a framework 12 through intermediate, members 6, Figs. 1 and 3, or 23, Figs. 6 and 8. In the form shown in Figs. 1 and 3, channel-section bars 3 are secured to the casing and are formed with trunnions 4 which are received in rubber-lined eves 5 in the intermediate members 6 which also comprise channelsection bars. The lower ends of the intermediate members are ball-jointed at 8 to pins 9 which are formed with screw threads of opposite pitch, and, when operated by a connecting bail 14, work in nuts 11 secured to the framework 12. In the vertical or centrifuging position shown in Figs. 1 and 3, the casing is freely supported by the intermediate members which are prevented from rotating about their pivots 8 by engagement with the side cheeks of the inwardly-facing channel bars comprising the framework 12, additional lugs 16, Fig. 1, being provided if necessary. On swinging the bail handle 14, the pins 9 advance inwardly and the intermediate bars are caused to lie within the channel bars 3 secured to the casing ; they may then be rotated about their pivots 8 until the casing assumes the horizontal or washing position. In the form shown in Figs. 6 and 8 the casing is formed with depending lugs 28 having conical recesses in which are received conical lugs 29 projecting from bars 30 pivoted at 31 to the intermediate frame 23 which is itself pivoted to the main frame 12 at 22. The casing is also supported by being suspended from the highest point of the intermediate frame by a chain 27. Fig. 12, or other flexible connection such as a link which is ball jointed at both ends. The lower ends of the bars 30 pivoted to the intermediate frame are formed with rollers 32, Fig. 8, which engage the edge of a segmental member 33 projecting from the main frame to hold the conical lugs in complete engagement with the recesses in the lugs 28 when the intermediate frame has been rocked about its pivots 22 so that the casing is in the horizontal or washing position. The rocking of the intermediate frame to the vertical or centrifuging position shown causes the rollers 32 to enter cam grooves 34, Fig. 9, in the segmental members 33, thereby rocking the bars 30 and withdrawing the conical lugs 29 somewhat from the recesses in the lugs 28, so that in the centrifuging position the casing is supported in a non-rigid manner. In the horizontal position the end of the casing remote from the motor rests upon a cross-bar 35, Fig. 12, on the intermediate frame.

Title: Improvements in or relating to cartridges for recoilless fire-arms
IPC: F42B5/05
Filed: 1951-07-12
Abstract: 854,517. Ammunition cartridges. ABRAMSON, H. July 12, 1951 [Aug. 4, 1950], No. 16592/51. Class 9(1). A cartridge for the propulsive agent of openbreech recoilless guns is so formed that, on firing, it is expanded by the pressure of the discharge gases and is momentarily jammed fast in the chamber, but is adapted to contract upon the drop in gas pressure caused by the rupture of the cartridge and escape therefrom of gases both forwardly against the projectile and rearwardly against the case to eject the latter. In Fig. 1 the cartridge 4 is secured to the base 5 of the projectile 3 in the manner shown. On firing, the cartridge expands to become jammed in the barrel chamber 2 before the projectile is released from the cartridge. Subsequently the rear wall, which may be suitably weakened, by being made of reduced thickness or by having incisions, ruptures to enable the gases to pass to the rear, the projectile at approximately the same time having been discharged. The residual gases serve to expel to the rear the cartridge which has resumed its original shape and has become loose in the chamber. In Fig. 2 the cartridge is separate from the projectile and is provided with apertures 8 for the introduction of the charge and with slits 9 to prevent it from sticking in the chamber. To protect the chamber 2 the cartridge may be fitted with a sleeve 12, Fig. 4, which is expanded by the cartridge, on firing, into engagement with the chamber walls. The sleeve, or in other cases the cartridge itself, may be extended to the rear to serve as a handle when the projectile is introduced.
