Title: Preparation of chromium sulphate
IPC: B01J41/04
Filed: 1973-04-12
Abstract: 1400674 Chromium sulphate from waste solutions PRODUITS CHIMIQUES UGINE KUHLMANN 12 April 1973 [14 April 1972] 17585/73 Heading C1A Chromium sulphate is prepared from waste solutions containing hexavalent Cr compounds by contacting them with either an ion-exchange resin or a water-immiscible solvent and the Cr is re-extracted using a solution of SO 2  and H 2 SO 4  which may be formed in situ. Hydrated Cr 2  (SO 4 ) 3  may be crystallized, or the solution may be alkalized to form the basic salt of Cr(OH)SO 4 . In the process using an ion-exchange resin the solution may first be adjusted to pH 0 to 6. The resin may be disposed in two columns. These columns A and B may be treated serially with H 2 SO 4  solution, then the solution to be treated may be passed in series through them. When A is saturated it is cut off and the solution passed directly to B, then A is treated with water and the washings mixed with the fresh solution passing into B. Column A may then be regenerated in closed circuit (including a cooler) H 2 SO 4  and SO 2  being fed in at one point and Cr 2 (SO 4 ) 3  removed at another. In the solvent process the solvent may be a long chain secondary or tertiary amine or a quaternary ammonium compound 0À1 to 0À5 moles/litre in an aromatic diluent, e.g. xylene, or it may be an alkyl phosphate, e.g. tri-butyl phosphate diluted with a hydrocarbon or preferably alone. The solvent containing Cr<SP>VI</SP> extracted from the original solution may be regenerated by treating with a solution of SO 2  in water H 2 SO 4  being formed in situ by oxidation of the SO 2 , the solvent may then be washed with water and this wash water treated with gaseous SO 2  to give the solution required to regenerate the solvent.

Title: Improvements in and relating to the melt spinning of polyalkenes
Inventor: BEAUMONT ALBERT GORDON
IPC: D01F6/04
Filed: 1958-06-04
Abstract: <PICT:0902141/IV(a)/1> Polyalkene filaments of round cross-section are made by passing hot, freshly-extruded polyalkene filaments, e.g. of polyethylene and polypropylene, into water having a surface temperature of at least 60 DEG C.  The water may be held at a surface temperature of 60 DEG -100 DEG C. by the heat given up by the filaments passing into the water.  Filaments may be passed downwards into a volume of water having a temperature of at least 60 DEG C. at the surface and successively lower temperatures as the depth increases.  Thus the hot filaments 1 may be fed into a tilted or upright open-ended tube 3 partly submerged in water 6 at ordinary temperature so that the filaments heat and maintain the water in the upper reaches of the tube to at least 60 DEG C., and emerge from the tube into water at the ordinary temperature.  The filaments are led around bars 7 and 8 and then leave the bath for further processing. Processes in which high density polyethylene is extruded at temperatures of 325 DEG C. and over, as in Specification 810,723, and processes in which filaments are simultaneously quenched and stretched, as in Specification 807,248, are disclaimed. Specification 472,051 also is referred to.

Title: Improvements in wireless communication and remote control systems
IPC: H04L1/08
Filed: 1928-06-22
Abstract: 292,916. Lorenz Akt.-Ges., C. June 25, 1927, [Convention date]. Atmospherics, eliminating; type-printing telegraphs.-In order to prevent incorrect recording due to atmospheric disturbances, particularly in high-speed wireless telegraphy using direct printing-devices, closed-circuit or back-stroke keying is employed and the undivided fiveelement Morse signals, corresponding to a definite letter or numeral are repeated on two or more sequences. The actuation of the selecting-devices at the receiving end is made dependent upon an additive effect, so that an incorrect record can only occur if the atmospheric disturbance is repeated in the same position and at the same strength in both sequences. Keying at the transmitter is effected under closed-circuit conditions so that the normal current and non-current sequences 1 - - 5 shown at Z1, Z2 in Fig. 2a are transferred as shown in Fig. 2b. Fig. 2c illustrates the double-sequence of each letter as actually transmitted. The setting-mechanism of the receiver only prints the signal after the second or repeated transmission, so that unless an atmospheric disturbance is repeated identically in both sequences the correct letter or numeral is selected. In transmission, keying is effected by means of rotating cam contact wheels which form the particular five-element Morse combination corresponding to the desired signal, whilst at the receiving station similar cam wheels, driven synchronously with those at the transmitter, effect a corresponding selection of five setting-devices and so ensure the direct printing or recording of the received signal.

Abstract: 277,936. Fox Gun Co., A. H., (Assignees of Henke, F.). Sept. 21, 1926, [Convention date]. Guns. - The trigger mechanism of a toy gun is enclosed in a frame formed of a plurality of pieces of sheet metal, and comprises a pivoted trigger passing through a slot in the frame and engaging a slot in the rear end of a firing pin that extends through a breech plate constituted by one of the frame members and is normally held in retracted position by a spring. The trigger is guided by the slots in the frame and firing pin, the forward end of the former slot acting as a stop against which the trigger is normally pressed by the spring. As shown, the triggers 5, 6 of a double-barrelled gun are mounted on a pin 26 extending through a frame 2 that is composed of three sheet metal members 9 - - 11, Fig. 9. The upper end of each trigger engages a slot 30 in the end of a firing pin 19 that is slidable within a vertically disposed part of the member 11 and is normally retracted by a spring 34. The lower end of each trigger passes through a slot 27 in the frame 2 and is normally pressed into engagement with the forward end of the slot by the spring 34. The rear end of the frame 2 is adapted to receive a wooden stock 1 and the forward end is pivoted to a number 3 carrying the barrels 4. The barrels are normally held in firing position by a staple 46 that projects from the barrels passes through a slot in the member 11 and is secured by a latch 48. The latch may be moved against the action of a spring 49, to release the barrels, by means of a lever 15 that is disposed above the frame 2 and is mounted on a vertical pin 51 from which the latch projects. A cartridge for use with the gun comprises a cylinder 61, Fig. 7, provided at one end with a flanged member 68 and at the other with an outwardly tapered tip 64 to receive and frictionally retain a light, wooden ball 65 that forms the missile. A plunger 87 is disposed within the cylinder and is normally held in such a position as to retain a spring 95 in tension, by means of a detent 77 projecting from a lever 75. Upon the actuation of a trigger, the corresponding firing pin moves forwardly to engage a bush 71, that is slidably mounted in the flanged member 68 of the cartridge and co-operates with an arm 79 on the lever, to release the plunger and thereby project the ball 65. The cartridge may be "reloaded" by pressing back the plunger into engagement with the detent 77, for which purpose the trigger guard 7 is provided with an extension 8 that acts as a ram-rod. Specification 278,321, [Class 9 (i), Ammunition &c.], is referred to.
