Title: Improvements in or relating to automatic lathe work-transfer mechanism
IPC: B23B7/12
Filed: 1961-03-21
Abstract: 915,282. Automatic lathes. BECHLER, A. March 21, 1961 [April 6, 1960], No. 10259/61. Class 83 (3). Automatic lathe work-transfer mechanism is arranged for feeding partly-finished workpieces 33, Fig. 1, from a channel member 26 to an automatic lathe chuck 3, Fig. 4. The lathe headstock 1 is provided with a pivoted transfer arm 8 which is moved by rack and lever mechanism 12a, 12, respectively, from a cam 11 on the main cam-shaft 10. An adjacent cam 16 moves the transfer arm axially along its pivot 5 through levers 17, 19. The channel member 26 is hand-loaded and the workpieces are spaced apart by fingers 28 on a bar 27 which may be oscillated by the transfer arm to disengage the workpieces. When the transfer arm is in position to pick up a new workpiece it is moved to the right, Fig. 1, so that a set-screw 32a pushes on the end of the channel member and slides it along against a spring 31. The workpiece is picked up in the end of the arm and the transfer arm rotates a small amount away from the lathe spindle (broken lines, Fig. 4) so that a lug 8d on the transfer arm engages a screw 30 on a part 29 of the bar 27 to rock it and free the workpieces from fingers 28. The transfer arm and channel member now move to the left, Fig. 1, bringing a new workpiece into position for the next transfer operation.

Title: Method for the production of hydrogen
IPC: C01B3/06
Filed: 1939-04-04
Abstract: 527,242. Hydrogen. KELLOGG CO., M. W. April 4, 1939, No. 10556. Convention date, April 18, 1938. [Class 90] Hydrogen is obtained by suspending a finely divided metal, e.g. iron, in a current of steam and causing the suspension to flow through an elongated confined zone, e.g. a tube, at reaction temperature. The oxide, e.g. Fe 3 O 4 , is then suspended in a current of reducing gas, such as a mixture of carbon monoxide and hydrogen obtained by partial oxidation of a hydrocarbon, and subjected to a reduction temperature, the metal so obtained being returned to the first stage of the process. In the apparatus shown, steam, superheated in a coil 4, carries finely powdered iron from a hopper 7 into a reaction pipe 10 and thence to a separator 12. Hydrogen and steam pass to a condenser 14 and hydrogen thence by the pipe 17 for disposal. The separated oxide is entrained by a current of heated gas obtained by the partial combustion of a hydrocarbon, e.g. methane, in a drum 36, and is carried through a pipe 27 wherein it is reduced to metallic iron which is returned to the hopper 7.

IPC: F42B39/02
Abstract: 106,614. Universal Patents Co., (Assignees of Batchelder, F. R.). May 23, 1916, [Convention date]. Pouches &c. - Woven pocketed carriers, such as are employed as cartridge. carriers, hospital corps belts, medical-officers belts, &c., are formed with a woven cover, which encloses the top, sides and front. As shown in Figs. 1 and 2, the woven belt 1 has one or more woven pockets 2, which are shown expanded by packages 3. Each cover is formed of two woven strips, one 4, 5, 6 passing from back to front and bent twice at right-angles, the other 7, 8 passing from side to side and also bent twice at right-angles. One extremity 4 of the first-mentioned strip is inserted in a housing- slit in the belt and is secured by stitching, and the two strips which cross at the top, making that part of double thickness, are stitched together along the four edges of the top. They are also stitched together along the side edges, the cover thus forming a hood for the pockets. The free ends of the front 6 and of the sides 7 are folded and hemmed. The cover is secured in place by a press-fastening 11, 12. Instead of the strip that passes from side to side being stitched to the top, it may be stitched to the front flap, thereby producing a hood having a single thickness at the top but a double thickness at the front. Or again, both top and front may be of single thickness. This may be done by stitching side flaps to the strip that passes from back to front, or by weaving a piece of the shape shown in Fig. 6 so that, when the edges 6b, 7<c> are secured together, it will form the desired hood cover. A number of such pieces may be woven in one length, as shown in Fig. 7, having alternately wide sections 70 and narrow sections 60, the intervening spaces being taken up by warp threads w floated between the widened portions. The long strip is then cut across as at x-x and the threads w cut away, whereby the pieces of the required shape are produced.. The widened portions may be woven in the flat state, as shown, or by a known method as shown in Fig. 8, with the wing portions w folded inwards, so as to take up less width in the loom. The invention is not limited to the forms of cover described, so long as the woven cover is of such a shape as to enclose completely the top, front, and sides of the pocket-like hood. Specification 16783/15 is referred to.

Title: Improvements in the manufacture and production of unsaturated hydrocarbons
IPC: C07C1/24
Filed: 1928-04-14
Abstract: 317,500. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 14, 1928. Hydrocarbons. - Unsaturated hydroaromatic and aliphatic hydrocarbons, particularly diolefines, are prepared by the catalytic dehydration of the corresponding hydroxylated hydrocarbons by passing them in the vapour phase over heated catalysts consisting of or containing such salts of the oxygen acids of phosphorus as have an acid reaction under the conditions of working, but not including tertiary sodium phosphate and aluminium phosphate. Suitable catalysts are such salts of the oxygen acids of phosphorus as when dissolved in water, react acid to litmus, and the neutral salts of the oxygen acids of phosphorus with those metals which stand lower in the electromotive series than sodium, e.g. the neutral alkaline earth phosphates such as calcium phosphate. Small amounts of free acids which are not volatile under the conditions of working, such as phosphoric acid, or substances such as ammonium phosphates, the phosphates of organic amines or acid esters which supply free acids under the conditions of working, may be incorporated with the catalysts. Ordinary, reduced or elevated pressure may be used, and the reaction may take place in two stages, the products from the first stage being eliminated before the second takes place. In examples, (1) butadiene is prepared by passing 1 : 3-butyleneglycol and water vapour over cerium phosphate, acid bismuth orthophosphate, acid cadmium orthophosphate, or neutral pyro- or ortho-phosphates of magnesium or the alkaline earth metals, or a mixture of calcium phosphate and ammonium phosphate, or primary sodium phosphate in admixture with graphite, or primary sodium phosphate containing phosphoric acid; (2) ethylene is prepared by passing ethyl alcohol over sodium metaphosphate and fuller's earth; (3) cyclchexene is prepared by passing cyclohexanol over sodium pyrophosphate; (4) isoprene is prepared from 2- methyl-1 3-butyleneglycol using sodium metaphosphate; (5) butadiene, is prepared from 1: 3- butyleneglycol using an evaporated solution of primary sodium phosphate and n-butylamine phosphate containing graphite.
