Patent GB-471837-A (GB)
Title: Improvements in or relating to the manufacture of acetylene
IPC: C07C5/35
Filed: 1936-03-10
Abstract: Acetylene is made by heating to above 1000 DEG  C. under substantially atmospheric pressure, for a period less than one second, a mixture of a normally gaseous hydrocarbon other than methane with 3--9 times its volume of hydrogen; mixtures of normally gaseous hydrocarbons, including mixtures containing methane, may also be treated, and in this event the volume of hydrogen must be 3--9 times the volume of all the hydrocarbons in the mixture.  The products should be rapidly cooled, and this may be effected, at least in part, by heat exchange with fresh gas mixture.  Acetylene may be recovered from the products by means of a solvent such as acetone, and the residual hydrocarbons may be returned to the reaction or otherwise utilized.  The process may be effected in tubes of refractory material, such as silica or carborundum tubes, which may contain solid cores.  Various methods of heating the tubes are indicated.  In the examples: (1) a mixture of ethylene with four times its volume of hydrogen is passed through a silica tube heated to 1300 DEG  C. at such a rate that the reaction time is about 0,01 second; (2) a mixture containing methane 52, hydrogen 22, ethylene 18 and ethane 4 per cent is diluted with four times its volume of hydrogen and heated to 1460--1470 DEG  C. for about 0,01 second. Specification 440,432 is referred to.

Abstract: 971,524. Cams ; change-speed gears. FREDERICK PARKER Ltd. Sept. 4, 1963 [Sept. 5, 1962], No. 33959/62. Headings F2D and F2K. [Also in Division B1] In a timing unit for a batch mixing machine (see Division B1), a cam-shaft having groups of side-by-side cam formations, each group cooperating with a fixed trip device, is shiftable axially to select one of a range of rotational speeds, and to simultaneously automatically select a cam formation of appropriate length in each group for co-operation with the respective trip devices. As shown, the cam-shaft comprises a cylinder 3 freely rotatable on a spindle 4 which is rotatable and axially slidable in bearings in a casing 1 having a removable cover 1c. The main portion 3a of the cylinder 3 has groups 10-13 of cam slots and is rigidly joined to a sleeve 28, with a knurled collar 30, surrounding the spindle 4, while an end portion 3b has a group of slots 14 and is integral with a sleeve 27 and a knurled collar 29 surrounding the sleeve 28, a compression spring between the collars 29, 30 urging together intermeshing teeth on the portions 3a, 3b. The group of slots 14 can be angularly adjusted relative to the other groups by means of the collars 29, 30. Axial movement of the cylinder 3 and spindle 4 by means of a knob 31 on the end of the latter selects a required rotational speed, and hence cycle time, and at the same time brings the cam slot of the correct length in each group into line with its respective cam follower 15-19. The variable speed driving gear for the cam-shaft comprises an idler 37, carried on an arm 33b of a bell-crank 33 fast with the end of the spindle 4, which meshes with a pinion 32 on the end of the cam cylinder 3 and with one of a set of pinions 38 on a shaft 39 driven by a motor 25 through two worm and wheel reduction gears. To change gear, the spindle 4 is turned by the knob 31 thereon to move idler 37 away from the pinions 38 against the action of a spring 34 connected to the bell-crank arm 33d. The knob is then moved axially to bring the idler 37 and pinion 32 into line with the required pinion 38, and release, guidance and visual indication of the gear setting being provided by a pin 46 on the arm 33a engaging with a gate 48 (Fig. 5, not shown).
