Title: Improvements in and relating to variable speed power transmission mechanism
IPC: F16H61/02
Filed: 1925-04-21
Abstract: 235,509. Hayes, F. A. April 21, 1925. Facilitating changing speed.-To reduce shock on changing mesh of gear and clutch teeth, locking-means operates automatically to prevent shifting into mesh until the teeth are moving at nearly equal speeds. The locking-device 35b, Fig. 3, which prevents selector bars 30, 35 from completing the shift, is controlled by automatic means for synchronizing the gear wheels &c. comprising auxiliary friction gearing 41, 44, 43, Fig. 1. A gear 31 is slid upon the driven shaft 10 to the right into clutch engagement with a pinion 20 on the driving-shaft 14 for solid driving, and to the left into engagement with a gear 23 on a lay shaft 22 for intermediate speed. A wheel 28 is slid to the right into engagement with a layshaft gear 24 for low speed, and into engagement, for reversing, with an idle gear 26. The gearing is operated from a lever 36, Fig. 2, through selector bars 30, 35, Figs. 3 and 5, which have each a cam connection with locking bolts 30<a>, 35a, which have to be depressed before a change of speed can be completed. Such depression is prevented by the T-shaped bolt 35<b> engaged by a stop 51, Fig. 5, on the intermediate friction pinion 44. In changing speed, the main clutch is disengaged, which brings a clutch brake 18<c>, Fig. 1 into action to retard the shaft 14. A rod 55 is next actuated which advances the friction disc 43 against the pinion 44. The shaft 10 still rotates with the result that the pinion 44 moves so as to withdraw the stop 51 and allow the change to be completed. The pinion 44 is slidably mounted on its shaft so that it can rise and fall with respect to a line of centres 10, 29, Fig. 3<a>. The effect of this obliquity is that the pinion moves round in a closed path the position of which is different for different speeds. In case the friction gearing should fail, the locking stops 30<a> &c. may be replaced resilient ones which can be passed by main force.

Title: Improvements relating to the treatment of hydrocarbon gases
IPC: C07C11/02
Filed: 1931-04-09
Abstract: <PICT:0385981/IV/1> The thermal treatment of gases which contain paraffins and may contain olefines is carried out in two or more stages, combined as follows: (a) olefines are produced at 650 DEG -800 DEG C., and then polymerized and condensed at 350 DEG -550 DEG C., preferably under pressure; or (b) the gas obtained from the first stage of (a) is treated at 700 DEG -850 DEG  C. under conditions in which aromatic substances are formed, and the residual gas may then be treated at 350 DEG -550 DEG  C. to polymerize olefines; or (c) the first stage is carried out at 800 DEG -1050 DEG  C., under conditions in which olefines and aromatics are produced, the olefines are then polymerized or condensed, and the residual gas may then be treated at 650 DEG -800 DEG  C. for the production of olefines, or (d) the olefines of the initial gas are removed by polymerization, and the residual gas is treated as in (a) above.  The treatment may be carried out in apparatus made of or lined with glass or silica or a suitable metal such as copper, aluminium, stainless steel, or heat-resisting steel, of which suitable compositions are given. The olefines may be purified before treatment, and condensates may be removed between the stages.  The pressures used in the condensation stage may be between 200 and 2000 lbs. per sq. in. and with increase in pressure the working temperatures should be slightly reduced.  In the polymerization and condensation of olefines when admixed with relatively inert gases such as hydrogen, the partial pressure of the olefines approaches the usual total pressure of olefines when the reaction is carried out in the absence of inert gases.  As the partial pressure of the olefines diminishes during the polymerization, the conditions of treatment may become more drastic, e.g. the temperature may be increased, or this reaction may be conducted in several stages with interstage cooling to remove liquid polymers.  The polymerization may be conducted in the apparatus illustrated, in which the olefine is passed through a compressor b, catchpot c, preheater d, reaction chamber e, cooler f and high-pressure catchpot g, from which the gases may be recirculated. The whole process may be conducted in apparatus such as that described in Specification 309,455, [Class 2 (iii), Dyes &c.].ALSO:In the thermal treatment of hydrocarbons, the apparatus used may be made of or lined with alloys containing specified proportions of iron, carbon, silicon, and manganese, with chromium, copper, and molybdenum, or chromium and nickel, or copper and molybdenum.
