Abstract: 475,380. Mine-roof supports. WOOD, H. N., WOOD & CO., Ltd., H., and MOLL, W. Nov. 16, 1936, No. 31326. [Class 20 (ii)] Arched metal supports for roof mines of the type having concave shoes at their ends for abutment against segmental or curved resilient packing, have the ends of the support cut obliquely to the axis of the support whereby a relatively greater downward pressure than side pressure is transmitted than is the case in a support where the ends are cut normal to the axis. In one form as shown in Fig. 1, an I-section support 1 is provided with an oblique end and a concave metal shoe formed of angle bars 6, 6a pivoted to the end of the support and having downturned edges to bite into the support 3. The upwardly extending flanges of the shoe members may be cut away to receive the ends of the support. In another form, the shoe is formed of T-section metal with the web engaging between the webs of channel-section members arranged back to back to constitute the arched support. In still another form as shown in Fig. 7, the shoe 8 is formed of bent metal with upturned portions to engage the flanges of the support 1 or the ends of the support may be cut and bent to form an integral concave shoe; alternatively, separate angle portions, each with one flange curved, may be secured to the flanges of the support member.

Abstract: 1335137 Generator for ignition systems ROBERT BOSCH GmbH 6 July 1971 [7 July 1970] 31592/71 Heading H2A A generator system for use with a motor cycle internal combustion engine having electronic ignition comprises a set of magnets M<SP>1</SP> mounted inside a cylindrical, rotatable magnetic body 30 so that as they rotate they move past ends of (a) a first magnetic core 29 carrying an A.C. winding 15 for charging a storage capacitor 11, and (b) a second magnetic core 39 carrying a control winding 25 for triggering an ignitiion firing thyristor 20, the polepieces of two adjacent magnets M1<SP>1</SP>, M2<SP>1</SP> having extensions 42, 43 which project into their interpolar gap Z, and the thyristor triggering pulse being generated in the winding 25 as these two projections move past respective end faces 40, 41 of the second magnetic core. The end faces 40, 41 may themselves carry tapering magnetic projections (Fig. 2, not shown) so that the range of timing adjustment is increased. Alternatively (Fig. 3) they may carry magnetic members 45 which provide small auxiliary end faces 44 preceding the main end faces 40, 41, the size of the auxiliary end faces being such that they only cause a pulse of sufficient magnitude to fire the thyristor 20 to be generated when the rotor is rotating above a certain speed, so that when this speed is reached the ignition timing is suddenly advanced. The supply for the lighting &c. of the motor cycle may be taken from the winding 15 or from another winding on a further core.

Abstract: 218,925. Rude, J. Dec. 18, 1923. Coking processes; retorts.-In coking by the heat contained in the gases from a water-gas producer, an auxiliary heated gas, for example oil gas, is passed through the coking chamber during the " blow," the water gas during the " run " being used in the same manner. In a modified process an auxiliary gas heated by the gases from the " blow " or " run " is passed uninterruptedly through the retort. During the blow," gases from the producer c, Fig. 1, pass by a flue d through a heat exchanger e and escape by a pipe g, the auxiliary gas entering by a pipe r is heated in the heater e and passes by a flue h to the retort a. During the " run," the water gas passes through the heater e and valve f which is opened directly to the retort. A sieve o on the rotary retort a separates the fine particles, which fall into a pocket p, the larger pieces being supplied to the upper part b of the producer. In the apparatus shown in Fig. 2 during the " blow " the gases are burned in heaters b and w and escape by an outlet h. Oil supplied through a pipe g is vaporized in chamber f cracked in chamber e and the hot oil gas is passed through openings n into the retort m, the mixed gases passing out through outlet o. During the run the water gas passes through a pipe u and heater b, entering the retort through pipe l and openings n. The oil gas may be supplemented by introducing another gas through a pipe r.
