Abstract: 347,121. Rotary retorts for distilling oil shale. DAVIDSON, T. M., Homeleigh, Hatch End, Middlesex. Oct. 17, 1929, No. 31579. [Class 55 (i).] In a rotary retort for the distillation of oil shale or the like, for removing deposit from the retort wall, scrapers or cutters are provided which make an obtuse angle with the retort surface and are reciprocated along the length of the retort, and the gas outlet comprises a fixed tube extending through the retort eccentrically of the axis and supporting the scrapers. Gastight joints at each end of the retort are formed by a number of split rings in a seating on one surface, and making sliding contact with the other surface. The residue is charged direct to a furnace for heating the retort. A cylindrical retort a is mounted in a heating chamber b<1>, communicating with a furnace b<2>, and is carried on rollers a<2> and rotated by gearing a5. The retort is charged by a feed-worm c<3> capable of axial movement, and a gastight fit is provided at the feed end by split rings c<4> fitting a cylindrical flange a<8>, and pressed by screw-threaded plugs c<8> and springs c<7> against a shoulder of the charging tube c<2>. A similar arrangement at the discharge end is provided by split rings e<1> contacting with a T-shaped ring d<2> on the stationary discharge chamber, and with a flange e<2> on an extension of the retort. The residue passes through a conduit f to the furnace. A gas outlet tube h of semi-circular cross section is mounted on a flange h<1> at the dipscharge end, communicates with an external outlet d<3>, and extends into the retort as far as a bearing i. A tubular casing extends from bearing i to bearing k. The flat portion of the outlet tube is extended at h<4>, Fig. 5, to support sliding plates l to which are attached scrapers m<1>, the plates l being secured to a plate n mounted on a reciprocating rod o which also carries scrapers moving over the lower surface of the vapour outlet tube hand casing j. The rod o is attached by a block 0<2> to an operating rod q extending through the feed worm to supports q<3> which are reciprocated by worm gearing r. The hollow shaft of the feed mechanism may serve as a water-vapour outlet tube from the fresh charge. Specification 347,142 is referred to.

Abstract: 721,865. Spring suspensions; preventing lateral canting. DAIMLER-BENZ AKT.-GES. Dec. 15, 1952 [Dec. 15, 1951], No. 31801/52. Class 108 (2). In a vehicle suspension for rear wheels mounted on oscillatory axle members such as pivoted half-axles and wherein an axle member operates its respective suspension spring through the medium of a lever arm, the lever arm is short relatively to its associated axle member and has one end mounted on a pivot disposed on the vehicle frame outwardly of the pivot of the axle member whilst the other end is caused to bear directly upon the axle member by the suspension spring connected with the lever arm, the arrangement being such that when the axle member is deflected due to a rising of its respective rear wheel from a normal or middle position the point of bearing contact of the lever arm upon the axle member, moves along the latter whereby a change in the effective leverage takes place and brings about effective spring hardening. In the arrangement according to Fig. 1 a swinging half axle 13 for a rear wheel 12 is sprung by rubber torsion springs 14 connected in series such. that the foremost spring 14 is clamped to the vehicle chassis while the rearmost spring is connected by a shaft 17 with a lever arm 18 which engages the half axle 13 through a rubber roller 19. In its middle position the arm 18 is inclined inwardly of the vehicle and upwardly from a pivot point 16. In the arrangement according to Fig. 2 a torsion rod spring 20 mounted in bearings 21, 22 and 23 is cranked to form an arm 24 which engages a half axle 13 through a rubber roller 25. The spring 20 is combined with the corresponding spring on the opposite side of the vehicle, the springs being interconnected by a length 26.

Filed: 1952-12-22
Abstract: 703,610. Control of D.C. motors. GENERAL MOTORS CORPORATION. Dec. 22, 1952 [Jan. 2, 1952], No. 32368/52. Class 38(3) [Also in Group XXXVIII] An engine E drives a compound wound generator G for supplying traction motors having series field windings F1-F4 and armatures A1-A4 respectively, the motors being adapted for series-parallel control. To institute rheostatic braking, the motor field windings are connected in series across the generator and the armatures of the motors are shunted across individual resistors BG1-BG4. At the same time, a shunt field winding SF of the generator is disconnected from its armature and is placed across resistor BG2 with reversed. polarity so that it now opposes a battery-supplied field winding BF of the generator G. Thus, when the vehicle is braked at high speeds, the motor armature currents are limited by decreasing the generator excitation together with that of the motors. This results in a braking characteristic which allows a close approach to the maximum braking effort throughout a wide speed range of the vehicle. The generator field winding BF is connected to a battery BAT in parallel with an auxiliary generator 26 and has a regulator rheostat 28 controlled by governor 31. A potentiometer arm 48 is set to a position corresponding to the desired degree of excitation of the winding BF, and, when the potential at point 41 exceeds that of the arm 48 by a predetermined amount, current passes through relay winding 37 and rectifier 43 so that a relay 36 closes contacts to energize an overriding solenoid 31a. This solenoid then acts through the governor to increase the effective resistance of the rheostat 28 and thereby reduces the potential at point 41 until the relay 36 is deenergized, reverse current flow through the relay being prevented by the rectifier. The shaft 32, which is spring-biased, then moves to decrease the resistance of the rheostat 28 and causes a recurrence of the above sequence. A substantially constant current is therefore supplied to the field winding BF for any given setting of the arm 48. The system may be included in each unit of a train of vehicles, couplers 50 connecting the train line conduits TLC of the various units. The setting of the potentiometer 45 may be made in only the leading unit, and in any subsidiary unit the potentiometer may be disconnected by opening a switch corresponding to switch 51.

Abstract: The deterioration of rubber with age is retarded by the addition to the mix of an ether of a homologue of hydroquinone. The compounds may be expressed by the general formula <FORM:0476712/V/1> where R is a monovalent aliphatic hydrocarbon group, such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, secondary butyl, tertiary butyl, amyl, hexyl, decyl, hexadecyl; or other alkyl group either straight or branched chain; allyl, crotyl, and other unsaturated groups, or a cyclic hydrocarbon group, either cycloaliphatic or aralkyl, such as cyclopentyl, cyclohexyl, methyl-cyclohexyl, cyclohexenyl, benzyl, methyl-benzyl, cuminyl, mesityl, phenethyl, hydrocinnamyl and menaphthyl groups, which, although not strictly aliphatic in nature undergo the characteristic reactions of and confer upon their compounds essentially the same properties as purely aliphatic groups. In an example the behaviour of the monobenzyl ether of hydroquinone in a rubber mix is described.  It is stated that the anti-oxidants of the present invention are particularly useful in white and light coloured rubber mixes, and have a strong action to retard flex cracking.
