Abstract: 392,050. Railway barriers. BYRNE, E. L. W., 329, High Holborn, London.- (Grade Crossing Guard Corporation ; 834, Union Avenue, Memphis, Tennessee, U.S.A.) Sept. 19, 1932, No. 26011. [Class 104 (ii).] A barrier for crossing roads or a railway lever crossing comprises bumper members 17 located in line across the road and housed below the road surface in a channel-iron frame and adapted to be raised above the road surface through a resilient transmission at a varying rate determined by an oil dashpot device. The bumpers are pivotally mounted on resilient hinge members 20 which yield to allow the bumpers to engage abutment bars 15 and brackets 22 on the frame when a load passes. To raise the bumpers an electric motor 23, Fig. 3, is energized, as by an approaching train at a sufficiently distant contact, to drive through worm gearing 28 a shaft 29 provided with a crank 30 and linkage 33 whereby a shaft 34 is moved to stress a torsion spring 41 which acting on the hub 46 with crank 45 raises the bumper through the linkage 56. The weight of the bumper is balanced by a torsion spring 54 also acting on the hub 46. The bumper rises quickly, exposing warning lamps, until the lost-motion in. the connection 68 to the dash-pot 66 is taken up ; thereafter the bumper rises slowly until the descending dashpot piston, Fig. 11, uncovers a second throttle 86 whereupon the bumper accelerates to its full position. Load due to impact of a vehicle would be taken up by the lug 21x engaging the top flange of the frame member 14. The stress on the balancing spring 54 can be adjusted and retained by a pawl and ratchet device 51.

Title: Current limiting device for rectifiers
IPC: H03D1/16
Filed: 1930-09-01
Abstract: 362,364. Rectifying alternating currents. DAVIS, H. G., 56, Wickham Avenue, and CLARK, H. V., Merlin, Wickham Avenue, Shirley, Croydon. Sept. 1, 1930, No. 26100. [Class 38 (ii).] In a valve rectifer a voltage dependent on the input voltage is, applied to a grid of the rectifier in such a manner as to oppose a positive bias also applied to the grid while the rectified current is flowing through the valve and thereby to limit the current. A triode valve 1 is fed from an A.C. supply through a transformer 2 the secondary of which is connected in series with a resistance 4 in the anode circuit of the rectifier. A resistance 10 having a tapping 8 connected to the grid 11 is connected in series with a grid-biasing battery 9 across the primary 7 of transformer 2. The transformer connections are so arranged that the voltages applied to the grid and anode oppose. When the applied voltage rises above a certain value the negative value of voltage applied to the grid causes the valve to become non conductive and thus restricts the output of rectified current. In a modification a condenser is put in series with the resistance 80. In another modification the transformer 2 has a second tapped secondary winding which is connected in series with a biasing battery to the grid. In a further modification, the grid circuit is supplied from a separate transformer the primary of which is connected in series with a resistance and a condenser across the A.C. supply.

Filed: 1927-10-06
Abstract: 278,727. Maschinenfabrik Rheinland Akt.-Ges. Oct. 11, 1926, [Conven tion date]. Rollers, treating; balls, shaping and surfacing.-In a machine for grinding rollers, these are passed through grinding passages formed between a stationary grinding-block and a grinding block reciprocated in the direction of travel of the rollers &c., and are passed in succession through two or more passages, either from the same end thereof or from opposite ends. In Figs. 1 and 3, the block 1 is reciprocated and the block 3 is stationary, parallel grinding-passages 4, 5 being formed therein, and the rollers 6 are carried through the passages in opposite directions by a cage band 7 having recesses 8 for the rollers and carried by wheels 11, 12; surfaces 14, 15, on which the rollers rest when outside the passages, are reciprocated to turn the rollers partially prior to their entry into a passage; the band may be arranged to carry the rollers through more than two parallel passages. In the machine shown in Figs. 4 and 9, the guiding-block 1 is reciprocated by a lever 27, and the rollers 6 are pushed through the channels by oppositely moving rams 20, 21 acting on alternate channels and reciprocated by levers 24, 25. The rollers are carried up to, and removed from, the channels by intermittently moved conveyer bands 28, 29 the timing being such that a roller ejected from a channel by the ram 20 is moved opposite the next channel and pushed thereinto by the ram 21; tables 34, 35 cause the rollers to rotate partially during movement from one channel to the next. The conveyer bands may be replaced by recessed discs, or by oscillating-levers with end notches to receive the rollers. In a further modification, the rams move in the same direction and the rollers are moved from one passage to the next by reciprocating pushers or endless chains, rollers moved thereby into a position away from a channel being transported to a position whence they are again moved by the pusher to a position opposite a channel. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the machine to the grinding of balls; also the upper block 3 may be lifted to allow free entry of the rollers into the channels, being then lowered for grinding. This subject-matter does not appear in the Specification as accepted.
