Title: Device for electric rail brakes
IPC: B61H7/02
Filed: 1952-04-28
Abstract: 710,809. Track-brakes. AKTIEBOLAGET EKSJOVERKEN. April 28, 1952 [April 27, 1951], No. 10657/52. Class 103(1) In rail brakes for rail vehicles, each rail brake is carried by at least one elastic resilient element of rubber or the like material which allows displacement of the rail brake in the vertical direction as well as turning the same about a longitudinal axis and furthermore absorbs the braking forces in such a manner that the resilient elements undergo a deformation when the brake is applied and assume their original shape when the brake is released, simultaneously restoring the rail brake to its initial inoperative position. Fig. 1 shows the rail brake 1 in its inoperative position and suspended by two rubber elements 2, vulcanized to end plates 10 which are respectively secured to bracket 13 attached to the rail brake and bracket 12 attached to the bracket 6 on the bogie or chassis of the rail vehicle 3. Should the braking stresses on the rubber elements 2 become too great, a safety device is incorporated 14, 15, 18 to prevent the rail brake 1 from falling down on the rail 7 if the rubber breaks, the bracket 18 also serves to prevent excessive lateral movement. When the brake is applied (and the current is switched on) the brake 1 is brought into flexible contact with the rail 7 and when the current is switched off the rubber elements 2 return the brake to its initial neutral position. In a modification, Fig. 5, the rubber element is formed as a vertically working compression spring 19 having one portion 20 secured to the rail brake 1 and the inner portion 21 secured to a pin 22 projecting downwards from the bogie or chassis. A safety device is incorporated should the rubber shear so that the inner portion may rest on the washer 24 thus preventing the rail brake from falling. The brake may be held lifted by air pressure, electric magnet or the like.

Abstract: 780,619. Wet cleaning of asbestos fibres. RAYBESTOS-MANHATTAN, Inc. April 15, 1955, No. 10982/55. Class 82(2) Milled asbestos fibres are cleaned by a froth flotation process in which the fibres and flotation reagents are premixed and introduced into a flotation cell in which the fibres are subjected to turbulence and forced downwardly below the surface of the aqueous fluid in the cell whilst at the same time being propelled forwardly, so that the fibres form a turbulent advancing cloud below the surface level but leaving a relatively quiescent zone beneath the cloud into which the impurities settle by gravity, and then permitting the fibres to rise to the surface at the far end of the cell to be collected. Suitable reagents are dioctyl sodium sulphosuccinate, keryl benzene sulphonate, hexadecyl benzene sulphonate alkyl aryl sulphonate, sodium oleate and ammonium oleate. An apparatus disclosed comprises a premixing tank 10 with agitating means to ensure a homogenous pulp, with a pump 22, pipes 20 and 21, which can if desired be used to aerate the pulp by circulating it through the jet 23, and a flotation tank 16 with paddles 24 for depressing and propelling the pulp whilst impurities settle. Deflecting means 25 are also provided to assist the depression. At the far end of the tank the fibres are allowed to rise and are recovered by a paddle wheel 27. In modifications a series of spitzkasten are formed at the bottom of the tank for evacuation of the impurities, inclined propellers are used for depressing and propelling the pulp, or a series of water jets perform the same service.

Title: Improvements in apparatus for operating the barriers of railway crossings
IPC: B61L29/22
Filed: 1922-04-20
Abstract: 178,850. Hasler Akt.-Ges. vorm. Telegraphen-Werkstatte von G. Hasler. April 20, 1921, [Convention date]. Operating and controlling barriers electrically and magnetically, by treadles and the like, and by springs, weights, and toothed-gear mechanism. -The barrier of a railway crossing is moved into the down and up position alternately under the influence of weights or a spring motor when the stop mechanism controlling the rotatable gearing for operating the barrier is released by electrical means under the control of rail switches operated by a moving vehicle; or the release of the locking mechanism may be effected by mechanical means. In the arrangement shown, the barrier is in the form of a pole 4, rotatably mounted on a shaft 2 and provided with a counterweight 3. The loose pinion 5 is in gear with crown wheels 6, 7, which are movable in opposite directions. These wheels are respectively connected by ratchet members 8, 9 with sleeves 12, 13 having oppositelypositioned pawls 14, 15 engaging flanges 16, 17 on the shaft 2. Weights are carried by cords 19, 20, which are oppositely wound on the drums 12, 13. The arrangement is such that the cords may be wound on the drums to lift the weights manually by means of a crank fitted on the squared end 18 of the shaft 2. The wheels 6, 7 are prevented from rotating under the action of the weights by means of stop members 22 carried by a bent pivoted lever 25, the members 22 engaging with projections 21. When an electromagnet 29 is energized, as by a rail switch, the armature catch 28 is freed from the end of the lever, which is then moved by a spring 24 to bring the cut-away portion 23 of the pin 22 into the path of the pins 21. If the arm 4 is in the vertical position the wheel 6 is rotated to move it into the horizontal position. It is locked in this position by a projection 27 on the member 6 engaging the bent portion 26 of the lever 25 and depressing its free end into engagement with the armature catch, while at the same time the solid part of the pin 22 is brought into engagement with the next following pin 21. The vehicle next operates the switch controlling the movement of the wheel 7, the movement of this member restoring the arm 4 to the vertical position.
