Abstract: 516,951. Internal expanding brakes. AUTOMOTIVE PRODUCTS CO., Ltd., GATES, G. R. G., and SIDNEY, W. E. Aug. 3, 1938, No. 22984. [Class 103 (i)] A vehicle brake adapted to be operated by hydraulic or mechanical means comprises .a member which acts in tension to move the brake shoe or shoes outwardly into contact with a rotating drum, the member being connected by a lost motion device with the piston of a hydraulic cylinder unit, and by a second lost motion device with mechanical brake rigging. In the construction shown in Fig. 2, brake shoes 12, 13 are adapted to be pressed outwardly by means which include plungers 39, 40, pivoted sector-shaped members 35, 36, and a tension rod 32. The rod 32 passes through an extension 20 of a piston 19 and at its inner end is screw-threaded to receive a collar 30. The collar is connected by a pin 31 to a tubular shell 26 which is flanged at both ends. At one end it is provided with a collar 51 against which bears the head 50 of a rod 48. The rod is screw-threaded at 49 for attachment to a mechanical brake rigging. The shell 26 is adapted to have limited sliding movement within anenlarged portion of a cylinder 17. When the brake is operated hydraulically the piston 19 acts through the flange 29 to move the collar 30 within the shell 26. Mechanical operation is transmitted through the shell 26 and flange 29 without affecting the piston 19. The collar 30 of the tension rod 32 is formed with a diametral slot for engagement by a ridge 53 on the rod 48, whereby the position of the tension rod may be adjusted. In a modification shown in Fig. 3, the piston 19 is normally held in its inoperative position by a spring 63. The rod 48 is fixed to a shell 26a which is flanged at 29a to engage a collar 58 fixed to the tension rod 32. Specification 495,834 is referred to.

Title: Method for purifying the electrolytes used in the electrolysis of alkali metal chlorides employing a mercury cathode
IPC: C01D3/16
Filed: 1945-09-07
Abstract: Electrolytic cell liquor containing alkali-metal chlorides is purified by passing at 10 DEG -100 DEG C. through a layer of porous carbon such as active carbon, charcoal or coke to eliminate free chlorine and hypochlorites.  To remove the chlorates present oxidisable substances such as ferrous chloride may be added to the liquor together with hydrochloric acid.  Catalysts such as oxides or hydrates of iron may be added to the liquor or carbon to accelerate the reactions.  Partial dechlorination may be effected by passing finely divided air or other inert gas through the liquor which may be first acidified with HCl the liquor being then treated as above.  The chlorinated gases from the partial dechlorination may be passed upwardly through porous carbon as water streams down to produce HCl. This latter contains free chlorine and is passed through further carbon to transform completely the free chlorine into HCl.

Title: Improved means for mooring submarine mines or the like
IPC: F42B22/16
Filed: 1919-09-27
Abstract: 167,506. Buddicom, H. W. Sept. 27, 1919. Mines, marine.-Relates to mooring-devices comprising an anchoring cable-drum a which sinks to the sea bottom with the mine, whereupon the cable is automatically released to enable the mine to rise, the paying-out of the cable being arrested when the mine reaches a predetermined depth below the sea level. According to the invention, the depth at which the mine is moored is determined by a float e moving within a diving-bell like chamber c on the drum. The float rests upon a screwed collar v which is initially raised to suit the predetermined depth by turning a screw f through hand gear m, n. The float is in two halves encircled by rubber bands and kept out of engagement with the screw f by collars h, h<1>, Figs. 3, 4, and 5, which tend to separate under the action of springs i. As the mine sinks, the float rises freely on guides g until the sea bottom is reached, when the collars h, h<1> are released to enable the two halves of the float to grip the screw. The collars are released by rotation of the guides q to the position shown in Fig. 4, as the drum starts to revolve, the guides being further rotated to the position shown in Fig. 3 to enable the two halves of the float to come together. As the cable pays out, the drum a, the guides g, and the float e are rotated, the float descending on the screw f until projections u engage ratchet teeth on the collar v and cause a clutch p on the collar to grip the screw and turn it. This movement of the screw operates through the gear n, m, pinion w, and toothed sector x, to move a stop y into engagement with teeth z on the drum to arrest it. In a modification, the two halves of the float are kept apart by_soluble plugs.
