Title: Improvements in or relating to Steering Apparatus for Motor Vehicles.
Inventor: SCHERL AUGUST
IPC: B62D1/26
Filed: 1916-11-24
Abstract: 102,385. Scherl, A. Nov. 24, 1915, [Convention date]. Guiding road vehicles by rails and like guides; controlling independently of drivers. - Motorvehicles are provided with a depending arm which controls the steering-mechanism, and can be depressed to engage a rail in the road, the hand-wheel steering- mechanism being then disengaged. The rail arm is elevated by releasing a spring and is depressed by hand, the hand-wheel mechanism being put into operation when the arm is raised. In a modification, the rail-arm is also raised and manual steering restored on meeting an obstruction on the rail, means being provided for shortcircuiting the ignition in such an event. The arm 5, Fig. 3, is mounted on an horizontal member 12 and is provided with a roller 4 riding on the rail 3. The rail-arm is normally pressed down by coiled springs and is elevated by a lever 29 actuated by a rod 30. The member 12 is provided with a rearward extension 16 which engages the cross-connexion 20 of the steering-mechanism. The operating-rod 30 is connected to a bell-crank lever 37, 38 connected to a hand-lever 31 by a link 35. The rod 30 is under the influence of a spring 39, which raises the depending arm 5 when released by a pawl 42 operated by a pedal 48. The hand-wheel steering-connexion is effected through a camactuated sliding member operated by a lever 50 connected at 51 to the rod 30, the arrangement being such that, on the depression of the railarm 5, the hand-wheel connexion is broken, and vice versa. In the form shown in 'Figs. 7 and 8, the lever 29 is connected to a bracket 70 by toggle-links 74, 75 provided with a pin which is engaged by a catch 72, which can be retracted by the pedal 48 through a lever 84 and cable 83. On the retraction of the catch 72, the spring 39 effects the raising of the rail-arm. The catch 72 is also retracted, when a member 6 in front of the rail wheel 4 meets an obstruction. The member 6 is provided with an arm 87 which operates a link 90, the end of which engages one arm 92 of a cranked lever, the other arm 78 of which is connected with the catch 72. In this form, the arm 38 is connected to a member 105 which operates an electric contact 111. On the railarm being raised through meeting an obstruction, the contact 111 is moved and short-circuits the ignition. If the rall-arm is raised through the depression of the pedal 48, a cam 121 breaks the connexion between the member 105 and the electric contact, so as to render the member 105 inoperative, and the ignition circuit is not broken.

Title: Purified sarkomycin, its derivatives and a method for preparing them
Filed: 1956-06-04
Abstract: The anti-tumour antibiotic sarkomycin (2-ethenyl - 3 - carboxycyclopentan - 1 - one) is purified by treating a solution, e.g. an aqueous solution of sarkomycin or an alkali metal or alkaline earth metal salt thereof, with copper <PICT:0828807/IV (b)/1> <PICT:0828807/IV (b)/2> ions, e.g. cupric sulphate or cupric acetate and then liberating the sarkomycin from the copper salt so produced by treatment with (a) hydrogen sulphide, or (b) a cation ion-exchanger, e.g. amberlite IR-120 (H form).  The filtrate of (a) and the eluate from (b) is then extracted with a water-immiscible solvent such as ethyl acetate and sarkomycin recovered by removing the solvent in vacuo.  Crude sarkomycin contains two groups of components: (a) sarkomycin-S consisting of two or more molecules of sarkomycin joined by an -S-S- linkage (sarkomycin-S1) or a -S- linkage (sarkomycin-S2), and (b) sarkomycin-E consisting of polymers of sarkomycin, e.g. the dimer is sarkomycin E1.  The components of sarkomycin are separated from solutions of the copper salts by means of (a) the difference in distribution coefficient between two solvents, (b) dialysis, and (c) adsorption on active carbon, alumina or silica gel.  Using a mixture of water and a water-immiscible solvent such as an ester of a fatty acid having up to 5 carbon atoms, butanol or isoamylalcohol, the copper salt of sarkomycin-S goes into the aqueous solvent and the copper salt of sarkomycin-E into the organic solvent.  After regeneration, sarkomycin-S may be separated into sarkomycin-S1 and -S2 by selective crystallization from solvents.  Both sarkomycin-S1 and -S2 are acidic forming salts with alkali or alkaline earth metals.  They are soluble in ethyl acetate, acetone and butanol but insoluble in chloroform, benzene and petroleum ether. <TABS:0828807/IV (b)/1>

Abstract: 646,790. Magnetic-separators. PLANIOL, R. July 2, 1947, No. 17460. Convention date, Sept. 21, 1945. [Class 72] In a method of and apparatus for magnetic separation wherein particles are subjected to centrifugal force in a magnetic field, the material is hurled outwards to disintegrate agglomerations of particles prior to the magnetic separation by means of a centrifugal force independent of that to which the particles are subjected during the magnetic separation. The disintegration and separation may be effected under vacuum. Material falls upon the rotating disintegrator plate 65 having ribs 71 where it is disintegrated and hurled outward on to the plate 21 of the feed rotor 20 which in turn hurls the material at high speed through the peripheral nozzle 22 into the space between a flange 42 attached at 46 to the rotor 20 and a pole shield and web 27, 32. The parts 32, 42 rotate in the narrow air gap G between an upper flatfaced pole 15 and a lower pole with one or more annular corrugations 16-18. Magnetic particles are deflected downwardly, and being intercepted by the edge 35<SP>1</SP> of the interceptor cone 35 fall and are urged downward by inclined vanes 40 attached to the skirt 33 of the web 32 into the annular space 38 for collection at 62. Non- magnetic particles pass over the edge 35<SP>1</SP> and similarly fall and are urged downwardly by inclined vanes 43 attached to the flange 42 into the space 39 for collection at 63. Inclined vanes 55, 56 carried on rotating arms 57 further urge the particles downwardly through the ports 62, 63. The interior of the separator may be exhausted by a pump attached to a port 64. The feed motor 20 is driven through a pulley 26 (2,500 r.p.m. or more); the disintegrator plate 65 through pulley 70 (3,000 r.p.m. or more); the pole shield 27, 32 through pulley 34 (6,000 r.p.m. or more); the arms 57 through pulley 61.

Abstract: 593,230. Gas-blast switches. GENERAL ELECTRIC CO., Ltd., and KEELEY, F. J. July 11, 1945, No. 17696. [Class 38(v)] In a pneumatically-actuated, air-blast circuit-breaker the two sides of a contactoperating piston are subjected respectively to the pressure of air in a receiver and in a cylinder, and the piston controls a valve normally closing the air-blast passage and maintaining a pressure difference between the two sides of the piston whilst pressure is maintained in the cylinder, means being provided to release the pressure in the cylinder to cause the contacts to separate. Compressed air is supplied to a receiver 1 and cylinder 9 through pipes 8, 22. When air is released from the pipe 22, air pressure in the receiver acts on the outer portions of piston 12, 13, overcoming springs 23 and moving the pistons. Sealing rings 21 on the pistons then separate from flanges 10, and the pistons accelerate as larger surfaces are exposed to the air pressure. The contacts 7 are biased by springs 18 so that they do not follow the pistons until plugs 16 secured to the contacts are engaged by flanges 17 on tubes 14 secured to the pistons, by which time adequate pressure for arc-extinction has been built up in the tubes 5. A series isolator is opened as soon as the current has been interrupted and air is re-admitted to the pipe 22 to close the contacts 7, 6 and conserve compressed air.
