Abstract: 1,208,494. Railway systems. KLOCKNERWERKE A.G. 27 Feb., 1968 [28 Feb., 1967], No. 9371/68. Heading B7L. [Also in Division F2] In an apparatus for regulating the speed of a railway vehicle hydraulic piston and cylinder units 5 are mounted in a railway track and the pistons 7 are connected with movable abutments 8 for contacting the wheels of the railway vehicles for the transmission of kinetic energy to the rolling stock when it is moving below a target speed and removing kinetic energy from the railway vehicle when it is moving at a speed above the target speed characterized in that the units are mounted in cavities in the sleepers 3 or cross-ties forming part of the track. The apparatus also comprises upwardly-open dish means 15 arranged around the piston-rod 7 for catching oil which leaks past the seal around the piston-rod and transferring the oil to a leakage oil duct 14 provided in a channel member 12 adjacent to the track housing, the leakage oil duct 14 and the supply and return ducts 10 and 11 for a number of sleepers. Fig. 4 shows a further embodiment of the invention wherein each piston of the piston and cylinder unit 5 is associated with a pneumatic pressure supply means 22a, a pneumatic pressure control valve means 22 and pressure converter 21 having a pressure converting piston with a larger (26) and a smaller (25) face defining respectively parts of chambers 27, 24 respectively for air and liquid such that the pressure-converting piston is arranged to be subjected to air under pressure coming through the supply line 22a and the valve means 22 on its larger face 26 and having its smaller face 25 connected hydraulically through lines 71 with the piston 7 of the piston and cylinder control unit. The pneumatic pressure control valve means 22 is connected mechanically by means of a spigot 77 with the pressure converting piston 26 for the opening of passage means in the valve to connect the supply line 22a with the larger face 26 of the piston when the latter is moved in the direction to decrease the volume of the chamber 27. A non-return valve 72 is provided in the line 71 and a choke 73 is connected in parallel to it, the non-return valve 72 being arranged to check flow of liquid from the piston and cylinder unit 5 to the smaller face 25 of the pressure-converting piston and to be open for flow in the reverse direction. A duct 78 opens into the chamber 27 to allow air to escape from the upper end of the chamber when the control valve is in the position shown through a choke valve 81 to atmosphere.

Filed: 1917-07-09
Abstract: 107,977. Bouteille, J. July 7, 1916, [Convention date]. Diaphragm horns.- Relates to diaphragm horns or alarms for automobiles in which the diaphragm is operated directly by the action of an electromagnet, energized by an alternating current supplied by a rotary converter connected to a source of direct current on the car. The Specification as open to inspection under Sect. 91 (3) (a) describes also an arrangement, shown in Fig. 2 (cancelled), in which the coils 2. 3 of the electro - magnet are supplied with either form of current and are wound so as to neutralize each other. When inoperative, the contact 6, carried by the diaphragm 5, engages the adjustable contact 7 thereby short-circuiting the coil 3 when the diaphragm is attracted to the electro-magnet. This movement separates the contacts 6, 7, when the diaphragm retracts under its own elasticity owing to the coils 2, 3 being in opposition. Sparking at the contacts 6, 7 is reduced by connecting these contacts through a resistance 8. This subjectmatter does not appear in the Specification as accepted.

Title: Recovery of cellulose acetate from acetic acid solutions thereof
Filed: 1930-03-28
Abstract: The precipitated acetate is separated acetic acid liquor, containing about 50 per cent acid, obtained by precipitating cellulose acetate from its solution in acetic acid by addition to an aqueous bath is suitably concentrated e.g. by mixing with ethylene dichloride and distilling an azectropic mixture of water and ethylene dichloride.ALSO:Cellulose acetate is precipitated from acetic acid solutions thereof, in the form of soft clumps, fibres or shreds which can be readily disintegrated and washed, by introducing the solution into an aqueous bath containing initially at least 20 per cent by weight of acetic acid.  The final concentration of acetic acid may rise to 50 per cent without impairing recovery of the acetate.  In an example 275 parts of a reaction mixture, containing over 38 parts of cellulose acetate and 237 parts acetic acid, are poured with vigorous stirring into 650 parts of an aqueous acetic acid solution of 35 per cent strength.  The precipitated acetate is separated and washed; the acid liquor, containing about 50 per cent acid, is suitably concentrated e.g. by mixing with ethylene dichloride and distilling an azeotropic mixture of water and ethylene dichloride.  In a second example water is introduced into the aqueous bath concomitantly with the reaction mixture so as to maintain the acetic acid concentration more nearly uniform, the initial concentration being 33 per cent and the final about 40 per cent.
