Abstract: 762,842. Extruding. SCHLOEMANN AKT.-GES. Dec. 17, 1954 [Feb. 12, 1964], No. 36598/54. Class 83 (4). An excess-pressure protective device for a multi-cylinder hydraulic extrusion press, more particularly a cable-sheathing press, having a pair of billet receivers 2 arranged at an angle, preferably a right angle, to the axis of extrusion and whose rams 4 are operated simultaneously by hydraulic plungers 5, 6 in working cylinders 7, 8, comprises a pressure equalizer 60 which, upon a predetermined difference in pressure prevailing in the working cylinder spaces 10, 11, connects these cylinder spaces together for equalizing the pressures therein. The cylinder space 10 is connected by a pipe 30 to a cylinder 32 containing a plunger 34 and the cylinder space 11 is connected by a pipe 31 to a cylinder 33 containing a plunger 35. The plungers 34, 35 act upon equal arms 36 of a three-armed lever pivoted. about a fixed point 37. The other arm 38 of the lever extends between spring-biased valve plates 47 connected to cone valves 41, 42 which normally close communication between pressure spaces 43 and 45, and 44 and 46 respectively. Pressure space 43 is connected by pipe 40<SP>1</SP> to the pipe 30, and the pressure space 45 is connected by a pipe 49 to the pipe 31; the pressure spaces 44 and 46 are connected to the pipes 30 and 31 in a similar manner. Upon an excess pressure, for example 20 per cent, occurring in one cylinder space, such as 11, plunger 35 rises and moves the lever 36, 38 clockwise whereby the valve 41 is lifted from its seat to allow communication between the pressure spaces 43 and 45, thereby connecting together the cylinder spaces 10 and 11. In an alternative embodiment, Fig. 1 (not shown), the cylinder spaces 10 and 11 are connected directly to a spring-biased centralized piston valve which upon an excess-pressure occurring in one of the cylinder spaces is moved in one direction to connect together the cylinder spaces and vice versa.

Filed: 1928-12-13
Abstract: 302,290. Faberj, A. Dec. 13, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Manures.-Town refuse is converted into a nitrogenous fertilizer by treatment with hot sulphur dioxide. The gas is injected into a tower, divided into chambers, through which the refuse is passed downwards. Air inlets are provided and the dioxide is converted into trioxide, which with the moisture in the refuse yields sulphuric acid. This acid binds the nitrogen in the refuse. Excess sulphur oxide gases withdrawn from the top of the tower are passed into a calcium chloride solution. The solution is conveyed to a tower arranged between the sulphur furnace and the refuse-treatment tower, and the hot gases from the furnace carry the gases from the solution to the treatment tower. It is stated that an aqueous " sulphur-phosphor-potash " solution may be injected into the refuse under treatment. The treated refuse, preferably in admixture with phosphorite, is ground or crushed. Manure or sewage may be added to complete its fermentation.

Title: Valve mechanism for vehicle air springs
IPC: B60G17/052
Filed: 1959-11-06
Abstract: 876,051. Air-spring suspensions; adjusting body height BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Nov. 6, 1959 [April 20, 1959], No. 37719/59. Class 108(2). A vehicle air suspension comprises an air spring 10, a pressure reservoir 16, and a levelling valve 18 and is provided with means for conserving the air in the system during travel of the vehicle by disconnecting the levelling valve from the reservoir and from the air spring. The said means comprises a valve unit 24 and a two way valve 52. When the vehicle is in motion with the two way valve 52 connected to atmosphere, the valve unit 24 is as shown in Fig. 2, i.e. with check valves 66, 68 closed so that the reservoir 16 and the air spring 10 are disconnected from the levelling valve 18 and no air is transferred through the system. When the vehicle is stopped the valve 52 operates (e.g. in response to door opening and closing or brake application) to connect the control port 48 to the reservoir 16. The air pressure in the control port causes pistons 78, 80, in the unit 24, to move upwards unseating valves 66, to admit pressure to the supply port 40 of the levelling valve, and 68 to allow air pressure to flow from the air spring 10 to the supply and exhaust port 42 of the levelling valve. If the load on the vehicle now changes the levelling valve operates to restore the vehicle height. The valve 52 may be operable by mechanical, electrical or pressure means, and may operate in response to air pressure in the chamber of an air pressure actuated compressor unloader connected to the space above the pistons 78, 80. The latter are spring urged upwardly in this case, so that the air pressure acts on the pistons to maintain them in a down position with the check valves closed when the compressor is unloaded and allows the pistons to move upwardly to open the check valves when air is exhausted from the compressor chamber.

Abstract: 1,015,084. Metal strip feeds. I. PROPERZI. Sept. 25, 1963 [Oct. 6, 1962], No. 37782/63. Heading B3W. A device for forwarding a metal strip to a machine for performing an intermittent processing step comprises a curved former, a pair of curved arms pivotally mounted with respect to the former about an axis transverse to the direction of strip travel over the former with their free ends directed towards each other and defining with the former a space through which the strip may pass, and means for oscillating the arms to permit build-up of and subsequently express a loop of strip within the space, the means for oscillating the arms being adapted to be operatively connected to the machine for oscillation in synchronization with the processing step. Strip N from a continuous casting unit 1 passes through a tandem rolling mill 2 to the feed device A and then to a reciprocating press 4 which is driven from the last roll stand through a change-speed unit 13. The feed device A comprises a frame 23 in which reciprocates a slide 19 which is driven by a connecting-rod 24 mounted on an adjustable crank-pin 25, which is itself driven, by a shaft 5, from the press 4. Pivoted to the slide 19 are links 18 which are also pivoted to strip pressing arms 16 at the points 21. The arms 16 are also pivoted at the points 17 to supports 14, on which rests a curved former 15 over which the strip N passes. The movement of the slide 19 is synchronized with the press so that while the leading end of the strip is stationary in the press, the arms 16 are raised by the slide 19 and allow a loop of strip to form above the former 15 to accommodate the material which is forwarded continuously from the rolling mill. As the slide 19 subsequently descends the accumulated strip is fed forward to the press.

Title: Chloromethylphosphinic acid, salts thereof, and method of preparation
IPC: C07F9/48
Filed: 1961-10-23
Abstract: The invention comprises chlormethyl phosphinic acid and its salts of the general formula ClCH2.P(O)(H)(OY) wherein Y is a hydrogen atom, an alkali metal atom, e.g. sodium, or an ammonium radical. Chlormethylphosphinic acid may be prepared by the hydrolysis of chlormethylphosphonous dichloride ClCH2PCl2 in neutral to acidic aqueous solution, the reaction being preferably carried out in a non-oxidising atmosphere, e.g. of nitrogen.  It is preferred to use at least two moles of water for each mole of the dichloride and to use water containing hydrochloric acid as the hydrolysing medium. Preferred reaction temperatures are between 20 DEG  and 40 DEG C. and any excess water and the hydrochloric acid formed may be removed from the reaction mixture by volatilisation at about 40 DEG C. and a pressure of 1 to 2 mm. Hg.  The acid may be neutralised with various inorganic bases to form the salts, e.g. the acid may be dissolved in ethanol and neutralised with a strong sodium hydroxide solution to form the sodium salt.  Under strongly alkaline conditions the chlormethyl phosphonic acid may be hydrolysed to the metal salts of methyl phosphinic acid which may be chlorinated with SOCl2 to form methyl phosphonic dichloride which may then be reacted with methylphosphonic difluoride and isopropyl alcohol to form an isopropyl methylphosphonofluoridate.  Chlormethyl phosphinic acid reacts with an excess of ammonium hydroxide under reflux conditions to yield the ammonium salt of amidomethyl phosphinic acid and on treating the reaction mixture with an excess of sodium hydroxide and 2 molecular proportions of chlormethylphosphinic acid and then acidifying with HCl a trismethylenephosphinic acid amine product N[CH2P(O)(H)(OH)]3 is obtained which is an effective chelating agent for ferric ions in aqueous solution at pH 9,0 to 11,0.  The latter compound may be oxidised with air in the presence of mercuric chloride to yield the corresponding phosphonic acid which has a greatly enhanced chelating power for ferric ions.  The chlormethyl phosphinic acid and its alkali metal and ammonium salts are stated to be useful as antioxidant stabilizers for petroleum products. Chlormethylphosphonous dichloride is obtained by reacting ClCH2P(S)Cl2 with C6H5PCl2. Reaction may be effected under reflux in an atmosphere of nitrogen at 165-175 DEG C.
