Title: Improvements in or relating to automatic compressed air brake installations for railway vehicles
IPC: B60T15/18
Filed: 1962-11-29
Abstract: 1,012,449. Compressed air brakes. KNORR-BREMSE G.m.b.H. Nov. 29, 1962 [Dec. 2, 1961], No. 45247/62. Heading F2F. An automatic compressed air brake for rail vehicles which can be operated for single or multi-stage release comprises a two pressure control valve 7 actuated by the pressures in the train pipe 1 and an auxiliary reservoir 15, the control valve including a brake valve 31, 33 fed from the auxiliary reservoir, a release valve 25, 27 and an acceleration valve 37, 39. A venting valve 61, 67 is connected after the release valve and is operated by a piston system, 81 &c., loaded in the closing direction by a constant pressure, as from a reservoir 83, and in the opening direction by a pressure at least approximately corresponding, during the release operation to that in the train pipe and by the pressure from the control valve 7. A change-over device 51 is interposed between the release valve and the venting valve such that the former may be opened to the atmosphere directly for singlestage release or to the latter. A relay 93 pressurizes from a separate air reservoir 97 or vents the brake cylinder in accordance with the control valve and venting valve pressures. The system as shown operates in the following manner. On the venting of the train pipe 1, the pressure in chambers 5 and 41 of the control valve 7 decreases, a piston 9 being actuated by the auxiliary reservoir pressure to isolate chamber 5 from a chamber 11, the chambers being initially connected by a duct 17, to close the release valve 25, 27 and to open the brake and accelerating valves 31, 33; 37, 39, respectively. Compressed air from auxiliary reservoir 15 flows through the brake valve and line 89 to actuate the brake relay 93 and fill a further reservoir 91. Thus the pressure in the auxiliary reservoir falls, the piston 9 moving to an equilibrium position in which both the brake and release valves are closed. Also piston 81 is actuated by the pressure drop in the auxiliary reservoir to close valve 73, 75 and venting valve 61, 67. To release the brake in stages the train pipe 1 is pressurized to a level to produce the required release, piston 9 moving to open the duct 17 such that the release valve is opened and the auxiliary air reservoir again pressurized through duct 17. Piston 81 is actuated to open the venting valve temporarily depending upon the amount of pressurization. The brake is therefore released at a speed corresponding to the refilling rate of the auxiliary reservoir 15 and the venting rate of a nozzle 57.

Title: Production of polymeric cyclosilazanes
IPC: C08G77/60
Filed: 1965-10-27
Abstract: 1,130,375. Cyclosilazane polymers. MONSANTO CO. 27 Oct., 1965 [27 Oct., 1964], No. 45568/65. Addition to 1,085,012. Heading C3T. A polymeric cyclosilazane is made by treating an N,N<SP>1</SP>-disilyldiamine of the formula in which each of R<SP>1</SP> and R<SP>2</SP> is a hydrocarbon (h.c.) group of up to 8 C atoms or R<SP>1</SP> and R<SP>2</SP> taken together represent a polymethylene group and R<SP>3</SP> is an arylene, or a polyarylene-ether, -polyether, -sulphide, or -sulphone, or a divalent h.c. group, the R<SP>3</SP> group having not more than 24 C atoms, with a catalytic amount of an alkali metal, an alkaline earth metal or Al or a hydride or complex hydride thereof. When the arylene group is one in which the 2 N atoms of the diamines are separated by 2 C atoms or when R<SP>3</SP> is an aliphatic group such that the 2 N atoms are separated by 2 or 3 C atoms, the polymers produced are believed to have a ring structure different from that of the cyclodisilazanes of the parent Specification. Silanes of the formula R<SP>1</SP> 3 SiH may be used as chain terminating agents. If desired the silyldiamine may be formed in situ from R<SP>1</SP>R<SP>2</SP>SiH 2  and H 2 N-R<SP>3</SP>-NH 2 . The reaction is usually effected in an inert solvent and at 20‹ to 150‹ C. In a typical example (1) NaH was added to a dimethoxyethane solution of diphenylsilane and benzidine at 22‹ C, and after vigorous evolution of H 2  had subsided the mixture was heated to boiling until the reaction was complete, the yellowish polymer being subsequently isolated.

Abstract: 1527766 Bacterial oxidation of Fe<SP>2+</SP> in waste water DOWA MINING CO Ltd 17 Nov 1975 [30 April 1975] 47224/75 Heading C1C A process for the oxidation with iron bacteria of the Fe<SP>2+</SP> contained in mine, factory and other aqueous effluents at a pH so low as to provide little precipitation of basic salts, is characterized by comprising the following steps: passing the stream of waste water to be treated to an oxidation and culture zone which includes suspended beds of acid-resistant, porous and particulate material for the iron bacteria; oxidizing the Fe<SP>2+</SP> by agitating and blowing air into the waste water with particles suspended therein to culture the iron bacteria which inhabit the particles and utilize the Fe<SP>2+</SP> in the waste water as the energy source and at the same time to lower the Fe<SP>2+</SP> content of the waste water; transferring the treated suspension of the iron bacteria-bearing particles from the oxidation and culture zone to a sedimentation zone; recovering the Fe<SP>3+</SP> containing oxidized waste water in the sedimentation zone by separating the particles from the treated suspension; and returning the separated particles which the iron bacteria inhabit to the oxidation and culture zone. The effluent may have a pH of 2À0 or lower. Diatomaceous earth is a suitable porous material for supporting the bacteria. Acidic mine effluent is especially suitable for treatment in this way. The iron bacteria live in water and obtain the energy for maintaining their life by oxidizing Fe<SP>2+</SP> to Fe<SP>3+</SP>. They are often found in mine water.

Filed: 1972-10-20
Abstract: 1358337 Photo-mechanical cameras DAINIPPON SCREEN SEIZO KK 20 Oct 1972 48521/72 Heading G2A In a photo-mechanical camera, a length of film is drawn from a supply roll and conveyed by a perforated belt, on which it is held by suction, to the correct position for exposure. The roll of film (18), Fig. 1 (not shown) is in a cassette housed in the upper part of the camera and a length of film is conveyed downwards by a drive roller pair 21, 22 and a suitable length severed by a cutter (23). This length is now held and transported by a perforated endless belt 24 passing round rollers 25, 26, 27. The front part 24a of this belt is in close contact with the perforated front wall 15 of a suction box 14. The vacuum created inside this box by a pump 31 acting through a conduit 29 holds the film on to the belt. A pressure regulation valve 30 enables two different degrees of vacuum, a higher and a lower, to be applied. A motor 41 drives the perforated belt through a belt and pulley system 38, 37, 35, and also drives the feedroller 21 by a further belt and pulley system 36, 42, 43, 46, 48, 49. This latter system, however, includes a clutch 45, so that the drive can be broken. The various operations are controlled by a relay circuit 32 which itself is controlled by a cam drum 51, the drum having a number of grooves 52, 53, 54 which co-operate with a micro-switch 55 in the relay circuit. Initially the motor 41 is energized, so that film is conveyed between rollers 21, 22, belt 24 is driven, a low degree of vacuum is created in box 14, and cam drum 51 is rotated. The cam drum actuates the cutter to cut off a predetermined length of film, the motor being temporarily de-energized. The motor is then again energized but clutch 45 disengaged, so that the motor drives belt 24, but not roller 21. The film length is carried by belt 24 until it reaches the correct position for exposure, in alignment with the optical axis of the camera. The motor is now once more de-energized, so that the film remains stationary, and valve 30 switches over to the higher degree of vacuum, so that the film is held firmly in position while the exposure is made. The film is now passed downwards to fall into a collecting box.
