Title: Temperature Responsive Hydraulic System and Valve Means Therefor
IPC: F15B21/0423
Filed: 1967-09-11
Abstract: 1,193,718. Cooling hydraulic transmissions. ABEX CORP. 11 Sept., 1967 [13 Sept., 1966], No. 41451/67. Heading F2C. [Also in Divisions F4 and G3] In an hydraulic circuit comprising a motor 79 driven by a pump P, the oil leaving the motor normally returns to sump via line 80, valve 26, 29, line 82 and heat exchanger 83. However, some oil can return via orifice 32 and passages 36, 37, 45 and 46, and when the oil reaches a predetermined temperature, it acts on thermally-responsive element 40 and causes the latter to move valve member 39a further into bore 37b to restrict flow through the latter to build up pressure in chamber 30a to urge valve member 29 towards its seat to restrict flow through line 80. Some oil now flows through 81 to motor 84 to drive a fan 85 adapted to direct cooling air over heat exchanger 83. The quantity of oil by-passed through motor 84 is then controlled to maintain the oil temperature constant.

Title: Isolation of urokinase
IPC: C12N9/72
Filed: 1965-10-05
Abstract: Urokinase is purified by elution from a precipitate with a dilute aqueous solution of 6,9-diamino-2-ethoxyacridine. Alternatively, the urokinase and impurities may be absorbed on calcium phosphate gel in the presence of 6,9-diamino - 2 - ethoxyacridine and the urokinase alone removed by extracting with a phosphate buffer.  In a further alternative a urokinase-containing precipitate is washed with acidulated water at pH 3.2-5.5 and the urokinase then extracted with acidulated water at pH 1.5-3. Further purification is by adsorption on carboxymethyl cellulose followed by elution, dialysing and salting out which produces urokinase in crystalline form.ALSO:Purified crystalline urokinase free from pyrogens, thromboplastic substances and potentially antigenic impurities (see Division C3) may be used to treat intravascular clots in humans without producing allergic reactions.

Abstract: 982,364. Blasting-detonators. CANADIAN INDUSTRIES Ltd. Oct. 31, 1963 [Nov. 13, 1962], No. 43057/63. Heading F3A. A blasting-detonator, primarily intended for the detonation in bore holes of mixtures of ammonium nitrate and non-explosive fuels, comprises a metal casing 1, a compressed charge 2 of explosive such as P.E.T.N., a primer 3, a sealing element 6 consisting of a solid cylinder of deformable metal having a core of an essentially gasless combustible composition, and an explosive connecting cord 8 crimped in position to abut the sealing element 6 and having a core containing from 0À1 to 18 grains of high explosive per foot of length. The casing may be of aluminium or copper, the primer 3 of lead azide and the core of sealing element 6 of compositions which fuse on burning, such as mixtures of lead dioxide and silicon or red lead and silicon. The element 6, held in casing 1 by crimping or be adhesive, is conveniently made by charging and compacting the combustible composition into a lead tube, swaging the ends of the tube, drawing the tube down to the required diameter and cutting the tube to give elements of the desired length. A method of forming a sealing element having a helical core is also described. The connecting cord 8 is preferably one having a core-confining sheath of braided textile surrounded by a mantle of thermoplastics such as polyethylene or polyvinyl chloride and a core containing from 3À5 to 4À5 grains of high explosive per foot of length. As shown, the detonator is also provided with a delay train comprising a lead tube 4 containing delay mixtures such as silicon, selenium, red lead, lead chromate and barium chromate or red lead and silicon and a lead tube 5 containing a booster charge. In a second embodiment the primer is covered by a relatively insensitive ignition composition such as ground smokeless powder or a mixture of red lead and boron and the connecting cord, of smaller diameter than the casing, is held by a rubber plug crimped in the casing. Specifications 815,532 and 815,534 are referred to.

Abstract: 1441858 Tape dispensers SINGER CO 7 Oct 1974 [9 Oct 1973] 43321/74 Heading B8M In a printing, e.g. postage mailing, machine, a printing tape supply roll 12 is stored loosely within an open-sided compartment 14, resting on and against walls 18, 16. When the tape is withdrawn, advanced to a printing and cutting station (not shown) and then retracted, the sudden acceleration and deceleration of the roll movement is braked and dampened by the combined effect of the roll running up an inclined, resilient, spring 24 retained ramp 18 and a vertical braking plate in a bracket 22. Unnecessary unwinding of the roll and tape spillage and entanglements in the compartment are thus avoided. Tape 12 passes (and is initially threaded-up) around roller 26 and between manually operable friction rollers 30, 32.

Abstract: 1327589 Anti-skid systems; hydraulic systems ROBERT BOSCH GmbH 16 Sept 1970 [17 Sept 1969] 44114/70 Heading F2F An hydraulic braking system includes a spring biased ball valve 12, 15 interposed in a brake line 2 between a master cylinder 1 and a wheel cylinder 3 which ball valve 12, 15 is normally held open by a rod 13 of an actuating piston 7 but in the event of a wheel locking a solenoid valve 11 changes over and the piston 16 is made to move down causing the ball valve 12, 15 to close and the pressure in wheel cylinder 2 to be reduced until the wheel frees again when the parts return to their original positions. A tank 10 is connected via a pump 6 and a line 23 to a working chamber 22 above a spring biased safety piston 21 and in the event of the connection between the tank 10 and the working chamber 22 failing the safety piston 21 moves upwards under the bias of the spring 24 to act on the actuating piston 16 and cause it to move upwards to open the valve 12, 15 to ensure flow of brake fluid again in brake line 2 even if the pump 6 fails. As shown in Fig. 1 when the solenoid valve 11 changes over the pressure in a working chamber 17 below the piston 16 is relieved to the tank 10 and the piston 16 moves downwardly under the action of braking pressure. The safety piston 21 has a rod 20 projecting into the working chamber 17 which rod 20 is actuable on the underside of piston 16. In the embodiment of Fig. 3 (not shown) the actuating piston (27) is stepped so that a pump pressure lower than brake line pressure may actuate the piston (27), and a spill line (28) leads to the central portion of piston (27). In the embodiment of Fig. 4 an intermediate piston 31 is interposed between the actuating piston 16 and the safety piston 37 and the piston 31 has a rod 33 which sealingly enters a pressure-free chamber 32. On the wheel locking, the solenoid valve 34 changes over and pump pressure is fed to a chamber 35 above the piston 31 which is moved downwardly allowing the valve 12, 15 to close. If the pump fails the safety piston 37 is urged upwards by spring 24 and acts on the intermediate piston 31 whose rod 33 acts on the actuating piston 16 and opens valve 12, 15.
