Abstract: Relates to penicillins of the formula <FORM:0916205/IV (b)/1> wherein R1 stands for a hydrocarbon radical, optionally substituted, and the salts thereof.  Preferably R1 stands for an aralkyl radical such as benzyl or an aryl or alkyl radical, optionally substituted, for example an alkyl radical substituted by the A.CS.S-radical, where A stands for the radical of formula: <FORM:0916205/IV (b)/2> for example the A.CS.S(CH2)n-radical where n stands for an integer from 1 to 6.

Abstract: 1,039,712. Fluid pressure blasting devices. COAL INDUSTRY (PATENTS) Ltd. Nov. 23, 1962 [Nov. 24, 1961], No. 42103/61. Heading F3A. An infusion gun comprises jaws 18, 19 loosely held by a split sleeve 14 and capable of opening to engage the wall of the borehole when a central tube 12 is moved rearwardly relative to a tube 13. A resilient sleeve 7 is adapted to expand under pressure from the infusion liquid to seal the borehole ahead of the gun. In use, tube 12 is initially pulled rearwardly causing jaws 18, 19 to ride on a conical surface 10 and engage the wall of the borehole. After infusion, an explosive charge is fired, whereupon any tendency for the gun to move out of the borehole is resisted by the resultant movement of tube 12, causing further opening of jaws 18, 19. In a second embodiment, Fig. 3 (not shown), jaws 18, 19 are substantially as long as tube 12 and are pivoted at the rear end thereof.

[Also in Group XL (a)] Gases, e.g. contaminated gases escaping from leaks or safety valves in heat transfer circulation systems of nuclear reactors, are purified and cooled and in the case of steam condensed, by feeding them to an atomizer nozzle located in the upper part of a container partly filled with purifying and cooling liquid, e.g. water, the gases drawing liquid from the lower part of the container through a standpipe into the nozzle and the atomized gases being subsequently passed through the liquid for cooling and purification. As shown in Fig. 1, gas led from a heat-exchanger 2 draws liquid from the bottom of a container 19 into a discharge atomizer nozzle 23 and the atomized gas is then passed by throttling action through a pipe 24 to the lower end of a reflux cooler 20 disposed within container 19 and supplied at the top with cooling and purifying liquid through standpipes 25. Gas emerging from reflux cooler 20 is fed by pipeline 27 to a condenser or receiver 21, which may contain water for further purifying action, and the treated gas may be collected in a synthetic resin bladder 22 or blown off into space 12. In a modification (Fig. 2, not shown) an atomizer nozzle is directed at an angle towards the purifying liquid, either above or below its surface, in a partly filled container and towards a deflecting plate located whereby, after its downward passage through the liquid, the gas is deflected upwardly towards a discharge line.

Abstract: 946,248. Friction clutches. CREED & CO. Ltd. Nov. 22, 1962, No. 44204/62. Heading F2C. A coil-spring clutch cornprises a driving or driven drum 13 that is gripped by a self-contracting helical spring 10, the ends 11, 12 of which are respectively fast with a support 4 secured on a flange 1 of a driven or driving shaft 3 and a circumferentially movable element 18 on the flange 1, so that when means move the element 18 anti-clockwise relative to the flange 1 the spring 10 is unwound to release its grip on and contact with the drum 13. Brackets 7 support the spring 10 when expanded and a tension spring 30 between projections 19, 31 respectively fast with the element 18 and support 4 assists the engagement of the spring 10. In Fig. 10, wherein the shaft 3 is the driven shaft, the clutch is disengaged by moving a stop 24 into the path of the project 19 which is thus moved anti-clockwise relative to the flange 1 until it abuts a stop thereon to brake the driven shaft 3. A spring-loaded arm may be mounted on the stop 24 to engage the flange 1 and prevent reverse rotation thereof under the action of the springs when the stop 24 is moved into path of the projection 19. In Fig. 12, the clutch is disengaged by a plunger 29 which moves the element 18 anti-clockwise relative to the flange 1. The plunger 29 may be spring retracted and moved left for clutch disengagement by a solenoid 26 or vice versa. The drum 13 is connected to its shaft 23 through an Oldham coupling 32. The drum 13 is made of sintered metallic material having a lubricant content and has a helical groove thereon to permit the flow of lubricant. The direction of rotation may cause a self-tightening action of the spring 10.
