Title: Improvements in or relating to forced flow vapour generating systems
IPC: F22B29/02
Filed: 1962-07-27
Abstract: 1,007,609. Critical pressure boilers. SULZAR FRERES S.A. July 27, 1962 [July 27, 1961], No. 29029/62. Heading F4A. In a forced flow vapour generator operating at supercritical pressure working medium is recirculated at part load so that at all loads the transition zone of liquid to vapour is located in the heating surfaces of the combustion chamber. A feed pump 19 supplies working medium through an economizer section 20 and pendent tubes 24, 25 to headers 26, 27 from which the medium flows to a mixing vessel 30 before flowing to centrewall tubes 34 which are disposed as a partition in the combustion chamber 11 and which extend in vertical parallel relation between headers 32, 35. From the header 35 the medium flows to and through wall lining tubes 40 which also extend vertically and in parallel between inlet headers 37, 39 and an outlet header 41 which leads to a distribution header 42. From this point some of the working medium flows through superheating sections 52, 57, 59 in series to an H.P. turbine stage 61, and then via a reheater 62 to L.P. stage 64. The remaining portion of the medium is recirculated from distribution header 42 by a pump 45 and mixes with the fresh feed in the mixing vessel 30 before passing through the centre wall and water wall tubes 34, 40 in series. The amount of working medium recirculated is controlled in dependence on the load on the generator so that the transition zone at all loads is kept within the heating surfaces in the combustion chamber 11.

Abstract: 1,195,291. Semi-conductor devices. S. F. KAUSOV. 23 June, 1967, No. 29124/67. Heading H1K. Semi-conductor devices having PN junction areas considerably smaller than the ohmic contact areas are made by providing metallized opposite surfaces of a wafer, e.g. of Si, having a junction 4, with regions 5, 6 of acid-resistive protective material in such a way that the orthogonal projections of the regions 5, 6 only partly overlap. When the wafer is etched from both sides to a depth slightly beyond the junction 4 individual devices such as the diode of Fig. 3 are formed. Matrices of diodes may be formed by shaping the protective regions 5, 6 as mutually perpendicular sets of strips.

Abstract: 1,223,675. Guns; projectiles. ETHER ENG. Ltd. 21 June, 1968 [23 June, 1967], No. 29133/67. Headings F3A and F3C. A gun comprises a tubular barrel 10 of which the ends are initially sealed by disruptable closure members 17, 18, means 50 for withdrawing air from the barrel and means for disrupting one of the closure members whereby a projectile 26 fitting slidably within the barrel is accelerated towards and through the other closure member and out of the barrel. The disruptable closure members 17, 18 may be thin membranes of synthetic plastics material and the means for disrupting a closure member comprises a ring 21 carrying at its periphery a plurality of blades 22. In the construction shown the ring 21 is provided with a plurality of guide pins 23 which co-operate with inclined slots in the collar 20 of a closure member clamping member 19. Rotation of the ring 21 by a solenoid actuator (Fig. 3, not shown) drives the blades towards and through the closure member 18. Closure member clamping rings may be screwed on to the barrel (Fig. 4, not shown) or be secured by fluid pressure means. The barrel may be extended by a further tube having a restricted outlet at the end opposite the barrel such that a projectile may be brought to rest in the further tube (Fig. 5, not shown). The projectile 26 is mounted in a sabot 27 of a low density material such as expanded polyurethene or wooden materials, through a load distributing plate 2 and two radial supports 30, 31. To separate the projectile from the sabot 27 a separator 32 is mounted adjacent the muzzle of the gun. The projectile may be in three parts, the device to be tested at the forward end thereof, a main body portion and a collapsible structure interposed therebetween. The main body may be connected to the firing point by an electrical cable (Fig. 6, not shown) or the main body may house a tape recorder (Fig. 8, not shown) or a transmitter (Fig. 7, not shown).

Abstract: 261,773. National Cash Register Co., (Assignees of Goldberg, M. M.). Nov. 21, 1925, [Convention date]. Cash registers with operating- means.-A differentially-set machine is provided with a particular construction of means for turning the indicator drums directly from the old position to the new. The setting- levers each carry a U-shaped bracket 45 to frame an index digit and this bracket is mounted on a spring- controlled lever 34 provided with a pawl 35 to engage teeth on a fixed segment 38, so that prior to the positioning of the setting- lever the bracket must be depressed to free the pawl from the segment. The levers are returned to normal position by the action upon tails 98 of roller-carrying levers 95 secured to a shaft 94 carried by frames 91 fast to the main shaft 49. During the forward stroke of the operating lever the rollers 97 on the levers 95 are prevented from engaging the tails by means of a switch-over cam 107, Fig. 3, serving to guide a roller 100 on an arm 99 fixed to the shaft 94. The setting-levers 30 are held in their adjusted positions throughout the forward stroke by means of aligning pawls 50, Fig. 5, pinned to a shaft 52 rocked by a bellcrank 55 by means of an arm 58 fixed to the main shaft 49 and having a cam groove 57. The pawls 50 are rendered operative in the forward stroke and at the commencement of the return stroke are disengaged owing to the action of a switchover flanged rocker 60 co-operating with the groove. Differentially-moved indicators.-Each setting- lever 30 has rack teeth 70 to gear with a floating pinion 71 carried by a bell-crank 72 pivoted en the central rod 31. The pinion meshes also with teeth 73 on a plate 74 toothed at 76 to drive the indicator drums 80. The pinion 71 is displaced by the action of setting and is restored to its zero position, to convert the old to the new indication. by means of the rocking-frame 91 provided with cam edges 92, 93 adapted to engage a roller 90 on the rear arm of the bell-crank. The plates 74 are aligned and held by pawls 75 rigidly mounted on the shaft 52 the plates thus being free to move only during the forward stroke of the operating-lever. The Specification as open to inspection under Sect. 91 (3) (a) also contained the subject-matter of Specifications 268,376 and 268,377.
