Title: Improvements in or relating to respiratory apparatus
IPC: A62B9/02
Filed: 1961-09-04
Abstract: 923,990. Respiratory appliances. O. H. DRAGER, [trading as HEINR DRAGERWERKE & BERNH DRAGER]. Sept. 4, 1961 [Sept. 2, 1960], No. 31785/61. Class 81 (2). In a closed-circuit breathing-equipment a pressure-sensitive device, influenced by pressure within the circuit, controls a closure means which arrests flow around the circuit and also controls an oxygen supply valve. In one form, exhaled gas from a mask passes through a duct 1 to a carbon-dioxide absorber 2 and thence to a breathing-bag 4 leading through an inhalation valve 7 back to the mask. A diaphragm 15 is mounted across the duct 3, leading from the absorber to the breathing-bag so that, when the user inhales, the pressure difference moves the diaphragm towards the right whereupon a spring-loaded valve 17, carried by the diaphragm, is opened by striking an adjustable stop 20. At the same time a bridge member 18, also mounted on the diaphragm, opens a tilting valve 23 to admit oxygen to the system from a pressure regulator 10 and supply cylinder 8. In modifications the diaphragm assembly is located to replace the inhalation valve while in one of these the valve comprises a seating mounted on the diaphragm and normally closed against a fixed stop, so as to be opened on movement of the diaphragm.

Title: Improvements in or relating to photographic roll film cameras
IPC: G03B1/48
Filed: 1953-11-17
Abstract: 780,247. Photographic cameras. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE FABRIK PHOTOGR. PRAZISIONS-APPARATE]. Nov. 17, 1953 [Aug. 17, 1953], No. 31852/53. Class 98(1) In a roll-film 'camera having a resiliently mounted perforated presser plate and a bellows producing suction to hold the film flat, the bellows is latched 'in the compressed state on winding the film and, the latch is released on operating the shutter release button, the resilience of the bellows performing the actual shutter release operation simultaneously with its own expansion. Preferably, the bellows is carried on the presser plate which is moved rearwardly, on winding the film, to compress the bellows against the rear wall of the camera. As shown, presser plate 13 is moved rearwardly on actuating film winding handle 53 by bar 31 and a parallel linkage arrangement (Fig. 5, not shown), and, when the bellows 49 are compressed, latch 50 engages catch 53. On the return movement of the plate 13 under the action of springs the latch 50 rises over and snaps down behind the hook 54 of a draw-bar 55 without becoming disengaged from catch 53. The film may then be exposed by moving shutter release 58 clockwise about fixed pivot 72. This action turns lever 66 about fixed pivot 65 and raises the hook end of draw-bar 55. Immediately the latch 50 is raised clear of catch 53, the bellows springs open carrying with it the drawbar 55 and completing the movement of the shutter release lever 58. The inclined surface 73 of the slot 69 co-acts with the pin 68 on completion of the shutter release and imparts a downward movement to the hook end of draw-bar 55 which is thereby disengaged from latch 50. A weak return spring 70 brings draw-bar 55 back to the position which it occupied before commencing the exposure. A stop (not shown), is preferably provided so that the release lever 58 cannot be moved sufficiently far to release the shutter.

Title: A combined accelerator and brake control for a motor vehicle, and a motor vehicle incorporating the same
Filed: 1963-08-13
Abstract: 1,059,958. Controlling motor vehicles. T. FUKUDA. Aug. 13, 1963 [Aug. 25, 1962], No. 31874/63. Heading B7H. [Also in Division F2] A combined accelerator and brake pedal arrangement for a motor vehicle comprises a pivoted control pedal 2 with a braking projection which continuously engages a vehicle braking lever 11 and an accelerator projection 5 which engages a vehicle throttle control lever 7 only in an accelerator control range of pedal 2, in which range the braking projection engages a portion c of the braking lever 11 profiled as the locus of movement of the braking projection so that lever 11 remains stationary, the arrangement being such that as the pedal is pivoted clockwise the brakes are progressively released through the braking range and the throttle opened progressively through the accelerator control range. The braking projection is coaxial with projection 5 but on the opposite side of extension 4 of the pedal 2. The braking range (p) (Fig. 2, not shown) is preferably separated from the accelerator range (r) by a neutral range (q). When the heel of the pedal 2 is depressed projection 6 of the pedal 2 rotates the lever 11 clockwise about pivot 12 and hence opens a cock 21 in a conduit 20 connecting vacuum cylinder 18 to the vehicle engine inlet manifold and thus drawing to the right both the piston in the cylinder 18 and, through link 19, lever 16 which displaces hydraulic fluid from master cylinder 17 to apply the brakes. When the pedal toe is depressed in range p, projection 5 engages limb b<SP>1</SP> of lever 11 rotating the lever anticlockwise and closing cock 21 when a spring 22 in the cylinder 18 returns brake lever 16 to the brake released position. On further depression of the pedal, in range r, projection 5 engages portion c of the lever 11 to hold the cock 21 closed and also engages limb a<SP>1</SP> of the throttle lever 7 to control the engine speed through rod 8. The centre of curvature of portion c when engaged by pin 5 is coincident with the axis of the pedal pivot 3 so that movement of the pedal in zone r maintains the brake released while controlling the throttle lever. The neutral zone q permits slow running of the engine without brake application. In an alternative (Fig. 3, not shown), leg b of the lever 11 operates an hydraulic master cylinder directly.

Abstract: 951,132. Extensible paper. BELOIT IRON WORKS. Sept. 5,1961, No. 31882/61. Headings D2A and D2B. In order to produce a smooth-surface fibrous crÛped web, a web from a wire-cloth 19, Fig. 1, of a Fourdrinier paper-making machine is couched at M, passed through the nip of a suction wet press 12 and crÛped off the upper press roll 26 by a doctor 31, the crÛped web falling on to a slower wet press felt 32 which carries it through a second wet press 13 where the web is flattened. The flattened web passes over dryer rolls 40, through a breaker stack having rubber-covered rollers 41, over further dryer rolls 42 and is reeled at 17. The crÛping and flattening and hot pressing cause the longitudinal fibres to be curved as illustrated in Fig. 11, i.e. convex upwardly at 55, concave at 56 and 'S' curved at 57 thereby increasing the longitudinal extensibility of the web. The web may include thermoplastic binders. In modifications, the wire-cloth 19 runs about a return roll, the web being taken off the stretch of the wire between the couch and return rolls with the aid of an air or water jet or by a suction pick-up roll: in the latter case, the web is creped from a lower, plain roll of the first wet press, the top roll of which is a suction roll.

Title: Improvements in or relating to phase multiplying transformers
Inventor: STARR ARTHUR TISSO
IPC: H01F30/14
Filed: 1947-12-04
Abstract: 640,100. Transformers. STANDARD TELEPHONES & CABLES, Ltd. Dec. 4, 1947, No. 32034. [Class 38 (ii)] [Also in Group XL (c)] A static phase-multiplying transformer for producing a sine wave polyphase output comprises a first core carrying a polyphase primary winding producing a rotating magnetic flux and a second core carrying a secondary winding having a greater number of phases than the primary, the cores being angularly adjustable to displace the secondary output phases relative to the primary phases. A two-phase primary winding is wound in slots 4, 5 and 6, 7 the secondary winding being wound in slots 8, 9 to 15, 16 giving a normal four-phase winding. By placing two windings in one slot and making certain connections with a 180 degree phaseshift an eight-phase winding may be obtained which can be either star or ring connected. By further doubling the windings per slot two separate secondaries may be had which if connected one in star and the other in ring fashion produce a sixteen-phase output. This result may also be obtained by a single coil per slot, each centre-tapped to provide the starpoint 21 and having two further tappings, e.g. 22, 26, eight phases then being taken from tappings 22-29 and another eight phases from 30-37. The ratio between windings 21, 22 and 21, 17 must be 1: 1.307 in order that all the sixteen-phase voltages may be equal. The relative phase relationships between primary and secondary windings may be varied by angularly adjusting the core 10 relative to core 3 which movement may be effected manually or automatically. Any number of primary and secondary phases may be employed and the rotation may be limited by stops, or unlimited movement may be had by the provision of brushgear. The transformer is particularly useful in multiplex pulse transmission systems to avoid phase distortion due to the time lag between the transmission and reception of signals.
