Title: Improvements in or relating to breathing apparatus
IPC: B63C11/22
Filed: 1957-12-27
Abstract: 885,204. Respiratory apparatus. NOVELLI, A., and BUGGIANI, P. Dec. 27, 1957, No. 40173/57. Class 81 (2). Underwater breathing apparatus includes a demand controlled gas supply regulator between a source of gas and a mouthpiece or face mask and an exhaust valve which is opened against a yielding control during but after the beginning of exhalation through a mechanical connection by a control member of the regulator. The mouthpiece 14 communicates with the demand regulator through intercommunicating chambers 15, 16, a passage 20, a cylinder 2 in which the exhalation valve comprising a plate 7 and a seat 5 is located, and a flexible hose 3. The sheath 11 of a Bowden transmission interconnects the valve 7 and one portion B of the regulator, the cable 10 interconnecting a cap 9 of the cylinder 2 with another portion A of the regulator. On exhalation gas first passes from the mouthpiece to the regulator for re-use and moves portions A, B apart so that the exhalation valve is opened against a spring 13. Thus gas exhaled after exhalation has begun passes to the surrounding water through the exhalation valve and openings 8 in the cylinder 2. A piston 21 may be moved to block communication between the mouthpiece and the regulator and exhalation valve and to enable the user to breathe atmospheric air through a pipe 19. In a modification, the Bowden transmission is connected so that during exhalation the sheath moves to pivot a bell-crank lever (not shown) against a spring to open the exhalation valve. In an alternative construction, the demand regulator comprises a bellows with relatively movable plates 37, 38 (Fig. 5). An inlet valve 48 and an exhalation valve 47 are arranged in a housing 40 carried by one plate 37 to establish communication between the bellows and a gas supply and a vent pipe 42, respectively. A lever 49 pivotally mounted on the valve housing is located inside the bellows, one end of the lever engaging an eye 51 on the other plate 38. The lever is pivoted to open the inlet valve during contraction of the bellows on inhalation, and to open the exhalation valve, during expansion of the bellows on exhalation, against springs 54, 53, respectively. The vent pipe which has a tendency to float may have a duck bill issue valve on its end.

Filed: 1965-09-23
Abstract: 1,121,762. Making hollow bodies by winding. UNITED AIRCRAFT CORP. 23 Sept., 1965, No. 40597/65. Heading B8G. Means for winding filamentary material on to a rotating and irregularly shaped mandrel comprises an endless chain 43 passing over at least three sprocket wheels 37, 39, 41, a carriage 47 carrying a filament guide for traversing the filamentary material on to the mandrel, and a sliding connection between the carriage 47 and the chain 43 such that as said connection moves with the chain it causes a traversing motion of the carriage 47 whilst following those paths of the chain 43 that have a component of direction parallel to the axis of the mandrel. In Fig. 2, the sliding connection can move up and down the carriage 47 and the carriage will perform a traversing motion whilst the sliding connection is following any path of the chain except the path 69 between the sprocket wheels 37, 45. The horizontal paths of the chain cause maximum traversing speed of the carriage 47 and the inclined paths of the chain cause reduced traversing speeds of the carriage. The chain path 67 causes a temporary reversal of direction of traverse approximately half way along the traverse stroke controlled by the lower half of the chain. The setting of the sprocket wheels is adjustable in the vertical slots 33, and the slots 33 may be formed in a single plate or in a plurality of plates 31 that can be selectively spaced apart along rails 26, 28. The apparatus may be used in the fabrication of rocket engine casings wherein glass fibres or similar filaments are wound over a removable mandrel while a thermosetting resin is applied to the filaments, the resin being cured on completion of the winding operation. The resin may be an epoxy resin.
