Abstract: 393,540. Changing signs. NEWS PROJECTION CORPORATION, 44, Whitehall Street, New York, U.S.A. Jan. 28, 1933, No. 2772. Convention date, Jan. 29, 1932. [Class 3 (i).] Optical-projection apparatus.-In a combined stock-quotation ticker and optical-projection apparatus, the tape is drawn freely from the ticker during both the printing operations and the periods of rest of the latter by means of a continuously-driven tape-pulling device disposed between the ticker and the projection apparatus, and which dissipates the vibrations transmitted to the tape by the ticker, and a second tape-pulling device or rewind reel is disposed beyond the discharge end of the projection apparatus to pull the tape across the light aperture of the latter. The tape 4 of a ticker 3 is drawn from the latter by means of roller 5 and a co-operating spring-pressed roller 6, both rollers having narrow contacting faces to prevent blurring the printed tape, and the former roller being driven by a motor 36 through a belt and pulley. and reduction gearing. The tape 4 is drawn across the light aperture 10 of a projection apparatus by means of a rewind reel 11 driven at a rate slightly faster than the roller 5 by a motor 15 through a spring belt 16 or other slipping device. The tape passes in a straight line from the ticker 3 to and across the light aperture 10 with the print facing upwardly, and the image is projected through an objective lens 18 on to a mirror 20, then deflected on to a mirror 21, and finally deflected on to a screen 22. Preferably the light aperture is provided with rollers 23, 24 to support the tape 4. Vibration in the tape is stated to be negligible on account of the elasticity of the tape, the yielding nature of the printing type in the ticker, and the short duration of the printing operation of each character, and the damping action of the rollers 5, 6, 23, 24 and rewind reel 11. In a modification the ticker is disposed at an angle of about 45‹ to the path of movement of the tape across the light aperture in order that the tape may be turned or twisted over to present the printed face downwardly. The turning means comprises a bent wire secured to bracket mounted on the casing of the projecting apparatus, the effective portion of the wire being disposed in a horizontal plane preferably at an angle of 22#‹ to the path of movement of the tape across the light aperture. In this arrangement it is only necessary to provide a single mirror screen housing. The tape may be made of a washable stock, and may be re-used.

Title: Improvements in or relating to respiratory appliances
IPC: A62B9/02
Filed: 1938-02-01
Abstract: 514,366. Fluid-pressure servomotors. DRAGER, O. H. Feb. 1, 1938, No. 3099. Void. Convention date, Feb. 6, 1937. [Class 135] [Also in Group VI] In respiratory appliances, wherein continuous, and intermittent lung-operated, supplies of oxygen are provided, the lung-operated member is arranged to interrupt the continuous supply, the static pressure of which thereupon opens the valve of the intermittent supply. As shown the continuous supply, controlled by a valve 1, is led through a nozzle 2 and a passage 16 to a chamber 12 beneath a diaphragm 3, and thence through a passage 16a and an open valve 5 to the respiratory circuit at 14. The valve 5 is connected to a plate 8 on the breathing bag and is biassed open by a spring 15. On collapse of the bag, valve 5 is closed, and the pressure built up raises diaphragm 3 and opens the intermittent supply valve 4, connected to conduit 14 by a passage 16b. To avoid excessive pressure, which would oppose the re-opening of valve 5, a pressure relief valve 9 is provided which opens the continuous supply at a pressure slightly above that required to operate diaphragm 3, for example, 0.6 atmospheres. Instead of valve 9 a nozzle may be arranged and dimensioned to byepass valve 5 and to build up 0.6 atmospheres in passage 16a. The nozzle may be mounted in the valve 5. In a modified arrangement the diaphragm chamber 12 is normally byepassed but is opened to the pressure when the valve 5 is closed. Valve 4 may be opened manually on emergency by a knob 13 on an elastic diaphragm 19, or by a spring- held lever engageable with the stem 6 of valve 5 to close the valve. The valve stem 6 may have a terminal button detachably engaging a forked member on the plate 8, or may be secured to a diaphragm closing one end of the breathing bag and clamped between the bag fittings and the valve casing. The invention is applicable both to closed circuit and open breathing apparatus.
