Abstract: 442,890. Delivering liquids by gas pressure. MORTENSEN, H. F., 2, Nedre Vollgate, Oslo, Norway. Aug. 17, 1934, No. 23790. [Class 102 (ii)] [See also Groups XXIX and XVII] A valve for spraying or dispensing devices comprises a slide cover moving over a valve seat to bring apertures therein into and out of register with one another, an apertured packing member consisting of a thin disc of cork being placed between the cover and valve seat and prevented from moving relatively to one of them by forming that one of the valve members with a roughened contacting surface. Fig. 1 shows a disc 2 with an aperture 11 movable over a valve seat having apertures 6 arranged equidistantly from a central pivot 3. The valve is held on its seat, with an interposed cork disc 8, by a resilient disc 1, The valve seat is roughened by grooving or by being provided with annular recesses or projections and the disc 2 is smooth. The part immediately surrounding the aperture 6 or a ring concentric with the pivot 3 on the valve seat may be left smooth. The pivot 3 passes through a block 4 having passages 5 leading to the apertures 6. The contacting surface may be flat, conical or spherical. A conical recess 10 may be provided in the disc 2 to take a spraying or other nozzle. The valve is particularly adapted for containers of aerated liquid or semi-solid substances, and when the discharge pressure is high the form shown in Figs. 4 and 5 may be used. A portion of a helical spring 1 is riveted to a projection 14 on a member 15 secured to the top of the container and presses a valve member 2 onto a packing disc 8, the aperture 6 being surrounded by a raised portion as shown to concentrate the seating pressure. The member 15 may have an extension 17 entering the container and connected to an extension pipe 18. The valve is movable by a handle 16 and the spring 1 may act to return the valve to its closed position. Alternatively a straight spring may be pivoted so as to have no restoring effect. A spraying nozzle of the kind described in Specification 351,214, [Group XXIX], is shown in position on the valve member. The valve member may have several openings of different sizes. Fig. 6 shows a valve member for a collapsable tube the member 2 being formed of spring steel with an extension 1 to hold it on the valve seat. In all cases the lower edge of the aperture 11 is rounded to prevent abrasion of the cork packing disc.

Title: Apparatus for transferring and recording picture and/or sound information
IPC: G03B27/50
Filed: 1975-06-03
Abstract: 1513393 Copying picture and/or sound information H PREUSS 3 June 1975 [6 June 1974] 23882/75 Heading G2A A succession of images on a film-strip 9 is transferred by projection into spiral formation on a disc 20, the disc and film strip being driven in unison by a single motor, and the copying operation being carried out by laser beam scanning or carrier frequency photography. As shown, the film-strip is conveyed by drive rollers 42 to and from the projector, passing through a gate formed by pressure plates 8. Light from a source 5 passes through a condenser system 6, through the film, a slotted diaphragm 10 and colour coding filter 7. The projection optics 13 reduce the size of the image falling on the disc 20 to the order of 1 sq. mm. Mounted on disc 20 is the actual film plate 17, over which is clamped a thin glass cover-plate 18. The disc 20 is rotatably mounted on a support 24 which can slide horizontally, and is urged to the left by a weight 26 attached to it by a rope 27. The rear surface of disc 20 carries a spiral groove, into which the teeth of a guide comb 30 engage, the comb 30 being fixed on a part of the support frame. Thus as disc 20 rotates, the engagement of the fixed comb teeth in the spiral groove causes the disc, with its support 24, to traverse horizontally, so that the image thrown on the disc by the projector system traces out a spiral path. Absolute synchronism of disc and film movement is ensured by deriving both drives from a single motor. The image-recording system may be covered by a lighttight screening hood 62 having an aperture 16 to allow the light to enter. Sound information may be similarly transferred and recorded, and instead of a light source a laser beam may be used. The system is used for the production of long-playing video records.

Filed: 1934-08-29
Abstract: 443,161. Cooling systems. ELLOR, J. E., Grandell, South Drive, Chain Lane, Mickleover, Derby. Aug. 29, 1934, No. 24854. [Class 29] In a cooling system for an internal-combustion engine in which vapour is generated, the hot vapour passes through a chamber f forming a wall between a condenser d<4> and its hotwell g, small passages g<1> being provided for the flow to the hotwell of the condensate, which is thus prevented from freezing in abnormally cold conditions. In the system shown in which a mixture of water and vapour is discharged from the cylinder jackets through nozzles c<1> into a header tank a, the. liquid is circulated through a radiator bl by a pump b<3>, and the vapour, collecting in a dome d, passes to the condenser d<4>, situated in an aircraft wing, through a pipe d<3> and holes f at the ends of the chamber f. The condensate flows from the hotwell g through a pipe h which passes inside the pipe d<3> and is thus heated. The condenser has perforated baffles j<2> and is vented by a pipe j opening at a point of positive pressure under the aircraft wing. The return of the condensate past a non-return valve i<2> is assisted by the ejector action of a Venturi i, through which liquid is forced by the pump b<3>. A valve in a casing d<2> closes the passage to the condenser when the aircraft is inverted.

Abstract: 1,010,505. Inductive signalling; echosounders. WESTLAND AIRCRAFT Ltd. Oct. 16, 1961 [July 16, 1960], No. 24867/60. Headings H4D and H4U. A communication system includes first and second spaced stations connected by a loop of ferromagnetic material, means at the first station for converting information signals into pulses of electrical energy and for utilizing said electrical energy to introduce a magnetic flux into the loop, and means at the second station for deriving electrical signals from changes in the magnetic flux in the loop. As described the system is used for passing information from an object in the water, e.g. a net connected to a ship by steel cables which form the magnetic loop. The information, which may be the depth of the object in the water is obtained by a known acoustic measuring device MG which produces an electrical quantity which is supplied to a trigger device T having two outputs. One output consists of a train of information pulses delayed with respect to a train of equally spaced reference pulses by an amount dependent on the instantaneous value of the electrical quantity supplied to T, the reference pulses providing the other output. The two outputs are supplied via a pulse amplifier P to separate coils in a transmission unit PU which are coupled to the loop L so that when a pulse is supplied to either coil a corresponding magnetic flux is detected by a unit D which may be a coil or alternatively a Hall generator. The output of the unit D consisting of pulse pairs is supplied via an amplifier A to a bi-stable circuit MI which converts each pulse pair into a single pulse of duration representative of the spacing between the pulses of the pair. The spacing between the duration modulated pulses is constant and after integrating the resulting voltage is applied to a voltage measuring device providing a direct reading of the quantity measured. The output of the amplifier A may also be applied to an oscilloscope C provided with a time-base TB. The transmitter unit PU consists of a gapped core G1, G2, Fig. 2, provided with holes H1, H2 so that the unit may be connected into the loop L by shackles. The gapped core is surrounded by two coils L1, L2 provided with terminals L3, L4 and L5, L6 respectively and the unit is provided with a waterproof cover B. The gapped core may be provided with a link of diamagnetic material to take the load applied to the loop L. A detector unit D consists of a ferromagnetic rod drilled at each end to receive a shackle and surrounded by a single coil. The pulse amplifier P consists of a pair of thyratrons, Fig. 4 (not shown) which are triggered alternately by the respective pulse trains from the trigger device T.
