Title: A Safety Apparatus for Launching Ships' Boats.
Inventor: IMRAY OLIVER
IPC: B63B23/04
Filed: 1917-12-08
Abstract: 120,289. Imray, O., (Montreal Patents Promoting Co.). Dec. 8, 1917. Constant-tension and tensionregulating winding and paying- out apparatus.-A boat-lowering gear actuated by fluid pressure is provided with reversing valves controlled by variations in the tension of the lowering cables, to keep the cables taut and the boat on an even keel. The boat is lowered bv four cables 63 each of which passes over a swivelling pulley at the davit head, through a davit, around deck pulleys, around a pulley 58 mounted on a carriage sliding in a frame 54, around a pulley 59 mounted on a shaft turning in fixed bearings, around pulleys 43 mounted on a shaft turning in fixed bearings, around pulleys 48 mounted on a carriage 46 adapted to be moved along a guide-way 47 by a hydraulic cylinder 52, and is finally secured to a pulley 42 as a shaft 40 mounted in fixed bearings. The pressure supply for operating the cylinders 17<a>, 52 which is controlled by a pair of slide valves operated by handlevers is obtained from a reservoir into which oil is pumped by a multi-throw pump. In order to take up any slack in the lowering cables and at the same time wind in the taut cables to keep the boat on an even keel while it is riding on the water, four automaticallyactuated valves are provided for alternately connecting the cylinder 52 to pressure or exhaust. These valves 135, 127 are connected in pairs through screw and linkage mechanisms to the carriage 55 so that as the spring moves the carriage when the cable slackens, the valves 135 are closed to shut the exhaust passage and the valves 127 are opened to admit pressure fluid. The valves are fitted with electro-magnets to make them quicker in action, and a pair of interconnected cam-actuated valves are provided to throw the automatic valves out of action.

Title: An improved composition for preparing films for use as substitutes for gold beaters skin and the like
IPC: D06M15/07
Filed: 1916-12-20
Abstract: Gas-stopping linings in the form of films are attached to the fabrics used in aircraft, for example, to the ballonets of airships.  The films are formed by applying a solution such as nitrocellulose and rubber dissolved in amylacetate and naphtha to which castor oil may be added, to a smooth surface by pouring, dipping, painting, or spraying, and are stripped by immersion in water heated to 60-100 DEG C.  The film may be formed by spraying on to a moving band of steel,, which passes between steam-heated rollers to dry the film, and then to a stripping-bath of hot water.  Bands or tapes may be attached to the sides of the film for temporary support.  Composite films may be formed by pressing two or more films together, or by attaching them by an adhesive solution consisting of rubber, naphtha, and amyl acetate.  A composite film may also be formed of an outer film formed of nitrocellulose butyl acetate and naphtha, to which castor oil may be added, a central layer of low permeability to hydrogen and formed of glycerine and glue, and an inner film formed of nitrocellulose and containing rubber, so that the film may be attached, by an adhesive solution which contains solvents for nitrocellulose and rubber, to a rubber-proofed fabric.  A suitable adhesive solution consists of nitrocellulose, rubber, butyl acetate, and naphtha.  The films may be submitted to cold vulcanizing such as is employed in the treatment of india-rubber.

Title: Ultrasonic transmitter and/or receiver
IPC: G01S7/521
Filed: 1974-04-29
Abstract: 1508305 Ultrasonic transmitters and receivers SUNDERLAND POLYTECHNIC 28 April 1975 [29 April 1974] 18662/74 Heading H4J A directional ultrasonic sound transmitter and/ or receiving device comprises at least one reed I (Fig. 1) with at least one transducer 3 (e.g. a piezoelectric element) secured to it. The reed 1 is clamped in a mounting block 2. Ultrasonic waves are launched from or received by the free end of the reed I when the wave speed of bending waves in the reed is identical with the speed of sound in the ambient medium. In addition the thickness of the reed 1 is such that the wavelength of the bending waves in the reed is the same as the wavelength of the ultrasonic waves launched into the ambient medium and the length of the reed is an integral multiple of half such wavelength. The length is preferably from 5 to 20 wavelengths. The effective length of the reed may be increased by using a reflector 4 extending for at least one wavelength in all directions perpendicular to the axis of the reed. The length of the reed 1 in front of the reflector 4 is effectively doubled due to a mirror image effect. The width of the reed is large compared with the thickness and wavelength to reduce any tendency to develop cross vibrations. The response pattern has a major lobe in the direction of the reed. Side lobes may be reduced by placing a sound absorber near one face. A piezoelectric element 3 is preferably received on each side of the reed. A two reed version (Fig. 2) has two reeds 1a, 1b each with two piezoelectric elements 3. The reeds are driven in antiphase and emit sound in the direction 6. One blade may act as a transmitter and the other as a receiver which picks up reflections emitted by the transmitter blade. Applications include an aid for the blind and a security device for detecting intruders. The electrical signals derived from vibrations of the receiving blade are amplified and give some audible indication of distance or actuate a warning device. Electric circuitry powered by a battery may be within a holder 2.
