Abstract: 1,086,321. Testing tension in cables. WHITE FISH AUTHORITY. Oct. 9, 1964 [July 10, 1963], No. 27423/63. Heading G1W. An instrument for measuring the tension in a cable 58 comprises a pair of spaced components 11 adapted to contact one side of the cable, an intermediate component 55 adapted to contact the opposite side of the cable and adjustable to vary the gap between the components so as to provide a zero setting for the particular cable, a tensioning device to cause bowing of the cable over the intermediate component, and a strain gauge responsive to straightening loads applied to the length of cable bowed between the spaced components. In use, a wheel 55 is first moved to its limit downwards by turning an upper tube 18 and the wheel is then removed. The towing warp or cable 58 to be tested is introduced within a yoke 51 to engage the wheels 11, and the wheel 55 is replaced. The upper tube 18 is then turned until the wheel 55 contacts the cable. A handle 28 is turned through 180‹ from the position shown in Fig. 1 and an eccentric wheel 26 causes the inner shank 13 Fig. 2 (not shown) to be raised along with the tube 12 (not shown), the yoke 51 and the wheel 55 thus bowing the cable. The tension in the cable tends to straighten it out causing a tensional strain in a link 44 (not shown) which incorporates a metal foil strain gauge.

Abstract: 1284519 Spray producers T IKETANI 11 June 1971 [18 Dec 1970] 27533/71 Headings FIR R3A3D2 and R3A3D12C In a sprayer, in which the cyclic ambient heating and cooling of a bi-metallic disc 1 is used to produce intermittent operation, a lid 4 has adjustable apertures to vary the amount of ventilation of chamber 2 and dew, collecting on the exterior of housing 3, is conducted into the neighbourhood of spray nozzle 10 so as to be blown off into the atmosphere. The spray liquid contains a propellant gas and a volatile liquid such as methanol, acetone or ether. The liquid passes up duct 19 from a pressurized container and through a flow-control valve 12, co-operating with seat 16. On warming the disc 1 up to ambient temperature, the valve-member 12 is lowered, to allow the liquid to pass up to nozzle 10 and through duct 11 to synthetic on natural sponge 5, supporting the disc 1. The propellant gas evaporates immediately in chamber 2 and cools the disc 1 to close the valve 12. The rate of evaporation of the volatile liquid is controlled by the amount of ventilation of chamber 2. The greater the ventilation, the longer it takes the disc 1 to be re-heated to ambient temperature to recommence spraying. For manual operation, lid 4 may be depressed so that stem 20 opens valve 12.

Title: An improved degreasing plant
IPC: C23G5/04
Filed: 1930-09-16
Abstract: An apparatus for degreasing metal articles with solvent vapour consists of an open tank in which a movable work carrier is supported having cooling coils or other condensing means mounted thereon.  The cooling coils may be combined with the upper or lower parts of the carrier, or both, and a separate coil may be mounted in the tank independent of the carrier.  A suitable apparatus consists of still b containing trichlorethylene or other volatile solvent connected by a pipe c through which the vapour passes to a tank k, condensed solvent returning through a pipe d. A work carrier, consisting of two perforated plates f, g and a screen h connected together by a hollow stem i, is suspended in the tank by a chain m passing through the stem i, the carrier having rollers k running on guides j.  Cooling coils p, q are mounted above and below the plates g, f.  Water is admitted to the coils through a valve r and flexible pipe S and returns through a pipe t.  The valve r is operated by a bifurcated lever v coacting with a fixed abutment w, so that on raising the carrier, water flows through both <PICT:0360568/III/1> coils p, q, and in the lowered position, water flows through the upper coil p only.  In operation, the tank is filled with solvent vapour, and the carrier is raised and loaded, egress of solvent being prevented by the lower cooling coil.  The carrier is then lowered, and tank is thereby closed by the screen h.  The solvent vapour is condensed by the upper cooling coil and falls in a shower on the articles.  When degreasing is complete, the work carrier is raised and the cleaned articles are removed.

Title: Improvements in the preparation of polypropylene films
IPC: B29C55/18
Filed: 1960-08-10
Abstract: A coated film is made by applying a combination of a butadiene-acrylonitrile copolymer and a prepolymer of resorcinol and formaldehyde diluted with methyl ethyl ketone to a polypropylene film which has been chlorinated in sunlight for three days at room temperature.  The polypropylene film is made by heating polypropylene to form a clear melt, forming the melt into a sheet 2-10 times the thickness of the final film, passing the sheet between pressure rollers at from 180  DEG F. to the fatigue temperature of the polypropylene to reduce the thickness to the desired value, and heat-setting the film under sufficient tension to prevent any elastic recovery at from 18  DEG F. less than the creep temperature to the fatigue temperature.  An aqueous alcoholic gelatin solution may then be applied to the resin layer and after drying, a gelatin-silver halide emulsion may be applied and dried. Such a coated film may be used for photographic purposes (see Division G2).
