Title: Improvements in or relating to liquid level indicators
IPC: G01F23/72
Filed: 1957-07-16
Abstract: 811,417. Liquid level indicators. GENERAL ELECTRIC CO. Ltd., and MATTHEWS, A. July 16, 1957, No. 22523/57. Class 40 (1). A liquid-level indicator comprises at least one inductance coil contained within a non-magnetic tube which is at least partly disposed inside a container for the liquid and a magnetic member disposed outside the tube and rigidly secured to a float disposed inside the container and surrounding the tube so as to be guided for movement along the length of the tube. The arrangement is such that variation in the level of the liquid causes movement of the float and the magnetic member, thus varying the selfinductance of at least one coil and/or the mutual inductance between a pair of coils. As shown, the magnetic member comprises an iron tube 14 surrounding the non-magnetic tube 6 containing two inductance coils 8, 9 electrically connected in series. The tube 6 which is conveniently made of an alloy of nickel, chromium and iron is provided at each end with rubber stoppers and is welded at its upper end to an aperture in the cover 2 of the container 1. The float 15 is arranged to be relatively shallow so as to minimize errors due to changes in the density of the liquid. The leads 10, 11 and 12 are connected in an electrical circuit such as that described in Specification 759,041 to obtain an indication of the level of the liquid in the drum 1.

Abstract: 1,056,841. Packaging - machines; endless conveyers. K. KORBER. July 25, 1963 [June 13, 1962], No. 22681/62. Headings B8A and B8C. A machine for filling open-fronted containers with stacks of cigarettes or other rod-like articles is characterized in that the containers are fed to the filling device in the direction of the longitudinal axis of the cigarettes, are moved in this direction to the starting position for filling, and after filling are moved in the same direction from the filling device. Feed of containers.-In one embodiment, Fig. 3, the empty containers 230, are suspended by hooked members 242 from carriers 241 on a truck 240, and are carried to the filling device 250, where they are supported during filling by guides 251, 252, and lowered step by step by these guides as each layer of cigarettes is inserted. After filling the containers are replaced on the truck in grooves 243. Any number of trucks may be coupled together to form a reserve supply of empty containers. In a second embodiment (Fig. 4, not shown), empty and filled containers are supported in random order from hangers on an endless conveyer and are fed to a pick-up device which allows unhindered passage of filled containers, but releases empty ones from their hangers and lowers them on to a platform from which they proceed to a filling device as before. After filling, the containers are raised by a lifting device and enter a free hanger on the conveyer. Feed of cigarettes by conveyer.-The cigarettes C are supplied by a chain 11 having grooved links 11a Fig. 5, joined by flexible members, e.g. coil springs 12 or extensible rubber. The chain is driven by sprockets 13-15, Fig. 2, whose speed is so adjusted that the spacing of the links away from the filling device corresponds to the input from a feed conveyer, and the links are closed up at the filling device to form a complete layer of closely-packed cigarettes which is then transferred whilst the end of the conveyer is stationary, to a container by a plunger or blower device. Instead of the flexible conveyer cigarettes may be carried on two pairs of parallel worms, the first pair corresponding in pitch to the feed conveyer and the second pair to closely-packed cigarettes. Alternatively, a single pair of worms of progressive pitch may be employed. Replacement of faulty or absent cigarettes.- As the cigarettes C pass along the conveyer 11 they are checked by a device (not detailed) which removes faulty cigarettes and simultaneously sends a signal to the operating device of a rotary refilling drum so that it feeds a satisfactory cigarette from a magazine to replace the rejected one. The refilling drum which may be controlled mechanically or by photo-electric means also fills any links left empty.

Title: Improvements in or relating to formaldehyde polymers
IPC: C08G2/00
Filed: 1953-08-28
Abstract: Solid formaldehyde polymers having an inherent viscosity of at least 1.0 measured as a 0.5 per cent solution at 60 DEG  C. in p-chlorophenol containing 2 per cent alphapinene and a "degree of toughness" at least 1 are made by continuously passing, e.g. dropwise, substantially anhydrous monomeric formaldehyde into an inert liquid reaction medium and allowing the formaldehyde to polymerize continuously as it introduced.  The polymerization may be effected at temperatures from -50 DEG  to +170 DEG C., in the presence of a dispersing agent and a polymerization catalyst. "Degree of toughness" is the number of creasing cycles which a film will withstand before breaking, the creasing cycle consisting of folding a film through 180 degrees and creasing, then folding in the reverse direction through 360 degrees and creasing again, the test film being one which has been maintained at 105 DEG  C. for seven days.  The formaldehyde may be obtained from the pyrolysis of alpha-polyoxymethylene.  Liquid media exemplified are decahydronaphthalene, benzene, cyclohexane, pentane, carbon tetrachloride.  Other media mentioned are propane, butane, hexane, heptane, octane, decane, cyclopentane, methylcyclohexane, 1,4-dimethylcyclohexanes, toluene, xylene, nitriles, acetals and ethers.  The dispersing agent may be the reaction product of ethylene glycol with wool wax alcohols, the long chain fatty di-esters of polyethylene glycols and polypropylene glycols, e.g. the di-oleic acid ester of polyethylene glycol, glycols of molecular weight above 200, silicone oils, alkylarylpolyoxymethylene glycol ethers, the reaction product of rosin and olefin oxides, sodium oleate, lead stearate, or sodium caprylate.  Catalysts mentioned are methyl, ethyl, butyl, octyl, dodecyl, octadecyl, dibutyl, ethyloctyl, tributyl, trihexyl, dimethyloctadecyl and didodecylmethylamine, aniline, toluidine, triphenylphosphine, tritolylphosphine, trixylylphosphine, trinaphthylarsine, tributylphosphine, triethylstibine, methyldioctylarsine, hydrazine and substituted hydrazines, morpholines and substituted morpholines, piperidines, N-alkylpiperidines, N,N-diethylaminoethanol and mixtures.  The dispersions may include a stabilizer such as alpha-pinene and also an antioxidant.  The polymers may be mixed with pigments, fillers, plasticizers and stabilizers and made into sheets, films, fibres, filaments and bristles.
