Title: Improvements in the manufacture of micro-porous material
IPC: H01M50/414
Filed: 1953-07-15
Abstract: Microporous material is obtained by subjecting a sheet, which comprises a thermoplastic material such as a rubber or a polyvinyl resin, fine particles which may subsequently be removed, and a solvent which wholly or partially dissolves the thermoplastic material while having no deleterious effect on the fine particles. after the solvent has been wholly or in part removed, to mechanical work whereby the sheet is reduced in thickness or increased in another dimension so that adjacent particles are forced into intimate contact and their encapsulating membranes disrupted, the fine particles being then removed. In examples, a mixture is made from either polyvinyl chloride or a copolymer of vinyl chloride with vinylidene chloride or a butadiene-acrylonitrile copolymer, sodium chloride, methyl cyclohexanone and either dibutyl phthalate or polypropylene silicate and is sheeted to approximately 0.08 inch and then calendered to 0.02 inch, the solvent is then removed in an air oven and then the sheet calendered to 0.012 inch, and after leaching out the salt the microporous sheet is dried. Isophorone may also be used as the solvent. Specification 565,022 is referred to.ALSO:Microporous material is obtained by subjecting a material in sheet form which comprises a thermoplastic material such as rubber, fine particles which may subsequently be removed, and a solvent which wholly or partially dissolves the thermoplastic material while having no deleterious effect on the fine particles, after the solvent has been wholly or in part removed, to mechanical work whereby the sheet is reduced in thickness or increased in another dimension so that adjacent particles are forced into intimate contact and their encapsulating membranes disrupted, the fine particles being then removed.

Title: Fault locating installation - designed for four line transmission systems esp. carrier frequency or PCM line ccts.
IPC: H04B17/40
Filed: 1973-01-11
Abstract: The installation tests from a remote position a number of amplifier sections connected one after the other. The intermediate amplifiers are remotely fed by a constant D.C. from a final position.

This closes loops in the intermediate amplifier stations for both the power supply and signal transmission circuits. These circuit completing loops are disconnected in sequence as testing of the functions of the station are completed, and the location of a fault is ascertained. The test switching is under control of the power supply from the end station.

Title: Production of anthraquinone from naphthalene
IPC: C07C50/18
Filed: 1973-04-13
Abstract: In the production of anthraquinone wherein naphthalene is oxidized to form naphthoquinone and phthalic anhydride, the naphthoquinone is reacted with butadiene to form tetrahydroanthraquinone, and the tetrahydroanthraquinone is reacted with oxygen to form anthraquinone, the improvement which comprises effecting the reaction of naphthoquinone with butadiene at an elevated temperature in the presence of naphthalene to produce a reaction mixture comprising naphthalene, tetrahydroanthraquinone and phthalic anhydride, separating the naphthalene from said reaction mixture, reacting the remaining mixture comprising tetrahydroanthraquinone and phthalic anhydride at an elevated temperature with molecular oxygen, and removing phthalic anhydride from the oxidation reaction mixture comprising anthraquinone and phthalic anhydride. Because the solvents in the several steps are naphthalene and phthalic anhydride and these are part of the system anyhow, obviously there is no contamination with extraneous materials. The equipment is simple and inexpensive and produces the desired material in high yield and purity.
