Title: Improvement in colloidising cellulose esters and the manufacture therefrom of highlyflexible sheeting
IPC: C08J3/09
Filed: 1933-07-08
Abstract: Highly flexible sheetings are prepared by colloidizing cellulose acetate propionate having a propionyl content of at least 10 per cent and in which at least \ba1/2\be per cent and not more than 6 per cent of the combined acyl content of the ester has been hydrolyzed off or replaced by hydroxyl groups with a solvent consisting of a major proportion of propylene chloride and a minor proportion of methyl alcohol and depositing the resultant solution on a film-forming surface.  The solvent mixture may contain the methyl alcohol component in a proportion of 10 to 30 per cent.  A slightly hydrolyzed cellulose acetate propionate prepared as described in Specification 398,626 and containing 15 per cent propionyl and 26 per cent acetyl may be employed.  A plasticizer such as triphenyl phosphate may be present, and in this case it is preferable to strip the films from the forming surfaces before they are completely cured, since in this case the products are of greater flexibility.  The proportion of solvent to ester employed may be 5 : 1 or 6 : 1 by weight.  Examples are given.  Solutions of slightly hydrolyzed cellulose acetate propionate in the solvents specified may also be employed by known methods for artificial silk manufacture, lacquering and overcoating in general, artificial leather &c.  Known plasticizers, cellulose esters, resins or other comparable plastic materials may be added if desired in the application of these solutions.  The Specification as open to inspection under Sect. 91 comprises also the use of ethyl, normal propyl, isopropyl, normal butyl, isobutyl, tertiary butyl or other lower aliphatic alcohol in place of methyl alcohol.

Title: Telephone subscribers metering system
IPC: G06F11/16
Filed: 1972-04-27
Abstract: 1348605 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 27 April 1972 [29 April 1971 (4); 22 May 1971] 19626/72 Heading H4K In a telephone metering arrangement utilizing a line scanner, a ferrite core memory and a wired program processor, these units are all duplicated and both memories are updated simultaneously irrespective of which scanner and processor happens to be active whether under normal working or as a result of a fault. Each memory contains 2048 words of 18 bits for serving the metering requirements of 3000 subs. In each word one bit is used for parity purposes and one bit is spare. A memory is divided into 3 zones, a first of which contains 256 words for storing at each bit position the current status, i.e. metering pulse present or absent, of a particular subscriber; a second of which contains 1536 words for storing over eight bits the cumulative totals (up to 256 units) for each subscriber; and a third of which is used for buffering the totals in the second zone prior to transfer into a tape perforator, printer, magnetic tape or digital cassette type accumulator. In the third zone half the words are used for receiving totals (actually the addresses of the totals, i.e. the line identifiers) from the second zone as and when they occur while the other half of the words are used in the buffering process to the slow but steady speed accumulators. When the first half is full the accumulators read these out while the other half are then used for receiving the totals and so on. The totals are notified to the third zone when the 8-bit counters of the second zone count down to zero in response to decrementing bits from the first zone. Regular testing of the processors for accurate incrementing of the memory in response to metering pulses is effected using simulated subscribers' test points. Fault alarms (visual and audible) are provided on a maintenance console which can also access any desired memory compartment so as to alter or delete (e.g. ceased subscriber) its contents. The equipment is provided on printed circuit boards, any one of which can be identified by fault detection procedures. The arrangement may be used instead of or in conjunction with subscribers' mechanical meters.

Abstract: 1,146,379. Bis - phosphite esters. MELLEBEZONS. 28 April, 1967 [5 May, 1966], No. 19767/67. Heading C2C. [Also in Divisions C3 and C5] The invention comprises organic phosphites of the formula in which R 1 , R 2 , R 3  and R 4  which may be the same or different are alkyl, cycloalkyl, 4<SP>1 </SP>- hydroxycyclohexyl - 4<SP>1</SP> - isopropylidenecyclohexyl, aryl, or alkylaryl radicals. They may be obtained by transesterification between one mole of isopropylidene-bis-(4-hydroxycyclohexyl) and two mols. of triphenyl phosphite so as to form isopropylidene-bis-(4- diphenylphosphite - cyclohexyl) and then if necessary affecting transesterification between one mol. of the latter and from 1 to 4 moles of one or more alkanols, 2,2-dicyclohexanol-propane, cycloalkanols or alkylphenols to replace one or more of the phenyl groups by the desired substituent. Preferred reactants in the second stage are n-butanol, decanol (e.g. as obtained by OXO synthesis), octylphenol, nonylphenol, and dimethylcyclohexanol. The transesterification steps are preferably carried out in the presence of an ionizing catalyst, e.g. an alkali metal or alkaline earth metal hydroxide, carbonate, alcoholate or phenate, a strong mineral acid or a polyvalent metal salt. When triphenyl phosphite is reacted with an equimolar proportion of isopropylidene-bis-(4-hydroxycyclohexyl) in the presence of soda the phosphite of the formula is obtained. On further transesterification a product having a polymeric structure of the type wherein the index n is of indetermined value may be formed and the invention also includes such monomeric and polymeric phosphites as novel products. The products are useful as stabilizers and antioxidants for plastics materials and for lubricants and hydraulic transmission fluids.
