Abstract: 1,267,663. Carbon fibre reinforced material. DEFENCE SECRETARY OF STATE FOR. 11 Aug., 1969 [13 June, 1968], No. 28121/68. Heading D1R. [Also in Division C3]  Carbon fibre reinforced thermoplastic resin composite material is produced by making a number of applications of a solution of a thermoplastic resin in an organic solvent to continuous or chopped strands of carbon fibres with substantial removal of the organic solvent after each application. The solvent is removed by evaporation aided by heating if necessary. The resins and/or the solvents used may be varied from treatment to treatment. If the strands are continuous they are preferably laid parallel to each other. The impregnated strands may be passed through rollers after each application and before removal of the solvent. The resulting pre-preg may be placed in a mould and subjected to heat and pressure to form a shaped article. A plurality of pre-pregs may be likewise treated with the parallel strands in each pre-preg parallel or aligned in different directions. The thermoplastic resin may be polystyrene nylon 66, polymethylmethacrylate, polycarbonate, vinyl chloride, vinyl acetate copolymers, polyvinyl chloride, cellulose acetate or a polysulphone.

Title: New polyvinyl hydroxymethyl ethers and a process for the production thereof
Inventor: GRAEFJE HEINZ
IPC: A61L2/20
Filed: 1961-08-03
Abstract: Polyvinyl hydroxymethyl ether, the corresponding polyvinyl alcohol of which has a K value between 20 and 90, and which has a degree of etherification of 5 to 100%, is prepared by reacting a solution or suspension of polyvinyl alcohol in an aqueous, organic or mixed aqueous-organic medium with formaldehyde at an elevated temperature at a pH of 6,5 to 9.  The polyvinyl alcohol may be partially esterified with fatty acid radicals, e.g. formyl, acetyl or propionyl radicals, or partially etherified with alkyl groups, e.g. methyl, ethyl or propyl groups.  Specified organic media are methanol, ethanol, butanol, dimethyl formamide, N-methyl pyrrolidone, dimethyl sulphoxide, dioxane and acetone.  The formaldehyde may be in the gaseous or dissolved state, or may be derived from a compound which yields formaldehyde, e.g. paraformaldehyde or trioxane.  The products swell and dissolve in water, and may be rendered water-insoluble by treatment with a mineral acid.  The products may be made into filaments and sheets, and, as they slowly release formaldehyde, are disinfectants.

Abstract: 998,864. Automatic exchange systems. SIEMENS & HALSKE A.G. July 24, 1962 [July 25, 1961; Nov. 16, 1961; April 3, 1962 (3)1, No. 28361/62. Heading H4K. Groups of subscribers, 2Tn. . . 5Tn, Fig. 3, are each provided with two multiplex highways such as SM2a, SM2b, one for each direction of traffic (i.e. direction in which the call is set up), the highways being arranged as rows of a coordinate system, column highways P1, P2 being connectible by switches to each of the rows so that pulsed connections may be effected between the incoming and outgoing highways of the various groups. Each group is provided with two circulating stores, one for containing calling subscribers' addresses and the other containing called subscribers' addresses, pulses from these stores operating on gates which connect the subscriber to highways SM2a or SM2b respectively. Gates connecting the columns to the rows are controlled from circulating stores such as Jl which store in the appropriate pulse position the addresser of the gates in the associated row. Further columns may be provided for connecting to incoming and outgoing junctions 1Lnb, ILna. These columns are split the upper half M la giving access to calling highways and the lower half M16 to called highways. In a modification, Fig. 3.1 (not shown), the columns serving the incoming and outgoing junctions intersect auxiliary intermediate row highways to enable tandem connections to be made. Alternatively, for tandem working, Fig. 3.2 (not shown), the multiplexer serving the incoming and outgoing junctions may be made to intersect with gates being provided at the intersection points. A combination of both of these methods may also be used, Fig. 3.3 (not shown). In an alternative arrangement, Fig. 5.1 (not shown), the incoming and outgoing highways may form rows, and column highways may be provided for connecting calling highways to highways serving outgoing and incoming junctions. Tandem connections may then be provided for by the use of further column highways intersecting the incoming and outgoing highways or by providing intersecting points between pairs of incoming and outgoing highways. In a further modification, Figs. 6.1, 7.1 (not shown), some pairs of calling and called highways (e.g. pairs serving the same group) may be provided with intersecting points whereby only one intermediate gate is required to be operated. In the case of bothway junctions each group has both an incoming and an outgoing highway in the same manner as a group of subscribers. The highways may be of the twowire variety or may consist of a pair of such highways for the go and return directions of speech, in which case at each intersection a pair of gates is required. Specification 981,336 is referred to.

Title: Method of refrigeration which combines two thermodynamic cycles and a cryogenic machine for carrying out said method
IPC: F02G1/044
Filed: 1974-06-26
Abstract: 1456420 Refrigerating COMMISSARIAT A L'ENERGIE ATOMIQUE 26 June 1974 [6 July 1973] 28385/74 Heading F4H A refrigeration system uses two distinct gas circulation systems in which the gases are subjected to two different thermo-dynamic cycles, each consisting of compression, cooling, expansion and reheating, the two systems being coupled so that at least one operation of each cycle initiates an operation of the other. In the apparatus described one cycle 140 is a Claude cycle using a uni-directional circulation of gas from a compressor and cooler 136 to the space C1 in which it is expanded by downward movement of piston 130. The other cycle 142 is a Stirling cycle and uses a reciprocating gas flow between spaces C<SP>1</SP> and C2, the piston 130 acting as a displacer causing the gas to flow through ducts 132 which contain heat accumulators 134. The piston is returned to its uppermost position by movement of a piston 128, compressing the gas in space C2. In operation the valve 124 opens when the piston 130 is at its top position to admit cold gas under high pressure. This pushes down the piston, the gas expanding and getting colder. The downward movement of the piston transfers gas from space C2 to spaces C<SP>1</SP>. The piston 130 is moved further downwards as piston 128 descends. Exhaust valve 126 then opens to allow the cold gas in space C1 to be expelled as the piston 130 rises again under the influence of rising piston 128. Cold may be extracted from the upper Claude system only or from the lower Stirling system only or from both. The purpose of combining the two systems is to balance the conditions of temperature and pressure in spaces C1 and C<SP>1</SP> so that difficulties of sealing and insulation are avoided. External ducts and heat accumulators may replace those within piston 130. The pressure of the gas in the lower space C2 can be varied by other means, e.g. by alternate connection to high and low pressure sources 150, 152. The Stirling machine may be replaced by a Taconis or Vuilleumier type or a pulse tube machine.

Abstract: 1,256,067. Rolling mills. ENGLISH ELECTRIC CO. Ltd. 6 Dec., 1968 [6 Dec., 1967; 14 June, 1968], Nos. 55457/67 and 28447/68. Heading B3M. [Also in Division G3] A workpiece is rolled from an initial thickness to a desired final thickness in a number of rolling steps, the roll gap and roll speed of each step being determined in a digital computer such that the overall throughput, or some other parameter of the mill, is maintained at an optimum value. The parameter may alternatively be the roll load, the roll speed, or the roll power in each step. The rolling steps may correspond to the stands 10-13 of a continuous mill, as shown, or may correspond to sequential passes in a single reversing stand. The computer 26, in addition to being fed with values of workpiece temperature and thickness, and rolling load, is fed with characteristics of the mill and the workpiece, and with an expression defining the desired parameter. By measuring the temperature of the workpiece as it enters the mill, and its thickness as it leaves, the predicted settings for the various rolling steps may be updated to compensate for any errors between actual and assumed values of the workpiece parameters.
