IPC: B29C48/05
Abstract: 1,143,583. Synthetic resin compositions. KONINKLIJKE NEDERLANDSCHE MACHINEFABRIEK V/H E. H. BEGEMANN. 8 March, 1966 [9 March, 1965], No. 10166/66. Headings C3B, C3P and C3R. [Also in Division B1] A composition comprising a thermosetting resin, e.g. an epoxy resin, a phenolic resin or an unsaturated polyester (100 parts by weight), from 25-35 parts by weight of a reinforcing fibrous material having length of 3-8 mm. and from 50-150 parts by weight of a non- fibrous filler (e.g. quartz of particle size 30Á) is subjected to a repeated kneading operation in which parts of the mixture are removed from the kneading zone and returned later. In this way at least 80% of the fibres which are initially present in bundles become separated into individual fibres. The temperature in the kneader is kept below the polymerization temperature of the resin. Examples of typical compositions are (1) polyester resin (100 parts by weight), glass fibres (30 parts), asbestos powder of max. particle size of 50Á, quartz powder of max. particle size 30Á; (2) 100 parts by weight of epoxy resin, 35 parts by weight of glass fibres and 50 parts by weight of asbestos powder (50Á). The diameter to length ratio of the fibres may be in the range 1: 200 to 1: 500. The fibres should be completely enclosed by polymerized resin, i.e. the length of the fibres should be at least as small as the minimum cross-sectional dimension of the article.

Abstract: 1,225,668. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 7 June, 1968 [30 June, 1967], No. 27313/68. Heading H1K. A semi-conductor array comprises a flexible base sheet 12 of non-conductive plastics material on to one surface of which are bonded a plurality of metal strip conductors 18 and a plurality of semi-conductor chips 14, each chip having a plurality of metal contacts formed on one surface, electrical interconnections being made between the chip contacts and selected strip conductors. A further flexible sheet 16 of non-conductive plastics material having a plurality of metal strip conductors 20 bonded to one surface may be laid on the first sheet so that the two sets of conductors on the sheets cross one another and interconnections may be made as required. The semi-conductor chips 14 are positioned between the strip conductors and connect to them by means of fine jumper wires. The conductors may be of aluminium or gold, connections being made by thermo-compression bonding. Tab portions 16b extend beyond the edges of the flexible sheets 16 to allow connection to external circuits, and the whole array may be folded so that these tabs are brought into close proximity to allow short interconnections to be made between selected tabs. The array may be immersed in a non- conducting cooling fluid, and insulating sheets may be placed between the folds. The metal strip conductors can be converted to transmission lines if required by providing a metallized backing to the plastics sheets. In a further embodiment, thermocompression bonding is used to connect the metal strip conductors directly on to the electrodes of the semiconductor chips to dispense with the jumper wires. In this case the chips are disposed between the flexible plastics sheets which are disposed with their conductor bearing faces towards each other, the conductors being tailored as required, Fig. 17, not shown. Where interconnection between the strip conductors is required, thermocompression bonding is employed as before.

Abstract: 1,230,952. Polyamide - acids; polybenzoxazinone-amides. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 28 Feb., 1969 [28 Feb., 1968], No. 10961/69. Headings C3C and C3R. Polyamide-acids comprise a chain of recurring units (I) in which Ar is a trivalent radical comprising # 1 aromatic ring; R is a divalent radical comprising # aromatic or heterocyclic ring which may be substituted with alkoxy, alkyl, or halogen; if Ar or R contain >1 ring, these are condensed or linked by a direct bond or by -O-, -S-, -SO-, -SO 2 -, -CO-, CH 2 -, CMe 2 -, -SiMe 2 - or CONH-; R<SP>1</SP> is H or monovalent hydrocarbon radical; the polyamide-acids have inherent viscosity #0À1 dl/g. (30‹ C.) for 0.5% solution in N-dimethylacetamide. The polyamide-acids may be formed by reacting at least one compound (III) with one or more compounds (IV) where Y reacts with the amino groups of (III) to form a carbonamide group, Ymay be -OR<SP>11</SP>, where R<SP>11</SP> = H- or monovalent aliphatic or aromatic hydrocarbon radical preferably containing 1-20 C atoms; or Y may be -NH 2  or halogen. The reaction temperature may be -30‹ to 220‹ C. The reactions are preferably performed with equimolar proportions of (III) and (IV), though up to 50% excess of either may be used. Reaction media are preferably polar solvents e.g. N,N - dialkyl - carbonoxamides, dimethyl sulphoxide, dimethyl sulphone, or N - methylpyrrolidone, or mixtures thereof with each other or with C 6 H 6  or C 6 H 5 CH 3 . Alkali or alkaline-earth metal salts e.g. halides, may be added to increase the solubility of the polymer. Polyphosphoric acid may be used as reaction medium. If Y in (IV) is a halogen, tertiary amines may be added to act as acid acceptor. Interfacial polycondensation may also be used to form the polyamide-acids from a waterimmiscible solution of (IV) and aqueous (III). The polyamide-acids may be isolated by precipitation in a large excess of salts; the polymers are then crushed, washed, and dried to white powders soluble in polar solvents. Uses: Solutions of polyamide-acids may be used to form films or fibres; or they may be used to form expanded polybenzoxazinone-amides e.g. by gas-release during cyclization, e.g. using formic acid. Polybenzoxazinone - amides having recurring units (II) may be obtained by reacting (II) and (IV) at -30‹ to 400‹ C.; a polymer having solubility lower than 0.5 wt. per cent in dimethylacetamide at 30‹ C. may be obtained thus. Alternatively, the polyamide-acid may first be formed as above and then converted to polybenzoxazinoneamide by heating at 200-400‹ C. or by reacting the polyamide-acid at -30‹ to 100‹ C. with an aliphatic or aromatic acid anhydride, in the presence of a tertiary amine under reduced pressure.

Abstract: 1290379 Arresting aircraft BORGS FABRIKS AB 12 Dec 1969 [19 Dec 1968] 60855/69 Heading B7G [Also in Division B8]  Apparatus for use in the arresting of aircraft comprises a cable 2 stored in a peripheral groove 3 of a magazine 1, a carriage 5 whose wheels 6 run freely on a track 4, and cable guide means 7 associated with the carriage. The cable 2 is attached to an arrestor cable stretched across a runway, and is stretched tangentially across a bollard 8 consisting of one or more rotatable grooved cylinders or stacks of wheels (Figs. 4, 5, not shown) surrounded by helical cable guides (18). Movement of the cable caused by arrest of an aircraft causes it to pass across the bollard and to unwind from the magazine as the carriage is moved round the track. The carriage is provided with a brake 9 (Fig. 3, not shown) and the large diameter of the track provides a large heat sink. Acceleration (and hence stresses) may be reduced by the addition of jockey pulleys 24, 25 (Fig. 7), each being automatically displaced from the rotation plane of the cable as soon as the cable has left it. An alternative arrangement employs an initial radial track 27 (Fig. 8, not shown) connected to track 4 by a movable section (26) thereof. An aircraft may be arrested on a different level or deck to that on which the above apparatus is situated (Fig. 6, not shown).  Also, a sliding cradle may be used instead of a wheeled carriage. Rewinding of the cable is achieved by means of element 29 (Fig. 1), in the form of a chain with fingers 30 which engage the carriage and move it in the direction opposite to that in which it travels during arrest. The bollard may also rotate.

Abstract: 1296986 Jet propulsion plant; fluid logic and switching circuits DEFENCE SECRETARY OF STATE FOR 19 March 1970 [27 March 1969] 16164/69 Headings F1J and F1P A gas turbine jet propulsion engine fuel system. comprises a closed loop fluidic system including proportional amplifier means the output of which is connected to control the fuel pump delivery, and the effective input of which is a function of the difference between jet pipe pressure and a variable reference pressure, the latter including as components at least one compressor pressure and a feedback controlled by the output of the proportional amplifier means. The fuel pump 10, which supplies fuel via a throttle valve 14 to a re-heat manifold, is driven by an air turbine 11 fed via a throttle valve 21 with air at a high-pressure compressor delivery pressure P 3 . When re-heat is desired, a shut-off cock 24 is opened by means of a pilot's switch S 1 , a further switch S 2  operable by an engine speed signal preferably being provided. This energizes the air turbine 11 and also, via respective lines 64 and 82, two monostable fluidic amplifiers 60,80. The output then provided by the amplifier 80 at a line 83 passes to rams which move the propulsion nozzles from the closed condition to a pre-opened condition. The air throttle valve 21 is actuated by a piston 45 controlled by two series-connected proportional fluidic amplifiers 31, 32 energized by air at the pressure P 3 . One control port of the amplifier 31 is subjected to the jet pipe pressure P 6  while the other control port is subjected to a reference pressure P x  derived from a pressure splitter 40 fed via respective restrictors 43,42 with the pressure P 3  and a lower compressor delivery pressure P 2  and also connected to the atmospheric pressure P 0  via an adjustable valve 41 and also via a valve controlled by a needle 44 which provides position feedback for the piston 45. The monostable amplifier 60 has its normal or stable output fed via a line 70 to the amplifier 31 to override the P 6  input signal whereby the throttle valve 21 is shut until the re-heat combustion equipment is fully lit up. When light-up has occurred, the resultant increase in the pressure P 6  compared with a reference pressure P x , derived in a pressure splitter 65 from the pressures P 0 , P 2 , P 3  switches the output of the monostable amplifier 60 from the line 70 to a line 75, and the pressure P 6  then assumes control of the air throttle 21 through the proportional amplifiers 31, 32. The output pressure in the line 75 is applied via a line 76 to latch the monostable amplifier 60 into its unstable state and also acts on the monostable amplifier 80 to switch its output from the line 83 to a line 84 to bring the propulsion nozzles from the pre-open to the fully open condition. When neither of the lines 83,84 have an output, i.e., when the shut-off cock 24 is closed to terminate the reheat, the absence of inputs from either of the lines 83, 84 to an "OR" device 90 produces an output in a line 96 to close the propulsion nozzles.
