Abstract: 1419046 Screw-and-nut mechanism FRIEDRICH DECKEL AG 7 March 1974 [7 March 1973] 10375/74 Addition to 1191375 Heading F2Q In a mechanism comprising a screw 1 and ball nut 2 adapted to move a member 7 towards or away from the nut 2 on rotation of the screw 1, a drive wheel 15 is mounted on an extension 14 of the screw 1 and is coupled thereto by a coupling incorporating complementary interengaging surfaces 22, 23 so that when the wheel 15 is driven in either direction an axial thrust component actuates a friction brake 16, 17 for braking rotation of the shaft 1. This braking force must be overcome in addition to the resistance of the load in order to effect movement of the member 7. The coupling comprises a bush 26 secured to the extension 14 by a screw 24 and a key 25. The member 7 is secured to the screw 1 by a flange 5, located between a shoulder 9 and a nut 11 by thrust bearings 3, 4. In a modification, a multiple disc brake replaces the friction brake 16, 17.

Abstract: 1406378 Carbon films or fibres SUMITOMO CHEMICAL CO Ltd 5 March 1973 [6 March 1972] 10555/73 Heading C1A Carbon film or carbon fibre is produced by subjecting polyindene, polyacenaphthene, or a polymer having the unit formula wherein R 1  is an aromatic hydrocarbon group or a heterocyclic aryl group and R 2  is a hydrogen atom, an alkyl group, an aromatic hydrocarbon group or a heterocyclic aryl group to an aromatic substitution reaction which may be sulphonation, chlorosulphonation, nitration or bromination, the polymer being in the form of a film or in fibrous form and carbonizing the resultant product. Preferred groups R 1  are phenyl, naphthyl, anthryl, pyrenyl or a nitrogen-containing heterocyclic ring. Sulphur containing and oxygen containing heterocycle rings are also suggested. Specified polymers are polystyrene, poly-chlorostyrene, polydimethylstyrene, polychloromethylstyrene, poly-vinylnaphthalene, poly-vinylanthracene, polyvinylpyridine or poly-N-vinylcarbazole. In film form, the film thickness is 5 to 1000 microns, but as fibre or filament, the polymer may be monofilament fibres of diameter 1 to 500 microns or a sliver or tow consisting of from 2 to 300 such fibres. Sulphonation may be achieved by contacting the polymer with SO 3  at a temperature in the range 0 to 300 C., or by contacting with fuming sulphuric acid at 0 to 200 C., when mercury sulphate may be used as a catalyst. Chlorosulphonation may be carried out by treating the polymer with chlorosulphonic acid at - 20 to 100 C. Nitration may be carried out by contacting the polymer with conc. HNO 3  or with a mixture of cone. HNO 3  and cone. H 2 SO 4  at - 10 to 100 C. Bromination may be achieved by contacting the polymer with bromine at 0 to 200 C. The treated polymer may be carbonized by heating from ambient temp. to at least 400 C. but not more than 3000 C. at a rate of less than 500 C. The heating may take place in a vacuum or in nitrogen.

Patent GB-599926-A (GB)
Title: Improvements in and relating to the manufacture of laminated articles of shell shape
IPC: B32B27/00
Filed: 1945-04-27
Abstract: Hollow bodies of single or double curvature are made by first densifying and simultaneously bonding together by adhesive between flat platens under high pressure two or more wood laminae to form p a flat, thin, pliable board, then uniting the board with one or more other boards which may be similar or dissimilar to the first board, and simultaneously shaping the article under lower pressure.  The skin boards at the concave or convex surface of the article may be more compressed and densified than the core boards between them.  The boards to be united with the thin, pliable, densified, laminated wood boards may be made of laminae of fibrous material, e.g., wood, paper, pulp, fabric, which can be interleaved with one another or with metal foil or wire netting. Where grained laminae, e.g., of wood, are used the grains of the laminae in each board may be parallel whilst the grains of neighbouring boards are crossed.  Thermoplastic, thermosetting, or cold-setting synthetic resins may be used as adhesives.  A thermosetting or thermoplastic adhesive may be used for joining the laminae of the boards and a cold-setting adhesive for uniting the boards together.  The cold-setting adhesive may be applied to one board and a hardener to the other so that they only mix when the boards are assembled.  Shaped articles of large dimensions may be made such as bodies of motor cars or boats, propellers, hulls, or wings of aeroplanes and helicopters.  The shaping may be effected with simple formers or clamps, e.g., of wood, on which pressure is exerted by threaded spindles.

Abstract: 1461844 Burglar alarm BEVAKNINGS SECURITAS AB 11 March 1974 [12 March 1973] 10693/74 Heading G4N An alarm device comprises a first feedback shift register stage 3 at a monitored station for generating a binary one or zero signals, a transmitter 5 for converting the binary signal to an analogous signal, a receiver 6 capable of reproducing the original binary signal from the received analogous signal, a second feedback shift register stage 8 responsive to the received signals for applying control signals to a signal comparison circuit 7 which also receives the received binary signals, an alarm being actuated when the compared signals differ from one another and a timing mechanism 10 arranged to generate an alarm if the received signal is absent for a predetermined time. The shift register 3 may be periodically triggered by pulses from generator 1 or may be of the circulating type as to produce a signal pattern of binary one or zero. The transmitter 5 generates a signal of frequency f 1  for a binary one and a signal of frequency f 2  for a binary 0. Alternatively, the analogous signal may be a voltage instead of frequency. Upon unauthorized entry into monitored premises, alarm switches 36 are triggered which modify the output signal pattern of 3. There is lack of agreement between the signals compared at 7 and an alarm signal is developed on line 37. A timing mechanism 10 is periodically reset by the received signal and on interruption of the received signal e.g. by cutting wires 9, for a predetermined period an alarm signal is produced by 10.
