Patent GB-415625-A (GB)
Title: Improvements in and relating to a safety key for locks with tumblers
IPC: E05B19/00
Filed: 1933-12-07
Abstract: 415,625. Lock keys. RECHT, O. C., 129, Gothersgade, and HOLM, A. LOUBERG-, 27, Gl. Vartovsvej, Hellerup, both in Copenhagen. Dec. 7, 1933, No. 34492. [Class 44.] A number of tumbler-operating cam members are normally free to slide and turn on a key shank, but can be interlocked and locked on the shank in a number of different settings by means of serrations or pins and sockets on their abutting ends. Only one setting however is effective to operate the lock. In the divided-pin tumbler form of lock shown the pin tumblers 16 are operated by cam members comprising projections and depressions on rings 10-12 which are freely mounted on a key shank 3 but after being set by hand to the particular combination required are locked by a cap 8 on the end of the shank which is caused to rise by the grip of the operator's fingers moving a wing 4 fixed on the shank and so moving a lug 5 of the shank along a helical groove in the interior of a tubular part of the key handle. On the operator releasing the wing 4 the shank is drawn down and turned by a retracting spring 6 and a peripherally acting detent 21 housed in the lock barrel 13 prevents the shank being rotated in the reverse direction. Thus if the key is inadvertently left in the lock the combination cannot be discovered by attempting to actuate the wing 4 to raise the cap 8 and so to re-lock the cam members 10-12 before withdrawing the key ; the key must be withdrawn in the existing state, that is, with the cam members not locked and thus the combination is dispersed by casual forces moving the members 10-12 during the withdrawal. The dispersal may be effected by giving a helical form to the grooves which are provided in the barrel 13 to accommodate the projections on the cam members 10-12.

Abstract: 758,320. Magnetic compositions. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 30, 1954 [Nov. 30, 1953], No. 34697/54. Class 38 (2). [Also in Group V] A material exhibiting permanent magnetism comprises particles of a substance having the formula MeO, xFe 2 0 3 , where Me is lead, strontium or barium and x lies between 3 and 8 held together by an organic binder. Preferably, x lies between 5 and 7. Between 2 and 30 per cent by weight of the binder may be mixed with 70 to 90 per cent by weight of the magnetic substance, the favoured proportions of binder being between 8 and 15 per cent. To make a suitable material BaCO 3  is mixed with Fe 2 O 3 , the mixture is ground, sintered, reground, sifted, mixed with the binder, inserted in a mould subjected to a magnetic field, compressed and heated to polymerize the binder. The binder may be thermosetting or thermoplastic, e.g. a phenoplast, amino-plast, acrylic resin, polyester or phenolic resin. The substance sold under the Registered Trade Mark " Araldite " may be used. The final moulding may be done in a non-magnetic steel body 1, the mixture being inserted in a cavity 5 between two hardened steel arms 8, 9, forming the poles of a soft magnetic circuit energized by both D.C. and A.C., the field produced by the latter causing the magnetic particles to vibrate and thereby assisting their turning under the influence of the field of the former.

Abstract: 798,617. Gas turbine jet-propulsion plant. SOC. RATEAU, and ANXIONNAZ, R. Nov. 13, 1956 [Nov. 23, 1955], No. 34709/56. Class 110 (3). [Also in Groups XXXIII and XL (a)] In an aircraft propulsion system operating with hot air or gas, at least two heat sources are provided, one being a combustion apparatus and the other a nuclear reactor, and means are provided to set either or both heat sources into operation as required. In the gas turbine jetpropulsion unit shown in Fig. 1, air from the compressor 1 flows through the nuclear reactor 2, the combustion system 3, the turbine 4 and the propulsion nozzle 5. The combustion system 3 may be used at low altitudes by supplying fuel thereto in the normal manner, whereas at high altitude the reactor 2 may be set in operation by withdrawing the moderator. The reactor 2 and combustion system 3 in Fig. 1 are each mounted concentrically around the turbine-compressor shaft, but in a second arrangement, Fig. 2, the reactor 2 is mounted below the shaft and three combustion chambers 3 are mounted above the shaft in the same transverse plane, air from the compressor being caused to flow either to the reactor or to the combustion chambers by operation of valves 6, 6a. An exhaust reheat device 16 may be provided downstream of the turbine. In a third embodiment, the invention is applied to a gas turbine-propeller unit, the reactor 2 and combustion system again being mounted in series, but both offset below the turbine-compressor shaft. In Fig. 4, air from the compressor is heated indirectly in the heat exchanger 8 by means of an auxiliary fluid such as liquid metal which is heated in the reactor 2. One or more combustion chambers 3 are disposed downstream of the annular heat exchanger 8. With this arrangement, a single reactor may be mounted in the fuselage of the aircraft and connected to a heat exchanger 8 mounted in each propulsion unit. In a gas turbine jetpropulsion engine of the by-pass type, Fig. 7, air from a low-pressure compressor 11 is divided, some passing through a high pressure compressor 1, reactor 2, combustion equipment 3, turbine 4 and propulsion nozzle 5, while the remainder flows through duct 12 and reactor 2a to a propulsion nozzle. The reactor 2a in the duct 12 may be omitted and the reactor 2 constructed as an annular doubleflow unit, the combustion system being disposed around the nuclear reactor. A two-shaft arrangement is employed in this embodiment. The invention is shown applied to a ram-jet unit in Fig. 8, a heat exchanger 8 being disposed in the ram-jet duct which transfers heat from the nuclear reactor 2 to the air stream by means of an auxiliary fluid such as liquid metal. A distributer 14 and nozzles 15 are provided for supply of normal fuel. In a further embodiment an annular ram-jet unit is disposed around a turbo-jet unit such as that shown in Fig. 1, the air stream flowing through the ram-jet duct being heated either in an annular reactor or in an annular combustion section. In all embodiments, the nuclear reactor and combustion system may be used simultaneously.
