Abstract: 756,821. Photographic cameras. VOIGTLANDER AKT.-GES. Oct. 14, 1954 [Oct. 16, 1953], No. 29641/54. Classes 97 (1) and 98 (1). A locking arrangement for securing exohangeable objectives or auxiliary devices on optical apparatus which incorporates a snap lock having an inclined surface on a locking tooth and a spring holding the latter in the locking position, comprises one or more bell-crank levers 8 pivoted on the exchangeable part 7, of which one arm 11 carries a locking element movable perpendicular to a straight line guide 55 for the exchangeable part and of which the other arm 13 is free and carries an actuating element which is movable in the direction of guide 55. As shown, the shutter casing 1 of a photographic camera 2 has an exposure setting ring 3 and a threaded opening 4 for a socket 5. The straight guide 55 is formed on socket 5, which is also formed with a lip 6. Bell-crank levers 8 are pivoted at opposite sides of an exchangeable objective mount 7, and each is urged by a spring 10 to urge a tooth 111 on its arm 11 towards the socket 5. The front surface 15 of the tooth is sloped to ride over the lip 6, which is then engaged by the sloping rear face 16 of the tooth whereby an abutment shoulder 17 on mount 7 is held securely against the lip 6 with sufficient friction to enable the socket to be turned by gripping the edge 18 of mount 7 and turning it. To this end, edge 18 is knurled axially. The ends 12 of arms 13 of levers 8 project proud of edge 18 and are knurled circumferentially, so that they may readily be gripped by the fingers to rock levers 8 to release them from lip 6. The objective mount 7 may then be pulled off.

Patent GB-1532363-A (GB)
Title: Method of synchronising coding devices for data transmission systems
IPC: H04L9/12
Filed: 1977-07-14
Abstract: The devices at the transmitting and receiving end are in each case controlled by a clock generator, these clock generators being synchronised at the start of each transmission with the aid of alignment signals. A first alignment signal (KW1) initiates the transmission of cipher signals (SKZ) from the transmitter to the receiver by means of which a cipher generator at the receiving end is programmed. The transmitter transmits a second alignment signal (KW2) in encrypted form (KW2 VS) to the receiver which, following correct decryption of the second alignment signal, transmits a third alignment signal (KW3) as an acknowledgement to the transmitter which then, with a fourth alignment signal (KW4), initiates the transmission of the encrypted message to the receiver. Incorrectly received second, third or fourth alignment signals effect the resetting of the cipher devices by means of circuits (E1, E2) to a basic setting (GSt) and a repetition of the described method steps. <IMAGE>
Patent GB-767592-A (GB)
Title: Improvements in or relating to the refining of hydrocarbon oils
IPC: C10G27/04
Filed: 1953-10-27
Abstract: A virgin mercaptan-containing hydrocarbon oil, which may contain up to about 25 per cent by volume of cracked components, is refined by contact with a catalyst comprising cobalt molybdate or alumina, molybdenum oxide on alumina or a mixture of tungsten sulphide and nickel sulphide, under conditions, including a temperature in the range 400-700 DEG F. and a pressure below 500 lbs./sq. in. gauge such as to result in partial sweetening of the oil.  The contacting is carried out in the absence of extraneously-added or recycled hydrogen and in the absence of extraneously-added hydrogen donor material. The partially sweetened oil, after removal of hydrogen sulphide, for example by washing with caustic alkali solution, may be further sweetened by washing with caustic alkali solution in the presence of added air. Virgin naphtha, blended if desired with up to about 25 per cent by volume of cracked naphtha, may be contacted with the catalyst under the specified conditions and the partially sweetened naphtha washed with caustic soda solution.  The naphtha may then be further sweetened, by washing with caustic soda solution in the presence of added air and in the presence of an oxidation inhibitor such as phenylene diamine, to produce a doctor-sweet motor fuel.  Apparatus is also described in which crude petroleum is distilled to yield various fractions including a heating oil fraction and a gas oil fraction.  The heating oil fraction is contacted with the catalyst under the specified conditions to yield a partially sweetened heating oil, which is washed with caustic alkali solution to remove hydrogen sulphide and then further sweetened by washing with caustic alkali solution in the presence of added air.  The gas oil fraction from the crude petroleum is cracked to yield various products including a cracked heating oil fraction.  This is washed with caustic alkal solution and then blended with the sweetened heating oil mentioned above.

Abstract: 711,474. Fumigating. DEODOR-X HYGIENE SERVICES. Ltd. Jan. 23, 1952 [Dec. 7, 1950], No. 29974/50. Class 81(1) In a method of fumigating by exposing absorbent material containing a fumigant to the atmosphere, a device is employed comprising a portable self-supporting absorbent receiver which, for the purpose of absorbing fumigant in the receiver and for storing the receiver when not in use, is provided with a sealable container and self-sealing valves for charging the receiver with fumigant and discharging air from the container. As shown a sealable container 1 has a removable cover 4 provided with two self-sealing valves 7 and carrying an absorbent fumigant receiver in the form of a plurality of discs 16 of absorbent material such as paper or lightly compressed pulp separated by spacers 17 and assembled on a central rod 18. In operation the absorbent receiver carried by cover 4 is inserted into the container 1 and the cover screwed down firmly so as to seal the container. The outlet connection of a fumigant supply container is attached to a length of hose the open end of which is situated a safe distance from the operator. When the container has been sufficiently charged the connections are removed, the valves 7 closing automatically. Sealing caps 21 may then be placed over the valves 7 and a cap 19 over the container 1 which may then be sealed by affixing a lead seal to lugs 22 and 23 on container 1 and cap 19 respectively and stored until ready for use. For use the container is transported to a space to be fumigated, the lead seal broken and the cap 19 is removed from the container.

The invention relates to a method of regulating flow of working fluid to a well-drilling turbine in which an accumulator having a variable volume is disposed upstream of the turbine and adjacent thereto and through which the turbine working fluid is caused to flow. In Fig. 1 the accumulator is in the form of an expansible tube 2 formed of rubber or like material, the tube being disposed within a rigid tube member 1 which forms part of the drill column, the turbine being mounted at the lower end of the assembly shown. The tube member 1 is formed with apertures 8 whereby the space between the expansible tube 2 and the rigid tube 1 is connectible to the space between the tube 1 and the borehole. The expansible tube is rigidly connected at its ends to the drill column, being shown in its unexpanded condition at the right of Fig. 1 and in its expanded condition in which it is in contact with the rigid tube 1 at the left of Fig. 1. In a second embodiment the expansible tube is fixedly mounted at its upper end but is arranged for axial sliding movement at its lower end. In a further embodiment two coaxial expansible tubes are provided, the inner tube first contacting the outer tube and then both tubes expanding together.
