Title: Improvements in or relating to locks
IPC: E05B27/10
Filed: 1922-12-29
Abstract: 191,076. Caillois, P. G. Dec. 30, 1921, [Convention date]. Locks, revolving-barrel. -The insertion of the key of a revolving barrel lock not only positions locking bars longitudinally for allowing the barrel to be turned, but also imparts axial movement to the barrel to bring it into position for actuating locking mechanism when turned. In the form of device shown in the Figure, the barrel 3 integral with a ring 10 has radial slots in which can slide bars 11. These bars normally hold the barrel against rotation by engaging slots in the flange 8 of a fixed sleeve 7 in the casing 1. On inserted the key into the barrel 3 and pressing it home, the barrel first moves axially alone. The balls 15 then become wedded between the recesses provided for them in the key and the lower parts of the cam-shaped recesses 17 in the bars 11, causing the bars 11 to move axially with the barrel. The parts are so constructed that on complete axial insertion of the key the end 20 of the barrel is projected into position for actuating by rotation the locking- mechanism of a bolt or the like, and the slots 21 in the bars 11 are opposite the flange 8 to allow the barrel to be rotated by the key for this purpose. The flat end of the key engages a slot 19 in the barrel to enable it to turn it. When the parts are returned to their inital position and the key withdrawn, the springs 9, 12 return the barrel and bars to their normal position.

Patent GB-840199-A (GB)
Title: Thickened lubricating oil compositions
Filed: 1957-11-18
Abstract: A thickened lubricating oil composition comprises a lubricating oil base, predominantly consisting of a tertiary alkylated polycyclic aromatic hydrocarbon oil having an average of 2-4 alkyl substituents per molecule, and a thickening agent. Lubricating oil bases mentioned are those derived either from polycyclic aromatic hydrocarbons in which the rings form a fused ring system (e.g. naphthalene, phenanthrene, anthracene, or acenaphthene) or from such hydrocarbons in which the rings do not form a fused ring system (e.g. diphenyl) or terphenyl).  The thickeners specified are soaps (including complexes formed between fatty acid soaps and salts of aromatic acids such as benzoic acid), salts of sulphonic acids, carbon black, clays, inorganic colloids (e.g. silica, silica-magnesia or silica-alumina), estersils, and polynuclear aromatic compounds having a melting point above 200 DEG  F. and chosen from indanthrene compounds, phthalocyanines, indogen compounds and anthraquinone dyes.  Where inorganic materials are used as thickening agents, they may be waterproofed by the incorporation of surface-active agents, such as ammonia epichlorohydrin condensates (or the partial amides formed by the reaction of such condensates with fatty acids), polyalkylene polyamine/fatty acid reaction products, phenol/formaldehyde resins and aniline/formaldehyde resins.  Where an estersil is used as the thickening agent, the addition of a low molecular weight amine (e.g. ethanolamine), an alcohol (e.g. ethanol) or a ketone (e.g. acetone), while blending the estersil with the base oil, increases the thickening power of the estersil. The composition may also comprise 1-25% by weight, based on the whole composition, of an essentially non-aromatic hydrocarbon oil consisting predominantly of isoparaffinic hydrocarbons.  Such an oil may be prepared by the isomerization of paraffin wax or of mineral oil fractions containing paraffin wax.  The thickened lubricating oil composition may be a lubricating grease, a bodied hydraulic fluid or a wax-like composition for use in protecting surfaces against corrosion or other external influences.  In the examples, lubricating greases are described consisting of tertiary butylated naphthalene oil (having an average of 2 tertiary alkyl groups per molecule) thickened with indanthrene blue, estersil (silica aerogel surface-esterified with isobutyl alcohol), lithium stearate or hectorite clay (waterproofed with a tall oil acid partial amide of an ammonia/epichlorohydrin condensate).

Title: Improvements in or relating to phonograph record players
Filed: 1955-12-14
Abstract: 801,373. Automatic gramophones. ACKER, N. K. Dec. 14, 1955 [Dec. 15, 1954], No. 35849/55. Addition to 746,116. Class 40 (2). In a phonograph player as in the parent Specification an electric drive 61, 62 is coordinated with a system of selector switches 71 and relays 80, 90 which energize the solenoid 17 of an actuating member 117 to set the storing members 15. The disc 18 carrying the actuating member 117 is set in rotation by motor 61 upon the temporary closure of a switch 84 which operates relay 80 and establishes a hold-on circuit therethrough by means of a contact 81. As the disc 18 rotates, a spring contact thereon passes over contacts 64 on a disc 63 until circuit is completed through a pre-operated selector switch 71, whereby the relay 90 is operated and the solenoid 17 thereby energized to operate the member 117 and raise the storing member 15. The operation of relay 90 also breaks the hold-on circuit of the relay 80 and therefore the circuit of the motor 61. A modification is shown in Fig. 3 in which a smaller number of keys 71 are connected to flat selector contacts, the final selection being completed by the operation of one of the bank of keys 71 connected to the relay 90. It is also proposed to replace the keys 71 by a telephone calling dial.
