Title: Omnidirectional inertia switch
IPC: H01H35/14
Filed: 1976-07-05
Abstract: 1505796 Inertia switches D T MEISENHEIMER 5 July 1976 [6 Oct 1975] 27826/76 Heading H1N An omnidirectional inertia switch comprises a member having a conductive spherical surface, a conductive spherical movable mass concentrically supported by a resiliently deformable member substantially surrounding it and having substantially uniform deformability in all directions such that the application of predetermined inertial force causes the mass to contact the spherical surface. Two embodiments are described. In the first embodiment a spherical cavity in a housing contains a hollow spherical elastomeric member inside and by which a conductive hollow spherical movable mass is supported slightly spaced from a concentric conductive stationary sphere which is adjustably supported by two diametrically opposed posts passing through appropriate apertures in the hollow spherical mass and the hollow elastomeric member. The housing and the hollow spherical members are each formed as two halves which are joined together to assemble the switch. The second embodiment is more simple and the movable mass is centred in a spherical cavity by the interposition of a polygonal large mesh net of elastomeric material through the openings in which it can contact the inner surface of the cavity which is formed in a conductive housing or is plated with a conductive material.

Filed: 1922-10-23
Abstract: 195,331. Vaughan, W. H., and Wood, F. Oct. 23, 1922. Geared pulley hoists; self-sustaining gear.- Comprises an arrangement of self-sustaining gear, with partial release for braked lowering, in pulleyhoists of the type driven by worm gearing and provided with self-sustaining gear comprising ratchet-and-pawl mechanism carried on the worm shaft. The rotation of the hand chain wheel F in the direction for hoisting moves it outwards laterally on the screw D until dogs e, f engage to drive the worm, the thread on which is of the opposite hand to that on the screw D. During hoisting the load thrust on the worm jams the friction disc K and ratchet wheel L together, so that they rotate as one member. When hoisting ceases, the wheel L is held by a pawl, and the friction between the members K, L sustains the load. On rotating the hand-wheel F in the direction for lowering, the wheel moves inwards on the screw and by thrusting against the steel washer g moves the worm shaft axially sufficiently to relieve the pressure between the members K, L.

Title: Lubricating composition
Inventor: GIBSON JOHN ANDERSON
Filed: 1956-09-21
Abstract: Synthetic ester lubricating oils contain as an antioxidant a minor proportion of an oil-soluble bisphenol of the formula <FORM:0818967/III/1> where R1 is hydrogen or a C2-C5 alkyl group, R2 is a C2-C5 alkyl group and R3 and R4 each represent one or more alkyl groups.  The ester oil may be a simple organic ester; preferred, however, are complex esters prepared from at least one polyfunctional alcohol and at least one polyfunctional acid and containing no free hydroxyl or carboxyl groups.  The acids may contain up to 22 carbon atoms and include adipic azelaic and sebacic acids.  The alcohols are preferably alkylene and polyalkylene glycols -the glycols preferably being diethylene to decethylene glycols and the polyglycols being polyethylene glycols of molecular weight about 200; other polyfunctional alcohols include pentaerythritol and trimethylol propane.  Monofunctional acids or alcohols may also be present, the latter containing 4-18 carbon atoms, e.g. 2-ethyl hexanol, iso-octanol and oxo alcohols such as nonanols. Particularly useful esters have the structure: <FORM:0818967/III/2> These complex esters may be blended with dialkyl esters of C2-C4 dicarboxylic acids, straight or branched chain, saturated or unsaturated and containing, if desired, one or more ether or thio-ether linkages such as adipic, azoleic and sebacic acids, the alcohol residues containing 1-40 carbon atoms, e.g. 2-ethyl hexanol, iso-octanol and oxo alcohols. They may also be blended with formals, polyformals, acrylates or methacrylates or their polymers.  The oil used may have a kinematic viscosity of 1.5-15 at 210 DEG  F.  In the bisphenol antioxidant the groups R3 and R4 preferably represent one one or more tertiary alkyl groups.  Preferred amples are 2,21-bis (4,6-di-tert.-butyl phenol)-1,1-n-butane and 2,21-bis (4-tert.-butyl-6-methyl phenol)-1,1-n-butane and they preferably comprise up to 5 per cent by weight of the composition.

Patent GB-452390-A (GB)
Title: Improvements in or relating to the heat-treatment of magnesium alloys susceptible to precipitation hardening
IPC: C22F1/06
Filed: 1935-10-19
Abstract: Magnesium alloys susceptible to precipitation hardening are homogenized by first heating the alloys to temperatures which are below the melting point of the metastable constituent, but are sufficiently high to induce homogenization, until the bulk of the heterogeneous constituents surrounding the primary crystals have been dissolved in the latter and then heating the alloys at or above the melting point of the metastable constituent but below the temperature of incipient fusion until the solution of the heterogeneous constituents in the primary crystals has been completed.  The first heating may be caused to merge into the second heating by gradually increasing the temperature of the first heating, the merging taking place only when the bulk of the heterogenous constituents have already dissolved.  The alloys which are susceptible to precipitation hardening are binary alloys containing aluminium, zinc, lead, tin or bismuth or multiple alloys containing two or more of such elements, the magnesium content of all such alloys being not below 80 per cent. Other elements incapable of causing precipitation hardening such as silicon and manganese may be present in amounts up to 2 per cent. In the treatment of alloys containing 3-12 per cent of aluminium, the first heating is carried out at temperatures below 436 DEG  C. and the second heating at or above 436 DEG  C.  In an example, an alloy containing 8 per cent of aluminium and 0,3 of manganese was first heated for 5 hours at 420 DEG  C. in an electric furnace containing an atmosphere of carbon dioxide, and the temperature was then raised to 436 DEG  C. and maintained thereat for 16 hours. The alloy may then be annealed for 16 hours at 150 DEG  C. to improve further its mechanical properties.

Title: Improvements in or relating to x-ray tubes
IPC: H01J35/12
Filed: 1946-09-27
Abstract: 617,373. X-ray tubes. PHILIPS LAMPS, Ltd. Sept 27, 1946, No. 28918. Convention date, March 15, 1943. [Class 39 (i)] An X-ray tube is provided with a thin metal plate anode, the side of the anode remote from the side struck by electrons being in intimate thermal relation through a layer of liquid having a high thermal conductivity with a cooling body whose surface moves continuously over the surface of the anode. The X-ray tube 1 has a metal portion 3 provided with an aperture 4 closed by a thin tungsten plate anode 5. The heat produced in the anode 5 is transmitted to a rotating cooling body 8 by means of a liquid, for example a liquid metal or metal alloy such as mercury, which completely fills the casing 6 and is present between the anode 5 and cooling body 8. The heat is conveyed by the liquid to the wall of the casing 6 which is provided with cooling ribs 7 and may be provided with an envelope, a liquid or gaseous cooling agent being led through the space between the casing and the envelope. In an alternative arrangement the rotating body 8 may be cooled by exposure to the air. The rotating body 8 may be a cylinder or a disc and as shown is a copper disc in the form of a frustum of a cone fixed to a motor-driven shaft 9 which passes through a gland 10. The rotating body 8 may be hollow with separate cooling liquid entering and leaving it along its axis of rotation. When the area of the anode 5 struck by the electrons has an elongated shape it is advantageous if the direction of motion of the rotating body 8 over the anode 5 is at right-angles to the longest dimension of the area of impact of the electrons. The metal portion 3 is connected to a glass portion 11 having a re-entrant part 12 carrying a mounting 13 containing a cathode 14. The casing 6 is fastened to a thickened end wall of the metal portion 3 by a flanged connection 18. The X-rays generated are transmitted through a thin glass window covering an aperture 22.
