Filed: 1955-05-03
Abstract: A fireproof protective coating for wood or other combustible material, and comprising magnesite, magnesium oxide, magnesium chloride, a mixture of magnesium oxide and magnesium chloride, a silicate, or Portland cement, incorporates as a pigment or pigments able to withstand high temperature, and exhibiting high reflection of infra-red rays of wavelengths between 0,8 and 10 microns, one or more of the sulphides, selenides, or tellurides of non-radioactive elements of the second group in the Periodic table preferably of zinc, cadmium or mercury.  The pigment or pigments may be activated by introducing into the crystal lattices thereof, atoms of copper and/or silver and/or gold and/or nickel and/or cobalt and/or a rare earth metal.  In addition the coating may contain as additional pigment or pigments one or more of the sulphides, selenides, or tellurides of thallium, arsenic, antimony, bismuth, or lead.  The pigment or pigments may be provided with an inorganic protective covering, e.g. of sodium or potassium silicate, or beryllium oxide, or may be treated with temperature-resistant silicones.  The fireproof coating may also comprise organic colouring substances which may be embedded in synthetic resins, e.g. polyvinyl esters, polystyrenes, coamorone-indene compounds, and the condensation products of aldehydes, phenols, and cresols, and of polyalcohols and polybasic acids, silicones and other substances.  The pigments are preferably used in association with a wetting agent.  In examples coatings are prepared comprising (1) magnesium oxide, magnesium or potassium chloride, zinc and cadmium sulphides, and ultramarine green (2) calcium oxide, silica, alumina, ferric oxide, cadmium sulphide, cadmium selenide, magnesium or potassium chloride, and ultramarine blue (3) magnesium oxide, magnesium chloride, calcium sulphide, strontium selenide, europium and samarium oxalates, potassium silicate, potassium chloride, zinc sulphide, and cadmium sulphide, (4) magnesium oxide, magnesium chloride, zinc sulphide, cadmium sulphide, copper, cobalt, and heat-treated lead sulphide.

Abstract: 969,450. Securing sockets on shafts. CHICAGO PNEUMATIC TOOL CO. April 2, 1963 [May 25, 1962], No. 12961/63. Heading F2U. [Also in Division B3] The socket 27 is secured to the shank 26 of an impact wrench by splines 41, 44 and a detent 55 in a transverse bore near the end of the shank, the inner end of the detent being of double frustoconical form and bearing directly against a conical recess 71 near the end of a hexagonal-section axial plunger 62 urged forwardly by a compression spring 65. To release the socket 27 the plunger 62 is pushed rearwardly against the spring 65 to allow the end of the detent 55 to move radially inwards into contact with a second recess 67 at the end of the plunger, whereby the outer end 57 of the detent moves clear of the splines 44 to allow the socket to be withdrawn axially from the shank. The spring 65 bears against a plug 38, a counter spring 36 and fixed abutment rod 34 limiting the rearward movement of plunger 62 during removal of the socket to prevent inadvertent detachment of the detent 55. In a modification, Figs. 12-15 (not shown), the plunger 62 and spring 65 are housed in a closed bore in the shank 26, the plug 38 being omitted. Specifications 784,269 and 874,834 are referred to.

An extrusion billet is pierced whilst enclosed in the billet container 14, Fig. 1, of an extrusion press with the die orifice closed by an hydraulically actuated retractable plug 33<SP>1</SP>, Fig. 2. The billet is pierced by a mandrel 11 actuated by piston 9 working in the main press piston 5. Throttling means are provided for slowing the piercing mandrel. After piercing, the closure plug is moved into position 33 and the pierced billet, which may be of steel, is extruded immediately into a tube by means of extrusion ram 7. Retraction means 12, 13 are provided for the ram 7. The plug 33 is rockable about a pivot 32 by a cylinder 46. When in a position in alignment with the die the plug 33 engages a recess 50 in a lifting piston 51 which pushes the plug into the die orifice. A run-out channel 40 is secured to the plug 33 so as to be moved into the die axis when the plug is moved into its inoperative position. In a modification, Fig. 3 (not shown), the lifting piston is rigid with the plug and pivotal therewith. A lubricant disc of a glass-graphite mixture is placed between the billet and die during piercing.

Title: Rotary positive displacement machine
IPC: F01C1/08
Filed: 1972-03-21
Abstract: 1376352 Rotary positive displacement machines LE MILLER Jnr 21 March 1972 13160/72 Heading F1F AXIAL-BLADED EMBODIMENT A rotary positive displacement machine such as a compressor comprises a first annular housing member 11 and a second worm-like member 12 located therein, the member 11 having an internal helical thread and the member 12 an external helical thread, the threads extending for one and one quarter turns and having their apices immediately adjacent each other to define a "pass" B, Fig. 3, therebetween. A parallel array of axially extending helical blades 13 are disposed between the members 11 and 12 for engagement therewith, the blades each having five-eighth's of a turn and being individually rotatable about their longitudinal axes. In the embodiment shown there are eight blades 13 equally spaced angularly and each supported for rotation relative to the members 11, 12 in a common rotor 20. The surfaces of members 11 and 12 are epitrochoidal and are the loci of the edges of the blades 13 as the rotor moves through 360 degrees and the blades are simultaneously rotated about their own axes through a half turn in an opposite direction to rotor rotation. Thus, if an axial flow of pressure fluid is applied to one, intake, end of the blades 13, then variable-volume chambers are formed between adjacent blades and the fluid pressure acts on the blades to move them relative to the housing members 11, 12, thus imparting a rotary motion to the rotor 20 and output shaft 28, fluid being exhausted from the other end of the blades. Similarly, the shaft 28 can be rotated and the machine used as a pump or compressor. Embodiments with two and three blades are described Figs. 5, 6 and 7, (not shown) and the housing members can have two, three or more threads Figs. 8 and 9, (not shown). The mounting of the blades on the rotor can be arranged to provide the correct rotation of the blades for a corresponding rotation of the rotor, the guiding of the rotor blades between the housing members thus being independent of the engagement therebetween Figs. 10, 11 (not shown). RADIAL-BLADED EMBODIMENT Helically configured blades 313 are disposed radially on a rotatable mounting member 320, the edges or apices of these blades being free to engage threaded housing members 311, 312. Each blade is individually rotatable on bearings 326, 327, has a relatively thin cross-section, and is turned through a half-turn over its length. Each housing member is contoured with at least one spiral thread. Cooperation between the blades and housing members is similar to that for the axially-bladed embodiment and a guiding arrangement for the blades can also be provided as before.

The mixture 20 comprises polyvinyl chloride with a plasticizer comprising, e.g. di-2-ethylhexyl phthalate, dioctyl sebecate or tricresyl phosphate. Steam is circulated through an autoclave 7 and the mould 1 subsequently cooled by spraying with cold water from a pipe 11.

Abstract: 399,750. Fused silica. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Thomson, E. ; 22, Monument Avenue, Swampscott, Massachusetts, U.S.A.) May 9, 1933, No. 13484. Convention date, May 10, 1932. [Class 56.] Relates to the method of making a massive article of fused silica, such as a mirror for an astronomical telescope, by depositing fused silica on a base by means of a flame, as described in Specification 296,059, [Class 56, Glass]. According to the present invention, a layer of transparent vitreous silica is deposited on a support, and the rate of deposition is then increased to form a backing of less density on the transparent layer. The support 5, which may have any suitable configuration, consists of a refractory material and is enclosed in a furnace by which it is heated to a temperature of about 1000‹ C. Comminuted silica is projected by a burner 7 against the support until it forms a layer 4 of transparent vitreous silica. After this layer has attained the desired thickness, the rate of feed of the silica to the burner is increased so that a backing 15 is formed which is less dense than the transparent silica and may contain gas bubbles. Finally, the completed composite article is removed from the support and the surface of the layer 4 is ground and polished. Specification 399,749 is referred to.
