Title: Improvements in surface ornamentation
IPC: B05D5/06
Filed: 1927-11-25
Abstract: 285,471. Simon, L. L. Feb. 18, 1927, [Convention date]. Omamenting.-A process for ornamenting the surface of wood, metal, paper, cardboard, pottery, glass, fancy shoe leather, textiles, rubber, or plaster, or articles made of rattan or straw, comprises the application to a surface already provided with a coloured design consisting, for instance, of a coloured glue solution, of a layer of crackling enamel, varnish, or lacquer, in which, on drying, fissures are formed, whereby parts of the design are exposed, and, together with the grains of the enamel, provide an ornamental appearance. The design may be applied by dyeing, printing, or painting, or the process may be used for producing a new ornamental design on surfaces already bearing a design. The surface may, first of all, be coloured uniformly, a layer of colourless transparent varnish may be interposed between the design and the enamel, and a final protective coating of varnish may be applied.

Title: Photographic Type-Composing apparatus having a Drum-Shaped Character Font
Inventor: MCCALL JOHN MARSHALL
IPC: B41B21/16
Filed: 1967-07-11
Abstract: 1,180,628. Photographic type-composing. FAIRCHILD CAMERA & INSTRUMENT CORP. 11 July, 1967, No. 31915/67. Heading B6W. A photographic type-composing machine has a drum-shaped font carrying a plurality of characters arranged in rows parallel to the drum axis, code controlled stepping means for rotating the font about its axis to select a row, a rotatable reflector for selecting a character from a selected row, a lens to form an image of the character, a further rotatable reflector for directing the image of a selected character into the required position on a light sensitive surface and means for momentarily illuminating the chosen character. A character font 12 having a dished-drum shape is rotatable about its axis to bring one of a plurality of axially aligned rows of character transparencies into a position where it may be illuminated by light from flash lamp 42 directed into the drum by condenser lens 39 and prism 40. A required character is selected from the row by pivotal motion of mirror 16 which directs light from the character through image forming lens 43, variable focal length optical system 44, 46, and projection lens 78 on to a pivotable mirror 96 and then on to recording surface 104. Character spacing is effected by continuous pivoting of mirror 96. The position of mirror 96 is detected by a secondary light beam from lamp 108 which is directed by mirror 120 (on the same pivoting shaft as mirror 96) on to an optical grating 126 and then back to a photo-cell 128 which counts pulses produced by the sweeping of this secondary beam over the grating as the mirror 96 sweeps surface 104. The speed of sweep of mirror 96 is variable according to the point size of characters being composed as determined by the position of lenses 44 and 46. A required character is read from a tape and appropriate signals applied to stepping motors 24 and 36 to position mirror 16 and drum 12 accordingly. The positions of the drum and mirror are monitored by coded spot digital transducer tracks, e.g. 26, sensed by photocells, e.g. 30. As mirror 96 sweeps surface 104 arm 82 riding on cam 84 adjusts the position of lens 78 to maintain the focus. Recording film or paper 104 is fed by motor 106 to provide line spacing. The tape may be read a first time for justification calculations and a second time to effect machine operation. In an alternative embodiment flash illumination may be directed on to reflective characters on a non- reflecting ground.

Filed: 1925-12-21
Abstract: 263,300. Voigt, P. G. A. H. Dec. 21, 1925. Condensers.- The relative position of the electrodes 1, 3, Fig. 1, of a condenser telephone is de termined by the elasticity of a thin cushion of air or other gas 4, all other forces, such as the restoring-forces due to the mounting of the movable electrode, 3, being relatively negligible at acoustic frequencies. The fixed electrode consists of a curved metallic plate damped with felt or other material 2 and screwed to an insulating base 7, and the movable electrode consists of thin aluminium foil. Short circuits are prevented by the insertion of a piece of silk cloth, which is kept dry by drying the air round the microphone or drying the air cushion before or after assembly, for example by small air passages communicating with a tube containing calcium chloride. Electric interference is prevented by a screening case 13. Alternatively, both electrodes consist of thin foil.

Title: Processes for separating solid substances from a mixture thereof with oil
Filed: 1952-12-19
Abstract: Solid hydrocarbons, for example paraffin wax, or solid complexes of hydrocarbons with urea or thiourea are separated from a mixture thereof with oil, with or without admixture with an oil-solvent by contacting the mixture with an auxiliary liquid immiscible with the oil, such as an aqueous liquid, under such conditions that the solid substance enters the auxiliary liquid phase or the auxiliary liquid phase displaces the oil phase from the solid substance.  The oil phase is separated from the auxiliary liquid phase and the solid substance from at least a part of the auxiliary liquid phase, and at least a part of the auxiliary liquid phase already used is brought into preliminary contact with a mixture of oil and solid substance to be treated. When dewaxing oil the mixture may be cooled, for example to 30 DEG  C., before addition of the auxiliary liquid.  The solid substance may be separated from the auxiliary liquid phase by filtering or decanting and the solid substance then melted and the remaining liquid separated.  The oil solvent specified is dichlorethane and the auxiliary liquid may contain a surface-active substance, such as sodium heptadecyl-9-sulphate, and a demulsifier, such as magnesium sulphate.  Specifications 733,067, 734,132 and 737,483 are referred to.

Title: Improvements in or relating to containers for growing plants
IPC: A01G27/02
Filed: 1957-10-16
Abstract: 874,729. Plant pots ; watering plants. BRACEY, R. C. Oct. 16, 1958 [Oct. 16, 1957], No. 32386/57. Class 6(2). A receptacle for growing plants comprises a container 3 for the plant in communication via an aperture 15 with a closed liquid storage tank 9. In the simplest form of the invention, when the level of water inside the container 3 drops below the opening 15, air is drawn through the contents of the container, through the opening 15 into the tank 9, to replace the water which then flows into the container. Alternatively, an open tube 16 can be mounted in the re-fill cap 12 of the tank to provide means whereby air may enter the tank 9. In this case a spring-loaded valve member 18 is preferably mounted within the tank 9 to co-operate with a seating 21 when the tube 16 is withdrawn, so that when the cap 12 is removed and the tank 9 re-filled, liquid is prevented from flowing freely through the aperture 15. The lower end of the tube is cut away as at 24 to ensure that it is not sealed by the member 18. According to further modification, the tank 9 may be separate from the container 3 and be in communication therewith via piping or a wick, and in this case the tank may be used to supply more than one container with liquid. Mention is made in the Specification of the possiblity of covering the container 3 with a tray holding water or nutritve solution, which by its evaporation and absorption through the leaves of the plant will reduce the amount of liquid or food otherwise required by the plant.

Abstract: 1,096,704. Universal joints. EATON YALE & TOWNE Inc. July 29, 1965 [May 10, 1965], No. 32484/65. Heading F2U. A universal joint, particularly for use at the ends of-an automotive vehicle propeller shaft, comprises three nested frusto-conical spring units cold-press-fitted in driving and driven members 7, 8, each spring unit including a plurality of intercalated helical springs, and the springs of the inner, intermediate and outer spring units 20, 21, 22, being respectively left, right and left-hand. In the spring units 20, 21, 22 respectively, there are 4 to 6 (preferably 5) rectangular cross-section, and 5 to 7 (preferably 6) circular cross-section wire springs, with lead angles, prior to assembly, of 9 to 16 degrees (preferably 13À8 degrees), 6 to 12 degrees (preferably 9À2 degrees) and 6 to 12 degrees (preferably 9À5 degrees), and spring indices (mean coil diameter divided by radially measured wire thickness) of 7 to 11 (preferably 8À8), 9 to 13 (preferably 10À6) and 11 to 15 (preferably 12À5). In assembly, the intermediate and outer spring units 21, 22 of substantially equal length are fitted together with radial interference and with adjacent spring turns axially spaced. The inner spring unit 20 is fitted with radial interference, and with adjacent spring turns axially spaced, into the intermediate spring unit 21, and extends beyond the latter. This assembly is then pressed into recesses 14a, 18 of the driving and driven members 7, 8 with a radial interference. On release of the pressing compression, the unit 20, in tending to return and expand to its original state, tends to extend the units 21, 22, so that the unit 20 and the units 21, 22 are put in compression and tension respectively, thereby increasing the radical interference between the units. The driving and driven members 7, 8 are preferably of softer material than the springs so that on assembly the outer walls of the recesses 14a, 18 are deformed to produce recess ridges engaging between the peripheries of the outer spring turns, and projecting ends of the springs bite into the bases of the recesses. The ends of the springs are flattened before assembly to provide enlarged portions for greater penetration into the recess walls. To minimize snagging of the spring ends on assembly, the spring ends of adjacent units are overlapped. Centring means for, and allowing relative axial movement of, the driving and driven members 7, 8 comprises a ball extension 35 of the member 8 received in a tube 31 connected to the member 7. A lubricant-retaining bellows-type boot 40 of yieldable rubber-like material is secured to the driving and driven members by clamps 43, 44.
