Title: Improved method of and means for forming a cavity when making concrete structures
Inventor: GRIX PETER ALAN
IPC: B28B7/34
Filed: 1969-04-01
Abstract: 1286146 Destructible cores P A GRIX 31 March 1970 [1 April 1969] 16864/69 Heading B5A [Also in Division E1] A destructible core B of, for example, foamed polystyrene, is carried within a metal mounting member A comprising a base portion 1, a pair of limbs 2 diverging from the base portion, and a pair of fingers 5 projecting from the ends of the limbs and engaging the rear surface of the core. The base portion is provided with a central removable portion 7 and the limbs, when the base portion is disposed vertically, slope downwardly. In use, the mounting member is fixed against the vertical side of a mould or shuttering, the core positioned therein, and the concrete cast to a level at which the downwardly sloping limbs are embedded and the upper surface of the core is visible. Subsequently the core is burnt out to leave a peripherally reinforced cavity into which the lower ends of posts or the like may be cemented. In the embodiment shown in Fig. 12 a concrete foundation is cast in wooden shuttering to the side walls of which is attached a core which is subsequently removed to leave a cavity D. The base portion is flush with the edge of the foundation and the removable portion has been removed to allow the laterally projecting end F1 of a baluster F or the like to be inserted through the hole 5 into the cavity where it is secured by a grouting cement. If desired the portion 7 need not be removed, the end of a straight pole or rod being located within the cavity and grouted in position. In alternative embodiments in which the base portion 1 is embedded within the foundation, a spacer block of foamed polystyrene is interposed between the mounting member and the shuttering and, after removal of the spacer block and core, the base portion lies inwardly and not flush with the edge of the foundation (see Fig. 18). The space between base portion and the edge of the foundation is filled with the cement to grout the poles or rods in place.

Title: Apparatus materializing the paths of electrified particles moving inside a magnetic field
IPC: G01R1/30
Filed: 1946-06-04
Abstract: 622,477. Electric tests. LOEB, J. M. June 4, 1946, No. 16992. Convention date, Nov. 14, 1945. [Class 37] [Also in Group XV] The path of an electrified particle in a magnetic field is determined by a wire 2 carrying direct current and subjected to a desired known tension. On the assumption that the wire has no stiffness or mass, the wire is stated to assume a configuration which is that T = Imv/e where T is the tension in the wire, I is the current in the wire, v is the speed of the particle, e is the charge carried by the particle and m is the mass of the particle at velocity v, so that m=m o /#1-v/c<SP>2</SP>, m 0  being the mass at rest and c being the velocity of light. The path may be photographed. When T is small, the magnetic field may be multiplied by N, giving T=Imv/eN. When the magnetic field is too large or too small, it may be divided or multiplied by a factor.
Patent GB-437683-A (GB)
Title: Improvement in pectin and its manufacture
IPC: C08L5/06
Filed: 1934-06-08
Abstract: Dried pectin is obtained by incorporating with liquid pectin obtained in any suitable manner an adherence retarding agent and then applying the mixture to a drying surface in the form of a relatively thin layer whereby a dry coherent film is formed which can readily be removed.  Suitable substances which act as adherence retarding agents include certain polyhydric alcohols, such as glycerine, and some derivatives; oils such as olive oil, lemon oil or animal oils such as cod liver oil; refined mineral oil or petroleum; waxes, paraffins and sugars.  The natural product from which the pectin is extracted may contain a sufficient amount of one or more of these bodies. Substances which are insoluble in or immiscible with the liquid pectin may be readily dispersed therein.  The pectin may be dried on a heated drum, disc, travelling metallic belt or other suitable smooth surface.  Preferably the liquid is applied to the surface of a drum and is fed into a trough extending across the face of the drum and formed by a portion of the cylindrical drying surface and a plate arranged at an angle.  A short distance in advance of the pool in the trough an adjustable bar is mounted across the surface of the drum to free the film from air bubbles.  The applied coating is preferably about 0,05 to 0,06 inches in thickness and is dried until the coherent film is about 10 per cent of the thickness of the applied coating.  It is then removed, e.g. by a flexible blade of stainless steel maintaining contact across the entire face of the drum.  For example, liquid pectin mixed with glycerine is dried in approximately 20 seconds at 214 DEG  F. and in 7,5 seconds at 225 DEG  F.  The temperature and duration of heating should be arranged to avoid deterioration of the pectin.  If desired, the adherence retarding agent together with other impurities may be removed by passing the pectin film through a solvent which will not affect the pectin itself, e.g. using glycerine, a solution of 95 per cent alcohol may be used for its removal.  Any solvent retained in the film can be removed by careful drying, e.g. in an air drier.  Furthermore, the film may be treated to control its hydrogen ion concentration by passage through a bath of weak alkali or acid.  The alkali or acid may be incorporated in the solvent bath employed to remove the adherence retarding agent, or in a subsequent bath.  For domestic jelly manufacture, the hydrogen ion concentration is adjusted to a pH of 3,55 to 2,0, and for commercial purposes, preferably above pH 3,55.  Excessive ash content of the pectin, due to alkali and alkaline earth salts of the pectin acids, may be removed by treatment in an acid bath, and the hydrogen ion concentration is also increased.

Convention date, July 13, 1932. [Class 70.] Rubber articles having a velvety or pilelike appearance are made by providing the surface with a multiplicity of intermingled areas of substantially different colours and light reflectivities disposed in chance or random arrangement and with a multiplicity of regularly disposed projections moulded thereinto during vulcanization. Preferably at least three colours are used, one of which may be the body stock, one being of high reflectivity such as white, bright yellow, &c., one of low reflectivity such as black, dark blue &c., and the other of intermediate reflectivity and of strong colour such as red, green &c. The area of each patch of colour is preferably small ranging up to a maximum of about one-half square inch. Surface irregularities other than those provided by the vulcanizing mould may be produced by using in the coloured portions, rubber having a different shrinkage and/or flow characteristic from that of the body stock, e.g., latex stocks applied to a body stock of masticated rubber. As shown, differently coloured portions of latex 11 and 12 are distributed on the surface of an article 10 of rubber which is then pressed in a mould to produce ribs 13. The differential flow or shrinkage of the applied stock produces further irregularities 14. In other figures, not shown, ribs of different shapes and a surface containing pyramidal projections, are shown. Specification 399,051 is referred to.

Filed: 1955-06-20
Abstract: 783,322. Speed governors. CATERPILLAR TRACTORCO. June 20, 1955 [April 26, 1955], No. 17732/55. Class 57. [Also in Group XXVII] A centrifugal governor 14 controlling the fuel supply of an internal-combustion engine having an engine driven supercharger is overridden at high load, low speed conditions by means 65, controlled by the inlet manifold pressure, to prevent the supply of excessive fuel. The governor 14 is controlled by a lever 39 through a servomotor 38 and actuates a lever 20 pivoted at 22 and provided with a pivotal end portion 24 connected to the pump control rod 28 by a link 26, the portion 24 being normally held against a stop portion 30 of the lever 20 by a spring 31 to transmit the movements of the lever 20. A stop-lever 65, controlled by a spring-loaded diaphragm 47 subject to inlet manifold pressure, is normally held out of the range of movement of the end 24 of lever 20 but when the engine speed drops at high load the inlet manifold pressure falls and the diaphragm 47 rises, moving the end of the lever 65 to contact the member 24 and limit the fuel supply to that required by the reduced air flow due to reduced supercharger speed. The resilient connection between the parts 24, 20 permits the normal movement of the governor to be unimpeded whilst the part 24 is held by the lever 25. As the engine speed rises and the intake manifold pressure increases, the lever 65 is rocked to the left to permit an increased fuel supply. The lever 65 carries a pin 61 which is engaged between flanges 56, 58 on a rod 55 and sleeve 51 screw-threaded together and secured to the diaphragm 47. The rod 55 is adjustable relative to the sleeve 51 to enable the lever 65 to be adjusted.
