Patent GB-920580-A (GB)
Title: Improvements in or relating to a method and apparatus for testing moulding material
IPC: B22C5/00
Filed: 1959-09-18
Abstract: 920,580. Testing physical qualities of materials. VEREIN ZUR FORDERUNG DER GIESSEREI-INDUSTRIE. Sept. 18, 1959 [Sept. 18, 1958; May 15, 1959], No. 31915/59. Class 106 (2). A method of testing a sample of a moulding sand consists in measuring the tensile strength of a test-piece after heating one end face so that a temperature gradient is produced in the interior of the test-piece, together with a layer of over-moistened sand. To perform the test, a cover 13 is placed on a tube 4 open at the other end and sand 12 rammed in. The tube 4 is then fitted over a piston 11 resting on a plate 6 which forms one of the end walls of a cylinder 3. A plunger 9 slides in this cylinder and is urged upwardly by a spring 8. A pin 14 is then passed through holes in the tube 4 and the plunger 9 and slots in the piston 11. The apparatus is placed in the position shown in broken lines and heated by means of a gas jet to 300‹ C. The apparatus is then moved to the position shown, and suction is applied through the pipe 10, pulling the plunger 9 downwards, thus lowering the tube 4, but not the test-piece 12, until the zone 29 is exposed. This zone is the area in which moisture which has evaporated during heating will have condensed. An upward pull is then given to the cover 13 by applying suction through a pipe 20. The cover 13 has an undercut portion of conical shape to grip the test-piece and the pressure in pipe 20 is reduced until the test-piece breaks apart. The pressure is indicated on a gauge 23. It is stated that the adhesion between the sand and the tube 14 is sufficient to prevent it sliding out of the tube. If this is not the case, the interior of the tube 4 can be slightly roughened or made conical. In another form, the cover 13 is provided with a number of undercut annular grooves.

Abstract: 659.582. Pneumatic tyres. VIGNINI, A. Dec. 13, 1949, No. 31919. Convention date, Dec. 22, 1948. [Class 144 (ii)] Means, operable whilst running, for inflating, checking, and adjusting the pressure in, pneumatic tyres comprises a supply of compressed air, a member mounted for rotation with the wheel and in valve-controlled communication with the tyre, and a co-operating non-rotary member forming the outer wall of a chamber which may be placed in communication with the supply of compressed air. Fig. 3 shows a general lay-out of the device comprising a compressed-air reservoir S, a 3-way cock R for controlling supply to a feed-pipe T leading, through automatically-operated valves V, V<SP>1</SP> and L, L<SP>1</SP>, to the tyres G, G<SP>1</SP>, or opening the pipe T to atmosphere through a port F, the pipe being fitted with a pressure-gauge M. As shown in Figs. 1 and 2, air is supplied through pipe 16 to a chamber 14 bounded by the wall 8 of the fixed element and a flexible diaphragm 12 sealed to a disc 11 which has a central aperture aligned with the axial bore of the rotary element carried by the wheel. The other end of the element is closed by a plug 3 connected by a pipe 15 to the automatic pressure-control valve device connected at 37 to the tyre-valve stem from which the needle has been removed. Communication between the. chamber 8 and the bore of the element 1 is normally shut-off by means of a spring-loaded ball-valve 20. If, however, the tyre-pressure falls below the predetermined limit, the valve 20 is forced from its seat and air passes from the chamber 14 to lift a spring-loaded valve in a sleeve 36 between the pipe 15 and the tyre. If the tyre-pressure becomes excessive, a spring-loaded vent-valve 33 is raised from its seat to open a port 32 to atmosphere. The loading-spring 34 is adjusted by means of a screw-cap 35.

Void [Abridged as open to inspection under Sect. 91 of the Acts, May 10, 1935]. [Class 138 (i)] An air-compressor 15 is connected to a sandinjector 17 in turn connected by a hose 18 to the top of a main water pipe 6 extending through the apartments of a house. The pipe at the bottom is connected by a hose 23 to a device 26 for reclaiming sand, comprising a container 27 in the upper part of which is an air outlet 28. Before the apparatus is in use the taps in the house are replaced by plugs. Hot air may be blown through the pipe 6 before the sand is forced through. If the pipe 6 is very much choked the sand is preferably sent through the pipe alternately in opposite directions. In extreme cases, the coupling 22 is undone, and flexible steel wire provided at one end with a hook or other enlargement is fed into the pipe with a twisting movement, while air pressure acts to remove the incrustation dislodged by the wire. Pulsating air pressure may be used. When the main pipe 6 has been cleaned branch pipes leading to the several apartments are treated in turn. The grinding-agent such as sand, quartz powder or slag powder may be conveyed under pressure by a gas other than air, or by steam or liquid.

IPC: G01N21/35
Filed: 1967-07-12
Abstract: 1,222,815. Infrared gas analysis. HILGER & WATTS Ltd. July 12, 1968 [July 12, 1967], No.32116/67. Heading G1A. In the quantitative analysis of a gas, the gas under analysis is passed into an enclosed space in which it is to be collected, this space having a volume greater than that required to contain the gas sample and also being partly made up by the measurement cell of an infrared analyser, and the output of the infrared analyser is monitored to indicate when the flow of sample gas into the space has been completed. The method is described with reference to the determination of the oxygen content of a metal sample. This is mounted in an induction furnace 2 on a graphite crucible, the furnace being purged by an inert gas, e.g. argon. Initially valve 8 is closed, a purging flow via needle valve 4 being maintained by valve 6 being open. The measurement cell 10 is evacuated by an exhaust pump 14. Then valves 6 and 12 are closed and 8 opened. The metal sample is now heated. Oxygen coming off combines with the carbon of the crucible to form carbon monoxide which is carried by the argon stream into cell 10. The absorption in the cell of radiation from infrared source 18 is measured by detector 16 whose output is continuously recorded on chart recorder 20. The latter records an increasing concentration of sample gas (carbon monoxide) until a steady value is reached when it is known that the extraction of oxygen from the metal sample has been completed. The needle valve 4 is set to give a continuing flow of carrier gas for a desired period. If the volume of sample gas is very large, part of the gas can be directed into a further chamber in series or parallel with the measurement cell 10. The method can be used in measuring the carbon content of steel, when carbon dioxide is produced by use of a stream of oxygen.
