Title: Improvements in and relating to the manufacture of particulate expandable polymers and to the manufacture of expanded polymers therefrom
Inventor: MUIRHEAD LESLIE ALFRED
IPC: B29C48/05
Filed: 1965-03-17
Abstract: Expandable particles of a thermoplastic organic polymer are prepared by incorporating a vaporizable expanding agent in a heat-plastified mass of the polymer, extruding the polymer in filamentary form into an essentially gaseous environment at atmospheric or substantially atmospheric pressure and immediately cooling the extruded polymer by contact with a fluid at 60 DEG  to 80 DEG C. under conditions such that the temperature of the extruded polymer does not fall below 60 DEG  C. maintaining the temperature of the extruded polymer between 60 DEG  and 80 DEG  C. during a normalizing period immediately following extrusion and before and/or after cutting the extruded polymer into particles and cooling them to ambient temperature.  By normalizing period is meant the minimum time for which an extruded polymer in filamentary or particulate form must be maintained at a temperature of 60-80 DEG  C. and at normal pressure in order that at least 90% of the cells of the particle, if it were completely expanded, would be not greater than 100 microns in diameter.  The extruded polymer may be face-cut into particles whilst being simultaneously cooled to a temperature between 60 DEG  and 80 DEG  C. by droplets of a liquid sprayed against the face of the die-head, and the resulting particles immediately contacted with a body of said liquid at 60 DEG -80 DEG  C.  Alternatively, the polymer may be extruded into a body of liquid at 60 DEG -80 DEG  C. from a die-head located adjacent to but spaced from the liquid, the resulting filamentary extruded polymer being removed from the liquid for cutting into particles which are immediately contacted with a body of liquid at 60-80 DEG  C.  The preferred thermoplastic organic polymer is polystyrene. The preferred expanding agent is n-pentane or iso-pentane or a mixture thereof.  A suitable liquid is water. The major part of the normalization may be carried out in a tower containing water at 60 DEG -80 DEG  C., a suspension of polymer particles in water at 60 DEG -80 DEG  C. being supplied continuously to the base of the tower and moved progressively up the tower for discharge from the top.  The normalized particles are then transferred on a perforated conveyer belt to a storage bin, any water draining from them and being heated and re-used in the process.  An air dryer may be used to help drying.

Filed: 1934-04-16
Abstract: 424,737. Treating charge. PALLANT, W. C., Crownthorpe, Rotherfield Greys, Henleyon-Thames, and IVEY, D. P., 15, Victoria Road, Brighton, Sussex. April 16, 1934, No. 11418. [Class 7 (ii)] [See also Group XXXIV] A mixture of lubricant and air is injected into the induction pipe of an internal -combustion engine by means of a pulsator actuated by the making and breaking of a connection with the vacuum in the induction pipe. The apparatus comprises a piston 5 working in a cylinder 3 mounted in a lubricant container 1 ; lubricant passes from the container 1 to the cylinder 3 through port 8 controlled by a valve 9 carried by the piston ; a port 13 communicates with the air above the lubricant level in the container 1. The suction in the induction pipe causes the piston to move upwards, opening the ports 8, 13 ; the mixture of lubricant and air is byepassed by passage 11 to the suction side of the piston, thereby breaking the vacuum, so that the piston returns to its lowest position, and repeats the operation. The piston is provided between its ends with a filter 19 impregnated with decarbonizing fluid, which passes by ports 15, 17 and passage 16 into the pipe 4 connected with the induction pipe.

Title: Improvements relating to pressure sensitive control devices for aero-engines
IPC: G01L11/00
Filed: 1942-08-14
Abstract: 587,565. Controlling aero-engines. POWER JETS, Ltd., and WALKER, D. N. Aug. 14, 1942, No. 11444. [Class 7 (vi)] A control system for a gas turbine or other aero engine comprises a separate air compressor of predetermined or controllably variable compression ratio driven by the engine and a pressure responsive device acted upon by the air pressure generated by the compressor and in its response thereto controlling the engine, with or without the co-operation of a manual control. The compression of a pump comprising a cylinder 20, Fig. 2, and piston 21 is controlled by, a plunger 29 adjusted by a cam 29B against the pressure of a spring 29A and the discharge pressure acts on a ram 25, displacement of the ram causing a cam 25A to vary the tension of a spring 27 which loads a fuel relief valve 28 and thus determines the pressure of the fuel supply and speed of the',engine. The cam 25A may compress' or ease the spring 27 through a lever the opposite end of which is positioned by a cam which replaces the cam 29B, the plunger 29 being fixed. As shown in Fig. 4, the pump has a pre-determined compression ratio and comprises a piston 43 and cylinder 41, the compression chamber of which communicates through a passage 42A with a cylinder 42 open to the atmosphere at its upper end. A piston 45 on the cylinder 42 is actuated by the crankpin 43C of the pump piston 43 through a link 44 the outer end of which is manually adjustable to, vary the stroke of the piston 45 and the time when it closes ports leading from the passage 42A into the cylinder 42. The outlet of the pump is connected to a pipe 50A, Fig. 5, communicating with the upper side of a diaphragm 56 loaded by a spring 57. A plunger 53 operatively connects the diaphragm 56 to a relief valve 51 on the fuel supply line 5, the pressure at which the valve lifts determining the speed of the engine. A reservoir between the pump and the relief valve may prevent unduly rapid changes in the fuel supply, especially at low speeds. As the pump operates at a definite compression ratio the discharge pressure varies with the atmospheric pressure and compensates for altitude changes.

Title: Improvements in or relating to photogravure plate printing presses
IPC: B41F9/06
Filed: 1935-04-15
Abstract: 436,638. Printing-machines. MAILANDER, W., 68, Hallstrasse, Bad Cannstadt, Stuttgart, Germany. April 15, 1935, No. 11615. [Class 100 (ii)] Inking-apparatus.-In an inking-apparatus for a rotary intaglio printing-machine of the kind in which an immersed roller 1 is arranged just out of contact with the printing-surface 6 which is separated by a film of ink from the roller 1, the supply of ink to the roller 1 is controlled by means operated by the machine in such a way that the film is used up just as the last portion of the printing-surface passes the roller 1. This may be effected by a scraper 13 or a roller which is normally kept raised from the roller 1 by means of an adjustable cam 22, a lever 23, and a link 25 having an adjustable connection with a lever arm 26 on the shaft of a cam 27 adapted to act on a roller 28 of a lever arm 29 on the shaft 17 carrying the holder 16 of the scraper 13. The shaft 17 is mounted in lever arms 4. The cam 22 and the adjustable connection 30, 31, 32 are set so as to cause the scraper 13 to descend and cut off or restrict the flow of ink so as to cause the film of ink to be used up when the end of the printing-plate passes the roller 1. A screw 21 engaging a stop 20 on the holder 16 limits the inward position of the scraper 13. The roller 1 is mounted in levers 4 pivoted about a shaft 7 and pressed by springs 19 into contact with a hand-operated cam 8 which can be set so as to move the roller 1 out of contact with the printing surface. The cam 8 contacts with a screw 11 which enables the thickness of the ink film to be adjusted. The scraper 13 is arranged in such manner that it does not obscure the visibility of the inking- zone 12, and is downwardly inclined in an outward direction and co-operates with a gutter 15 to guide excess ink back to the trough 2. Instead of controlling the supply of ink to the plate by means of scraper devices, the feed roller 1 may be driven by variable gearing which causes the roller to be slowed down or stopped before the plate passes off the roller and the accumulation of ink is thus used up.

Title: Improvements in and relating to the manufacture of metallic alloys and to articles made therefrom
IPC: C22C27/04
Filed: 1931-04-21
Abstract: Alloys, particularly suitable for making cutting tools, contain 20-35 per cent of cobalt, 15-30 per cent of tungsten, or molybdenum, or both tungsten and molybdenum, 0,5-3 per cent of vanadium, and 0,2-0,6 per cent of manganese, the balance being iron.  Carbon and chromium are regarded as impurities and should be kept as low as possible.  In an example, in making a lathe cutting tool, the alloy is prepared by melting in a furnace free from carbon, and casting.  The ingot is reheated, worked, and annealed to render it machinable.  A further heat treatment at 1000-1400 DEG  C. followed by quick cooling renders the alloy tough, in which condition it may be light machined to the desired shape. The toughened tool may then be hardened by heating it wholly or locally to 250-650 DEG  C. and cooling quickly.  In the Provisional Specification the manganese content of the alloys is stated to be up to 0,8 per cent.  Reference has been directed by the Comptroller to Specifications 373,690 and 385,934.
