Title: Method of bonding particles into unitary bodies
Inventor: PARKER JOHN CASTLEREAGH
IPC: B22F3/14
Filed: 1969-07-18
Abstract: 1,243,706. Pulsed heating in compression moulding. J. C. PARKER. 18 July, 1969 [19 July, 1968], No. 36264/69. Heading B5A. [Also in Divisions B3 and C7] Weldable particles such as metals, oxides or metallized ceramics are bonded together by applying pulsed electrical energy of at least 1,000,000 amps/sq. inch for about a millisecond, to the compacted particles. Compaction is effected by a controlled pressure pulse or pulses in synchronism with the pulsed electrical energy. As shown in Fig. 2, pressure platens 12 and 13 also apply the pulsed electrical energy to the powder 11 in die 16. The powder is initially compacted by lower platen 13, e.g. at 3000 p.s.i. A pulsed pressure with a peak value of 20,000 p.s.i. is superimposed on the compact by means of pressure transformer 18 operated by power switch 26. The process controller 25 times the electronic switch 24 to pass pulsed electrical energy to the compact via 23 and 21 as a step function approx. 90 degrees or 4À1 milliseconds after the initiation of the pressure. The powders, e.g. Fe, Ti may be mixed with glass or boron fibres or filaments. Wire mesh may be used as reinforcement and the powders may be bonded to sheets, skins or membranes, e.g. stainless steel or Ti 14, 15 in Fig. 2. The atmosphere during pressing may be a vacuum, inert, carburizing or decarburizing. The pressure pulses may be supplied by hydraulic actuators or detonating devices in place of the pressure transformer. Continuous lengths of sintered material may be formed by pressing together previously bonded compacts.

Filed: 1973-07-31
Abstract: 1387778 Liquid trap VIRGINIA CHEMICALS INC 31 July 1973 36363/73 Heading BIT [Also in Division F4] A trap 10, whereby liquid refrigerant and oil passing from the evaporator 22 are separated from refrigerant vapour upstream of the compressor 24 in a refrigeration circuit, comprises a chamber having an inlet 18 and an outlet 20. The entering gas disperses across the diameter of the chamber causing the majority of entrained liquid droplets to impinge on the walls and run down to the bottom or to fall to the bottom. The vapour passes to the outlet 20 through a J-shaped tube, the inlet end of which is spaced from the inlet 18 and is aligned therewith. A small aperture is provided in the side wall of the bottom portion of the J-tube and venting apertures are provided at the connection of the J-tube with the outlet 20 whereby liquid accumulated at the bottom of the J-tube during shut-down is prevented from passing through the outlet as a slug on re-start.

Abstract: 971,393. Vehicle controls. FORD MOTOR CO. Ltd. Sept. 24, 1963 [Sept. 25, 1962], No. 36429/62. Heading B7H. [Also in Division F1] In an I.C. engine hydraulic throttle control arrangement a master unit is connected to a personally operable member 1 and a slave unit 15 is connected to a throttle spindle 19 through a spring element 18. When pedal 1 is depressed rod 6 moves diaphragm 11 through plunger 12 thus reducing the volume of chamber 9 and causing a liquid flow to increase the volume of chamber 15 to drive the piston rod and clevis 16 to the right. Torsion spring end 18a tends to move away from an abutment 23 on throttle lever 22 but the other spring end 18b maintains the contact so that lever 22 and spindle 19 are rotated counter clockwise in dependence upon the movement of pedal 1. At full throttle position any subsequent movement causes the spring to distort and end 18a to move away from the abutment 23. The canister 3 may be varied in shape to change the relationship between the throttle spring movement and the pedal movement.

Title: Improvements in the treatment of fabrics or yarns composed of natural celluloses
IPC: D06M11/56
Filed: 1928-12-12
Abstract: 323,345. Marshall, W. Dec. 12, 1928. Yarns, treating with liquids; yarns, mercerizing. -In mercerizing and similar processes wherein yarns composed of natural celluloses such as cotton, flax, &c. are treated with caustic soda or potash, without the presence of carbon disulphide, there is added to the washing water for the removal of the caustic alkali one or more of the following protecting-agents :-sodium or potassium chloride, sulphate, nitrate, or chlorate, sodium thiosulphate, sucrose, glycerine, or glucose. The addition of the protecting-agent imparts improved softness and lustre to the goods, while the risk of damage on light and fine goods is minimized since there is less contraction during the washing process. The washing may be effected with or without tension and at temperatures up to or above 212‹ F. According to the Provisional Specification, ammonium chloride and sulphate may be used as protecting-agents.

Abstract: 899,239. Direct lift in jet propelled aircraft. GENERAL ELECTRIC CO. Oct. 28, 1960 [Nov. 2, 1959], No. 37129/60. Class 4. Means for diverting gaseous flow out of a passage or duct having a nozzle in or through an aircraft part, through which passage or duct and nozzle low pressure gas is impelled, comprises a source of high pressure gas arranged to discharge through slot means located adjacent the nozzle and on that side of the passage or duct towards which the low pressure gas is to be diverted. The Figure shows an aircraft fuselage having a duct 11 ending in a nozzle 13, out of which air is discharged in the direction of arrow 19 by a turbo-fan engine 14. To obtain direct lift, e.g. for vertical take-off, a valve 21 is opened to connect a chamber 16 to a source of fluid under pressure, which is discharged through a slot nozzle 17 in the direction of arrow 18, and induces the relatively low pressure discharge from nozzle 13 to follow arrow 20. The same arrangement may be embodied in a wing, the nozzles extending spanwise as far as possible. The upper surface of nozzle 13 may be an adjustable and extendable flap, Fig. 4 (not shown), or a jet of gas may be used as the equivalent of such a flap.

Title: Process for the manufacture of o-aryl-phosphorodichloridothioates
Inventor: TOLKMITH HENRY
IPC: C07F9/20
Filed: 1959-11-05
Abstract: A phosphorodichloridothioate having the formula R.O.P(S)Cl2 wherein R is phenyl or substituted phenyl is obtained by reacting sulphur at elevated temperature with a phosphorodichloridite of the formula R.O.P.Cl2 the reaction being carried out in the presence of phosphorus trichloride which is applied in a proportion at least high enough to chemically bind substantially all unreacted sulphur remaining after completion of the reaction.  The substituted phenyl radical may suitably be a mono-or poly-chloro- (or bromo)-phenyl, or 2-chloro (or bromo)-4-lower (C1-C4) alkyl phenyl. Increased yields can be obtained if an amount of the desired phosphorodichloridothioate product is initially added to the reaction mixture, preferably from 0.25 to 1.5 mole being added for each mole of the dichlorodite contained in the reaction mixture.  The reaction temperature is preferably from 160 DEG C. to 180 DEG C. and atmospheric or elevated pressure may be used.  The amount of sulphur added is advantageously at least 1 gram atom for each gram mol. of the phosphorodichloridite employed but less than one gram atom of sulphur should be used for each molecular proportion of total phosphorodichloridite and phosphorus trichloride employed.  Also, the amount of phosphorus trichloride employed should generally not exceed 0.8 molecular proportion for each molecular proportion of phosphorodichloridite employed.  In some cases part of the sulphur may be replaced by its molar equivalent of phosphorus thiochloride with a corresponding reduction in the amount of PC13 used.  Examples are given for the production of compounds of the first given formula in which R is 2,4,5-trichlorophenyl and 0-(2- chloro-4-tertiarybutyl) phenyl and other specified products obtainable by the process are those in which R in the formula is 2-bromophenyl, 2, 4-dichlorophenyl, 2,4-dibromophenyl, 2,5-dichloro (or dibromo) phenyl, 2,6-dichlorophenyl, 2-chloro-4-methylphenyl, 2-bromo-4-ethylphenyl, and 2-chloro-4-isopropyl phenyl.  The O-halophenyl- and O-(2-halo-4-lower (C1-C4) alkyl) phenyl-phosphorodichloridites used as starting materials may be obtained by reacting phosphorus trichloride with the corresponding substituted phenol in the presence of magnesium chloride as catalyst, the reactants being mixed together and heated at the boiling temperature.  At least 7 moles of PC13 are employed for each mole of the phenol.
