Abstract: 1,034,682. Self-propelled missiles and propellants therefor. ATLANTIC RESEARCH CORPORATION. March 14, 1963, No. 10246/63. Heading F3A. A propellant charge 1, which may be used in the combustion chamber 2 of a rocket motor 3, has one or more metal tubes 8 extending longitudinally thereof from the forward end to the ignition surface 7, the tube or tubes serving to conduct fluid and so control the burning of the propellant by modifying the temperature of the tube and hence of the propellant in contact with the tube. The tube 8 has a maximum wall thickness of 0.015 inch and a maximum internal diameter of 0À15 inch. The propellant is inhibited from burning on the peripheral surface by a coating 5 and at the forward end by a plastic cement 6 bonding it to chamber wall 24. An opening 26 in wall 24 communicates through a manifold 12 with a reservoir 10 containing gas under high pressure and with a reservoir 15 containing liquid and having an electric heater element 19 embedded in the wall. Needle valves 13, 21 operated by remotely controlled actuators 14, 22 respectively shut-off the fluids from the tubes 8. Preferably the tube or tubes 8 extend slightly beyond the ignition surface 7 and to prevent heating of the tube at ignition, the tube and manifold may be filled with fluid 28, sealed by a disc 29 preferably made of material, such as an epoxy or phenolic resin, which ruptures under pressure or is volatilized by the combustion gases. If valve 21, Fig. 1, is opened, hot liquid is forced through the tube 8 by a piston 18, Fig. 3, driven by compressed gas 17. Alternatively, on opening valve 13, the tube 8 is cooled by the expansion of the gas 23 flowing from reservoir 10. A single reservoir may be used to store either a coolant or a heating medium. The igniting surface 34, Fig. 7, may be provided with conical recesses surrounding the ends of tubes 8. The propellant may be as in Specification 994,184, and the tubes of metals having a high conductivity such as copper, silver or aluminium, tungsten, platinum, magnesium, molybdenum and steel are also mentioned. The heating liquids preferably have a high boiling-point, e.g. paraffin oil, a polyglycol or esters such as dibutyl phthalate. Air or oxygen may be used as the gas.

Title: Improvements in and relating to traffic signals
IPC: G08G1/095
Filed: 1934-04-05
Abstract: 422,755. Road signals for controlling traffic. WEST, E. C., 306, Aldine Street, Rochester, New York, U.S.A. April 5, 1934, No. 10336. [Class 118 (ii)] In addition to the usual "stop" and "go" timed signals, selectively operable signals are provided to indicate the direction in which the traffic may proceed for filtering. In the construction shown in Figs. 1 and 2, the red signal 11 and green signal 12 are given by lamps 19 and 20 respectively under the control of switches 27, 32 operated by cams on the shaft 26. If filtering to the right is permissible during the stop period a lamp 21, in parallel with lamp 19 through a hand-set switch 35, illuminates an arrow 13 to indicate this movement. During the cautionary period in which switch 28 is closed, lamps 22, 221 and 23 only are in circuit (provided their control switches 37, 41, 42 are closed) and arrows 14, 15, 16 are consequently illuminated to show that traffic may proceed forward right and left. In a modified construction the two primary lamps only are used, these serving also to give the subsidiary indications, any unwanted signals 13-16 (Fig. 3) being obscured by hand-operated shutters 44-47. In a further modification (Fig. 4) the three arrows 14, 15, 16 in a compartmented casing supplementary to the existing signals, are illuminated by corresponding lamps controlled by a timing-shaft as in Fig. 2.

Title: Improvements in and relating to threads, filaments or yarn to be used preferably in the making of fabrics, and process of manufacture thereof
IPC: C08J5/02
Filed: 1935-04-04
Abstract: Rubber thread is made by incorporating an extensibility-reducing agent, such as glue, gelatine, casein, albumen, natural or synthetic resins, cellulose esters and ethers, sodium silicate, or sugar, with latex or with a coagulant, coagulating the latex and forming the coagulum into threads, and coating them with an adhesive, inextensible coating, such as glue, gelatine cellulose derivatives, starch, wax, resin, varnish. Attachment of the coating is thus improved and a stronger thread results.  Dyeing and vulcanizing may take place simultaneously with the treatment to restore extensibility, or dyes may be added to the latex or coagulant. Specifications 423,997; 440,256, 441,002, [both in Group IX]; 442,931, 442,935, 442,936, [all in Group V]; 447,972, 448,098, [both in Group IX], 449,314, and 449,462 are referred to.ALSO:Rubber thread is made by incorporating an extensibility-reducing agent, such as glue, gelatine, casein, albumen, natural or synthetic resins, cellulose esters and ethers, sodium silicate or sugar, with latex or with a coagulant, coagulating the latex and forming the coagulum into threads, and coating them with an adhesive, inextensible coating, such as glue, gelatine, cellulose derivatives, starch, wax, resin, varnish. Attachment of the coating is thus improved, and a stronger thread results.  Extensibility may be restored by dissolving out soluble additions and coatings, or these may be rendered insoluble, e.g. by treating gelatine with formaldehyde, alum, potassium dichromate or the like, to produce non-extensible and non-hygroscopic threads.  When the proportion of extensibility reducing agent and coating amounts to at least 50 per cent of the whole thread, a substitute for horsehair is produced.  According to an example, a 50 per cent glue solution is added to a compounded latex mix in proportions to yield 15 per cent of dry glue to 85 per cent of dry rubber.  This is extruded into a coagulating bath of acetone and acetic acid, and the thread is dried, and may be vulcanized.  Drying may be accelerated by passage through a bath of alcohol.  The thread is then coated by painting, spraying, dipping, or like methods, if desired, while stretched, e.g. by 20-25 per cent.  When a glue coating is applied, this may be plasticized by 3-25 per cent of glycerine. Cellulose acetate and like coatings may be applied to the thread while it is still tacky.  The threads may be woven into fabrics direct, or they may first be covered with silk, cotton, &c. windings.  Dyeing and vulcanizing may take place simultaneously with the treatment to restore extensibility, or dyes may be added to the latex or coagulant.  Specifications 423,997, 440,256, [Group IX], 441,002, 442,931, 442,935, 442,936, 447,972, 448,098, 449,314, and 449,462 are referred to.

Title: Multiple coupling for making pipe and hose connections
IPC: F16L37/42
Filed: 1971-04-21
Abstract: 1324446 Pipe or hose couplings CARL KURT WALTHER KG 21 April 1971 [24 April 1970] 10448/71 Heading F2G The male and female portions of a multiple pipe or hose coupling are locked together when locking balls 4, contained in radial bores in the female portion, are urged into an annular groove by an element in at least one coupling plug and sleeve arrangement which is axially movable by control means 9 on the external periphery of the coupling. In one embodiment, as shown, the radial bores, which are in a sleeve 2 rigidly held in the female portion, may be cylindrical, the locking balls 4 being of larger diameter than that of the axial bore 3 of the sleeve. In a preferred arrangement, the balls 4 are retained in radial bores (21) (Fig. 5, not shown), which are conical at their junction with the axial bore 3 and upset portions (23) (Figs. 4, 6, not shown) on the outside of sleeve 2 are peened over. Plates 14, 15 which are similar in both male and female portions, are clamped together by screws 16 against flanges 19, 6 on the spigots and sockets of individual couplings 20 and a locking sleeve 5 in the male part. The locking balls 4 are urged into an internal annular groove in the sleeve 5 by a leading portion 12 of the plug 1. The portion 12 trails the forward end of the sleeve 5, and the plug 1, which is slidably mounted in a control sleeve 9 and retained by a clip 13, compresses a spring 8 until the annular groove reaches the radial bores (21) (Fig. 5, not shown) whereupon the plug is snapped forward by the spring to force the balls into locked position. In decoupling, the sleeve 9; which has an easy-grip surface 10, is pulled back bringing the plug portion 12 clear of the balls 4 against the spring 8. The coupling may be generally cylindrical, as shown, having a polarizing pin 17 to ensure correct alignment; or of a rectangular formation with staggered rows of individual couplings and several plug and sleeve connectors (Fig. 3, not shown).

Title: Improvements relating to the roasting of sulphides
IPC: C22B1/10
Filed: 1960-03-24
Abstract: Sulphide material containing one or more of the metals nickel, cobalt and copper with or without iron is roasted in a bed in oxygen-containing gas at a temperature above the softening point of the sulphide material but below the melting point of the resulting calcine, the sulphide material being supplied to the bed in the form of granules or agglomerates and the oxygen-containing gas supplied at a rate sufficiently high to elutriate fine from the bed and to maintain the coarser granules or agglomerates in a fluidized condition.  The granules or agglomerates have a particle size not greater than 1.25 cm. Agglomerates may be bound with nickel sulphate solution, sulphuric acid or calcium lignosulphonate, and may contain fuel oil.  Fines removed from gases leaving the bed may partly be returned to the bed, and may be used in forming fresh agglomerates. To reduce sulphur in the calcine the roasting may be continued while the feed to the bed is interrupted at intervals.  Calcines containing nickel oxide that are to be reduced, may be activated after roasting by further oxidation at 675 DEG  to 790 DEG C.  The roasting may be performed at at least 110 DEG C. above the softening point of the sulphide material.  In examples, materials containing nickel, cobalt, copper, iron and sulphur are roasted in fluidized beds at 1085 DEG C., 1095 DEG C., 1040 DEG C. and 980 DEG C.
