Abstract: 468,161. Paper containers. JAGENBERG-WERKE AKT.-GES. Aug. 27, 1936, No. 23538. Convention date, Oct. 23, 1935. [Classes 18 and 125 (iii)] A paper container, e.g. of cup or bottle shape, in which a closing cap 6, Fig. 2, has a screw thread which engages an inner screw thread 2, Fig. 1, on the container is provided with an upper rim x which joins the screw thread on the container and may be more conical than the thread. The cap may be conical or cylindrical. The pitch of the two threads may differ slightly to give a tight joint. The flanged rim of the cap may contact the rim of the container which may itself be flanged. The continuous screw threads on the cap and container may be replaced by interrupted threads, grooves or the like so that the closure resembles a bayonetjoint.

Title: Device for discharging rockets from aircraft
IPC: F41F3/065
Filed: 1948-09-07
Abstract: 649,480. Discharging rockets from aircraft. AKTIEBOLAGET BOFORS. Sept. 7, 1948, No. 23554. Convention date, Nov. 7, 1947. [Class 9 (ii)] A device for discharging rockets comprises a container 1 fitted with discharge tubes 2 each housing a rocket, the container being of cylindrical form and provided with a detachable streamlined nose-piece. The tubes are rigidly fixed in the casing and to each other. At the forward end the container or casing is closed by a nosepiece made in two halves 3, 4 having loops 5 engaging hooks 6 on the casing, the halves being held together by brackets 7, 8 connected by a cylinder 9. The cylinder contains an explosive charge 12, e.g. black powder and is closed by cap-pieces 10, 11. One cap-piece 10 accommodates an electric igniter 13, while the other piece is secured by a weak pin 14. The rear of the container is closed by a torpedo-shaped cap 15 having a loose tip 16. The container is secured to an aeroplane by vertical stays 17, 18 connected by stays 19, 20. The rockets are discharged by closing the circuit to the igniter 13 in the cylinder 9, thereby forcing off the endpiece 3, 4 and closing the circuit to discharge the rockets. The rockets are discharged in groups, the grouping being arranged to cause the minimum disturbance to adjacent rockets. The first rocket discharged blows off the tip 16 and subsequently the cap 15 bursts. The rear stay 18, Fig. 4, contains a charge 21 and an electric igniter 22, the stay being weakened by a groove 23, so that on firing the igniter 22 the stay fractures. When all the rockets have been discharged the circuit to the igniter 22 is closed, the charge 21 fired and the stay 18 fractured, whereupon the stay 17 becomes detached and the whole casing falls away from the aircraft. A safety device may be provided so that the circuit to the igniter 13 will not close until the two halves of the nose-piece have been closed together and an insulating member withdrawn.

The extraction may be batchwise or continuous using a countercurrent extraction process.  The solubility parameter d  is derived as in "Solubility of Non-electrolytes" by Hildebrand and Scott, 3rd Edition, 1950, pp. 435-9.  Suitable solvents include toluene, hexane, heptane, octane, cyclohexane, cyclohexene, ethylcyclohexane, carbon tetrachloride. Solvents suitable in admixture with others to produce the desired properties include benzene, xylene, chlorobenzene, chloroform, ethylene dichloride, perchloroethylene, methylene chloride.ALSO:A glycol monoester of formula <FORM:1036163/C3/1> where x is 2, 3 or 4, and R is H, CH3 or C2H5, is purified from small amounts of the diester by solvent extraction (see Division C2) and a 10 ml. sample of the aqueous esters is mixed with 5 ml. ethyl alcohol, 0.5 ml. of 2% aqueous thiourea and 0.2 ml. of 35% hydrogen peroxide and allowed to polymerize.  The polymer produced is a viscous alcohol-soluble liquid if all diester is removed, indicating no cross-linking, or is stringy, partially alcohol-soluble if only part of the diester is removed.

Title: Valves for airships, balloons and the like

Filed: 1928-08-21
Abstract: 296,702. Wasser-und Luft-Fahrzeug- Ges., (Assignees of Luftfahrzeug-Ges.). Sept. 5, 1927, [Convention date]. Aerostats.-A valve for airships, balloons, &c. has its movable member provided on the side remote from the gas space with a readily collapsable chamber in communication with a space not subject to accidental variations of pressure. Fig. 1 shows a free balloon having a central gas discharge trunk a in which is arranged an annular bag b‹ having its inner wall secured to suspended rings e and its outer wall normally resting against slots a<1> in the trunk a communicating with the gas chamber. The bag b<0> communicates by a pipe d with the atmosphere away from the trunk a, or in some cases the bag may be merely left open at its lower end. Fig. 3 shows a modification for airships in which the chamber b‹ is formed by a bellows i connected to the spring loaded valve disc h and to a rigid frame k. A pipe d puts the chamber in communication with tha space o between the gas bags and the envelope. A similar valve for a captive balloon has its chamber connected to the air ballonet and is provided also with manual means for opening it. The Specification as open to inspection under Sect. 91 (3) (a) comprise also the following subject-matter. Fig. 6 (Cancelled) shows a valve for controlling the height of a free balloon. The chamber b<0> is suspended from bows k and has a disc v connected to the flexible wall of the chamber. A tube w connects the disc v to the valve disc h which is normally held closed by a spring z. An auxiliary valve x is initially held open by a weight y to put the chamber b‹ into communication with the gas space. When the weight y is removed to close the valve x the gas expands in the chamber b‹ as the balloon rises and opens the valve h. If the valve x is designed not to close completely, the valve h quickly shuts again and the altitude of a free balloon can thus be stabilized. This subject-matter does not appear in the Specification as accepted.

Abstract: <PICT:0461991/III/1> In an apparatus for drying sludge, cement slurry, and similar substances, hot gases are passed through a layer 4 of the material to be dried which is carried by an endless chain which forms a sliding heap or layer on an inclined grate 5, fresh parts of the chain being continuously added to the top of the sliding heap and parts being removed at the bottom.  The chain dips into and picks up the substance in the supply tank 2.  It enters the drying chamber through a channel 11 which it blocks in order to prevent escape of gases past the chain.  Hot gases from a kiln are admitted through opening 6 and are caused to pass several times through the layer of slurry by partitions 1 and 7.  Dried material accumulating at the bottom of the chamber is delivered into the kiln by a screw-conveyer 8.

Abstract: 469,701. Relief valves. EVANS APPLIANCE CO. Sept. 4, 1936, No. 24230. Convention date, Oct. 26, 1935. [Class 135] [Also in Groups XXVI and XXVIII] A fluid pump 15 is provided with a byepass valve 38 which is opened by fluid under excess pressure on the delivery side 24 by way of a chamber 60, which overcomes the pressure of a spring 52: An adjusting nut 46 for the spring is prevented from rotating by a ball 48 which is pressed into a cavity on the nut. Fluctuations in pressure in the suction chamber 55 do not affect the valve 38, owing to the area of the valve and the mean area of the sylphon bellows 41 being about equal. A piston 66 has a small hole 69 to allow fluid under pressure to pass within a cylinder 67 which combined with the effect of a spring 73, dampens vibrations of the valve stem 65 and valve 38. The parts in the suction and delivery chambers 55, 60 may be interchanged. Baffles may be provided in the ports 55, 61 to be cut away in part for calibration purposes. The housing 15 may be of aluminium and the liner 18 of cast iron.
