Abstract: 631,634. Pouch-like containers. SHELLMAR PRODUCTS CORPORATION. Oct. 6, 1947, No. 26787. Convention date, June 27, 1940. [Class 133] A container in the form of a pouch is formed from laminated material, consisting of an inner layer 17 of thermoplastic rubber hydrochloride and an outer layer 18 of paper, metal foil or plastic material, the outer portions of each side of the pouch being folded inwardly at 15 and then outwardly at 16, the three bellows edges so formed then being thermally sealed. A web 10 of the laminated material is passed through a side-folding unit 14, cut into blank lengths by knives 21, and passed at increased speed by a conveyer 22 on to a platform 23 with a stop 24. A pivoted tucker blade 25 then folds an intermediate portion of the blank between pinch rollers 27, 28 and a conveyor 29 carries the blank into an intermittently operating edge-sealing machine 34, 35 with a stop 36. The pouch may then be filled and its mouth sealed as by means of heat and pressure.

[Class 36] [Also in Group XL] In a thermionic valve with a metal envelope, the electrode - supporting and lead wires are sealed through a one-piece glass disc which is sealed directly to the inner wall of the metal body. The wires are sealed through the disc at the vertices of a polygon, the greatest diagonal of which is more than 60 per cent of the greatest internal diameter of the valve; this polygon is preferably a cyclic polygon, the vertices of which correspond to the positions of the valve contact pins. In the arrangement shown, the body 9a of the valve is made of soft iron to which is hard soldered a slightly conical ring 9b of iron chromium alloy suitable for sealing to glass. A glass disc 1, just too large to fit into the ring 9b when cold, supports eight leads for a five grid valve, and a central exhaust tube 2. In manufacture, the disc 1 is uniformly heated to a temperature somewhat below the softening of the glass and the body is heated so that the ring 96 is red-hot and is pressed on to it. The edges of the ring may be turned over on to the disc 1.

Abstract: 764,474. Aircraft arrester and catapult gear. ZELM, W. D. VAN. Oct. 29, 1952, No. 27247/52. Class 4. Arresting gear for aircraft comprises an arresting engine which includes a plurality of metallic spring drums and spring ribbons leading therefrom, brake means for resisting the unwinding movement of said drums, and means for varying the pressure of said brake means. Arresting cables 10, 12 mounted on pulleys are connected to a sheave assembly 40 which is slidably mounted for movement in the direction of cable movement. The casing of the sheave 40 has a plurality of connections for the free ends of spring strips 50 arranged in equal numbers on opposite sides of the sheave pivot pin 38 and formed at their other ends into spring coils 52, the resilience of the coils being such that after the cable assembly has been extended by a landing aircraft, it can be automatically restored to its original position. To regulate the rate of retardation and to prevent premature shortening of the cable assembly before the aircraft arrestor hook has been uncoupled a braking mechanism 54 is provided. The strips 50 pass freely through the casing 58 of the mechanism 54 and they are inter-leaved with friction pads or shoes 64 backed by opposed end plates 70 and separated by opposed pistons 62 operating in cylinders 60. A cavity 80 between the pistons is supplied with pressure liquid and a hydraulic system is described in which the degree of braking is varied partly automatically and partly manually. To dissipate heat generated in the strips 50 by the braking action a liquid cooling device 56 is provided. Disc brakes driven from shafts secured to the coils 52 may be used in place of the mechanism described. The term " aircraft " includes catapults, to the movable parts of which the arresting gear may be applied. Specifications 575,707, 582,237, 595,306, [all in Group XXII], and U.S.A.

Filed: 1952-10-30
Abstract: <PICT:0708800/IV (a)/1> In the manufacture of tubular films from a normally crystalline vinylidene chloride polymer or copolymer thereof by extruding the molten polymer in tubular form from a die 10 downwardly into a cooling bath 12 in which the tube is supercooled, constricted by rolls 13 and filled with a lubricating liquid 14 to a level near that of the bath, whereafter the film is stretched and oriented by inflation with air between the pairs of pinch rolls 16 and 17, the tendency of the opposed internal faces of the flattened tube to adhere to each other is obviated by introducing, continuously and at a uniform rate, a finely-divided solid anti-sticking agent suspended in a gas stream, e.g., air, into the space between the die and the surface of the lubricating liquid in the hot tube while venting continuously the suspending agent.  As shown, the gaseous suspension is introduced through tube 21 and the gas vented through tube 20.  A baffle plate 22 deflects the powdered solid against the internal walls of the nearly molten tubular film.  Specified anti-sticking agents are finely ground polyvinylidene chloride, micropulverised mica or starch, zinc stearate and talc. Specifications 656,735 and 664,638 are referred to.

Title: Homogeneous fuel elements for nuclear fission reactors
IPC: G21C3/06
Filed: 1957-08-30
Abstract: 821,297. Nuclear reactors. DEUTSCHE GOLD UND SILBER SCHEIDEANSTALT VORM ROESSLER. Aug. 30, 1957. No. 27416/57. Class 39(4). A shaped element serving as a fuel element in a nuclear reactor comprises a pratically homogeneous mixture of a fissile material which may include fertile material or compound and a filler, which is preferably a moderator material, wherein the fissile or fertile material is in the form of particles the largest dimension of which is smaller than the range of the fission products. The fissile material is preferably in the form of particles of a size between 5 and 12 Á and may be mixed with graphite. With this arrangement solid fission products tend to accumulate in the graphite, and the gaseous fission products are removed by the reactor coolant. Fission products may then be largely removed from spent fuel by a comminution process followed by a separation of the graphite from the fissile material by screening, air-sifting or sedimentation. The fuel elements may be arranged in a porous abrasion-resisting non-metallic casing, for example of graphite or beryllium oxide or, in the case of fast reactors, of barium oxide or barium silicide. In one example, uranium carbide of a grain size between 5 and 10 Á is mixed with ultra-fine graphite in the ratio of 450 atoms of carbon at one molecule of uranium carbide, mixed with an organic binder, and the mixture extruded as cylinders with a diameter of about 25 mm. and a height of 50 mm. After drying and heating to 650‹C. the elements have a sufficient mechanical strength and a porosity of about 25%; they are placed in a casing of porous graphite to form a fuel element.

IPC: B60T13/74
Filed: 1921-10-18
Abstract: 191,826. English Electric Co., Ltd., and Andrews, H. H. Oct. 18, 1921. Electric and magnetic.-Electric current for actuating track brakes is supplied by generators driven by the wheels of the vehicles, and is kept approximately constant by an automatic regulator acting to vary resistance in both the field and the armature circuit of the generator. The invention is described in connection with an electrically propelled vehicle, in which a driving motor 1 is utilized as a braking-generator. The regulator 27 shown in developed form in the Figure, is actuated against a spring 7 by a solenoid 20 in series with the motor armature 1 and the brake magnet 6. Increase of current moves the regulator contacts 26 to the left, increasing the armature resistance 5, and diminishing resistance 3 in parallel with the field 2. A safety-resistance 8 controlled by additional contacts 16 on the regulator 27 is inserted in the braking circuit automatically in case the transition is made when the motors are running at high speed. A solenoid 13 opposing the solenoid 20 may be switched in when greater braking current is required for emergencies. The whole arrangement is controlled by two additional contacts A, B on the master controller C and an electromagnetic braking switch D.
