Title: Ejection gun for aircraft ejection seat
IPC: B64D25/10
Filed: 1956-10-12
Abstract: 800,898. Aircraft ejection seat guns. SVENSKA AEROPLAN A.B. Oct. 12, 1956 [Oct. 13, 1955], No. 31170/56. Class 4. [Also in Group XXI] An aircraft ejection seat gun comprises two telescoped members, one attached to the aircraft and the other to the seat, the members being adapted to be forced apart on detonation of an explosive charge by a hammer which before reaching the firing position frees locking means normally holding the members telescoped. In Fig. 5, an outer cylinder 121 is anchored to the aircraft structure 16 through a part spherical base 15 and washer 21 retained by a nut 20, mating with a part spherical portion 17 of the structure 16, thus allowing limited universal movement for alignment purposes. An inner cylinder 13<SP>1</SP> containing an explosive charge (not shown) and a detonator 41, is closed at the top by a cover member 36<SP>1</SP> forming a housing 39 for the firing mechanism closed by a plate 24. The cylinder 13<SP>1</SP> is secured to the seat (not shown). The firing mechanism comprises a tubular member 49 flanged at 45 and slidable in the plate 24, being urged downwards by a spring 46 but normally held cocked by a latch 51 engaging a flange 50. The hammer comprises a disc 42, a pin 44 and a tubular stem 79 slidable in the member 49. The disc is normally held in contact with flange 48 by a spring 82. Balls 73 are located in ports 74<SP>1</SP> in cylinder 13<SP>1</SP>, and are normally held in engagement with a groove 75<SP>1</SP> in cylinder 12<SP>1</SP> by the periphery of disc 42, whereby the cylinders are held telescoped. The latch 51 is integral with an arm 52 pivoted to the plate 24 at 53 and operable by the pilot by a flexible cable. When the latch is released, spring 46 drives the hammer down to explode the charge. The balls 73 are then retained by deformable flanges 87<SP>1</SP> on disc 42, so that when the charge explodes, the groove 75<SP>1</SP> forces the balls inwardly and the cylinders separate. In the event of a misfire, the balls hold the cylinders telescoped. The cylinders can be manually separated without detonation by depressing a head 80 on the hammer and compressing spring 82, thus separating the hammer from flange 48 and freeing the balls 73. The latch 51 and arm 52 are held in the cocked position by a ball 65 in a bore 66 formed in a boss 64 on plate 24, the ball engaging a recess 68 in an extension 69 of arm 51. The ball is retained in position by a pin 62 secured by a weak shear pin 71, whereby the firing mechanism cannot be actuated until pin 62 is manually withdrawn. A third cylinder attached to and moving with cylinder 13<SP>1</SP> may surround cylinder 12<SP>1</SP>, being telescopically sealed thereto.

Patent GB-906066-A (GB)
Title: Ribbons for lubricating and sealing threaded joints
IPC: F16L15/04
Filed: 1959-09-14
Abstract: A lubricating and sealing ribbon for a threaded joint comprising mating male and female threaded fittings, e.g. a pipe joint, is made by mixing polytetrafluoroethylene powder with an extrusion aid, e.g. naphtha or white oil, and extruding into a strip which is then rolled to the desired thickness and passed through a heating device at a temperature high enough to evaporate the extrusion aid but not to cause sintering.  During the extrusion process, the polytetrafluoroethylene particles are elongated so as to become fibril-like in structure and oriented in cohering side-by-side relation to one another.  Even though the elongated particles cohere sufficiently for the ribbon to be stretched over the male threaded fitting, they are not coalesced as they would be in a sintered polytetrafluoroethylene film and the ribbon is thus compressible and readily conformable to the shape of the threads.  After having the ribbon wound around it, the male fitting is threaded into the female fitting to form the sealed joint.  The ribbon is of at least 1mm. thickness and of a specific gravity between 1,2 and 1,8.

Title: Improvements in or relating to microphones
Inventor: PONTZEN GEORGE RAOUL
IPC: H04R3/00
Filed: 1958-10-01
Abstract: 859,031. Microphones. LUSTRAPHONE Ltd. Sept. 29, 1959 [Oct. 1, 1958], No. 31346/58. Class 40 (4). A microphone head 5 has two microphones 7, 8 and is connected to four output wires 22- 25 (contained in a cable 21) by means of a switch unit 4 incorporating two switches 26, 27 ; in one position of switch 26 the output of microphone 7 is applied to wires 22 and 23 and the output of microphone 8 is applied to the other two wires 24 and 25, whilst in another position of switch 26 the two microphones are connected together in series to two of the wires (22 and 25), switch 27 serving for reversing the connections of microphone 7 and hence the relative phasing of the outputs of the two microphones so that when they are in series they may either reinforce or oppose one another. In a third position of switch 26 (as shown) the microphones are disconnected. The microphones are of the ribbon type with the ribbons arranged end-to-end and are relatively rotatable about an axis parallel to the longitudinal axes of the ribbons. The microphone head 5 is detachable from the switch unit 4.
Patent GB-874173-A (GB)
Title: Improvements in or relating to resinous dispersions
IPC: C08J3/07
Filed: 1957-10-08
Abstract: An aqueous dispersion of a linear essentially unbranched, head-to-tail polypropylene having a content of crystalline polymer of from 50%-100% by weight is made by dispersing particulate polypropylene in water in the presence or absence of a dispersing or emulsifying agent.  The size of the polymer particles is preferably from 0,1-20 microns.  The aqueous dispersion may also contain a filler, pigment, or plasticizer.  The particulate polymer may be obtained by grinding it in the presence of an oily material or by forming a solution of polypropylene in a solvent, e.g. trichloroethylene, emulsifying the solution in water and then removing the solvent by evaporation.  The aqueous dispersion may be extruded into filaments and fibres or used as a protective coating, e.g. by removing the water after application to the surface and uniting the polypropylene into a coherent layer by heattreatment, or as an adhesive in laminates (see Group VIII).ALSO:Wires, plates, and cables are coated with an aqueous dispersion of a linear essentially unbranched head to tail polypropylene of crystalline content between 50 and 100%, and the coating after drying, consolidated under heat and pressure at a temperature above the softening point of the polymer.  The coating may be applied by spreading with a knife, roller, or brush, or by spraying.  The aqueous dispersion may contain dispersing agents, fillers, pigments, and plasticizers.

Title: Improvements in and relating to Nuclear Fuel Elements
Inventor: BOGDANOVITCH MICHEL
IPC: G21C3/04
Filed: 1969-06-23
Abstract: 1,197,880. Fuel elements. COMMISSARIAT AL'ENERGIE ATOMIQUE. 23 June, 1969 [3 July, 1968], No. 31496/69. Heading G6C. A vented fuel element comprises a stack of ceramic fuel pellets 3 surrounded by metal clading 1, the upper portion of which includes a first chamber 7 separated from the fuel material by a partition 4 through which a fission gas passage tube 10 extends into the chamber 7, which chamber is bounded at its upper end by a partition 5 formed with at least one capillary tube 11 providing a microleak orifice for a viscous material 13 contained in a second chamber 8, a third chamber 9 separated from the second chamber 8 by a partition 6 through which a duct 14 extends into the chamber 9, and apertures 15 in the side of the cladding 1 at a level below the top end of the duct 14 through which fission gases can escape from the chamber 9. The microleak may alternatively be provided by a porous metallic or ceramic sintered member or by a non- return valve (e.g. a ball co-operating with a seat). The material 13 is such as to be viscous at the fuel element working temperature and pasty or solid at a lower temperature. Advantageously, the material 13 is a salt meltable at the working temperature, a glass, or a metal, alloy or eutectic. The element is shown as being immersed in a fluid coolant 16, e.g. molten sodium, and the space in the chamber 9 above the coolant contains an inert gas, e.g. argon or helium. In operation, the fission gases pass through the tube 10 and collect in the chamber 7 which they gradually occupy, simultaneously as the resulting pressure causes the material 13, previously introduced through the capillary tube 11 from chamber 8, to be forced back into this chamber. When the liquid level reaches the bottom of the tube 11, the fission gases escape into the chamber 8 where they start to collect again. They leave chamber 8 through duct 14 and collect in chamber 9, mixing with the inert gas. The volume of gas in chamber 9 increases gradually, the coolant level decreasing simultaneously until reaching the level of the apertures 15, whereupon the fission gases are finally free to depart to the outside from the cladding 1.

Filed: 1925-12-18
Abstract: 267,616. Standard Telephones & Cables, Ltd., (Deakin, G., Goemaere, and Polinkowsky, L.). Dec. 18, 1925. Automatic exchange systems. - An impulseresponding relay has associated with it a marginal relay which operates if the impulsing loop is of abnormal resistance to effect compensating circuit changes or to switch in an alternative impulse-responding relay having different characteristics. Means is also provided to prevent release of the associated apparatus if, owing to the low resistance of the loop, the make period between impulses is so short that the releasecontrol relay might tend to fall back. In the system show, the marginal relay Msr is in series with one winding of the impulse relay ISr of a register-controller. If a subscriber's loop is of unusually low resistance, relay Msr operates, and inserts resistances C, D in series with the right-hand winding of relay ISr, the arrangement being such that during impulsing the operating winding of relay Msr is removed from the loop, this relay remaining locked over a second winding to cam B. Alternatively, the relay Msr may operate a change-over relay which substitutes for the relay Isr a relay particularly adapted to respond to impulses transmitted over low-resistance loops. In order to ensure that the releasecontrol relav ICr shall not release if the " make " periods between impulses are very short, this relay is provided with an alternative circuit over the back contact of a slow-operating relay NER which only pulls up when relay ISr remains deenergized for a period much longer than the ordinary duration of an impulse. Specification 206,578 is referred to.
