A centre chamber 31 of a fluid-tight stressrelieving pipe joint, open to the inside of the pipe through holes 33, and sealed by a bellows 30, provides a pressure differential which opposes separation of slidably telescoped pipes 10, 20 due to fluid pressure; two other chambers 32, 34 are sealed by bellows 30, preventing fluid escape from the pipe and chamber 31, respectively, and the three bellows 30 are connected to flanges 12, 13; 23, 22 fixed to the pipes 10, 20, respectively. Chamber 34 is open to chamber 31 and the difference in annular areas of the two chambers provides the pressure differential. The chamber above the two right-hand bellows 30 is open to the atmosphere at 35 so that equal pressures exist outside all of the bellows 30. The three bellows 30 may be made of metal or a heat-resistant high-strength elastic synthetic material.

Abstract: 1,238,839. Nuclear radiation detectors. FIZICHESKY INSTITUT IMENI P.N. LEBEDEVA. Sept.22, 1969 [Sept.20, 1968; Jan.31, 1969], No.46681/69. Heading G1A. [Also in Division H1] A type IIa or intermediate type diamond nuclear radiation detector 2 is provided with one injecting contact 4 and one blocking contact 3 made of a metal carbide such as tantalum carbide or platinum carbide. The thickness of the detector 2 is less than the carrier diffusion length. The arrangement is suitable for use in a corrosive radio-active medium. The injecting contact 4 may be formed by doping the diamond surface with boron, and wires 15, 17 may be joined to the two contacts by means of silver paint. As shown the detector 2 is sealed into a hermatic housing 5 by means of gaskets 7, 8, and the nuclear radiation under investigation impinges upon the diamond 2 through the blocking contact 3, which seals a window 6 in the housing 5. Two diamond detectors may be mounted together with their injecting contacts connected, or a mosaic of such detectors may be employed. The arrangement is used with a power source 24 connected to the injecting contact 4 and amplifier 21 and recorder 22 connected to the blocking contact 3. Alternatively the lead 11 from the injecting contact may be grounded, the power being applied and the output taken both from the blocking contact 3, the latter via a capacitor.

A fuel container comprises a foamed polyamide core and unfoamed surface skins of propylene polymer. The core may be of nylon 6, nylon 66 or a copolymer of nylon 66 with nylon 6 or polyhexamethylene isophthalamide, and the skins may be of polypropylene or a copolymer of propylene with ethylene or butene. The container may be made in one or two pieces by injection moulding in a vertical flash mould. A charge of propylene polymer is first injected into the mould, and before this has set, a charge of polyamide containing a blowing agent (which may be a solid or a liquid) is then injected, preferably through the same orifice, and the material is allowed to foam and set. Preferably a second charge of propylene polymer is injected after the polyamide charge to avoid exposing the foam core on removal of the sprue. The core material is preferably injected at foaming temperature but at a speed and pressure that pervent foaming until the mould is filled, the mould cavity then being enlarged to allow foaming.

Abstract: 1,253,212. A board game. H. E. WICKS. 11 Feb., 1969 [15 Feb., 1968], No. 7344/68. Heading A6H. A board game similar to draughts is played on a checker board 10, with counters 14, marked with either a '1' or a 'O'. The counters are moved one square at a time, either diagonally, vertically or horizontally in any direction. A player both disposes of an opponent's counters and increases the number of his own counters if he can place one of his own counters at the roof of a column of opposing pieces to form a "sum". The process is completed by performing one of the operations of binary arithmetic, the player placing his own counters in the "answer" and removing the other counters. In the embodiment given, the object of the game is to achieve a particular configuration of counters on the opposite back-row.

Abstract: 1,259,044. Testing recoil mechanisms of guns. FRANCE ARMED FORCES MINISTER OF. 18 March, 1970 [19 March, 1969], Nb. 13141/70. Heading F3C. The invention relates to a method of and apparatus for testing the recoil: mechanism of a, gun by applying a force to the muzzle of the gun to create an acceleration of the barrel of the gun. The method comprises the steps of compressing a gas in a gas compressionexpansion system and then releasing the energy stored in the gas by allowing it to expand to apply accelerationto the barrel.. The apparatus disclosed. for carrying out the method includes a cylinder housing a piston P, which piston divides the cylinder into a gas chamber A and an hydraulic chamber H. The cylinder is provided with outlets O to a valve assembly and throttling orifices F and the piston is provided with a rod T the outer end of which co-operates with a. thrust block B.. The block B is rotatable by an assembly R so that in the acceleration producing stroke the block B and rod T move together until at a a predetermined time the block B is rotated such that splines C1, C2 on the block B and. rods T interengage to allow the block B to slide relatively to the rod T under the action of a spring R1 (Fig. 3b, not shown). The gas, e.g. nitrogen, is compressed by pumping hydraulic fluid into the chamber H until the required pressure is achieved. The valve assembly which comprises a piston P1 mounted on an unstable linkage B1, B2, B3 is actuated by the electrical operation. of two fingers. V1, V2 to allow the piston P1 to move in response to the hydraulic pressure to uncover vent conduits Cd. The link B3 is pivotally connected to a shockabsorbing piston P2 through a member which comprises the piston of a shock-absorbing arrangement, the. piston P2 forming the cylinder thereof. The movement of the piston P at the end of its working stroke is braked by the co-operation of a cylindrical sleeve Ta of the cylinder with a cavity in. the piston P.

The tube 14 made of stainless steel or gilding metal, is wholly or partly corrugated to form a bellows and is closed at its end 20 by a valved piston 21 reciprocable within an outer casing 12 fitted with an internal tubular lattice structure 25. The piston is biased by a spring 22. An outlet pipe 18 for primary liquid has an electrically actuated interrupter valve 19 which produces a pulsating pressure in the corrugated tube 14 whereby piston 21 is reciprocated. This causes secondary water to be drawn in through valve 23 and discharged through outlet 26; alternatively the valve 19 may be replaced by a twoway valve which switches the primary flow alternately between the radiator and domestic water circuits, or the pump itself may produce a pulsating pressure. The primary connections 26, 18 may be reversed. Instead of or in addition to reciprocating, a rotary or radial oscillation may be given to the tube 14.
