Title: Method of constructing a long pipeline on the floor of a body  of water
IPC: F16L1/16
Filed: 1972-09-18
Abstract: 1434357 Laying sub-aqueous pipes T H DUYSTER 17 Dec 1973 [18 Sept 1972] 43167/72 Heading B7M [Also in Division F2] A method of constructing a pipeline on the floor of a body of water, e.g. ocean, in which during transportation under water and laying and connecting to existing pipeline a long perfabricated pipe section is subjected to tensile forces and kept in a floating position. In the embodiment shown in Fig. 2, the tensile forces in the pipe section 1 are produced by vessels 2 (only one shown) connected to opposite ends of the pipe section 1 by cables 4, which pull in opposite directions with different forces to give a net movement in direction A. The pipe section 1 is kept in a floating condition by means of submarine floats 5 and individually adjustable buoyancy floats 7 connected to the pipe section 1 by claws 8, releasable by means of explosion bolts 22. The floats 7 have a pressure chamber 12 filled partly with air or another gaseous medium under pressure and partly with water or another liquid and have an opening in the lower part connected to a valve 10 responsive to the external water pressure. The valve 10 comprises a piston 23 positively acted on by compressed air in line 11 and by the external water pressure such that the pipe section with float at a depth determined by the pressure in the line 11. Thus excess pressure in line 11 urges piston 23 downwards allowing water under pressure from conduit 9 to be admitted to the float 7 via a duct in piston 23. With excess external pressure the piston 23 is urged upward to allow fluid to be expelled from float 7 by the pressurized gaseous medium therein. In another embodiment (Fig. 1, not shown) the pipe section 1 is provided with weights along its length at regions suspended from vessels (3) by means of cables (19) the vessels (3) being provided with elements (6) which compensate for the movements of the vessel due to waves. During the laying of the pipe section it is guided in a transverse horizontal position by means of additional vessels which support the pipeline by means of cables. These vessels may be those already supporting the pipe section as in the embodiment of Fig. 1, or vessels which connect to the pipe section by means of floatable cable pulley units (15) releasably mounted on floats 7 with explosion bolts (16). The pipe section may be guided transversely by further surface vessels (not shown).

Abstract: 1464744 Selective signalling; theft alarms H P VINET 7 Oct 1974 [5 Oct 1973] 43416/74 Headings G4H and G4N A workshop installation for checking, servicing and repairing e.g. vehicles, household equipment &c., includes at least one enclosure to which coresponds a pre-payment device which controls, as a function of time spent, one or more electrical warning circuits and a mechanism for locking a barrier situated at the entrance to the enclosure, the enclosure containing tools and equipment which are subject to presence detectors which are connected to one or more electrical warning circuits and to the mechanism for locking the barrier. The presence detectors for small tools are switches actuated when the tool is returned to a tool-shaped depression in a tool board, to detect attempts to leave the enclosure without replacing the tools in the board. The switches may be mechanical or reed-relays or respond to the weight of the tool. Attempts to remove larger items are detected in that it would require severing of wires e.g. in power cables for the items. These two types of attempts give separate alarms at a central station, which also includes occupied/empty indicators for the enclosures, time out indicators, barrier control buttons, telephone facilities for talking to the people in the enclosures, &c. In the vehicle application, lifting ramps and pits in the enclosures may have arrays of contacts on the ground to detect incorrect positioning of the vehicle as it approaches and light direction signs. The ramp or a covering panel for the pit may be controlled in accordance with the vehicle position for safety.

Abstract: 1,087,486. Electronic counters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct.14, 1965 [Oct. 27, 1964], No. 43566/65. Heading G4A. [Also in Division H3] A counter is formed from bi-stable circuits comprising two switching elements 1, 2 each controlled by a pair of logic circuits 5, 6 and 8, 9, a source of complementary signals (applied respectively to the upper inputs of 5 and 8) for switching the elements, the logic circuits of each pair being satisfied alternately as the circuit changes state and a delay circuit 11, 12 for delaying the logic of one circuit of each pair. Assuming inverter 1 is producing a " 0 " and inverter 2 a " 1 " and then a " 1 " is applied to the upper input and a 0 is the lower. The output of gate 6 becomes 0 and this initiates the cut-off of inverter 1. Gate 5 would produce a " 1 " but this is delayed by capacitor 11 and does not prevent this operation. As element - 1 conducts a " 1 " is applied to gate 9 and as the upper input is also " 1 " element 2 is rendered conducting. Thus switch-over is effected after which the return of the inputsignal to the rest condition does not affect the operation. The circuit is symmetrical and restoration of the original state is effected in the same manner. In Fig. 2 (not shown), the inverters are transistors and the logic is effected by diode gates. The capacitors (11 and 12) act as delay elements for one input but as " speed-up " capacitors for the diode which they share. An isolating diode (52) is also connected to input 51. A member of the bi-stable element may be connected in cascade to form a counter (Fig. 3, not shown).

Title: Fuel elements for high-temperature reactors in which the structural graphite is particularly suitable for reuse
IPC: G21C3/28

Abstract: 1433889 Fuel elements; processing spent nuclear fuel HOBEG HOOHTEMPERARURREAKTOR-BRENNELEMENT GmbH 20 Sept 1973 [20 Sept 1972] 44097/73 Headings G6C and G6R In a fuel element for high-temperature reactors from which the fuel can readily be removed from the structural graphite after burn-up of the fissile material, so that the fuel element can be filled with fresh fuel and reintroduced into the reactor, the strength of the matrix is sufficient to bond the embedded coated fuel particles but is substantially lower than that of the structural graphite so that the matrix can readily be split by the application of force so that it can be removed from the graphite block without damaging either the fuel particles or the graphite block. The matrix used preferably consists of graphite filler with only very small binder contents, i.e. with less than 10% by weight. A natural graphite powder is preferably used as filler. The new fuel inserts, which have been pressed in known manner from pressing powder and coated particles, and carbonized and further heat-treated, are introduced into the bores of the graphite block. The inserts are only lightly precompressed, pushed into the bores with a ram and then fully compressed so that they closely follow the walls of the bores. After the block has been filled and the bores closed, e.g. with either a screwthreaded plug of structural graphite or a plug of matrix graphite without fuel, the block is heated to around 1000‹ C. to carbonize the matrix and then held briefly at around 1800‹ C. In a fuel element block coming from a reactor, the threaded plug of structural graphite is initially unscrewed or the fixed plug consisting of matrix graphite bored out with a crown bit. The fuel can then be loosened with the same crown bit or with a spiral bit or milling cutter. This operation is carried out from beneath so that the loosened fuel particles and crumbs of matrix graphite drop freely out of the bores of the graphite block. In cases where a spiral bit is used, it is advantageous to displace the loosened particles pneumatically from the block through a bore inside the spiral bit to prevent blockages in the event of poor material flow. Pneumatic displacement of the fuel is also possible where crown bits are used. Alternative methods of fuel removal employ erosion or ultrasonics.
