Patent GB-847085-A (GB)
IPC: B63B35/04
Abstract: 847,085. Submarine cable laying. TELEGRAPH CONSTRUCTION & MAINTENANCE CO. Ltd. Nov. 20, 1957 [Nov. 27, 1956], No. 36246/56. Class 78 (5). [Also in Group XXXVI] The movement of a cable having enlarged sections, such as submarine repeater housings, is controlled during laying or taking up by an assembly of three sheaves 4<1>, 5<1> and 6<1> whose axes are normally in alignment and wherein the central sheave 5<1> is adapted to be displaceable to a position 10 in which the cable, together with any enlarged sections, is free to pass directly over the two outer sheaves, braking mechanism being associated with each sheave whereby progressive reduction in cable tension may be obtained. Two assemblies of sheaves 1 and 2 may be provided, one assembly e.g. assembly 1, providing braking action on the cable " C " during passage of the repeater housing " R " through the other assembly 2. The central sheave may be displaced by a screw jack or hydraulic ram, and braking control on each sheave may be obtained by connecting each sheave spindle through gearing to an hydraulic pump operating in a closed circuit through a leakage valve, adjustment of the latter providing appropriate variation in the braking effect of the pump load on the sheave associated therewith. Other forms of braking, such as a drum fitted to each sheave, may be used. Individual sheaves may be coupled together through differential gearing to obtain correct distribution of loading during raising or lowering of the central sheave.

Title: Foamed cement compositions for stowing cavities
Inventor: GARTSHORE GAVIN CRAMMOND
IPC: C04B38/10
Filed: 1985-09-12
Abstract: Compositions suitable for the production of foamed cements comprise an hydraulic cement clinker (for example a mixture of ordinary Portland cement with a high alumina cement or a 12CaO.7Al2O3-rich clinker), calcium sulfate, an air-entraining or foaming agent (especially an anionic sulfate or sulfonated organic surfactant) and a stabilising agent (especially a cellulose ether). Instead of the hydraulic cement clinker, a potentially hydraulic mineral clinker may be used in the presence of an activator, for example calcium oxide and/or hydroxide. The composition may also comprise an extender (for example blast furnace slag), a clay (for example bentonite) and setting accelerators, for example inorganic salts (for example alkali metal carbonates). The compositions may be made up with water and then foamed by the introduction of a gas, for example air, the resultant foamed cement being especially useful for filling cavities in underground mines.

Title: Aircraft runway with grooved surface
Inventor: CLARKE RONALD ALBERT WILLIAM
IPC: E01C11/24
Filed: 1988-02-10
Abstract: A manner of providing grooves in the surface of an aircraft runway (1) is described. The grooves (6N, F) are of skewed V-shaped in cross-section, having a steeply-sloping face (8) and a gently-sloping face (9). The grooves (6N, F) face in opposite directions at the tow ends (3N, F) of the runway (1): each groove (6N, F) is orientated so that the gently-sloping face (9) is toward the adjacent end (3N, F) of the runway (1). A benefit of the arrangement is to combine a resistance to aqua-planing upon landing at high speeds on a wet runway, (1), at one end (3N) of the runway (1), with a good friction grip between tire and runway (1) for emergency braking at the other end (3F) of the runway (1). This benefit is present when the runway is used in either direction.

Title: Silicon bipolar phase modulator
Inventor: WELBOURN ANTHONY DAVID
IPC: G02F1/015
Filed: 1989-03-30
Abstract: An electro-optic bipolar phase modulator comprises a laterally-confined waveguiding channel (1) formed in a lightly- doped silicon layer (2), and a heavily-doped silicon sub-layer (3) of opposite polarity. The modulator is provided with three electrodes (4, 5, 6) for controlling the carrier density within the channel (1), thereby modulating light propagating in the channel by varying the refractive index of the channel. The three electrodes (4, 5, 6) define a bipolar transistor structure. Modulation is achieved by alternating between first and second predetermined voltage regimes applied to the electrodes (4, 5, 6), the first predetermined voltage regime driving the bipolar transistor structure into the saturation mode, and the second predetermined voltage regime driving the bipolar transistor structure into the cut-off mode. The channel is fully open when the transistor structure is in the saturation mode, and fully depleted when the transistor structure is in the cut-off mode. Alternation between the predetermined voltage regimes is of a quasi-digital nature. <IMAGE>
