Title: Increasing resistance to pull out of screws
Inventor: HENRY HUGH RICHARD
IPC: B25B27/14
Filed: 1985-06-28
Abstract: A method of increasing the resistance to pull out of a screw (20) screwed into a receptive substrate (35) which comprises unscrewing the screw and removing it from the hole and then locating a spiral member (140) having an outwardly facing pointed profile and having a cross section such as to fit between adjacent turns of the thread on the screw, and such that the dimension of a turn perpendicular to the longitudinal axis of the spiral (herein called the radial depth) is greater than the height of the thread of the screw with which that turn will be associated, in the threaded hole and screwing the screw into the hole, the spiral member engaging the hole and the screw threadly engaging the spiral member and forcing the pointed profile into the substrate. The spiral member is preferably of intermediately malleable material e.g. an aluminium alloy. The bottom end (146 or 182) of the spiral member is shaped so as to be disconnectably engageable by a tool (50 or 160). Application in the field of screw-in rail spikes in wooden sleepers.

Title: Hot water system utilising solar energy
Inventor: FARRALL TERENCE
IPC: F24D17/00
Filed: 1985-07-10
Abstract: In a solar heated domestic or commercial hot water system a preselected small volume of water may be circulated through a high level solar collector array (SCA), thereby accelerating temperature rise. In a repetitive process throughout all periods of solar gain, successive small volumes of hot water are discharged into the top of the systems normal gravity-fed main hot water storage vessel (HWSV) and/or into other chosen storage facilities. The system can provide preheated feed into the vessel; avoids the use of separate primary and secondary circuits and the special fluids and heat exchangers associated with same; and can automatically drain the solar collector to avoid frost damage. The system comprises three main elements - a vessel (V); a 3 port automatic diverter valve (3PV) and a pump (P). Suitable thermostatic and other controls, and system interconnections, are required. <IMAGE>

Title: Wound dressings
Inventor: WEBB ANDREW
IPC: A61L26/00
Filed: 1985-09-27
Abstract: Wound dressings comprise a poly 3-hydroxybutyrate polymer dissolved or swollen with a volatile solvent such as chloroform. The 3-hydroxybutyrate may be co-polymerised with for example 10-30 mol % of 3-hydroxyvalerate units and may be in sterilised form e.g. by gamma -radiation. On application to the wound the polymer adapts to the contours of the area to be treated and solvent evaporates to provide a film covering which is permeable to water vapour but impermeable to oxygen.

Title: Mounting arrangements for vehicle engines
Inventor: BEST ANTHONY
IPC: F16F13/26
Filed: 1985-10-17
Abstract: A vehicle engine mounting arrangement comprises a mount (13) between the engine (11) and body (10) of the vehicle and a support (14) between the body and suspension system (12) of the vehicle.

Title: Mechanical resonant system with controllable resonance
Inventor: FRENCH MICHAEL JOSEPH
IPC: F03B13/14
Filed: 1985-12-12
Abstract: The resilient means, which may be a mechanical spring or a gas spring, which provides the restoring force in a mechanical resonant system is arranged to be switchable between two or more states having differing rates of dependence of restoring force upon displacement from equilibrium. Thus a mechanical spring 11, 12 may be clamped at 13 to switch from the resilience of both parts 11, 12, acting together to the resilience of part 12 alone. By adjusting the time delay between switching, one obtains quasi resonance at any frequency within a range of frequencies. in an alternative system (Fig. 3) a first spring acts on the mass over the whole of its travel, while auxiliary springs act for only part of the travel. Systems using gas springs are described. The invention is applied to apparatus for extracting energy from waves on water. <IMAGE>

In lift thrust mode the jet-pipe is closed and the two sets of nozzles are open, the non-vectoring nozzle providing vertical thrust. The closure member 38 for each vectoring nozzle is arranged, when open, to divert turbofan air to the vectoring nozzles which would otherwise have passed along the by-pass duct, and to also divert to the vectoring nozzles exhaust gases from the plenum chamber that are constrained to flow in reverse along the by-pass duct. The non-vectoring nozzle is sized to permit a suitable split between gases exhausting there through and gases reverse flowing along the by-pass duct.
