Title: A low-vulnerability helicopter rotor blade
Inventor: BAZIAC GILBERT FRANCOIS
IPC: B64C27/473
Filed: 1986-10-06
Abstract: A low vulnerability helicopter rotor blade has a spar member 1 forming the leading edge of the blade which over most of its length is of box section having its upper and lower portions formed as a wide meshed lattice from strips of high strength fibres. The lattice bounds cells of low strength material which can rupture in the event of excess pressure in the box section to minimise damage to the spar member.

Title: Ladder conversion kits for roof-scaling
Inventor: LEE GORDON F
IPC: E04G3/26
Filed: 1986-10-16
Abstract: Pairs of frictional grip-boards A whose undersides carry soft plastics foam or the like are equipped with means for temporary fixing to one face of a ladder-section, near to its respective ends, enabling the ladder to adhere to sloping tiled surfaces and thus be employed for roof-scaling or as a safe structure on which to stand while working upon roofs. Two elaborations are described, one involving use of a small wheel B at the edge of each grip-board, the other employing circular rotatable grip-boards F, each version permitting the associated ladder to be rolled up a roof when tipped onto its edge. A ridge-hook attachment is included for use when it is necessary to reach the apex of extra-steep or slippery roofs, and modifications of this attachment are proposed as an aid to associated ladder operations. <IMAGE>

Title: A turbopropeller gas turbine engine intake
Inventor: FLATMAN RICHARD JAMES
IPC: B64D33/02
Filed: 1987-04-14
Abstract: A gas turbine engine 40 of the type which has a propeller 12 positioned upstream of the gas generator 14 comprises intake openings 20 supplying air through intake ducts 22 and annular intake duct 26 to a gas generator 14. A separating duct 24 removes foreign bodies from the air flowing through the intake ducts 22 and discharges them through an outlet 72.

Title: Vessel positioning system
Inventor: HAYNES ANTHONY PATRICK
IPC: G05D1/02
Filed: 1987-10-26
Abstract: To maintain a floating vessel 1 within a predetermined geographical area, a plurality of sensors 6 are positioned on the surface on which the vessel floats at a distance from the vessel so as to sense environmental conditions such as winds and currents which will in due course exert forces on the floating vessel. Those forces are predicted by a model on the basis of information provided by the sensors, and forces are applied to the vessel to adjust the position of the vessel relative to the predetermined geographical area in dependence upon the predicted forces so as to counteract those forces. The system thus anticipates the arrival of waves or other environmental effects so as to enable those effects to be counterbalanced by relatively small forces. As shown the vessel 1 is moored by a cable 2 to a buoy 3 connected to a riser of an oil well (not shown). <IMAGE>

Title: Sorting ore particles
Inventor: NORDIN LEE
IPC: B07C5/34
Filed: 1987-11-18
Abstract: Particulate material e.g. ore particles is sorted on the basis of the degree of attenuation of microwave radiation by the individual particles. The particles are fed via belts 16, 28 to a detection zone 28 which includes a microwave chamber in which is located wave guide antennae (50) which apply microwaves to the chamber and detect signals propagated through the particles as they pass through the chamber. Processing unit (52) analyses the signals and determines which of the particles exhibit a selected signal attenuation characteristic. Line scan camera (40) provides signals to unit (52) indicative of the relative rise and location of the particles and on the basis of these signals unit (52) controls ejector manifold (41) to eject the relevant particle. Particles of kimberlite can be sorted from gabbro using a microwave frequency of 35 GHz, particles sorted on the basis of water content using a microwave frequency of 246Hz, particles of gold bearing rock from waste rock and particles of coal from waste rock. <IMAGE>

Patent GB-2207794-A (GB)
Title: Electro-optical apparatus
Inventor: FUJITA MASANORI
IPC: G09G3/36
Filed: 1988-07-13
Abstract: In a matrix electro-optical apparatus usable in a display or an optical printer and including a ferro-electric material, a desired signal D5 or RD5 is applied to one set of electrodes and the other set of electrodes is supplied sequentially with initialisation, selection and non-selection signals RS24, S5, NS6, and the combined voltage of the initialisation and desired signals set a matrix electro-optic element firstly to a one of saturated ON or OFF states and then to a state below the threshold value for reaching the other state. An element is then quickly set to the other state by the selection signal S5 if a desired selection signal D5 is present. This enables both scan period and display renewal time to be shortened appreciably. The non-selection signal is for maintaining the state attained. High frequency pulses may be superposed on D.C. pulses for A.C. stabilistion. The initialisation signal may be a single signal having two pulses of opposite polarity as shown or include a number of signals applied sequentially to the scan electrodes. Intensity modulation control is also disclosed.

Title: Vibration-sensitive intrusion detection system
Inventor: HOYLE ROGER WILLIAM LESLIE
IPC: G08B13/12
Filed: 1988-08-17
Abstract: An intrusion detection system for detecting attempts to penetrate a vertical barrier such as a fence or wall includes a strain sensitive cable 10 which generates an alarm signal in response to movement of the barrier. The alarm signal is amplified 12 and filtered 14 and passed to a detector circuit 16 when it is rectified and converted to an envelope signal characteristic of the time taken for the alarm signal to rise from zero to its peak value (the rise time). The envelope signal is differentiated 26 to remove slow rise time signals and then supplied to a threshold detector 32. Signals which exceed the pre-set threshold value are counted 34 as to their frequency in a pre-set time period determined by a timer 36. Repeated signals in excess of the threshold value lead to activation of an alarm circuit 38 as being indicative of an intrusion. Any long term continuous signal generated by the cable 10 is detected by a second threshold detector 44 which will also activate the alarm circuit 38 if the signal persists for longer than a pre-determined period measured by a timer 46. <IMAGE>

Title: Pressure reducing valve
Inventor: PATEL MILAN NANDUBHAI
IPC: F16K17/19
Filed: 1989-04-28
Abstract: A pressure reducing valve (1) is mounted directly on a high pressure (300 bar) gas cylinder (23). When a standard adaptor is inserted in the outlet (4) and handwheel (20) is opened gas is available at outlet (4) at a maximum pressure of 200 bar. When a special filling adaptor (24) is inserted in the outlet (4) the cylinder can be refilled to its maximum pressure of 300 bar. The special filling adaptor (24) has a seal (25) which inhibits gas flow from a chamber (28) via a passage (22) to the surrounding atmosphere. This, in turn, inhibits a piston (8) moving downwardly to close the inlet (3) of the pressure reducing valve (1) as would be the case in normal service.
