Abstract: A multi-pin plug and socket electrical connector in which adjacent pins are sealed from each other at the interface by an elastomeric sheet. The sheet extends over the entire interface with each pin extending through a hole in the sheet. Each hole is surrounded by a O-ring integral with the sheet. The sheet may extend within each O-ring to make contact with the pin. The pins are sealed at their opposite, i.e. wire ends by individual elastomeric seals in the pin bores.

Abstract: A manually operable electrical toggle switch (60) is connected in a low current signalling link (40) via a non-intelligent slave unit (20) in a time slot assignment multiplex system for automotive vehicles to an intelligent master unit (10) which in response to a binary input from the switch (60) provides an output signal on such a signalling link (40) to control high current to a load (70) connected to a slave unit (20). The switch (60) has conductive plastics contacts (63) to avoid oxide corrosion problems and may be all plastics. The binary input from the switch (60) is provided by one of two resistances (R2or R3) which are distinguishable in the master unit (10) from each other and from both a short circuit and an open circuit in the signal line (42) of the link (40).

Abstract: A temperature sensing and measuring system in which a luminescent material is excited using a light source. The luminescence emitted decays with time, the decay time being dependent on temperature. Thus by monitoring the excitation and luminescence transmitted to and from the material via an optical fibre, the decay time constant and thus the temperature can be determined.

Abstract: An impact fuze arrangement for a missile in which an electromagnetic field is set up within a compartment in the body of the missile and a warhead detonating signal is generated if the field intensity varies by more than a predetermined amount, as will happen due to distortion of the compartment on impact of the missile on a target. Fields may be set up within a plurality of compartments and warhead detonation may be made conditional on distortion of more than one of these compartments.

Abstract: A helmet mounted binocular goggle night vision viewing system comprising two independent night vision viewing arrangements, one for each eye of a wearer of the helmet, supported from above the face aperture of the helmet, each viewing arrangement comprising an optical projector arranged to project an intensified image of a scene ahead of the helmet wearer downwardly to a body of light refractive material in front of the wearer's eye having parallel flat fore and aft surfaces spanned by an upper surface via which light from the projector enters the body for reflection towards a curved partially reflective, partially transmissive surface within the body by which the light is reflected back towards the aft surface for transmission therethrough to the wearer's eye, thereby to provide the wearer with a view of the projected image superimposed on his view of the scene ahead through the body.

Abstract: Several cables extend between a buoyant body to be moored and the sinker on the sea bed. Intermediate spacing members hold the cables apart from one another to maintain the configuration. At zero rotation when the tether formation itself is in equilibrium half the number of cables exert a clockwise torque and half exert an equal and opposite anticlockwise torque. Any small rotation of the moored body causes the tension to increase in the cables opposing such rotation and to decrease in the other cables, so the body is restored to the equilibrium position. The tether thus exhibits high torsional stability. Cables can be configured to enable the tether to tilt relative to the buoyant body or sinker whilst still retaining high torsional stability.

Abstract: An electric power measuring device wherein input analogue signals representative of instantaneous values of current and voltage are applied to a multiplier (23) and the resulting product signal is applied to a converter (35, 37, 41, 43, 45, 47) to provide a pulse output signal having a pulse rate representative of the product, and hence of the level of power consumption. The converter is of the kind including a capacitor (35) which is charged during successive periods of equal duration by the product signal and a much larger reference signal which reverses at the end of each capacitor charging period until the capacitor charge does not reverse in polarity during a charging period, so that reversal of charge on the capacitor is assured during the next charging period, whereafter the direction of the reference signal is again reversed at the end of each charging period.

Abstract: Intestine-specific delivery of an opioid antagonist can be accomplished without substantial central nervous system effects by administering the antagonist orally in the form of the glucuronide derivative.

Abstract: The present invention concerns a rising sun magnetron comprising an anode ring having a series of radially inwardly-projecting teeth-like elements of a relatively high thermal coefficient of expansion. Each element (27) has a vane (21) of material of relatively low thermal coefficient of expansion secured on either side thereof so as to define alternate long and short cavities and an associated length of material (26) also of low coefficient of thermal expansion lying between the adjacent pair of vanes (21) and acting as a fulcrum for the associated vanes when the element (27) expands due to temperature rises.

Abstract: A combustor for a gas turbine engine. The combustor employs an array of fuel injectors arranged across and in the mouth plane of the combustor flame tube. Each injector has a baffle plate through which the injector nozzle projects, the baffle plate having axial holes for atomization air to intercept and atomize radial fuel jets from the injector nozzle. Cooling of the flame tube is performed by full coverage impingement and effusion without disturbing the cooling film by entry and penetration of transverse air jets. Flame stabilization is achieved under all required operating conditions by the radial-fuel/axial-air atomization in conjunction with the baffle plates. Comprehensive combustion mixing and dilution is achieved by the uniformly distributed supply of up to 90% of the total air supplied to the combustor around and through the baffle plates.
