The detectors specify a plurality of emission probability fields which intersect in space to form a reduced emission probability field.

Abstract: A nutmeg emulsion is made by dissolving powdered nutmeg kernels in a solvent, e.g. alcohol, to extract nutmeg flavor fats and oils therefrom. The extracted flavor fats and oils are diluted with water to form the emulsion. All steps in the process of making the emulsion are performed at room temperature to avoid loss of nutmeg aroma and spicy flavor.

Abstract: This automotive steering wheel lock is made up of a rod and a cartridge connected with the rod. The cartridge consists of an upper half cartridge and a lower half cartridge that capture hold of the steering wheel between them and are locked with a lock cylinder and a lock base set separately in the two half cartridges when said half cartridges are closed together. To open the lock, a key is inserted and turned in the keyhole of the lock cylinder. The bottom of the rod can be blocked by the driver's seat or something inside the car or by a thief's body making it difficult to handle the steering wheel, even if the steering wheel should be turned around with the lock locked in an attempt to steal the car.

The vehicles have a cream-like consistency and can also incorporate suitable compatible plasticizers, coupling agents, penetrants and the like.

Abstract: Separation of relatively magnetic and relatively non-magnetic particles suspended in a fluid medium is effected by feeding a stream of the medium across at least one end face of a magnet so as to cause the magnetic and non-magnetic particles to diverge and to be directed into separate collector channels.

Abstract: An optical switching device comprises an optical waveguide formed from two light-transmitting materials having an interface between them, and in which the refractive index of one of the materials can be altered by an external influence; the other has a light path directed at the interface at an angle such that by varying the refractive index of the first material the light can either pass through the material or be reflected at the interface. By utilizing a plurality of such interfaces in sequence the light may be selectively switched along several different paths.

Abstract: An arrangement for and method of generating hydrogen wherein hydrogen and hydroride are generated by reacting hydrogen hydride with water. The hydrogen hydride is generated by subjecting hydroride to cryogenic temperature and subatmospheric pressure conditions. This cycle is repeated with the resulting liberation of hydrogen. The hydroride is produced initially and as needed by subjecting water to the action of light photons.

Abstract: A night vision viewing system, suitable for mounting on an observer's headgear (11), wherein light rays from a forward scene pass to the observer's eye (E) via a path comprising a forward looking objective lens (23), an inclined reflector (35) which directs the rays passing through the objective onto an outwardly sideways looking input face of an image intensifier (31), and a fibre optic stub (33) which directs rays from the output face of the intensifier onto a second reflector (27) which directs the rays downwardly into an eyepiece (21) which is in the observer's forward line of sight. The eyepiece incorporates an internal surface (37) having both light reflective and light transmissive properties which directs rays entering the eyepiece from the intensifier to the observer's eye. The fibre optic stub serves to effect rotation of the intensified image to present an intensified image of correct orientation to the observer.

Abstract: A combined lock for a steering wheel and a hand brake, wherein a steering wheel lock is used to lock the steering wheel immovable and an extensible bar lock is used to lock the hand brake immovable. Said steering wheel lock is combined with the extensible bar lock by means of a steering wheel lock tube and an extensible bar movably contained in said tube and in said extensible bar lock, said bar pivotally connected with a hand brake cylinder; therefore, after the steering wheel locked, adjusting the extensible bar, shielding said cylinder around the hand brake and locking the extensible bar lock can lock both the steering wheel and the hand brake immovable at the same time.

Abstract: A vacuum valve device comprises a substrate on which is formed an updoped silicon layer from which a silicon dioxide layer is grown. First, second and third electrode structures are formed on the silicon dioxide layer by depositing a metallic layer and etching away unwanted portions of the layer. The first electrode structure has a pointed end and/or a sharp edge and/or is formed of low work function material so that, when a suitable voltage is applied between the first and third electrode structures, electrons are emitted from the first electrode structure due to a field emission process. Electrons therefore flow from the first to the third electrode structure substantially parallel to the substrate. The second electrode structure acts as a control electrode.

Abstract: A method and apparatus for using stored data to produce a representation of a surface from the perspective of a platform moving across the surface (e.g. of ground terrain from an aircraft overflying the terrain) wherein the representation comprises a perspective view of an array of elements modelling the surface and the orientation of the array with respect to the surface changes with the direction of movement of the platform across the surface so as to keep the array aligned with the direction of platform movement and so avoid confusing changes in the display with changes in platform movement direction.
