Title: Heat treatment of uncalcined, carbon-containing fireclay
IPC: C04B20/04
Filed: 1980-07-14
Abstract: Particles of uncalcined, carbon- containing fireclay are heat treated in a kiln through which an air draft is maintained. The air draft or the kiln atmosphere is enriched in oxygen by adding to it a gas containing more oxygen than air. This makes possible maintenance of an oxidising atmosphere in the kiln thereby ensuring complete oxidisation of the carbon. The kiln may be a vertical shaft (as shown) or a rotary kiln. The vertical shaft kiln 2 has three sets 4, 6, 8 of burners used to fire the raw fireclay. Air is supplied through calcined fireclay outlet 10 and ports (not shown). The raw fireclay is fed into the top of the kiln 2 from a hopper 16. Heat treated fireclay is continuously discharged from the outlet at the bottom of the kiln so that there is a progressive movement of the charge down the kiln. Each set of burners raises the temperature of the fireclay. Pure oxygen is introduced into the kiln through lances 12 located just above the intermediate set 6 of burners. <IMAGE>

Title: Control in response to eye closure for the handicapped
IPC: A61B5/11
Filed: 1981-05-08
Abstract: To produce a control signal in response to closure of the eye, a visible light transmitter 15 and receiver 16 are mounted on a spectacle frame or similar so as to be situate above and in front of the eye. Conductors 19 are connected to a control circuit arranged to supply modulated current to the transmitter 15 and to respond to changes in light levels received by the receiver 16. The open eye reflects little light, but the scattering effect of the eyelid when the eye is closed reflects a greater amount of light to the receiver 16. Comparing the phase of the transmitted and received light allows effects of ambient light to be eliminated, and a delay circuit discriminates deliberate eye closure from blinking. A computer may display a sequence of characters on a visual display unit and respond to the control signal so as to store for further processing e.g. printing the character being displayed at the time. The control signal may control other equipment e.g. a wheelchair. <IMAGE>

Title: Multi-engined VTOL aircraft
Inventor: SNELL LEONARD STANLEY
IPC: B64C39/08
Filed: 1981-06-20
Abstract: In a multi-engined VTOL aircraft the out-of-balance thrust produced by an engine failure during vertical take- off is countered by vectoring the thrust of the remaining engines in both the transverse and fore and aft planes to keep the thrust vertical whatever the aircraft attitude. As described, the aircraft has eight engines 8 mounted on wings 4 and 6 and each engine 8 has a nozzle 12 from which the engine thrust can be directed with rearward and downward components of velocity. The centre of the lifting thrust is arranged to be above the aircraft centre of gravity so that the aircraft will pitch and roll only until the centre of gravity lies below the new lift thrust centre and will then stabilise in a tilted attitude. A general mathematical theorem is discussed which indicates the constraints on the positioning of the engines on the aircraft, and the requirements for an automatic control system are outlined. <IMAGE>

Title: Functional agglomerated speckles and dentifrices containing them
Inventor: GIBBONS EDWARD J
IPC: B01F23/57
Filed: 1982-09-29
Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose, and may sometimes preferably also include a water soluble binder, such as polyvinyl pyrrolidone. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to a main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavouring and surface active agents, which may controllably soften the speckles on storage.
