Abstract: A cartridge acting as a dispenser for liquid treatments of a human or animal body is U shaped or hoop shape. The cartridge has a container containing a liquid treatment which when required to be dispensed is ejected through one or more nozzles projecting through the wall of the cartridge into the centre of the U or of the hoop. A base is provided for cartridges, the base controlling timing and quantity of treatments.

Abstract: A drug or medical treatment dispenser comprises a hoop or a pair of semi-circular arms pivotally mounted together. The dispenser comprises at least one tube which is connected at one end to a pump. The pump is in turn connected to a replaceable container of treatment. The tube comprises one or more apertures to dispense treatment in spray form towards a body part of a person or animal which is placed within the dispenser.

Abstract: A heat generator comprises a fluid input and fluid output, an electrically conducting disc mounted on a shaft, a plurality of magnets with their N-S axis aligned parallel to the plane of the first disc are mounted either side of the disc, a plurality of runner vanes upstanding from the disc and forming a plurality of widening fluid paths towards the magnets and allow fluid to flow over a vane free portion of the disc to exit the heat generator though the output. Drive systems are described in which high pressure fluid from a hydraulic motor connected to a turbine or Archimedean screw is used to drive the disc.

Abstract: A drug or medical treatment dispenser comprises a tube having a plurality of apertures from which a treatment is spayed towards the skin of a person or animal.

Abstract: A large area detector (3) for use, for example, as an x-ray detector for medical imaging consists of a radiation sensitive detector (8) in combination with a monolithic amplification device consisting of a plurality of alternately stacked dynode and insulation layers having channels (6) extending therethrough in communication with respective signal collectors (10). The large area detector (3) is capable of being formed in tiles of 1 m2 or more whilst providing high resolution of the order of 50-60 pixels per mm2.

Abstract: The imaging machine which may form part of a photocopier, scanner or the like has a light source, a platen (21) consisting of an upper, light transparent plate (23) and beneath the upper plate an image collector unit (25) and an image data processor (30). The image collector unit (25) consists of a photosensitive sheet arranged above an array of electron multiplier channels. Light reflected from an object laid on the surface (24) of the upper plate (23) is converted by the photosensitive sheet into electrons that are multiplied by the electron multiplier channels to amplify the image of the object resting on the upper plate. The surface area of the electron multiplier array corresponds to the imaging area of the imaging machine making it possible for a complete image to be captured simultaneously across the entire imaging area rather than by means of scanning optics. Moreover, the use of the electron multiplier array enables lower powered light sources to be employed.
