Title: Improvements in liquid jet-producing apparatus
Inventor: SCHMIDT JOERGEN
IPC: B05B9/04
Filed: 1989-11-03
Abstract: In an apparatus for ejecting liquid through a jet-producing means (2), e.g. a high-pressure cleaner, in which variations in the flow resistance through the jet-producing means (2) influence means in a pumping and processing unit (1) such that the liquid is supplied to the jet-producing means (2) under a higher pressure, when the jet-producing means (2) exhibits high flow resistance, and conversely, an ejector (11) is placed between the pump (9) and the jet-producing means (2), the suction inlet (15) of said ejector (11) being connected to the source of liquid (7) through a non-return valve (13). The ejector (11) will aspirate liquid through suction inlet (15) and hence deliver a larger quantity of liquid under low pressure to the jet-producing means (2), when the latter exhibits a low flow resistance, whilst when the jet-producing means (2) is set to a higher flow resistance, the ejector (11) will no longer function, as non-return valve (13) is closed, and liquid flows in a smaller quantity, but under a higher pressure through the ejector to the jet-producing means (2). <IMAGE>

Title: Photochromic imaging process
Inventor: DOBSON PETER
IPC: G03C1/73
Filed: 1990-01-17
Abstract: A process of imaging a film containing a photochromic compound, which is a fulgide or fulgimide that can reversibly be converted by UV light from a relatively colourless form to a coloured form, includes the step of exposing the film to UV light in one or more selected areas to convert the photochromic compound at least partially to the coloured form in those areas, the photochromic compound in the remaining areas being in the relatively colourless form. The process is characterised in that the film so exposed is heated, either simultaneously with its exposure to UV light or subsequently, to a temperature, preferably in the range 50-180  DEG C, at which the coloured form of the photochromic compound is degraded to a relatively colourless permanently non-photochromic compound but the relatively colourless form of the photochromic compound is not degraded. The image formed can be used as an identifying mark, particulary as a security marking for goods, packages, documents or identification cards.

Title: Armoured finger protector
Inventor: LAMBERT FRANK HENRY
IPC: A61B19/04
Filed: 1991-09-04
Abstract: A protector to be worn on a finger by surgeons and doctors, to prevent cuts or needle stab wounds during surgical procedures. comprises a tube closed at one end and formed by one or more strip members (1, 2) in helical configuration. The strip member is of such cross section, e.g. channel section, and is so positioned that adjacent edges of adjacent turns of the helix interlock to prevent the turns separating axially but allowing a limited amount of axial movement. Thus when the protector is worn, the finger can be bent to a limited extent without the adjacent turns separating. Preferably the transverse cross section of the tip of the protector is assymmetric with a portion of the circumference of larger radius of curvature than the remainder of the circumference to provide a flattened tip, thereby improving the grip of the protected fingers. The strip member may be of metal, e.g. stainless steel, or of plastics material <IMAGE>

Title: The removal in aircraft of components from fluid mixtures
Inventor: CASSIDY RONALD FREDERICK
IPC: B01J20/34
Filed: 1992-06-01
Abstract: The removal of components from fluid mixtures in aircraft utilizes an adsorbent bed which is regenerated by passing dry ambient air through the bed when the aircraft reaches a height at which such air is available. The dry ambient air passes through inlet 13 to by-pass 15 and thence to supply line 22 for the aircraft. Some of this air enters the outlet 12 for dry air leaving adsorbent bed 10 and causes ball 18 to close the outlet, while some of the dry ambient air passes through passage 20 and orifice 21 to reduce the pressure of the air to ambient air pressure and thus desorb bed 10. Water is removed from oil in a similar system in which the adsorbent bed (55, Fig. 4) is surrounded by a semi-permeable film (56, Fig. 4) which allows water to pass into the bed. Odours are removed from air by adsorption in a similar bed, in the absence of said film. <IMAGE>
