Title: Printing method
Inventor: LOFFLER GERHARD
IPC: B41F21/00
Filed: 1995-01-09
Abstract: The method, which is suitable for a sheet-fed offset printing machine in which damping, cooling or drying of the work may result in changes in the sheet dimensions, automatically regulates or controls such changes. Sensors are arranged both upstream and downstream of a treatment unit, eg a damping or cooling unit, and sensor signals are used to control the unit in such a way as to regulate the changes in sheet dimensions. In an example, the contraction of a sheet is measured due to drying, and the drying, or the sheet feed speed, is controlled accordingly.

Patent GB-2299667-A (GB)
Title: Formation density measurement apparatus and method
Inventor: SPROSS RONALD L
IPC: G01V5/12
Filed: 1994-12-07
Abstract: A method and apparatus (10) for determining at least one characteristic of a formation is provided which includes storing a plurality of counts received from both a long space radiation detector (12) and a short space radiation detector (14). The counts are detected during a plurality of short duration time periods which are brief compared to rotary drilling speed. A count rate mean is determined and used to sort each of the plurality of count measurements into one of at least three bins. Count information accumulated in at least one of the bins is used to calculate a corrected density. A short space collimator (20) enhances the count rate of singly scattered gamma rays detected by the short space detector (14) and blocks gamma rays from the formation radially outwardly of the short space detector (14) to improve spine-rib correction characteristics for relatively short standoffs. The method of sorting the plurality of short duration time period measurements improves the accuracy for short standoffs to larger standoffs.

Title: Watering device with water-expandable vent closure
Inventor: O'HARA BRIAN
IPC: A01G27/00
Filed: 1997-05-01
Abstract: An automatic plant watering device 1 has an expandable closure member 6 located in an air inlet 9 of a water container 2, and a water outlet 4. The material of the closure member 6 expands upon wetting, and contracts as it dries out, and may comprise adhered non-woven cellulose fibres. In use, the container 2 is filled with water and the closure member 6 is wetted, closing the air inlet 5, and, as air cannot enter the container 2, the water in the container 2 is retained. As the closure member 6 dries, it contracts, allowing air to enter the container, which allows water to discharge into the soil through the water outlet 4. Discharge may be further delayed by use of an open top chamber 12 filled with water, the water in which must first evaporate away before the closure member 6 can dry out. The device may be a kit for attaching to a normal bottle (fig 4). The device may be used as a trigger for the discharge of a larger, part filled water container, raising the water level of the larger container above the level of a siphon tube, effecting complete discharge of the larger container (fig 3), possibly for drip irrigation in a greenhouse.

Title: Detecting and analysing submicron particles
Inventor: CARR ROBERT JEFFREY GEDDES
IPC: G01N21/55
Filed: 1997-06-13
Abstract: A system for the single particle detection of submicron structures such as biological molecules and viruses utilises an optically transparent substrate 1 coated with a thin film of metal 2 illuminated with an optical beam 3 incident at or close to critical or SPR angle. Part of the beam propagates along the metal surface exciting plasmons in the metal film. These plasmons define a measurement zone from which submicron particles 6 contained in a sample placed in contact with the metal film scatter light. This scattered light is detected 9 in the far field at a normal or high angle to the plane of the metal film 2. The apparatus can be configured in a flow cytometric or optical microscope configuration.

Title: Foot orthosis and methods for moulding it
Inventor: ROTHSCHILD VERNON R
IPC: A61F5/01

Abstract: A natural foot orthosis 2 for controlling drop foot comprises a rigid support sructure of thermoformable plastic material for holding and supporting the foot, such structure being reinforced in predetermined areas with additional thermoformable plastic, such as thermoplastic strip 14, to provide extra support in those areas. The material may particularly be an ethylene-propylene copolymer. The orthosis may be made by forming a positive mould of the foot etc., positioning thermoformable material at predetermined locations on the mould where increased support for the orthosis is required, wrapping a thermoformable plastic sheet therearound and vacuum sealing around the mould etc. to combine said material and said sheet. Alternatively, predetermined reinforcement locations may be formed in the mould itself where areas of increased thickness of the orthosis are required, followed by the injection of thermoformable plastic material into the mould to form the orthosis.
