IPC: A61K31/7042
Filed: 1985-08-07
Abstract: Dehydrated liposomes are prepared by drying liposome preparations under reduced pressure in the presence of one or more protective sugars, e.g., the disaccharides trehalose and sucrose. Preferably, the protective sugars are present at both the inside and outside surfaces of the liposome membranes. Freezing of the liposome preparation prior to dehydration is optional. Alternatively, the protective sugar can be omitted if : (1) the liposomes are of the type which have multiple lipid layers ; (2) the dehydration is done without prior freezing ; (3) the dehydration is performed to an end point which results in sufficient water being left in the preparation (e.g., at least 12 moles water/mole liped) so that the integrity of a substantial portion of the multiple lipid layers is retained upon rehydration. Concentration gradients capable of generating transmembrane potentials can be created across the liposome membranes either before or after dehydration, and the transmembrane potentials resulting from these gradients can be used to load charged materials, e.g., drugs, into the liposomes.

Patent PT-91047-B (PT)
Inventor: MUELLER KARL F
IPC: C08G18/81
Filed: 1989-07-03
Abstract: This invention describes polymers which are obtained by copolymerization of 15-85 wt % N,N-dimethylacrylamide with about 15-85 % of a fluorinated monomer such as perfluoroalkyl-alkylene acrylate or -methacrylate with from 3 to 25 fluorine-atoms and optionally, 0-50 wt % other acrylates or methacrylates and 0-20 wt %, but not more than 5 mol % of a polyvinyl functional crosslinking agent. These polymers are machinable in the dry state and form clear hydrogels with about 25-75 wt % water content and which possess oxygen-permeabilities 3-7 times higher than conventional hydrogels of similar water content. In the absence of crosslinking, the novel polymers are plasticized by water, forming clear hydroplastics with 30-70 wt % water content. The crosslinked polymers are especially useful for fabricating contact lenses for extended wear by either cutting and polishing a xerogel button, or by spin casting or direct molding in bulk or in solution.

Title: Examination arrangement comprising a radiation source and a radiation detector
Inventor: MEEK G J
IPC: H05G1/02
Filed: 1978-06-13
Abstract: Tomography apparatus for plane-parallel tomography, comprising an X-ray tube and a detector which are mechanically connected to each other by a column which consists of two parts. The linear movement of the X-ray tube is obtained by displacing the two parts into or out of each other during the pivoting movement of the column. However, the use of conventional servo control arrangements for obtaining the inward or outward telescoping movement involves a position error of the X-ray tube approximately directly proportional to the speed of the inward or outward telescoping movement of the column parts. This position error is eliminated by adding a correction signal to the control signal of the servo control arrangement, this correction signal being proportional to the speed of the inward or outward telescoping movement. <IMAGE>

Title: Portable air-filtration plant with filters which are self- cleaning through the use of pulsed jets
Inventor: BRENHOLT D L
IPC: B01D46/24
Filed: 1980-03-17
Abstract: The present invention concerns a portable air-filtration plant with filters which, thanks to the use of pulsed jets, are self-cleaning. This air-filtration plant 10 comprises a housing with a first dividing wall 50 which splits the interior of the housing into a first basically vertical long chamber 48 and a second basically horizontal long chamber 46. The dividing wall is situated in an oblique plane forming angles with the longitudinal axes of the first and second chambers, and is provided with an opening 52 which enables medium communication to be made between the first and second chambers. A fan 130 is arranged in the housing to draw in air through the housing from an inlet 120 for dust-laden air to an outlet for clean air. A filter 86 is mounted in the housing, designed to filter the air passing through the said opening in the dividing wall. An air valve for back pulses is fitted in the housing in order to direct a pulse of cleaning air to the filter so as to clear any dust or fluff which has collected on it. An electrical control circuit is arranged to actuate the back-pulse air valve and is connected to a suitable compressed-air source. The air-flow path through the air-cleaning plant is such that removal of dust from the filter when the back-pulse of air is introduced into same will be facilitated, whereby the said dust is collected conveniently in a dust-collection vessel 18. The air- cleaning plant is compact and has a low centre of gravity, making it easy to transport from one industrial site to another. <IMAGE>

The inner channels can be united in groups of one or more channels, in which the inside air circulates. The catcher can also be used as a heat exchanger, whereby air is sucked into the structure through the interior channel system.

Title: Totaliser for hydraulic crane scale
Inventor: KARLSSON EINAR
IPC: G01G23/18
Filed: 1983-11-24
Abstract: Weight totaliser for hydraulic crane scale comprising a piston/cylinder device whose piston is controlled by a spring to be held in and returned to a starting position and is connected to an indicator integrated in the totaliser. Said piston/cylinder device is hydraulically connected to the crane scale via a non-return valve that normally holds said connection closed but can be controlled, preferably remote controlled, for opening of the same, thereby allowing hydraulic oil from the crane scale when laden to displace the piston and thereby move the indicator to an angle corresponding to the weight of the load suspended in the crane scale. Standard totalisers of this type have a source of measurement error that is added to each weighing operation. To eliminate this source of error and also make taring possible, a gear segment (12) that works together with a gear rack and can be actuated by one of the pistons (8) is designed to transfer piston movement caused by hydraulic oil to the indicator (22). The piston segment, together with the gear rack, can be set to a starting position in relation to the piston and is connected to a shaft (13) bearing the indicator (22) via a freewheel (14), which turns the shaft (13) and thereby the indicator (22) during piston movement caused by hydraulic oil, but releases the shaft (13) from the piston segment (12) during piston movement to the starting position caused by the spring. The shaft (13) bearing the indicator (22) is controlled by brake force from a brake assembly (15-18, 20) to prevent it from turning during the piston's return movement to the starting position after the non-return valve is closed.<IMAGE>
