Abstract: A hologram surface to express a phase distribution, a visual field in which a solid image can be seen; and a stereoscopic display limit are set in a virtual space.  A target to be stereoscopically displayed is subsequently expressed in the virtual space by a set of micro polygons.  A plurality of slice planes which are parallel with the horizontal plane are set into the virtual space including the target.  The line segments which intersect the polygons are obtained every slice plane.  The detected line segment is divided or clipped as necessary and is finally divided into the portion which can be always seen from the whole region of the visual field and a portion which is obstructed by another line segment and can be seen from only a part of the visual field, thereby extracting the line segment.  In the calculation of a phase distribution, sampling points are set onto the extracted line segment, a 1-dimensional hologram phase distribution on the hologram surface is calculated every sampling points, and the calculated 1-dimensional hologram phase distributions are added every same slice plane.

Title: Infusion system with multichamber implantable access device
Inventor: HAUSER JEAN-LUC
IPC: A61M39/02
Filed: 1993-04-28
Abstract: A perfusion system comprising an implantable access device with two separate chambers (10, 12) accessed via a septum (16, 18), said chambers being arranged one above the other so that when the infusion or sampling needle is inserted into the lower chamber (10) by passing it through the respective septum (16), said needle also passes through the septum (18) of the upper chamber (12). The system further comprises an infusion device consisting of two rigidly connected parallel needles (36, 38) having different lengths, such that when the longer needle (38) is inserted into the lower chamber, the shorter needle (36) is also inserted into the other chamber. The infusion device with two rigidly connected needles avoids any danger of tearing which may lead to extravasation.
Patent CA-2114824-A1 (CA)
Inventor: RAYNER RICHARD W
IPC: E04D13/17
Filed: 1994-02-01
Abstract: A tarpaulin covering system for protecting a pile of material having an array of folded tubular vents connected to a tarpaulin to assist a weighting system on the tarpaulin in the prevention of aerodynamic lift.  The vents remain in a folded state when the air pressure between the tarpaulin and the pile of material is minimal.          During a period of increased air pressure, the vents in the area of increased air pressure open allowing for the escape of the entrapped air.  The venting system prevents a protective tarpaulin from being lifted off the surface of the material pile which may cause damage to the tarpaulin resulting in an decrease in the overall integrity of the protective tarpaulin system.

Title: Electromechanical thermostatic mixing valve
Inventor: TSUTSUI OSAMU
IPC: F16K31/70
Filed: 1993-07-19
Abstract: ABSTRACT           An electromechanically controlled thermostatic mixing valve (10) comprises a movable mixing valve member (114) resiliently held between a temperature responsive coiled spring (132) and a bias spring (134).   The temperature responsive spring is made of a material such as a shape memory alloy (SMA) having a modulus of elasticity that varies with temperature. The bias spring is supported by an electric drive (46) controlled by an electric control circuit (32) to adjust the preload on the bias spring.   In contrast to the bias spring which is subjected to deformation from its free state to its fully compressed state, the SMA spring is held in such a manner that it is subjected to a limited strain throughout the stroke of the valve member. As a result, premature fatigue of the SMA spring is avoided. Transient fluctuation in water temperature is primarily compensated for by a mechanical feedback control performed by the SMA spring.  Any persistent offset of temperature is compensated for by electrical feedback control carried out by the electrical control circuit that adjust the preload on the bias spring preload such that the actual water temperature is brought to the desired temperature.

Title: Method and Apparatus for the Production of Mineral Wool, and Mineral Wool Thereby Produced
Inventor: BATTIGELLI JEAN
IPC: B28B1/00
Filed: 1992-08-20
Abstract: Mineral material, particularly of the basalt type, is fiberized by internal centrifuging in a spinner (1') having a peripheral wall (19) with a multiplicity of orifices through which the melt may emanate into the environment where a hot gas blast attenuates the melt cones emanating from the orifices to fibers. As such mineral material has a high melting point or liquidus temperature, and low viscosity at the liquidus temperature, a high proportion of unfiberized particles is likely to be produced. However, the production of mineral wool with good fiber fineness and largely free of unfiberized particles surprisingly is possible if the cone lengths and the configuration of the gas flows generated around the spinner are such that the majority of the filament forming cones emanating from the spinner orifices intersect the isotherm corresponding to a viscosity of 100 poises, or otherwise reach into a zone cooled down to a temperature corresponding to a viscosity of more than 100 poises. In practice, such a configuration of the gas flows is produced by an outer annular blower (24) complementing the external annular burner (13) which produces jets of cool air so as to bring low-temperature isotherms in close vicinity of the peripheral wall (19) of the spinner (1') where the tips of the cones reach into such cool zone so as to increase the viscosity at the tip of the cones to avoid breakage of the filament to be attenuated.

IPC: A61K47/48
Filed: 1994-05-03
Abstract: Abstract of the Disclosure Provided herein are carbohydrate complement-modified bifunctional glycoproteins,  and their use  in tumor-selective  therapy.    The  bifunctional  glycoproteins comprise a first component that specifically binds to a tumor-specific antigen and a second component having enzymic activity by means of which a non-toxic prodrug is cleaved  into  a  cytotoxic  drug.    The  carbohydrate complement comprises at least one exposed carbohydrate residue selected from the group consisting of mannose, galactose, N-acetylglucosamine, lactose and fucose.  The modified carbohydrate complement contributes to increased relative concentration of the glycoproteins at the site of the tumor, and enhanced clearance from the general circulation and non-tumor sites.

Title: Sample temperature control system
Inventor: SHEN ANTHONY P
IPC: G05D23/20
Filed: 1994-05-19
Abstract: The system has a thermal unit and a control unit. The thermal unit has an insulation layer enclosing a space for biological or biochemical samples in a container such as a Linbro multiwell plate. The thermal unit has a series of windows above and below the container for viewing and backlighting the sample. The thermal unit has a conductive cage about the space to conduct thermal energy and even out the temperature in the space and has two thermal electric devices and fans abutting the cage out side the space to act as temperature sources. There is a temperature sensor in the space. The system is powered by a control unit that converts and regulates voltage and allows for the selection and viewing of a desired temperature and the viewing of the actual temperature in the space. The control unit has a controller that determines the difference between the actual and set temperature and a bridge that switches the polarity of the voltage to the thermal electric devices to allow for heating and cooling of the space to the desired temperature. The control unit can employ digital control with a dedicated microprocessor, or computer control to implement and track temperature sequences. The thermal unit may be disconnected from the control unit to allow the control unit to be used with different thermal units, or the control unit may power and control multiple thermal units at the same time. The thermal unit is dimensioned to fit within and is not integrated with a microscope. This allows the microscope to be used for other purposes while the thermal unit is in a temperature cycle without breaking the temperature cycle to place the thermal unit in the microscope for viewing, and later removing the thermal unit.
