Title: 3-epi vitamin d2 compounds and uses thereof
Inventor: REDDY SATYANARAYANA G
IPC: A61P19/08
Filed: 1998-05-15
Abstract: Novel 3-epi vitamin D2 compounds having the orientation of the substituent attached to the carbon at position 3 of the A-ring of vitamin D2 inverted from a beta (.beta.) to an alpha (.alpha.) configuration are described. These compounds were first identified as metabolites of vitamin D2 produced via a novel tissue-specific metabolic pathway which catalyzes the 3-.beta.-hydroxy epimerization of vitamin D2 compounds. The 3-epi vitamin D2 compounds of the present invention can be used as substitutes for natural and synthetic vitamin D.

Abstract: The invention relates to a device for gradual cross-feeding of elongate objects, comprising a stationary support frame (2), which in profile is stepped in at least two sections (1, 1', 1'') which are arranged in separate planes with an upper sliding and supporting surface (8) and a step front edge (4) in the feeding direction, and a feeding arrangement, which is also stepped in profile and has one section less than the number of sections in the support frame and the sections of which each have at least two upper sliding and supporting surfaces (7) extended in the feeding direction and a step front edge (6) in the feeding direction. The upper sliding and supporting surfaces (7) of the feeding arrangement (5) in one section are vertically positioned at a level below the sliding and supporting surfaces (8) of the support frame in the corresponding section but at a level above the sliding and supporting surfaces of the support frame in a subsequent section. The feeding arrangement (5) is reciprocatable by means of a power generating means (11) along the support frame (5) to effect the feeding of the objects by alternating engagement of the objects between the step front edges (4, 6) of the support frame (2) and the feeding arrangement (5). The feeding arrangement (5), as well as the objects, is supported on the supporting surfaces (8) of the support frame (2) and is reciprocatable along these.

Abstract: There is proposed use of microphone recordings of air waves, recorded close to a geophone, to suppress air-wave and surface-wave noise on the geophone. The types of air-wave noise on the geophone may include air-coupled ground roll, air blast, ground-coupled air blast and wind noise. Microphone recordings of air waves are related to ground measurements and geophone disturbances. The air wave may be used to filter the geophone data. Tests on recordings from the Calgary General Hospital implosion on October 4, 1998 indicate success in reducing noise on the geophone data. There is further proposed a geophone with an attached microphone to reduce noise on the geophone data. In addition, a geophone attached to a microphone could be used to reduce ground motion noise on the microphone.

Abstract: An automatic dispenser comprises a receptacle (1) with a vertical back wall (5) and side walls (4) and an inclined front wall (7) with an outlet opening (21) at the bottom and a closing mechanism (3) which at the top has an oblique top plate (11). The closing mechanism (3) is embodied and hung in the receptacle (1) so that in a lowest and highest position it closes the outlet of fodder from the receptacle (1), but in the upper position opens for supply of fodder from the receptacle (1) to a space (23) through a gap (22). A rear edge (19) on the plate (11) scrapes against the back wall (5) during the travel of the closing mechanism, and at the same time the inclination of the plate (11) is altered. Thereby the fodder is pumped in the direction from the back wall (5) towards the front wall (7). It is thus all the time the lowest fodder in the receptacle (1) that is dispensed, and no bridging of thickened fodder occurs. Consequently, the automatic dispenser has a dependent operation, and it can dispense accurate quantities with a minimum of waste.

Abstract: A method and apparatus for the alleviation of an undesirable fluid accumulation in a body area of a patient is provided. The apparatus, or static reaction system has enclosure containing a multiplicity of particles that are pressed against the body area. The shape of the enclosure and the physical qualities of the particles affect the suitability of specific versions of the invention to particular conditions and body areas. Pockets are included in some versions of the enclosure to capture and isolate subsets of the multiplicity of particles. An optional directional flow pattern feature is established by the orientation, sizes and shapes of the optional pockets and thereby affects the rate at which the fluid accumulation is reduced.  Lightweight and flexible materials are used to manufacture various comfortable, transportable and storable models of the invention. The enclosure is optionally constructed with low friction, porous and breathing fabrics and materials to improve patient comfort and patient compliance. The enclosure is pressed, held and/or forced against a selected body area by means of a detachable compression cover, a pneumatic pack, compressive bandaging or wrapping, and made with VELCRO stretch fabric and/or with VELCRO strapping or other suitable means. Certain versions of the invention are applied by a capable and competently trained patient and with reduced need of constant professional supervision.

Abstract: The present invention relates to a heat radiator assembly comprising at least one heat radiator unit which comprises in combination a base and a primary reflector mounted on the base, the primary reflector having an elongated body with side walls (with a parabolic configuration in cross-section) upstanding outwardly from the base and end walls. A high power heating lamp is accommodated within the primary reflector by means of an elongated gap formed between lateral edges of the side walls of the primary reflector adjacent to the base. A secondary reflector having a generally elongated configuration is mounted on the base; it has an inner and an outer surface. The secondary reflector's inner surface faces the elongated gap of the primary reflector and the outer surface faces the base; the secondary reflector is adapted to reflect all lost radiation emitted from the lamp through the gap towards the base, thus facilitating prevention of overheating of the base and increasing efficiency of the heat radiator assembly. The secondary reflector has a concave configuration in cross-section, and the primary and secondary reflectors may be made of tempered gold-anodized aluminum embossed with a pattern facilitating heat radiation efficiency and to strengthen structural integrity of the heat radiator unit.
