IPC: G01B7/02
Filed: 1997-07-22
Abstract: A method and apparatus for supporting a patient on a mattress. The apparatus includes a mattress which has at least one controlled release chamber with a top face and a bottom face. A flexible film of a thin metal foil is linked to the top face, while at least one impedance varying device is linked to the bottom face of the chamber. The impedance varying device is an integral part of a measuring electronic bridge. Changes in the impedance as a result of movement of the top face with respect to the bottom face activates a servo control which increases or decreases the inflation pressure within the chamber to make certain that the distance between the top face and the bottom face of the chamber is maintained at a predetermined distance. The method of this invention includes the steps of providing a mattress having at least one closed or controlled release chamber having a top face and a bottom face, providing a measurement device which includes a flexible film of a thin metal foil linked to the top face of the chamber and cooperating with at least one impedance varying element linked to the bottom face of the chamber, the impedance varying element being integral with a measuring electronic bridge, and measuring spacing between the top face and the bottom face to provide control of the supporting action of the mattress as a function of the patient's morphology and position on the mattress.

IPC: B23C5/10
Filed: 1999-01-22
Abstract: A ball nose cutting tool for mounting within a shank-receiving socket of a powered rotatable spindle. The tool includes an elongate and cylindrical shaped tool holder for insertion within the socket of the spindle and a generally rounded upper end. A plurality of insert receiving cavities are formed within the upper end of the tool and a plurality of insert bits are seatingly engaged within the individual insert cavities via threaded openings which are formed in both planar inner side walls defining the cavities and the seatingly engaging drill bits for receiving a screw fastener. An arcuate and curved cutting edge extends from opposite ends of the planar bottom surface and planar end surface and defines a cutting zone extending from the outer periphery to the center of the tool holder. The cutting edges of the arrayed inserts contact one another at the center of the tool holder in a level fashion so that equal cutting forces are applied during high-speed cutting by the tool and equal wear occurs along each of the cutting edges.

Title: Homogeneous preformulations containing high concentrations of steroids, for producing low-dose solid and semi-solid pharmaceutical preparations
Inventor: DITTGEN MICHAEL
IPC: A61K9/16
Filed: 1997-12-15
Abstract: The invention relates to homogeneous preformulations containing high concentrations of steroids which are suitable for producing low-dose solid and semi-solid pharmaceutical preparations with a steroid concentration of between 0.001 and 1 weight percent. Said preformulations are obtained by evaporating the dispersing agent containing the steroidal active ingredient from a suspension containing the usual pharmaceutical additives. To this end, a spray mist is produced in which the average drop diameter is greater than the average diameter of the additive particles, and the maximum grain size of the dried particles of the steroidal preformulation is increased by less than 30 % in relation to the grain size of the additive. Said preformulations are characterised by their homogenity and resistance to demixing, whereby the steroidal active ingredient is finely dispersed and integrally bonded to the additive. Surprinsingly it was discovered that these types of steroidal preformulations, in comparison with conventional methods, can be processed without difficulty into low-dose pharmaceutical preparations with very good homogeneity and active ingredient stability. The method for producing homogeneous steroid preformulations for low-dose solid and semi-solid pharmaceutical preparations with a steroid concentration of between 0.001 and 1 weight percent stands out among other things by the fact that the active ingredient and additive particles from the atomized suspension are not dried one next to the other. The choice of processing conditions during atomization makes it possible for practically all the active ingredient to be bonded integrally to the additive.

Abstract: The present invention relates to a medicament container for storing a liquid medicament, such as insulin, the container comprising a distal and a proximal end portion and a wall, at least two opposite portions of the wall being of a polymer material. The thickness of the polymer wall portions is between 0.3 mm and 3 mm, and the light transmission through the polymer wall portions at 400 nm are at least 25 %. The polymer wall portions are of a material comprising at least 70 % by weight of a copolymer material composed of aliphatic cyclic or bicyclic hydrocarbons with 5 to 7 membered ring or rings and ethylene or propylene, the material having a glass transition temperature above 50 ~C, and a density of 0.95 g/cm3 or more. The container of the polymer material is substantially inert to the medicament, and furthermore, the container is transparent, whereby it is possible visually to inspect the content of the container to make sure that the medicament is not crystallised or polymerised.  Furthermore, the walls of the container provide a good barrier against m-cresol/phenol/benzyl alcohol preservatives and water, respectively. The invention also relates to the use of such medicament container, and a medicament container at least partly filled with medicament.

Title: Stain inhibiting pigment composition
Inventor: SINKO JOHN
IPC: B27K3/52
Filed: 1997-03-13
Abstract: A process of treating wood to reduce the tannin staining of coatings subsequently applied includes the steps of providing a solution of a zirconyl compound in a carrier liquid such as water, applying the solution to a wood surface, and drying the solution. The pore structure of the wood is modified or sealed so that staining of coating compositions applied subsequently over the surface is reduced. The process is particularly beneficial in cases where the coating composition is a clear or a light-colored latex paint, especially white. The preferred zirconyl compound is zirconyl acetate. The treating solution may be modified by addition thereto of a lanthanide compound, especially cerium, to provide UV light protection to a substrate and further by one or more metal cations to impart mildewicidal activity to the composition.

Abstract: The present invention relates to DNA molecules associated with conferring on Mycobacterium tuberculosis an ability to enter mammalian cells. The protein encoded by these DNA molecules are useful in vaccines to prevent infection by Mycobacterium tuberculosis, while the antibodies raised against this protein can be employed in passively immunizing those already infected by the organism. Both these proteins and antibodies may be utilized in diagnostic assays to detect Mycobacterium tuberculosis in tissue or bodily fluids. The protein of the present invention can be associated with various other therapeutic materials, for administration to mammals, particularly humans, to achieve uptake of those materials by such cells.
