Granted: 1988-01-27
Abstract: Powdered dental material of a sintered mixture of calcium aluminum fluorosilicate glass and precious metals (or alloys thereof with each other or with up to 40% non-precious metals), which may optionally contain polycarboxylic acid and/or a chelating agent and/or further powdered precious metal. The dental material can be prepared by sintering a mixture of the glass and the precious metal at a temperature greater than 600 DEG  C., grinding the sintered product to a powder and admixing the optional further components. Use of the self-hardening glass ionomer cements for dental filling purposes gives fillings having excellent resistance to wear, most notably at the edges and corners in the molar region.

Abstract: A prosthetic device for the relief of high intraocular pressures associated with glaucoma is shown. The device includes a limp reservoir adapted to be worn against or within the eye wall, a conduit leading from the reservoir to the anterior chamber of the eye, and means for communicating the reservoir with liquid-receptive tissue. Unidirectional flow means, such as a check valve, is employed to prevent back-flow of liquid into the anterior chamber. When the reservoir is periodically compressed, aqueous humor collected in the reservoir is expelled into liquid-receptive tissue where it is absorbed or is passed to the venous system.

Abstract: The invention relates to a process for manufacturing crystalline alumina from aluminum hydroxide which after further conventional treatment is advantageously suitable for ceramic and refractory purposes or as a lapping and polishing agent. The process is such that aluminum hydroxide with a Na2O content of </=0.1 wt. % with respect to Al2O3 is subjected either directly or after prior partial dehydration to a thermal treatment above the temperature for transformation to  alpha -Al2O3. The aluminum hydroxide has an addition of an ammonium containing mineralizer made to it, simultaneously in the presence of boron and/or fluorine, in particular an addition of NH4BF4. The product is characterized by way of the essentially isometric shape of the single crystals.

Title: Apparatus for implementing a standardized skin incision
IPC: A61B17/32
Filed: 1986-02-17
Granted: 1993-04-14
Abstract: An apparatus is provided for implementing a standardized skin incision which apparatus includes a housing (14) having a base containing an elongated slot (21). The base is adapted to be held flush against a patient's skin prior to making an incision. The housing (14) has an internal hollow (30) which contains a pivot arm (60) having a first pivotal end and a second end having a cam follower (61). Located within the housing is a cam surface (50) upon which the cam follower (61) of the pivot arm (60) rides. The pivot end of the arm (60) contains a cutting edge (71) and is coupled to the housing such that it is enabled to move transversely while pivoting. The cam surface (50) which is a convoluted surface controls the path of the pivot arm (60) and therefore controls the path of the cutting edge (71) as it enters the slot (21) when triggered. The device produces a standard incision of a given length and a given depth as controlled by the reciprocating pivot point and the cam surface. The device is completely disposable and further possesses the advantage that the cutting edge (71) is always located within the housing (14) except when the unit is triggered where the edge (71) traverses and projects through the slot (21) in the housing (14) for an extremely short period of time. The unit can be fabricated from plastic and sterilized prior to use and hence it is completely disposable.
