Granted: 1996-11-05
Abstract: In a device for producing granules or tablets  from  fluid materi-als, the material is fed to the press-slot between a rotative hollow cylin-der with an inner toothing and a press-cylinder with an outer toothing that engages said inner toothing.  Bores extend from the  bottom of the teeth of the inner toothing of the hollow cylinder up to its outer side, the material is pressed through these bores when the hollow  cylinder engages the press-cylinder  and is laid as tablets or granules on a cool-ing  surface.  At least  one part of the outer  circumference  of the hollow cylinder  remote from the cooling surface  is surrounded by  a  heating shell.  Outside the heating shell (3), spaced  apart from it, is arranged another shell (5), in such a  way that  between the  heating shell (3) and the other shell  (5), a  waste  gas shaft (4) is formed,  in communication with a suction nozzle (6) for the gases that emanate from  the material.

Abstract: A method for prescribing a prism factor for eyeglasses for substantially correcting vertical and/or horizontal diplopia or double vision problems, which includes having a patient positioned for gazing at a target image while holding their head in a substantially fixed position, and then closing their affected eye for a period of time, whereafter they are instructed to open the affected eye and immediately report upon where a double image occurs upon a measurement grid associated with the target image continuing to be observed by their other eye, for permitting a prism factor to be prescribed relative to the measured distance between the target and double image created by the defective eye.       The minimum necessary prism factor for correcting the vision of the defective eye to provide for merger of the target image observed by the other eye with that of the defective eye upon opening, permits maximization of the involvement of the eye muscles of the defective eye in combination with the prescribed prism for substantially extending the range of correction of the diplopia problem.

Title: Fluid control nozzle for conduit cleaner
Inventor: SALECKER ROY W
IPC: B08B9/045
Filed: 1993-09-20
Granted: 1999-01-26
Abstract: A power unit for a conduit cleaner. The conduit cleaner has a motor with a housing carrying a shaft that is rotatable about an axis. The motor operates in response to the introduction of a pressurized fluid. The housing has inlets for admitting pressurized fluid and an outlet to permit the discharge thereof. A nozzle is connected to the housing and is configured to direct fluid from a pressurizedsupply to the housing inlet and direct fluid discharged from the outlet out of the power unit. The nozzle has a substantially cylindrical outer surface. In one form, the nozzle does not project beyond the cylindrical outer surface. Accordingly, acompact unit can be made according to the present invention. The absence of radially projecting structure also avoids protrusions that may intercept roots or other foreign matter within a conduit and thereby interrupt free movement of theconduit cleaner through a conduit.

IPC: B23Q16/08
Filed: 1995-08-10
Granted: 1999-11-23
Abstract: The fastening of two parts (1 and 3) to one another, e.g. of a tool or workpiece, on a holder provides that the two parts (1 and 3) to be fastened together have adjoining fitting areas (4 and 5) when in use and are braced against one another by fastening means, e.g. a single fixing screw (2), extending diagonally or at right angles to the contact plane of these fitting areas (4 and 5). In this cask in addition to the fitting areas (4 and 5) fixing the reciprocal axial position in Z direction, fitting projections (9) are provided on the one part and fitting recesses (10) on the other part which prevent the parts (1 and 3) connected and braced with one another from shifting diagonally to the fastening means within the contact plane of fitting areas (4 and 5) and which center the two parts (1 and 3) diagonally to this contact plane in X and Y direction so as to fit accurately. The fitting projections (9) are thereby on an area (il) which can deviate elastically, or is flexible, in axial direction against a deformation force which can be applied by the screw (2), of the part (1 or 3) on which they are located, so that the fitting projections (9) engage so as to fit accurately in the fitting recesses (10) before the fitting areas (4 and 5) come in contact. By tightening the fastening means more, fitting areas (4 and 5) then also come into reciprocal contact without the need for an additional part for adjusting or centering in X and Y direction.

Abstract: Nonionic surfactants comprising a mixture of fatty acid esters of sorbitol and sorbitol anhydrides comprising predominantly the mono, di-or tri ester condensed with approximately 15 or more moles of an alkylene oxide in combination with an effective defoamer and a water soluble diluent form surprisingly useful and effective low foatning rinse agent composition or concentrate. The rinse agent can achieve adequate sheeting in cotnmon aqueous rinses at typical rinse temperatures at a concentration of the nonionic sorbitan ester in water at concentrations about 500 parts of the fully formulated rinse agent per million parts of water. The rinse agents can be used in a rinse cycle in common warewashing machines after washing with commonly available warewashing compositions. The rinse agents can take the form of thickened pourable or semi-pourable aqueous liquids or cast solid materials packaged within a disposable wrapper, capsule or other package. The preferred form of the rinse agent is a pourable or pumpable aqueous concentrate. The uniqueness of the invention relates to the fact that all components are not expected to be active as sheeting, agents and are approved as food additives thereby eliminating any health concerns associated with residual deposits of the compositions on cleaned water.
