Title: Server system for rubberized sheets
Inventor: CHAPLIN GREGORY D
IPC: B65H23/198
Filed: 1989-12-12
Abstract: ABSTRACT OF THE DISCLOSURE           A system and apparatus for accurately delivering rubberized sheets from a supply roll of stock material containing an intervening liner to an assembly station for subsequent assembling into an air spring or similar article of manufacture by eliminating the heretofore formation of a "free loop" therein.  The supply roll and a liner take-up reel are rotatably mounted on a carriage transversely movable with respect to the longitudinal motion of the stock material.  A hugger device has a plurality of timing belts which frictionally engage the liner at the take-up reel and winds the liner onto the reel at a constant linear speed regardless of the diameter of the reel and collected liner to move the rubberized sheet fit a controlled rate toward the assembly station.  The motion profile of the timing belts is controlled by a servo drive motor and the belts engage an arcuate portion of the circumference of the take-up reel to provide positive frictional drive engagement therewith. The carriage is moved along a pair of tracks by a ballscrew mechanism for bringing the cartridges of stock material and take-up reel into position with the timing belts and assembly station.  An optical edge detection device and encoder, in conjunction with a motion controller, accurately control and regulate the system.

Title: Pressure regulator
Inventor: ESOLA JOHN L
IPC: G05D16/06
Filed: 1990-04-18
Abstract: A diaphragm actuated pressure regulator is provided having a molded contoured diaphragm capable of operation in the upper portion of the diaphragm's deflection stroke without experiencing material deformation and thereby preserving the precision of the diaphragm's response to pressure fluctuations. The pressure regulator includes a curved lever arm for transmitting the deflection of the diaphragm to a displacement of a valve pad which regulates the flow of gas from an inlet through an orifice restriction to an outlet. The lever fulcrum is located in the throat area of the pressure regulator and supported by a guide to provide a high lever ratio which enables a relatively small diaphragm to generate a relatively high valve closing force, In a preferred embodiment of the invention the diaphragm includes an O-ring shaped circumference which is secured between the upper assembly and the lower case of the pressure regulator thereby insuring an air tight seal without the need for an additional gasket or sealant material.

Inventor: ROTSAERT HENRI L
IPC: A61C5/77
Filed: 1990-05-11
Abstract: A method for the manufacture of artificial teeth, either replacement of whole teeth or crowns, whereby a tooth is produced by machining from a layered block (20) of synthetic plastics materials, the layers (34, 36, 38, 40) being of predetermined carrying colour (hue), chro-ma, value and translucency to stimulate the pulp, den-tine and enamel layers in a real tooth, thereby providing an artificial tooth with the distribution and depth of co-lour of a real tooth. The process provides for varying the tooth colour by milling the tooth from a different section of the layered block to vary the thicknesses of the layers, at least at the labial, menial, distal and occlusal surfaces, so as to obtain a custom tooth matched very closely to a patient's real tooth colour and pattern. The invention permits the manufacture of an artificial tooth from mate-rials with a hardness closely matching that of a real tooth to provide similar wear properties.

Title: Nozzle shut-off valve
Inventor: DINERMAN ALEX
IPC: B29C45/23

Abstract: A nozzle shut-off valve (21) for the plastification system of an injection molding machine (10). The valve (21) includes a cylindrical inner body member (52) that has axially spaced inlet (54) and outlet (58) passageways. Inclined passageways (64, 66, 68, 70) extend from the inlet (54) and outlet (58) passageways to the outer surface of the inner body member (52) to terminate in spaced openings (72, 74, 76, 78) on the periphery of the inner body member (52). A tubular outer member (84) is provided with at least one recess (86, 88) or depression on its inner surface, the recess (86, 88) having a length sufficient to provide communication between a pair of the spaced peripheral openings (72, 78) in the inner body member (52) when the recess (86) is positioned in overlying relationship with the respective openings (72, 78). Rotation or translation of the tubular outer member (84) relative to the inner body member (52) shifts the recess (86) out of registration with the respective peripheral openings (72, 78) to thereby prevent flow of material through the valve (21).
