Title: Method of making an impression of a dentate human jaw
Inventor: SCHREINEMAKERS JOESEPHUS
IPC: A61K6/90
Filed: 1992-05-15
Abstract: ABSTRACT OF THE DISCLOSURE         A bead of a high-viscosity impression material is applied along the entire edge of an imperforate tray forming a U-shaped recess and an endless edge extending all around the recess and the tray is fitted, before the material cures, over a pa-tient's dental arch with the bead on the edge engaging the de-formed by the patient's mobile mucosa outward of the linear action boundary. The deformed bead of high-viscosity material is cured to form the tray and the cured bead of high-viscosity material into a custom tray which is then filled with a body of a low-viscosity impression material and again pressed over the pa-tient's dental arch to press the cured bead on the tray edge into tight engagement against the mobile mucosa outward of the linear action boundary to form between the tray and the dental arch a substantially closed and generally constant-section chamber hydraulically confining the low-viscosity impression material. The confined low-viscosity material in the chamber is then compressed against the dental arch by pressing the tray toward the arch while mobilizing the mobile mucosa to hydraulically press the confined material into form-fit engagement with the stationary mucosa and tooth and without substantial leakage of the impression material from the chamber and the low-viscosity impression material is cured. Finally the custom tray with the cured low-viscosity material is stripped from the patient's jaw. This method ensures that a very accurate impression of the hard dental structures can be taken and that this impression can subsequently be stripped relatively easily from the jaw being worked on.

Title: Apparatus and process for measuring release rates of bound solutes from binding compositions
Inventor: MILLER MURIEL E
IPC: G01N33/00
Filed: 1992-08-07
Abstract: ABSTRACT OF THE INVENTION       The rate at which adsorbed materials are released from a small sample of a finely divided adsorbing material such as a polymeric adsorbent or ion exchange resin may be determined by confining the sample in a broad, thin configuration between a pair of porous supports, passing an eluting liquid through the porous supports and the sample to elute the adsorbed material, and detecting the amount of adsorbed material which has eluted into the eluting liquid. The accuracy of this measurement is significantly improved where the volume through which the eluting liquid travels from the second porous support to the detector is minimized.

Patent CA-2077832-A1 (CA)
Inventor: COSTANZA DANIEL W
IPC: G03G15/00
Filed: 1992-09-09
Abstract: A single pass ROS system provides a plurality of latent images which may subsequently be developed in different colors. The ROS units are initially aligned so that each color image is precisely registered at the same relative position along the exposed area of a photoreceptor belt. The alignment is accomplished by forming a pair of opposed alignment apertures in the surface of the belt and detecting coincidence or lack of coincidence of signals generated by the beginning and end of each scan line. The skew correction is enabled by rotating an optical component in the ROS system to create the required rotation of the projected scan line so as to correct for the detected skew error caused primarily by belt conicity. Once the initial X and Y-axis alignments are complete, subsequent alignment is maintained through subsequent passes by checking the positions of the previously identified pixels as they advance past additional lead edge apertures formed in the process direction along the belt surface.
Patent CA-2081488-A1 (CA)
Inventor: HOLT WILLIAM J
IPC: B25B23/14
Filed: 1992-10-27
Abstract: Apparatus (10) for measuring and controlling the tensile load on a fastener (F).  The fastener is positioned to connect together two or more components (X) of a workpiece.  A drive unit (12) couples to the fastener to thread it into place.  The fastener exerts a clamping force on the components to connect them together.  The clamping force created by the fastener produces an equal and opposite tensile force on the fastener.          A controller (16) starts and stops operation of the drive unit.  The controller controls the drive unit to thread the fastener into place until it exerts a predetermined amount of clamping force on the components.  A test unit (18) generates ultrasonic waves and transmits them lengthwise through the fastener.  The transit time of the waves through the fastener is then measured.  The transit time of the waves is a function of the tensile force on the fastener and, in turn, a function of the clamping force exerted by the fastener.

Inventor: DARSEY RALPH J
IPC: G02B6/46
Filed: 1993-06-18
Abstract: An optical fiber package of this invention applies a friction enhancing material to the smooth surface of a bobbin or mandrel onto which the optical fiber is wound. The friction enhancing material adheres the initial layer of fiber to the smooth surface of the bobbin, thereby eliminating the need for an independent base structure for establishing and maintaining a winding path for the fiber. Furthermore, the friction enhancing material prevents the lateral movement at initial layer of fiber relative to the bobbin. In accordance with the preset invention, the friction enhancing material is preferably a plastic material such as room temperature vulcanized (RTV) silicones and Styrene Butadiene Rubber (SBR) or the like. In addition, the optical fiber package of this invention may combine the use of both a friction enhancing material between the initial fiber layer and the bobbin, as well as an adhesive material coating applied along the length of the optical fiber. Accordingly, a stable package of elongated optical fiber strand material is established which may be used in situations or environments requiring rapid payout of the fiber without adversely effecting either the physical or the communicational properties of the fiber.
