Patent CA-2037213-A1 (CA)
Inventor: NOZAKI MASAHIRO
IPC: B60R13/06
Filed: 1991-02-27
Abstract: A method for forming a molded portion composed of solid rubber onto an end of an extruded weather strip having a base portion composed of solid rubber and a lip-shaped sealing portion composed of sponge rubber and extending from the base portion.  The method includes the steps of inserting the end of the extruded weather strip into a cavity of a mold, the cavity having a cross-sectional shape identical with that of the end of the extruded weather strip.  The method further includes injecting a molding material into the cavity from a gate of the mold while throttling the molding material flowing to the end of the lip-shaped sealing portion of the extruded weather strip by a protruding portion protruding into a passageway of the cavity leading to the end of the lip-shaped sealing portion of the extruded weather strip at a position close thereto.  This causes the pressure of the molding material acting on the end of the lip-shaped sealing portion of the extruded weather strip to be smaller than that of the molding material acting on an end of the base portion of the extruded weather strip.

Title: Dielectric measuring apparatus for determining oil and water mixtures in a well borehole
Inventor: SINCLAIR PAUL L
IPC: E21B47/10
Filed: 1991-06-19
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for measuring a mixture of oil and water in a well borehole is set forth. The measurement is a measurement of mixture dielectric constant obtained by exposing a pair of windows to the mixture of well borehole liquids. Each window is formed in coaxial cable portions having cuts in the respective surrounding ground sheaths thereof wherein the sheaths are positioned so that the windows are adjacent and parallel. The two windows form a gap which may be approximately three times wider than the windows formed in the sheath. A signal generator drives the system at a specified voltage and frequency, and changes in signal coupled between the cables are measured where the changes derive from changes in the dielectric constant of the mixture of oil and water coupled in the circuit.

Title: High resolution camera with hardware data compaction
Inventor: BAIRD RANDY K
IPC: H04N5/225
Filed: 1991-09-09
Abstract: A high resolution object handling system serves as an object discrimination - identification by creating an object silhouette. The objects are siagulated on a conveyor and scanned by a linear array of CCD units (2048 pixels per inch) at a scan rate of 10 MHz. Pixel transitions corresponding to object edge points are converted to a single count value from a counter which is synchronized with the scanner. A microprocessor with a first in, first out buffer memory needs only a capacity to handle the count value rather than all data from the pixels.

Title: Electromagnetic shielding with discontinuous adhesive
Inventor: HOGE WILLIAM C JR
IPC: H05K9/00
Filed: 1991-10-25
Abstract: A shield blocks passage of electromagnetic energy through a seam of indefinite length between conductive elements and is adhesively attached to at least one of the elements. A preferably non-conductive adhesive is disposed on a conductive surface of a seal in a discontinuous pattern along the length of the seam, defining areas of 5-40% adhesive for physically attaching the conductive surface, separated by 60-95% exposed areas for direct electrical contact. The seal can include a compressible body or can be defined by a conductive sheet, for example a fabric provided with a plating or other conductive coating. The areas of adhesive preferably define longitudinally non-overlapping inclined lines extending laterally across the seam. A release liner can removably attach to the adhesive. Tn a preferred embodiment the conductive surface is the surface of a compressible seal body, such as a conductive sheath on a compressible core. A conductive path extends without interruption along the length of the seam and across the lateral width of the seam at the adhesive lines, providing improved physical attachment and conductivity characteristics for the shielded seam as a whole.

IPC: B21B21/00
Filed: 1992-07-21
Abstract: ABSTRACT OF THE DISCLOSURE A cold pilger rolling mill includes a reciprocating roll stand and a crank drive connected to the roll stand through connecting rods. The crank drive includes three shafts arranged parallel to each other and spaced apart at equal distances. The middle shaft is a crank shaft connected through crank pins with the connecting rod. A main weight for balancing half of the inertia forces of the roll stand is arranged eccentrically relative to the axis of rotation on the crank of the crank pin offset by 180° from the pivot point of the connecting rod. On the two other shafts are arranged two additional weights of equal size which balance the other half of the inertia forces of the roll stand. For a synchronous rotation of the shafts and their weights, the shafts are connected by spur gears meshing with each other in such a manner that the additional weights rotate in opposite directions to the main weight with the same rate of rotation and, at the dead centers of the roll stand, the sum of the main weight and the additional weights acting on the roll stand corresponds to the inertia forces of the roll stand and of any other weights moved with the roll stand.
