Patent CA-2172563-A1 (CA)
Inventor: CHEN ROBERT K
IPC: H04M19/00
Filed: 1996-03-25
Abstract: A subscriber line circuit which truly implements all of the BORSCHT functions and which does not rely on an external ringing generator to provide the ringing voltage when needed is disclosed. This implementation is achieved by recognizing that supervisory and ringing signals occur in some sort of sequence and, therefore, do not have to be generated simultaneously. Based on this recognition, we provide a circuit which truly implements all of the BORSCHT functions and includes a power sectionthat generates each of the supervisory signals, e.g., -48 volts and -24 volts, and alerting signal, e.g., ringing signal, in turn and as required.

Title: Absorbent granular material and process and apparatus for making the absorbent granular material
Inventor: KNAPICK EDWARD G
IPC: C05G3/80
Filed: 1996-05-13
Abstract: A process  is disclosed which utilizes the  "non-papermaking" portion of waste paper to produce a highly absorbent,  essentially fiber-free granule which can be used, for example, as an agricultural chemical carrier. The process maximizes the amount of long (papermaking) fiber sent to the paper machine.     The waste paper is broken up in a hydropulper, and the pulp stock is screened so that papermaking fibers are retained and sent forward to the papermaking process, and the solid material in the reject stream, such as kaolin clay and inorganic materials pass through a flotation clarifier to separate the solids.   The slurry is then dewatered by means of a belt press to form a filter cake. The filter cake then enters a pin mixer where it is broken up into individual granules.  The granules are then dried to a solids content of greater than 95%.

Patent CA-2211824-A1 (CA)
Inventor: KELLY DANIEL FRANCIS
IPC: B21D43/26
Filed: 1997-08-22
Abstract: This invention relates to a device which holds sheet metal up to a brake press stops.    A brake press is a machine for forming metal. They vary from a few tons, to hundreds of tons. The size may also vary from a few feet to many feet in length.    On the back of a brake press there is usually a metal rail the length of the press, mounted one way or another to the machine. This rail is known as a back rail, this is the rail where the stop's are mounted.    The stops are what the material hits when it is pushed into the press, the distance between the stop and the bending point of the top die will be the inside dimension of the bend.    Because the stops are mounted on the rail, when the rail is moved the stops also move. The reason the rail is moved is so the operator can achieve a different size bend. For example, if the operator was forming a half inch bend, and then wished to form an eighteen inch bend, then he would move the back rail out further by seventeen and a half inches. This is where the brake press back gauge material support arms come into play.    As the material is pushed into the brake press, it has a tendency to fall down before it hits the stops, but if the support arms are mounted on the back rail and adjusted properly, they will hold the material level with the stops therefore resulting in an accurate size bend.
Patent CA-2212444-A1 (CA)
Title: Polarized fiber laser source
Inventor: D AMATO FRANCIS X
IPC: H01S3/07
Filed: 1996-02-27
Abstract: A polarized fiber laser source includes a fiber laser (10) comprising a pair of Bragg gratings (14, 16) at opposite ends of a fiber laser cavity (18) which is doped with a rare-earth dopant so as to allow lasing to occur at a lasing wavelength .lambda.L. A grating tap (26) is provided along a portion of the laser cavity (18) to couple-out a predetermined amount of light along one polarization, e.g., the "s" polarization, at the lasing wavelength .lambda.L. This causes one polarization mode to experience more loss than the other, thereby allowing the fiber laser to lase only on the less lossy polarization mode and causing the laser output light (40) to be polarized only along such polarization.

Abstract: An apparatus and method for die cutting a pre-formed foam container from a sheet of plastic foam materials are disclosed in which the sheet is positioned and clamped between a movable platen and a stationary platen. The movable platen carries a die blade which cuts the container from the sheet, said cut being initiated at the upper surface of the container rim and finishing at the undersurface of the rim to provide the upper surface edge of the rim as a relatively smooth rounded edge. Whatever burrs are created by the cut are found on the undersurface edge of the rim. Upon completion of the cutting procedure, an ejector plate supported on the movable platen is moved to a protracted position to strip the cut container away from the die blade and displace the cut container into a chute of the stationary platen for passage therethrough.
