Title: Supplemental waste recycling container for mounting to a wastebasket
Inventor: BREEN JOHN D
IPC: B65D81/32
Filed: 1992-01-22
Abstract: SUPPLEMENTAL WASTE RECYCLING CONTAINER      FOR MOUNTING TO A WASTEBASKET     ABSTRACT OF THE DISCLOSURE   A supplemental waste recycling container for mounting to either the inside or outside of a larger waste container is provided.  The supplemental container includes an out-turned rim extending around the circumference of its upper edge.  The container also includes two parallel horizontally-extending mounting members extending outwardly from the upper edge of the supplemental container.  The out-turned rim is profiled to mount to either the inside or outside of the larger waste container.  The horizontally-extending mounting members include depending lateral flanges for mounting along sides of the larger waste container when the supplemental container is either mounted to the inside or the outside of the larger container.  The horizontally-extending mounting members, together in combination with the profile of the out-turned rim, thus allow the supplemental container to be easily and securely mounted either to the inside or outside of a larger waste container, without requiring hooks, clasps, or other mounting devices.  The supplemental container is thus ideally suited for use by a consumer in the recycling of refuse.
Patent CA-2061524-A1 (CA)
Inventor: SARI HIKMET
IPC: H04L7/033
Filed: 1992-02-19
Abstract: The phase/frequency comparator comprises a known phase comparator for comparing the phases of an digital input signal with a clock signal of which the period varies to within one time interval with respect to the period of the input signal.      Such a phase comparator produces a first error signal whose sign, and preferably magnitude, vary as a function of the difference between the phases. The phase/frequency comparator is intended to produce a second error signal which replaces the first error signal and whose sign, and preferably magnitude, vary as a function of the difference between the periods.      According to a preferred embodiment, a phase shift assessing circuit detects a predetermined phase shift, e.g. substantially equal to 0, between the clock signal and the input signal during a clock period. A sign detecting circuit detects the sign of the difference between the periods for the predetermined phase shift, and a logic circuit derives two signals having pulse widths as a function of said periods thereby deriving the second error signal by differentiation.      The phase/frequency comparator is particularly intended for a phase locked loop for recovering the timing of the input signal.

Abstract: ABSTRACT METHOD FOR CALIBRATING A WALL THICKNESS INSPECTION MACHINE           A computer senses a voltage which is representative of wall thickness and defines with the use of a voltage/thickness curve the thickness of that wall portion.  To define this curve, a plurality of voltage/thickness points are inputted into the computer.  Each point is defined by sensing and defining the voltage of a wall portion on a calibration standard having a known thickness and defining a calibration thickness corresponding to that voltage using the following equation:           {((Calibration Standard Diameter in inches - Container Diameter in inches) X 0.2) + 1} X Calibration Standard Thickness in mils, and equating these calibration thicknesses to the corresponding voltages produced by the sensing means when sensing said at least two thicknesses of the standard.

Abstract: A ball mill for use in mechanical alloying and grinding comprising a plurality of ferromagnetic balls (22) within a spherical or generally cylindrical chamber or cell (20) of a paramagnetic material. The cell has a substantially horizontal axis of rotation (21). At least one magnet (24) is mounted outside the chamber to produce a magnetic field within the chamber. The or each magnet is moveable between a plurality of locations on an arc (25) centred on the axis of rotation of the chamber.

The surfactant should be added in a quantity sufficient to produce a monomolecular layer over the surface of the particles comprising the powder charge, and with an organic solvent, such as hexane. Metallic amorphous materials can be produced using the ball mill of the invention by (a) obtaining amorphous ribbons from a master alloy of the required chemical composition, (b) crystallising the ribbons by annealing at a temperature of about 600 ·C, then (c) milling the crystallised ribbons in a slight overpressure of dry helium to produce a fully amorphous material.

Title: Method of producing long steel products

Abstract: A method of producing long products of steel by continuous casting in a continuous casting mold, wherein the steel products have the dimensions for the initial pass of a longitudinal rolling mill. Liquid steel is poured into a rotor-cooled continuous casting mold in which the steel solidifies partially with the formation of a ring-shaped strand shell having a round or oval shape in the cross-sectional area of the strand or a polygonal shape having more than four corners, and having a minimum circumference of 200 millimeters. The strand produced in this manner is reduced underneath the mold in its cross-sectional surface area until the strand fully solidifies by means of support members which act in a deforming manner on the strand, such that, while essentially maintaining its circumferential length, the strand is deformed into a shape meeting the requirements with a polygonal cross-section with at least four corners or an oval or round cross-section.
