Patent CA-2041542-A1 (CA)
Title: Labelling machine for closure equipped containers, such as bottles
Inventor: ZODROW RUDOLF
IPC: B65C9/22
Filed: 1991-04-30
Abstract: This invention relates to a labelling machine, and more particularly to a labelling machine for applying labels to containers in such a manner that the labels constitute visible proof that the containers have not been opened.  One such type of container is a beverage bottle having a screw-top closure. Before adhesive and the label is applied to the container, a sensor device located along the transport path of the container determines whether the container to be labelled has a correct closure and also determines whether there is a label correctly positioned to be transferred to the container.  If a beverage bottle with a closure is not detected by the sensor device, adhesive will not be applied to the container.

Abstract: Apparatus for measuring amount of positional deviation of a recording sheet, in which the equation for obtaining the sum of square of the differences between the border coordinate data of the patterns obtained from the video image and the approximate straight line approximating the borders of the patterns is solved with respect to the constants of the approximate straight line, so that a straight line is obtained which represents the borders best, and the positions of the patterns are each determined with at least two approximate straight lines. And a cubic curve is set up which passes through the positions of at least two patterns, and the equation representing the sum of squares of the differences between the cubic curve and the positions of the two patterns with the edge of the recording sheet as a reference position is solved with respect to the variables of the approximate straight line, to obtain a cubic curve equation. The cubic curve equation is utilized to detect the amount of positional deviation of the recording sheet in the direction of conveyance.

Title: Wall panelling
IPC: E04B2/82
Filed: 1991-08-21
Abstract: ABSTRACT OF DISCLOSURE           Conventional prefinished gypsum board panels, i.e panels with a decorative cover usually have irregular edges resulting in irregular, unsightly joints between adjacent panels.  A simple solution to the problem includes a wall panel defined by a sheet of gypsum board with resilient edges for abutting similar resilient edges of adjacent panels, and a cover for laminate on an exterior surface of the sheet of gypsum board for retaining the resilient edges on the sheet.          When such panels are used to form a wall, the resilient edges can be pushed together to form a relatively tight, uninter-rupted joint between the panels.  Typically, the resilient edge is formed of cellular polyethylene.

Title: Filter aid and method for using same for reclaiming oil coolants used for metal working
Inventor: SCHNEIDER JOHN R
IPC: C10M175/00
Filed: 1992-07-02
Abstract: A filter aid material and a method for using same in a filtration system for reclaiming and maintaining coolant oil used in aluminum rolling or working processes are disclosed. The filter aid is a fibrous material which is permeated with an acid material and may be provided in either particulate form as a body feed or as a compressed filter pad. As contaminated oil flows through the filter aid, the acid acts chemically to remove aluminum fines and oxides as well as the aluminum portion of contaminating soap in the coolant oil. Use of the filter aid with acid greatly reduces the amount of conventional filter aid previously used and produces a relatively small amount of residual filter aid which can be disposed of by incineration.

Abstract: An improved method and apparatus for powering and controlling the operation of large diesel-electric off-road haulers of the type in which hauler drive wheels are propelled and retarded by DC electric wheel motors powered from on-board generators, optionally supplemented by DC power, from external trolley lines. In the disclosed system, thyristor-type converters connected into the system AC power grid are used to receive supplemental external power from DC trolley lines and supply it into the AC power distribution grid in the propel mode. The use of such thyristor-type converters makes possible the use of supplemental trolley line power without provision of separate switching or control gear to operate the DC wheel motors when trolley line power is received. Thyristor-type converters also may be used to supply current generated by wheel motors in the retarding mode to retarding resistors, making possible the use of the initial electrical power generated by the wheel motors to replace load requirements of the diesel engine, resulting in substantial fuel savings.

Title: Reagent compositions and their use in the identification and characterization of reticulocytes in whole blood
Inventor: COLELLA GREGORY M
IPC: G01N33/49
Filed: 1992-09-09
Abstract: Methods for characterizing and distinguishing reticulocytes and mature red blood cells use reagent compositions which include organic cationic dyes for staining the reticulocytes in the blood sample and buffer solutions for maintaining a pH of about 6 to about 9. The dyes may be the blue absorption dyes Oxazine 750 or New Methylene Blue. When a zwitterionic surfactant is included in the reagent composition for isovolumetric sphering of the reticulocytes and erythrocytes, and the reagent composition and whole blood sample mixture is passed through the sensing region of a flow cytometer, the light scattered and absorbed by each cell is measured, the erythrocytes can be distinguished from reticulocytes and the volume, hemoglobin concentration and the hemoglobin content of each reticulocyte or erythrocyte, and the mean cell volume, mean corpuscular hemoglobin concentration, and mean cell hemoglobin of the reticulocytes or erythrocytes are calculated from the measured cell-by-cell volume and hemoglobin concentration. One method also includes adjusting the measured absorption signals for pseudo-absorption.
