Title: Method and apparatus for planar drag strip casting
Inventor: POWELL JOHN C
IPC: B22D11/06
Filed: 1990-10-02
Abstract: ABSTRACT OF THE DISCLOSURE The present invention is directed to an improved process and apparatus for strip casting. The combination of a planar flow casting nozzle positioned back from the top dead center position with an attached nozzle extension, provides an increased level of casting control and quality. The nozzle extensionprovides a means of containing the molten pool above the rotating substrate to increase the control of molten metal at the edges of the strip and increase the range of coating thicknesses which may be produced. The level of molten metal in the containment means is regulated to be above the level of melt supplying the casting nozzle which produces a condition of planar drag flow with the casting substrate prior to solidification.
Patent CA-2026936-A1 (CA)
IPC: G01R27/22
Filed: 1990-10-04
Abstract: An electrodeless conductivity measuring cell having three toroids.  In one arrangement, the three toroids are stacked together wherein the center toroid is used for sensing and the two outer toroids are the drive toroids. Alternatively, the center toroid may be used as the drive coil and the outer toroids used as sense coils.  Washer-shaped, grounded discs are placed between the outer toroids and the center toroid to provide for improved noise rejection.  A method of validating the fluid conductivity measurement of such a measuring cell.  The fluid conductivity is measured with a three-cell configuration, and then it is measured with a two-cell configuration.  If the conductivity is observed to be the same, the cells are likely functioning normally.  If fluid leaks into the cell cavity, the measurement of conductivity will change.

Patent CA-2030609-A1 (CA)
IPC: B65D41/04
Filed: 1990-11-22
Abstract: ABSTRACT OF THE DISCLOSURE A polyethylene cap,  for use with containers, particu-larly polypropylene containers for containing medical speci-mens in preservative fluid such as formaldehyde, is provided with a 3-face seal, wherein a rim portion of the container is trapped in  sealing,  contacting  relation on  three mutually adjoining faces, whereby any tendency of the container rim to "relax" out of sealing engagement with a contacting face por-tion of the cap is effectively precluded by the geometry of the cap seal.  In the case of polypropylene, which is suscept-ible to such "relaxation", the subject cap enables the effect-ive sealing of polypropylene containers so that advantage may be taken of the superior properties of polypropylene in non-reactive, secure containment of possibly contaminated medical specimens in liquids such as formaldehyde, a known carcinogen. In a preferred embodiment the cap has a "feel" element,  to give actual indication of engagement.

IPC: B65B67/00
Filed: 1991-06-20
Abstract: Abstract Most boxes for stacking and bundling of newspapers for like materials) normally require either careful lifting of the newspapers while bundling them or placement of string prior to the placement of the first item in the box. If string is placed then guides are sometimes used to keep the string in place. In our invention the newspapers are elevated on a platform and the box is open sided so that string can be placed under the elevated platform and tied around the stack without the need to lift the newspapers.  As well, the open sided box design and elevated platform allows the placement of the string to be done at any time the user requires the stack to be bundled.
