Patent CA-2203009-A1 (CA)
Title: Odor inhibiting pet litter
Inventor: REDDY MALIREDDY S
IPC: A01N63/00
Filed: 1995-10-17
Abstract: The addition of urease negative bacteria to sodium smectite clay minerals in pet litter inhibits growth of urease positive bacteria for a period of several days, thereby retarding formation of ammonia and other obnoxious odors. Approximately fifty percent sodium bentonite in the litter causes the litter to clump upon wetting, maintaining the urea in contact with the treated clay and also serving as a buffer to favor growth of the urease negative bacteria.

Title: Printing press having cantilevered self-driven cylinders
Inventor: NIEMIRO THADDEUS A
IPC: B41F13/14
Filed: 1998-03-04
Abstract: In order to facilitate removal and replacement of blanket and impression sleeves in a rotary offset printing press, the blanket and plate cylinders are supported in cantilever fashion. The cantilevered cylinders allow axial removal and replacement of the blanket and impression sleeves without temporary support of the cylinder and without removal of any bearings. Each cylinder is rotatably supported on a cantilevered support shaft having a bore therethrough. A drive shaft operatively connected to a drive motor extends through the support shaft bore and engages the inner surface of the generally hollow cylinder. A blanket or impression sleeve mounted on the cylinder is removable using compressed air, which is routed through a bore in the drive shaft and through a plurality of radially oriented passage in a flange on the end of the drive shaft. Each radial passage communicates air to an exit port on the surface of the cylinder, which introduces enough air between the cylinder and the sleeve to permit the sleeve to slide freely for axial removal and replacement.

Patent CA-2238714-A1 (CA)
Title: Improvements to sanding disks
Inventor: VAN OSENBRUGGEN ANTHONY ALFRED
IPC: B24B23/00
Filed: 1996-12-02
Abstract: Accessories for an angle grinder include a disposable rotary sanding disk having quite large shaped ventilating/viewing apertures, for use with a resilient backing plate also having shaped ventilating apertures. The apertures of one or both parts are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use. This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate.      The holes also give the sanding disk more resilience so that a greater area comes in contact with the work and the disk wears more evenly over its abrasive surface.
