Patent CA-2292255-A1 (CA)
Inventor: GRANT JOHN H
IPC: G06K15/16
Filed: 1999-12-15
Abstract: A printing configuration utility provides a single test sheet. The single test sheet is printed twice. The first printing has a first location mark capable of indicating orientation of the first project. The second printing has a second location mark capable of indicating orientation of the second project. After performing the first printing on the test sheet, the printing utility provides the user with instructions for reinserting the test sheet for the second printing. The printing utility asks questions to the user about the first and second printings including the relation between the first and second location marks. Based on the answers given by the user, the printing utility determines the orientation of pages when they are reinserted for the printing the second sides of the pages, and the order of processing of the second side printing.

Patent CA-2304215-A1 (CA)
Title: Flat bottomed plastic bag
Inventor: DEMATTEIS ROBERT B
IPC: B65D30/20
Filed: 1999-06-01
Abstract: An expandable plastic film gusseted bag in which each front panel gusset (64, 66) is connected to a rear panel gusset and each of the panel gussets is foldable between the front panel (63) and the rear panel to provide a continuous bag periphery. A  bottom joins the bottom of the front panel, rear panel, two rear panel gussets and two front panel gussets at substantial right angles to the side edges of the front panel, rear panel, and gussets to close the bottom of the bag and leave only the top (62) open. The improvement provides the plastic bag with eight first linear folding axes adjacent the bottom. A linear folding axis is located within the front panel, each front panel gusset, the rear panel, and each rear panel gussets. Each folding axis extends from the joinder of a gusset at the bottom to a side edge of the front panel or the rear panel and the front panel gusset or the rear panel gusset at an approximate 45° angle. The folding axes are made by a process restricted to a group consisting of a cold seal and a hinge in the plastic film while the film is planar. On opening of the expandable gusseted bag, the bottom seal of the bag disposed adjacent the gussets forms a generally triangular shaped overlay relative to the gussets to form a flat bottom bag.

Title: Slow rotating tool with gear reducer
Inventor: TUCKER JAMES C
IPC: E21B4/00
Filed: 2000-08-02
Abstract: A slow rotating apparatus for use in performing downhole operations. The apparatus generally consists of a motor section with a rotor rotatable in response to fluid flow, a speed reducer section connected to the motor section such that an output speed of the speed reducer section is less than an output speed of the rotor, and a jetting section or other head attached to the speed reducer section and rotated thereby at the speed reducer output speed. A flow passage is defined through the speed reducer section so that fluid may communicate therefrom into the jetting head. The speed reducer section includes an input shaft attached to the rotor. The input shaft has an eccentric portion and has an input gear disposed about the eccentric portion. The input gear is a solid gear having a first outer geared surface and a second outer geared surface. The pitch diameter of the first outer geared surface is less than the pitch diameter of the second outer geared surface. A speed reducer body has a geared inner surface defined thereon in geared engagement with the first outer geared surface. A follower gear is disposed in the body and is in geared engagement with the second outer geared surface. Rotation of the input shaft causes the eccentric portion thereof to rotate in the input gear causing eccentric rotation of the input gear. Eccentric rotation of the input gear is translated into pure rotation by the follower gear which rotates the output shaft.

Patent CA-2317961-A1 (CA)
Inventor: MACMILLAN DONALD JAMES
IPC: F41C33/06
Filed: 2000-09-01
Abstract: Laws require hunters to unload and encase their when entering or retreating from a hunting area one half hour before sunrise and one half hour after sunset. If a firearm is not encased during these times, the hunter is breaking the law.   The invention described and claimed herein relates to an article classed as a gun case for rifles and shotguns. Gun cases are well know and in common use and comprise a rigid or flexible covering that encloses the entire barrel and stock of a gun.     The invention outlined in this application relates to a gun case for rifles and/or shotguns. The invention has two unique, strategically placed openings incorporated into it allowing the gun's own sling to be quickly reattached once the firearm is in the case. The invention is also lightweight and easily storable.        It is common that gun cases either have no carrying mechanism attached to them or that there is a carrying mechanism attached directly to the case. Many gun cases are too heavy and bulky to be stored on one's person in the field and typically those that are lightweight do not have carrying mechanisms incorporated into them. Due to either the dimensions of other cases or the lack of carrying mechanism presently available gun cases are awkward to use in the hunting field and are therefore left behind by hunters or carried around with some inconvenience.
