Title: Method of regulating drilling conditions applied to a well bit
Inventor: GOLMAN WILLIAM A
IPC: E21B12/02
Filed: 1997-03-21
Abstract: A method of regulating drilling conditions applied to a given well bit comprises assaying the compressive strength of the formation in an interval to be drilled by said bit. Wear of critical bit structure of the same size and design as in said given bit and which structure has drilled material of approximately the same compressive strength as that so assayed, is analyzed along with respective drilling data for the worn structure. From said analysis, a power limit for the respective compressive strength, above which power limit excessive wear is likely to occur is determined. Drilling conditions, such as rotary speed and weight-on-bit, at which the given bit is operated are regulated to maintain a desired operating power less than or equal to the power limit.  Where several feasible rotary speed/weight-on-bit combinations may result in the desired operating power, these conditions are optimized.

Abstract: A portable, retractable ground cover that is positioned into the garden.   The "Portable Greenhouse"is a plastic device which is light in weight with a manually cranked arm which extends a ground cover supported by stakes that have been therein positioned into the ground. This was designed to eliminate the current problem of covering plants whenever there was danger of frost. Methods used to date have been various and needed to be removed usually by the next day. My invention may be erected by one person and may be left in positon for the text day or weekends or longer if needed. The unique cover allows the rain to penatrate and is lightweight so there is no damage to plants when rolling back up for storing. The main bar is designed to contain and extract an 8 ft. long ground cover that is attached by velcro to a holding bar with velcro attachments at the other end The main roller bar holds the cover and handle apparatus. The secondary holding bar is placed at the appropriate distance for the ground cover to be adherred to when extended.      The legs are 2 1/2 ft. in height made entriely of plastic. The legs are plastic pedestal brackets where-in the bars are snapped into place. My invention is completely operable by one person and may be modified by an extension bar to accomodate a much larger garden area with larger groung covers. With this modification plastic wickets would be used to uphold the covering keeping damaging weight from sensitive plants.

Title: Composition and process for treating metal
Inventor: DOLAN SHAWN E
IPC: C23C22/28
Filed: 1997-06-27
Abstract: Heating an aqueous mixture of a fluoroacid such as H2TiF6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can be mixed with soluble hexavalent and/or trivalent chromium, and preferably also nitrate and chloride ions to produce a composition that provides a conversion coating with good protection against corrosion while requiring substantially less chromium than previous coatings of equal corrosion protective quality.

Patent CA-2264469-A1 (CA)
Inventor: THOMAS KEITH WILSON
IPC: B66F15/00
Filed: 1999-03-01
Abstract: During the operation of a snowmobile or other all terrain vehicles, it is common for such vehicles to become mired in snow or mud etc. Extraction of such vehicles without the assistance of another person usually requires that the vehicle be lifted manually from a deep rut and repositioned on more tractionable terrain before it can proceed.  Lifting of such vehicles manually is extremely difficult, often requiring a dead vertical lift of hundreds of pounds while standing on soft or unstable terrain. This apparatus is designed to be transported on the vehicle and can be set up in seconds to assist in freeing it. The apparatus allows the operator to use their own body weight to lift and reposition the vehicle through the use of leverage, while at the same time providing a much larger and more stable lifting platform. Lifts of up to three times the operators body weight can be achieved without the inherent physical dangers of manual lifting.

Patent CA-2273973-A1 (CA)
Inventor: KIZAWA MAKOTO
IPC: H04N19/40
Filed: 1998-10-07
Abstract: A color facsimile comprises a multilevel JPEG coding/decoding means (106) for coding color data, and a binary JBIG coding/decoding means (108). When the receiving side facsimile employs the same recording system as that of the transmitting side facsimile, color data read out by a color correcting section (119) are corrected with a correction value corresponding to the characteristics of a recording means of the transmitter, binarized and coded by the JBIG coding/decoding means (108) and transmitted. When the receiving side facsimile does not employ the same recording system as that of the transmitting side facsimile, the read out color data are coded by the JPEG  coding/decoding means (106) and transmitted. Since the amount of data transmitted can be reduced without causing degradation of the image quality, the communication time can be shortened and low memory capacity can be avoided.

Patent CA-2280327-A1 (CA)
Inventor: DIBIASE JOSEPH J
IPC: D01F6/84
Filed: 1999-08-17
Abstract: The present invention discloses and claims a novel process for the formation of high denier as-spun and heat-treated multilobal filaments of a thermotropic liquid crystalline polymer. Preferred embodiments include process for the formation of as-spun and heat treated octalobal monofilaments of a few wholly aromatic polyesters and polyesteramides. The process involves (a) heating of a thermotropic liquid crystalline polymer to above its melting transition temperature; (b) passing said molten polymer through an extrusion chamber equipped with an extrusion capillary having a multilobal cross-section to form a multilobal filament; and (c) winding the filament at a suitable draw-down. The filaments so formed are of at least 50 denier per filament (dpf) and feature essentially uniform molecular orientation across their cross-section.  In a final optional step, the filaments are heat treated in stages to form filaments exhibiting excellent tensile properties. Both as-spun and heat-treated filaments feature remarkably good tensile properties comparable to those of round filaments.  Most importantly, the multilobal filaments of this invention feature much superior adhesion properties than the conventional round filaments.

Title: Storage and dispensing unit for merchandise bags
Inventor: MILLS DANIEL J
IPC: B65D83/08
Filed: 1999-10-05
Abstract: A pack of merchandise bags is provided in a closed storage and dispensing unit. A portion of the unit is removable to provide a window through which the bag pack is exposed. Each bag in the pack is provided with a front and rear tab at the top, with the rear tab of a bag being attached to the front tab of the next bag. In addition, the rear tabs are formed together in a stack which is secured inside the unit, and each rear tab is attached to its respective bag through a relatively weak perforation. Thus, when a bag is withdrawn from the back pack by means of the front tab, the bag is opened, because the rear tab is retained to the stack of tabs. However, as additional force is exerted on the bag, the rear tab is torn free at the perforation. Since this rear tab is attached to the front tab of the next bag, the next bag is automatically opened.
