Title: Laminate and package made therefrom
Inventor: KOCHER PATRICK N
IPC: B65D81/20
Filed: 1999-05-11
Abstract: A laminate (24) includes: a) a first, substantially gas-impermeable film (29);  b) a second, delaminatable film (28); and c) a third, gas-permeable film (26). The second film (28) is positioned between the first (29) and third (26) films and the laminate (24) is capable of delaminating within the second film (28) when the laminate is subjected to a delaminating force. A portion of the delaminatable film (28) thus remains bonded to the gas-permeable film (26) after delamination.  The laminate (24) is ideally suited as a lidding material for a case-ready package. The third, gas-permeable film (26) is preferably bonded directly to a support member containing therein or thereon a fresh red meat, poultry, or other product (16), while the first, gas-impermeable film (29) forms the outermost surface of the lid (24). The gas-impermeable film (29) and a portion of the delaminatable film (28) can be peelably removed from the package (10) to thereby allow atmospheric oxygen to enter the package.

Inventor: INGRAM VICKI
IPC: A46B15/00
Filed: 2001-02-12
Abstract: A tool (10) for removing ice, snow, and general debris from vehicles. The tool (10) broadly comprises an elongated handle (14) having opposed first and second ends, a brush head (12) pivotally coupled to the first end of the handle (14) by a pivot mechanism (16), and a scraper (18) attached to the second end of the handle (14). The pivot mechanism (16) comprises a spring-loaded knob (46) which may be easily actuated with one hand and whose large proportions make operation by gloved hands convenient. To pivot the brush (12), an operator merely depresses and turns the knob (46) of the pivoting mechanism (16). Two pair of detents (21), arranged 90° to one another, lock the brush (12) into a first position, in which the brush is aligned with the handle (14) and may be used with a sweeping motion, or a second position, in which the brush (12) is perpendicular to the handle (14) and may be used with a pushing or pulling motion.

Title: Torsional shock absorber for a drill string
Inventor: SOLORENKO MICHAEL
IPC: F16D3/68
Filed: 2001-04-10
Abstract: A torsional shock absorber dampens rotary shock loading on a well drill string. An outer housing has drive splines on an inner surface. A  mandrel is located within the outer housing and has drive splines on an outer surface that fit between the drive splines on the inner surface of the housing. Dampening bars are positioned longitudinally between the splines of the outer housing and the splines of the mandrel to absorb shock from non-uniform torsional loading at the drive interface between the outer housing and the mandrel. A balancing piston is located within the tool to compensate for pressure difference between drilling fluid pressure and lubricant contained within the shock absorber. A thrust bearing assembly is provided to accept axial thrust loads from the outer housing and transfers the load to the splined mandrel. A retainer transfers tensile loads from the housing to the mandrel through the thrust bearing.

Title: Drool prevention system
Inventor: KUSHNIR YOSIF
IPC: B29C45/76
Filed: 1990-07-26
Abstract: An injection mold for use with a molding press has four mold levels in axially stacked relation, permitting a substantial doubling of output for a given size of press as compared with a back-to-back two level stacked mold. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the centres of the stacked mold block series. The centrally located distribution block is connected, in use isolation, sealed relation with the injector head, being axially displaceable therefrom in contin uing sealed relation upon the opening of the mold. A drool prevention valve system, located at two of the mold inter faces, to preclude drooling of fluid plastic stock upon open ing of the molds includes pressure fluid actuators for operat ing the valves, wherein the pressure fluid may comprise the fluid plastic stock. The valve system also includes a de pressurizing valve provision, wherein, upon opening of the mold interfaces the stock distribution passages are substan tially depressurized, to thereby reduce any tendency to drool.      The mold includes axial adjustment means to compensate for differential variations in overall mold length within the press, due to changes in effective mold temperature.

Patent CA-2351498-A1 (CA)
Inventor: ALLPORT DAVID
IPC: H04N21/482
Filed: 1999-12-27
Abstract: A method for displaying Electronic Program Guide (EPG) data in substantially a grid format, without using "channel" information as an axis. More specifically, instead of being presented by channel and time, the EPG data is only presented by time. Various truncation algorithms are used to allow program descriptions to be shortened, enabling placement of the descriptions into gaps or empty cells in an available row. This allows the program information from multiple channels to be displayed in a single row thereby improving the efficiency of display space use. In a specific application, the techniques described above are used to display EPG data for multiple categories (140a-140f) in a grid (G9) on the same screen.

Patent CA-2355349-A1 (CA)
Inventor: ROMANTCHIKOV YURI
IPC: C12N15/66
Filed: 1999-12-17
Abstract: The present invention provides vectors and methods which improve the efficiency of nucleic acid insertion into circular vectors, which generally facilitate nucleic acid cloning and specifically facilitate the preparation of DNA libraries. In general, the present invention involves separation of the cloning process into two distinct steps: (a) insertion which is done at a hi gh nucleic acid concentration favoring intermolecular joining, and (b) circularization which is performed at a low nucleic acid concentration favoring intramolecular circularization. The present vectors generally have distinct insertion ends and circularization ends which are blocked from covalent joining during the insertion step. Circularization ends contemplate d by the present invention include complementary cohesive ends and topoisomera se- linked ends. The present vectors and methods allow minute amounts of nucleic  acid inserts to be efficiently cloned. Moreover, little or no insert size selection occurs with the present methods so that large as well assmall nucleic acid inserts are readily inserted into the present vectors. Thus, DN A libraries which are representative of the entire range of size of DNA insert s can be made, and, for example, full length cDNA libraires are readily obtain ed.

Patent CA-2363904-A1 (CA)
Title: Transporting sulfur pellets
Inventor: D AQUIN GERARD E
IPC: C01B17/02
Filed: 2001-11-29
Abstract: A process and apparatus for effecting the transportation of sulfur pellets with the recovery of sulfur fines is disclosed. This is accomplished by a combination of steps and apparatus which include pumping water from a water supply into solid sulfur pellets with a jet-venturi/eductor pumping system to produce a sulfur water slurry containing sulfur pellets and sulfur fines, pumping the sulfur water slurry with one or more rotating disk/boundary layer pumps to a series of static screens to remove large lumps and impurities, a sulfur fines slurry, and a washed sulfur pellet slurry, contacting the sulfur pellet slurry with a dewatering disk, belt or equivalent to remove substantially all the remaining water, transporting the dewatered sulfur pellets to storage, pumping the sulfur fines slurry to a hydrocyclone to separate all the water from the sulfur fines, recycling the recovered water to said water supply following the addition of an alkaline-neutralizing agent when needed, and recovering the sulfur fines. The invention substantially reduces air pollution by reducing the amount of sulfur fines released into the air during the unloading of sulfur pellets in bulk. The hydraulic transportation feature of this invention eliminates the use of mechanical loaders, cranes, open air hoppers, and open air transfer points that normally create and disperse sulfur fines into the atmosphere during their use in the movement of solid sulfur. It enables sulfur pellet transfer operations to take place in most weather conditions, rather than requiring interruption when wind speed and time exceed regulatory guidelines. The State of Florida requires operators to cease the unloading of sulfur pellets from a marine vessel whenever wind speed exceeds 18 miles per hour for a 5-minute time span.
