Abstract: A pneumatic tire is provided herein for heavy duty use. Such pneumatic tire has a profile comprising a tread profile extending between tread edges. A buttress profile extends radially-inwardly from a point on the surface of each tire sidewall. A  connecting profile extends between each tread edge and the point. In a cross section including the tire axis, the tread profile is formed by an arc having an outwardly-swelling curvature of a radius, each buttress profile is formed by an arc having an inwardly-swelling curvature of a radius and each connecting profile is formed by an arc having an outwardly-swelling curvature, and intersecting the tread profile at the tread edge to form an angled corner, and which is smoothly-connected with the buttress profile at the point. The ratio of the radial distance between the tread edge and the equatorial point on the tread profile to the axial distance therebetween is 0.09 to 0.12. The ratio of the axial distance to the axial distance between the equatorial point and an imaginary point at which the tread which has the radius of curvature and the buttress arc which has the radius of curvature intersect each other if extended, is 0.85 to 0.95. The inclination angle of the tangential Line to the connecting profile drawn at each tread edge is 20 to 60 degrees with respect to the radial direction of the tire. This pneumatic tire has improved shoulder wear resistance and wandering performance.

Patent CA-2081861-C (CA)
Inventor: FAILING BRUCE F JR
IPC: G06Q50/28
Filed: 1992-10-30
Granted: 1999-04-06
Abstract: An improved system for space management in retail stores is described.  The space management system includes price display labels mounted on rails along the edges of shelves in a store.  A communications link between the computer and the labels permits the computer to address each label by a logical address and to determine the physical location of each label to within a resolution of typically four feet.  The system prepares price audit lists and adjacency audit lists that permit economical use of the time of store personnel during the audit.  The lists are generated in such a way that the items on a particular list are physically contiguous; thus once the correct general area has been located by the auditor little additional time need be spent locating the individual items.  In performing an audit of product facings, the user is able to use the display hardware, including the pushbutton on each label, as a data collection system for product facing information.  In product location mode, the user starts at the first label at one end of a shelf and presses the button on the first label.  The user moves to the second label, presses its button, moves to the third label, and the process is repeated for each label along the shelf, and for the rest of the shelves in the area being audited.  This permits the system to collect information as to the sequence of labels along a rail.

Patent CA-2100203-C (CA)
Inventor: COLLINS GEORGE E
IPC: A01D46/26
Filed: 1993-07-09
Granted: 1996-09-03
Abstract: The invention relates to a harvester for lowbush berries such as wild blueberries. A truss section is mounted to the three-point hitch of a tractor adapted to run in reverse, the truss section pulling a pair of laterally and longitudinally offset picking heads contained within the periphery of the truss section. The picking heads are floatingly connected to the truss section so that they are free to follow the contours of the ground. Each picking head mounts a rotating, tine-carrying reel therein and is connected to one end of a counterbalance system, the other end of the system being carried by the tractor. The counterbalance system includes counterweights that can be raised or lowered between upper and lower limits at the will of the operator so as to offset the weight of the picking head, so that as little as 25 % thereof is acting on the ground. This means that there will be little damage to the picking head if it encounters obstacles such as rocks or tree stumps during harvesting. The counterbalance system can also be used to raise the entire head clear of the ground to pass over obstacles or to permit travel of the harvester to or from the fields to be harvested.

Title: Combination direct and indirect closed circuit evaporative heat exchanger
Inventor: CARTER THOMAS P
IPC: F28F25/08
Filed: 1994-05-26
Granted: 1998-07-07
Abstract: A heat exchange apparatus is provided with an indirect evaporative heat exchange section and a direct evaporative heat exchange section.  A uniform temperature evaporative liquid is downwardly sprayed into the indirect section to indirectly exchange sensible heat with a hot fluid stream flowing within a series of enclosed circuits which comprise the indirect evaporative heat exchange section.  After the evaporative fluid descends through the entire indirect heat exchange section and absorbs heat, it is distributed across fill media within the direct evaporative heat exchange section for cooling.  Separate streams of ambient cooling air are simultaneously drawn into each of the heat exchange sections to evaporatively cool the evaporative liquid flowing within each section.  The water cooled in the direct heat exchange section is then collected in a sump where it is allowed to mix and resultantly become uniform in temperature before being redistributed.  The initial uniform temperature of the cooling water is operationally the most controlling factor in maximizing the uniformity and performance of the indirect heat exchange section and the tower as a whole.          The indirect heat exchange section is constructed from a series of spaced circuits having a continuous serpentines shape where the internal fluid to be cooled flows upwardly at a uniform rate and temperature from circuit to circuit.  As the water descends, it indirectly exchanges sensible heat with the fluid uniformly from circuit to circuit along the vertical and horizontal heights of the indirect heat exchange section.  An additional gain in the uniformity of circuit to circuit performance and heat exchanged is realized when the cooling air stream passing through the indirect heat exchange section is parallel or concurrent with the cooling water flow.  The apparatus can be used as a fluid cooler, an evaporative condenser, or as a wet-air cooler.
