Abstract: The invention is a cost-effective method and formulation for cold paving applications that can be used to convert an unpaved surface, such as a gravel or dirt roadway, into a paved surface. The method includes applying an asphalt emulsion comprising asphalt, water, one or more emulsifiers, and a polymer to an existing unpaved surface to provide a layer of asphalt emulsion. An aggregate is then deposited over the emulsion layer to form a paved surface. The asphalt emulsion is formulated so that it can be used in a wide variety of conditions and with locally available aggregate. The set rate and viscosity of the asphalt emulsion can be selected so that it is able to penetrate partially into the unpaved surface to further improve the stability and rain resistance of the roadway.

Abstract: A screw drive with an antibacklash mechanism and method including a pair of nuts rotatably mounted in a housing which are urged to rotate in opposite directions to engage flanks of leadscrew threads with a torsional spring interposed between the two nuts to eliminate backlash. A pivoted control lever has opposite ends engaged with a respective nut so that if either of the nuts rotate slightly, the other nut is also rotated slightly to prevent jamming. Locking cams are also provided to limit the control lever motion when the screw is sufficiently heavily loaded axially sufficiently to overcome the torsional spring by locking the lever to the housing.

Abstract: A container assembly for packaging nonliquid material includes a can body that may be filled with nonliquid material and an end panel that is secured to the can body, preferably by seaming. A score line that is formed in the end panel defines a first removable portion and a second nonremovable portion. Structure such as a tab is provided for initiating separation of the first removable portion from the second nonremovable portion at a first location along the score line that defines an axis of symmetry about which separation of the first removable portion from the second nonremovable portion during opening will progress substantially symmetrically. The score line is shaped so that the second nonremovable portion defines a spoon leveling shelf that is shaped and sized to permit a consumer to level a spoonful of nonliquid material. Moreover, at least one exposed edge of the spoon leveling shelf is afforded cut protection by a safety fold.

Abstract: A method of monitoring/controlling Thysanoptera (hereafter thrips) by the use of a behaviour modifying compound of Formula (1), wherein Formula (1) is:— where R1 is a monoterpenyl group and R2 is a C3-C5 group.

Abstract: Temperature and precipitation are predicted from temperature and precipitation during the same week in one or two previous years and normal temperature and precipitation during that week. The difference between the previous year's value and the normal value is calculated and used to determine which forecasting formula is used. The result can be prepared in graphical form by time, geography, or both for use in planning advertising, retailer stock purchases, or the like.

Abstract: Fruit or other objects placed on the conveyor and spun by the conveyor are properly oriented on the conveyor by the method and apparatus of the invention by ejecting one or more adjacent touching objects or ejecting objects which form stacked triplets. An optical sensor determines when there is or is not a gap between objects and relates that gap detection to the position of the objects on the conveyor. Detection of a continuous signal through a controller circuit causes a downstream solenoid to be energized according to predetermined timing. The solenoid in turn, when energized, rotates a finger which is coupled to, carried with the conveyor system and situated underneath the pocket between adjacent spools. The finger rotates upwardly and ejects the objects sitting in the pocket, thereby removing the misplaced or touching objects on the conveyor belt.

Abstract: Described is an apparatus and method, particularly applicable to a brush bed conveyor system, by which objects, typically citrus fruit, are washed or sprayed. A moveable high pressure spray manifold is contained within a manifold carriage and is disposed within the conveyor chassis such that it is moved along above a brush bed by a conveyor chain. Separation bars extend from the conveyor chain to segregate the objects into queues retained within the spray pattern of the manifold. When the manifold reaches a predetermined end position, a release latch is decoupled from the separation bars to disconnect the separation bars and conveyor chain from the manifold carriage. The predetermined end position is sensed and the manifold carriage is quickly returned to its initial position by means of a selectively activated pneumatic piston assembly.

Abstract: An apparatus peels fruit, in particular citrus fruit, by washing and sterilizing the fruit in a sterilizing bath. The washed and sterilized fruit is delivered to a perforator which makes a plurality of perforations through the outer surface of the peel of the fruit over its entire surface. The perforated fruit is then delivered to a conveyor which loads and orients the fruit so that it is spinning on the stem axis with the equator of the spinning fruit exposed to a plurality of slitting knives. The knives slit an equatorial cut through the outer surface of the peel. The slit and perforated fruit is then delivered to a carousel of canisters. Each canister is filled with fruit and an aqueous solution of a commercial pectinase. The solution is vacuum infused into the fruit so that the albedo attaching the peel to the fruit substantially disintegrates over a predetermined time period.
