Abstract: A miter saw design with a cutting arm pivot mechanism that allows the pivot point of the cutting arc to move in a predetermined path in the plane described by the rotating cutting surface. The “floating pivot” enables the tool to accommodate larger pieces of material than conventional miter saws with the same diameter cutting blade. This design also allows the saw to be more compact, lighter in weight, and less complex in comparison to the sliding miter saw. Thus, a miter saw can be provided that provides the cutting capacity of a larger saw with less weight, bulk, and cost than the current alternatives.

Abstract: An electrical energy meter comprises an electrically insulating housing (10) for securing relative to least two mains cables (22,24) each having a conductive core surrounded by a sheath of insulating material. The housing includes respective electrical contacts for piercing the insulating sheath of each cable, a current probe for measuring current flowing in at least one of the cables, and circuit means for calculating and displaying electrical energy as a function of the voltage across the contacts and the output of the current probe. An improved current probe is employed comprising a series of Rogowski coils equally spaced around the circumference of a circle, with the gap between two adjacent coils permitting the current-carrying conductor to be introduced into the loop. An alternative current probe employs two such concentric loops of coils, enabling compensation for the effects of external current source pickup.

Abstract: Rectangular floor panels, a fastening system for joining the panels, and a method for laying and interlocking the panels are disclosed. The panels are provided complementary, form-fitting retaining profiles extending over the length of the sides. The complementary edges of the panels allow two adjacent panels to be positively joined such that displacement of the panels away from one another is prevented, while enabling articulation of the panels with respect to one another at the joint location. The method of installation provides for installing a new panel to a first row and a panel in a second row by first joining the new panel to the panel of the second row at its short side, followed by pivoting the new panel upwards out of the plane of the laid panels along its long side, along with at least the adjacent end of the first panel in the second row, into an inclined position, and sliding the new panel into the retaining profile of the panels in the first row.

Abstract: An engine having a piston-cam assembly powertrain consisting of a rocking yoke assembly that oscillates about its middle point to rotate a multiple-lobe cam. The mechanism is so constructed that cam followers at both ends of the oscillating yoke make contact with the surface of the multiple-lobe cam. When the rocking yoke is oscillated it causes rotation of the camshaft. Alternatively, the rotating cam can cause oscillation of the rocking yoke. The multiple-lobe cam is formed of two identical facing plates having sufficient width to provide an annular groove on the interior face of each plate. Such cam plates are spaced a sufficient width to accommodate the rocking yoke assembly between such cam plates with a pivoting bearing riding within such annular groove. Two connecting rods link the ends of the rocking yoke to two pistons within two parallel cylinders to form a piston-cam assembly powertrain.

Abstract: An apparatus and method for guiding a sail while it is being hoisted on a sail-powered marine vessel are disclosed. The apparatus is a pre-feeder or feeder for use on a forestay, mast, or foremast; the apparatus having two oppositely-facing members that are movable in relationship to each other thereby forming an adjustable opening for receiving and partially encircling the luff portion of a sail. The two members are movable about a hinge and a locking mechanism prevents the members from separating inadvertently. For use with a forestay, the pre-feeder is attached near the bow of the boat or directly to the forestay below the grooved track. The method of using the pre-feeder includes gripping the two members and pulling them apart, inserting the luff, closing the two members, and pulling on a halyard attached to the sail. The apparatus and method of the present invention can reduce the time required to hoist a sail and may be performed by a single crewmember.

Abstract: Disclosed is a fluid dispensing system for precisely controlling the mixing of a first fluid (i.e., a diluent such as water) with a second fluid (i.e., a concentrate) at a mixing point within the fluid dispensing system. A valve is positioned in the dispensing system along the line of supply of the second fluid upstream of the mixing point, such valve being simultaneously actuated through application of positive and/or negative pressure to allow the second fluid to flow through the valve. The application of positive and/or negative pressure is generated from the first fluid to be dispensed by the system and mixed with the second, such that the termination of flow of the first fluid immediately terminates flow of the second fluid to ensure proper mixing of the two fluids in the final solution, thus preventing inadvertent leakage of the second fluid or collection of the second fluid within the flow system which may become subject to spoilage or contamination.
