Abstract: A clamping member is urged to move in a first direction along a path substantially parallel to a work supporting surface in response to the application of a single linear force, such as a fluid actuated motor. Stop means limit the travel of the clamping member in the first direction. In response to continued force applied by the fluid motor, the clamping member is caused to move in a second direction anchoring a workpiece to the work supporting surface.

Abstract: The area of the cross-section of a piston is reduced while maintaining the over-all dimensions of the cross-section such that the ring is usable in the conventional ring groove of a piston and cylinder assembly. The reduction in the area of the cross-section decreases the inertia of the ring for increased responsiveness to the operating conditions of the assembly. In accordance with a preferred embodiment, the area is reduced by forming a continuous groove in one of the surfaces of the ring.

Abstract: The upper end of an elongate electrical resistance cutting element, extending upwardly from a workpiece supporting table, is movably positionable along an arcuate position of a support member to adjustably vary the cutting angle. A fence for guiding the workpiece during straight line cutting is detachably securable to the table. Alternately, the workpiece may be engaged by a circle guide for establishing a center of rotation for the cutting of cylindrical shapes. An auxiliary cutting unit, especially adapted for free hand cutting and sculpturing, is connectable to the integral electrical energy supply means.

Abstract: A pump supplies pressurized lubricant to an internal combustion engine from an external reservoir through a closed loop system. Delivery channels extending through the crankshaft, connecting rod and other components, supply the pressurized lubricant to the several areas of relative movement. Return channels, extending through the components, conduct lubricant from the several areas to the reservoir. Fuel-air mixture from a carburetor enters the crankcase through the open end of the crankshaft and moves through ports within the several cylinders to the respective combustion chambers. Selected ports are sequentially closed by a valve plate carried by the crankshaft. Incomplete products of combustion are exhausted into an auxiliary exhaust outlet for recycling with the fuel-air mixture. Retainer members engaging the spark plugs assist in dissipating heat therefrom.

Abstract: After the piston, in a piston/cylinder type fluid pressure motor, has moved past the fluid discharge port during termination of the stroke, fluid is forced to flow through a circuitous conduit formed into the outer surface of the piston. The rate of deceleration of the piston is proportional to the length, cross-sectional area, and surface finish of the channel forming the conduit.

Abstract: An evaporative cooler body comprises a non-corrosive, insulative assembly of self-locating, self-jigging parts. Stand-off means are provided for increasing the effective area of the evaporative cooling pads and for improving air flow across the surface of and through said pads. An improved water distribution means permits sheeting of the water across the top surfaces of the evaporative cooling pads to obtain a more uniform distribution of water within said pads. Means are provided for interrupting water flow on the surface of the evaporative cooling pads and returning such water to the interior of said pad so as to increases the overall efficiency of the evaporative cooler. The evaporative cooler cabinet is comprised of a minimal number of reaction injection molded elements of high modulus urethane elastomer. The material insulates both sound and heat providing a quieter running and more cooling-efficient device. Color may be permanently molded into the cabinet.

Abstract: A press, carried by a first table and having punch and die components, receives a rectangular filler sheet and forms a lateral accordian fold sheet. The accordian fold sheet is lifted from the press by transfer means and placed upon an envelope sheet overlaying a second table. Hinged panels carried by the second table fold the envelope sheet over the accordian fold sheet, forming a rigid compartmentalized panel having an opening along a longitudinal edge. The second table, with the opening upright, moves to a position under a receptacle from which granular loose fill material is entered into the compartments through the opening. Subsequently, flaps extending along the panels move to further fold the envelope sheet and close the opening.

Abstract: A pair of half sections forming a hollow chamber with one of the half sections being integrally connected with a rotatable shaft. The shaft includes a passageway through which liquid is inputted to the hollow chamber. One of the half sections is adjustably disposed within the other section thereby forming a variable length valve collar therebetween. A plurality of apertures are formed about the valve collar wherein the effective size of each aperture is varied as the two sections are selectively adjusted with respect to each other to thereby meter the amount of outflow of liquid from the chamber.

Abstract: A golf club includes a club head having two body members and a hosel. Each of the two body members has a planar striking face, and the two faces determine an angle of 90.degree.. Each of the two body members also has a bath surface which is grooved to reduce weight. The hosel joins the body members near the vertex of the 90.degree. angle. A club shaft is inserted into the hosel. Indicia are formed on the upper surfaces of each of the body members which are parallel to a bisector of the 90.degree. degree cycle to aid in aligning the club with the golf ball and the cup into which the ball is to be putted. Tuned resonators are mounted on each of the body members opposite the point on each striking face where the striking faces are tangent to a golf ball touching both faces. The resonators produce audible sounds, which are a function of how the club head strikes a golf ball.

Abstract: A shroud, including a shield placed on either side of an evaporation pad, increases the length of travel air transit time within the pad. Pressurized water, emitted in jets from a plurality of orifices spaced along a manifold, is directed against a diffuser for dissipation and dissemination to the upper edge of the pad. The pad is wetted intermittently as the result of a timer controlling distribution of the water. An auxiliary reservoir, in combination with relocatable pump, inlet valve and pad frames, provide for alternate downdraft as side draft operation. An elongate, arcuate baffle downstream of the evaporative pad alters the direction of the air stream to flow in a substantially opposite direction.
