A valve system for use with a cylinder having an extensible rod, includes first and second valve assemblies, each including an inlet/outlet port configured to selectively be coupled with a source of pressurized gas, a check valve biased toward a closed state and having a check valve body at least partially receivable within a first port of the cylinder, a flow control valve positioned in series between the inlet/outlet port and the check valve, and an inlet pilot port connected with the check valve for opening the check valve when supplied with pressurized gas. First and second pilot lines extend to the respective inlet pilot ports from respective outlet pilot ports of the opposite ones of the first and second valve assemblies. When pressurized gas is supplied to the inlet/outlet port of a valve assembly, pressurized gas is also supplied to the opposite inlet pilot port.

A bow stand attachment for an archery bow has a base which mounts to the riser of the bow. The base has a pair of legs extending downward from it. The legs are slid onto stubs which extend away and downward from the outer rim of the base. The ends of the legs and the end of a stabilizer mounted to the bow can cooperate to provide a supporting tripod for the bow. When no stabilizer is attached to the bow, the bow stand and lower pulley act as a tripod to support the bow. Performance of the bow is not affected by presence of the attachment because of its low mass and symmetry on the riser of the bow.

The clamp comprises a fluid actuated piston and cylinder assembly, a frame assembly, first and second clamp arms supported by the frame assembly for pivotal movement about respective first and second pivot axes and axial movement parallel to the longitudinal axis between an unclamped position and a clamped and lifted position, first and second pivot pins respectively defining the first and second pivot axes, first and second slider members respectively supported in first and second tracks for axial movement relative to frame assembly and respectively supporting the first and second pivot pins for axial movement along the first and second tracks relative to the frame assembly, first and second link pins supported proximate the opposite ends of the first and second clamp arms, respectively, the first link pin being movable along the first arcuate track and the first track and the second link pin being moveable along the second arcuate track and the second track, first and second link members connecting the first and second link pins, respectively, to the piston such that movement of piston between the extended position and the retracted position causes movement of the first and second clamp arms between the unclamped position and the clamped and lifted position.

Clamping and lifting mechanism

Apparatus to align the front wheels of a go-cart or other wheeled vehicle on which front wheel toe-in is adjustable. A laser disposed adjacent a horizontally disposed scale is selectively detachably mounted to the rear axle of the go-cart at one of the sides of the go-cart and a mirror member is selectively detachably mounted to the front spindle on the same side of the go-cart. The laser is oriented to emit a laser beam at a perpendicular to the rear axle and onto the mirror of the mirror element which reflects the laser beam back toward the scale. Toe-in of one front wheel of the vehicle may be adjusted precisely by viewing the separation of the emitted laser beam and the impingement of the reflected beam on the scale. The apparatus may then be mounted on the opposite side of the vehicle and the other front wheel adjusted. Alternate mounting means are described which permit the laser and scale and the mirror member to be mounted to the go-cart without removing its wheels and without suspending the vehicle.

A product handling apparatus, components of a product handling apparatus, a method of handling products and a software program for controlling a product handling apparatus. The apparatus includes an induct area, in which products are inducted or fed, either automatically or manually, into the product handling apparatus, an identification area, in which the product configuration, the product type and the product title are identified, a labeling area, in which product labels are printed, applied to each product and verified, and a product sorting area, in which the products are sorted into the individual customer order product collection locations for packaging and shipment to the customer. In the product sorting area, products are diverted by air knife diverter mechanisms, and stackable products are stacked in stacker assemblies. An &ldquo;endless&rdquo; main conveyor assembly conveys products from the induct area, through the product handling apparatus, to the product sorting area. A main controller electronically communicates with and controls, through the software program, the components of the product handling apparatus.

A valve arrangement including a release valve. The valve arrangement controls a piston of a cylinder assembly upon interruption of a source of fluid pressure supplied to the cylinder assembly, the cylinder assembly including a first port and a second port and slideably housing the piston for movement between an extended position and a retracted position. The valve arrangement includes a valve assembly in fluid communication with the source of fluid pressure and with the first port and the second port to control fluid flow between the source of fluid pressure on the first port and between the source of fluid pressure on the second port, and a release valve fluidly connected to the first port and to the second port, the release valve being operable to control flow of fluid from the first port and from the second port. The release valve includes a release valve body including a release valve bore in fluid communication with the first port and with the second port, the release valve body further including a release valve seat, and a release valve member movable between a closed position, in which the release valve member engages the release valve seat to prevent fluid flow through the release valve bore, and an open position, in which fluid flows from at least one of the first port and the second port and through the release valve bore. Preferably, the release valve includes a manually engageable portion operable to allow fluid flow from the first port and the second port.

A clamp for clampingly engaging a portion of a workpiece and for lifting the workpiece from a work surface. The clamp comprises a fluid actuated pistol and cylinder assembly, a frame assembly, first and second clamp arms supported by said frame assembly for pivotal movement about respective first and second pivot axes and axial movement parallel to said longitudinal axis between an unclamped position and a clamped and lifted position, first and second pivot pins respectively defining said first and second pivot axes, first and second slider members respectively supported in first and second tracks for axial movement relative to frame assembly and respectively supporting said first and second pivot pins for axial movement along said first and second tracks relative to said frame assembly, first and second link pins supported proximate the opposite ends of said first and second clamp arms, respectively, said first link pin being movable along said first arcuate track and said first track and said second link pin being movable along said second arcuate track and said second track, first and second link members connecting said first and second link pins, respectively, to the piston such that movement of piston between said extended position and said retracted position causes movement of said first and second clamp arms between the unclamped position and the clamped and lifted position. As the piston is moved from the extended position to an intermediate position, the clamp arms are pivoted to a clamped position. As the piston is moved from the intermediate position to the retracted position, the clamp arms are moved to the clamped and lifted position and the slider members are moved in the tracks, respectively, so that said arcuate portions are substantially misaligned with said arcuate tracks to prevent the clamp arms from moving to an unclamped position.
