Abstract: A pressure blowdown system for an oil-injected rotary screw air compressor having an output conduit mounted to a high pressure side of the compressor and having a feedback conduit mounted to an intake side of the compressor, includes a rigid container having a gas reservoir therein, the container having a rigid plate mounted thereon closing the reservoir, a rigid valve housing mounted to the plate, the housing defining a valve spool cavity and having a pressure blowdown vent, the cavity having first and second opposite ends, a valve spool slidably snugly mounted in the cavity for sliding translation between the first and second ends of the cavity, respectively into first and second positions in the cavity. Resilient means are mounted in the cavity for resiliently urging the valve spool from the first end towards the second end of the cavity. A first gas passageway in the plate provides unobstructed fluid communication between the first end of the cavity and the feedback conduit of the compressor.

Abstract: A switch lockout and rocker switch includes a switch cover, a rocker plate, a base, and a lockout slide. The rocker plate has opposite first and second ends, and is pivotally mounted to the cover. The rocker plate is thus pivotable about a pivot axis between oppositely tilted first and second tilted positions. The slide is selectively translatable relative to the base, being slidably mounted on the base for translation of the slide in a slide direction perpendicular to the pivot axis so as to slide relative to the rocker plate between a first lockout position and second lockout position.

Abstract: A stick placer includes a stick magazine and a stick receiver. A stop regulates passage of the lowermost stick from a lower opening in the stick magazine. The stick receiver is rotatable and has a stick receiving pocket. The stick receiver is selectively rotatably mounted adjacent the lower opening in the stick magazine. The stick receiver is rotatable between a stick receiving position and a stick depositing position. In the stick receiving position the pocket cooperates with the lower opening so as to receive the lowermost stick into the pocket when the stop is selectively removed so as to release the lowermost stick from the lower opening in the magazine. In the stick depositing position, the stick receiver is angularly displaced from the stick receiving position so as to dispose the pocket for deposit of the stick from the pocket onto an upper tier of a stack of lumber.

The carabiner mounting members are mounted or mountable spaced longitudinally apart along the each top rail. Each carabiner mounting member extends into the stretcher cavity and defines a carabiner receiving opening which lies in a first plane which is perpendicular both to a vertical second plane containing the corresponding top rail to which the carabiner mounting member is mounted or mountable and to a horizontal third plane which contains the pair of top rails on opposite sides of the stretcher.

The remote actuator is for pushing or pulling the push/pull cable, so as to respectively push or pull the throttle coupler for actuation of the throttle controller when the throttle coupler is mounted to the throttle controller. The remote actuator is mounted to a pull handle. A strap is mountable at one end to the handle and at its opposite end to the ski of the snowmobile so that the ski may be pulled on by a user while the user simultaneously remotely controls the snowmobile throttle.

Abstract: A soil screening device includes a screen frame having a screening surface, and a supporting frame. The supporting frame may have rearwardly disposed rigid uprights supporting the screen frame. The screen frame is pivotally mounted to a first upper member mounted at an upper end of the uprights, for pivoting between a lowered position and an elevated position. The supporting frame has a base frame extending forwardly of the uprights. Upper members of the base frame have at least one wedge selectively positionably mounted thereon, for example atop the upper member of the base frame. The wedge or wedges are positionable to engage a lower edge of the screen frame when in the lowered position bearing down on an upper inclined surface of the wedge or wedges. The wedge or wedges are selectively positionable relative to the upper members of the base frame so as to selectively adjust an angular orientation of the screen frame relative to the uprights.

Abstract: A log processor and log processing method scans a log (L) at a first station (18) so that the longitudinal centerline (32) and a sawing scheme for the log can be automatically determined by a controller (4). The log is oriented at a second station (24) so that the longitudinal centerline is oriented with respect to a vertical plane passing through the feed line. The position of the log is automatically adjusted at third and fourth stations (36, 42) so that the saw blade path (56) through the log is generally parallel to the feed line as the log passes a log exit (12) and through a saw (14). The sawing scheme can include variable tapering sawing from split taper sawing to full taper sawing. Differential steering chain assemblies (37) may be used at the fourth station and may each include continuous loop, log-engaging chains (106) which engage the log above and below the log. Log chipping, profiling heads (62) may be used on either side of the feed line, such as at a fifth station.

Abstract: A mirror housing contains an electrical motor. A drive arm is mounted to the output shaft of a speed reducer mounted on the motor. A linkage arm rotatably couples the drive arm to a rocker disk which is rotatably mounted within the housing. Three hundred sixty degree rotation of the drive arm by operation of the electric motor imparts a back-and-forth arcuate rocking motion to the rocker disk which in turn imparts a linear back-and-forth motion to a wiper mounted over the mirror glass.

Abstract: The fencing system of the present invention includes elongate posts and cross-members. The posts are hollow tubular posts having cylindrical cavities along their length and apertures formed in side walls thereof. The apertures are for accepting in mating engagement therein the cross-members when the cross-members extend between adjacent posts in a parallel array of the posts. The cross-members each have a hole in at least one end thereof although usually in both ends, the holes extending laterally through the end or ends of the cross-members. A rod is inserted or insertable into the cylindrical cavity of at least one of the posts for mating into each hole of each of the cross-members when the cross-members are mated into the apertures. Each hole of each of the cross-members is sized to accept the rod in journalled relation therethrough. Thus, a single rod may releasably lock a plurality of cross-members mounted to a single post.

Abstract: A tree delimber includes a hollow tube having opposite upper and lower ends, the upper end adapted for mounted below an aerial hoist, the lower end having an anti-rotation device mounted thereto for coupling with, mating into and temporarily entangling with the branches of a tree as the trunk of the tree is journalled upwardly through the hollow tube as the tube is lowered onto the tree and down the trunk of the tree. The anti-rotation device inhibits rotation of the tube about a longitudinal axis of symmetry of the tube. A collar is rotatably mounted to the lower end of the tube. An annular saw blade having a lower cutting edge is mounted to the collar so as to dispose the cutting edge downwardly. The cutting edge of the saw rotates in a circle contained in a plane generally perpendicular to the axis of symmetry of the tube. A prime mover is mounted to the tube.

The container is adapted for mounting of service outlets in the cavity in service communication, that is, electrical communication or telecommunication with the service conduits. At least one recess is formed in the sides. Each recess has a side opening exposing the recess horizontally outwardly of the sides. An elongate first threaded member such as a bolt is rotatably and generally vertically mounted within each recess.
