A venting arrangement for an automotive vehicle is provided in which its rear closure is automatically raised to a slightly open position in response to opening a door of the vehicle so that upon closing the door, entrapped air in the vehicle can escape through the rear to reduce door closing effort. The arrangement includes a latch and pull down mechanism for the rear closure of the vehicle to move the same between a partially open and a closed position and a control means including door jamb s...

A wood chip sorter comprises a shell (22) which at least partially defines a substantially cylindrical sorting chamber (26) into which wood chips are introduced. The shell (22) has a plurality of rotatable shafts (28) mounted thereon with the axes (72) of the shafts (28) being circularly arranged about a central axis (24) of the shell (22). Each shaft (28) has a plurality of discs (80) mounted at spaced intervals thereon with discs of adjacent shafts (28) intermeshing radially to form essentiall...

A cop selecting and conveying apparatus for an automatic winder in which winding units are divided into a plurality of winding sections and different kinds of cops carried on carrying mediums are transferred on the conveying passage to each of the winding sections. A indicia is formed in either the carrying medium or the guide member at the side of the conveying passage and a device for discriminating or detecting the discrimination indicia is disposed at a position to corresponding to the indic...

The offset mechanical gripper is for mounting on a robot for grasping an electrical component. Two pairs of fingers are offset on L-shaped arms. The fingers in a pickup pair move toward and away from a fixed pickup plane to always hold grasped components centered on the plane. The first pair of arms is mounted on a first carriage and the second pair of arms is mounted on a second carriage so that spacing between the carriages controls spacing between the pairs of fingers. The pairs of fingers ar...

In a cyclone classifier wherein the material to be processed is swirled in a tubular casing having a conical lower portion and classified, a cylindrical body is provided in the casing, so as to surround the lower end of a fluid outlet pipe and extends downwardly below an inlet port for the material to be processed, so that the sectional area of passage for the material to be processed swirled in the casing will be made smaller, thus increasing the classifying point while keeping the pressure los...

A railroad crossing is provided in which transverse and end panels are joined by means of splines fitted into indentations on side surfaces of said panels whereby pairs of panels are joined together with a spline fitting partly into each side or end of adjoining panels; and lateral anchor members for fixing the panels adjacent to said rails, the end panels and the outer field panels whereby the need is obviated for affixing the panels to the ties by means of surface spikes. In one embodiment an ...

A wide-body shipping container is adapted for engagement with standard width container supports mounted on various types of carriers by providing a plurality of adapters movably mounted with respect to supporting points on the bottom of the wide-body containers. Each adapter is movable to a position below the container supporting point and engageable therewith in such a manner as to define a new supporting structure spaced laterally inward from the outer most surface of the wide body shipping co...

A system for use with a rail for carrying a moving conveyance, the rail having a web portion, a base portion and an increased width top portion, the system serving to heat the rail top portion to decrease the accumulation of snow and ice thereon, including studs secured to the rail web portion, such as by spot welding, at spaced intervals along the length of the rail, a series of elongated carrier members each defined in cross-section normal the length thereof by an upper trough forming portion ...

A debris catcher comprising a conical screen (filter) in a drill string which defines an annular accumulation space between the screen and the inner wall of the drill string is presented. The central portion of the screen is open to establish an unimpeded flow path. A centrifugal deflector, impeller or similar device above (upstream from) the screen establishes a helical flow pattern in the drilling mud whereby debris entrained in the mud is forced outwardly by centrifugal action. The debris is ...

An apparatus for transferring headed pins includes a frame having a pair of spaced, parallel side rails and an end plate secured between the side rails at one end thereof. A pair of plates are secured together and connected between the side rails at the other ends thereof. The pair of plates have at least a portion of their opposed surfaces spaced from each other, and have aligned holes therethrough for receiving the pins to be transferred. A third plate having openings therethrough is slidable ...
