Abstract: A pneumatic valve which is suitable for use in controlling the operation of a pneumatic drive system such as that used for raising and lowering the body of a dump truck. The valve is opened and closed by a slide member which is mounted in a cylinder fomed in the valve housing. An air inlet passage opens into the cylinder and an air outlet passage and a vent passage open from said cylinder. A first flow control valve in the inlet passage which is operable to close to prevent and open to permit the passage of air from the inlet passage to the cylinder. A second flow control valve in the vent passage which is operable to close to prevent and open to permit the passage of air from said cylinder to the vent passage thereby to vent the outlet passage.

Abstract: The invention is a coated abrasive grinding disk for mounting in the chuck of a drill or the like wherein the grinding pad is of a thermoplastic material having a layer of abrasive material bonded thereto with a layer of thermosetting plastics material.

Abstract: An hydraulic wobble pump having an inlet passage extending inwardly from one end thereof through the central portion of said housing and opening into said wobble chamber. The inlet passage being arranged to admit hydraulic fluid to said wobble chamber substantially centrally between said cylinders so as to be substantially uniformly distributed to each cylinder in use.

Abstract: A method of making a leaded came type window wherein the basic window pane is continuous, the ornamental lites are laminated to the basic pane, the ornamental lites are of substantial thickness, and the came is a channel member with its edges conformed to the marginal areas of the lamination. The came is conformed by placing it over a spline on a table, the spline having the depth of the channel and the configuration of the ornamentation; and the table having the surface of the window and then pressing the edges of the came to conform them to the table. After removal from the table it is applied to the laminated ornamental pane.

Abstract: A privacy screen module is disclosed that is free standing and may be joined with similar modules to make up a screened area. The screen module comprises a self-supporting stand having a hexagonal shape with parallel sides and a pair of end faces at each end, the pair of end faces having an included angle not greater than about 90.degree., frame having a nontransparent screen surface, the frame having upright members extending from the included angle of the stand, the upright members positioned such that a second screen module can be placed at an angle of up to about 90.degree. on either side from an in-line position adjacent the first screen module, and the upright members of the first and second screen modules retain the same minimum distance apart.

Abstract: A multi-port valve comprises a valve seat skeleton and a valve body of readily castible material cast about the skeleton. The valve seat skeleton comprises a plurality of wear-resistant members each having a wear-resistant operative surface formed thereon. The wear-resistant members are secured to one another to retain the wear-resistant operative surfaces thereof in a predetermined fixed arrangement. The valve body has a plurality of valve passages formed therein, one for each valve port, at least one of said passages opening to expose each wear-resistant operative surface for engagement by a movable valve component mounted in each valve passage to bear against and move relative to each wear-resistant operative surface in use. The valve is manufactured securing a plurality of wear-resistant members to one another to form a valve seat skeleton on which the wear-resistant operative surfaces are arranged in a predetermined fixed relationship, and casting the valve body about said skeleton.

Abstract: A packaging machine has a loading station in which load items are loaded into a container. A load transport conveyor extends through the loading station. A load supporting compartment is formed on the conveyor. The compartment has a discharge passage opening from the trailing end thereof and a guide at the trailing end for guiding a load item toward the discharge passage. A receiver is located in said loading station for receiving a load item discharged from the load supporting compartment. A stop is located in the loading station and extends into the path upstream of said receiver whereby the movement of a load item carried by the load supporting compartment along the path is arrested by contact with said stop means and continued movement of the load transporting conveyor causes the load item to engage the guide to be directed thereby through the discharge passage into the receiver.
