    Abstract: A rotary air compressor of oil sealed type includes a stator containing a rotor, oil injectors arranged to inject oil into the interior of the stator, an oil sump connected by a first oil pathway to the oil injectors and an oil cooler situated in the first oil pathway. A thermally responsive valve situated in the first oil pathway is arranged to open only when the temperature of the oil has reached a predetermined value whereby no oil is injected through the oil injectors before the temperature of the oil has reached the said predetermined value.

    Abstract: A packing is provided with a multilayered construction and a cup-like shape. The packing is configured to be carried in a packing holder for reciprocating motion within a pump cylinder. Some of the layers in the packing terminate on the convex face of the cup shape at radially spaced locations therearound. Thus, a peripheral portion of a number of the layers behind the cup lip are exposed to be engaged by the cylinder wall at a continuous contact area therearound. The hardness of the layer located outermost on the convex face is the greatest, and the hardness of each succeeding adjacent layer is lesser than the one immediately preceeding when progressing toward the cup lip along the convex face. Extrusion of the packing between the packing holder and the cylinder wall and subsequent severe localized wear is resisted by the greater hardness layers. A more uniform distribution of pressure across the area of contact between the packing and the cylinder wall is provided by the reduced tendency of the packing to extrude and the decreasing hardness sequence of adjacent layers.

    Abstract: A foldable two-piece boom is provided with an outer boom wing pivoted about an upright axis and being slidable relative to an inner boom arm which is pivoted to a frame member for both horizontal and vertical motion. A spring and cables in a mounting mechanism are arranged to permit the outer wing to pivot either forwardly or rearwardly when contacted by an abutment and thereafter gently returned to a neutral position parallel to the longitudinal axis of the inner boom arm at a controlled rate which minimizes impact forces. The spring and cables are also arranged to permit pivotal movement of the boom in a vertical plane while maintaining the inner and outer sections in vertical planar alignment. In response to the horizontal swinging of the boom through 90.degree. from its extended to its folded transport position, the spring and cables cause the outer wing to fold in the opposite direction of the arm to firmly clamp against the inner arm.

    Abstract: A quintuplex mud pump has a crankshaft supported in the pump by external main bearings. The crankshaft has five eccentric sheaves, two internal main bearing sheaves, and two bull gears. Each of the main bearing sheaves supports the crankshaft by a main bearing. One main bearing sheave is disposed between second and third eccentric sheaves, while the other main bearing sheave is disposed between third and fourth eccentric sheaves. One bull gear is disposed between the first and second eccentric sheaves, while the second bull gear is disposed between fourth and fifth eccentric sheaves. A pinion shaft has pinion gears interfacing with the crankshaft's bull gears. Connecting rods on the eccentric sheaves use roller bearings and transfer rotational movement of the crankshaft to pistons of the pump's fluid assembly.
