Abstract: The novel controlled-flow lubricating system utilizes a casing that forms, in use, an enclosed oil well. At least one bearing is disposed inside the well. A shaft is journaled in the bearing. A pumping member is pressed onto the shaft adjacent to the bearing for rotation therewith. Upon rotation with the shaft, the pumping member forcefully injects lubricant from one side to the opposite side of the bearing, thereby flushing, cleaning and lubricating the bearing's engaging surfaces. The preferred pumping member is a circular impeller having a plurality of vanes facing an eccentric cavity in an opposite portion of the wall in the well. This eccentric cavity and the impeller intensify the flow of the recirculating lubricant between the well and the reservoir.

Abstract: The bearing lubricating system comprises a casing having a bore which defines a reservoir and a well sized to receive a sufficient volume of a suitable liquid lubricant. A return passage in the casing allows fluid flow from the well to the reservoir. A shaft extends through the reservoir and through the well. At least one bearing is situated in the bore between the reservoir and the well. A pumper element is mounted on the shaft for rotation therewith within the well. A pair of end seals seal off the opposite ends of the bore from the ambient.

Abstract: The exerciser is adapted to simulate the motions and conditions incident to making turns on a ski slope, and for perfecting body movements that are important for the safety of skiers on a snow-covered slope. The exerciser has a platform for supporting a person and a support including a frame for supporting the platform for rotation in accordance with shift of weight and movements of the person. Restraining spring is coupled between the platform and the frame. The spring is effective to yieldably resist with increasing force the increasing tendency of the platform to rotate clockwise or counter-clockwise from a neutral position relative to the frame.

Abstract: The shears have two levers pivoted together, each having a cutting edge at the forward end thereof and an operating handle at the rear end thereof. The lower lever has a hinge hub forming a bearing surface which is laterally offset with respect to its cutting edge and which projects forwardly and upwardly toward its cutting edge.

Abstract: The gate and swing valve has a body which defines at least one valve seat. A closure member inside the valve is pivotably mounted on a support. A cam and cam follower operatively couple the cam to the closure member. A stem has one end coupled to the cam for moving the closure member in a linear motion, in a swinging motion, and then in a linear motion toward the valve seat.

Abstract: A two-to-one or greater slope is stabilized by rolling a vibratory compactor upslope and simultaneously vibrating the compactor's roller. The compactor comprises a frame on which is rotatably mounted a suitable compaction roller. An engine is rotatably mounted on the frame, and means are provided for adjusting the tilt of the engine relative to the frame, so that, in use, the engine will remain upright while driving the vibratory shaft of the roller. The engine is remotely controlled, as by radio waves, by an operator riding a vehicle on the shoulder of the embankment. A crane and winch on the vehicle riding on the embankment control the movements of the compactor on the slope.

Abstract: The long-stroke pumping apparatus has a frame, a drum, and a pair of sheaves mounted on the frame. A traction cable is carried by the drum. A cable connector is connected to one end of the traction cable which is guided over one sheave into an oil well. A counterweight assembly is connected to the other end of the traction cable which is guided over the other sheave into a counterweight well. A reversible power means, preferably a hydraulic motor, rotates the drum a number of turns in one angular direction and then in an opposite direction during one complete stroke of pumping operation. A load cable is also supported and guided by the sheaves, and the cable connector and the counterweight assembly are also suspended from the opposite ends of the load cable. The load cable is not drivingly connected to the drum.

Abstract: The fluid-pressure actuated press is mounted on a column structure. It has a ram, a piston, and an associated piston rod. The free end of the piston rod reciprocates downwardly. A support adjustably mounts the ram on the column structure. A lever bar has a proximate free end in engagement with the free end of the piston rod. The distal end of the lever bar is pivoted about a fixed fulcrum carried by the support. A chuck rod is slidably mounted relative to the support along an axis which is parallel to the axis of the piston rod. The chuck rod is pivotably associated with the lever bar at a point intermediate its ends, whereby the reciprocation force on the piston rod is multiplied by the lever ratio to cause reciprocation of the chuck rod with the multiplied force.

Abstract: A pipe is fabricated from rolls of flat metal plate by continuously moving the plate into a pipe-forming station which shapes the flat plate into a pipe having a longitudinal seam therealong. A plate arc welding machine welds consecutive plates to each other thereby maintaining continuity of plate movement. Equal sections of the longitudinal seam are consecutively welded in a leapfrogging manner using two welding units movably positioned on the opposite sides of the moving pipe. The welding units alternatingly weld alternate and overlapping sections of the longitudinal seam. The welding operations are carried out without interference with the continuous movement of the pipe.

Abstract: The gas detonator is especially adapted for shallow, seismographic, land prospecting. It comprises a circular bottom plate having an inwardly-directed sloping side wall. An annular top plate is mounted over the bottom plate. Means, including a plurality of springs, interconnect and resiliently maintain the plates in touching relation with each other. A housing is mounted over the top plate and forms therewith a detonation chamber. The bore of the top plate serves as the vent port for the detonation chamber. The vent port is normally closed by the bottom plate. Following the detonation of a combustible gas mixture in the chamber, the plates momentarily separate and form therebetween a cylindrical cavity which opens the vent port. A container upwardly extends from and forms with the bottom plate a reservoir which, in use, is filled with water. The spent gases of combustion escape into this water, thereby muffling the sound of the detonator.

Abstract: This invention relates to the recovery of oil from an oil well which normally produces a mixture of oil and water. The invention is carried out by determining the potential free water level in the well bore, draining the oil gravitationally from a point above the predetermined water level, and withdrawing the drained oil.
