Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides an apparatus capable of effecting relative movement between the oval-like girth or circumference of a workpiece and tool means while maintaining the planar and radial workpiece surfaces in a fixed plane relative to the tool means as they are exposed thereto.  The apparatus is especially useful in laser welding, and for this use, includes a base in a fixed plane relative to a focusing lens, means for effecting relative translational movement between the base and lens, and bearing and shaft means, including chuck means, for holding the workpiece in proper relation to the lens and for rotating the workpiece about longitudinal axes through the radii of the oval-like workpiece girth.  The relative translational movement between the base and lens is utilized to cause the laser beam to transverse the planar surfaces of the workpiece whereas the rotational motion is utilized to cause the beam to traverse the radial surfaces of the workpiece while maintaining these latter surfaces in the plane established by the planar surfaces during their exposure to the tool means.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for heating recovered crude oil at the site of recovery thereof and injecting at least a portion of such heated crude oil back into the oil formation in order to reduce the viscosity of oil remaining in the oil formation, the invention facilitates recovery of the remaining oil and renders the oil more easily handled through pumping operations. Apparatus according to the invention particularly provides for solar heating of a working fluid circulating through  a closed heat exchange coil disposed within a crude oil storage tank located in proximity to one or more operating wells and normally used for temporary storage of oil pumped from the wells.  Heat energy carried by the working fluid in the closed coil is transferred to the crude oil within the storage tank, the heated crude oil being then pumped back into the oil formation to heat the remaining oil in the formation, the viscosity of the remaining oil being reduced to allow a greater total recovery of the oil in the formation.

Abstract: POWER STEERING GEAR WITH SHORT   PISTON AND FLUID BEARINGS                     ABSTRACT OF THE DISCLOSURE         An integral power steering gear with a valve in the piston is provided having a short piston and cylinder to conserve space and weight.  The input shaft is mounted on a bearing carried by an inwardly projecting annular portion on the bearing cap.  The projecting portion mates with a recess in the end of the piston when the piston is moved to the full extreme in that direction.  The valve guide pin has been relocated at the input shaft end of the valve where maximum support of the valve is realized and improved reversibility of the valve under all conditions is gained. In the bearing cap, both a high pressure seal and a low pressure weather seal are provided.  An insert ring between the two seals serves as backup to the high pressure seal.          In an alternative embodiment, the insert ring may be tapered toward the inside of the gear to allow use of a thin wiper-type seal.  Lubricating grooves in the piston adjacent the output rack provide fluidized bearings to counteract the force of the fluid bearing provided on the top of the piston at the pressurized input slot.  Dual feed passageways extend-ing to opposite ends of the piston have connecting ports drilled from opposite sides of the piston to add further lubrication, but also prevent cross-bleeding between the ports.

Abstract: ABSTRACT OF THE DISCLOSURE         Electromagnetically operated contactor or relay in which the stationary magnetic core and operating coil are mounted in a base section and the movable armature and the switching elements are mounted in a main frame section.  With the two sections assembled together the pole face structures of the stationary core abut reference surfaces in the main frame section.  When the operating coil is energized, the armature moves into contact with the pole faces of the stationary core.  Thus, since the reference surfaces in the main frame section determine the position of the stationary core pole faces and hence the position of the armature when the core is energized, the positions of all movable elements are determined solely by dimensions of the main frame section independently of the base section.

Abstract: ABSTRACT        A lighter having few moving parts. A lid assembly which closes a fuel supply and which rotates a flint wheel can be controlled by the same spring or other resilient means which bears a flint against the flint wheel.  The lid assembly has one or more cams which bear against cam guides; the shape of these cams and guides are such that the spring produces a turning moment on the lid assembly which keeps the lid assembly closed when in the closed position and open when in the open position.          A second spring can be provided which acts directly to bear the cams against the cam guides, thereby increasing the turning moment on the lid assembly without increasing friction between the flint and the flint wheel.  The cam guides can be formed as part of the body of the lighter, guides, or they can be provided in a separate structure housed within the lighter body guides.
