Abstract: A self-propelled wheeled vehicle has a load receiving tank with the driving wheeled suspension system and the driven steering control system directly attached to the load receiving tank. The prime mover and power transmission system is also attached to the tank and interconnected with the driving wheels. An operators cab is attached to the forward end of the load receiving tank. A front loader mechanism is integrated with a top front load receiving opening in the tank and the closure therefor such that movement of the closure simultaneously lifts an interconnected load container, raises same and dumps the load into the load receiving tank and vice-versa. The chassiless vehicle is applicable to rear loader and side loader use.

Abstract: A system for exchanging thermal energy between a fluid medium and the earth is provided employing a number of boreholes drilled vertically in the earth spaced apart by adjacent intervals. An upflow conduit and a downflow conduit are placed in parallel relationship within the boreholes and connected at their lower ends. At the top of each borehole there is a header providing means to conduct fluid through the conduits in each borehole in a parallel or series arrangement. In each of the headers there is a partition dividing the flow of fluid passing downwardly into the borehole from the flow of fluid passing upwardly out of the borehole with a vent in the partition so that air which might otherwise be trapped in the verical conduits can by vented to prevent airlock of the system.

Abstract: A security housing for surrounding a valve attached to a storage tank comprising a pair of hinged clamshell structures (e.g., hollow semi-cylindrical enclosures) that are also pivotally hinged to the storage tank adjacent to an outlet pipe with valve such that the clamshell structure when closed surrounds the valve, yet swings away from the valve to allow access thereto. The security housing is further equipped with an opening which allows manual access to a padlock and padlock eyelets on the interior of the housing. Such a structure is useful to prevent unauthorized access to crude oil stored in the oil field and the like.

Abstract: A vehicle undercarriage spare tire carrier having a roll bar secured adjacent the storage position of the tire, a pulley assembly secured on the rear bumper of the vehicle, a lever arm pivotally secured to the rear bumper of the vehicle in spaced relation with respect to the pulley assembly, a bracket removably securable to the wheel of the spare tire, a flexible cable secured between the bracket and the lever arm and passing over the roll bar and around the pulley assembly whereby pivoting of the lever arm in one direction lowers the spare tire from the storage position for releasing of the tire for retrieval thereof, and pivoting of the lever arm in an opposite direction pulls the tire into the storage position thereof, and a latching bracket secured to the rear bumper of the vehicle and engagable by the lever arm for locking the lever arm in the position thereof which locks the tire in the storage position.

Endogenous endorphins are disclosed as the agent for stimulating the immune system.

Abstract: This describes a centrifugal separator for fluid and solid mixtures. The rotating centrifuge assembly includes a structure of two rotating circular cones having transfer veins in which the separation takes place in the veins between the two cones. The cross-sectional area of each such vein increases linearly from the bottom to the top. At the top of the transfer veins there is a dense material transfer vein and a light material transfer vein. One discharge vein is an opening which is slanted backwardly from the motion of the rotating centrifuge assembly to the outside circumference of the centrifuge assembly while the second opening is to the inner vortex of the centrifugal assembly. The inner vortex is connected to a vortex pump which removes the least dense material.

Abstract: In the combustion of waste mineral-bearing liquid streams, an improved type of construction for the combustion chamber, for the combustion of waste mineral-bearing liquid streams which permits continuous removal of solid particulate waste. An annular water channel is fitted inside of the outer shell of the combustion chamber at the bottom. The bottom of the chamber is closed off with a funnel-shaped, inverted conical floor, having a drain outlet at its center. An opening is provided in the side of the combustion chamber just above the bottom, for the exit of downflowing products of combustion. Water is supplied to the annular channel and flows through a longitudinal gap in the inner wall, to fall onto the funnel-shaped floor plate, to wash down all of the particulate matter that collects on the bottom plate, into the drain. Thus, the waste is removed as it is formed.

Abstract: An apparatus is provided for determining the consistency of a cement slurry under varying temperature and time conditions. A liquid containing vessel includes a shaft extended from the bottom rotated by a motor supported exteriorally of the vessel. Within the vessel a cylindrical slurry cup is removeably supported for rotation by the shaft in an upright coaxial manner. Received within the slurry cup is a paddle having vertical portions in proximity to the interior wall of the slurry cup. The paddle has an upwardly extending coaxial shaft. Mounted in an opening in the top of the vessel is a potentiometer cup having a potentiometer in a plane perpendicular the shaft axis. A coiled spring also in a plane perpendicular the shaft has one end affixed to the paddle shaft and the other end secured to the potentiometer cup. A wiper arm extends from the shaft to the potentiometer.

Abstract: A portable pipe fusion apparatus for attaching plastic side wall fittings e.g. tees, branch saddles to a plastic pipe of selected composition. This apparatus comprises a base plate with means to rigidly clamp the base plate to a pipe main. Two parallel, spaced support rods attached to the base plate at one end, and to a support plate across the other two ends. Movable clamp means guided to slide along the support rods with the axis of movement intersecting the axis of the pipe main. The movable clamp means is adapted to be attached to and hold various of the side wall fittings rigidly, so that the axes of the fittings intersect the axis of the main pipe. Drive screw means held in a quick release split nut means on the support plate, will force the movable clamp in the direction to contact the transverse pipe main. A hydraulic load cell is interposed between the drive screw and the movable clamp with an indicator which continually reads the force being applied between the moving clamp and the pipe main.

Abstract: Novel transformation toughened ceramic compositions comprising finely divided ZrO.sub.2 -HfO.sub.2 solid solution particles dispersed in a Al.sub.2 O.sub.3 -Cr.sub.2 O.sub.3 (alumina) or 3Al.sub.2 O.sub.3.2SiO.sub.2 -3Cr.sub.2 O.sub.3.2SiO.sub.2 (mullite) solid solution matrix phase. It is found that increased hardness and modulus associated with higher relative Cr.sub.2 O.sub.3 content (e.g. 20 mole %) in the matrix phase and increased fracture toughness associated with higher relative HfO.sub.2 content (e.g. 10 to 20 mole %) in the disperse phase represent viable and improved ceramic compositions. Such transformation toughened ceramic compositions are considered useful in superhot light diesel engine applications, high temperature gas turbines and ultrahigh temperature ceramic heat exchangers.
