Abstract: ABSTRACT     A two step pressure intensifer system made up of three operative piston and cylinder arrangements in coaxial alignment and having a common piston rod to which the pistons of each unit are secured for movement in unison.          The first piston and cylinder unit being operated by application of fluid pressure from an external source, to move the piston rod in a working stroke direction, the cylinders of the second and third units being in open communication for a predetermined distance of movement of the piston rod in the working stroke direction and containing a working fluid medium, the piston of the third unit being clear of the cylinder of the third unit during said predetermined distance and thereafter entering the cylinder of the third unit to close off the communication.  The second piston and cylinder unit being provided with a predetermined pressure bleed.  The system provides a reliable, economical and single pressure intensifier operable over a wide range of source pressures since no predetermined pressure responsive valves are employed.

Abstract: ABSTRACT        A method for testing a magnetizable workpiece for flaws by the magnetic particle inspection method wherein a coating of finely divided, hydrophobic particles is electrostatically applied onto the surface of a workpiece to be tested after which an aqueous suspension of magne-tizable particles is applied over the resulting coating. The magnetized workpiece is then inspected for deposits of magnetizable particles which have become lodged in the flaws.  The hydrophobic nature of the coating repels the water from the suspension, and permits the indications to appear promptly after application of the magnetizable particle suspension.

Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus is disclosed for drilling a pilot hole and subsequently enlarging the pilot hole in earth formation.          A dual concentric pipe string is used for circulating air downwardly through the outer pipe, through a pilot bit and upwardly through the bore hole outside the pipe string to bail cuttings, during drilling of the pilot hole.  The air pressure expands the cutters of an expansible bit while a limited portion of the air supplied cools the cutters.          After the cutters are fully expanded, additional air is utilized to clean and cool the cutters.  Air is returned through the inner pipe of the dual concentric pipe string.          A venturi device is utilized to induce return flow through the inner pipe during enlargement of the hole to vacuum residue when enlargment is completed.  The dual concentric pipe string is made up of lengths of pipe providing threaded, sealed joints.

Abstract: ABSTRACT            Stop-a-Thief is a "passive" theft prevention system for vehicles. It automatically protects the vehicle from being driven away and does not rely on the driver for activation. The owner of the vehicle must by-pass this protection each time he starts his vehicle by pressing down,or closing,a momentary switch. However,when the ignition switch is turned off,Stop-a-Thief is automatically reactivated. This theft prevention is achieved on all 12-volts ignition systems by intercepting the wire that connects the two terminals of the primary circuit between the coil and the distributor and connecting these extremities to Stop-a-Thief.
