Abstract: ABSTRACT OF THE DISCLOSURE            The method includes circulating steam, solvent or fluids through the sand while constantly agitating the sand to scrub and wash the oil free whereupon the oil is carried back to the surface.  A vibrating probe assembly is utilized which is highly manoeuverable and which fluidizes the sand immediately surrounding same thus facilitating the movement of the probe and assisting in the scrubbing and separating action of the solvents or steam upon the sand.  The probe in-cludes means for extending same into the sand to the bottom of a well bore so that the vibration in conjunction with the probe configuration moves the probe through the sand in a horizontal plane or, if desired, up and down at an angle from the horizontal.  The voids remaining in the clean sand are filled with water so that the probe floats on the sur-face of the water.  The oil which has been separated from the sand floats on the water to the well bore and thence is elevated to the surface by the pressure of the steam, solvent or fluid circulation.

Abstract: SYSTEM FOR TELEMETERING WELL         LOGGING DATA                SPECIFICATION                 ABSTRACT OF THE DISCLOSURE     In particular embodiments described, a telemetering system for well logglng receives and temporarily stores blnary-coded parallel data in a downhole memory unit and continuously interrogates and transmits the stored data to the surface at a fixed rate in binary-coded serial format. The system thus accommodates high instantaneous data-generation rates, such as are encountered, for example, in gamma ray spectroscopy tools, without loss of information on the cable. The stored data is compacted, by suppressing leading zeros in data words, prior to appllcation to the cable.   This affords faster memory read-out and reduces cable transmission time. The data word format and signal format utilized on the cable provide low error-rate data flow to the surface, as well as facilitating the maintenance of synchronous operation between downhole and uphole functions.  In one embodiment, the system also includes multlplexed access to the memory unit for data generated both at random and at predetermined intervals, there-by enabling different types of information to be obtained with a single logging tool.

Abstract: HYDRAULIC SYSTEM Abstract of the Disclosure An electro hydraulic system for controlling a hydraulic function includes a pump and a reservoir connected to the function through a manually operable, electro-hydraulic control valve.  The valve is positionable to either side of a neutral ports blocked position and may be held to one side by the engaging of a spring loaded detent.  The detent is disengaged by an electrical signal produced by a comparator when a preset, operator-controlled, limiting signal is equalled by a feed back sensor signal propor-tional to the output of the function.  The system will allow initial activation of the valve to provide continuous operation of the function until the limiting input is reached at which time the function will be stopped. The system further provides manual override of the electrical control system to permit operation of the valve when the feedback signal is greater than the limiting input signal.

Abstract: ABSTRACT OF THE DISCLOSURE         There has been developed end units for cans of the easy opening type wherein end panels of the end units are provided with patterns of holes to facilitate the dis-pensing of a product.  The holes are closed by means of strips, preferably formed of plastics material, overlying the holes and being bonded to the metal of the end units adjacent the holes.  It is preferred that the bonding of the strips be effected by heat.  A special induction heater has been constructed which induces into the metal of the area to where the strips are to be bonded electrical energy which results in the heating of the metal.  The heater is particularly constructed so as to compensate for the holes in the metal of the end units and thus a uniform heating of the metal over the area to which the strip is to be applied can be effected.

Abstract: ABSTRACT OF THE DISCLOSURE    A substantially noncorrosive solution of cuprammonia low carboxylate complex of copper carboxylate and ammonium carboxy-late is described wherein said complex is fungicidally and bactericidally effective when diluted with water in an amount of 3 to 200 parts of water per part of complex solution.  The dilution causes the hydrolysis of the complex and the precipi-tation of a finely divided flocculent form of fungicidally and bactericidally active copper values.  When the flocculent precipitate is applied to the locus of bacteria or vegetation on which fungus is to be controlled, the flocculent precipitate forms a gelatinous coating of copper values which adhere teneciously to the locus of application or vegetation where applied.  Once dried, the coating adheres as a coating which is not readily removed by moisture or rainfall.

Abstract: Abstract of the Disclosure To enable a high-speed machine to process (for instance interconnect and reel) only acceptable, predeterminedly ordered electronic components after appropriate test, velocity changing mechanism actuatable by a continuouslyoperable conveyor of the machine is provided to shift components to and from a testing unit and relative to their respective successive locations along the conveyor.  Only failure of a component to qualify at the test unit automatically stops the conveyor, and that enables an operator to take corrective action by satisfactory completion of a test on a replacement component which then is preferably manually located in its proper sequence on the conveyor prior to re-starting of the machine.  Accordingly, except for the usually uncommon short interval when an attendant may need to make substitution for an unsatisfactory component which has been detected, the invention enable rapid processing of assuredly reliable components and their intended sequence is verified.
