Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for producing oil from a subsurface formation containing both oil and water is disclosed. The oil and water are separated downhole within the well with the separated water being conveyed through a well bore and discharged into a disposal formation without raising it to the surface of the well, unless the pressure in the dispersal formation is excessive. The oil is separately conveyed through the well bore to the surface. Separation of the oil and water is carried out by a separator assembly which includes an outer shell having an upper end fitted for connection to a pump intake, a lower end having perforations for admitting formation fluid, a centrally disposed collector tube extending through the shell and dividing the shell into a central flow passage and an annular flow passage, and a laminated filter element disposed in the annular flow passage and convolutely wound around the collector tube. The filter element includes first and second semipermeable membrane sheets which are wettable only to water, a porous substrate sheet interleaved between the first and second semipermeable membrane sheets, and a perforated spacer element interleaved between the adjacent semipermeable layers and wound in convolute relation therewith. Formation fluid is pumped through the space provided by the spacing element with the water phase permeate being collected and conveyed through the collector tube and the remaining crude oil phase fluid being conveyed through the spaces between the semipermeable layers.

Abstract: ABSTRACT OF THE DISCLOSURE         Process for producing metal-resin composite, and the composite resulting therefrom, are provided.  The process comprises providing a solution or dispersion of a resin, for example, an epoxy resin, said solution or dispersion having dispersed therein at least one particulate metal compound, for example, an oxide, of the Group I A and II A metals of the Periodic Table, the amount of metal compound being 1-500 parts by weight per 100 parts by weight of resin, then coating the solution or dispersion on a metal substrate and heating the coated substrate to evaporate the solvent for the resin and cure the resin.  The resultant metal-resin composite is cor-rosion resistant, especially under acidic conditions, since the resin layer having the Group I A or II A metal compound dispersed therein serves to control the pH on the surface of the metal substrate to within the range from 4 to 12 under acidic conditions in the atmosphere surrounding the metal-resin composite.

Abstract: Abstract of the Disclosure A pneumatic fastener applying tool fea-turing a self-cycling control valve with one moving port.  A trigger actuated valve sets the cycling valve in motion.  The cycling valve alternatively pressurizes and vents the working piston of the fas-tener tool.  A valve stem is positioned by an inte-gral reciprocating piston.  The position of the reciprocating piston is determined by the balance of forces between a biasing spring tending to vent the working piston and a pressure-force tending to pres-surize the working piston.  Two flow paths, internal to the valve stem, determine the pressure applied to the reciprocating piston.  One path pressurizes the reciprocating piston.  Another path vents the reciprocating piston.  Postive feedback of air pressure from the working cylinder positions the reciprocating piston and valve stem so as to vent the reciprocating piston when the working piston is vented and to pressurize the reciprocating piston when the working piston is pressurized.  Releasing the trigger actuated valve holds the cycling valve in place and prevents further operation of the fastener tool.

Abstract: Hydrostatic Transmission Having an Overspeed Control Abstract An underspeed actuator is connected to the displacement control for controlling the dis-placement of a variable displacement pump of a hydrostatic transmission in response to the pressure differential between low and high pressure control signals wherein the pressure differential is directly proportional to the engine speed.  An overspeed control valve means is connected to the low and high pressure signals and decreases the pressure level of the high pressure signal received by the underspeed actuator in response to the pressure differential exceeding a predetermined magnitude.  This reduces the displacement of the variable displacement pump thereby controlling the amount of engine overspeed caused by the hydrostatic transmission driving the engine when the vehicle is descending a steep hill.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus is provided for determining gas tension in a liquid.  Liquid is withdrawn from a reservoir by a pump which also serves to pump a gas used for thermos-tatting purposes. The gas is entrained in the liquid at a junction, and the gas and liquid then passes through a coil.  The thermostatting gas is then detrained at a junc-tion and pumped away by the pump.  The thermostatted liquid enters a chamber where a reaction may take place in which the tension of gas (for example oxygen) varies.  The varying gas tension in the chamber is detected by a sensor.          One use for the apparatus is in a glucose analyzer which uses a glucose oxidation reaction.
