Abstract: ABSTRACT OF THE DISCLOSURE Crude oil remaining in a subterranean formation is recovered through the injection of a microemulsion comprising an oil, i.e. a refined or crude oil, an aqueous medium and as a surfactant, a C8-16 orthoxylene sulfonate. The aqueous medium is preferably a brine having a salt concentration of up to about 2-1/2% by weight, although increased brine tolerance can be achieved by inclusion of a cosurfactant within the microemulsion.  When utilized in the secondary or tertiary recovery of crude oil, the microemulsion is prefer-ably followed by thickened water and thereafter unthickened water injected into and through the subterranean formation.

Abstract: ABSTRACT         The present invention relates to an improvement in a known air burst munitions simulator projectile having (a)  a munitions payload container (b)  means mounted on the container to contain an explosive to cause the container to burst and (c)  an obturator for the container and means mounted on the con-tainer to contain explosives.  The improvement is in the container and obtura-tor being formed wholly by a light plastic material which shatters when the container is caused to burst.  In addition, there can be provided a launcher for the projectile of this invention, having a muzzle formed from an expendable material such as cardboard.  The present invention provides an inexpensive projectile formed from a light material.  This light material in place of metal components reduces the missile hazzard from the shattered projectile considerably.  In addition, the projectile shatters extensively rather than just breaking up.  The launcher of the present invention is also inexpensive and thus can be an expendable component if one desires to avoid the procedure of decontaminating the launcher following its use.  The launcher is also less heavy than known launchers and consequently easier to handle.

Abstract: ABSTRACT OF THE DISCLOSURE           Plywood is made  by continuously propelling a liquid plywood glue in unfoamed condition at a predetermined flow rate, continu-ously foaming the flue as it is propelled, and continuously ex-truding or otherwise applying the foamed glue to the surface of a plurality of wood veneers.  The flow rate of the unfoamed and foamed glue is maintained substantially the same on a unit weight of liquid glue per unit time basis.  The veneers then are laid up in-to a plywood assembly and pressed, whereupon the pressure breaks the fo?? and unites the veneers.  The method is applicable gener-ally to the production of laminar products by the application of a foamed liquid to a solid surface.

Abstract: ABSTRACT OF THE DISCLOSURE         A cast bushing having a capacitor structure which includes concentrically positioned capacitor sections.  Each capacitor section includes a spacing member which helps to maintain the distance between the conducting portions of the capacitor sections during the casting process.  The spacing members consist of a tapered cylindrical non-conductive mesh around which another mesh member and a conductive foil are positioned.  The diameter of the smaller opening of the tapered mesh permits the insertion of a similarly constructed but smaller diameter capacitor section inside the tapered mesh to form concentric capacitor sections.  The rigidity of the tapered portion of the mesh maintains the desired distance between the conducting foils of the two concentric capacitor sections.  Two-piece mandrel assemblies are used to construct each capacitor section.

Abstract: Abstract of the Disclosure.           The invention provides for an internal combustion engine that causes a radial flow of combustible gases about the axis of a torroid or annulus cylinder.  The cylinder will have an intake and exhaust port, together with provision for a spark plug and/or fuel injector.         The cylinder encloses four pistons.  Two pistons are connected diametrically opposite to each other to a forward driving disc.  The two remaining pistons are similarly connected to a rear driving disc.  Provision is also made within the cylinder wall for the intrusion of the forward and rear driving discs.  The discs are respectively connected to an inner and outer driving shaft that are independently rotatable about the axis of the cylinder.              The coaxial shafts thus described pass along the axis of the cylinder to a rhomboid and power take off unit.  Within this unit radial arms connected to the inner and outer shafts are pinned centrally to the links of a rhomboid mechanism.  The four links of the rhomboid mechanism have rollers at their pinned ends and these rollers are caused to follow the contour of a stationary can within which the rhomboid mechanism is contained.  A rotational displacement about the axis of the engine of the rhomboid mechanism leads to an angular displacement of the links. This displacement is translated to the inner and outer driving shafts and hence by firm connection to the pistons.  The cam being of the desired contour, causes the pistons to move with a compound motion within the cylinder whereby any pair of adjacent pistons not only rotate about the axis of the cylinder but also move with an angular harmonic motion with respect to each other.            Thus there exists within the cylinder, separated by the pistons, four variable cavities.  These spaces or cavities which in turn increase whilst exposed to the intake port, decrease for a compression of gas, increase for the expansion of hot gas, and decrease whilst exposed to an exhaust port, causing the equivalent of four power strokes per revolution of the engine.                Unlike a number of proposed rotary engines, the power from this engine is not taken directly from the inner or outer shaft, but from the rhomboid mechanism to a power take-off coupling and a separate final drive shaft.

Abstract: ABSTRACT OF THE DISCLOSURE       An electronic watch wherein pulses from a high-frequency standard are converted by a frequency divider into low-frequency timing pulses which are supplied to a stepping motor to advance the hands of the time display.  In order to automatically effect a rapid correction of the seconds hand display when it deviates from precise time, a system is provided that includes an actuating element accessible to the user of the watch and operatively coupled to a switch connected through a reset line to several of the last stages of the frequency divider to effect a reset thereof upon activation of the switch.  Also reset when the switch is activated is a reference counter supplied with pulses by the frequency divider.  The divider feeds pulses by way of a logic circuit to the stepping motor and to a synchronous counter which is maintained in synchronism with the time display.  A com-parator circuit determines whether a deviation exists be-tween the two counters and acts to govern the number of pulses per unit of time that the logic circuit supplies to the stepping motor and to the synchronous counter to an extent correcting for the deviation.  The logic circuit is so connected to the outputs of the resettable divider stages that the transmission of pulses from the divider to the two counters can only be carried out during a pulse transfer period whose duration is no longer than the last quarter of the longest duration pulse period of the di-vider.  Resetting of the frequency divider is inhibited during the transfer period.

Abstract: Abstract of the Disclosure A method of filling a press mould with a pourable but at most limitedly flowable substance, e.g. fibrous material and a thermosetting binder, for producing a pre-form or a finished three-dimensional article by pressing, in which a forming space of a configuration substantially corresponding to that of the preform or article to be made is defined between a perforated bottom of a container for the substance and the lower mould part and vibrating the perforated bottom or the container to introduce and compact the substance into the forming space to the required config-uration and depth.  The apparatus for carrying out the method comprises a removable container for placement over the lower part of the press mould having a grating or sieve at its bottom.  Conventional vibrating means are mounted on or connected to the container with the inter-position of resilient damping means for causing vibratory movements in one or more directions to cause a dosed amount of the sub-stance to be admitted to the mould bottom in the desired amounts.  The method and apparatus can be used to produce a preform or pre-pressing in the cold for subsequent finish pressing in a heated mould or to produce the finished article in one and the same press mould.
