Abstract: ABSTRACT         A resiliently squeezable container is disclosed which is partitioned by a resilient deformable membrane into two chambers, an ingredient chamber, which communicates through an ingredient discharge orifice to the outside, and an air chamber which communicates through a simplistic reclosable valve to the ambient atmosphere.  The reclosable valve is such that the pressure within each chamber is held in equilibrium.  Thus, on squeezing of the container ingredients are exuded from the ingredient chamber and on release of the container (recovery) air enters through the reclosable valve into the air chamber to re-establish equilibrium between chambers within the container.  Thus, by cyclically squeezing and releasing the container, ingredients in the container are instantaneously discharged during each squeeze portion of the cycle.  The invention resides in the reclosable air valve which utilizes as the movable element of the valve a portion of the resilient deformable membrane.  Also disclosed are novel ingredient discharge orifice which prevent air from entering the ingredient chamber.

Abstract: Abstract of the Disclosure A vibratory, force transducer (4) includes a pair of elongate, generally parallel bars (8, 12) coupled toge-ther at their ends (16, 20) in a type of double-ended tuning fork arrangement.  The bars (8, 12) each have a thickness of t, a width of w, and a length between fixed ends of L.  The distance separating the points where the bars (8, 12) are coupled together is m.  Apparatus (32, 26, 40) is provided to cause the bars (8, 12) to vibrate in a transverse direc-tion and in substantially 180° phase opposition.  Apparatus (44) is also provided for determining the frequency of vibration of the bars (8, 12) so that when the bars (8, 12) are subjected to either compressive or tensile forces along the longitudinal axis of the bars (8, 12), the magnitude of such forces can be readily determined by simply determining the magnitude of the frequency change.  The values of w and t are selected so that 0.4 t/w  4, and this reduces the likelihood of buckling the transducer (4) when it is sub-jected to compressive forces while also maintaining a con-figuration which is relatively easy to fabricate using a photolithographic process.  The values of t, w, L, and m are selected so that various spurious modes of oscillation of the transducer (4), which causes a reduction in the mechani-cal Q and thus an erroneous reading of applied forces, are avoided.  The disclosed selection processes for t, w, and L may be applied also to single beam (60) flexure mode trans-ducers to avoid spurious modes of oscillation while main-taining a configuration which is relatively easy to fabri-cate using photolitographic processes.

Abstract: DOWNHOLE STEAM GENERATOR WITH IMPROVED  PREHEATING, COMBUSTION AND PROTECTION FEATURES              ABSTRACT OF THE DISCLOSURE An apparatus for generation of steam in a bore-hole for penetration into an earth formation wherein feedback preheater means are provided for the fuel and water before entering the combustor assembly. First, combustion gases are conducted from the com-bustion chamber to locations in proximity to the water and fuel supplies.  Secondly, both hot combustion gases and steam are conducted from the borehole back to the water and fuel supply.  The water used for conversion to steam is passed in a countercurrent manner through a plurality of annular water flow chan-nels surrounding the combustion chamber.  In this manner, the water is preheated, and the combustion chamber is cooled simultaneously, thereby minimizing thermal stresses and deterioration of the walls of the combustion chamber.  The water is injected through slotted inlets along the combustion chamber wall to provide an unstable boundary layer and stripping of the water from the wall for efficient steam genera-tion.  Pressure responsive doors are provided at the steam outlet of the combustor assembly.  The outlet doors and fluid flow functions may be controlled by a diagnostic/control module.  The module is positioned in the water flow channel to maintain a relatively constant, controlled temperature.

Abstract: The present invention relates to a method of controlling and regulating operational parameters of a machine for continuously casting bands between cylinders, allowing adhesion to be avoided. This method comprises considering as parameters the torque exerted on one or other of the cylinders for moving the band on and comprises permanently comparing the frequency of the variations in the torque measurement with a reference frequency. When the variation frequency is greater than the reference frequency, the casting speed of the machine is reduced and/or the lubricant flow rate is increased until the variation frequency is again lower than the reference frequency. The speed of the casting machine is then increased as long as the variation frequency remains below the reference frequency.
