Abstract: Abstract of the Disclosure Horizontal damping elements are arranged in the water distribution chamber to damp out wave action in the water flowing to the individual compartments formed by vertical baffles.  The damping elements may be integral with the baffles to form one-piece members or may be formed of flat plates separate from the baffles.  The dampening elements prevent periodic fluctuations from occurring in the water streams from which steam is produced and thus fluctuations in the amounts of generated steam.

Abstract: Abstract of the Disclosure A vortex cleaner for separating a gaseous or liquid suspension, as for instance a paper pulp suspension, into fractions comprises an elongate vortex chamber which has a circular cross-section and tapers gradually, over at least part of its axial length, towards one axial end of the chamber. The larger end of the vortex chamber is provided with a tangential inlet for the suspension to be treated and an axial  outlet for a lighter fraction of the treated suspension. The smaller end of the vortex chamber is provided with an axial outlet for a heavier fraction of the treated suspension. The tapering portion of the vortex chamber consists of a plurality of chamber sections with circular cross-section, which are disposed one after the other in axial direction and are in direct communication with each other. Each such chamber section has a smaller diameter than the immediately preceding chamber section, as seen from the larger end of the vortex chamber, and has its center displaced laterally relative to the center of the immediately preceding chamber section as well as relative to the center of the immediately following chamber section, whereby a crescent-shaped ledge facing towards the larger end of the vortex chamber is formed at the transition from each chamber section to the immediately following chamber section. The chamber sections may be circular cylindrical or, preferably, truncated conical and divergent towards the smaller end of the vortex chamber.

Abstract: PROCESS FOR MAKING SOUND INSULATION COMPONENTS            Abstract of the Disclosure A process for making composite contoured sound insulating panels of a type suitable for use adjacent to structural panels of automobile vehicle bodies, which in accordance with one embodiment of the present invention, comprises forming a fibrous pad incorporating controlled amounts of a heat curable thermosetting binder and a heat softenable thermoplastic binder distributed in a controlled manner therethrough.  The pad is subjected to a preliminary curing step to bond the fibers together into an integral mass, whereafter a dense liquid vinyl plastisol coating is applied to at least one face surface of the pad, which thereafter is heated to effect a fusion of the coating into a heat softened integral layer, effecting a simultaneous heat softening of the thermoplastic binder, whereafter the heated pad is placed between appropriately contoured mold surfaces and is compressed to impart a preselected contour thereto and localized emboss-ments therein and a desired surface finish to the plastisol layer, while simultaneously cooling the pad to effect a rigid-ification of the thermoplastic binder and the layer so as to retain the composite pad in the preselected contoured and em-bossed configuration.  In accordance with an alternative em-bodiment of the disclosed process, the pad is subjected to a preliminary molding step, followed by the coating step, and is subjected to a final molding step after the plastisol coat-ing has been fused at an elevated temperature.  The step of molding the plastisol layer is performed employing a subat-mospheric pressure to achieve improved definition in the contour and texture of the molded face surface.

Abstract: ABSTRACT OF THE DISCLOSURE In a handling hook assembly for use in hoisting various loads by means of a sling, there is described an improved hook assembly wherein the locking lever attaches and detaches auto-matically when the hook is placed under load or when the hoist line is slackened respectively without the use of actuating ele-ments such as springs.  Known handling hooks require manual actua-tion to either close or open the locking lever, presenting a signi-ficant danger to the hands of the operator.  In this invention, a hook member is formed with a gap to receive a sling or other load.          A locking lever is pivotally mounted on the long arm of the hook member so as to pivot inwardly of the hook member.  An aperture is formed in the lever adjacent the pivoted end of the lever to receive the hoisting cable and is so located that the forces exerted by loading exert a moment about the pivot thereby causing the lever to pivot into its locked position.  The free end of the locking lever is formed having a claw-shaped end portion with two claws, each of the claws having laterally extending engaging surfaces to engage with laterally extending shoulder portions formed into the opposing end of the hook member.  When the hoist line is slackened, the locking lever disengages and pivots inward-ly and away from the opposing end of the hook.

Abstract: POWER STEERING VALVE AND METHOD OF MAKING THE SAME                   ABSTRACT OF THE DISCLOSURE    An improved power steering valve has a sleeve which circumscribes an inner valve member.  An end mill or other rotary cutting tool is utilized to form axially extending grooves inside the valve sleeve.  When the end mill is forming the grooves inside the valve sleeve, the axis of rotation of the end mill extends at an acute angle relative to the central axis of the valve sleeve.  This results in a groove being formed with axially sloping end surfaces.  In order to tend to maximize the compactness of the construction of the valve sleeve, fluid passages or holes are drilled along a sloping path from annular grooves on the outside of the valve sleeve to the sloping end surfaces of the axial grooves inside the valve sleeve.  In addition, the compact construction of the valve sleeve is further promoted by forming some of the annular grooves with sloping bottom surfaces so that these grooves are relatively deep.  This enables the width of these grooves to be reduced without reducing the capacity of these grooves to accommodate fluid flow.
