Abstract: Abstract A battery separator embossed with a configuration that is neither vertical corrugation or vertical rib and yet in which all of the surface areas of the two separator faces open or slant upwardly except the portions actually directly engaged against a battery plate.  Thus all intended recesses in the faces of the battery separator are open at their upper extremity so that no gas can be trapped by the configuration of the battery separator embossment. Additionally the division portions between the embossed recesses on the positive plate engaging face are in continuous engagement with the positive battery plate from the bottom of the plate to the top of the plate which provides stability to the raised areas of the battery separator that engage the negative battery plate.

Abstract: ABSTRACT OF THE DISCLOSURE:          This invention relates to an improved process for the production of hydrogen fluoride.  In this process, waste materials, particularly waste materials from the electrolytic production of aluminum, such as lining material broken out of the electrolytic cell, are contacted with steam at about 1000 to 1350°C for a recovery of hydrogen fluoride by pyrohy-drolysis in a expanded fluidized bed.  The exhaust gas from the pyrohyclrolytic treatment are then cooled in such a manner that it is not increased in quantity and accordingly that the relatively low hydrogen fluoride concentration is not decreased further.  In accordance with the invention the exhaust gas is cooled by direct contact with solids which are subsequently recooled in a cooler in which their contact heat is recovered.  The exhaust gas and cooling solids are prefe-rably contacted in a suspension-type heat exchanger and the solids are preferably recooled in a multistage fluidized bed cooler.

Abstract: ABSTRACT OF THE DISCLOSURE     A pressure surge relief system for a liquid transporting pipeline, comprising a surge relief line adapted to be tapped from the pipeline.  The relief line includes a valve which is conditioned to open quickly to substantial flow when the pressure in the line exceeds a predetermined safe limit, which is well above the normal pipeline pressure.  When the valve opens, it diverts to a closed receptacle, that quantity of liquid which is necessary to prevent the pressure from exceeding said pre-determined limit.  Hence, in the event of the surge, much of the pressure is absorbed in the liquid and pipe, and just that quantity of liquid which is necessary to relieve pressures of unsafe pro-portions is discharged to the closed receptacle.  The receptacle is pre-charged with a gas to cushion the impact of the surge and also includes means to dissipate energy of the liquid surge and to bring the liquid to a state of quiescence as quickly as possible.  A return duct evacuates the reservoir to the pipeline when the surge subsides.

Abstract: (Case No. 59-1A) ABSTRACT              A hydraulic tensioning device for maintaining a pre-determined amount of tensioning force on an endless drive bolt for the vehicle accessories drive system.  A hydraulic cylinder is adapted to be mounted in a fixed position with respect to the vehicle engine and is operatively connected to the low-pressure hydraulic fluid system of the engine.  A bellcrank mechanism is pivotally mounted on the cylinder and has a bolt-engaging idler pulley rotatably mounted on an extended end of one of the levers.  The other lever is operatively engaged by the cylinder piston which moves the idler pulley into tensioning engagement with the drive belt.  The cylinder has a plurality of discs mounted in a spaced relationship on the piston rod for imparting movement to the rod when acted upon by hydraulic fluid.  Each disc forms a movable forward wall of a separate hydraulic subchamber located within the cylinder. A hollow bore is formed in the rear portion of the piston rod to provide a fluid passage between the spaced subchambers.  The discs and associated subchambers enable a sufficiently large force to be exerted on the piston rod for actuation of the bellcrank from the low pressure of the engine lubricating system.  A check valve is provided in the incoming hydraulic fluid passage of the cylinder and keeps those portions of each cylinder subchambers which are located behind the piston discs filled with hydraulic fluid to maintain a constant predetermined tensioning force on the belt without regard to the operating condition of the engine, and to provide a shock-absorbing damping action for the idler pulley.

Abstract: Abstract of the Disclosure A process is disclosed for preparing slubby strands in which a textile strand is passed either over a surface or through a slubbing tool.  The surface, if employed, may include a plurality of fluid passages positioned therein.  As the strand passes over the surface or through the slubbing tool, high pressure fluid is introduced onto the surface of and through the strand.  The high pressure fluid passes through the strand.  This passage of fluid through the strand causes the strand to twist and bulk along its length to form a slub which is rapidly removed from the working surface of the slubbing surface or tool as a consolidated slub positioned on the strand.  Optionally, varying-fluid pressures may be employed from opposing sides of a single tool to give a more random slubbing effect.  When a surface is employed, the surface may be a moving surface and when the surface includes a plurality of fluid passages, the passages may be vented at a point below the surface.  Various apparatus for carrying out the novel method are disclosed as is the novel strand produced thereby.  The process is described with particular reference to producing strands of glass fibers.
