Abstract: ABSTRACT OF THE DISCLOSURE      A salt substitute composition comprising:   a) from about 70% to about 98% by weight potassium chloride, b) from about 1% to about 20% by weight of a non-reducing sugar, preferably sucrose, c) from about 0.3% to about 15% by weight of an edible organic acid, preferably adipic acid, d) from about 0.5% to about 10% by weight of a glutamate salt, preferably potassium glutamate, and from about 0.15% to about 5% by weight of an anti-caking agent, preferably tricalcium phosphate, said percentages adding up to 100%, is stable and palatable even after storage at high temperatures over an extended period of time.    Use  of  a  non-reducing  sugar  achieves  the beneficial  effects  of masking  the undesirable  bitter taste of the potassium ion without reacting with the glutamate salt as do reducing sugars.

Abstract: A PROCESS FOR IMPROVING WATERFLOOD PERFORMANCE           IN HETEROGENEOUS CLAY-SENSITIVE FORMATIONS     ABSTRACT    A freshwater containing polyvalent cations and relatively few or no monovalent cations is injected into a heterogeneous clay-sensitive sub-terranean hydrocarbon-bearing formation via a well.  The polyvalent cat-ion solution displaces the saline connate water in the near wellbore environment and contacts a first water-sensitive clay. The polyvalent cation solution exchanges polyvalent cations for monovalent cations in the first clay causing little clay damage while producing a monovalent cation solution which is thereafter displaced  into  the  far wellbore environment.   The monovalent cation solution contacts a second water-sensitive clay in the relatively highly permeable zones of the far well-bore environment to effect clay damage and reduce the permeability of the highly permeable zones in the far wellbore environment.  The process results in improved waterflood sweep efficiency.

Abstract: ABSTRACT          A  device utilizing energy conversion into heat by eddy currents for braking the descent of a refugee as from higher stories of a building in the event of a fire or other emergency.  Included is a payoff reel rotatably mounted on a frame for paying off wire rope.  The payoff reel is coupled via overdrive gears to a rotor of electrically conductive material which also is rotatably mounted on the frame and which rotates at a greatly increased speed in response to the rotation of the payoff reel.  A permanent magnet or mag-nets of generally annular configuration are secured to the frame in an opposed relation to the rotor for inducing eddy currents therein upon rotation of the payoff reel.  The in-duced eddy currents convert the energy of the revolving pay-off reel into heat.

Abstract: Abstract A main pump (rotary vane pump 1) and a secondary pump (radial piston pump 2) are driven by way of a common shaft (3), a cam ring (30) being used to drive the secondary pump. The cam ring is coupled to the shaft (3) by way of a shear pin (33). If the auxiliary pump locks, the shear pin fractures and the cam ring (30) can rotate relative to the shaft (3). In that case, the fracture portions of the shear pin (33) are driven into their respective bores (34, 35), thereby avoiding excessive friction and overheating. Therefore, the main pump can continue to operate in spite of the failure of the auxiliary pump.            (Figure 1)

Abstract: ABSTRACT     Strain gauge transducers are fitted to the leading and trailing faces of a vehicle axle between each wheel and the adjacent suspension.          They have strain gauges in balanced bridge forma-tion and their orientation is such that their outputs can be combined in one circuit to produce an indication of axle loading and in another circuit to produce an indication of torsion, these signals not being influenced by irrelevant strains.  The infor-mation from the transducers can be combined to indicate individual axle loading, and total loading, and the torsional signal can be used in an anti-skid braking system.

Abstract: ABSTRACT     A thread forming screw made from a blank which has a tip with an assymetrical cross-section comprised of two opposite-ly disposed inner surfaces which gradually merge with two oppo-sitely disposed outer surfaces.  The inner surfaces may be arcuate or generally flat or a combination thereof.  The inner and outer surfaces are generally parallel to each other and to the axis of the screw so that, when rolled, the tip has generally fully formed sharp crested threads which gradually deform work-piece material upon insertion and axially advancing rotation in a bore.  The reduced frictional contact is achieved because of sub-stantial unthreaded portions on the inner surfaces.  Improved gripping action results from the formation of full threads which extend substantially the full length of the fastener.

Abstract: ENHANCED EXTRUSION COOLING Abstract of the Disclosure This invention relates to apparatus for controlled cooling of an extruded plastic product. As the product exits the extrusion die, it passes through an elongated shell. The shell surrounds the die at its inner end and extends outward-ly along the extrusion. A seal ring at the outer end of the shell engages the exterior of the extruded product; the shell, seal ring, and product define an annular cooling chamber through which a coolant is circulated through the cooling chamber, the coolant exiting through an annular cooling chamber extension in the die. For a hollow extruded product, the apparatus further includes an internal cooling tube that extends axially through the interior of the hollow product. The tube ends at a seal cap that engages the internal surface of the hollow product. The tube and seal cap define a second, internal cooling chamber through which coolant circulates; the coolant enters through the end of the tube opposite the seal cap and exists through an annular recess in the die.
