Abstract: ABSTRACT OF THE DISCLOSURE         Combinations of sodium chloride or potassium chloride with certain other salts provide a greater degree of water binding in meat products than they would be expected to have based on Raoult's Law.  In addition, these salt combinations provide highly palatable products such as chicken, ham and shrimp when rehydrated prior to consumption.  Preferred salt combinations contain sodium chloride and alkali metal citrates in a weight ratio of from 3:2 to 2:3 at a level of from 6 to 13% based on the total weight of the product which contains from above 30 to 45% water.  m e preferred process includes the steps of infusing the meats with an aqueous solution of the salt combinations and drying the infused meats to the desired moisture under conditions which avoid surface hardening.

Abstract: COMMUNICATION SYSTEM INTERFACE CIRCUIT                         ABSTRACT A communication system includes a mobile station, a plurality of base stations and a central terminal.  Each base station converts RF signals from the mobile station to AF signals.  The AF signals are carried over a balanced line to the central terminal.  Each base station generates a DC voltage signal whose level is representative of the level of its received RF signal.  The central terminal includes means to monitor DC current levels, from each base station, on the balanced line and select that base station producing the highest DC current. The unique interface circuit senses the base station generated DC voltage, which is referenced to a fixed ground potential, and produces a corresponding current which is referenced to a floating ground potential.  This current is then coupled to the balanced line for transmission to the central terminal.  The interface circuitry includes a DC to AC converter which converts the DC signal voltage to an AC signal.  This AC signal is capacitively coupled to an AC to DC converter which generates a corresponding DC voltage. The final stage is a transconductance circuit which produces an output current presenting the DC voltage level generated by the AC to DC converter.  In this manner, a ground refer-enced voltage is transformed to a floating ground reference current suitable for transmission down a balanced line.

Abstract: ABSTRACT OF THE INVENTION Two eccentric weights of a vibrator are mounted, respectively, on two coaxial shafts, one of which is a hollow shaft mounted on the other shaft.  The two shafts can be connected for rotation in unison, and can be separated for relative rotation to alter the angular rela-tionship between the weights.  Mechanism is provided to alter the angular relationship between the weights while both shafts continue to rotate.  The hollow shaft and the other shaft are connected, respectively, to one end of two beveled gear trains which can rotate as a unit about the axis of the shafts.  By changing the angular relationship between the gear at the other end of the gear trains, the angular relationship between the eccentric weights, and hence the stroke of the vibrator, can be changed.                           -1a-

Abstract: Abstract of the Disclosure A keyboard, actuatable with the aid of the tips of the fingers of at least one hand is disclosed.  The keyboard comprises a support frame, at least one row of keys, each of which can be moved out of an initial inopera-tive position by the tips of the index finger, middle finger, ring finger and little finger, respectively, without or with a hand rest for the ball of the thumb or wrist of the hand.  On this rest the hand can be continuously support-ed in a rest position during actuation of the keyboard.  The keys in one row constitute a guide key row in which the keys for each hand to be used for operating the keyboard are arranged on a curve, which corresponds to the natural disposition of the finger-tips when the fingers are, without being tensioned, in a slightly curved and spread, but relaxed posture.  Each key of the guide key row has a top face and comprises, at the end thereof opposite the top face, supporting means adapted for preventing downward depression of the key while permitting lateral shifting of the key toward at least one predetermined operational position, thereby permitting random vertical pressure to be exercised by a finger tip on the top face of a key of the guide key row without causing operational displacement of the latter key.

Abstract: A B S T R A C T      In a tool for cutting film or cardboard, it is known that a guillotine or industrial razor blade has been established as the method of cutting, and that mechanisms without power are marketed for manual steel rule cutting on top of the artwork. In this invention, the severing action of a 2000 r.p.m. motor driven circular razor, and the perfectly straight guidance of a fluorocarbon bearing carriage across a rigid transverse T-bar set at a maintained height above a table platform, makes heavy cuts without twisting or skewing and without clamping.  The design incorporates a slide that lifts and lowers to manipulate the inside bevelling of matboard.  Interchangeable with the razor arbor is a small diameter fine tooth saw arbor with an attachment for smooth cutting on thin paper.  The motor switch is a press on, hold, and release stop action entirely favourable to the concept of non-clamping.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a process for recovering uranyl cation from a wet process phosphoric acid feed solution comprising contacting the feed with a water-in-oil emulsion having an interior phase containing an aqueous solution of ferrous ions surrounded by a water immiscible, oily exterior phase.  The external phase contains a solution of di(2-ethylhexyl) phosphoric acid and tri-ctylphosphine oxide which transport the uranyl cations from the feed solution, through the exterior phase, to the interior phase of the emulsion wherein the uranyl ions are reduced to uranous ions and are thereby trapped in the emulsion.The emulsion is separated from the feed solution and the uranium is recovered. The extraction efficiency of this process ranges from about 50-1,000 compared to an efficiency of only about 1 to 7 conventional solvent processes.

Abstract: LOAD SENSING PROPORTIONER WITH PROPORTIONER DELAY            Abstract of the Disclosure A brake actuating pressure proportioning valve is positioned in a vehicle rear brake circuit.  The valve is sensitive to vehicle load to change the rear brake pressure point at which proportioning begins.  The valve is also sensitive to front brake circuit pressure.  If a significant decrease of front brake circuit pressure occurs, a delay piston is moved to follow the proportioner piston to a predetermined extent.  In this condition the delay piston keeps the proportioner from operating in a proportioning mode, permitting full rear brake circuit pressure to be delivered without proportioning action. The delay piston is spring loaded to permit a significant pres-sure delay in proportioning action before it is moved toward its original position with increasing rear brake circuit pressure.
