Abstract: ABSTRACT OF THE DISCLOSURE            A flavor composite comprises a mixture of sorbitol, mannitol, saccharin, and a flavor material contained therein.  Pref-erably, the saccharin is present in an amount of 3% by weight of the mannitol.  The presence of mannitol and saccharin is theorized to lower the congealing temperature of sorbitol, so that volatile flavors may be incorporated therein with minimal flavor loss.            The present flavor composite may be prepared in the form of sugar-free candies, or may be reduced to particles or beads 3 having particle sizes appropriate-for incorporation into com-estible products such as chewing gums;            A method of preparing the flavor composites is also disclosed which utilizes seed particles containing sorbitol, added to the mixture after the flavor to assist in the commencement of harden-ing.

Abstract: IMPROVED PRESSURE SWING ADSORPTION           PROCESS AND SYSTEM                    Abstract of the Disclosure Bed utilization and product recovery are enhanced in pressure swing absorption operations, especially for high pressure applications, by terminating cocurrent depressurization at a relatively high intermediate pressure level. Additional void space gas is released from each main adsorption bed by partial countercurrent depressurization prior to conventional countercurrent blowdown.  Such additional gas is passed to a satellite bed adapted for simultaneous release of gas from its discharge end, thereby cocurrently depressurizing said satellite bed from said intermediate pressure level, with the thus-released gas being passed to the discharge end of another satellite bed or beds and/or another main bed or beds for pressure equalization and/or purging purposes.  The satellite bed is one of a satellite group of adsorption beds containing a lesser number and smaller beds than in said main bed system, the satellite beds not being operated above said intermediate pressure level.

Abstract: IMPROVED TOOL AND METHOD FOR GRAVEL PACKING A WELL            Abstract A gravel packing tool includes a differential piston sleeve normally covering an auxiliary return port through the wash pipe located above an annular seal of a sand screen liner.  The seal engages the wash pipe sealing against pressure communication between upper and lower sand screen sections in the liner. A shear pin connecting between the sleeve and the wash pipe holds the sleeve in its port closing position until the pressure differential between the inside and outside of the wash pipe causes the sleeve to shift into a second position breaking the pin and exposing the port to establish an auxiliary path for liquid to return through the wash pipe.  A spring acting between the sleeve and the wash pipe urges the sleeve back into its closing position when the pressures inside and outside the wash pipe begin to equalize.

Abstract: CLOCK CIRCUIT     ABSTRACT     A clock generator circuit (10) receives an input signal PPC0 and generates a delayed clock output signal PC0.  The circut (10) is set to an initial condition by a precharge signal PC0R prior to a transition of the input signal PPC0.  A time delay signal is produced at a node (26) by operation of transistors (18, 28).  The transition of the input signal PPC0 produces a bootstrapped voltage at a capacitor (68).  The delay signal activates a transistor (80) to couple the bootstrapped voltage to the gate terminal of an output transistor (88).  The gate terminal of the output transistor (88) is driven directly from a low voltage state to a boosted high voltage state.  This causes the output signal PC0 to be driven from an initial low voltage state to the power supply voltage Vcc without intervening steps. The output transistors (88, 90) of circuit (10) are never activated at the same time, thereby preventing any current spike from being propagated through the circuit (10).

Abstract: METHOD AND APPARATUS FOR MONITORING UNBURNED PARTICULATE ACCUMULATION IN      THE EXHAUST DUCT OF A COMBUSTION SYSTEM     Abstract The unburned particulate accumulation within the exhaust for a combustion system, such as the liner of a flue for a stove, is monitored by a circuit which receives a temperature indicating signal from a thermo couple mounted within the flue.  The circuit includes comparators which process the temperature signal to determine whether the temperature is within in any of three ranges.  When the temperature is within a normal burning range, the elapsed time that the tem-perature remains within such range is stored as a first count whose magnitude is proportional to the accumula-tion of particulates.  When the first count exceeds a prescribed level, a warning device is activated. When the temperature reaches a higher cleaning range that is sufficient to burn the accumulated particulates, the elapsed time that the temperature remains within such range is stored in a second counter.  The first counter is reset when the value of the second counter reaches a prescribed value.

As the tool is loaded by a feed rate increase, the motor speed will increase to that point empirically determine to provide a good finish for the material and cutting implement size selected.  If the load decreases, the motor speed will correspondingly decrease to that speed which will provide a good finish for the material and cutting implement size selected with out overheating of the material.  A limit would be set to indicate to an oper-ator when he is at the upper limit of the speed and feed rate range and turn off the tool after a short period of time to prevent destructive overheating.

Abstract: ABSTRACT   In the box annealing of steel sheet, the tendency for adjacent wraps of the sheet to pressure weld (stick) is decreased or eliminated by passing the sheet, prior to annealing, through a rinse containing from 1,500 to 10,000 ppm of the magnesium or calcium salts of soluble carboxylic acids, preferably formates.  Further benefits are realized if the sheet is electro-cleaned with a silicate or phosphate containing cleaning solution, and thereafter rinsed in the formate solution whereby the latter acts to fix the concentration of silicates or phosphates remaining on the surface of the sheet.
