Abstract: ABSORPTIVE STRUCTURE HAVING IMPROVED SURFACE DRYNESS AND IMPROVED RESISTANCE           TO REWETTING IN-USE                  Lawrence H. Sanford A B S T R A C T      Absorptive devices, such as disposable diapers, presenting a dry surface feel to the user.  In a partic-ularly preferred embodiment of the present invention, a substantially planar, moisture absorbent layer is disposed between a soft and bulky, wearer contacting, moisture-pervious topsheet and a moisture-resistant back-ing sheet to form a disposable diaper.  The topsheet prefer-ably comprises an integral structure containing a multiplicity of depressed areas which intimately contact the uppermost surface of a substantially planar, moisture absorbent layer, while the non-depressed areas of the topsheet contact the wearer's skin in-use.  Due to the wet resilience and increased overall caliper of the topsheet, the non-depressed areas, which are of substantially the same density as the depressed areas, tend to isolate the wearer's skin from moisture contained within the moisture absorbent layer, thereby providing improved surface dryness and improved resistance to rewetting when the structure is temporarily subjected to pressure resulting from the wearer's body movements.

Abstract: Abstract of the Disclosure This specification discloses a method for electro-static separation of crude potassium salts into its components, the separation process being of the type carried out at relative humidity of 2 - 30% in the presence of a conditioning agent.  The method involves reduced requirements as to the amount of the conditioning agent.  The process is characterized in that the ground potassium salt, comminuted to the required grain size, is brought into contact with a gaseous conditioning agent, so that the conditioning agent is held to the surfaces of the salt crystals by adsorption. The amount of the conditioning agents is adjusted by controlling the temperature of the gasifying (or vaporizing) air and/or by controlling the volume of heated air and/or gas volume, used as a carrier; whereupon the separation in an electrical field into two or more fractions and middlings is effected, the fractions being subsequently removed and the middlings brought back to the feed.

Abstract: PUSH-BUTTON COMBINATION LOCK FOR VEHICLES          ABSTRACT         A push-button keyboard is located on the dashboard of a truck for unlocking a rear access door to rear cargo space in the truck.  Selected ones of the keys are sequen-tially operated in accord with a given combination generating a signal which throws a lock bolt as by means of a solenoid. A first timer prevents operation of the lock unless the combination keys are operated within a first given time interval.  A second timer automatically releases the solenoid operated lock bolt after a second given interval of time has elapsed to relock the access door in the event it has not been opened.  The signal to the solenoid operated bolt itself is frequency coded to inhibit introduction of un-authorized signals in an unauthorized attempt to operate the lock.

Abstract: ABSTRACT OF THE DISCLOSURE                 A pivotal disc shut-off valve is disclosed wherein a disc is pressed against a peripheral seat within a valve body to halt the flow of fluid material in a flow line.  The disc is operated by a system of linkage arranged so as to allow the disc to be linearly moved in relation to the seat as a separate and distinct motion from pivotation of the disc.  In closing the valve, a provision is made by which the disc is rocked as it contacts the seat to insure full closure.          All motions of the disc are positively directed, with no reliance on the force of gravity, thus allowing the valve to be used in all positions.

Abstract: A B S T R A C T           A plastic caul for embossing wood panels which preferably comprises a laminate of sheets of epoxy prepreg -- e.g. fiberglass webs impregnated with partially cured epoxy resin -- has been dis-covered.  The caul may optionally include a metal core sheet.  The embossing face of the caul contains a relief design, usually trans-ferred from a natural wood grain pattern.          To form the caul, a mold is first prepared.  The mold may comprise a textured wood panel, the design surface of which has been sealed and then coated with a release agent.  This treat-ment prevents the panel and future caul from sticking together. Sheets of the epoxy prepreg are then layered onto the treated sur-face of the panel and compressed under heat and pressure conditions against it.  In this manner, a relief of the textured design of the wood panel is transferred to the caul as it is further cured.          The plastic caul may then be separated from the wood panel and baked until fully cured.  The configuration of the wood panel assumed in relief by the plastic caul is thus permanently maintained and the caul may be used for embossing smooth wood panels with the textured design of the panel used in making the mold.

Abstract: ABSTRACT OF THE DISCLOSURE          A clamp has a first curved portion with one end connected to a second curved portion which overlaps or surrounds a segment of the first curved portion including the free end thereof.  The free end of the second curved portion is connected to an extension, which has an elongated slot adjacent its end and an inclined lower surface adjacent its end.  A base extends from one of the first and second curved portions in substantially the same direction as the extension and has an inclined upper surface at its end for cooperation with the inclined lower surface of the extension.  The base has an opening extending therethrough to receive a screw, which passes through the slot in the extension prior to passing through the opening in the base.  As the screw is advanced into a support structure engaging the lower surface of the base, the lower inclined surface of the extension moves relative to the upper inclined surface of the base to cause each of the first and second curved portions to have a smaller curvature whereby the first curved portion, which is the smaller of the two curved portions, is clamped against an article to be held.  The outer surface of the first curved portion and the inner surface of the second curved portion have cooperating means to prevent lateral pull out.  The inner surface of the first curved portion has article engaging elements.

Abstract: ABSTRACT OF DISCLOSURE         A circuit for preventing overcharging of the local battery in a carrier subscriber station terminal includes a Darlington compound having a first resistor connected between the ungrounded side of the battery (which is also connected to a battery charging circuit) and the junction of the first transistor emitter electrode with the second transistor base electrode, the transistor collector electrodes being connected to ground.  The series combination of a Zener diode and a voltage divider consisting of second and third resistors is also connected across the battery, with the junction of the second and third resistors being connected to the first transistor base electrode.  The diode has a Zener voltage such that when the battery voltage exceeds a prescribed voltage, the diode breaks  down and the voltages across the first and third resistors are then such that both transistors are turned on to bypass a major portion of the charging current away from the local battery to prevent it being overcharged.  In an alternate embodiment, the transistors are connected as a bootstrap compound.
