Abstract: ROLL ON TYPE FLUID APPLICATOR WITH           SEALING MEANS     ABSTRACT OF THE DISCLOSURE     A roll-on type fluid applicator which has a ball type fitment or collar with a roll-on ball therein and a cap or closure therefor.  The ball type fitment is formed of a plastic material and has a rim adjacent the mouth thereof with an inwardly extending rim lip to engage the ball and forming a sealing connection therewith.  The cap is detachably secured to the container to cover the fitment.  The cap has a top with a plurality of downwardly extending pressure applying flexible fingers formed inte-grally with the top and extending downwardly for engagement with the ball. The cap also has a flexible sealing mem-ber formed integrally with the cap and extending inwardly of the interior of the cap.  The flexible sealing member is positioned in a plane lower than the plane of the down-wardly extending flexible fingers.  The cap, when tightened with respect to the container, will cause the pressure applying fingers to bear against the normally exposed portion of the ball to urge the ball inwardly or down-wardly in the direction of the fitment so that it esta-blishes a seal tight contact with a lower sealing ring in the lower portion of the fitment to block the discharge of the fluid from the container.  The flexible sealing member of the fitment engages the rim of the fitment to form a seal therewith.  The cap sealing member and the lower sealing ring of the fitment will prevent the major portion of the ball, namely the portion extending above the lower sealing ring of the fitment, from drying up when in non-use position.  The flexibility of the pressure applying fingers and the flexibility of the cap sealing member will com-pensate for the dimensional variability and fit between the fitment and the ball and the cap and fitment and yet provide effective sealing between the parts.

Abstract: ABSTRACT         A scanning microprobe in which a gun generates a beam of charged particles controlled to scan the surface of a specimen in a predetermined and defined manner.  In order to permit blanking of the particle beam by removing the trace of the beam from the surface of the specimen at a particular time for a predetermined period, high-speed, high-stability switching circuitry is utilized.  A vertical MOSFET switching transistor is connected between one plate and ground of the system.          Also connected between this plate and a deflection voltage source is R current-limiting resistor having a ratio of approximately 15 9 000-1 with respect to the switch MOSFET in its turned-on condition.  A second switch is provided to momentarily shunt the current-limiting resistor when the MOSFET switch is turned off.          This produces an initial rapid rise time of voltage on the deflection plate causing the beam to immediately move off the specimen surface.  Turning off of the MOSFET switch and momentarily turning on the shunting switch is accomplished by an external beam blanking signal.

Abstract: PUSH-PULL PULSE AMPLIFIER HAVING IMPROVED         TURN-ON AND TURN-OFF TIMES                 ABSTRACT OF THE DISCLOSURE     A pulse amplifier formed of first and second field effect transistors, each exhibiting an inherent input capacitance at its gate electrode, the field effect transistors being con-nected in push-pull relation whereby their drain or source electrodes are connected to a common output terminal.  First and second resistive circuits are connected in a pulse supply circuit to supply pulse signals to the respective gate electrodes of the field effect transistors.  Each of the resistive circuits exhibits a higher resistance when a pulse is supplied therethrough to turn the respective field effect transistor ON and a lower resistance when the pulse is terminated to turn the respective field effect transistor OFF.   The higher resistance of the resistive circuit cooperates with the inherent input capacitance of the respective field effect transistor to provide a higher discharge time constant to turn that field effect transistor ON and the lower resistance cooperates with the inherent input capacitance of the field effect transistor to provide a lower charge time constant to turn that field effect transistor OFF, whereby the field effect transistors are not ON concurrently.          In a preferred embodiment, the field effect transistors are complementary field effect transistors so that a positive-going pulse turns one of those field effect transistors OFF while turning the other ON, and a negative-going pulse turns the one field effect transistor ON while turning the other OFF.                             -i-

Abstract: IMPROVED CARTRIDGE LOADER            Abstract of the Disclosure An improved cartridge loader of the type having a gen-erally star shaped latch rotatably carried within a casing, the casing defining a plurality of cartridge bores positioned circum-ferentially around the latch.  Upon rotation of the latch, the latch and each cartridge bore cooperate by alternately capturing and releasing a cartridge's flange within that bore for loading and unloading cartridges therefrom.  A first novel feature of this improved loader is a semi-automatic rotation device for the star shaped latch, which device induces rotation of the latch from the capturing position to the releasing position in response to an ex-ternal force directed axially against the loader's knob when the casing is restrained against rotational motion, e.g., when the cartridges in the casing are disposed in an unload attitude rela-tive to a revolver cylinder, and which will not induce rotation of the latch unless the casing is so restrained for preventing acciden-tal release of stored cartridges if the loader is dropped or other-wise subjected to an undesirable external force on the loader's knob.  The semi-automatic rotation device is also manually operable to set the latch from the releasing position to the capturing po-sition, and to return the latch from the capturing position to the releasing position, simply by manually rotating the loader's knob.          In a preferred form of the semi-automatic rotation device, the knob is connected to a centerpost through a spring loaded cam structure, the star shaped latch being immobily fixed to the centerpost.  A second novel feature of this improved cartridge Loader incorporates a resilient but stationary bore closure member that, preferably,defines a circular contact locus radially outward of the cartridge bores' circular center axes locus.  The latch and bore closure member cooperate to minimize jiggling of cartridges stored within the casings' bores for reducing undesirable noise, to allow nominal unopposed movement of the cartridges' nose ends relative to the casing for aiding initial cartridge insertion into a revolver's cylinder when loading the cylinder, and, when the casing is dropped, to cushion any shock transmitted to the car-tridges' flanges and to protect the cartridges' firing pins.  In a preferred form, the cover member is defined by a one-piece multi fingered washer type structure coaxially located, and fixed in position, relative to the casing, the resilient fingers overlying the casing's bores at the cartridge flange end thereof.
