Abstract: The present invention provides method and apparatus for determining lead integrity of IC devices characterized by an inspection arrangement which comprises optical elements for back lighting the leads disposed on either side of a trackway for the travel of the IC device thereon. The optical elements are arranged in such a fashion as to simultaneously produce a sharp backlit silhouette image of the leads protruding from either or both sides of the IC device. In accordance with the invention, means are provided for continuously and automatically feeding IC devices through an inspection station in the apparatus where an illumination source through the optical elements directs an intense light beam so that a sharp silhouette or backlit outline of the leads on both sides of the IC device is simultaneously obtained. A single camera is disposed to face the opposing direction of the illumination and optics to receive the silhouette or backlit outline of the IC device leads, as well as the top surface of the device.

Abstract: A drop dispenser having a sleeve carrying a closure and resilient dosage receiving fitting. The sleeve is treadably mounted an a fluid containing container having a nipple thereon. The closure on the sleeve has a configuration corresponding to the configuration of the nipple for sealing the nipple in the closed position. The fitting is filled with fluid from the container by turning the sleeve in a direction away from the closed position on the nipple to an open position to thereby establish fluid communication between the container and fitting. The fluid is dispensed from the fitting by squeezing the fitting after the closure has been returned to the closed position on the nipple, thereby preventing fluid from flowing from the resilient fitting back into the container. Cooperating stop members are provided between the sleeve and bottle neck to limit the movement of the sleeve relative to the bottle neck.

Abstract: A terminal connector assembly comprising a terminal housing, having at least one terminal contact which can be inserted into the terminal housing for connection to a conductor, and with a plug contact for the plug-in connection of a contact pin assigned to each terminal contact and in electrical contact therewith, means for pre-inserting and holding the said contact pin as a separate contact pin in the plug contact, whereby at least one end of the contact pin projects out of the terminal housing.

Abstract: A rolling bearing having an inner ring, an outer ring, and a plurality of rolling elements between the rings. A seal is mounted in the annular space between the rings comprising a flat disk (6), mounted to one of the bearing rings made of a material with good electrical conductivity. An annular member (9), attached to the other bearing ring whereby the seal functions as a current bridge to carry away electrical current according between the two bearing rings.

Abstract: A limited pour neck finish bottle wherein a plurality of radially inwardly extending flexible fingers are integral with the peripheral edge portion of the open end of the neck of a bottle and extend across the open end of the neck to restrict or interfere with the flow of liquid from the bottle if an attempt is made to pour the liquid from the bottle rather than employing an exact dose dispensing device. The bottle is made by molding a plurality of axially extending flexible fingers on the peripheral edge portion at the open end of the neck simultaneously with the molding of the bottle, and then bending the fingers downwardly to the radially inwardly extending position.

Abstract: A terminal connector comprising a housing (10), a contact element (30), in the housing, said contact element having at least one clamped connection for connecting a conductor (50), and at least one connecting contact formed on the contact element, said contact element (30) being a one-piece member and having edges shaped to form springs (32, 33a, 33b, 36a, and 36b) for at least one clamped connection and at least one connecting contact, and means mounting the contact element (30) in a positive, form-locking manner in the housing (10).

Abstract: A locking mechanism for machine parts having aligned grooves comprising a spring ring engageable in the grooves of the machine parts in a locking position and wherein the material of the spring ring is weakened continuously in the circumferential direction at the juncture between the machine parts to define a predetermined breaking point.

Abstract: Apparatus for molding plastic caps having inclined tabs integral with the lower edge of the cap skirt and radially inwardly extending ribs integral with the inner surface of the cap skirt. The tabs and ribs are formed by a plurality of blades having recesses on the ends thereof corresponding to the configurations of the tabs and ribs. The blades are mounted on a core and extend into a female mold having a cup-shaped cavity. A linear drive member is mounted on a fixed plate assembly and connected to a ratchet sleeve rotatably mounted on a movable plate assembly. The end of the ratchet sleeve is provided with circumferentially spaced teeth engaging the lower peripheral edge of the cap skirt. Movement of the movable plate assembly relative to the fixed plate assembly causes the ratchet sleeve to rotate to move the molded tabs and ribs away from the recesses of the blades so that the finished cap can be stripped from the apparatus.

Abstract: Acoustic shock waves for medical uses are generated by an electrical discharge between two electrodes, which are mounted in a liquid medium. A catalyst is added to the liquid medium in the area of the electrodes; this catalyst partially or completely catalytically converts the gas which forms upon application of the voltage to the electrodes back into its original state or partially or completely prevents the formation of the gas.

Abstract: A surveillance system which can store and replay information which is not generated contemporaneously. In some point-of-sale systems, the behavioral events occur before the transaction data is generated. The present system asynchronously records the video signals corresponding to the behavioral events and the transaction data. Upon playback, the transaction data is matched up with the behavioral event being replayed from the video tape.

Abstract: A break away overcap (1) is used for maintaining a closure (6) in sealing engagement with the open end of a vial (2). The overcap (1) is molded from a fracturable plastic and is provided with a pair of spaced, parallel score lines or V-grooves (5) extending across the top wall (3) of the overcap (1) and downwardly of the cap skirt (4) to the lower edge thereof on each side of the cap. Thumb and finger engaging portions (4a) are provided at the lower edge of the skirt (4) adjacent the terminal ends of the score lines (5) so that by pushing inwardly on the thumb and finger engaging portions, (4a) the overcap (1) breaks into three pieces to thereby expose the closure (6) for insertion of a syringe needle therethrough into the vial for removal of the vial contents therefrom.

Abstract: Method for measuring the output torque of an asynchronous motor having a stator and a rotor comprising the steps of measuring the rotational frequency of the stator field of the motor, the rotational speed of the rotor, calculating a measurement value for the slip speed from the difference between the rotational speed of the rotor and rotational frequency of the stator field, and calculating a measurement value for the output torque form the slip speed and statistical performance characteristic values for the output torque intrinsic to the motor.
