A utility cylindrical lock set having a series of pin tumbler bores accommodating a plurality of pin stacks and biasing springs is provided with an improved cap. The external surface of a cylindrical lock body includes a cap-receiving groove crossing the open upper ends of the pin tumbler bores. The sides of the groove are undercut to form overlying flanges. An elongated cap having a central portion to overlie the pin tumbler bores and edge portions offset downward from the central portion is re...

A capping machine turret has a number of circumferentially spaced screw-cap applying spindles with a cap engaging chuck at the lower end of each spindle. Each screw cap applying spindle of the capping machine is rotated by means which frictionally applies an accurately predetermined torque to the spindle and therefore to the cap engaging chuck at the lower end of the spindle. This is accomplished by providing a pair of pinions which are rotatably mounted on each spindle and are continuously rota...

This disclosure relates to a capping machine for applying caps to containers, such as jars. The capping machine is provided with a simple automatic cap feed wherein the caps are gravity fed through an orienting chute which directs the caps towards a cap locating station with which there is aligned a capping chuck. The caps are primarily advanced by gravity and as they approach the cap locating station, fluid jets, preferably steam, are directed against the caps to advance them to their positions...

A capping apparatus including a cap chute which is particularly suitable for applying a press-on twist-off cap having a tamper-evident ring to a container such as a glass jar. The cap chute has a guide extension and profiled components which control the cap so that it is maintained in the correct orientation within both the capping apparatus and during collection by the container.

An improved flash memory device, which comprises core stacks and periphery stacks which are protected with an oxide layer, a protective layer and an insulating layer. A high energy dopant implant is used to pass the dopant through the insulating layer, the protective layer, and oxide layer into the substrate to create source and drain regions, without using a self aligned etch. The flash memory device has an intermetallic dielectric layer placed over the core stacks and the periphery stacks. A t...

The present invention relates to an apparatus for capping in succession containers transported on a conveyance device. The apparatus comprises a cap dispensing station for applying caps on the containers. The cap dispensing station includes a cap release passage, a gating unit and a movable cap ejector. The gating unit includes a barrier, capable to acquire either one of first and second operative positions, and a barrier drive mechanism. In the first operative position, the barrier at least par...

An automated capping machine is provided which seals heat shrinkable film about the mouth of an open container. The machine has a pneumatically operated drive system which is actuated by container placement. On actuation, heat shrinkable film advances to a cutting and shrinking position and the container is raised to meet the film. Movement of the cup brings the film against a hot wire cutter and advances the film-cup combination to a heat shrink station. The heat shrink station is designed to p...

An electric capping machine for crimping the caps of containers, in which each cycle of operation takes place fully automatically, once initiated by the operator; in the course of each operation, a container-receiving member is automatically raised into engagement with a spring-loaded abutment roller of the crimping mechanism which, upon further upward movement, causes the crimping roller to be positively brought into engagement with the edge of the cap by the use of a quadrilateral linkage conn...

A machine for attaching threaded caps to containers continuously moving in a longitudinal path and having endless belts disposed at opposite sides of the caps with the cap engaging belt portions traveling in opposite directions to impart twisting motion to the cap. The belts are moved transversely of the path into and out of engagement with the caps at a uniformed but variable rate to impose two or more pulses of twisting movement to each cap. The times of engagement and disengagement of the bel...

A capping apparatus including a cap attachment assembly and a cap tightening turret to be used in conjunction with a container filling turret having a conveying apparatus for transferring the filled containers to the capping turret. The cap attachment assembly includes a housing for supporting a cap in the path of motion of the neck of the container and a pretightener assembly positioned to level the cap on the neck of the container as the cap is pulled from the housing and to impart an initial ...
