A locking mechanism with an electronic solenoid opening and a mechanical reset is disclosed. The locking mechanism comprises a solenoid which requires low power levels to activate and has a short activation period, resulting in reduced energy requirements and extended battery life. After being placed in the unlocked position, the locking mechanism remains unlocked until a mechanical reset is activated by a person turning a handle of the mechanism.
Machine For Handling Circuit Package Storage Tubes
Invention Design Engineering Associates, Inc. - Torrance CA
International Classification:
B65B 6900
US Classification:
414411
Abstract:
A fully automated machine is capable of selecting a single "A"-frame storage tube for dual in-line integrated circuit packages from a number of such tubes in a bulk storage bin and then rotating that tube about its longitudinal axis so that the dual in-line packages can be fed into or out of the storage tube in either the live bug (leads down) or dead bug (leads up) positions. The machine will also remove and then replace the stop pin at one end of the storage tube.
Method And Edge Finding Apparatus For Use On A Machine Tool
A method and apparatus for finding an edge of a workpiece prior to machining the workpiece by a machine tool. The apparatus includes a collar that is mountable to be secured to the head of a machine tool. The collar has four flat surfaces spaced in quadrature on the outside surface thereof and an adjustable reference member extending outwardly therefrom for initial calibration. The apparatus also includes an edge finding assembly that is releasably clamped to the collar at the reference members for edge finding and carrying a dependent contact probe coupled to a dial indicator for indicating the movements of the contact probe, the collar and edge finding assembly being adapted to be fixed in a preselected vertical plane when mounted to the collar secured to the head of a machine tool for finding the true zero X & Y reference edges of a workpiece to be machined.

International Classification:
H05K 330
US Classification:
29740
Abstract:
A head assembly for a burn-in board loader and unloader comprises a mounting block having a generally vertical track. A main body is mounted on the mounting block and afforded vertical movement along the track. The main body has a vertical bore through which a vertically movable plunger extends. The main body also comprises at least three vertical mounting wire holes spaced-apart around the bore. A floating crown having a vertical bore through which the plunger extends is mounted on the upper end of the main body by mounting wires which are fixedly attached at their upper ends to the crown and extend downwardly into the mounting wire holes. The mounting wires are fixedly attached at their lower ends to the main body at the lower ends of the mounting wire holes. The crown is preferably mounted to provide a gap between the crown and main body of about 0. 005 inch.
An electro-mechanical coin totalizer for newspaper vending machines and the like includes a coin chute having an arcuate shoulder, a wake-up arm, and optical sensors for measuring a chord length on coins inserted in the totalizer. A coin inserted in the coin chute travels along the arcuate shoulder, whereby coin bounce is minimized and the accuracy of coin chord measurements is enhanced. The wake-up arm biases coins against the arcuate shoulder and reduces coin bounce in direct proportion to the size of the coin.
Method And Apparatus For Automatically Extracting Integrated Circuit Packages From Electrical Sockets
A method and apparatus for automatically extracting a series of integrated circuit packages from their sockets without bending the leads thereof. A plurality of extraction fingers are caused to be moved between a socket mounting an integrated circuit package and the package to an extent to permit the package to be extracted from its socket in a direction substantially perpendicular to the plane of the socket. The extracted packages are controlled after their release to cause them to travel through a checking station to determine the condition of their leads. The integrated circuit packages that have not been damaged will continue to travel down an incline and be accumulated. The damaged integrated circuit package will be held at the checking station and then ejected automatically from the apparatus during the operation of an extraction cycle.
A sensing mechanism for commercially available printing machines wherein paper is automatically fed into the machine sheet by sheet. The sensing mechanism is adapted to be mounted to the machine for permitting it to sense the arrival of a stack of paper at a preselected location as the paper feed table is automatically elevated. When the preselected location is sensed, the table elevation is arrested to prevent the prior art paper "overfeeding" problems.
