摘要： An automatic loading mechanism for use in the manufacture of thin, metallic circuit board panels. The invention includes a lower drum unit which accepts the metallic panels from a conveyor system. The lower drum unit is rotatably mounted within a frame assembly, and includes a plurality of clamps which can automatically receive several metallic panels of varying size. The lower unit includes automatic clamp control means, and has the capability of rotating the panels from a horizontal to a vertical position or vice-versa. The lower drum unit guidingly feeds the metallic panels, through a spline assembly, to an upper unit. The uppper unit includes a plurality of clamps, in diametrically placed pairs, which delicately handle only the peripheral edge of the metallic panels while feeding them automatically into a rack assembly.

摘要： A bipolar power supply capable of selectably supplying either a positive or a negative voltage at an output terminal. The power supply comprises a first operational amplifier, a second operational amplifier, a first transistor electrically connected to a positive voltage source and a second transistor electrically connected to a negative voltage source. The first transistor is electrically connected to the first operational amplifier and the second transistor is electrically connected to the second operational amplifier so that the first and second amplifiers control the operation of the first and second transistors respectively. The inputs of the first and second operational amplifiers are electrically connected in a manner that prevents them from simultaneously providing large positive voltages at their outputs.

摘要： A batch test or burn-in board system has a driver/receiver board having a plurality of driver/receiver circuits that are used for burning in individual circuits on a second board in a desired environment. The driver/receiver board sends timed pulses to each of the circuits on the second board. Calibration values for insuring appropriate timing of the pulses from the driver/receiver circuits are stored in a memory that is mounted directly on the driver/receiver board. The calibration values are retrieved from memory under computer control for operating the driver/receiver board for the batch test or burn-in sequence.

摘要： A valve construction, particularly a three-way, two-position valve which may be used by itself to control fluid flow, or which may be used as a pilot valve to control operation of a larger valve. The valve comprises a cartridge which may be installed within or removed from the bore of a valve body as a unit. The cartridge unit comprises a valve plunger, a plurality of similar glands, and a plurality of similar separators carried by the plunger, with static seals on the glands and dynamic seals between separators, and a spring for urging the plunger to a predetermined position. The cartridge unit is held within a body bore by means of a cartridge nut which is threaded into one end of the bore. The nut has one end bearing against a separator at one end of the cartridge unit and presses a separator at the other end of the unit against a fixed abutment in the bore, so that axial movement of the plunger does not cause separation of the glands and separators.
