    摘要： The invention concerns an optocoupler. The optocoupler includes a substrate made of optically opaque electrically insulating material metallized to provide conductive traces on a top surface thereof which are electrically linked to metal pads on a bottom surface. A cadmium sulfoselenide photoresistor having an active surface is placed over the substrate with the active surface facing the substrate where the photoresistor has two electrodes. Metal leads connect each of the two electrodes of the photoresistor to two metallized traces on the substrate. A light emitting diode (LED) chip is mounted on the substrate facing the active surface of the photoresistor. The LED chip has a top and bottom electrode, where the bottom electrode is electrically attached to a third metallized trace and the top electrode is wire bonded to a fourth metallized trace. A cover made of optically opaque material is fixed to the substrate so as to enclose the photoresistor and the LED chip in a light tight enclosure. In an alternative embodiment of the invention, the photoresistor and the LED chip can lie side by side and be in optical communication with each other through a reflective coating on the inside of the cover.

    摘要： A device is disclosed for separating, orienting and positioning axes including at least one operational flat. The device includes a static chute equipped with a wide bottom opening closed by a drawer which is moved with a back and forth motion from a withdrawn position in which it unveils a narrow opening which is large enough to enable the fall of a single axis onto rolling blades which are extended by descending ramps bringing each axis onto two bearing-sliding blades. The bearing sliding blades cooperate with two push plates, as well as a trap borne by the drawer, to produce the roll of the axis in the desired direction, followed by the slide of that axis without rotation to a selected position.

    摘要： A metal body is inspected for defects by relatively longitudinally displacing it and a plurality of pairs of coils connected in respective bridge circuits that are excited with alternating current. The coils are also excited with alternating current so that eddy-current variations caused by defects in the body become impedance variations of the coils which in turn become imbalance signals in the respective bridges. The imbalance signals are demodulated to form respective imbalance voltages which are periodically sampled and the levels of the sampled demodulated voltages are stored. The sampled demodulated voltages of each bridge are averaged to produce respective base lines which are compared with the respective stored levels of each sampled voltage for generation of respective error signals corresponding to the differences. These error signals are compared with a first relatively low threshold corresponding to the smallest defect to be detected and with a second relatively high threshold. When one of the error signals exceeds only the first threshold it indicates a small defect at the respective location on the body and when one of the error signals exceeds the second threshold it indicates a large defect. A longitudinal succession of at least abutting zones is established on the body and the error signals for each zone are summed. Each of these sums is compared with a predetermined third threshold and when one of the sums exceeds the third threshold it indicates a long defect in the respective zone.

    摘要： A device for separation, orientation, and positioning of parts essentially flat in their general shape, characterized by the fact that the parts are supplied in flat position upon a storage rail and that the device includes, in combination, a tilter which can be activated by a piston between an initial, raised position and a second, tilted position, with the tilter including a support forming a continuation of the storage rail when the tilter is in raised position so as to receive the first of parts from the reserve, with stops arresting the rest of the parts, and with the support further including retaining members (9) for preventing the part from being dislodged, while stop pads stop the first part remaining on the rail during tilting of the tilter.
