  • Patent number: 4252139
    Abstract: A method and apparatus for automatically mixing a solution having a specified concentration is disclosed. The apparatus comprises: a storage tank, means for automatically introducing water into the tank, means for slowly introducing salt into the tank, and means for terminating the introduction of salt into the tank when the specific gravity of the tank reaches a specified value. Means are provided for preventing withdrawal of solution during the mixing cycle.

  • Patent number: 4176295
    Abstract: A high peak power microwave generator is disclosed in which a plurality of transmission lines are connected to an output wave guide at predetermined intervals along the direction of propagation. Each transmission line is periodically charged, and this electromagnetic energy is released into the wave guide upon the actuation of a light activated silicon switch (LASS) diode connected to the transmission line. The LASS diodes are actuated simultaneously by a laser beam which traverses equal optical paths to each switch. The coincident switching of the transmission lines enables the power in each line to be additive in the wave guide, and much higher output pulses can be obtained. Further, the high speed switching capabilities afforded by the LASS diodes means that the resulting high power can be obtained at a much higher frequency.

  • Patent number: 4086375
    Abstract: A monometallic batch process for forming beam leads of a preferred metal such as aluminum or gold. The process is applied to a wafer of finished microelectronic devices already having metal contact pads of the same preferred metal. Where aluminum is the desired metal, high deposition rates are used to minimize aluminum oxide contamination. High yield is achieved by forming the beam leads to have an elevated cantilevered configuration, by deep scribing of the wafer and, when desired, by providing an energy absorbing cushion to reduce the effect of collisions between chip edges and beam leads.

  • Patent number: 3989575
    Abstract: A split labeling apparatus and method for cutting and transferring pairs of individual labels from a double label web in preparation for separate, simultaneous application to product surfaces. The double label web is provided in roll form, is advanced through divider means for splitting the web into like longitudinal strips, and on to a cut-off means where a pair of individual labels are simultaneously removed, one from each strip. The cut-off means includes a cutting blade which prevents the strips from twisting. Each pair of cut labels is transferred from the cutting location by a pair of label separators which spread the labels apart during transfer. A second, simultaneously operating, anti-twist cutting blade is included to remove any periodically occurring scrap section from the web.

  • Patent number: 3954542
    Abstract: A labeling machine, system, and method capable of accommodating offset printed label tapes or other label tapes having discontinuities between the individual labels of a repeat print pattern, with feeding and severing such in controlled fashion utilizing a printed indicia code and a two stage feeding and cutting cycle, while uniquely securing and advancing articles or containers to be labeled with novel equipment, both in a manner to allow extremely accurate and dependable label application and subsequent label verification on the article as well as label position checking, and with discharge means positively governing discharge of the labeled articles according to acceptability or non-acceptability.
