  • Patent number: 4052922
    Abstract: A cable cutting member is adapted to be driven forward in a cable holder to cut a cable therein. For driving the cutting member, an explosive charge is detonated by a spring pressed firing pin slidably mounted in the holder behind the charge. A firing pin retractor slidably mounted in the cable holder behind the firing pin is detachably connected with the pin for retracting it a predetermined distance to compress the firing pin spring, the connection being such that when the pin has been retracted a given distance, it will be released automatically. A considerable distance behind the retractor there is a cylinder having a front end and a closed rear end and containing a piston spaced from both ends and mechanically connected with the firing pin retractor. The cylinder has an opening for water between its front end and the piston so that an increase in water pressure in the cylinder will move the piston rearwardly therein to pull the retractor far enough to release the firing pin.

  • Patent number: 4050555
    Abstract: An extruded plastic housing of indefinite length contains an electrical conductor bar in a slot extending lengthwise of the housing. The bar is retained in the slot by a pair of ribs integral with the side walls of the slot and extending lengthwise thereof and projecting toward each other. The width of the bar is greater than the space between the ribs, but the housing is so formed that in assembling it and the bar the distance between the ribs can be increased temporarily by pressure of the bar against them to permit it to be moved rearwardly past the ribs, whereby the bar can be inserted from the front or outer side of the slot, thus permitting the use of a single conductor bar regardless of the number of housing units that may be disposed end to end to form the housing.

  • Patent number: 4046634
    Abstract: A simple, rapid anion-exchange column chromatographic technique is used to determine the presence of fractions of proteins and enzymes in human serum by separating the fractions on the basis of their net electrical charges. Samples of serum of unaltered ionic strength, layered on mini columns of an ion exchange agent previously equilibrated to a low ionic strength similar to blood serum with a buffer solution, are eluted stepwise with an appropriate buffer solution having different ionic strengths at each step. Elution of the samples is without previous dialysis or other ionization treatment. Column effluents are assayed for protein content or enzyme activity by conventional means, e.g., spectrophotometric analysis. Evaluation of sera from patients utilizing these methods reveals protein fractions or isoenzyme patterns which identify specific diseases associated with the protein or isoenzyme pattern.
