Abstract: An adjustable strike incorporates a bracket defining a slide, a striker plate including a latch-engaging section and an integral slider slidably positioned in the slide and an adjusting screw recessed into the bracket underneath the slide, said screw having a head accessible at an edge of the bracket and a thread threadedly engaging the slider. Projections are provided at the opposite sides of the slide which overhang the edge margins of the slider to slidably retain the slider in the slide. The bracket and screw are simple molded plastic parts and the striker plate is a simple formed metal part. All three parts can be assembled quickly without any tools by placing the screw in the bracket recess and engaging an edge of the striker plate slider under the projections at one side of the slide and pressing the slider down into the slide whereupon its opposite side edge becomes engaged under the projections at the opposite side of the slide.

Abstract: A disposable medical electrode includes a compliant annular support layer having an adhesive surface, a compliant discoid gel pad having a diameter less than the inner diameter of the support layer, an electrical terminal and a holder for maintaining the support layer, gel pad and terminal in relative juxtaposition. The holder includes a pair of mating sections which can be clamped together on opposite sides of the support layer and terminal to retain those components against relative motion. Also, one section includes a central passage through it for snugly receiving the gel pad so that one surface of the gel pad is in intimate contact with the terminal and the opposite surface of the gel pad is exposed at the outer end of said passage and lies more or less in the same plane as the adhesive surface of the support layer.
