Abstract: An external tissue expansion device applies constant continuous low grade force to skin to obtain additional tension free skin and subcutaneous tissue prior to a surgical procedure. The device consists of two suture plates each being laminated structure of steel and an adhesive attached foam cushion. On the each end of one suture plate is a housing that contains a constant force spring placed over a post. The ends of the constant force spring protrude from the housing and there is a hook attached to the end of the constant force spring. On each end of the other suture plate there is a housing, with a opening that can accept the hook of the opposite suture plate. These suture plates are constructed so that they can be manually shaped to conform to the topography of the body part to be corrected and are attached to skin near the defect to be corrected prior to a surgical procedure.

Abstract: A device applies continuous tension to skin adjacent an ulcerative area, to expand and approximate this skin until it covers the ulcerative area. The new device includes a frame which defines a path in which sliders move under the force of a constant tension spring. Each slider includes a hook-like element that engages and pulls the skin until the skin on opposite sides of the ulcerative area comes together. This element is curved, thus defining a plane which is oriented perpendicular to the path of the slider.

Abstract: A test shoe adapted to engage a discrete area on a telephone connector block normally mounted upon a telephone main frame for the purpose of interfacing with a plurality of individual subscriber circuits appearing on the block through protector modules. The shoe is configured to afford adequate clearance with respect to the projecting handles on the modules, the shoe being mounted in position by the engagement of a resiliently urged laterally moving latch released by push button means accessible from an outer surface of the shoe.

Abstract: An automatic system for the surveillance of the incremental speeds of production equipment including a pair of rotary driven gears rotatable about a common axis and in face to face relation. The rotary driven members are independently driven by activating stepping, cocking means including a pulse energized solenoid. An arm laterally movable in response to said pulse extends from a position adjacent the solenoid. Adjacent the forward end of the arm there is a coil spring frictionally maintained in engagement around a shaft and having an extension adapted to be engaged by said arm. A leaf spring is disposed rearwardly of the extension of said coil spring. When the arm moves in response to the pulse it contacts and rotates the coil spring and also moves the leaf spring into taut or cocked position. When the arm is released by the interruption of the pulse the leaf spring is also released as well as the coil spring.
