Abstract: A goniometric feedback device and an associated method for monitoring the relative angular position of two human body portions hinged at a common joint utilize a brace mechanism, transducer circuits, an array of selection light-emitting diodes (LEDs), an array of movement response LEDs, indicia associating with each LED array with a series of angular values, preselection circuits and sensing circuits. The brace mechanism includes two brace sections securable to the two body portions, and the transducer circuits provide an output electrical signal which varies in strength in response to a change in the relative angular position between the two brace sections so that the output signal strength corresponds to the relative angular position between the two brace sections.

Abstract: Two independent modules, disposed on a mobile handling platform, each comprise an endless chain with a pulling finger and a pushing finger. The operations of the chains are symmetrical with respect to the load drive axis. In operation, the pulling fingers engage a handle on the front of a load container and drive it until the pulling fingers reach a portion where their movement is lateral to the drive axis, temporarily stopping the container movement until the pushing fingers engage a handle on the back of the load container, serving to clamp the container during movement of the platform. Releasing the container can take place on the same side as that of loading by reverse rotation of the chains or from the opposite side by continuing the movement of the chains in the same direction, in accordance with an equivalent procedure.

The apparatus further includes a support (172) mounted on the shuttle and capable of supporting the strip when the engaging pin is engaging the moving strip, and structure capable of adjusting the support (172) towards and away from the portion of the measuring means mounted on the shuttle to establish a predetermined spaced apart measuring distance.

Abstract: An improved assay procedure for quantitatively detecting LDH.sub.k isozyme in human serum is provided which utilizes previously known electrophoretic gel separation procedures combined with an improved staining method wherein the staining solution has a constant temperature of about 37.degree. C. and a pH of about 8.0, and is contacted with the gel matrix for at least 3 hours in the absence of oxygen and light. This improved assay procedure may be used as an adjunct to other procedures for diagnosing the presence of primary cancer, as a post-operative indicator of metastatic cancer and in monitoring the success of cancer therapy.
