Abstract: A connector and diaphragm assembly can be interchangeably used in either of two types of vacuum-actuated automobile control systems. The connector which is seated in the closed end of a bell-shaped diaphragm is, in turn, connected to one of two types of linking elements that operate the control system. Deflating the diaphragm moves the connector thereby moving a linking element into one of two positions. The connector has a recessed neck portion and a head with a threaded hole therein. In a first automobile control mechanism, the recessed neck receives a forked linking element. In a second automobile control mechanism, the threaded opening of the connector receives a threaded rod which serves as the linking element. The same connector can be interchangeably employed with either type of linking element.

Abstract: A cleaning device for cauterizing knives presterilized for single surgical use and including a supporting frame adapted to be attached to a towel or drape used in surgery and held by an atraumatic clip also used in surgery, the frame containing a pair of abrasive strips having mutually engaging surfaces provided with diverging entrance ends, between which a cauterizing knife may be inserted to scrape cauterized flesh therefrom. In one embodiment, the supporting frame containing the abrasive strips also receives compressible plastic pads which applies a yieldable force pressing the abrasive surfaces into mutual contact, and also function to wipe loosely clinging material and also function as storage pads into which used blades may be thrust for later use or discard. In another embodiment, magnets urge the abrasive surfaces into mutual yieldable engagement. A further embodiment is arranged to clean cauterizing forceps as well as knives.
