Abstract: A glow-plug ignitor for diesel engines and the like, comprising a tubular body having external screw threads and an adjoining hexagonal formation by which a tool such as a wrench can be applied to the body to screw it into the threaded cavity of a cylinder. Next to the hexagonal formation is a spade lug connector for bringing current to the plug, the connector being so arranged as to permit the application of either a socket-type wrench or else a box-end wrench. The inner end of the body has an elongate projecting pin on which there is a tightly wound resistance coil that becomes incandescent when excited with the proper electric current. The valleys of the coil show higher temperatures, for a given heating current, due to the radiation and reception of radiated heat involving the opposed surfaces; therefore, starts at lower engine temperatures are improved.

Abstract: An adapter for coupling a windshield wiper blade holder with a wiper arm of the type having a hooked end is provided as a unitary molded body of a resilient plastic material forming similarly shaped side panels held spaced apart and joined together by a front wall and a cross shaft which are so disposed relative to portions of the panels that the arm hook can be engaged onto the shaft when the body is turned away from a posture in which it can be coupled with the blade holder, and will be captured operably in the adapter when the body is turned back to that posture.

Abstract: A windshield wiper blade unit for use with a blade holder, or pressure distributing wiper structure, having a detachable blade-carrying yoke portion comprises a backing member consisting of an extruded elastically resilient strip having a longitudinally hollow central portion slotted along its bottom to receive slidably the head and neck portions of an elastic wiping element and having along its opposite sides laterally open claw-receiving channels defined by flanges which have ridge forming deformations that protrude into the channels to limit movement of the blade unit relative to the claws of the blade holder. Depressed portions of the upper flanges coact with the ridges formed by the deformations. The extruded strip serves also to keep the wiping element in place by virtue of the top wall of its central portion having segments thereof stuck down into the hollow to abut the ends of the wiping element.
