Abstract: Abstract A wiper blade for motor vehicles has a wiping element (6) attached to a superstructure which includes a main bridge (1), one or more intermediate yokes (2) and one or more secondary yokes (3), with at least one of the components (1,2,3) of said superstructure replaced by at least one air deflecting device (14).  In a preferred form, at least one air deflecting device replaces at least one secondary yoke, with each air deflecting device (14) extending parallel to and at a certain distance from the wiping element (6) of the wiper blade.  The air de-flecting device or deflector (15) has attachment members (16,19,21) for securing the deflector to one of the com-ponents (2) of the superstructure of the wiper blade and has additional attachment members (17,4') for securing the deflector to the wiping element (6) of the wiper blade.  The deflector has at least one resilient blade (18) capable or exerting a pressure on the wiping element (6) of the wiper blade.  The invention results in a wiper blade having a ratio of the distance between the deflec-tor (15) and the wiping element (6) and the distance between the bottom edge (15') of the deflector (15) and the surface to be wiped (12), which ratio is substan-tially equal to ten.

Abstract: ABSTRACT     Movable bucket elevators for carrying bulk material are subject to loading forces caused by the feed motion (thrust motion) of the buckets and their chain guides.  In order to reduce the loadings to a large degree and thus to increase the useful life of the elevator, there is provided in the lower zone of the elevator path a stationary (fixed) cylindrical casing and a rotary cutting head encircling the casing.  The cutting head is provided with shovels adapted to cut the bulk material and bring it to the front of an opening in the casing where the material is scooped up by ascending buckets.  As a result, the buckets have virtually a scooping function only.

Abstract: DRILL BIT WITH FULL OFFSET CUTTER BODIES         Abstract of the Disclosure A rotary drag drill bit is seen wherein cutter bodies are rotatively connected to a main body structure at a fully offset position.  The fully offset position is defined by a rotational axis of each cutter body, a longitudinal axis of the drill bit and end support points or positions of the cutter bodies.  The rotational axes of the cutter bodies are perpendicular to the longitudinal axis of the drill bit.  The end supports of the cutter body are each equal distance from any point on the longitudinal axis of the drill bit.  The cutter bodies of essentially ellipsoidal configuration, being slightly thicker at a mid-portion thereof.  Cutting elements are connected to flutes projecting above an outer surface of each cutter body.  In a primary rotational direction of the drill string and drill bit, the rows abrade the bottom and side walls of a well bore as the cutter body attacks the earth formation as the drill bit is rotated.  The impingement of the cutting elements of the cutter body on the earth formation imparts a secondary rotation to the cutter bodies, which secondary rotation is induced by the primary rotation.  The secondary rotation allows the rows of cutting elements to engage the side wall of the bore and gauge the hole as well as abrading away material from the bottom of the well bore.  A roller bearing assembly is provided for the cutter body to permit the secondary rotation, while a thrust bearing assembly assists the primary abrasive action imparted by the primary rotational movement of the rotary drill bit.  A lubrication system is included in the main body structure of the drill bit wherein both the roller hearing assembly and thrust bearing assembly are lubricated.
