An intermediate drive is provided between a reciprocating element connected to the wiper arm and the driving rod of the drive to enlarge a path of the translatory movement of the driving rod.

Abstract: Apparatus for mixing or otherwise agitating fluid material comprises an elongated vessel (1) to contain the material, means (6, 7, 9, 10) to impose oscillatory motion upon the material in a lengthwise direction, and a plurality of stationary obstacles (19, 35) mounted on the inner wall (2) of the vessel and arranged in sequence lengthwise. The obstacles present sharp ridge-form tips (20, 37) each ridge pointing in a direction (30) at right angles to that of the oscillating motion. Each adjacent pair of obstacles and the length of vessel wall between them define a trough-shaped space (26) in which the oscillating motion repeatedly forms vortices and then ejects those vortices vigorously into the remainder of the fluid outside the trough, so promoting the agitation of that fluid. The invention applies particularly to cylindrical vessels in which the obstacles are ring-shaped (19) or are constituted by the successive turns of a helix (35).

Abstract: A compound windshield wiper having a blade assembly consisting of a main wiper blade and an adjacent and secondary reciprocating blade in slideable registry therewith. The secondary blade, slideable attached to the main blade by an interlocking bearing-in-slot assembly, is driven towards an extended position during the wiper's arcuate sweep along the windshield, thus allowing the secondary blade, called a traveler blade, to clean portions of the windshield that are normally uncleaned by the traditional windshield wiper blade system. The means for extending the secondary blade comprises a simple cable system that both extends and retracts the secondary blade. The cable may be driven by either a motor means that is synchronized with the wiper sweep, similar to or identical with modern vehicle wiper system motors or, by anchoring the terminus of the cable (the proximal end) to some point of the window frame or vehicle body.

Abstract: A vacuum cleaner main cleaning chassis has a pair of suction air channels leading from a principal suction area thereof. Suction force is provided in common in the air channels with a single suction motor. One of the suction air channels is adapted to receive an auxiliary cleaning hose which diverts the suction force in such air channel into the auxiliary hose. During such auxiliary cleaning, increased suction force may be created in the auxiliary hose by closing off air flow in the other suction air channel, which relieves part of the load on the common suction motor. Such relief results in increased rotational speed of the motor, which in turn correspondingly increases the suction air flow in the air channel associated with the auxiliary hose.

Abstract: A mechanical lock-in device for a front loader compaction assembly to prevent relative movement of the refuse container with respect to the stationary compactor head and support. The lock-in device includes a lock-in bracket fixed to the compactor head support, and a locking member movably mounted on the refuse container adjacent one of the horizontally extending side pockets which are engaged by lifting forks of a collection vehicle for dumping. The lower portion of the locking member engages the lock-in bracket to prevent relative movement of the refuse container while in use. When it is desired to dump the container, when the lifting fork of the collection vehicle is inserted into a container side pocket, it engages a portion of the locking member which extends transversely of the pocket, thereby effecting an upward movement of the locking member out of engagement with the lock-in bracket to permit the container to be moved from its position beneath the stationary head.
