Abstract: A device is provided for securing a wiping element to the superstructure of a wiper blade. Each of two backing strips (13) of the wiping element (2a) is provided, at its exterior longitudinal edge, with a flattened area (13a, 13b) which laterally projects from said exterior longitudinal edge. One of the claws (11a) of the superstructure of the wiper blade surrounds the flattened areas (13a, 13b) and thus prevents any longitudinal displacement of the backing strips (13) with respect to said claw (11a). The longitudinal displacement of the wiping element (2a) with respect to the backing strips (13) is prevented by similar flattened areas (13a', 13b') which compress the wiping element (2a) in the zone of the claw (11a).

Abstract: A baling machine according to the invention has a frame having walls defining an elongated compaction chamber having a front end provided with a transversely open intake to which a stream of crop is fed substantially continuously. At least one compacting member is periodically displaced in the chamber between a front position forward of the intake and a back position rearward of the intake by an appropriate drive so as to rearwardly compact crop in the chamber. A plurality of pushers are each displaceable between an advanced position projecting into the chamber and only partially blocking the intake and a retracted position substantially out of the chamber by a linkage that advances the pushers into their advanced position only when the member is rearward of the intake and of the pushers. Thus advance of the pushers into the advanced position immediately after movement of the compacting member rearward past the pushers parts the stream of crop between the pushers and compacting member.

Abstract: A concealable wiper apparatus for a vehicle has a wiper assembly disposed in such a manner that the wiper assembly can be accommodated in an accommodating chamber provided inside the body of the vehicle and in the vicinity of a window glass. The wiper assembly is vertically moved between an accommodated position at which it is accommodated in the accommodating chamber and a raised position at which the wiper assembly wipes the window glass. In addition, a wiper arm which supports a wiper blade that wipes the window glass is adapted to be capable of expansion and contraction. Accordingly, when the wiper is not used, the wiper apparatus is accommodated in the accommodating chamber, so that it is possible to minimize the air resistance to the vehicle and reduce the size of the accommodating chamber.

Abstract: A baling machine for forming large cylindrical bales of hay has a variable volume baling chamber defined by moving belts with a crop inlet on the underside of the machine. When a bale has been completed it is wrapped with surface wrapping material stored in a holder on the back of the baler. The wrapping material is advanced by feed rolls through a cutting mechanism below the holder, and is thus guided by a plate extending along the underside of a run of the belts to the baling chamber. In order to avoid wasting wrap, a cutter is triggered by a peg carried by a metering wheel movable between an adjustable "home" position against an abutment or stop to a trigger position in which it engages and lifts a release lever to release the cutter, and this distance is a measure of the length of wrap material required for the completed bale. In respective embodiments, the metering wheel is in the form of a friction wheel, a worm wheel and a ratchet wheel with all wheels being selectively driven by one of the feed rolls.
