Abstract: A signature aligning and trimming apparatus wherein a stream of overlapping signatures are conveyed past first and second alignment stations on a lower conveyor belt system. Immediately after the second alignment, and while the signatures are still carried by the lower conveyor belt system, the signatures are engaged by an upper conveyor belt system and are pressed firmly against the lower belts as they are moved over large diameter rollers. The edges of the signatures are trimmed by single cutting wheels positioned to engage the edges of the signatures as they move over the top of the large diameter rollers. A pair of anvil plates, which are positioned beneath the cutting wheels and are rotatable with the large diameter rollers, provide a supporting surface for the signature edges against which the cutting wheels act in trimming the signature edges.

Abstract: A mechanically-expandable instrument (bougie), especially useful for treating diseases in the urethra and the neck of the urinary bladder, comprises an adjustable-speed driving unit (20) and a probe (22) composed of two rods (64) and (66) pivotally connected together at one end thereof and attached to output sliders (54, 56) of the driving unit at their other ends. Each of the rods (64) and (66) has a semicircular cross section so that in an assembled state the probe has a complete circular cross section. Reciprocations of the sliders cause expansions and contractions of the probe, thereby to stretch urethral constrictions in the radial direction and to subject the urethra and its the surrounding tissue to massaging and vibrational actions which are extremely efficient for treating diseases of the urethra and the neck of the urinary bladder. Other embodiments of the rod employ cams, wedges, and threaded means for creating radial expansions and contractions of the probe.

Abstract: An under reaming pile bore excavating bucket by which an under reamed part of a pile bore is excavated and the excavated soil is moved into the bucket for easy removal of the soil. In use, the bucket is lowered to the bottom of an already excavated straight pile bore; side apertures of the bucket are opened; the slidable wing drill bits are rotated and moved downward and outward along guide rails to excavate an under reamed part. The excavated soil is taken into the bucket through the side apertures and openable bottom apertures. When the drill bits reach their lowermost position, the drill bits are rotated reversely to house the drill bits again into the bucket and lastly the side apertures are closed. The soil within the bucket is raised from the excavated pile bore. In particular, a drive shaft is spline engaged with an outer pipe fixed to the center of the bucket body for allowing the slidable bits to rotate and further move downward or outward.

Abstract: The folded items (9) arriving from a folding apparatus (1) are grasped on the leading folded spine (10) by forward grippers (12) on an opening cylinder (8). Then the overhang (11) of each item is grasped by rearward grippers (13). Because of centrifugal force and optionally by means of an electrostatic charging device (7), the lower part of the folded item (9), after being released from the conveyor belts (5, 6), is repelled. As a result, rods (14) secured on a chain system (15) can be introduced, during their upward movement that is at a tangent to the opening cylinder (8), it between the two halves of one printed item, after which the transporting of the folded items (9) to further chain systems (such as 17) can be effected. Subsequently, folded items (9) can be collected one on top of the other and/or accelerated or delayed in accordance with how the transfer location is embodied.
