Abstract: A container device that dispenses paper from a roll, with a roll (B) in reserve. The device has two substantially parallel pins (4,4') for supporting and unwinding paper (10) from the rolls (A, B) with two openings (20) corresponding to the pins in the lower portion of the device contained within a housing. A sector (5) shaped as part of a circle is mounted to freely rotate about one of the pins. The sector (5) has a peripheral flange (5a) that is adapted to obstruct the corresponding opening (20). When the sector (5) is kept at a first, substantially vertical position, the opening (20) is obstructed. A spring (15) urges the sector (5) to rotate until reaching a second position at which point, the previously obstructed opening (20) is made accessible.

Abstract: A hand-held power-operated blade-actuating or other work member actuating device, especially useful as shears for processing comestible products such as fowl. A servo mechanism and linkage connected with a movable blade and a finger control causes controlled powered movement of the blade in coordination with the finger control. A fixed blade and a pivoted blade are insertable and removable as a unit from a hand-held frame in which the fixed blade is restrained against rotation relative to the frame. The blades and frame are constructed so the blades are insertable or removable only when closed. In a preferred embodiment the fixed blade is retained in part by two load bearing pins extending from the frame and located substantially diametrically opposite each other relative to the pivot axis of the movable blade.

Abstract: Apparatus for dividing laminated glass consists of a device for dividing laminated glass, and a glass cutting table 30 with a cutting bridge 33 which can move along a support and on which a cutting head 38 for scratching plates of glass can move. The device for dividing laminated glass is located on one of the edges of glass cutting table 30 which run parallel to cutting bridge 33. On cutting bridge 33 of glass cutting table 30 there is stop 40 for orienting the laminated glass in the device for dividing laminated glass. Thus the amount of space required is reduced. The device for dividing laminated glass can also be made narrower or can have only one movable support 5 if a support 2 affixed to the frame is made integral with the bearing surface of glass cutting table 30. The glass cutting table is not used to divide the laminated glass: only its cutting bridge is used, and only as an adjustable support for the stop 40.

Abstract: A portable saw table which comprises an elongated saw table and a saw track pivotally mounted therebetween for a rotation about an axis substantially perpendicular to a longitudinal axis of the table base. A saw slide mounted on the saw track and supports a portable saw. A support at each end of the saw table allows the portable saw table to be tilted relative to the supports about a second axis parallel to the axis of the table. A sector member is pivotally connected to the table base so that as the table base is tilted, the sector member is moved in a plane perpendicular to the axis of the saw table. The sector member provides stability and guides the table and saw track. Thus, the table base, saw track and sector member can be tilted relative to the supports while the saw track is allowed to pivot relative to the table base and the sector member. A locking device on the supports engages the sector member to lock the saw table in a tilted position.
