Title: Adjustable slotter wheel and sheet feeder retrofit apparatus for box blank making machines
IPC: B31B50/22
Filed: 1992-05-21
Abstract: Box blank-forming apparatus (60) is provided which includes a feeder assembly (62) and a scoring/slotting assembly (64) each provided with adjustment structure (62a, 64a) to facilitate makeready adjustment of the apparatus (60) between production runs. The feeder assembly (62) preferably includes a reciprocal pusher element (170) operable to successively engage sheets (30) to be formed into box blanks (36). The element (170) is supported by a pair of elongated, threaded, axially rotatable, fore and aft translatable positioning screws (146, 148), so that upon rotation of the screws (146, 148), a reference position of the pusher element (170) may be varied. Adjustment of the assembly (64) is accomplished by means of compensators (292, 294) which are respectively coupled to associated slotter wheel and scoring wheel shafts (288, 286). Operation of the slotter wheel shaft compensator (294) serves to adjust the circumferential positions of the fixed slotter knives (358), whereas operation of the scoring shaft compensator (292) varies the position of the adjustable knives (360) through the medium of transfer gears (384). Servo-sensors (438-442, 446-448 and 270) are used to continuously monitor the lateral and circumferential positions of the scoring/slotting stations (296-304) and a reference position of the pusher element (172), so that precise makeready adjustments can be accomplished. <IMAGE>

Title: Neighbor-assisted handoff in a cellular communications system
IPC: H04W36/08
Filed: 1992-03-10
Abstract: A handoff system where handoff requests are initiated not only by a home or serving base station, but also by neighboring base stations. As in conventional handoff, a serving base station may initiate a handoff request when the signal strength of one of its mobile stations falls below a predetermined threshold. In addition, neighboring base stations monitor the signal strength of neighboring mobile stations and request that a neighboring mobile station be handed off when that signal strength reaches a predetermined level. Thus, a handoff request may come from the serving base station because of a poor call connection or from a neighboring base station because of a possible strong call connection.

IPC: B65D50/04
Filed: 1994-06-29
Abstract: A screw cap contains, on its cylindrical outer wall, a grooving which continues into the outer annular region of the lid section. The grooving consists of lamella ribs each having a slightly inclined long side and a short side which lies in a plane lying around the longitudinal mid-axis of the container closure. An outer cap which can be fitted onto the screw cap has a lid section which is convex relative to the screw cap, is supported centrally on the lid section of the screw cap, and can be deformed elastically into an approximately flat alignment by applying axial force. During this process, projections moulded onto the inner side of the lid section of the outer cap engage in the grooving of the lid section of the screw cap so that a torque can be transmitted in the opening direction. In the opposite direction of rotation, the outer cap is connected by end faces of an annular shoulder to projections of the screw cap. The screw cap can be used as a single closure or in combination with the outer cap as a child-resistant pressure/rotary closure. <IMAGE>
