Filed: 1987-12-15
Granted: 1991-05-14
Abstract: ABSTRACT           MACHINE FOR MAKING PAPER BOOKLETS     In a machine for making paper booklets from a multiplicity of paper strips on bobbins that are converged into a continuously advancing strand a reciprocating cutting station defined by leading and trailing plates performs the operations of firstly clamping the strand while the station moves with the strand and secondly of cutting off booklet lengths of paper by means of a knife.  The booklets are ejected into a discharge chute by ejection means including an ejector bar terminating at a thrust plate. According to the invention the ejection means is separated from the cutting station and is fixedly located opposite to the chute.  Connection between the cutting station and the ejection means is established by a common rotating hexagonal shaft which is operably connected to clamping and cutting mechanisms of the station and which carries a pair of cams that actuate the ejector through a parallelogram linkage.  By this means the motion of the ejector can be gradual rather than abrupt, the machine is easier to set up, and the ejector thrust plate can span substantially the full width of chute so that the likelihood of cut booklets becoming misplaced is reduced.

Title: Automatic document feeder/separator for copiers
Inventor: LOONEY JOHN H
IPC: B65H1/18
Filed: 1988-03-16
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSED EMBODIMENT In a sheet feeding system for a copier, for the sequential separation and feeding of individual sheets from a stack of sheets by an impact type sheet feeder, there is provided a plural mode stack repositioning system for automatically repositioning the top sheet of the stack of sheets into an optimum feeding position relative to the impact sheet feeder, which optimum feeding position is closely adjacent to, but slightly spaced below, a maximum limit position of the top of the stack. This stack repositioning system further provides a retard repositioning mode in which the stack of sheets is automatically lowered into a retard position after each sheet feed has been initiated, which retard position is substantially below the optimum feeding position, in response to a sheet feeding sensor detecting a sheet being successfully fed from the stack by the impact sheet feeder and acquired by a take-away feeding system. Fixed position frictional sheet retard members are positioned to frictionally engage the next underlying sheet of the stack in this retard position to resist double sheet feeding. These retard members are not in the sheet feeding path in the optimum or initial sheet feeding position of the stack. There are also provided arrangements for arcuately deflecting the sheets being fed out to and by the take-away feeding system to provide increased normal force against the retard members in the retard position of the stack.

Abstract: ABSTRACT           An insulation and corrosion protection system for a pipe includes a pair of elongated and cross sectionally semi-cylindrical  segments  of  insulating  material,   and associated method of manufacture and  installation.   Each section of the insulating segments is made by wrapping a mandrel  with  an  inner  sleeve  material,   applying  an elastomeric inner jacket, a layer of insulating material and outer jacket.  A hinge is installed beneath the outer jacket for pivotally connecting the two semi-cylindrical portions of the  structure.   The  insulating segment  is  completely encapsulated within an elastomeric jacket material to seal the insulating member.  Before the insulating segment is in-stalled around a pipe an elastomeric sealing material is applied to exposed edges of mating surfaces of the semi-cy-lindrical portions of the insulation segments.   Then the semi-cylindrical  portions  are  positioned  around  a  pipe enclosing it.  Bands are secured around the exterior of the insulation segment to secure its separate portions together for curing of the adhesive material.  When the material has cured, the bands are removed and any exposed portions of the seam are then covered with an elastomeric sealing material. Adjacent ends of successive insulating segments covering a pipe  system are  joined with  an  adhesive  and  sealed  to provide for continuous sealing of the pipe for isolation from the environment surround the pipe.
