Granted: 1998-12-22
Abstract: A sheet inverting and stacking system in which a rotatable sheet stacking unit receives the lead edge area of an incoming sheet and then rotates and releases that lead edge area of the sheet at a lead edge registration position for stacking the sheet inverted in a set of stacked sheets at least partially on a stacking tray in a stacking area; with a movable sheet registration system providing plural sheet lead edge registration positions; a sheet set fastening system (stapler) for fastening the stacked sets; a first registration position for set fastening in which the sheet stacking area extends into the sheet set fastening system and a second registration position in which the sheet stacking is in front of the sheet fastening system, to provide two different initial sheet leading edge stacking positions and one final stacking position. The rotatable sheet stackingunit is interdigitating with the movable registration system to carry the sheet lead edge directly into the first or second registration positions and also into the sheet fastening system in the first registration position. The stapler is under and at least partially inside of the rotatable sheet stacking unit, and the rotatable sheet stacking unit slots carry the lead edge area of the incoming sheet directly up to the first registration position and into the stapler before releasing it. The sheet lead edge retaining slots have low force retaining spring members which lightly hold the lead edge of the sheet against one side of the slot.

Title: A device with host indication combination
Inventor: PETERSEN BRIAN
IPC: G06F13/12
Filed: 1993-09-17
Granted: 2001-01-02
Abstract: Combined indication signals of data block transfers are generated by a device which reduces the number of interrupts to a host processor (5). The reduction in the number of interrupts enhances host system performance during data block transfers. An embodiment of the device may be a network adapter (3a) comprising network interface logic (11) for transferring a data frame between a network (2) and a buffer memory (9) and host interface logic (11) for transferring a data frame between a buffer memory (9) and a host system (1). The network adapter (3a) further includes threshold logic (10) for generating an early receive indication signal when a portion of the data frame is received. Indication combination logic (l0a) delays the generation of a transfer complete interrupt to slightly before the expected occurrence of the early receive indication. The host processor (5) is able to service both the transfer complete indication and the early receive indication in a single interrupt service routine caused by the transfer complete indication.

Title: Takeaway/correction conveyor system for food product machine
Inventor: LINDEE SCOTT A
IPC: B65G15/10
Filed: 1995-07-27
Granted: 2000-02-22
Abstract: A stand-alone takeaway and correction conveyor system for a food loaf slicer or other food product machine that produces groups of food products that must be held to close tolerance as to weight or some other readily measurable characteristic includes two conveyors, one for reject groups and one for acceptable groups.  The two conveyors are mounted on one base, in spaced parallel relation to each other, with the reject conveyor above the accept conveyor.  Both conveyors are driven, at related speeds, from one drive; the drive is mounted in the base and is energized and controlled, as to speed, from the food product machine.  The conveyor for acceptable groups has a pivotal outboard section to allow for service of packaging equipment without moving the system.          Both conveyors have eccentric mounts to compensate for large elevation differences in packaging equipment.  A correction tray is used for correction of reject groups of food products.  Controls on the base enable an operator to stop the food product machine and the conveyors and to jog the reject conveyor.

Title: Conductive probe for heating contact lens mold assemblies during demolding
Inventor: WIDMAN MICHAEL F
IPC: B29C35/02
Filed: 1997-06-02
Granted: 2006-05-09
Abstract: Demolding apparatus for reliably and repeatedly mechanically separating contact lens mold assemblies without damaging the contact lens formed therebetween. The mold assembly includes a frontcurve mold having a central mold section with a surrounding flange, and a corresponding backcurve mold also having a central mold section with a surrounding flange, with a contact lens being molded therebetween.      The demolding apparatus includes a conductive heating probe which contacts the backcurve mold of the lens mold assembly to conductively heat the backcurve mold.      Heat is conducted by the backcurve mold to cause a temperature gradient between the backcurve mold and the lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the backcurve mold relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the molds, while leaving the lens in the frontcurve mold.      The conductive heating probe includes a convex heating surface which contacts and is the same general shape as a concave surface on the backcurve mold, and can also include a compliant heat conductor to conform to the concave surface on the backcurve mold. In one embodiment, the apparatus includes a conductive heating probe assembly having an n x m array of conductive heating probes which contact each backcurve mold of an n x m array of molds assemblies positioned in a support pallet.
