Title: Surge control method and apparatus
Inventor: STEEBER DORIAN F
IPC: B65G47/57
Filed: 1990-08-10
Abstract: ABSTRACT OF THE DISCLOSURE    Surge control apparatus and corresponding method are particularly adapted for the safe handling of highly crushable and/or tearable products, such as paper-based box type aseptic packages.  A flow of products along a conveyor exiting an accumulator is held until previously released products have progressed a predetermined distance down the conveyor towards a subsequent workstation, such as a packer.  If a product queue occurs within the accumulator, the upstream flow of packages is halted, and the queued products are shifted relatively slightly downstream against a movable locator mechanism.  Such stopping and shifting isolates from production line pressures the packages to be removed from the conveyor.  Through such isolation, adjacent package shear points are prevented as a vertically-oriented conveyor mechanism is used for removal and subsequent return of packages relative the conveyor.  A movable transfer plate is manipulated in a position just lateral of the conveyor to facilitate alternate removal and return of packages relative thereto without tearing of package paper coverings. Maintenance of a predetermined downstream product gap facilitates placement of the locator mechanism.  After a removal sequence, several non-removed packages are forced upstream into a pre-shifted position for being re-clamped by an outfeed brake, so that subsequent downstream shifting steps may take place for proper isolation of further queued-up products before their removal.

Filed: 1991-03-19
Abstract: CORD-TYPE TIRE TRACTION DEVICE  ABSTRACT OF THE DISCLOSURE A tire traction device for vehicle tires includes a pair of rope-like side cord members for circumferential placement on the sidewalls of a tire.  A series of metal or synthetic rope cross cords interconnect the side cords and extend across the tire tread.  The cross cords are connected to the side cords at knotted connections. Enlargements at the ends of each cross cord outside the knotted connections prevent the cross cords from disconnecting from the side cords.  Coil spring rollers supported on the cross cords provide additional traction. Tubular spacers on the cross cords inside the knotted connections center the rollers on the cross cords.  A series of male connector knots along one end of each side cord selectively interengage a female loop connector knot at the opposite end to join the opposite ends together about tires of different circumferences.  The male connector knots extend between at least one pair of cross cords to enable radical adjustment of the device to length by cutting the side cords to length from the one end and removing cross cords as necessary from adjacent the one end.  In a light-weight, low cost version of the device, the cross cords are formed of conventional sash chain, eliminating the need for rollers, spacers and enlargements at the cross cord ends.
