Abstract: A portable print head module dedicated to one type of printing, for example rotary screen printing, for functionally replacing one print head, dedicated to another type of printing, for example flexographic printing, in a rotary printing press having a number of spaced apart print head stations for transferring multiple images along the length of a continuous web substrate. The rotary print head module is installed by partially retrofitting one of the print head stations. The module can be moved to functionally replace any of the print heads in the rotary printing press. A non-rotating impression bar can be used to back the continuous web instead of a rotatable impression cylinder. A cushion of air is formed on the backing face of the impression bar on which the continuous web can ride.

Abstract: A machine for folding and shaping a partition for a case which carries a plurality of articles and for inserting the partition between articles in the case. The machine includes a hopper for holding a plurality of the partitions. Each of the partitions has slot means substantially centrally thereof. Vacuum cups can grip one of the partitions and move in a direction to free the partition from the hopper. A flight conveyor includes flight means for engaging of the partition at the slot means. The flight conveyor advances the partition to a folding station where the partition is folded centrally thereof. The flight conveyor further advances the folded partition to a forming and insertion station. A case having articles therein stops at a loading station below the forming and insertion station.

Abstract: The following specification describes a fusible switch assembly having a thermoplastic base supporting a plurality of pivotal knife blades. A one piece thermoplastic arc suppressor housing common to a plurality of phases is also described together with arc suppressor plates snap fit in the housing and a common one piece thermoplastic rotor for moving the blades. The rotor is retained by engagement with the knife blades and walls of the base.

Abstract: The following specification describes an integrally formed fuse puller assembled for limited movement to a fusible switch base in encircling relationship to a fuse mounted on the base for disengaging the fuse from a fuse clip.

Abstract: The following specification describes a pullout fuse holder having a cover and a base with asymmetrically arranged stop walls permitting the cover carrying fuses and terminals to be assembled in one orientation to the base for interconnecting line and load terminals and to be assembled to the base in another orientation to store the fuses without interconnecting the line and load terminals.

Abstract: The following specification describes a circuit breaker enclosure having a cover, which is latched closed by spring biased latch handles. The handles and cover move in response to gas pressure for relieving the pressure generated on tripping of the circuit breaker. The latch handles are arranged to point outwardly of the enclosure, when open, to provide a clear visual indication of their being open. The circuit breaker handle and enclosure handle are directly engaged with a common pivot pin for synchronous movement to enable the enclosure handle to indicate the trip condition of the breaker. When the cover is open, the handles are interlocked against movement to an ON position by a biased pivotable interlock plate. The cover in turn is latched closed through the interlock plate and a breaker handle plate, when the circuit breaker enclosure handles are in the ON position. A pair of spaced edge projections on the enclosure wall engage the cover sealing gasket to avoid a permanent compression set in the gasket.
