摘要:
A tray packing-shrink wrapping machine for packaging articles along a conveyor is disclosed. The machine is operable in a dual lane mode and a single lane mode. In both modes a collation section receives articles from an infeed section and arranges the articles into rows and columns to create batches of articles. In dual lane mode a lane divider structure separates each batch into smaller microbatches. Separate trays and sheets of heat shrinkable film are simultaneously formed around the microbatches. An in-line stacker is selectively operable in single lane or dual lane modes to stack a packed tray on top of the preceding packed tray. The machine is quickly converted to single lane mode by removing the lane divider structure and center trayforming structures, removing the center stacker elements and retracting knives in the blank feeding and film wrapping devices. A method for converting a dual lane machine to a single lane machine is also disclosed.

A circuit breaker including a housing, separable contacts, a cradle rotatably mounted within the housing, an alarm switch mounted within the housing, and an interface lever disposed between the cradle and the alarm switch. The cradle is adapted to rotate about a first axis in a first direction when the circuit breaker moves to a tripped position in which the separable contacts are separated from one another. The alarm switch includes an actuation lever movable in an actuation direction, wherein movement of the actuation lever in the actuation direction causes the alarm switch to activate an alarm device electrically connected thereto. When the cradle rotates in the first direction, the cradle exerts a first force against the interface lever that causes the interface lever to exert a second force against the actuation lever that causes the actuation lever to move in the actuation direction.

A locking assembly is for the trip bar of a circuit breaker. A pivotal trip lever is coupled to the trip bar, in order to move therewith. The locking assembly includes: a locking mechanism, such as a commercially available key lock, with a pivotal element; a mounting plate, which receives the key lock and secures it to the circuit breaker; an extension member coupled to the pivotal element; and a flexible linkage interconnecting the pivotal trip lever and the extension member. The key lock has locked and unlocked positions corresponding to the trip bar of the circuit breaker being locked and unlocked, respectively. The flexible linkage is interchangeable or universally employable with a variety of commercially available locks, in order to lock the trip component of a wide variety of electrical switching apparatus.
