Title: Ct quick change assembly and force transmitting spacer
Inventor: MCKEE JERE L
IPC: H01H71/12
Filed: 1990-10-05
Abstract: A molded case circuit breaker is provided with a quick change current transformer assembly.      The current transformer is used to sense overcurrent conditions and apply a signal to an electronic trip unit to trip the circuit breaker. The quick change assembly includes an insulated removable plate located adjacent an open cavity in the housing in which the current transformer is located. The current transformer is donut-type disposed about a load-side conductor located in a cavity in the housing rigidly fastened to the circuit breaker frame. In order to replace a current transformer, the insulated back-plate is removed. Next the load-side conductor is unfastened and removed from the circuit breaker housing.      The current transformer is then removed from the circuit breaker housing. In order to install a new current transformer, the steps are reversed. A force transmitting spacer is disposed adjacent a bight portion of a shunt, connected between a pivotally mounted contact arm and a load-side conductor.    The force transmitting spacer transmits magnetic repulsion forces generated between the load-side conductor and the depending leg of the shunt adjacent the load-side conductor to the other depending leg of the shunt. By disposing the force transmitting spacer into the bight portion of the shunt the compression action required between the depending legs of the shunt is eliminated or reduced, thus reducing the blow open time significantly.

Title: Method and apparatus for checking film-cutting positions
Inventor: FLECKENSTEIN ALLEN E
IPC: G03D15/04
Filed: 1990-12-13
Abstract: A method and apparatus for determining whether a predetermined cut position lies within an unexposed portion of a roll of film is provided. A first density sensor 20 senses film density of a roll of film (10) and produces film density data. The film density data is stored in a first data storage device (50). A second data storage device (52) reads and stores a film density data value indicative of the lowest value of the film density stored in the first data storage device (50) and outputs this as base density data. A second density sensor (22) senses the film density at a predetermined cut position and produces cut position density data. A counter (66) counts pulses produced by a film drive and, when a predetermined number of pulses has been counted, indicating the arrival of the film at the predetermined cut position, the counter (66) produces a control signal that causes a comparator (26) to compare the base density data to the cut position density data. The comparator (26) produces a cutter control signal that causes a film cutter to cut the film (10) at the predetermined cut position only when the value of the cut position density data indicates that the film density at the cut position is within a predetermined range of the base density. In a typical installation, the film is comprised of several rolls of film spliced together. The invention includes a first splice detector (54) that detects a splice at a first time and a second splice detector (56) that detects the splice at a second subsequent time to identify each roll of film. The base density information is then keyed to a particular roll of film.
