Title: Self-locking divider plate for an electrical box
Inventor: FABIAN MARK E
IPC: H05K7/00
Filed: 1993-06-02
Abstract: A self-locking divider plate made of flat sheet metal is provided in an electrical box to form separate compartments. The electrical box has several upper and lower front ledges which form aligned slots which in turn, cooperate to receive the divider plate. The side edges of the divider plate has a biased sheared tab which locks the plate in place between the slots upon installation of the plate into the box. These sheared tabs extend outwardly from one of the planar surfaces of the plate.  When the plate is inserted into two aligned front slots, the tabs are pushed inwardly toward the planar surface of the plate, and spring back to their normal position when the plate is in its proper position in the box. The tabs engage an inside surface of the ledges when the plate is moved outwardly from the box to prevent its accidental removal. Tangs on the back edge of the plate fit into slots in the back wall of the box, and tangs on a front edge of the plate adjacent to the sheared tabs engage the walls of the slots to position and secure the divider plate within the box.

Title: Resource-oriented printer system and method of operation
Inventor: DENNIS STEPHEN V
IPC: G06T11/00
Filed: 1993-07-09
Abstract: RESOURCE-ORIENTED PRINTER SYSTEM AND METHOD OF OPERATION     Abstract of the Disclosure A host computer and printer and method of operation is disclosed wherein the data file describing a document is examined by a resource assembler which determines which resources are required from the host computer to print the document. The resource assembler translates the document into a set of render primitives for each band or page of the document and creates an dependency list interrelating the required resources with each band or page. The resource assembler places the required resources and set of primitives into a host resource store and communicates the dependencies to other portions of the system. A resource loader uses the list to determine the most efficient manner for loading and releasing resources from a printer resource store. A resource scheduler controls the actual timing of resource and primitives transfer and determines when all required resources for a band or page are present within the printer resource store. The resource scheduler generates an execute signal which causes a resource executor to convert the primitives to a bit-map data file. The resource assembler may convert the primitives to a bit-map data file if the resource executor cannot convert the primitives in real-time while the print engine is printing the band or page. The resource assembler also converts the primitives if it is more efficient than the resource executor for converting a particular band or page. If bidirectional communication is available between the printer and host computer, the printer manages its own memory and determines the most efficient printing sequence. Enhanced error recovery is also possible with bidirectional communication.

Title: Fail-safe condition sensing circuit
Inventor: SIGAFUS PAUL E
IPC: F23N5/08
Filed: 1992-10-22
Abstract: A circuit for detecting whether the level of an electrical signal having a preselected polarity is above a preselected value, is powered by DC of the opposite polarity. This prevents current leakage within the detector (20) circuit from simulating the level of the electrical signal. Such a circuit is particularly suited for detecting the current level provided by a flame sensor in a combustion control system. The preferred embodiment has a capacitor (55) which is charged by the circuit and then discharged by the electrical signal. The time required to discharge the capacitor (55) to a preselected level indicates the level of the electrical signal. A second embodiment uses a comparator (42) in a feedback loop which allows sensing the level of a voltage outside of the voltage range defined by the comparator's (42) power supply.
