Patent number: 6795320Abstract: A technique for supplying power and data signals to panel-mounted components includes distribution of power and data conductors in a trunk wireway and further distribution to component locations via drop cable assemblies disposed in drop wireways. The drop cable assemblies and trunk cable assemblies may include identical cable. The cables have a plurality of parallel conductors in an insulated jacket. Connectors are mounted on the drop cable assemblies for receiving plug-in component cable assemblies routed to individual components mounted within component panels or bays. The components are thus electrically coupled in parallel with one another and may receive both power and data signals via the drop and trunk cable assemblies coupled to a network. Individual components may be independent installed and removed for servicing with interrupting service to upstream or downstream components in the system.Type: GrantFiled: November 22, 2002Date of Patent: September 21, 2004Assignee: Rockwell Automation Technologies, Inc.Inventors: Chester Malkowski, Jr., G.

Patent number: 4785288Abstract: A modular smoke detector is adapted for mounting in an electrical equipment cabinet. The smoke detector module is of a standard size and configuration, thereby facilitating mounting anywhere in the cabinet. A mounting location near the bottom of the equipment cabinet is preferred to better detect the heavier than air combustion products of smoldering or burning insulation. The modular smoke detector includes a commercial ionization type detector and a fan. The fan induces air from the interior of the equipment cabinet into the module. The fan is positioned such that it does not discharge directly onto the ionization detector to prevent excessive speed of the air through the ionization detector.Type: GrantFiled: July 31, 1987Date of Patent: November 15, 1988Assignee: Allen-Bradley Company, Inc.Inventors: G.

Patent number: 4207602Abstract: A three phase motor is constructed with each of the three phase windings thereof split in half so that the motor may be selectively connected for energization from either a relatively high or relatively low source. Motor protectors are provided in the form of a three pole automatic resetting overload relay means and two thermostatic switches. The heaters for the individual poles of the overload relay means are connected in series with a half section of the individual phase windings and do not have to be changed when either high or low voltage energization is selected for the motor. The thermostatic switches are embedded in two of the other three winding sections but electrically insulated from the motor winding. The control contact means of the overload relay means and the thermostatic switches are connected in series with the energizing coil of the electromagnet for the contact through which the motor is connected to its energizing source.Type: GrantFiled: October 30, 1978Date of Patent: June 10, 1980Assignee: Gould Inc.Inventors: Frank W.

Patent number: 4144513Abstract: A multipole circuit breaker is constructed with a single rod pivotally mounting all of the movable contact arms to a common one piece molded insulating carrier. Individual torsion springs engage each of the contact arms to provide contact pressure when the circuit breaker is closed. The construction of the contact arms and carrier are such that under severe overcurrent conditions electrodynamic blowoff forces acting on the contact arms may bring about contact separation that is substantially as great as the contact separation that takes place when the circuit breaker is opened normally by its contact operating mechanism. An individual anti-rebound pin for each pole engages the contact arm of the associated pole to prevent rebound reclosing after electrodynamic opening. A camming means on the carrier releases the anti-rebound latches to permit manual closing of the contacts.Type: GrantFiled: August 18, 1977Date of Patent: March 13, 1979Assignee: Gould Inc.Inventors: Howard R.
