Abstract: This invention relates generally to fabrics, films, sheets and other supporting media that contain and transport fire retarding materials. These transport media deliver fire retarding and smoke suppressing constituents to the surface of fiber reinforced polymer (FRP) composite substrates during a manufacturing process. Upon exposure to open flame or radiant heat, the resultant manufactured product has much lower surface flammability and smoke development characteristics than would otherwise be achieved by the substrate material alone. By economizing the fire retardant constituents at the surface only, cost is reduced while also avoiding deleterious adulteration of the substrate material. When fire is prevented from penetrating the surface, combustion of the entire part is delayed or prevented. By embedding fire retardant within the surface using the native resin, no peeling or chipping occurs (as with paint), and the finish will be essentially as hard and durable as an untreated part.

Abstract: A surface coating includes fire retarding and smoke suppressing constituents dispersed throughout an essentially non-toxic, water-based adhesive binder. The coating comprises a mixture of chemical compounds where each constituent falls into one of six functional groups, being: 1) catalyst/initiator; 2) expandable graphite; 3) carbonific, or source of carbon which additionally forms water; 4) blowing agent (a source of non-flammable gases); 5) cement; and, 6) ceramic.

Abstract: A flame retarding and smoke suppressing additive powder that can be mixed with resins includes a carbonific material, a heat activated blowing agent, a heat activated halogen material, a phosphate material, and an inorganic material. The additive powder, when added to a curable or hardenable resin, forms a mixture where the additive powder is about 20-30%, by weight, of the mixture. The resin can be styrenic, olefinic, acrylic, cellulosic, polyester, or polyamide such as are commonly used in the manufacture of fiberglass reinforced structures and moldable plastics.

Abstract: An article conveying system including a conveyor belt having a plurality of slats movable along a slider bed. A nozzle system directs a water and detergent flush along the water bed beneath the conveyor belt to remove debris. A water tank and scrap basket collect and remove the debris and direct water to a drain. The slats have lower feet which engage a pair of plastic tracks and are removable for cleaning. The system is also provided with an anti-jam device.

Abstract: A ventilated conveyor oven is provided. The oven uses a makeup air fan to admit air to the plenum extending across the front of the unit and across the top of the unit. Exhaust channels are provided on the sides spaced above and below the conveyor oven entrance and exit and extending across the top to an exhaust fan outlet. The exhaust channels on the top are superimposed over the air makeup plenum. Vertical exhaust plenums are provided at each of three corners, with the fourth corner mounting a control panel and an air makeup external channel thereover.

Abstract: An electric current detector circuit for sensing a leakage of electrical current in a particular system and then providing a signal to control the operation of the system. The circuit is also adapted to receive a signal upon the occurrence of fire, in and around the system attached thereto, and then provide a signal to further control the operation of the system.

Abstract: A control circuit for a dishwashing machine to economize its energy consumption and usage. In order to conserve energy, the dishwashing machine has a control system for automatically actuating the components such as the heating elements of the dishwashing machine. The control system can easily be adapted for utilization with many types of existing dishwashing machines, thereby permitting coupling of the control system with commercially available equipment with minimum installation and alteration of machine components.

Abstract: An energy management system for limiting continuously instantaneous permissible power level of a plurality of controllable loads including a transducer device for generating an output signal when the measured instantaneous power level exceeds a pre-set instantaneous permissible power level. A programmable matrix device is provided to select a plurality of controllable loads and periods of time in a day for which each of the selected loads are connected to a power source. The selected controllable loads are disconnected from the power source in response to the output signal in a predetermined order. The order in which the selected loads are to be disconnected is sequentially switched over a certain time interval.

Abstract: A ground fault and fire detector system for an A.C. electrical power distribution apparatus including a multi-pole circuit interrupter to disconnect a poly-phase electrical power supply from a load. A single-pole circuit device is operatively connected to the circuit interrupter for controlling its operation. Ground fault sensing circuitry is operatively positioned with respect to at least one wire for initiating a fault current. The single-pole circuit device is responsive to the fault current for activating the circuit interrupter to disconnect the power supply from the load.

Abstract: A delay circuit includes a switching element for operatively switching between a first position and a second position. The switching element connects an input voltage to an electrically-operated device in the first position. A delay element is operatively connected to the switching element for maintaining the switching element in the first position when an input voltage interruption occurs which is less than a pre-determined time interval.
