Abstract: An improved flat roof structive is provided comprising a substructure and a plurality of insulating elements which are loosely positioned on the substructure. A corrugated cover member of a substantially rigid material is positioned on the insulating elements at least in an area adjacent the outer perimeter of the roof. The corrugated cover member has downwardly facing channels which extend in a direction generally from an outer perimeter towards the center of a roof. The channels are open at their ends facing the perimeter of the roof and are closed or sealed at their ends facing toward the center of the roof. A strong air flow will create a vacuum under the cover member in wide areas which reduction is greater than the vacuum on the upper surface of the cover member whereby the cover member is pressed downwardly against the insulating elements. Due to the nearly uniform vacuum under the cover member, i.e. on the upper surface of the insulating elements, the resultant force which acts in the direction of lift-off on the insulating elements is nearly zero.

Abstract: APPARATUS FOR AIR ARC GOUGING                          Abstract An air arc gouger. A central power supply (10) and a welding station (11) are used for welding operations, such as welding two metal plates (30A, 30B) together. If a weld (30C) is required to be removed, an adapter circuit (12), in conjunction with the central power supply (10) and the welding station (11), are used. The adapter circuit (12) need only supply the difference between the current required to maintain the gouging arc (31) and the maximum continuous output current of the welding station (11). The adapter circuit (12) is smaller, less expensive, lighter, more portable, and generates less heat than a conventional resistor grid.

Title: Master slave industrial token passing network
Inventor: MARRIOTT JEFFERY CARL
IPC: H04L12/417
Filed: 1990-11-22
Granted: 2001-02-13
Abstract: A communications network is comprised of master and slave stations. The master stations may receive a master token allowing control of the network for sending messages, and a solicit token that allowing the master stations to solicit other master stations for entry into the network.      A master station receiving a solicit message answers with an acknowledgement signal and may immediately begin soliciting for successors. The slave stations receiving a solicit message may not accept the master token ar the solicit token but must respond with a negative acknowledgement. Slave stations enter the network to respond to messages only. The use of slave stations allows for the implementation of simpler networks and improves network efficiency. The negative acknowledgement identifies the presence of the slave stations and allows detection of duplicate network nodes.

Title: Safety device and method
Inventor: PELKEY MARK J
IPC: G05D16/16
Filed: 1991-02-05
Granted: 1996-12-17
Abstract: The invention relates to a gas pressure safety device used in the natural gas distribution systems leading to homes or other customers. This safety device is connected to a gas venting device that allows excess gas to exit therefrom. The safety device is made up of a needle valve, a pressure sensing pilot and a spring-diaphragm actuator. The needle valve is used to restrict the rate of gas flow into the actuator to a rate less than that that can be vented by the pressure sensing pilot. When an excess pressure is generated in the distribution system, the pressure sensing pilot senses when to exhaust the excess gas through the actuator and out of the gas venting device to the atmosphere.

Abstract: Composite products, comprising a wad of fibrous material sandwiched between a non-woven fabric carrier and a liquid-impervious backing are formed by forming the wad on the carrier, moulding the wad and carrier to have a desired configuration, stabilizing the wad and bonding it to the carrier, applying the backing and cutting the wad with a border of carrier and backing from the rest of the carrier and the backing. The carrier is sheet-like and a number of the wads are formed thereon in a continuous manner. The wads are stabilized by means of a foamed acrylic binder that is sprayed onto the wads and sucked through the wads and onto the carrier by a suction applied to the underneath of the carrier. The wads and carrier are then heated to cure the binder. Instead, the wad can include thermoplastic particles so that the wad is stabilized and bonded by being heated.
