Abstract: STEAM PROCESSOR                               ABSTRACT A steam processor for preparing or warming food items. The processor includes a cooking chamber having a steam inlet and outlet, and an adjacent steam generator for supplying steam to the chamber.  The steam generator includes a water level control system for maintaining a water level within the generator within predetermined limits and an immersion heater for vaporizing the water.  A steam control is provided that regulates the heater to control the rate at which steam is produced and flows into the cooking chamber.  The processor includes an automatic drain feature which discharges any water within the steam generator whenever power to the processor is terminated.  A steam condenser that condenses steam exhausted by the chamber is disposed near the outlet of the cooking chamber. The condenser precipitates a sub-atmospheric pressure at the outlet which serves to purge air from the chamber and enhance the flow of steam into the chamber. The water supply for the steam generator flows through a pre-conditioner which pretreats the water to minimize the formation of deposits in the steam generator and associated plumbing.

Abstract: Case 210 METALLIC SEAT ASSEMBLY FOR VALVES        John M. Hinrichs Bryan, Texas Abstract of the Disclosure A valve seat assembly adapted to fit within an annular groove in a butterfly valve body.  The seat assembly includes a pair of opposed metal seat rings generally L-shaped in cross section with overlapping outer legs seated and anchored in the bottom of the groove.  The seat rings have flex-ble free inner end portions extending radially inwardly of the groove termina-ting at outwardly curled arcuate ends which contact the sealing surface of the valve disc and extend laterally of the groove in spaced relation to an over the adjacent valve body.  A resilient soft seal is mounted between the metal seat rings and the sides of the metal seal rings are corrugated to grip and retain the soft seal in place.  The end portions of each metal ring have a relatively long free length and are easily flexed laterally and radially out-wardly of the valve body by contact with the outer periphery of the disc when the disc is moved to a closed position to maintain sealing contact with the disc without requiring a high operating torque.

Abstract: ABSTRACT A machine for cutting grooves in foam workpieces includes a plur-ality of vertically spaced U-shaped cutting wires mounted on pairs of mounting posts.  One leg of each U-shaped wire is mounted on one post, while the other leg is mounted on the other post.  The posts are mounted on a frame so as to be adjustable in spacing and vertical position with re-spect to each other, so the widths of the grooves can thereby be adjusted. Horizontal slice-cutting wires are provided behind the groove-cutting wires so that grooves and slices can be cut simultaneously.  The slice-cutting wires are aligned at an angle with the vertical so that each slice-cutting wire exits the workpiece before all those beneath it.  One version produces tongue-and-groove sheet, while ship-lap sheets are produced by the other version.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the direct production of steel from particulate iron oxides or concentrates including two major steps in which in Step (1) the iron oxides are converted to iron carbide and in Step (2) steel is produced directly from the carbide in the basic oxygen furnace or the electric furnace. In the production of the carbide the oxides are reduced and carburized in a single operation using a mixture of hydrogen as a reducing agent and carbon bearing substances such as propane primarily as carburizing agents.  Iron carbide thus produced is introduced as all or part of the charge into a basic oxygen furnace to produce steel directly without the blast furnace step.  In order to make the steel making process auto-thermal, heat is supplied either by using the hot iron carbide from Step (1) or preheating the iron carbide or by including sufficient fuel in the iron carbide to supply the required heat by combustion.

Abstract: OPERATION OF ASSOCIATED                   CRUSHING PLANT AND MILL                  Abstract of the Disclosure A method for operating a crushing and grinding facility is disclosed in which crushing of mine-run material is controlled to always match grinding feed requirements while both crusher(s) (10) and grinding mills (16) operate full time and draw full power during the hours of what may be unequal length working days.  The grinding mill (16) is also operated to produce the maximum output of final product that is within its existing capabilities.  At each of a succession of measurement times (e.g., every 1/2 hour during a 22-hour working day of the mill), the rate of production of final product by the grinding mill (6) is ascertained (as by 21, 22, 23) and projected to the end of the mill working day.  At each such time, feed of mine-run material to the crusher (10) is adjusted (as by 27-33, 11) to a rate which, if maintained through the remaining portion of an 18-hour crusher working day, would cause production of a target quantity of crushed product (at 8) which would equal projected total daily production of ground product (at 9). However, the mill (16) will not maintain its prevailing rate of production because grindability of crushed material is unpredictably variable.  Therefore, the projected 22-hour daily production of mill final product (at 9) is redeter-mined at the end of each time interval and is the basis for a new target for crusher production.

Abstract: ABSTRACT OF THE DISCLOSURE     A gate valve is installed in a sewer line or drain pipe extending from a house or other building to a street sewer pipe or the like which will automatically close when sewage backs up from the street sewer pipe toward the house or building structure, thereby protecting the basement or other lower portions of the house or building structure from becoming flooded due to sewer backup.  The gate valve is motor actuated and includes a vertically reciprocal gate controlled by a float operated switch structure disposed downstream of the gate valve to quickly and positively move the gate to fully closed position upon flood conditions existing in the lateral sewer pipe downstream of the gate valve thereby preventing back flow and flood conditions occurring on the house side or upstream of the gate valve.  A motor operated pump and chopper unit communicates with the sewer pipe on the house side of the gate valve and discharges through a bypass line with a one-way flap valve therein to the street side of the gate valve in order to pump sewage around the gate valve when it is closed thereby enabling sewage to be discharged from the house side of the gate valve to the street side of the gate valve even when the gate valve is closed thereby enabling normal operation of the facilities in the house or other building which discharge sewage into the sewer line.

The fluid pressure control system controls the com-munication of pressurized fluid to the effective pres-sure areas to provide both the brake applying and brake releasing functions.  Redundant fluid pressure circuits supply pressurized fluid to the brake applying effec-tive pressure areas.  In the event of failure, the control system is operative to interrupt fluid flow to the failed circuit.
