Abstract: Abstract of the Disclosure The invention provides a distribution and heating method for foodstuffs and an inexpensive disposable microwave shipping, heating and serving package for food composed of a paperboard carton and a lossy microwave energy absorber which becomes hot when exposed to microwave radiation.  The absorber is associated in conductive heat transfer relationship with a food product contained in the package and is usually bonded to a structural supporting sheet such as aluminum foil.  The package also includes a shield e.g., a metal foil sheet adapted to reduce by a controlled amount the direct transmission of microwave energy into the food product.  The shield may have holes of a selected size-to provide a predetermined controlled amount of direct microwave energy to the food product or can be a nonperforated sheet or screen.  The absorber heats the adjacent surface of the food by conduction to a sufficiently high temperature to provide searing or browning while controlled microwave exposure heats the inside.  The thickness of the absorber is substantially in the range wherein absorber thickness and temperature response are positively correlated.

Abstract: ABSTRACT OF THE DISCLOSURE     Coal to be supplied to a coking oven is pre-heated, in a single pre-heating zone, such as in a conveying riser, first by heat yielded to it by a gaseous carrier medium entraining the coal for joint passage through the riser, and then additionally pre-heated by heat yielded to it by a gaseous fluid, such as hot combustion products, introduced into the pre-heating zone at a region thereof at which the temperature of the coal has already risen to a predetermined value, such as 80 to 100°C. The additional pre-heating of the coal results in a final temperature of the latter at the exit of the riser of more than 130°C, preferably between 150 and 250°C. The stream of the carrier medium with the coal entrained therein flows upwardly through the riser which is substantially vertical, the coal being entrained at the lower end and separated from the mixture of the carrier medium with the gaseous fluid at the upper end of the riser. A part of the above-mentioned mixture may be circulated to the lower end of the riser for use as the carrier medium. The flow-through cross-sectional area of the pre-heating zone may be larger downstream than upstream of the region at which the gaseous fluid is introduced for maintain-ing the speed of flow through the pre-heating zone constant despite the addition of the gaseous fluid.

Abstract: ABSTRACT      A power supply provides a low-level DC voltage to one or more DC load circuits by first rectifying either of the two standard AC voltages and thereafter reducing the rectified AC voltage to the low-level DC voltage.  The reduction of the rectified AC voltage to the low-level DC voltage is accomplished by a power transformer which is switched on or off by a pair of switching transistors.          The switching transistors are activated by a control transformer operating in combination with a control circuit.          The control circuit timely produces various pulse conditions in the control transformer which turns the switching transistors on or off in a prescribed manner.

Abstract: ABSTRACT OF THE DISCLOSURE              An invention involving a process and apparatus for isotope-separation applications such as uranium-isotope enrichment is disclosed which employs cascades of gas centrifuges.  A pre-ferred apparatus relates to an isotope-enrichment unit which includes a first group of cascades of gas centrifuges and an auxiliary cascade.  Each cascade has an input., a light-fraction output, and a heavy-fraction output for separating a gaseous-mixture feed including a compound of a light nuclear isotope and   . a compound of a heavy nuclear isotope into light and heavy frac-tions respectively enriched and depleted in the light isotope.          The cascades of the first group have at least one enriching stage and at least one stripping stage.  An example of such a gaseous mixture is uranium hexafluoride incorporating uranium-235 and uranium-238,  The unit further includes means for introducing a gaseous-mixture feedstock into each input of the first group of cascades, means for withdrawing at least a portion of a product fraction from the light-fraction outputs of the first group of cascades, and means for withdrawing at least a portion of a waste fraction from the heavy-fraction outputs of the first group of cascades.  The isotope-enrichment unit also includes a means fox conveying a gaseous-mixture from a light-fraction output of a first cascade included in the first group to the input of the auxiliary cascade so that at least a portion of a light gaseous-mixture fraction produced by the first group of cascades is further separated into a light and a heavy fraction by the auxiliary cascade.  At least a portion of a product fraction is withdrawn from the light fraction output of the auxiliary cascade.  If the light-fraction output of the first cascade and the heavy-fraction output of the auxiliary cascade are recipro-cal outputs, the concentration of the light isotope in the heavy fraction produced by the auxiliary cascade essentially equals the concentration of the light isotope in the gaseous-mixture feedstock.     l              ~    .    .....

Abstract: RAIL HOUSE CAR DOOR WEAR SKIDS                 Abstract of the Disclosure A rail house car with side openings and doors for closing the openings by movement of the doors longitudinally along the car sides and laterally into and out of the openings.  Cranks moveably support and retain the doors on longitudinal tracks below the doors and within longitudinal retainers above the doors.  The cranks are selectively manually driven for lateral move-ment of the doors.  The top cranks include combination skid and roller devices which permit the doors to move easily because of the rollers when they are longitudinally moved along the tracks and retainers but which permit the locating of the rollers within recesses in the surfaces of the retainers when the doors are located laterally substantially within their openings along the car sides.  The skids provide minimal wear of the surfaces of the retainers when the doors are so located because of the relatively large areas of the skid surfaces in face to face engagement with the retainers' surface portions adjacent the recesses as compared to wear normally created by the rollers' tangential lines of contact with the retainers' surfaces.  This wear is usually present in those situations where insufficient structural support for the roof causes vertical vibrations in the longitudinal retainers.  The skid and roller combination is also associated with any auxiliary cranks which are in engagement with surfaces of the longitudinal retainers.
