Abstract: A B S T R A C T :     A system for conveying and storing newly pressed cheeses, comprising a plurality of shelves made as conveyor units each comprising a row of crosswise disposed carrier bars, of which some are cyclically movable so as to cause the cheeses to be displaceable along the shelf structure. The cheeses may thus be fed to and moved away from respective storing positions on the shelves by the conveyor action of the shelves themselves, and during the storing whether in air or in a liquid the cheeses may be slowly reciprocated to avoid surface deformation thereof and allow free access to all surface portions thereof. When used in combination with a brine vat the conveyor shelves will support the un-derlying cheeses because of their buoyancy in the brine, but the cyclically movable bars act as a conveying means on both the top side and the underside of the shelf, to enable reciprocation even of cheeses submerged in brine.

Abstract: LOW NOISE MULTISTAGE AVALANCHE PHOTODETECTOR           Abstract of the Disclosure Devices constructed according to the present invention provide low noise avalanche photodetectors. The devices are comprised of a sequence of at least four layers                  of semiconductor material of alternating opposed conductivity.  In a first embodiments the layers form alternating homojunctions and heterojunctions at the interface between adjacent layers, and the bandgap of the layers on either side of the homojunctions decreases in the direction of the propagating signal.  In another embodiment, the layers form heterojunctions at the interfaces between adjacent layers; the layers are grouped into a sequence of pairs of layers where the bandgap of the two layers in  each pair are substantially equal; and the bandgap of the layers in the sequence of pairs of layers decreases in the direction of the propagating signal.  The effect of the structure of the multilayer device is to create traps for one sign of carrier and to prevent the trapped carrier from avalanching through amplification regions of the device.

Abstract: ABSTRACT OF THE DISCLOSURE           A programmable sequencer is disclosed in which a microcomputer is employed to selectively energize patterns of a plurality of relays in a programmed sequence of patterns or steps. The micro-computer is programmed by selecting a memory location to correspond to a predetermined desired sequence. A plurality of light emitting diodes are mounted on a front panel of the sequencer to correspond to the plurality of relays to be programmably energized. The light emitting diodes are sequentially and individually illuminated, each for a predetermined period of time, for each step of a sequence to be programmed. An operator selects one or more of the relays to be energized during the step being programmed (corresponding to the pattern) by mani-pulation of a switch during the time the relays corresponding light emitting diode is illuminated. After all of the light emitting diodes have been illuminated, a time interval is selected for the step being programmed. After all of the light emitting diodes have been illuminated and the time interval is selected, an advance button is pressed which transmits information corresponding to the desired step into the memory location selected and allows the repetition of the above steps until a program is completed. After the program or programs desired are programmed in the above fashion, the sequencer may be switched to a run mode and any one of the programs can be implemented.

Abstract: METHOD AND DEVICE FOR CONTROLLING                RAILROAD CAR BODY ROLL               Abstract of the Disclosure An arrangement and method for controlling car body roll in high capacity railroad freight cars, in accordance with which a hydro-pneumatic roll control unit is incorporated in the car truck spring groups that support. the respective truck bolsters.  The roll control unit comprises a base housing defining a lower or outer cylinder having an upstanding piston rod structure equipped with a piston head that reciprocably mounts a tubular ram having a ram head that operates in the outer cylinder and defines an upper or inner cylinder in which the base housing piston head operates. An annular rolling seal is received in circumambient relation about and connected to both cylinders in invaginating leak free relation thereto, which defines an annular reservoir about said cylinders with which both cylinders have communication.  The cylinders and the reservoir are given a hydraulic liquid charge sufficient to fully fill the two cylinders and the lower portion of the reservoir and a gas charge within the reservoir that forms a pressurized gas pocket above the level of the hydraulic liquid charge in the reservoir.          The gas charge maintains the unit in constant contact with the bolster and side frame seats.  In functioning to control body roll, both cylinders resist roll under constant pressure conditions while the outer or lower cylinder provides supplemental resistance under velocity sensitive conditions, with the hydraulic liquid cycling through the hydraulic system of the unit as the unit operates as part of a bolster spring group.

A reducing agent such as pit coal is injected together with a oxidant into the hot gas from the plasma burner so as to form a gas mixture mainly comprising CO and H2, which gas mixture is then mixed with the other flow portion of the cleaned reaction gas in such a proportion that the temperature of the resulting reduction gas is suitable for the reduction of iron oxides in the shaft furnace.  The reduction gas is then injected into the shaft furnace and passed upwardly to reduce iron oxides contained there to form sponge iron which is then removed.
