Abstract: Data processing apparatus includes a storage circuit or memory, and an addressing circuit for identifying word locations within the storage circuit into and from which a plurality of information items are to be written and read, respectively. Further, there is included an encoding circuit for encoding at least a part of each information item in one-out-of-n code, illustratively. In turn, the encoded part is successively shifted by a shift circuit so that it is stored in the storage circuit in a manner that the stored information in each word location has a bit order different from that order of any other information item as stored in the storage circuit. A translating or de-skewing circuit is provided for shifting the encoded data items as read out from the storage circuit in a direction opposite to that imparted by the first noted shift circuit.

Abstract: In a two-stage hovercraft skirt comprising an upper loop from which segments depend, operational movements of the skirt are effected by an adjusting tie extending at right angles and connected to generally radially directed ties by which the segments are secured to the hovercraft. By connecting the adjusting tie to the midpoint of the segment ties, holding the skirt against sympathetic movement with the adjusting tie and operating the latter by a lever system mechanically equivalent to the tie system the force required to cause movement of the skirt may be kept constant. Movements of the skirt may be used to cause or control rolling, pitching or heaving of the hovercraft.

One seal consists of a solid annular seal made of flexible material and placed near the outer edge of the enclosure. The other seal consists of a hollow and inflatable annular seal which is placed near the inner edge of the enclosure and is connected to a source of fluid under pressure by means of a closable duct.

Abstract: A sand cooler control system for a sand casting foundry system incorporates a cooling system positioned downstream of the shakeout station where castings are separated from the hot sand. The amount of cooling fluid utilized in the cooling process is controlled by a digital system responsive to the total heat (BTU) content of the sand as determined by a combined function of sand temperature and volume. The temperature and volume parameters are determined by non-contact sensors which take the form of an infrared sensor and sonic sensor, respectively.

Abstract: A support for integrated circuit chips to be mounted on an interconnecting base provided with conductive areas. The support consists of a flexible strip made of an inextensible insulating material having equidistant openings towards the center of each of which extend overhanging interface conductors electrically independent of each other. The free inner ends of the conductors in each opening correspond to that of the contact areas on a chip placed at the center of the opening, and each of the conductors has at a point along its overhanging portion, a contact region which is intended to be soldered to a corresponding conductive area on the said interconnecting base.

Abstract: A source in which the neutron fluence can be varied makes use of a (.alpha.,n) reaction between a radioactive emitter in powdered form and a target in fluid form. The emitter is immersed in the target fluid between an upper and lower filter within a closed chamber. When the emitter rests on the lower filter in the quiescent state, radiation is limited by self-absorption and the source is in the state of minimum fluence. When the target fluid is circulated by means of a booster, the emitter is fluidized and maximum fluence is achieved. Variable intermediate values can be obtained by regulating the pressure and rate of circulation of the target fluid.

Abstract: A semiconductor device having an ohmic contact including a metal layer of molybdenum or tungsten on a first polycrystalline silicon layer, is provided with a second polycrystalline silicon layer on the metal layer, to prevent the subsequent oxidation of the metal layer.

Abstract: An arrangement for sharing file information among plural processes in a multiprogrammed computing system. Source program file declarations are compiled into file control structures which are placed in skeletal segments, the segments forming units of potential sharing between active processes. Those segments which contain file control structures are placed in either the address space of (1) all processes, (2) related processes, or (3) a single process, depending upon the declared sharing level of the file. Job control language (JCL) commmands are expanded into JCL file control structures and merged with the source language structures to form a file request control structure. This request may be compared against a catalog of existing external files, a check being made to insure that the account on whose behalf a computing job is requesting file assignment is authorized to obtain the requested access to the file.

Abstract: Impregnation of a porous carbon body involving deposition of carbon from a as can be effected by establishing a thermal gradient across the body such that carbon is deposited at a boundary which advances through the body. The present furnace is for use in such a process and comprises a heater element with which, in use, the body is in contact and a cooled surface facing the element, characterized in that the latter surface is covered with a layer of thermal insulating material to reduce the thermal gradient across the body. This improves the economy of the process. The insulating material is suitably fibrous, eg graphite felt, and is protected by a layer of relatively low permeability, eg graphite sheet, to prevent deposition of carbon which would reduce its insulation properties.

Abstract: A cylindrical inner vessel containing the reactor core is placed coaxially within a main vessel. Heat exchangers are disposed within the annular space formed between the two vessels, each heat exchanger being delimited by an outer shell and a coaxial inner shell which surrounds a central feed duct having a vertical axis. The upper end of the annular space communicates with a flared end portion of the central duct through a first circular window formed in the inner shell. The lower end of the annular space communicates with the region located between the inner vessel and the main vessel through a second circular window formed in the outer shell.

Abstract: The speed of an elevator is controlled and adjusted by utilizing a differential voltage obtained from a variable voltage indicating actual speed and a control voltage reflecting an ideal curve of speed variation. The resulting voltage or reference curve has a series of straight sections corresponding to distance lengths decoded from a distance counter for the distance travelled from the giving of a slowing order at a fixed distance from the stopping point. Each control section has it origin realigned with the reference curve.
