Abstract: BOTTOM UNLOADING MECHANISM   FOR A STORAGE STRUCTURE Abstract of the Disclosure A bottom unloading mechanism for unloading generally free flowing material from a silo or storage structure.  The unloader includes a sweep auger mounted to rotate about the center of the silo and undercut the stored material and convey it to the center of the silo where it is delivered to a discharge auger that operates in a radially extending trough in the silo foundation. The sweep auger is mounted on a turntable and is rotated about the silo in increments by a ratchet and pawl mech-anism which interconnects a drive unit on the outside of the silo with a drive shaft.  The inner end of the drive shaft carries a sprocket that engages a series of drive pins on the turntable to rotate the turntable and sweep auger.  The turntable is provided with a plurality of holes located between the drive pins, and the teeth of the sprocket act to force stored material through the holes to prevent clogging of the drive pins.  Rota-tion of the discharge auger is transmitted through a vertical drive shaft located in the inner end of the trough to the sweep auger to rotate the sweep auger about its axis.  A rotating slinger is located on the vertical shaft and aids in the delivery of the stored material to the discharge auger.  The sweep auger is composed of a series of shaft sections of different diameter with the innermost shaft section having the largest diameter.  A helical flight is associated with each shaft section and the flight on each section has a progressively varying radial depth to provide a uniformly increasing rate of delivery in a direction toward the inner end of the sweep auger.

Abstract: ABSTRACT OF THE DISCLOSURE            A data-processing system is connected to a peripheral system by a plurality of channel paths.  These channel paths are named as members of path groups.  Each path group has one or more channel paths.  Within each path group,  communications  between  the  data-processing system and the peripheral system are multipathed among the paths in such path groups.  Devices within the peripheral system are selectively assignable to access groups for exclusive use within one or more of such path groups;  a given path group  selectively provides communication paths for each device in an access group. Each access group includes one or more path groups. Temporary suspension and reassignment facilities are disclosed. Both devices and channel paths can be either in a grouped or ungrouped state. The assignment function to access groups is particularly useful in interleaved channel transfers for ensuring subsystem integrity.

Abstract: Abstract Disclosed is a microwave lens of low weight and cost which may be used in communication satellites.  The lens can be used with a simple feed, such as a horn, and achieves low cross-polarization levels.  Flush mounting of the lens is possible.  The lens comprises a plurality of parallel flat supports of dielectric material, each carrying at least one array of commonly orientated conductive dipole elements arranged in regularly spaced rows and columns.  For circular polarization, crossed dipole elements can be provided.          The supports may be formed of glass fibers and resin or plastic.  Each dipole array can produce either positive or negative phase shift depending on the frequency of operation.          By suitably scaling an array, the phase and phase versus frequency can be chosen at a given frequency.  The phase, phase versus frequency, and attenuation characteristics can be controlled by choosing suitable scale factors, the required number of arrays, and their physical separation.

Abstract: ABSTRACT            A railway bogie is disclosed with wheels of high effective conicity and supported on the wheels through pads with low yaw constraint so that they are self-steering.  Cross-members connect diagonally opposed wheels interconnect yawing movements of the wheelset in opposite senses to counteract the tendency to hunt.  Wheels on the same side of the bogie are connected by links pivoted on a lever pivoted on the bogie frame at one end and on the bearings of the wheelsets at the other end.  This interconnection inhibits the bogies frame from moving longitudinally when braking or traction forces are present and ensures that yawing movements of the frame are effectively transmitted through the wheelsets and thence to the wheel/rail contact area.

Abstract: ABSTRACT      An attachment is provided for allowing a chain saw sharpener to be used for filing the depth gauge portions of the cutting links on the saw chain.          The sharpener is of the type comprising a sharpener body in the form of an inverted U-shaped channel-defining member adapted to be placed over the bar of a chain saw, and a rotary burr with an abradant end portion which is receivable in a selected one of two horizontal guide bores provided in the sharpener body.  The depth gauge attachment comprises an elongated gauge bar and means for removably affixing the gauge bar within the upper portion of the shar-pener body channel so that the gauge bar occupies only a portion of the channel length.  The thickness of the gauge bar is such that it causes the saw chain to assume a sufficiently lower position within the sharpener body channel to bring the top of the depth gauge portion of a cutting link into contact with the abradant end portion of the rotary burr when the latter is inserted into a selected one of the two guide bores.  A protective hand slide is also provided for allowing the saw chain to be manually advanced during the depth gauge filing operation.

Abstract: Abstract of the Disclosure An adaptive interference cancelling system for multi-bit spread spectrum noise codes wherein a plurality of users in a mobile subscriber access system each operates with a different noise code.  Each user receives a composite signal which includes a desired noise coded signal from another user plus any unwanted interference noise coded signals from other like users in relatively close proximity.  The RF demodulator or front end section of each user receiver is coupled to a bank of matched filters which selectively detect and identify any interfering codes.  These interfering codes are then regenerated devoid of the desired signal to provide a coherent replica of the interference signal.          The received composite signal and the coherent replica of one or more interference signals are applied to individual signal subtractor circuits which operate to cancel the interfering noise coded signals leaving the desired signal to be subsequently matched filter detected free of interference from other users.
