Abstract: POINT SENSOR MOUNTING APPARATUS               ABSTRACT OF THE DISCLOSURE       A non-elastomeric sensor holding fixture using metal to sensor contact friction in a wheel slip control system maintains a wheel speed sensor in intimate contact with an exciter wheel without the excessive sensor wear which otherwise happens when the wheel speed sensor is held in place with resilient elastomeric holder.  The use of metal-to-sensor frictional contact in the holding fixture avoids the hardening and seizing normally occurring in elastomeric-to-sensor frictional contact due to time and allows readjustment of sensor posit ion after extended use.

Abstract: ABSTRACT OF THE DISCLOSURE Envelopes of air supported structures have previously been constructed of extremely heavy and strong materials usually far above and beyond the strength of the materials needed, which, in addition to materially increasing the costs, have increased the loading stresses inherent in maintaining static equilibrium in view of the increased pressures necessary to inflate and maintain inflation support of such extremely heavy enclosures.          Although the prior art have recognized that problems of load distribution existed in air supported structures, none teach how such structural loading is interrelated and how such load may be resolved in a manner to provide an air supported structure of static equilibrium.  In accordance with the present concept, a stress relieved air supported structure having a wall portion including a plurality of relatively elongated panel members joined together by seam means and restrained by harness means; anchor means being provided along the base perimeter of the wall portion; each of the panel members including a membrane configuration, adjoining panel members being joined together by a seam means and having web means interconnected thereto along the seam thereof, and wherein the load of the harness means, seam means, anchor means, and the load and stress of the membrane configurations thereof are a function of the width and height of the air supported structure, the primary radius of curvature thereof, and the design wind speed and inflation pressure thereof.  None of the prior teachings suggest the structural loading interrelationship and resolution of the same in the manner outlined by the present concept.

Abstract: ABSTRACT               A method of, and apparatus for, automatically wrapping in plastic film a shallow tray filled with irregularly-shaped contents such as meat or vegetables is provided. No elevator for tray movement is required yet the system forms a lap seal on the bottom of the tray with modern soft plastic films, including stretching and shrink films. The trays advance into a curtain of the plastic film arranged transversely to a tray feed track. A first air blower blows onto the film surface above the tray, billowing the film smoothly ahead of the tray to prevent folds from forming in the film and to keep moving air between the tray and the film during tray advance to avoid snagging therebetween. A lower edge of the film is captured between the tray bottom and tray support rollers. The film is draped over the top and back of the tray. A tucking device displaces the support rollers downwardly and tucks and forms a lap joint between the film ends beneath the stationary tray.  End folders then fold the tubed ends of the film upwardly to the sides of the tray and downwardly to the bottom of the tray prior to shrinking or final heat treatment of the film.

Abstract: ERROR CONTROL FOR DIGITAL    MULTIPOINT CIRCUITS   Abstract of the Disclosure A multipoint synchronous data network is formed by junction units which provide signal paths that inter-connect incoming branch lines to a common outgoing branch.          The junction unit is arranged to combine the branches so that data words on one branch are propagated up the common branch, subject to the condition that only one branch can send to the common branch at a time.  Each data word includes a designation whether the word carries message information or control information (such as an idle branch condition).  Control words are blocked by the junction unit so that message words from a sending branch are not garbled by control words from idle branches.  The junction unit passes each message word from a sending branch to the common branch if the junction unit had not priorly passed any message word to the common branch (presumably because all branches were idle) or if a message word priorly passed was from the sending branch whereby error conditions on idle branches simulating message words are not passed to garble the data from the sending branch.  This control is maintained by the sending branch for a plurality of word intervals after it has terminated sending data.                             - i -

Abstract: Abstract of the Disclosure A system is disclosed for controlling the pitch angle of helicopter rotor blades to compensate for differences in lift generated by advancing and retreating blades during translational flight or due to gust loading of individual blades.  Each rotor blade is free to move about its pitch axis to achieve an adjustable balance between a pitching moment exerted by the blade and centrifugal force exerted by weights rotating with the blade system.  Collective and cyclic pitch commands from the pilot are transmitted through a conventional swash plate to a linkage which adjusts the relationship of the pitching-moment and centrifugal forces which produces a balanced condition.  The system maintains near-constant blade lift as the blade rotates, and minimizes blade distortion and asymmetric coning, thereby significantly reducing vibration arising from a shifting of the center of mass of the rotor-blade system away from the center of rotation.

Abstract: CONFIGURATION AND CONTROL UNIT FOR A HETEROGENEOUS   MULTI-SYSTEM                  Abstract Of The Disclosure Describes a configuration and control unit (CACU) for a heterogeneous multi-system containing processors which may be of different types, channels, one or more channel crossbar switches which may be of different sizes, various I/O channel switches, I/O control units and I/O devices.          The CACU is the focal point in the multi-system for confi-guration control over all of these system heterogeneous components.  The CACU enables the configuration of any switchable part of the entire multi-system to be established and changed at any time due to new processing requirements or failure of part or all of the system.    The CACU contains a parallel wire line (PWL) adapter for providing DC switching control over components connected through channel crossbar switches and/or channel I/O switches.     The CACU also has a time multiplexed (TM) adapter connected via serial time multiplexed lines (TML's) to remote modem adapters (RM's) with devices controlled by or switched by the CACU.  A TML can provide serial pulse control switching for components connected to channel crossbar and/or channel I/O switches, which transfer data directly Prom the processor channels whereby the data bypasses the CACU.  A TML can also provide serial pulse data to other devices which have their data passed through and switched by the CACU for switchable communication with any processor.  A persistent storage unit is providable in the PWL adapter and TM adapter for perma-nently storing the current configuation of PWL and TML connected units.  Upon failure of any one or more units connected to the PWL adapter or TM adapter, the settings in the persistent storage devices can recover the operating configuration of devices in the multi-system.
