Abstract: A DYNAMIC INTERNAL FITTING SYSTEM FOR A SPORT SHOE              ABSTRACT     A Dynamic internal fitting system for a sport shoe is described.  In a typical embodiment such as a ski boot, the sport shoe has a lower shell member and an upper cuff member.  Interior of the shell and cuff member in a downhill ski boot, there is provided a pair of strap members for engaging the lateral and dorsal aspects of a foot.  One end of the strap members is at-tached to the sole of the ski boot.  The opposite end of the strap members is connected to one end of a cable by means of a pivotable linking member.  The cable extends from the linking member and is connected at its opposite end to a pulley.  The pulley is releasably coupled to the cuff member and means are provided for manually selectively adjusting the length of the cable wrapped about the pulley.  In fitting the ski boot, as the length of cable wrapped about the pulley is adjusted, the linking member moves and pivots to accom-modate the strap members to the foot size and shape.  During skiing maneuvers, as the position of the foot changes in the boot, the linking member pivots for dynamically adjusting the tension applied to and the position of the strap members relative to the foot engaged thereby.  Additionally, as the cuff member pivots relative to the shell member, the pulley rotates with the cuff member.  The length of cable wrapped about the pulley then varies dynamically for further dynamically moving and pivoting the linking member for adjusting the tension applied to and the position of the strap members relative to the foot.   In an alternative embodiment, the pulley is releasably coupled to the shell member and does not rotate with the cuff member.   In another embodiment in a ski boot, there is provided a tongue member, a pair of cables extending from opposite lateral sides of the tongue member, and a pair of pulleys coupled to the opposite sides of an upper cuff member.  Each of the cables is connected to a separate pulley.  The pulleys are releasably coupled to the cuff member and rotate with the cuff member for dynamically adjusting the tension applied to and the position of the tongue member relative to the foot engaged thereby.  In one embodiment, each of the pulleys is separately adjusted relative to the cuff member for adjusting the tension applied to and the position of the tongue member relative to the foot.. In an alternative embodiment, both of the pulleys are connected to a common shaft and are adjusted together relative to the cuff member.

Abstract: METHOD OF AND APPARATUS FOR INDICATING A TYPE AND REMAINING         RECORDING CAPACITY OF A RECORDING TAPE               ABSTRACT OF THE DISCLOSURE           A method and apparatus for indicating the type,such as in terms of overall recording capacity, and remaining recording capacity of a recording tape.  The tape is transported at a predetermined speed from a supply reel to a take-up reel.          The rotations of the respective reels are sensed and the rota-tional periods Ts and Tt of the supply and take-up reels, respec-tively, are determined.  Based upon these determined rotational periods, predetermined characteristics, such as the overall recording capacity, of the recording tape are indicated, irre-spective of the arbitrary amount of tape which, initially, is wound upon the take-up reel.  For example, a set of character-istics is stored for each value of  ; and the one set which is associated with the determined value   is selected. Also, the determined rotational periods Ts and Tt are combined with certain of said characteristics to indicate the amount of tape which remains upon the supply reel when that amount initially is unknown.  The latter operation is carried out in accordance with the expression  , wherein TR represents the recording capacity of the taps which remains on the supply reel,  , and P and Q are constant values associated with the type of tape which is used and are determined by the diameter of the supply (or take-up) reel hub, the total length of recording tape, the thickness of the tape, and the speed at which the tape is driven.     -i-

Abstract: 735.062-FOREIGN     METHOD AND APPARATUS FOR MONITORING AND CONTROLLING A    MULTIPLICITY OF AIR GUNS FOR SEISMIC SURVEYING     Inventor: Stephen V. Chelminski ABSTRACT OF THE DISCLOSURE           Firing a seismic source of the type called an air gun is detected by means of a fluid pressure sensor transduce located in the housing of a solenoid actuated control valve.          Through a pressurized gas supply port the pressure sensor is in fluid communication with a shuttle-operating chamber of the air gun, and the sensor detects a surge or increase in fluid pressure in a portion of shuttle-operating chamber resulting from rapid motion of the shuttle thereby providing an elec-trical signal which is an accurate indication of the actual time of firing, called the "shot instant" of the air gun. Thus, the geophysical survey crew is enabled to determine the actual shot instant of each air gun in an array of air guns, so that their respective shot instants can be synchronized, sequenced, or otherwise controlled in accordance with a desired seismic survey program.  If a misfire or malfunction of the air gun is detected by means of this fluid pressure sensor, the malfunc-tioning air gun can be shut down by actuating the solenoid valve, which is a novel dual action solenoid valve, thereby prevent-ing pressurized gas from being supplied to that particular air gun. The valve includes a valve stem with radial gas inlet ports and radial triggering ports. A solenoid plunger is movable to close one or the other of the sets of ports. A cham-fered seal-engaging lip and shoulder on the plunger are in fluid contact with the gas inlet port and pressure forces on the lip and shoulder are balanced to reduce the  electrical power requirements of the solenoid.

Abstract: A B S T R A C T         Apparatus for feeding at a variable controlled rate particulate solid material, such as coal, from a supply lo-cated above a gravimetric feeder to a discharge chute located below the feeder.  The particulate material flows to the feeder from the supply along a path having a generally vertical center line and the discharge chute provides a flow path having a gen-erally vertical center line closely laterally spaced relative to the center line of flow to the feeder.  The feeder apparatus has a horizontally extending housing with an upwardly facing inlet, through which the material flows to the feeder, and a downwardly facing outlet forming part of the discharge chute through which the material flows from the feeder.  Within the housing is a main feeder conveyor comprising an endless belt with a generally horizontal span adapted to receive at one end the particulate material flowing to the feeder and to convey in a layer a measured quantity of material horizontally across weighing means to an exit zone at the opposite end of the belt, the horizontal distance being necessarily greater than the spacing between the center lines of flow to the feeder and through the discharge chute.  A gravimetric control system for controlling the amount of material deposited on the belt is associated with the main feeder conveyor.  Particulate material that drops off the main conveyor belt at the exit zone is re-ceived on a return belt conveyor and carried in a reverse di-rection a sufficient distance to bring the material to the dis-charge chute.  Cooperation between the main feeder conveyor and the return conveyor permits gravimetric feeding of partic-ulate material to a discharge chute that is closely laterally spaced from the flow path of material to the main conveyor by a distance that is substantially less than the length of travel of the material on the main conveyor.

Abstract: AUTOMATIC MARGIN SETTING APPARATUS    FOR A SCANNED SHEET OF PAPER                            Abstract In a typewriter environment, a carrier mounted sensor for calculating the width of a sheet of paper on the platen and for thereafter setting-up margins for that sheet of paper.  In addition to supporting the sensor, the carrier supports the printhead and associated apparatus for detecting the position of the carrier relative to the platen at each escapement position of the carrier.  The sensor starts its scan at the extreme left position of the carrier and senses the left edge of the paper at a transition from dark-(the platen surface) to-light (the sheet of paper).  This transition point is detected and stored.  The carrier continues its rightward scan and the right edge of the sheet of paper signals a transition from light-to-dark. This position is detected and stored.  The carrier and sensor continue scanning to the right for a specific distance to eliminate errors that are caused by dark areas on the paper that prematurely trigger light-to-dark tran-sitions.  At the end of the scan, the recorded distances yield the width of the sheet of paper and from this re-corded width, margins of a predetermined size are set.
