Abstract: POWER TRANSMISSION                  Abstract of the Disclosure An electro-hydraulic servo valve system comprising a two-stage spool type servo valve including a first stage comprising an electrical force motor and a second stage including a spool for controlling flow to an actu-ator.  The force motor is operable upon receipt of a com-mand electrical signal to move the spool.  A first feed-back is operable to cause the force motor to stop the movement of the spool.  A second feedback is also operable to stop the movement of the spool at a predetermined posi-tion.  The second feedback has a greater gain than said first feedback so that it normally dominates in the system. The second feedback comprises a pair of identical electrical sensors connected in parallel, and operable by movement of the spool.  A comparator circuit compares the electrical signals from the sensors and is operable when the signals deviate from one another by a predetermined amount to disable the second feedback so that the first feedback will function permitting the electro-hydraulic servo valve system to operate without the second feedback.

Abstract: 27284-3?     ABSTRACT         A decoder for forward-error-correcting (FEC) convolutional codes.  The decoder uses the Viterbi algorithm for decoding the rate ?,constraint length 7 code with generator polynomials x6+x5+ x3+x2+1, and x6+x3+x2+x+1.  The architecture of the instant decoder is appropriate for implementation on a single monolithic VLSI integrated circuit chip and includes a branch metric calculator circuit which produces output signals representative of input sym-bol signals.  These output signals are supplied to a metric update circuit which evaluates the signals from the calculator circuit and provides decisions to a path update circuit which converges the signals thereto and the output signals of which are evaluated by a majority vote circuit which produces data output signals repre-sentative of data input signals.

Abstract: TEMPERATURE COMPENSATION FOR LIQUID FILLED PRESSURE GAUGE Abstract of the Disclosure A liquid filled pressure gauge in which temperature induced volumetric changes imposed on the liquid fill are compensated for by a tensioned flexible diaphragm secured in a pressure-tight spaced relation on a cover plate for the gauge casing.  For receiving the diaphragm pre-tensioned, the cover includes an annulus extending laterally from the cover surface with a negative draft on its circumference. By virtue of the diametral relationship between the outside diameter of the diaphragm about the draft surface of the annulus and the internal diameter of the case opening, the diaphragm incurs a friction fit as the cover is emplaced causing diaphragm tension to be increased.

Abstract: ABSTRACT OF THE DISCLOSURE     In an apparatus for forming leak-proof joints between tubes and a tube sheet by the internal application of hydraulic swaging pressure, the flow of relatively low pressure fluid from a pressure source to an intensifier is permitted or interrupted by a control valve.  During a prefill period, a prefill valve causes the low pressure fluid to bypass the low pressure input side of the intensi-fier and flow directly to the high pressure side and then to a mandrel.  Thereafter, the low pressure fluid is caused to enter the low pressure side of the intensifier to increase the pressure in the mandrel during a swaging period. A pressurization sensor, which is connected to the input and output sides of the prefill valve, contains a piston which is movable in response to the difference in the pressures at these two points to produce a termination signal which, after a delay, actuates the control signal at the end of the swaging period.

Abstract: ABSTRACT OF THE DISCLOSURE The dipstick has an enlarged head and an integral, flexible. shank which extends slidably through the dipstick tube of a conventional engine crankcase so that a pair of spaced thermistors, which are mounted on the shank adjacent its inner end, normally will be immersed beneath the level of the oil in the crankcase.  The shank contains a ground con-ductor which is connected adjacent one end to one side of the thermistors, and adjacent its opposite end has sliding,resilient engagement with the inside of the dipstick tube.  The opposite sides of the thermistors are connected by two additional conductors which extend upwardly in the shank to register with a pair of openings that are formed in diametrally sides of the shank near the dipstick head.  A clamp, which is secured to the outer end of the dipstick tube, carries a pair of spaced terminals, the inner ends of which project through the opposed openings in the dipstick and slidably and resiliently into engagement with the upper ends of the two conductors, when the dipstick is seated in the dipstick tube.  The opposite ends of these two terminals are releasably connected to an indicator circuit which produces an alarm signal when the temperature differential detected by the two thermistors exceeds a predetermined value.

Abstract: ELECTRONIC MEASUREMENT OF FREQUENCY VARIATIONS ABSTRACT OF THE DISCLOSURE         An electronic circuit receives an input of voltage pulses whose frequency of a predetermined range represents a variable to be manifested.  The first train of pulses of varying frequency is applied to a one-shot monostable multivibrator which produces a second train of pulses, each of which has a duration representa-tive of the maximum frequency of the predetermined range.  The out-put of the one-shot controls a gate through which passes a third train of pulses of constant frequency and shape between the pulses of the second train.  Counting, latch, and analog circuits respond to the third train of pulses to manifest the frequency of the first pulse train within its predetermined range.

A deflector vane is narrower than the passage and is disposed in the passage in a plane spaced upstream from the slot and generally parallel to said flanges.  The deflector vane includes an inverted U-shaped central channel and flanges extending away from each other from the down stream ends of the U-shaped channel and arranged generally parallel to the flanges defining the slot.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for the protection or preservation of a baled ruminant forage material, such as baled hay which is intended to be utilized as a cattle feed, or the treatment of a soil surface through injection with a liquid preservative and, more particularly, a novel and unique method for the injection of pressurized liquid preservatives such an anhydrous ammonia or proprionic acid, into the baled ruminant forage material or soil.  Moreover, the invention contemplates the provision of a novel apparatus for effecting the injection of the pressured liquid preservative through the intermediary of the inventive method.  When used with a baler, the injection system does not need to cycle with the baler, but injects the liquid preservative into the bale subsequent to the bale having been completely formed, and without the necessity for any reciprocating injector needles or probes having to penetrate into the baled ruminant forage material.  In essence, the inventive apparatus eliminates the need for movable injector needles or probes and, moreover, necessitate the use of only one solenoid so as to simplify the system and enhance the degree of reliability of operation thereof.  Injection valves having discharge orifices or jet-forming nozzles are adapted to be positioned in proximity to the surfaces of and adjacent the path of conveyance of a baled ruminant forage material, or proximate to a soil surface, and in timing with the movement of the baled material or upon sensing the presence thereof, the injection valves are adapted to direct one or more jets of the pressurized liquid preservative against the surface, such as to cause the liquid preservative to penetrate into the bale or soil surface, to vaporize and to disperse within the bale or soil.
