Abstract: FLOW CONTROL METERS FOR GRAVITY FLOW PARTICLE DRYERS            Abstract An improved metering discharge device for parti-culate material, particularly grain, is described.  The device comprises a plurality of tubes extending downwardly from a lower region of a vessel, particularly in uniformly spaced relationship across the bottom of a gravity flow grain drying chamber.  Each tube has an upper end flow connected to the drying chamber and a closed lower end and also has a pair of opposed openings in the side walls.  A rotatable auger extends laterally through the tube via the side wall openings.  The tubes preferably arranged in straight rows with a single auger extending through each row.  This combination of tubes and augers provides a simpler design as well as a more precise flow metering than prior metering rolls.

Abstract: ABSTRACT           A detector for detecting a delta modulated signal includes a timing circuit, a counter and a decoder arranged to detect a delta modulated signal in electrically noisy environment. The timing circuit is used to provide a timing signal of a predetermined time interval over which the counter counts the transition present in the delta modu-lated signal.  The counter is used for counting the digital bit occurrences of the delta modulated signal within the predetermined time interval.  The decoder responds to the timing signal and receives the count signals from the counter signal indicates the number of bit occurrences of the delta modulated signal is above a predetermined high level of count or below a predetermined number of low count and provides a binary signal of a second state when the count signal indicates that the number of the digital bit oc-currances occur between the predetermined low level of count.  The de-tector is further provided with a latch circuit which responds to the output of the decoder and a code detect signal representing detection of a predetermined code signal in delta modulated signal.  The latch circuit is used to provide an output signal in response to the binary signal of the first state from the decoder and the code detect signal to signify proper reception of delta modulated signal.  The above described detector may be advantageously used in a receiver for receiving a scrambled or unscrambled incoming delta modulated digital data signal.

Abstract: Abstract of the Disclosure A hydraulic valve actuator includes at least one piston mounted for reciprocating movement in a cylinder for bidirectionally rotating a valve shaft mounted in the housing.          A resilient spring member is held in compression between one side of the piston and an end wall of the cylinder for yield-ably urging the piston to rotate the shaft in one direction, in the absence of a sufficient opposing hydraulic pressure.         A hydraulic pump driven by an electric motor selectively drives the piston against the force of the spring member for rotating the valve shaft in the opposite direction.  An elec-tric solenoid operated valve is connected with the cylinder at either side of the piston, to provide a selectively open-able path for hydraulic fluid, by-passing the pump to relieve the pressure applied thereby.  Selectively operable mechanical or electronic switches are provided for energizing and deenergizing the solenoid valve and the hydraulic pump to cause the piston to move in the corresponding direction, to open or close the valve as desired.  An electro-mechanical control system is connected with the valve shaft and the switches to actuate and maintain the valve in its fully opened, fully closed, or acme desired intermediate condition.  In one embodiment the electro-mechanical system includes a gear and cam arrangement driven by the valve shaft for actuating mechani-cal switches, and in another embodiment the system includes a potentiometer driven by the valve shaft and an electronic control system responsive thereto for actuating electronic switches.

Abstract: Abstract Keyboard apparatus includes a keyboard having dead-keys which enable accented characters to be entered.  A store preferably read only, is divided into a number of sections, each sections containing character codes representingaccented or non-accented characters associated with that section.  When a dead key is activated, this addresses a section of the store associated with that dead-key to access the address of the section containing the characters with are accented with the accents associated with that dead key:  activation of the next key causes accessing of the accented character code within that sec-tion.  Different accents can be associated with different dead keys.  Option-ally the store can be arranged to store only validly-accented characters, thus avoiding the entry of invalidly-accented characters.  Non-accented char-acters are normally accessed from a single section of the store.  Common accented characters do not require dead-key operation.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a charge transfer device which allows change of the charge transfer direction wherein transfer portions are formed of generally rectangular shape which have a length in the charge transfer direction which gradually gets longer to the transition direction change area and widths which get smaller relative to the direction transverse to the charge transfer direction.  The length times width of the transfer portions is made substantially constant.  The feature providing that the transfer regions become narrower as they approach the portion of charge direction change allows the charge direction change to be relatively shorter than apparatus of the prior art thus resulting in greater efficiency, shorter charge transfer time, eliminates the requirement for direct current bias and a more integrated device is provided.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic safety device having a cable passing through it for stopping a load in the event of a breakdown of a motor drive and/or manual hoist and/or pulling system. The device comprises an automatic cable clamping mechanism having a self-tightening jaw block with two jaws which are constantly urged by a pair of spring driven levers to clamp the cable.          An automatic motor stopping device is also provided and having a circuit breaker coupled with the cable clamping mechanism in such a way that, while the jaw block is not prevented from clamping the cable, the circuit breaker interrupts the motor feed.  An engaging device is adapted to prevent working of the cable clamping mechanism and the motor stopping device as long as the relative speed of the safety apparatus and of the cable is lower than a pre-established critical speed.  An automatic releasing device is actuated by the centrifugal force developing in an inertia block rotated by a driving wheel of a driving device whereby the driving wheel directly or indirectly receives itself a rotary motion from the cable, and which is adapted to neutralize the action of the engaging device as soon as the relative speed of the cable and of the safety apparatus attains the critical speed.  A manual releasing device is adapted to neutralize the action of the engaging device independently from the relative speed of the cable and of the safety apparatus.          The safety device is characterized in that the flanges to which the self-tightening block is linked through its jaw actuating levers are connected with the load directly and/or by means of a case of a hoisting and/or pulling apparatus so that the safety apparatus is adapted to work in order to stop the load either, by a breaking of the cable of the hoisting and/or pulling ap-paratus, on an auxiliary cable, or, by attaining the crticial speed, as well on the cable of the hoisting and/or pulling apparatus as on an auxiliary cable.
