Abstract: TELEPHONE LINE CIRCUIT WITH DIFFERENTIAL LOOP      CURRENT SENSING AND COMPENSATION            Abstract of the Disclosure The invention provides a telephone line circuit in which the likelihood of exposing circuit devices in an associated switching facility to potentially damaging currents or voltages is greatly reduced.  A repeat coil includes a primary winding for connection to a subscriber loop circuit.  Direct loop current is maintained in the primary winding and the resulting d-c flux is compensated for by a regulator including a balancing winding.  The core material in the repeat coil is saturable and limited in bulk to that sufficient to transmit normal a-c voice signals across the line circuit.  Signals of a magnitude which cause the core material to saturate are thereby impeded in transmission across the line circuit.                     - i -

Abstract: APPARATUS FOR FILLING AND CROWNING BOTTLES     Abstract of the Disclosure An apparatus for filling and closing containers, such as bottles.  The apparatus includes a rotary filling machine for moving each bottle in a circular path of travel and filling the bottle with liquid.  The bottles are crowned by a rotating crowner which is located adjacent the filling machine and the crowner moves each bottle in  a circular path of travel and applies the crown to the filled bottle to close the bottle.  An endless chain transfer conveyor having a plurality of pockets to receive the bottle serves to transfer the bottles from the filling machine to the crowner and from the crowner to a discharge conveyor.  The chain is driven by a sprocket mounted on the crowner and the chain moves tangentially to the circular path of travel of the filling machine, so that the bottles are transferred from the filling machine to the pockets on the chain conveyor.  After crowning, the bottles are transferred from the pockets in the chain to the discharge conveyor by a stripper member.  As the filled, uncrowned bottles moving from the filling machine to the crowner move in a straight path of travel they are not subjected to centrifugal force and thereby liquid loss and air entrapment are minimized.

Abstract: ABSTRACT OF THE DISCLOSURE                An inrush current restraint circuit, for use with a typical overcurrent minimum pickup circuit of a power system switching device, such as a recloser or sectionalizer, for raising the initial overcurrent minimum pickup value upon closure of the switching device to a selected value, then linearly returning this pickup value to normal within a selected period of time.  The minimum pickup circuit is actuated by the voltage drop across a current sensing resistor, through which a current signal proportional to current in the power system is passed.  The initial pickup overcurrent value is increased by providing another current path in parallel with current sensing resistor when the switching device is closed.  A timing capacitor is discharged each time the switching device is open, then charged from a constant current source each time the switching device is closed.  The voltage across this timing capacitor is applied to the input of an amplifier having a unity voltage gain and the output of this amplifier is connected in series with a second resistor across the current sensing resistor.  When the timing capacitor is charged to a voltage higher than the voltage produced across the current sensing resistor, the amplifier is back biased to effectively open the additional current path through the second resistor, and return the minimum pickup current to its normal value.

Abstract: DIGITAL SPEEDOMETER FOR INDICATING VELOCITY IN AT     LEAST TWO SELECTABLE UNITS OF MEASUREMENT              ABSTRACT OF THE DISCLOSURE     A digital speedometer for indicating angular or linear velocity has an index counter to control update of the displayed velocity.  The purpose of the index coun-ter is to prevent undesirable fluctuation of the displayed velocity where minor variations in velocity being measured have occurred.  The digital speedometer uses a pulsating input signal having a frequency proportional to the velocity to be indicated.  An oscillator circuit provides a clock frequency that is utilized in generating a counting period electrical signal.  During the counting period, the input pulses proportional to velocity are gated into a counter.  After each counting period, a comparison is made between the count currently being displayed and the count stored in the counter.  If a difference occurs, the index counter is incremented.  Only after the index counter has been incremented a plurality of consecutive times is the display permitted to be updated.

Abstract: Title of the Invention DISTRIBUTED MULTIPROCESSOR COMMUNICATION SYSTEM          Abstract of the Disclosure A distributed multiprocessor communication system, wherein the central processing unit (CPU) is relieved of the burden of bus management by a scheme which multiplexes the interprocessor module communications bus, to which all pro-cessors are guaranteed access, so that only an addressed CPU may be interrupted from performing its dedicated data processing function.  Associated with each independent processor is a communications interface unit or communications network routing unit which relieves the processor of the task of decoding communications on the interprocessor or intermodule communica-tions bus and, in addition, upon decoding its address and buffering message data, transmits a "handshake" signal over the bus back to the sender during a designated time slot, thereby informing the sender that the transmitted message was actually received.  Moreover, if one module is in a high priority mode of communication with another module, all lower priority messages are prevented from entering that particular module; yet, any other pairs of modules may still communicate.  In other words, no module can possibly tie up the bus, preventing other modules from communicating.          Once the data is placed onto the bus, under CPU direction, the transmission, reception, priority discrimination, and handshake are completely independent of CPU operation so that the time required to transfer a byte of data is independent of any processor in the system.

Abstract: ABSTRACT:            An apparatus for detecting deviant grain direction in timber by means of high frequency radio energy like microwave radiation. According to the invention the deviant grain direction in timber, especially in sawn timber can be detected so that knots cause no significant error to the measuring result. The knots are detected by the apparatus according to the invention in so far as they contains the deviation of wood grain. The microwave radiation is let to pass or reflect from the piece timber (1). Radiation is transmitted by a transmitting antenna (3) with a certain direction of polarisation and is received by a receiving antenna whose direction of polarisation forms an angle of 90° with the direction of polarisation of transmitting antenna. According to a preferred embodiment of the invention the polarisation of transmitting field is changed so that it alternatively is parallel or perpendicular to the direction of polarisation of receiving antenna. The signal of deviant grain direction is measured when both polarisation planes are perpendicular to each other and the reference signal is measured when the said polarisation planes are parallel.
