Abstract: ABSTRACT This invention relates to a novel process for preparing a shaped starchy foodstuff which is preferably fried.  This is accomplished by hydrating a dry starchy foodstuff base where an effective amount of a raw or pre-gelatinized modified tapioca starch is added to bind the starchy foodstuff.  Then the hydrated starchy foodstuff with tapioca starch is shaped.   When frying is the next desired step the shaped starchy foodstuff is placed in the fryer while the food-stuff is as cool as practical, without being frozen, to minimize weight loss and oil pickup.           Subsequent to either the frying or shaping step the starchy foodstuff is preferably frozen.

Abstract: ABSTRACT OF THE DISCLOSURE Monitor position of winding flyer in relation to a machine frame, substantially continuously generate signals indicative of flyer position and control relative jump of coil forms and flyer in response to signals.  Jump is initiated during a predetermined portion of a flyer revolution while flyer is in "jump window" relative to turn receiver.  Energy stored in lost motion mechanism contributes to acceleration of jump mechanism; and same mechanism adsorbs and stores energy as moving structure stops.  Parts of coil forms are adjusted substantially equal distances relative to a geometric center and turn receiver and winding head undergo relative movement to maintain mutually aligned relationships.  Fast and consistently responsive latch mechanism insure jump during fraction of flyer revolution in different machine cycles. Jump mechanism urged against latches by pre-loaded spring mechanism for increased acceleration and to absorb prime mover force at end of jump stroke.  Fast response diaphragm piston operated latch mechanisms permit initiation of jump stroke.       Means adjust coil form parts in opposite directions while form parts remain centered relative to flyer axis. Device maintains desired alignment of at least one coil form part and winding turn receiver.  Screw with spaced apart right-hand and left-hand threads move coil form parts relative to one another.

Abstract: ABSTRACT OF THE DISCLOSURE A generating system employing a generator having a self-excited field winding the excitation of which is achieved by supplying a bridge circuit with signals which are, respectively, proportional to the generator terminal voltage and the load current further includes means to selectively short-circuit  the field winding during each cycle of normal generator operation. The system further includes a feedback path or loop for controlling the time during which the field winding is short-circuited which feedback path develops a control signal by comparing a signal representing the voltage supplied to the bridge circuit with a reference signal to develop an error signal which is then modified by a further signal proportional to the Thevenin equivalent voltage of the bridge circuit to thus linearize the feedback loop.

Abstract: WEIGHING SCALE HAVING COMMON SEQUENTIAL DISPLAY OF WEIGHT, PRICE PER UNIT WEIGHT, AND TOTAL PRICE, WITH AUTOMATIC DISPLAY SEQUENCING UPON WEIGHT CHANGE              Abstract of the Disclosure A computing weighing scale has a display including single multi-digit numerical indicator driven in real time by the scale microcomputer to show, sequentially, weight of the article, price per unit weight, and total price or value of the article, and also includes function words identifying the nature of information shown to the scale operator and customer.          The scale also includes weight code generating mechanism, a keyboard for entering numerical information, and the micro-computer.  The indicator can also display tare weight, entered via the keyboard when no weight is on the platter.  If tare is entered and subsequent weight on the platter is less than entered tare, calculating is inhibited.  If platter motion is detected with weight on the platter, the display will reset to the weight indicating condition and automatically sequence to show again price per unit weight (if entered) and total price.          When all weight is removed from the platter, entered tare is erased.  Price per unit weight can be entered via the keyboard only when there is some minimum weight on the platter and is remembered for recalculation if weight on the platter is changed but not removed.  Price per unit weight is cancelled when all weight is removed from the platter.     Keyboard switches are interrogated a plurality times before entered information is accepted, to assure the key entry is valid and switch contact bounce has terminated.  The platter motion detector is disabled for a short time after a key actuation, to avoid system resetting as a result of platter movement which may be induced by keyboard actuation.          The microcomputer scans the possible inputs from the scale and the keyboard, and sends output signal to the display, at real time rates which are compatible both with human keyboard manipulation and retention.          Scale operation is divided into two portions which are called the communicate and compute cycles; the communicate cycle is usually repeated many times between compute cycles in order that real time information sensing and display operation be possible.

Abstract: RECORDER TRANSFER ARRANGEMENT MAINTAINING BILLING DATA CONTINUITY     Abstract of the Disclosure Redundant but independently operable data processors called encoders are arranged so that control of a particular recorder gathering billing data in a telephone switching sys-tem can be transferred while maintaining billing continuity for calls being handled by that recorder.  More specifically, each encoder checks the validity of billing information re-ceived from each recorder.  However, each encoder only trans-mits billing data pertaining to a designated group of recor-ders to a remote processor.  When an encoder detects that it is not receiving valid data from one of its designated recor-ders, the control of only that designated recorder is trans-ferred to the other encoder if the other encoder indicates that it is receiving valid data from that recorder.  More-over, the relinquishing encoder sends a message to the remote processor indicating that it is giving up control of the de-signated recorder, while the accepting encoder inhibits the transmission of information to the remote processor for a predetermined time interval and then transmits a message in-dicating that it has accepted control of the designated recor-der.  This delay ensures that the remote processor will receive the relinquish message before the acceptance message so that the continuity of processing billing data for calls handled by the designated recorder can be maintained.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic plug changer is disclosed, particularly for a plug mill, although some features may have applicability in con-junction with related mills, such as piercing and reeling mills. A rotatable drum is mounted below the pass line of the mill and has pockets for containing a plurality of mandrel plugs.  A com-bined plug support and discharge trough is movably positioned between the plug-containing drum and the mill rolls, and is aligned with a plug-receiving position in the drum.  After a tubular shell has been driven through the mill, over a mandrel plug, the plug simply drops out of the mill, slides down the discharge trough and is received in the drum.  The drum then indexes to a new position, bringing a new plug into alignment with the trough.  A pusher mechanism then moves the plug out of the drum and onto the discharge trough.  The trough is then pivoted upwardly and becomes part of the inlet trough for the tube shell, positioned to be passed through the mill, serving to support the plug until it is picked up by the incoming tube shell.  The new mechanism improves the overall ef-ficiency of the plug mill by substantially reducing the time re-quired for the plug change cycle to occur.

Abstract: SIGNAL REPEATER FOR POWER DISTRIBUTION      LINE COMMUNICATION SYSTEMS               ABSTRACT OF THE DISCLOSURE A half-duplex communication repeater for use with power distribution lines.  The repeater includes two re-ceivers, two signal generators, a single power amplifier, and a control circuit.  The control circuit coordinates the operation of the receivers and the signal generators and prevents the application of the signals from both generators simultaneously to the signal amplifier.  The outputs of the two signal generators are applied to transmission gates which are both coupled to the signal amplifier.  When an appropriate signal is detected by one receiver, it produces an output signal which is coupled to a latching circuit, The latching circuit turns on the appropriate transmission gate to pass the signal from the corresponding signal gener-ator to the signal amplifier.  Due to the operation of the latching circuit, a signal detected simultaneously by the other receiver will not cause the other transmission gate to turn on and apply two signals simultaneously to the signal amplifier.  A third transmission gate may be coupled to the common output connections of the other two transmission gates for providing a load on the gate devices to reduce the signal transfer through the gate devices when they are in the tunred-off condition.

Abstract: ABSTRACT:             A digital filter and demodulation arrange-ment for passband signals, whose corresponding baseband signal has a bandwidth limited to a given maximum fre-quency.  The passband signals are filtered according to two bandpass characteristics which, apart from their asymmetrical distortion relative to their central fre-quency, are versions from one another shifted 90° in phase.  The filtered passband signals are demodulated with an in-phase carrier and a quadrature carrier and the demodulated signals are combined to a baseband signal.  In the digital filtering process the sampling frequency is reduced from a value higher than twice the highest frequency in the passband signals to a value which is not higher than twice said maximum frequency in the baseband signal and in the digital demodulation and combination processes the reduced sampling frequency is also used so that a considerable reduction in the inter-nal processing speed is obtained.
