Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to a reference signal circuit in a multi-frequency signal receiver in order to obtain a detection of the two signalling frequencies in an incoming voice frequency signal independently of disturbing signals of certain duration.  The circuit contains two paths for receiving the incoming signal. One path includes rectifier and attenuation means to give a first signal level dependent on the incoming signal level.  The other path includes first comparator means to compare the momentary level of the incoming signal with said first signal level, a time circuit and a second comparator means in order to obtain a second signal level whose magnitude is dependent on the duration of the incoming signal.  The outputs of the two signal paths are connected together via a gating circuit to give a reference  voltage to analog signal comparators included in the multi-frequency signal receiver.

Abstract: ABSTRACT      A control system used to change the gear ratio in a gear set regulated by a change-gear signal from a control unit is disclosed.  A transducer provides an output torque signal which is compared to other signals for initiating the gear change.    In another arrangement, an automatic transmission changes a gear ratio when engine torque is transferred from one member to another member of a three member planetary gear set.  This transfer is accomplished through friction elements engaged by hydraulic pressure.  A closed loop electrical circuit is completed between a transducer, which provides an electrical signal related to the output torque of the transmission, and a control valve, to vary the control valve pressure.  A circuit for computing reaction torque is coupled between the transducer and a logic control circuit, which provides logic command signals for controlling operation of components in the closed loop circuit.  The closed loop circuit includes a pulse width modulation circuit for regu-lating the control valve operation, and a feed-forward circuit to minimize the delay in the control valve portion of the system.

Title: Alignment control system particularly suited to control traveling irrigation systems
Inventor: SAGE DOUGLAS E
IPC: A01G25/09
Filed: 1977-03-09
Granted: 1981-01-20
Abstract: ABSTRACT OF THE DISCLOSURE An electrical strain gauge is mounted to respond to movements between two sections of a structure. The gauge is mounted on a surface that deforms in response to mis-alignment of the sections in a selected plane. The mis-alignment or the deflection is detected electronically utilizing the strain gauge and the degree of deformation, mis-alignment, or flexure is monitored. Upon reaching selected magnitudes in either direction, signals are generated which may be used to control the amount of deflection. When utilized to control the alignment of sections of a traveling irrigation system, the strain gauge is attached to a bar between adjacent sections which bar flexes upon mis-alignment of sections in the horizontal plane. A pair of electrical sensors monitor the deflection but only one is permitted to generate a signal. A switching circuit selects the appropriate signal generator depending on the direction of travel of the equipment.  One such circuit determines the phase sequence of the three phase AC power which sequence may be varied to change the direction of the system travel. The circuit converts the signals from two of the AC phases into two series of pulses. The existence or non-existance of overlap between the individual pulses of the two series is dependent and indicative of the phase relationship and used to trigger a flip-flop. This phase detector may be used apart from the alignment control system. The signal starts or stops a drive motor on one of the sections to re-align the sections. A pair of monitors act as a safety interlock to shut down the system if the deflection is excessive in either direction.     .

Abstract: COMPUTER ASSISTED TEACHING ARRANGEMENT      FOR CONVEYOR LINE OPERATION                 Abstract of the Disclosure A programmable manipulator having an arm which is movable in a plurality of axes and encoder apparatus for the axes operative to develop position signals corresponding to the actual position of the arm is provided adjacent a workpiece moving along a predetermined path, a conveyor for example, to perform a series of programmed operations on the workpiece.         The programmable manipulator is provided with teach-programming apparatus for moving the arm during an initial teaching operation to different positions of the stationary workpiece corresponding to the desired series of operations of the manipulator relative to the stationary workpiece.  Further, apparatus is provided for calculating digital representations during the teaching operation representing the positions of the arm accounting for the projected workpiece movement and corresponding to the initial teaching positions relative to the workpiece.  The programmable manipulator then stores the calculated digital representations for use in controlling movement of the arm during playback with a moving workpiece.         The manipulator control electronics is provided with a variable duration interpolation period unit which is effective to maintain the manipulator in synchronism with the conveyor and to achieve substantially constant velocity in a continuous path mode over the program steps by dividing the recorded conveyor  positional signals for successive steps into a predetermined number of increments and utilizing the interpolated increments as artificial command signals.         A velocity mode constant is also calculated and recorded during the teach mode and utilized in playback to generate velocity command signals to control the manipulator.                             -ii-

Abstract: HARDWARE CONTROL STORAGE AREA PROTECTION             METHOD AND MEANS                            ABSTRACT      The embodiment provides a bit position in a system control register (CR) which is set to enable, and is reset to disable, the HCA protect means.  An AND gate has an input which receives the enablement or disablement signal from the control register HCA protect bit position. The AND gate also receives the store requests from the processor, and further receives a signal common to all addresses in the HCA area such as all zeros for address bits 8 through 22 to signal the first 512 bytes in main storage which in current IBM S/370 machines contains the HCA, which is also called the program save area (PSA). The AND gate is normally disabled by the CR bit and provide and inverted output to a store request gate which normally provides store requests to the processor store access controls.  Writing into the HCA is only permitted under special programmed conditions when the control register bit is set to disable the HCA protect means.  Whenever the HCA protection is enabled, the AND gate is enabled to provide an HCA store violation signal, which actuates a protection interrupt code generator to generate a storage protect interrupt code in the PSW (Program Status Word) that causes the processor to test each store request into the HCA.  The CR protect bit is disabled before and enabled after each legitimate HCA change code in a system control program to form a window in the code.

Abstract: ABSTRACT:          Prerecorded video discs will generally be provided with a programme which has originally been recorded on film,which programme is transformed into a television signal by scanning the film frames. Owing to the difference between the standards for film and television employed in the United States consecutive film frames always result in sets of un-equal numbers of fields on the record carrier. Pre-ferably an indication signal is added to each set of fields on the record carrier. The read apparatus comprises detection means for detecting said indi-cation signal.  This signal is used to ensure that in the still  picture mode, during which the same two fields on a track circumference of the record carrier are repeatedly read, two fields are read which belong to the same set and consequently stem from the same film frame,
