Title: Improvements relating to devices for indicating, relaying, or recording the difference in frequency of two alternating electric currents
IPC: G01R23/02
Filed: 1933-01-05
Abstract: 412,953. Measuring frequency. LAWES, W. H., 5, Hornby Road, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 5, 1933, No. 428. [Class 37.] A device for indicating, recording, or relaying the difference in frequency of two alternating currents comprises two rotary shafts, one of which is rotated at a speed corresponding to the standard frequency and the other of which is rotated by an electric motor, the speed of which is dependent upon the other frequency, which shafts are arranged to exert torques in opposite directions on a third shaft which is provided with restraining means opposing its movement from a zero or neutral position. As shown in the Figure, the motors 1, 5 rotatable at speeds corresponding to the standard and the other frequency respectively have their shafts 2, 6 arranged to rotate pairs of permanent magnets 3, 4 and 7, 8 so as to produce opposing torques by inductive action on a conducting disc 10 carried by a third shaft 9. When the two frequencies are equal these torques are equal and opposite so that the pointer 12 carried by the shaft 9 is held by a spring 11 in a neutral position, but as the measured frequency varies from the standard the corresponding variation in the opposing torque causes the movement of the pointer in one or other direction. In an alternative arrangement the two motors may drive fans to produce currents of air acting in opposite directions on a vane or vanes or different sets of vanes attached to a third shaft so as to produce an indication of any departure from the standard frequency. The third shaft may be arranged to operate relay contacts and may be employed in a frequency control system. For calibration purposes one of the motors may be arranged to be adjustable on its base.

Title: Improvements in or relating to the recording of radar signals
IPC: G01S7/04
Filed: 1955-01-11
Abstract: 781,886. Radar. JONES, A. L. PHIPPS-. Jan. 11, 1956 [Jan. 11, 1955], No. 822/55. Class 40 (7). Radar signals are recorded by being impressed on a recording medium in conjunction with a series of pulses representing the instantaneous angular positioning of the scanner. In an embodiment using photographic recording medium a rotating radar scanner is associated with a transmitter 11 and receiver 12 and the echo signals from the receiver are mixed at 13 with a synchronizing pulse or identification group of pulses, and a series of pulses representing the angular position of the scanner. The composite pulse train thus formed is used to intensity-modulate a suitably timed linear scan on the screen 17 of cathode-ray tube 14. The linear trace is focused to form a transverse line on the film 18 in camera 19. The film is driven through the camera by motor 21 at a relatively low speed such that the distance between images of successive traces is somewhat less than the minimum resolution of the emulsion used. The resulting record may then appear as shown in Fig. 3 where a<SP>1</SP> is the line resulting from the insertion of a synchronizing pulse at a point early in each scan, b<SP>1</SP> and b<SP>11</SP> are radar echo indications and c<SP>1</SP> and c<SP>11</SP> are curves representing the sine and cosine of the scanner angular position. These latter result from the merging into a continuous curve of appropriately placed pulses at the end of each trace on the tube 14. The series of indications b<SP>1</SP> correspond to the responses in each aerial scan from a fixed object whilst those shown as b<SP>11</SP> correspond to those from a moving object. Instead of displaying the information on cathode-ray tube 14 and photographing the trace the composite signal from the mixer may be fed directly to a magnetic recording head so that the information may be recorded on magnetic tape. If a record of moving objects only is required a record may be made on an endless band of magnetic tape at a time when no moving objects are present, and signals synchronously picked-off the tape fed to a mixer in opposition to currently received signals in order to produce a resultant output free from indications of permanent objects. This output may be recorded photographically or magnetically, as described above (Fig. 6, not shown).

Title: Design back-up device for operation control panel
Inventor: TAKIZAWA YOJI
IPC: G06F17/50
Filed: 1986-01-07
Abstract: PURPOSE:To effectively design an operation control panel which excels in the operability by using a simulator that simulates the plant operation at a higher speed than the real time. CONSTITUTION:For instance, the abnormality occurs at a plant and the plant is scrummed. Thus the line of flow of an operator is evaluated. In such a case, the disturbance is given to a simulator 3. Based on the operating state of the plant, an operating guide system 5 decides the optimum operation confirming procedure and outputs the operation request signal 11 to the simulator 3. Then the simulator 3 continues the operation based on the signals 11 delivered successively according to the operating state of the simulator 3. At the same time, the operation confirming procedure and the plant operating states are outputted to a production system 7 for the line of flow of the operator from the system 5 in the form of a list. Thus it is possible to produce the line of flow of the operator with high efficiency and design an operation control panel which excels in the operability.
