Patent DK-75090-A (DK)
Inventor: SPARKS BRADLEY ALAN
IPC: H03J5/02
Filed: 1990-03-22
Abstract: A receiver comprises a synthesizing tuner circuit (22) for detecting a selected input signal and an audio circuit for reproducing the audio content in the detected signal. The tuner circuit includes a local oscillator (54), a prescaler, a phase locked loop (70) and an integrator (92, 94), and has a tendency to uncontrollably detune during AC power interruption and generate audible noise during the detuning. The audible noise is introduced into the audio content of the detected signal. An AC power interruption detector monitors a run power supply and generates a control signal when the run supply falls below a predetermined threshold. A control circuit (12, 84) responsive to the control signal first disables normal operation of the tuner circuit and then disables the audio circuit, thereby reducing the audible noise. The tuner circuit may be disabled by decoupling the output of the phase locked loop from the input to the integrator, enabling the input to float. In the absence of a corrective signal from the phase locked loop, the integrator maintains a substantially constant output tuning voltage and prevents sudden detuning.

Title: Radio frequency amplifier
IPC: H03J3/06
Filed: 1928-01-03
Abstract: 297,723. Hazeltine Corporation, (Assignees of Walsh, L.). Sept. 26, 1927, [Convention date]. Transformers ; condensers. - In a thermionic amplifier having a tuned transformer coupling system means are provided to vary the inductance of the secondary winding and the mutual inductance between the primary and secondary windings. Fig. 1 shows co-axial cylinders 1, 2 the former carrying primary and neutralizing windings interleaved, and the latter the secondary windings tuned by the condenser 8. 9. Cup like members 6, 7 of copper are mounted on a connecting member 10 together with the movable plates 9 of the tuning condenser, while a flexible plate 11 with the stator plates 8 forms the neutralizing condenser. Fig. 4 shows the mechanism comprising a control knob geared to a toothed quadrant pivoted at 16 and attached to the member 17 and carrying an indicator for controlling a two-stage amplifier. The members 10 are attached to a slidable support, carried by bearings and connected through a link 18 to the control mechanism. Tuning being effected both by inductance and capacity variation, the condensers have a small maximum capacity and the plates may therefor be heavier and more widely spaced. The plates are preferably shaped to obtain a tuning characteristic midway between straightline frequency and straight-line-wavelength variation, while the transformer ratio is so varied as to give a close approach to the maximum permissible amplification within the limit of stability throughout the tuning range. Numerical data of the condenser and transformer design and amplification curves are given in the Specification. Specification 248,311 is referred to.

Filed: 1943-01-07
Abstract: 581,812. Pulse modulation; multiplex signalling. LAWSON, D. I., and PYE, Ltd. Jan. 7, 1943, Nos. 321 and 757. [Class 40 (v)] In a multi-channel pulse signalling system operating on a single carrier frequency, the pulses of each channel are timedisplaced relatively to the pulses of the remaining channels ; and synchronization at the receiver is effected by longer pulses, one for each complete cycle of channels. At the transmitter, Fig. 2, a sine-wave generator 1 operating at about 6 kc./sec. feeds a delay line 2 giving a total delay of about 1/6000 sec. and tappings are taken to a series of pulse generators 3 ... 7. The generator 3 gives a long pulse which serves for synchronisation of the receiver, and the generators 4 ... 7 give short pulses which are controlled as to height, width or phase by modulators for the respective signal channels. The combined output is mixed at 8 and applied to modulate the carrier source 9. At the receiver, Fig. 4, the carrier is rectified and the long synchronizing signals are separated by a discriminator 11 and applied to synchronize a sine-wave generator 12 feeding a similar delay line 13. The signal pulses are applied to a series of gate valves 14 ... 17 which are opened in sequence by voltages derived from tappings on the line 13, and which feed the separate channel receivers 18 ... 21. An alternative receiving arrangement comprises a cathode-ray tube 22, Fig. 5, with a ring of anodes 23 ... 25 across which the beam, modulated by the incoming signal pulses, is swept by deflecting voltages derived from the received synchronizing pulses. The pulses belonging to each channel are taken off from the respective anodes, which may be arranged in circular fashion as shown, or in straight rows (Fig. 6, not shown). Specifications 470,495, 562,211 and 581,811 are referred to.

Title: Method for restarting expert system interruption
Inventor: SHIMIZU NOBUAKI
IPC: G06F9/44
Filed: 1991-01-07
Abstract: PURPOSE:To shorten restarting time at the time of reexecuting an inference after interruption in an expert system which executes diagnoses while imputing interactively symptoms by a user, when the inference is interrupted and restarted by the user's request on a halfway of the inference. CONSTITUTION:The method for restarting processing after the interruption of inference in a diagnostic expert system is constituted of the following stages: a stage to select the only symptoms actually needed for the expert system to execute the inference at the time of the input of the symptoms by using a dictionary 9 by symptoms in which selective methods and working methods for the diagnoses needed for the restart of the inference are stored; a stage to work and degenerate the symptoms by using the dictionary 9 with symptoms when the restarting is available for the inference with the degenerated data alone; a stage to accumulate the selected symptoms or the degenerated symptoms; and a stage to restart the inference by using the accumulated data, at the time of restarting the inference after the interruption of the inference execution process.
