    摘要: A color converter circuit particularly suited for use with computer-steered multi-color display units accepts at its input terminals a plurality of color commands from the associated computer or other signal source, and includes manual selection means for selecting a corresponding plurality of different output color commands to be actuated selectively upon response of each different input color command to provide manual control of the colors of the generated pattern, without requiring software modification. Associated indicator lights adjacent each of the color-selecting switches indicate which colors in the form of color commands are being sent from the computer. A simplified version of the converter accepts monochrome commands capable of giving only dark and bright commands from the computer, and selectively provides optionally chosen different color commands to the display unit to correspond to each of the two input signal conditions.

    摘要: A surge protection circuit for insertion into a coaxial cable system is configured as a coaxial structure of given characteristic impedance extending between matching input and output connection. A surge suppression network is built into the coaxial housing, and includes a shunt inductor shunting the center conductor at an intermediate point to the housing. A capacity is series-inserted into the output section of the center conductor beyond the inductor. The capacitor is a plate-shaped element metalized on both faces and edge-inserted into the confronting line sections of the center conductor and soldered thereto, so that capacitor lead inductance is incorporated into the center conductor. At the passband frequency of cable television communications the reactance of the inductor is high compared to the characteristic impedance, and similarly the reactnace of the capacitor is low, resulting in negligible insertion loss to the system. At the uppermost harmonic component frequency of line surges the low inductive reactance, and the high capactivie reactance cause strong attenuation of surge signals. A pair of diodes connected between the output sections of the center conductor of the coaxial line and the coaxial housing or outer conductor provides additional surge attenuation.

    摘要: A manually operable pulse generating apparatus comprises a dial knob assembly having a outer grippable knob member rotatably mounted around an inner knob member connected to an operating shaft carrying a ratchet wheel-forming cam having saw-toothed ratchet teeth-forming lobes. Each lobe has a gradually rising leading side and a sharply dropping trailing side. The outer knob member is connected to the inner knob member through a one-way clutch so that the outer knob member can be rotated in one direction without rotating the inner knob member, the inner knob member rotating with the outer knob member when rotated in the opposite direction. Where the outer knob member is opaque, it contains numbered markings for identifying the degree of rotation imparted thereto relative to a stationary index mark on a control panel over which the dial knob assembly is mounted. For some applications, the outer knob member may be transparent in which case the numbered markings referred to are on the inner knob member. A pawl-forming, force-transmitting spring or spring-urged member normally rests in the crotch between successive ratchet teeth-forming lobes of the cam where it is in a partially tensed condition to form a detent for the shaft. The rotation of the outer knob member in said other direction rotates the cam and causes the pawl to ride up the gradually rising side of a cam lobe so that the tension in the pawl initially slowly increases. The tension on the spring or spring-urged member is coupled to a piezo-electric element which generates a damped sine waveform as the tension thereon is suddenly relieved as the end of the pawl falls into the crotch between a pair of cam lobes.

    摘要: A timer system includes a power switch operable to power circuit closing and opening conditions, timing means for identifying various timing segments over a 24-hour period and marker storage means having respective power turn on and off marker storage locations assigned to the time intervals encompassing a 24-hour period. An on-off push button or other on-off control operates the power switch and may act as an aid in setting the markers in the storage means. The timer system may also include a rotatable present time setting dial, also adjustable to different positions representing the different time intervals, and a manually operable timer on-off setting member. For real time programming, control means respond to normal operation of the on-off control during a first 24-hour period, initially to set said markers in the storage locations. For fast programming, the control means responds to the successive advancement of said dial from a present time setting through said various positions and the selective operation of the push button or other on-off control to set the markers in the storage locations assigned to the time interval involved, which markers automatically control the operation of the power switch when the timer on-off setting member is in its timer-on position, except when overriden by operation of the on-off control.

    摘要: A stereo headphone employing a standard stereo headphone plug is adapted for automatically hearing a monaural signal at both earpieces, when accessing a typical monaural source. In the first embodiment of the invention, an impedance element couples the signal from a first acoustical driver that receives the monaural signal from the stereo plug tip, to a second acoustical driver that is connected to the stereo plug ring and normally receives no signal when plugged into a conventional monaural audio source output jack. The magnitude of the coupling impedance is selected with respect to the impedance of the acoustical driver so that the reduction in loudness at the second earpiece due to the signal voltage drop across the coupling impedance is not perceptible to the listener. This will occur when the reduction in loudness at the second earpiece is less than the threshold of perceivable loudness reduction at one ear when there is no reduction in loudness at the other ear. The effect of the coupling impedance, when listening to a stereo audio source is insignificant, firstly, because the two stereo channel signals appear at their respective drivers with virtually no attenuation due to the coupling impedance. Secondly, although the coupling impedance does contribute a slight amount of additional crosstalk between the stereo channels, the magnitude of the increase in crosstalk is dependent upon the ratio of the coupling impedance to the output impedance of the stereo source. A typical stereo source for which the use of this headphone is intended has an output impedance so low compared to the coupling impedance that the increase in crosstalk is too small to be perceptible as affecting the stereo separation or the stereo imaging afforded by the stereo source. In the second embodiment of the invention two equal impedance elements couple the monaural signal from the stereo plug tip to each acoustical driver. This equalizes the loudness of the monaural signal heard at each earpiece and slightly reduces the level of one stereo channel with respect to the other. Crosstalk and stereo imaging are virtually unaffected, as with the first embodiment.

    摘要: One form of the timer is designed to be mounted over and behind a conventional wall switch cover plate and includes a two position timer condition-setting arm, a rotatable and depressible time setting dial knob and an indicator on the front of the cover plate. When the arm is moved to a timer-on position, the indicator flashes to indicate that timer programming is needed. This may be achieved in real time over the first twenty-four hours after a 30 minute play period by depressing the knob acting as an on and off power switch control push button to turn the light circuit on and off in a normal manner. Fast normal programming is achieved by rotating the knob to various time settings and depressing the knob to set ON or OFF markers in timer memory. A full twenty-four hour programming is completed by either completing a full rotation of the knob over the full twenty-four hour time settings, with at least one ON and one OFF depression, or by a similar pair of knob depressions without such a full rotation, OFF markers then being automatically set by the timer to complete the timer programming. The indicator comes steady-on to indicate that the timer is fully programmed and in an automatic mode of operation. The automatic operation is temporarily overridden by depression of the knob or permanently overridden by a simple distinctive speed or time duration depression of the knob.
