Abstract: Disclosed herein is an improved means for detecting a half-cycle voltage crest of an alternating voltage waveform which includes means for protecting the detecting means from current surges associated with the initial random application of the alternating voltage waveform to the detecting means.

Abstract: A circuit for providing a plurality of distinguishable audible signals from an audible tone generator includes at least two gates wherein the output of one of the gates determines the type of audible signal produced by the audible tone generator in response thereto. The circuit further includes a single control terminal for controlling the logical state the output of the one gate and for controlling the type of audible signal produced by the audible tone generator. The absence of an electrical potential at the control terminal when power is applied to the circuit results in a latching of the output of the one gate and the production of a continuous audible signal by the audible tone generator. The presence of an electrical potential at the control terminal when power is applied to the circuit results in a periodic changing of the output of the one gate and the production of an interrupted audible signal by the audible tone generator.

Abstract: A first rotor is fixedly carried by a shaft and a second rotor is loosely carried by the shaft. A coupling means couples the second rotor to the shaft through flanges extending from the rotor and pinching the shaft. The two rotors are then adjusted with respect to one another by rotating the shaft while holding the second rotor in place.

Abstract: A rotatable shaft for a combination switch and variable resistor is prevented from rotating by a shaft locking mechanism. The locking mechanism includes cooperating grooves and a tab engaging the grooves. The shaft is axially moved to be put in a rotatable position.

Abstract: An audible signalling system utilizes a piezoelectric transducer to produce a chime tone audible signal. The system includes audible signalling circuitry, circuitry for driving the audible signalling circuitry to provide a pulsed audible signal, and circuitry for exponentially decaying the pulsed audible signal to produce a chime tone audible signal.

Abstract: Disclosed is a control system for controlling the operation of an appliance and the like which is particularly adaptable for controlling at least one operation variable of an apparatus for drying articles such as a clothes dryer, washer-dryer or similar type of appliance. The drying apparatus is capable of accurately drying any number of articles to a desired degree of dryness irrespective of time by sensing a plurality of temperatures and deriving a final temperature difference for each load of articles indicative of the degree of dryness desired. Furthermore, the control system provides the ability to optionally control the drying apparatus by timing its operation, to control the temperature of the air used for drying, to reduce the temperature of the air used for drying before the completion of an operation cycle so as to avoid setting wrinkles, and to determine and indicate when excessive lint has accumulated on the lint filter.

Abstract: A pair of electrical terminals are held in close spaced relation to each other to provide a gap therebetween. A third electrical terminal extends into the gap. A spring contact arm engages the third electrical terminal and pivots between it and the other two electrical terminals.

Abstract: A three membered capacitor sealing structure is disclosed including a lower vinyl thermoplastic layer, a layer of natural or synthetic rubber, and an upper layer for rigidity. The layers may contain vents, openings, and/or piercings.

Abstract: A push button has successive adjacent stations to receive push rods of switches, the first station being disposed a predetermined distance from the button case, the next two stations being disposed at distances which are at predetermined ratios based on the location of the first station.

Abstract: An electrical device is provided with a compressible intermediate layer between an active electrical component and an exterior protective coating. The intermediate layer includes a substantially solid filler material in a resin binder material. The compressive intermediate layer helps to protect a fragile electrical component from stresses resulting from possible shrinkage of the protective coating during curing or hardening, from expansion or contraction of the protective coating during temperature cycling and from the adhesive nature of the protective coating.

Abstract: The disclosure relates to an electrical component with low impedance over a range of high frequency input signals. The electrical component comprises a body including a metal anode with a plurality of anode risers contacting the anode, each of the anode risers extend from the anode a relatively short distance with a minimum of spacing therebetween. Anode and cathode levels extend from the body a relatively short distance in spaced substantially parallel relationship with each other. Preferably, the lengths of the anode and the cathode leads are a minimum as well as is the distance between each of the leads in order to further help reduce the impedance of the electrical component over a range of high frequency input signals.

Abstract: Bearing surfaces are provided for a shaft and a rotor carried by the shaft as both are rotated against the base of a cup shaped member which forms part of the housing for a variable resistance control.
