Abstract: The receiver comprises a processor circuit which receives and processes a modulated carrier wave. The modulation is a code consisting of a single tone or a sequence of tones, followed by intelligence signals. The processor circuit separates the code and the intelligence signals from the carrier wave. The receiver also comprises a decoder circuit responsive to a given code to provide an enabling signal. An audio circuit is rendered operative by the enabling signal so that it can process the ensuing intelligence signals. The receiver has a push-button switch which can be actuated at any time to monitor the channel. Such switch is associated with a timer and an electronic switch.A first optional connection may be made internally in the receiver, whereby actuations of the push-button switch places the receiver in a monitor mode so that it will be continuously on. Subsequent actuation of the switch will cause the receiver to revert to its tone-squelch mode.

Abstract: A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath, the container being separated by a partition into a lower soap reservoir and an upper refill compartment, the latter adapted to enclose therein a removable refill cartridge and having a downwardly extending refill well with a pair of opposed keys extending thereinto. The cartridge has an outlet neck, the outer surface of which has a pair of opposed slots. The neck is closed by a pierceable membrane recessed therein and adapted to be received into the well so that a cartridge opening member pierces the membrane to accommodate free flow of liquid soap from the cartridge to the reservoir. The cartridge is entirely closed to define the liquid level in the reservoir at the bottom of the neck, and a drain hole in the reservoir wall above the bottom of the neck but below the tops of the keys prevents bootleg cartridges from being used in the soap dispenser.

Abstract: The filter has a fixed Q and is coupled to a source of AC signals. A source of pulses is applied to a variable-voltage circuit, the circuit being responsive to each pulse to produce a threshold voltage which varies from a first value toward a second value. A comparator circuit has one input coupled to the filter and a second input coupled to the variable voltage circuit. The comparator produces a signal for a duration related to the time the amplitude of an AC signal from the filter is at least equal to the threshold voltage.

Abstract: A vibratory electric motor and appliance embodying same contemplates a pair of shallow pan members which are reversely secured together by means of peripheral portions thereof. The pan members have spaced and aligned generally parallel portions within the peripheral portions which cooperate to mount the vibratory motor. The latter is more or less conventional except that the armature leg which is spaced by a gap from the pole faces of the core-coil assembly has an enlarged width about equal to the spacing between the parallel portions of the pan members. Each side of this widened armature leg has a pair of spaced projections which respectively enter apertures in the parallel portions of the pan members. Thus, when the pan members are secured together at the peripheral portions thereof, the motor is firmly mounted in engagement with both pan members, thereby avoiding auxiliary mounting parts and the assembly time required to install such parts.

Abstract: The signal absence detector controls an operator circuit which periodically provides an operator signal to render the processor circuit in a communication receiver operative. The absence detector responds to a processed signal which is not of a predetermined character to terminate the operator signal. In one form of the invention, the operator circuit is a battery saver which intermittently provides a supply voltage. When the incoming signal is of the predetermined character, the supply voltage continues. The absence detector terminates the supply voltage when it is determined that the incoming signal does not have that character. In another form of the invention, the absence detector is employed in a scanning receiver, in which case the operator circuit steps the receiver between the various channels. The receiver will remain tuned to a channel as long as the incoming signal may be of the predetermined character.
