Abstract: Abstract of the Disclosure Subscriber access to the television transmissions of a cable TV system or other wired program transmission is governed by switching means in the remotely controlled unit to which the subscriber's receiver is connected, which switching means is enabled or disabled in response to information coded on the power flow which energizes the controlled unit.  The power to the con-trolled unit may be coded at the cable TV power supply in response to a separate modulated RF carrier signal transmitted to all power supply units from the cable television broadcast central station, or other central location.  Stated in other words, a program control  center generates binary coded instructions in-cluding address words which are conveyed in a wired signal trans-mission system to multiple subscriber stations by modulating in a special way the frequency of a power supply used to supply energization to portions of the system.  Upon comparison of the addresses, each station addressed is directed remotely by the coded instructions to achieve any of a plurality of switching functions, including the selective connection of program materials to the subscriber's outlet.

Abstract: ABSTRACT OF THE DISCLOSURE       For an analysis of the sound source of speech, a fre-quency spectrum analysis is previously effected and the speech wave is applied to a circuit having a characteristic inverse to the frequency spectrum to make the frequency spectrum substantially flat and a residual value composed of an impulse train of the sound source or a noise is picked up and analyzed, whereby a sound source signal is extracted.   For an economical construction of such a speech analyzer, unneces-sary high frequency components contained in the residual value are cut off by a low-pass filter to enable low-bits quantiza-tion of the residual value and the correlation coefficient of the residual value is utilized to thereby enable a speech fundamental period extractor to be, formed with low-speed elements.

Abstract: BIDIRECTIONAL VOICE FREQUENCY REPEATER     Abstract of the Disclosure Hybridless bidirectional transmission networks typically include telephone line coupling transformers and unidirectional amplifiers for enhancing outgoing and incoming signals.  Unwanted signal components in the outgoing direction, caused by cross coupling via the transformer of incoming signals, are minimized by employing a canceller network in circuit with the incoming and outgoing amplifiers.          The canceller network has a complex transfer characteristic to compensate substantially for complex impedance components of the coupling transformer and 2-wire transmission facility and to generate a signal which is substantially a replica of the unwanted outgoing signal components.  The replica signal and unwanted signal components are algebraically combined in the outgoing amplifier effectively to eliminate the unwanted signal components from the outgoing path.  In a first embodiment the canceller network has an attenuation versus frequency characteristic yielding a prescribed second-order complex transfer characteristic while in a second embodiment the canceller network has an attenuation versus frequency characteristic yielding a prescribed fourth-order complex transfer characteristic.  In the second embodiment values of predetermined pole-zero pairs are selectively adjustable to match impedance components of different 2-wire transmission facilities.

Abstract: BOTTLE MULTIPACKAGE                             Abstract A multipackage of a group of bottles and a bag-like or bundling device. The group of bottles are arranged in two adjacent rows and in transverse ranks perpendicular to the rows. The bag-like device is formed from a thin flexible material and essentially comprises three elements, a band portion that securely encircles the sidewall peripheral surface of the group of bottles, a bottom wall that is integrally connected between the lower edges of at least two sidewalls of the device, and an upper portion that comprises a gathered and secured arrangement of at least a pair of flaps integrally connected to the upper ends of two opposed sidewalls of the device. The gathered and secured flaps are arranged to form two secured intersecting tensioned truss elements that extend diagonally from opposite corners of the group of bottles. The secured intersection of the tensioned truss elements is substantially at the height of the bottle caps of the group of bottles and substantially midway between the bottles of the center rank of bottles. Importantly, the formed truss elements are sufficiently tensioned to substantially prevent skewing of the group of bottles out of the transverse ranks perpendicular to the rows. Further importantly, the secured intersection of the tensioned truss elements is of a reduced cross section and circumferentially open to form a handle element capable of being encircled by a person's finger for convenient transport of the package. In such a carrying arrangement, the load of the bottles in the bag-like device is effectively directed from substantially the entire circumferential band portion through the tensioned truss elements to the handle element.

Abstract: ELECTRIC RESISTANCE HUMIDIFIER                      ABSTRACT OF THE DISCLOSURE    An electric resistance humidifier which increases atmo-spheric humidity by boiling water in a tank.  Spaced conductive plates, or electrodes, are fixed in the tank.  As the tank water level rises, the immersed area of the electrodes increases.          An electric supply causes the electrodes to pass electric cur-rent through the tank water therebetween for heating and vapor-izing such water.  Electric current and heating cease automat-ically when the tank water level falls below the electrodes.  A control includes comparator circuitry responsive to a reference signal and a signal related to electrode current for actuating and deactuating a water supply to the tank.  In one embodiment, the control includes further comparator circuitry responsive to electrode current and a further reference signal for controlling a tank drain, to compensate for rising conductivity of the tank water as it warms toward boil and thus prevent substantial over-shoot in heating current flow.  In one embodiment, humidity sensing circuitry varies the reference signal level, to increase the upper water level limit in the tank, and hence heating cur-rent flow and speed of vaporization, in response to decreasing atmospheric humidity, thereby to increase atmospheric humidity to a desired level.  The aforementioned apparatus, if desired with a fan for distributing vapor boiled from the tank water, is housed in a cabinet.  A manual adjustor for selecting a fixed reference or humidity level is conveniently located on a panel of the cabinet.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed herein is a ring laser gyroscope of the type which operates with four circularly polarized beams at four mutually distinct frequencies, with two oppositely circularly polarized beams propagating in one direction and the two other oppositely circularly polarized beams propagating in the opposite direction.  The ring laser gyroscope comprised two different gas isotopes as the active components of the laser gain medium, there being provided means for applying a magnetic field, whose direction substantially coincides with the beam directions, to the gain medium, i.e. the two gas isotopes, suitably in the form of DC current-carrying coils wound around the tube containing the gain medium, thereby to generate las-ing action at the four frequencies.  The complete gyro-scope includes means for detecting beat frequencies re-sulting from combining the beams and means receiving the output from the detecting means for generating output sig-nals which are representative of rotational displacement of the ring laser gyroscope.
