Title: Tv interface rf modulation circuitry
Inventor: HUNTER RICHARD E JR
IPC: H04N5/775
Filed: 1981-07-31
Granted: 1984-03-06
Abstract: RCA 76, 091 Abstract of the Disclosure An interface circuit for selectively generating TV RF signals on one of two adjacent TV channels is designed with two independent RF oscillator-modulator circuits. The respective double sideband modulated signals generated by the RF modulators are respectively passed through separate frequency rejection filters designed to attenuate the lower sound sideband of each of the modulated signals. The resultant signals are applied to a common bandpass filter via an isolation network. The pass band of the bandpass filter encompasses substantially the combination of the pass bands of the broadcast TV channels corresponding to the RF signals generated. Consequently the lower frequency RF modulated signal is similar to a conventional vestigal sideband TV signal and the higher frequency RF modulated signal is a double sideband signal minus the lower sound sideband. The isolation network provides electrical connection between the rejection filters and the bandpass filter but establishes a relatively constant impedance-at the respective filter output and input terminals irrespective of changes in the filter impedances so that the filters may be tuned to the desired resonances without interaction between respective filter circuits.

Abstract: ABSTRACT          This invention relates generally to electrical connectors and more particularly to improved modular inter-face connectors and connector assemblies incorporating such modular connectors.  A continuing problem with present con-nectars and connector assemblies is that a wide variety of assembly component parts are necessary to meet different connection requirements inasmuch as different connector assemblies, such as adapters, bridging assemblies, data sets, junction assemblies, and the like, having non-inter-changeable components are required for various different connection purposes.  The present invention is designed to provide a slidingly mountable modular connector capable of easy installation and replacement coupled with reliable operation.  The modular connectors of the invention include improved mounting structures which permit each connector to be slidably mounted on a support member in at least two alternate orientations and to be retained at any position between two spaced shoulders of the support member.  In addition, the modular connector is preferably an integrally molded plastic unit configured to permit its fabrication in a single-action mold.  In one embodiment, the interface con-nector further includes a removable comb member which separates and aligns the active portions of the connector contact elements and prevents access through the entrance aperture of the connector to the free ends of the contact elements.  In another embodiment, the interface connector includes an integral comb structure and embossments disposed on the connector housing for engaging and mounting at least one bus bar member to the housing adjacent the comb structure.

Abstract: ABSTRACT OF THE DISCLOSURE An electrophotographic printing machine in which an original document is reproduced on a copy sheet. The printing machine includes a photoconductive belt arranged to move in a recirculating path. As the photoconductive belt moves through a first cycle, a combined charging-transferring unit charges at least a portion of the photoconductive belt, and a combined exposing-discharging unit focuses a light image of the original document thereon. This records an electrostatic latent image on the photo-conductive belt which is developed by a combined developing-cleaning unit. During the second cycle, the charging-transferring unit transfers the toner powder image to the copy sheet, and the combined developing-cleaning unit removes residual particles from the photoconductive belt. After cleaning, the combined exposing-discharging unit illuminates the photoconductive belt to eliminate any charge remaining thereon.

Abstract: Abstract An article having a flange is molded between a mold core and a unitary mold cavity, the flange being formed during the process as a consequence of the existence of an undercut existing in a first surface of the cavity.  A ridge is provided on a second surface of the mold cavity adjacent the undercut.  A fluid, i.e., air, is injected between the cavity and the molded article as the core and cavity separate in such a volume and at such a pressure as will maintain the article in substantially complete and constant contact with the core as the core and article are withdrawn from the cavity.  The flange conforms to the cavity wall until the article is free from the cavity, and subsequently the molded article is separated from the mold core.

Abstract: PREPARATION PROCESS OF INDOLE                       Abstract Disclosed herein is an improved preparation process of indole from aniline and ethylene glycol.  Upon preparing indole by reacting aniline and ethylene glycol in a gas phase and in the presence of a catalyst, ethylene glycol is charged in portions to a multiplicity of catalyst stages formed by dividing a catalyst bed and connected in series.          This divided supply of ethylene glycol permits to make the concentration of ethylene glycol in the catalyst bed uniform and is thus effective to suppress the decomposition of ethylene glycol due to development of localized heat spots, even if the molar ratio of feed aniline to total feed ethylene glycol is small.  The above process permits to make the molar ratio of feed aniline to total feed ethylene glycol small so as to reduce the amount of unreacted aniline to be separated and recovered from the reaction effluent.

Abstract: ABSTRACT      An improved oxygen sensing cell, especially of the polarographic type, is intended for use primarily in a gaseous environment.  The cell has a cathode located at the bottom of the cell body. The cathode comprises a gold mesh electrode laminated to a thin-film sense membrane.  The electrode is thus made immobile relative to the membrane, thereby improving the response time and providing for long-term sensor stability.  The cell further has a guard electrode for the cathode.  The guard electrode operates contin-uously and scavenges any oxygen molecules which are dissolved in the electrolyte and diffused towards the cathode.  As a result, the dynamic range of the cell is substantially increased.  The anode comprises a silver wire wound about a spool retained within the main cavity in the cell body. A p.c. board, as well as a compensation membrane, are resiliently retained at the top of the cell body.  The body carries conductors for electric-ally connecting the p.c. board with the anode, cathode, and guard electrode, respectively.
