Abstract: An in-band television signal sync suppression scrambling system has two sync suppression modes which are aperiodically alternated. Horizontal and vertical synchronizing pulses are equally suppressed in one mode, and are suppressed to different levels in a dual modulus mode. In single modulus mode, horizontal and vertical sync pulses are both suppressed at 6 dB. In the dual modulus mode, sync suppression is dynamically shifted between 10 db suppression for horizontal sync pulses and 6 db for the vertical interval. Mode control data is conveyed on the audio carrier and is detected by decoding circuitry which enables the restoration of synchronization pulses in the scrambled television signal according to the mode indicated. Mode changes are aperiodically changed depending upon the scene content in the TV picture or a random generator.

The flange includes an interior support surface which is substantially concentric with the outer surface of the serrations and the inner, axially extending wall portion of the boss is contiguous with this inner support surface in order to provide back-up support and preclude close-in of the closure and distortion of the closure threads during the crimping operation and during subsequent stress-inducing operations such as exposure to high-temperature sources.

Abstract: A load management system for a power network which both addresses remote load controllers and acquires load data through a retransmission network. A central controller processes power load a data and generates digital messages which address loads and command the selective connection and disconnection of loads. The central controller transmits the generated digital messages via radio frequency transmissions. Programmable retransmission stations receive, decode and directionally retransmit the digital messages. Addressable remote load controllers receive and decode transmitted digital messages and operate to connect and disconnect loads in response to command messages received by the addressed load controllers. Addressable data acquisition units sense loads at points in the power network and operate to generate digital load data messages.

Abstract: An apparatus and method is detailed for the application of non-conductive material, generally of a powder or fine fiber form from bulk storage onto a conductive filament or plurality of filaments. A series of vibrating troughs are used to store, convey, unpack and load particulate material at a controllable rate into a gas stream traversing a converging-diverging nozzle. High aerodynamic shear in the nozzle reduces the material's size. Divergent nozzle exit geometry slows the material to speeds where electrostatic forces can predominate, as the material is injected upwardly into a chamber fitted with a cascade of conical forms. Each cone is electrified about its circumference in one or more locations, with respect to a centrally located upward moving filament. Conventional electrostatic charging and deposition on the filament is augmented by the convergent geometry of the cones. Excess material falls on the outside of the cones, and eventually downward to a recovery area.
