Title: Coating of inorganic multicellular particles in bonding material on plastic pipe
Inventor: MAGARIAN GERALD M
IPC: F16L57/06
Filed: 1975-09-10
Granted: 1979-10-23
Abstract: ABSTRACT OF THE DISCLOSURE An energy-absorbing protective coating is bonded to the exterior of a plastic pipe.  Preferably, the coating is a layer of low-cost, crushable, multicellular, inorganic particles, such as natural volcanic lightweight aggregate, expanded shale, expanded clay, pumice, slag, or furnace cinder, embedded in a thin film of plastic resin.  the particles crush by breaking upon impact, which absorbs the energy of the impact and protects the pipe from damage.

Abstract: ABSTRACT OF THE DISCLOSURE A remote meter-reading system interrogates meter stations over power lines and receives encoded meter readings over the power lines in synchronism with the power line frequency by super-imposing a digitally modulated signal over the 60-Hz power frequency.  The central control station transmits at a data rate of 60-baud and receives at a data rate that is 60-baud or a submultiple thereof, to reduce the demands on the remote meter station transceiver as compared to those on the central control unit transceiver.  The bit clock at the central control unit and the meter stations is derived from the 60-Hz power line phase available at each station.  Each meter station achieves message synchronization by continuously monitoring the data bit stream for a preset synchronization code and thereafter treats the following 21 data bits as address and function codes. Each meter station that is addressed responds at the data rate designated by the function code by transmitting with a message including the address and function bits for comparison at the central control station with that originally sent to facilitate error detection, and the meter reading encoded according to an error detecting code.  A binary data bit is represented by quadrature phase lead and lag relative to reference phase of the character.

Abstract: ABSTRACT:          A record carrier is described in which a tele-vision signal is stored in an optically readable infor-mation structure of trackwise arranged areas alternat-ing with intermediate areas. The tracks exhibit an un-dulation. The luminance information is contained in the spatial frequency of the areas and the other information, for example chrominance and sound information, in the variation of the undulation. The luminance information and the other information can be read independently by means of a suitable detector arrangement.

Abstract: A METHOD FOR FORMING RECESSED DIELECTRIC ISOLATION       WITH A MINIMIZED "BIRD'S BEAK" PROBLEM                    ABSTRACT OF THE INVENTION     In the fabrication of integrated circuits, a method is provided for forming recessed silicon dioxide isolation in integrated circuits in which the "bird's beak" problems associated with conventional sili-con dioxide-silicon nitride composite masking structures is minimized. A conventional composite mask comprising a bottom layer of silicon dioxide and an upper layer of silicon nitride having a plurality of openings defining the regions in the silicon substrate which are to be thermally oxidized is formed on a silicon substrate.  Recesses are then etched in the silicon substrate in registration with the openings in the composite mask. Then, the silicon dioxide layer is, in effect, over-etched to extend the openings in the silicon dioxide to greater lateral dimensions than the openings in the silicon nitride layer whereby the silicon nitride at the periphery of the openings is under-cut.      A layer of silicon is then deposited in the recesses covering the undercut portions of said silicon nitride layer.  Then, the structure subjected to thermal oxidation whereby the silicon in and abutting the recesses is oxidized to form regions of recessed silicon dioxide substantially coplanar with the unrecessed portions of the silicon substrate.  Because of the undercutting and the deposition of silicon in the recesses, the "bird's beak" effect is minimized.

Abstract: ABSTRACT OF THE DISCLOSURE               DC power at a first voltage level in a first line is transformed into DC power at a second voltage level in a second line.  An inverter having its DC terminals connected between the first line and the second line conducts the current from the first line to the second line.  This inverter also converts a portion of the DC power in the first line into AC power.  A rectifier having its DC terminals connected between the system return and the second line is driven by the AC power provided by the inverter.  The turns ratios of the transformers associated with the inverter and the rectifier establishes the voltage level at the second line as well as the current to be supplied to the second line by the rectifier.

Abstract: INTERLEAVED ANTENNA ARRAY FOR USE IN A MULTIPLE INPUT ANTENNA SYSTEM                         ABSTRACT    An interleaved antenna array is disclosed in conjunction with an improved multiple transmitter antenna system for simultaneously generating two independent groups of com-posite radiation patterns for two separate pluralities of independent radio devices.  A first plurality of isolated independent radio transmitters is coupled, without any signal cancellation, to each and every one of a first plurality of independent antenna elements which form a first group of composite radiation patterns for these trans-mitters.  A second plurality of transmitters is likewise coupled to a second plurality of antenna elements which create a second group of composite patterns for these transmitters.  The antenna elements  of the first and second pluralities are alternately circumferentially disposed about a central axis and each produces a 90° half power beam width radiation pattern which is directed radially away from the central axis.  First and second combining networks produce 90° electrical phase shifts  between the adjacent radiation patterns produced by the elements in each of the two pluralities, respectively.  By providing such an interleaved antenna array for first and second pluralities of indep-endent transmitters, a single multiple input antenna system is provided which has a small size and produces a uniform omnidirectional pattern for each of the transmitters while maintaining isolation between each transmitter.
