Patent BR-8501965-A (BR)
Inventor: KIEWIT DAVID A
IPC: H04N17/00
Filed: 1985-04-25
Abstract: A system for identifying signals such as signals representative of television programs received from various sources detects the occurrence of predetermined events such as scene changes in the video signal and extracts a signature from the signal. The signatures and the times of occurrence of the signature are stored and subsequently compared with reference signatures to identify the signal. The signature may be compared in pairs to increase resolution, and the time interval between events or signatures may also be used to identify the signal, either by themselves or in conjunction with the signatures.

Abstract: This invention relates to a method and an apparatus for the production of ribbed pipes. The apparatus comprises a core (8, 9, 10) which together with an extrusion sleeve (4) forms a nozzle (11) through which a plastic material is fed into a moulding space (12) defined between a mandrel (9) and chill moulds (1, 2) moveable with respect to the mandrel. Ribbed pipes produced by means of known apparatuses have, for various reasons, an uneven inner face, incomplete ribs or air closures and weak seams in the pipe walls and ribs. These disadvantages can be eliminated by such a dimensioning of the moulding space (12) of the apparatus and the grooves (13) of the chill moulds that the volume of a space defined between a plane (20) extending adjacent to the end face of the extrusion sleeve, a surface (16) of the mandrel, and a plane (17) comprising the envelope surface of the kernel (10) equals to the combined volume of the grooves (13) positioned within the area of the mandrel at each particular moment.

Abstract: Linear ethylene interpolymer blends are disclosed. The blends are made from components having a narrow molecular weight distribution (e.g. Mw/Mn  </=  3) and a narrow composition distribution (e.g. CDBI > 50 %). The blend components in a blend can all have the same molecular weight but different comonomer contents, the same comonomer content but different molecular weights, or comonomer contents which increase with molecular weight. The blends have either Mw/Mn > 3 or CDBI < 50 %, or both, and can be multimodal with respect to either or both molecular weight and/or comonomer content. The blends are generally free of blend components having both a higher average molecular weight and a lower average comonomer content than another blend component. The blends can have improved mechanical, physical and/or chemical properties.

Abstract: A multiconductor and support has a plurality of elongate conductive elements (19) each with a pair of termini. An elongate support means (20), carrying adjacent conductive elements, has openings (32) located at the distal and the proximal ends for alignment with conductive elements extending thereover leaving the distal termini thereof unsupported. Heat activated adhesive on the support means bonds the conductive elements. Each of the conductive elements are spaced from the other conductive elements and have center lines which are parallel. A machine for assembly of a multiconductor and support means has a plurality of spools supplying conductive elements and a plurality of guides each positioned to receive and align the supplied conductive elements. The guides position the conductive elements spaced from and parallel to each other. A supply of support means moves support means intermittently but synchronously between the conductive elements and a flat surface. A heated platten compresses and bonds the conductive elements and the support means into an pair. A method for assembling a multiconductor and support includes intermittently moving several conductive elements in parallel spaced relation and intermittently moving a support means in a plane parallel to the conductive elements. Pressing the parallel conductive elements and the support means together forms the pair. <IMAGE>

Abstract: Patente de Invenção: <B>"APARELHO E PROCESSO DE TRANSMISSãO E RECEPçãO INCLUINDO CODIFICAçãO E DECODIFICAçãO CONVOLUCIONAL 'PUNCTURADA'". Dados digitais (particularmente sinais de programa de televisão codificados) são comunicados por um transmissor para um receptor terrestre pela codificação convolucional dos dados em um primeiro e um segundo sinal durante diferentes períodos representando um sinal de 1/2 taxa. Durante os diferentes períodos, os dois sinais são combinados e puncturados em um fluxo de bit puncturado serial para produzir um sinal convolucionalmente codificado de correção de erro antecipada tendo uma taxa automaticamente ou manualmente selecionada p.ex. taxa de 2/3 ou de 6/7. Os sinais sendo codificados em taxa variáveis diferentes são transmitidos em tempos mutuamente exclusivos a primeiro e segundo níveis de potência para o receptor via um satélite. às taxas variáveis, fluxos de bit puncturados paralelos são simultaneamente derivados e modulam simultaneamente o par de portadoras ortogonais (QPSK). O processo de puncturação aperfeiçoado é suscetível de processar todos os códigos puncturados ideais e utiliza um relógio puncturado, multiplexador, FIFO, RAM, ROM, fonte de controle de taxa. O pulso de relógio puncturado é usado para derivar um par de trens de ondas compreendendo os bits seq³enciais de canais I e Q e bits fictícios inseridos no sinal serial. O receptor responde à portadora QPSK e deriva um primeiro sinal serial tendo um fluxo de bit seq³encial de bits seq³enciais alternados tanto em I como de Q. Outrossim, eles são seq³encialmente redistribuídos como sinais de I e Q nos mesmos intervalos de tempo.

Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Use of the nucleotide sequences to mediate fertility in plants is also described. In one such method, an inducible promoter is used to regulate expression of the DNA molecule. The control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.

Abstract: In a tyre tread band for medium/heavy duty motor-vehicles a tread band is provided with circumferential grooves (2a, 2b, 2c) confining three pairs of respectively centre (5c), intermediate (5b) and shoulder ribs (5a). Respective blocks (7b, 7a) are defined along the centre and intermediate ribs and they are confined by transverse cuts (8b, 8a). The centre cuts (8b) impart a cusp-shaped end conformation (9) and a hollow-shaped end conformation (10) to the respective blocks (7b), and the shapes of said end portions mutually match. The intermediate cuts (8a) run in the linear extension of the centre cuts (8b) to give the respective blocks a rhomboidal configuration. The tyre can be alternately associated with a driving axle or a driven axle, by merely reversing its direction of rotation, so that the following results are selectively achieved: an increase in the traction capability by the intermediate blocks or an increase in the directional capability as a result of the mutual wedging between the centre blocks at the ground-contacting area. <IMAGE>

Abstract: An automatic gain control (AGC) apparatus for a digital receiver is disclosed herein. The AGC apparatus includes an adjustable gain amplifier having an input port for receiving an input signal, a control port for receiving a gain control signal, and an output port for providing an output signal. The AGC apparatus further includes a measurement circuit for generating a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and generates an gain control signal in response to a result of the comparison. The saturating integrator includes a decision circuit for enabling integration based on values of the received power signal, the reference signal, and the gain control signal. In a preferred implementation the utilization of an input limiter in conjunction with an analog to digital converter enables accommodation of an increased input signal dynamic range. Accordingly, the AGC apparatus is capable of being used in digital demodulation of FM signals. The AGC apparatus may also be employed within a dual mode receiver designed to process both FM and code division multiple access (CDMA) input signals.
