Patent BR-8402637-A (BR)
Inventor: HEWLITT ROBERT WILLIAM
IPC: F02F1/24
Filed: 1984-05-31
Abstract: A load carrying assembly is disclosed for an internal combustion engine. The engine includes an engine block having a cylinder formed therein and having a cylinder head mounted onto the block. The cylinder head has a deck surface which closes off one end of the cylinder. A piston is reciprocally mounted in the cylinder and cooperates with the deck surface to form a combustion chamber. Air and combustion gases enter and exit the combustion chamber through intake and exhaust passages formed in the cylinder head and which terminate into intake and exhaust ports formed in the deck surface. The outer peripheries of the adjacent intake and exhaust ports form a bridge section therebetween having a maximum length which is less than twice the diameter of the larger of the intake and exhaust ports. Formed at least partially within the bridge section is a nozzle bore which also communicates with the combustion chamber. A sleeve having an enlarged portion on its outside diameter, is permanently fixed within the cylinder head such that one end will be aligned approximately adjacent to the deck surface of the cylinder head. The sleeve serves as a load carrying member which reduces the initiation of thermal cracks in the bridge section between the outer circumference of the nozzle bore and the outer peripheries of the intake and exhaust ports, respectively.

Inventor: MCKELVEY JAMES M
IPC: B29C48/41
Filed: 1984-12-04
Abstract: A gear pump assisted screw conveyor extrusion system utilizing a cartridge heating device disposed axially within the screw and having the drives for the gear pump and the screw correlated in speed to create relatively little pressure in the thermoplastic material being extruded such that relatively little mechanical working thereof occurs. The thermoplastic material is melted in the screw conveyor primarily by heat transfer from the cartridge heater and the gear pump is utilized for conveying the melted material under pressure to a subsequent work station. A relatively deep material-conveying spiral channel is provided in the screw for maximized extrusion output per revolution of the screw and minimized mechanical energy generation by the screw. A motionless mixer may be employed intermediate the screw and the work station to homogenize the melted material for reducing temperature gradients therein. The system advantageously is capable of extruding material at a substantially greater rate and a lower material temperature and with substantially increased power economy than conventional systems utilizing a high pressure, externally heated screw conveyor portion.

Abstract: A method and apparatus are described for adjusting clock pulses of time-equidistant digital line scanning values of a moving-image signal present in a composite color video signal to a clock used in a digital transmission link by means of a moving-image coder. In the transmitting part (10) of the moving-image coder, self-identifying stuffing characters are inserted into the string of image scanning values if clock deviations are found. The identification may be carried out by means of an additional bit or, alternatively, by a special code word when this is first removed from the supply of image scanning values. In the receiving part (30) of the moving-image coder, the stuffing character is recognized and removed and the original character string is restored.

Abstract: In order to produce a more well defined interface between adjacent cell layers in a centrifuged sample of anticoagulated whole blood, e.g. between the erythrocytes and the leukocytes, a material which will selectively bond one group of cells together, e.g. the erythrocytes, is added to the blood sample prior to centrifugation. The bonding material must produce a high strength bond between one group of cells, but not affect the other cell types. The material is added prior to centrifugation of the blood sample.

Abstract: Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have a unique elastic waist feature that improve the dynamic fit of the elasticized waistband as well as the containment characteristics of the absorbent article. The elastic waist feature comprises an "expansive tummy panel" that is capable of expanding well-beyond the dimensions of the absorbent article set by the primary fastening system (and the original dimensions of the end edge) so as to accommodate wearers, especially large infants, with large expansile waists so as to reduce the sagging/slipping of the absorbent article. The extension forces of the elasticized waistband are lower than the extension forces of the elasticized side panels so as to accommodate such expansion. In preferred embodiments of the elastic waist feature, the elasticized waistband is formed from a stretch laminate.

Abstract: A centrifugal pot spinning process for spinning yarn of classical character is provided in which either in one stage a fully twisted yarn or in a first stage a partially twisted yarn is spun in a centrifuge (6) and removed from it and, in the case of the partially twisted yarn, the remaining twist is imparted to the yarn in a second stage upon removal while being wound up. A centrifuge (6), a drawing frame (1), a piecing mechanism (2), and a traversing thread guide tube (4) are used. The centrifuge (6) rotates in a space (7) under reduced pressure (pu). Normal air pressure (pn) prevails inside the centrifuge (6) and spinning is carried out under normal air pressure (pn) inside the centrifuge. The reduced pressure (pu) is adjusted in such a way that, during rotation of the centrifuge (6), essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge (6, 35, 45, 53) against the housing (5') is largely suppressed. A vacuum centrifuge (5) is positioned so as to pivot inside the housing (5'). The space (7) between the centrifuge (6) and the housing (5') can be placed under variable reduced pressure (pu). The reduced pressure is adjustable in such a way that, during rotation, essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge is largely suppressed.

Abstract: An improved submerged entry nozzle is provided which is useful in the casting of aluminum killed molten steel. The nozzle has an improved slagline sleeve or collar which surrounds the outer portion of the nozzle to protect it from corrosion during the casting process. The slagline sleeve is made from resin bonded zirconia/graphite which has been formulated so that upon curing of the resin to form resite, there is a reduction in the contractile tendency which results in a reduction in stress fracturing. The reduction of the contractile tendency and the resulting resistance to stress fracturing is achieved by adding an effective amount of calcium oxide to the resin-zirconia-graphite mixture which is used to form the sleeve.

Abstract: Patente de Invenção: "SENSOR CAPACITIVO DE NìVEL DE ENCHIMENTO COM GEOMETRIA DE ELETRODO OTIMIZADA". A presente invenção refere-se tem como objetivo a otimização de um sensor de nível capacitivo, o qual é apropriado especialmente para determinação de local de uma camada limite 12 entre a água 10 e o óleo 11 em um tanque separador. O princípio de sensor conhecido baseia-se no fato de que se mede a capacidade dependente do ambiente entre eletrodos adjacentes 13, 4; 4, 5; 5, 6 de uma sonda em forma de haste 1. De acordo com a invenção, a sonda 1 é projetada de tal modo que, no meio condutor 1 0, ocorrem grandes capacidades iónicas de camada dupla nos eletrodos 4, 5, 6, 13 e, no meio isolante 11, ocorrem pequenas capacidades entre os eletrodos 4, 5, 6, 13. Para isto, escolhe-se uma altura de eletrodo h grande, a razão de altura de eletrodo h para a distância de elétrodo "a", preferivelmente na faixa 1 < h/a < 6, e especialmente a freq³ência de medição f entre as freq³ências elétricas limites dos meios 10, 11. Assim, são alcançáveis um salto de capacidade grande para uma indicação digital de nível e/ou um aumento de capacidade substancialmente contínuo para uma indicação analógica de nível. Além disso, a influência de películas de sujeira 14 condutora e/ou isolante sobre o sinal de capacidade é eliminada através de freq³ências de medição apropriadas e/ou através de deslocamento radial dos eletrodos 4, 5, 6, 13.
