Filed: 1999-08-25
Abstract: This invention relates to high power linear amplifiers. A high power linear amplifier is disclosed for communications such as CDMA communication systems. Linear amplifiers as used in communication systems exhibit a linear characteristic where the amplifiers output power increases relative to an input power. After a certain input level, known as a gain saturation point, the amplifier then exhibits non-linear characteristics; the output power increases relatively little with respect to power input. This non-linear region is also known as the saturation region or the gain compression region. In accordance with the invention, there is provided a power amplifier comprising a power amplifier, a feedback circuit and a control element; wherein the feedback circuit receives a sample of the input signal delayed in time and employs phase and amplitude components of both the input signal delayed in time and a feedback signal derived from the output of the power amplifier to drive a control element, which control element determines the signal input to the amplifier whereby the power amplifier can produce an improved linear output.

Abstract: A flat fold hinge assembly for implement frame sections that fold substantially greater than 90 degrees includes a modular hinge having first and second hinge portions that bolt solidly to the frame sections. A folding cylinder is protectively cradled between the sides of a cast mounting bracket closely adjacent the frame tube. Floating links are connected to the rod end of the cylinder generally below the main pivot which is offset above the frame tube a distance substantially less than most previously available hinge structures for compact storage of the wing frame close to the inner frame. The design, preferably utilizing four cast components, is more compact than previous designs so the frame sections fold more compactly. The simple mounting arrangement provides versatility in locating the hinge assembly to accommodate a wide variety implement configurations and implement attachments. The hinge structure acts to reinforce the tubular frame construction and distribute heavy loads transferred from implement attachments and tools. A  mounting area on the hinge facilitates connection of additional hardware such as a wing support tube truss.

Abstract: L'invention concerne un filtre composé d'un corps sensiblement cylindrique ou légèrement conique présentant un certain nombre d'ouvertures allongées sur toute sa périphérie. Chaque ouverture est définie horizontalement par l'espace s'inscrivant entre deux baguettes cunéiformes et verticalement par deux éléments transversaux présentant une partie supérieure sensiblement carrée et une partie inférieure évasée. Il en résulte une ouverture sensiblement rectangulaire destinée à l'écoulement du fluide et un côté inférieur évasé opposant une légère résistance à l'écoulement. L'invention porte également sur un procédé de fabrication de filtres présentant les caractéristiques susmentionnées. Selon le procédé préféré, on emploie une technique de moulage par injection qui consiste à injecter un plastique fondu (tel qu'un polyéthylène haute densité, (HDPE) dans un moule composé de deux parties. Celui-ci comprend généralement une cavité lisse et sensiblement cylindrique et un noyau dentelé et canulé inséré dans la cavité, les surfaces de ces deux éléments entrant partiellement en contact pour former le moule du filtre. Etant donné que le contact entre les deux surfaces doit se conformer à des tolérances extrêmement étroites, des modifications relatives à l'alignement du moule ont également été apportées.
