Granted: 2003-12-30
Abstract: Lift wheel structure for an implement includes four bar linkage having a curved lower link connected to the frame closely adjacent a first tool-carrying rank. A  caster wheel is supported at the forward end of the linkage for castering in an accommodation area defined by the curved lower link. Plates are bolted to the sides of the lower link and extend along sides of an upper link to a connection with a lift cylinder directly above the upper link. The link and the cylinder closely overlie the frame to limit interference with other components mounted above the frame and to facilitate compact folding of implement sections. Loads, including cylinder lift loads, are transmitted primarily through the lower link. A protected transducer assembly is connected between the lower link and the frame to maximize and linearize transducer response in the depth control range. The lift wheel structure can by mounted at different locations on the frame to accommodate different tool configurations and provide the desired automatic depth control and leveling functions. In one embodiment a tension link connects a forward four bar linkage wheel structure with a rear single pivot lift wheel structure such that level lift is provided.

Abstract: An amplifier apparatus for a multimode mobile communication device includes a carrier amplifier (114) and a peaking amplifier (116). The peaking amplifier has an adjustable bias level and is adjusted by a regulator to a predetermined level, depending on which mode of communication is selected. The bias level on the peaking amplifier is held constant so long as the mode of communication is the same. By adjusting the bias point of the peaking amplifier in conjunction with the selection of the mode of communication, the efficiency and the linearity of modulation can be optimized for the particular mode of communication.

Abstract: L'invention concerne un mécanisme de remplacement dans un dispositif implantable, qui répond au besoin des médecins en électrogramme mémorisé et/ou autre signal physiologique mémorisé, associés à une arrhytmie détectée ou à tout autre événement physiologique, sans le drain de courant indésirable associé au fonctionnement continu d'un amplificateur de détection et d'une mémoire d'itération. Le dispositif active régulièrement mais par intermittence un amplificateur de détection ou un autre capteur et des circuits de mémoire associés, indépendamment de la détection de l'arythmie. Le dispositif peut mémoriser temporairement seulement un seul article, le remplacer par de nouveaux articles à mesure qu'ils sont mémorisés, ou mémoriser de multiples articles, remplacer l'article le plus ancien par l'article mémorisé le plus récent. Lors de la détection d'une arythmie ou de tout autre événement physiologique défini, le dispositif peut simplement transférer la ou les bandes d'électrogramme mémorisées temporairement à une mémoire permanente, de sorte qu'elles puissent être utilisées ultérieurement par le médecin dans le diagnostic de l'état du patient avant la détection de l'événement.

Title: Method and apparatus for fluid jet formation
Inventor: HASHISH MOHAMED A
IPC: B26F3/00
Filed: 2000-03-08
Granted: 2009-09-15
Abstract: A method and apparatus for controlling the coherence of a high-pressure fluid jet directed toward a selected surface. In one embodiment, the coherence is controlled by manipulating a turbulence level of the fluid forming the fluid jet. The turbulence level can be manipulated upstream or downstream of a nozzle orifice (30) through which the fluid passes. For ex-ample, in one embodiment, the fluid is a first fluid and a secondary fluid is entrained with the first fluid. The resulting fluid jet, which includes both the primary and secondary fluids, can be directed toward the selected surface so as to cut, mill, roughen, peen, or otherwise treat the selected surface. The charac-teristics of the secondary fluid can be selected to either increase or decrease the coherence of the fluid jet. In other embodiments, turbulence generators (75), such as inverted conical channels, upstream orifices, protrusions and other de-vices can be positioned upstream of the nozzle orifice to control the coherence of the resulting fluid jet.

Granted: 2009-11-10
Abstract: The invention relates to a process for producing a corrosion-resistant blasting agent ( > 60 HRC) with sharp edges based on an Fe-Cr-C alloy. A granulate consisting of an iron-chromium-carbon alloy is hardened in said process to > 60 HRC by subjecting it to a heat treatment at above 900° Celsius under a reducing atmosphere. An oxide-free, hard material is obtained in this way that can be crushed into grains with sharp edges. The result is a blasting agent with excellent properties for the surface treatment of workpieces consisting of corrosion-resistant materials such as, for example stainless steel, nonferrous metals and natural stone.
