Title: Apparatus for diverting a stream of articles
Inventor: DEPASO JOSEPH M
IPC: B65G47/52
Filed: 2002-03-08
Abstract: Apparatus for diverting a stream of articles from one conveyor to another parallel conveyor moving in an opposite direction in a conveyor bed. A diverter element (44) is attached to a carrier that is driven along a path parallel to the two conveyors by a differential drive mechanism coupled to t he drive mechanisms of the two conveyors. The differential drive mechanism responds to the difference in the speeds of the two conveyor drive mechanism s to drive the carrier and position the diverter element along the parallel conveyors. The diverter element (44) extends at least partway across the widths of the two conveyors to guide articles on one conveyor to the other. In a preferred version, the carrier is an endless conveyor belt (46) to which t he diverter element is attached, and the differential drive mechanism includes a shaft arranged coaxially with drive or idler sprocket shafts of the conveyor  belts at each end of the bed. The apparatus is useful in accumulating articl es transported on a main conveyor in a first in, first-out fashion.

Title: Method and apparatus for subsurface fluid sampling
Inventor: ZAZOVSKY ALEXANDER
IPC: E21B49/08
Filed: 2003-04-28
Abstract: An apparatus and method for extracting fluid from a subsurface formation is disclosed. A downhole sampling tool is provided with a probe having an internal wall capable of selectively diverting virgin fluids into one or more virgin flow channels for sampling, while diverting contaminated fluids into one or more contaminated flow channels to be discarded. The characteristics of the fluid passing through the channels of the probe may also be measured using techniques, such as optical density, to evaluate various fluid parameters, such as contamination levels. The data generated during sampling may be sent to a controller capable of generating data, communicating and/or sending command signals. The flow of fluid into the downhole tool may be selectively adjusted to optimize the flow of fluid into the channels by adjusting the internal wall within the probe and/or by adjusting the flow rates through the channels. The configuration of the internal wall and/or the flow rates may be automatically adjusted by the controller and/or manually manipulated to further optimize the fluid flow.

Abstract: An Internet based method for assisting in the rapid delivery of medical information direct to the site at which emergency assistance is being perfomed uses a global database for warehousing patient history information, which is fetched over the Internet on demand. In one embodiment, medical providers use an access code carried by the injured party and without without which access is denied. The access code may be carried as a barcode and as an imprinted number on a bracelet or on a card carried by the individual. Patient information is transmitted over a network, either wireline or wireless, the Internet or wide area network, to a computer or personal digital assistant available to emergency personnal. In one embodiment, entering the patient access is determined through the use of an access code code reader, by entering the patient access code manually or by made available to shorten emergency room admission procedures. Lastely, the patient's card or bracelet can allow for patient history to be downloaded and saved. Thus in emergency situations, the information can be uploaded from the card or bracelet to the healthcare providers' viewing screens.

Filed: 2002-05-30
Abstract: La présente invention concerne des systèmes et des procédés permettant de détecter des paroles voisées et non voisées dans des signaux acoustiques dont les niveaux de bruit de fond varient. Ces systèmes (fig. 3) reçoivent des signaux acoustiques au niveau de deux microphones (Mic 1, Mic 2), et génèrent des paramètres de différence entre les signaux acoustiques reçus au niveau de chacun des deux microphones (Mic 1, Mic 2). Ces paramètres de différence sont représentatifs de la différence relative du gain de signal entre des parties des signaux acoustiques reçus. Ces systèmes identifient des informations des signaux acoustiques comme de la parole non voisée lorsque les paramètres de différence dépassent un premier seuil, et ils identifient des informations des signaux acoustiques comme de la parole voisée lorsque les paramètres de différence dépassent un second seuil. D'autres modes de réalisation de ces systèmes comprennent des détecteurs (20) non acoustiques qui reçoivent des informations physiologiques destinées à aider à l'identification de la parole voisée.

Title: Piston pump
Inventor: KULTGEN RAYMOND J
IPC: F04B27/00
Filed: 2004-01-05
Abstract: A compact 180° opposed piston pump/compressor minimizes axial spacing between its pistons on the drive shaft and thereby reduces the shaking couple and noise from reciprocation. Each piston has its own eccentric element press-fit into the connecting rods so as not to occupy space between the pistons.   The shaking couple can be further reduced for pistons of different masses by selecting the mass of the cup retainers to compensate for the difference in overall piston masses. The pump also includes an improved cylinder sealing arrangement having a circumferential groove in an angled surface at the end of the cylinder. The pump also has a special cover and seal for closing the open neck of the pump crankcase and an improved multi-lobed valve stop. The pump further uses tubular transfer members for transferring intake and/or exhaust air into the crankcase and/or between valve heads.
