Title: Disintegration of baled crop materials
Inventor: BUSSIERE RAYMOND
IPC: A01D87/12
Filed: 1995-10-16
Granted: 2005-02-15
Abstract: Apparatus for disintegrating bales comprises a hopper with vertical end walls and two side walls which converge inwardly and downwardly to a part cylindrical base portion extending longitudinally of the hopper. The upper face of the hopper defined at the top of the side and end walls is open to receive a bale dumped into the hopper. In the hopper is provided a pair of parallel rollers for supporting an rotating the bale when in the hopper. In the base portion is provided a flail roller which rotates about its axis grasping material and throwing it out of an exit slot longitudinally of the hopper at the base of the hopper. Rectangular bales are loaded into the hopper by an inclined ramp with a chain conveyor on the ramp, the ramp having a loading position in which it is inclined from a forward edge adjacent one side wall to a rear edge at the ground for pushing under the rectangular bale by which the bale is carried up the ramp to sit on the ramp. The ramp can then be raised to a discharge position in which it is inclined upwardly and rearwardly from the top edge of the end wall so the bale can be forced downwardly and forwardly into the hopper even though the bale may have a length greater than that of the hopper. To accommodate different types of bale, also the grid bars over the flail roller are commonly adjustable so that their height from the flail roller is adjusted by raising and lowering one end of the grid bars on a shaft extending along the length of the hopper and operable by a lever at one end.

Title: Systeme de suppression de parasites dans les transmissions de retour en television par cable
Inventor: HIMAYAT NAGEEN
IPC: H04N7/173

Granted: 2000-08-22
Abstract: Un système d'annulation d'interférences pour un système de télévision par câble réduit la présence des interférences à bande étroite indésirables qui perturbent la transmission de signaux de retour. Le système d'annulation acquiert tout d'abord un signal de référence contenant des composantes en lien avec les interférences présentes dans le signal de retour. Le signal de référence est traité afin d'en dériver des estimations des composantes d'interférence apparaissant dans le signal de retour et un signal d'annulation est généré. Le signal d'annulation d'interférences est ensuite combiné au signal de retour, en réduisant ainsi les composantes d'interférence qui y sont présentes. Le système d'annulation d'interférences est déployé à une extrémité de tête du système de télévision par câble et des techniques d'accès multiple par répartition temporelle (TDMA) sont mises en uvre pour la transmission de retour. Le signal de référence est dérivé par surveillance de tranches de temps au sein d'une trame TDMA contenant des données de transmission prédéterminées. Les données prédéterminées correspondent de préférence à l'absence de données se soldant en une tranche de temps inactive. Ces tranches de temps peuvent être temporairement inactives, ou bien être laissées délibérément inutilisées pour fournir une fenêtre à une composante « bruit seul » du signal de trajet de retour. Le signal ainsi obtenu passe par le même stade de traitement RF que le signal de retour composite puis est échantillonné et numérisé. Ensuite, des techniques d'estimation de spectre sont appliquées aux échantillons du signal pour détermine les fréquences des signaux d'interférence. Une fois qu'une estimation des fréquences d'interférence a été obtenue à partir du spectre, il est possible de synthétiser le signal de référence comprenant les mêmes fréquences.

Abstract: A recording/reproducing apparatus (e.g., VTR) includes capability to exchange information with a storage apparatus such as a memory card mounted on a recording medium assembly (e.g., cassette). When the cassette is inserted into a compartment in the compartment in a VTR, a switch in the VTR is pushed by the case of the cassette, detecting the insertion of the cassette into the compartment. At that time, a signal indicating the insertion of the cassette into the compartment is supplied to a microcomputer from the switch. Notified by the signal, the microcomputer issues a command to a reader/writer, requesting the reader/writer to read out information pertaining to data recorded on the cassette from the memory card mounted on the cassette for recording the data through an antenna. With the cassette located outside the compartment, on the other hand, the microcomputer issues a command to a reader/writer, requesting the reader/writer to read out the information from the memory card through another antenna.

Abstract: In this invention, drill pipe or tubing is attached to a sampling tool that is suspended in a borehole. A wireline cable also connects the tool to surface equipment and establishes electrical communication between the tool and the surface equipment. A valve located in the docking head assembly controls fluid flow between the borehole and the drill pipe through a port located within the drill pipe assembly which is opened and closed as required. During operations, the tool takes fluid samples from the formation and analyzes them for contamination levels. Unacceptable fluid is pumped or flowed through the tool via a flowline and into the drill pipe where it is stored until it is disposed of at the surface. Once the flowing fluid reaches acceptable levels of contamination, this fluid is pumped or flowed into a sample chamber(s) in the tool. Once sampling is completed the contaminated fluid is forced to the surface by opening the port and pumping a different fluid down the borehole annulus, through the port and into the tool below the contaminated fluid and thereby filling the drill pipe and forcing the contaminated fluid up the drill pipe and to the surface, instead of discarding the fluid into the borehole or storing the fluid in the tool. This invention allows for larger amount s of fluid to be retrieved from the formation which results in cleaner fluid samples and better information about the formation. Moreover the nature of the pressure data acquired both during periods of flow and shut-in can be used to deduce formation permeability and permeability anisotropy.

Title: Ball point fluid-assisted electrocautery device
Inventor: HOEY MICHAEL F
IPC: A61B18/08
Filed: 1996-10-02
Granted: 2002-04-09
Abstract: An electrocautery device is disclosed. In accordance with one aspect of the invention, the electrocautery electrode/tip is provided with a hollow, conductive tube terminating at its distal end in a ball point type tip. Fluid, preferably conductive fluid, is applied to the proximal end of the hollow electrode/tip, and expelled from the distal end thereof during electrocautery.  The ball point distal tip allows the distal tip to be directly applied to the tissue and "rolled" or slid along the tissue. This allows the distal tip to be moved across the tissue without dragging or snagging on the tissue. In addition, the conductive fluid expelled from the distal tip further lubricates the distal tip as it moves across the tissue. If conductive fluid is used, the conductive fluid emanating from the electrode/tip conducts the RF  electrocautery energy away from the distal tip so that it is primarily the fluid, rather than the distal tip that actually accomplishes the cauterizing of tissue. That is, the fluide serves as a "virtual" electrocautery electrode.  Since it is the fluid, rather than the distal tip that cauterizes, coagulates and ablates, no burns or perforations are made to the tissue, reducing the amount of debris at the site. Also, the flow of fluid through the electrode/tip tends to keep the distal tip clean and cool.

Abstract: Multiported register files are employed to implement the input delays necessary for finite impulse response (FIR) filter operation. A multiported register file is a memory, typically small, with at least one read port and one write port. Data written into the multiported register file may be read out therefrom in anydesired order. The multiported register file may have additional output ports from which the data stored therein may be read out, also in any desired order, and independent from the order of any other output port. At least one output of eachmultiported register file is coupled to the input of the next stage of the FIR filter, if any. In addition, each multiported register file feeds data from one output to the multiply-add portion of its associated stage of the FIR filter. When the introduction of at least one sample delay for a particular sample is necessary, the multiported register file storing that sample is operated to supply, as an output, data that was previously stored therein, regardless of any data currently being supplied to it as input. In contrast, when no sample delay is required for a particular sample to reach a particular multiported register file, the multiported register files in the path of that sample are operated in a lookthrough mode. The read and write addresses, as well as the write enable signals for each multiported register file may be supplied in apipelined manner.
