Title: Remote control for a plug-dropping head
Inventor: BAUGH JOHN LINDLEY
IPC: H04B10/10
Filed: 1994-05-23
Granted: 2005-01-11
Abstract: An apparatus and method of dropping a pumpdown plug or ball is revealed. The assembly can be integrally formed with a plug-dropping head or can be an auxiliary feature that is mounted to a plug-dropping head. The release mechanism is actuated by remote control, employing intrinsically saf e circuitry. The circuitry, along with its self-contained power source, actuat es a primary control member responsive to an input signal so as to allow component shifting for release of the pumpdown plug or ball. Multiple plug- droping heads can be stacked, each responsive to a discrete release signal. Actuation to drop the pumpdown ball or plug is accomplished even while t he components are rotating or are moving longitudinally. Using the apparatus and method of the present invention, personnel do not need to climb up in the derrick to actuate manual valves. There is additionally no need for a ri g floor-mounted control panel with hydraulic lines extending from the control panel to remotely located valves for plug or ball release.

Title: Controllable inverter power supply
Inventor: REYNOLDS JON O
IPC: B23K9/10
Filed: 1995-02-17
Granted: 1998-02-24
Abstract: In accordance with the present invention a power supply for providing an ac/dc output to a load is disclosed. The power supply includes a first source of dc power and an inverter that provides an ac output to the load.  A second source of dc power is provided and selectably connects the first and second sources of dc power in series with the load when the output current reverses.  In one embodiment the power sources are connected in series with every output current reversal.  The first source of dc power is controllable and the magnitude of the dc current is responsive to a current reference signal.  A control circuit provides the current reference signal, wherein the current reference signal is pulsed immediately prior to the ac output reversing polarity.  The first source of dc power source preferably includes a buck converter that is switched at a variable frequency, depending upon the desired output current.  In the event the user selects either an ac or dc electrode negative output a period of electrode positive dc energy is provided at start up to help establish the arc.

Granted: 2004-06-01
Abstract: A method and apparatus for drilling a curved bore are disclosed, wherein the apparatus includes a handle (20) and a removable cartridge (174) in which cutting bits (240) are disposed to produce the bore.  The handle includes a trigger (66, 66', 66") which the user squeezes toward a grip (24) of the handle to both energize a pneumatic motor (42) and to advance the opposed cutting bits in curved arcs at different rates. As the trigger is squeezed, a curved guide arm (234) conveying one of the cutting bits (240) is advanced more rapidly than the other curved guide arm (234), passing a median point is the bore and then being withdrawn as the other curved guide arm and cutting bit are advanced past the median point. Thus interference between the two cutting bits is avoided and a clean bore hole is produced. In addition, the removable cartridge (174) minimizes breakage of a flexible drive cable (238).

Abstract: In connection with a method and a device for the control of the optical alignment of two lightwaves in the course of a coherent superimposed reception, a spatial beam regulation is achieved in that the light of a local laser (5) is superimposed on the received light (1), that then the signal obtained in this manner is divided into two identical beam portions (1A, 1B) by means of a beam splitter (2) and that a respective error signal (14, 16) is generated from the two portions by means of a respective detector arrangement (3, 4), so that the two error signal portions result in a spatial error signal. The original data signal (15) is again obtained by the addition with the correct signs of the error signal portions.

Granted: 2003-05-06
Abstract: A services provision system, for use in providing information services over one or more communications networks, has a software infrastructure divided into domains (101, 103, 104, 106). Each domain has an intelligent software agent (102, 107, 109, 110) and this community of agents sits in a computing environment represented in each domain by a DPE kernel (105). The community of agents co-operates to provide service and service management functionality t o a user. At least one of the agents (102, 107, 109, 110) is reconfigurable to  change the functionality the system makes available. Reconfigurability is based on the use of a plurality of reusable software modules, the agent reconfiguring by selecting a new combination of modules. The software module s themselves incorporate rules, or policies, which determine process steps offered by the modules at run-time. These policies are external to the modul es and may be loaded at run-time, allowing dynamic modification to functionalit y of the system. The system as a whole offers functionality associated with using services, providing them and managing them and the reconfigurability allows it to offer the different types of functionality in an efficient way.  It also allows access control to functionality at different levels with particularly good security against fraudulent use.

Abstract: A radio-based, Electro-Pneumatic (EP) rail car braking system supports both End-of-Train (EOT) and Distributed Power Control (DPC) communication systems. The EP rail car braking system operates within existing frequency allocations and meets operational reliability needs by adopting a hybrid, two-band communications scheme. The EP rail car braking system uses a broadcast band for transmitting commands to all cars in the train. Selected cars spaced through the train are designated as repeaters, and a predetermined number of cars are assigned to each repeater for forming a group of cars that act as a Local Area Network (LAN). The cars in a group communicate with each other using a low power, spread spectrum band. In response to a command broadcast by a lead locomotive, cars in a group act on the command and transmit status information to their repeater car. The repeater car, in turn, sends back status messages to the lead locomotive on the broadcast band based on consolidation of data received from the cars in its group.

Abstract: Dans un service général de radio-communication par paquets (GPRS), les données sont codées dans des blocs (F) d'une longueur donnée qui comprennent une en-tête (1) et une section (2) de données. Un intrus peut interférer avec la communication GPRS en transmettant des copies non autorisées de messages transmis ou en envoyant de faux messages, et peut également interférer avec l'intégrité de la communication. On obtient une meilleure fiabilité de la communication GPRS en modifiant le bloc (F) utilisé sur une connexion GPRS de façon à ce que d'éventuelles copies supplémentaires des blocs puissent être découvertes. Ceci peut s'effectuer en ajoutant une zone supplémentaire d'information (3) à la section (2) de données d'un bloc (F) GPRS, le contenu de la zone étant modifié entre deux blocs (F). Le contenu de la zone d'informations supplémentaire (3) peut comprendre l'identité du bloc (F), l'identité temporaire de la liaison logique (TLLI) de la connexion, l'identité IMSI ou MSISDN de la station mobile ou une identité obtenue par un algorithme générant des nombres pseudo-aléatoires.

Abstract: Apparatus and process is provided for establishing values of the quality of gaseous hydrocarbons in gas extracted from mud while drilling. Two rare earth sensors, without a coating, are exposed to the extracted gas. The first sensor is pre-calibrated and outputs a signal proportional to the relative concentration of light hydrocarbons. The second sensor is pre-calibrated and outputs a signal proportional to the relative concentration of heavy hydrocarbons. Preferably a second sensor is selected which, during calibration outputs a signal which is also proportional to the relative concentration of light hydrocarbons in a light sample gas and outputs a signal which is inversely proportional to the relative concentration of heavy hydrocarbons in a heavy sample gas. The difference of the two signals is obtained and is compared to the first sensor signal as being indicative of the quality of any hydrocarbons present in the extracted gases.
