Title: Method and apparatus for measuring gas flow using boyle's law
Inventor: WOODWARD W STEPHEN
IPC: G01F1/34
Filed: 1993-02-23
Granted: 2002-09-24
Abstract: A gas flow meter uses the principle of Boyle's law to measure the gas flow rate along a path. Gas flows through a valve into a reservoir until the pressure is maximized in the volume. The valve then vents the reservoir to ambient while blocking the inlet path. The pressure at maximum and minimum values is measured by a pressure sensor and used to generate the flow rate signal. An enlarged volume in the inlet path limits the pressure rise during the exhaust phase of the measurement cycle.

Title: High pressure soil disintegrating and excavation system using suction to remove water and particles
Inventor: KLAPTCHUK PETER
IPC: E21B7/18
Filed: 1993-08-24
Granted: 1996-08-06
Abstract: An excavation technique involves producing a high pressure jet of water having the pressure greater than 2000 psi so that the jet is communicated through a wand to a nozzle which causes the jet to rotate about a longitudinal axis of the nozzle. A vacuum duct can be moved to a position adjacent the nozzle and generates a very high airflow of at least 2000 cfm at a vacuum greater than 10 inches mercury. These parameters combine to provide an efficient and economic excavation system by which the soil impacted by the jet is broken into soil pieces and particles which are drawn away in relatively dry form for storage within an extraction tank.

Abstract: Methods of draw-down and build-up testing on existing production  wells  are  disclosed.    The  testing  may  be accomplished without removing the production tubing string from the well.  The production of the well is shut down and then a  coiled tubing test  string  is run down  into the production tubing string.   The coiled tubing test string includes a coiled tubing string, a tester valve carried by the coiled tubing string, and a test packer carried by the coiled tubing string.   The test packer is set within one of the casing bore and the production tubing bore above perforations which communicate the casing bore with a subsurface formation.          Draw-down and build-up testing of the subsurface formation can then be accomplished by opening and closing the tester valve to selectively flow well fluid up through the coiled tubing string or shut in the coiled tubing string.  After the draw-down/build-up testing is completed, the coiled tubing test string is removed from the well and production of the well is resumed  up  through  the  production  tubing  bore  of  the production tubing string.  Optionally, the coiled tubing test string may carry a perforating gun to perforate a new zone of the well which may then be tested.

Abstract: A friction clutch (20) coupling an engine (10) and a gear transmission (30) of a vehicle is controlled by a microprocessor based circuit using logic which defines operating modes according to engine (10) and clutch (20) conditions.  During the time of clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal  (11).          This  avoids  engine  overspeeding  which  results  from generating high torque before sufficient clutch capacity has been achieved.  The control signal is developed as a function  of the pedal  (11)  position under  control  of throttle logic which,  in turn,  is dependent on clutch operating modes defined by the clutch logic.  The clutch operating  modes  are  four  modes  for  automatic  clutch operation comprising touch point (81) approach mode which prohibits a throttle signal during initial clutch movement, creep mode or startup mode after touch point 81 occurs, and lockup mode for completing clutch closing when low clutch slip is attained.  A non-automatic mode is entered before the accelerator pedal (11) is depressed or when engine (10) stall conditions are detected.

Abstract: A pneumatically damped vehicle suspension system. The suspension system provides damping which is load-dependent, i.e., the amount of damping varies in approximate proportion to the load supported by the suspension system, thereby maintaining a nearly constant fraction of critical damping over the normal range of operating loads. The damping provided by the system is also frequency-dependent, a characteristic not achievable with hydraulic dampers. Two independent damping circuits provide maximum damping at the suspension's two resonant frequencies, or modes of vibration--the bounce mode and the axle-hop mode. Relatively little damping is provided at other frequencies, resulting in improved isolation of road inputs.

Title: Packaging system for dispensing cartridge for volatiles
Inventor: GORDON ANDREW D
IPC: B65D77/04
Filed: 1994-05-03
Granted: 1999-11-30
Abstract: ABSTRACT OF THE DISCLOSURE   A protective package system for containing a delivery cartridge for volatile substances such as fragrances, deodorizers, air fresheners and the like, wherein the cartridge includes an active ingredient reservoir with a permeable surface through which substances may move from the reservoir. The packaging system preferably includes a cartridge container having a storage area for receiving the cartridge, and a substantially open top with an outer periphery. A peelable lid is sealingly attached to the outer periphery of the container, and a blotter is attached to at least a portion of the inner surface of the peelable lid and preferably spaced inwardly from the outer edge of the lid so as not to interfere with the sealing attachment of the lid to the container. The blotter is thereby held in face-to-face contact with the permeable surface of the cartridge within the packaging system when the lid is in sealed condition and remains captively attached to the lid upon opening of the packaging system. In a preferred embodiment, the container is further provided with a blotter recess to facilitate preliminary alignment of the blotter with the permeable membrane of a cartridge held therewithin, and to facilitate captive attachment of the blotter to the inner surface of the peelable lid during sealing procedures. In this way, the blotter can be independently placed within an open container after the volatile cartridge has been loaded with its permeable membrane facing outwardly through the open top. Manufacturing procedures are thereby simplified, yet the blotter will be captively attached to the peelable lid to minimize potential for contact with the user upon opening.
