Title: Cryogenic air separation process and apparatus
Inventor: SWEENEY PAUL A
IPC: F25J3/04
Filed: 1993-10-20
Granted: 1997-03-18
Abstract: A cryogenic air separation process and method in which air is cooled and after compression and purification then rectified in a rectification column  to  produce  an  oxygen  rich  liquid.   An  argon-oxygen  stream containing liquid lean in nitrogen is separated to form oxygen and argon streams.  Argon vapor is condensed to supply reflux to the argon column. An oxygen rich  liquid stream is expanded to a pressure at which the oxygen rich  liquid is at or below the condensation temperature of the argon vapor and is then vaporized against condensing the argon vapor. The vaporized  oxygen  rich  liquid  is then introduced into a nitrogen stripper column and nitrogen is stripped therefrom by a stripper gas to produce  the  argon-oxygen  liquid  which  is  introduced  into  the  argon column.   The  nitrogen  stripper  column  is  regulated  to operate  at  a predetermined pressure range so that the entry level  at which oxygen enters the nitrogen stripper column has a pressure level no greater than the pressure of the oxygen rich liquid after expansion.  Argon is removed from the top of the argon column as a product.  The process and apparatus can be operated to produce high purity argon vapor or liquid very lean in nitrogen and oxygen with the use of trays and/or structured packing as liquid contacting mass transfer elements in the columns.  Additionally, high purity oxygen and nitrogen products can also be produced by such process and apparatus.

Abstract: Components such as pyroelectric sensors which are particularly sensitive to piezoelectric effects and can be adversely affected as a result by any mechanical stress or vibration are described. These adverse effects may be controlled by inserting a flexible silicone sheet (42) between the chip (10) bearing the pyroelectric film and the bottom of the package (30) so that it absorbs package distorsion without passing it on to the chip. Means are provided to enable connecting leads (34) to be ultrasonically welded even though the flexible sheet is present. The chip is preferably attached to a metallized ceramic wafer (40), and abutments (44) are preferably provided at the package bottom to limit compression of the flexible sheet (42) during the welding operation.

Filed: 1992-02-03
Granted: 2001-12-25
Abstract: Methods for conducting controlled environment electrotransport are described.  The methods generally concern control of the ionic environment of the active electrode reservoir, in an electrotransport system. This control may be utilized, for example, to maintain a constant extraneous ion presence, such as pH. It may also be applied in a preferred manner to maintain selected con-trol over the delivery rate of a target species, in time, in the presence of extraneous ions. Apparatus usable to provide for con-trolled environment electrotransport are also described. In general the apparatus comprises an electrotransport system (5) includ-ing an active electrode reservoir (6) having therein both a primary electrode arrangement (30) and a secondary electrode arrange-ment (50), with a control arrangement (40) for selected operation of both. The secondary electrode arrangement (50), being operated different from the primary electrode arrangement (30), is selected for operation to selectively enhance or otherwise mod-ify ion presence in the active electrode reservoir (6), to achieve application of the general methods described. The apparatus may include a sensor means (60) therein, for use as feedback to a control system (40) during operation. Methods and systems involv-ing diffusion type delivery are also described.

Abstract: Method for automatically adapting and configuring the speed of a terminal adapter to the rate 56Kbps or 64Kbps which is used by a calling adapter. After the sending in the called terminal adapter of the CONNECT message which is sent to the ISDN NETWORK in accordance with CCITT Q.931 Recommendations,  the called TA is initialized to a rate of 64 Kbps and then continuously transmits an alignment pattern ALL_ONES while starting a first timing process (T1). This first timing process will cause the called TA to switch to a 56Kbps speed if the 64 Kbps validation process does not succeed.  The  method  then  involves  the  step  of  checking  the reception of a ALL_ZEROS pattern coming from said calling adapter (20) before the end of said first predetermined period (T1). If this case, a 64 Kbps validation process will be performed which comprises the checking whether a ALL_ONES pattern is received within a second period  (T2),  in which case the 64 Kbps rate configuration will be validated. On the contrary, if the ALL_ZEROS pattern is not received at the end of the first period (T1), a 56 Kbps rate validation process is initiated which is based on the detection of a so-called 56 Kbps pattern within the data flow. The 56 Kbps pattern is defined as being a number of n bytes with the first bit of every byte being set to a one. Additionally, the 64Kbps validation process involves the checking of the continuous receiving of said ALL_ZEROS pattern during said first period (T1) as long as the ALL_ONES pattern is not yet received, and at the end of said first period (T1) validating the 64Kbps rate.

Abstract: The present invention includes an arrow guide and bow sight adaptable to right-handed or left-handed archery bows. The arrow guide including a vertical support wheel with a V-shaped groove running along its circumference in which an arrow may rest when shooting. This wheel is designed spin freely on a support rod, reducing friction imparted to the arrow shaft, thus increasing the accuracy, speed, and power of the archer's shot . For lateral support, two horizontal wheels are positioned to either side of the vertical support wheel to prevent the arrow from falling off of the vertical support wheel when the bow is jarred or when the bow string is quickly drawn back. Also connected to the arrow guide device is a sighting device comprising a multiplicity of sight pins and a vertical cross-hair. The sight pins are vertically adjustable to be calibrated to assorted ranges, and both the pins and the cross-hair are horizontally adjustable to account for windage.

Title: Integrated modulator and turbine-generator for a measurement while drilling tool
Inventor: LERNER DANIEL
IPC: E21B47/18
Filed: 1995-04-21
Granted: 2007-11-27
Abstract: An integrated modulator and turbine-generator includes a turbine impeller which is directly coupled by a drive shaft to a modulator rotor downstream from the impeller. The modulator rotor is further coupled by a drive shaft and a gear train to a three phase alternator downstream of the modulator rotor. The modulator stator blades are arranged downstream of and adjacent to the modulator rotor and the alternator is provided with a Hall effect tachometer. The turbine impeller directly drives the modulator rotor and the alternator generates power. The speed of rotation of the modulator rotor is adjusted by reference to the speed of rotation of the alternator as indicated by the tachometer and to a reference frequency. A control circuit including an electromagnetic braking circuit coupled to the tachometer and the stator windings of the alternator stabilizes the alternator speed and thus the rotor speed and modulates the rotor to obtain the desired frequency of the mudborne pressure wave by selectively shorting the stator windings of the alternator. During periods when braking is not applied, the alternator generates power for control and sensor electronics.
