Granted: 1990-12-10
Abstract: A combination composed of a conduit for conveying a fluid medium along a linear path under very high pressure and a choke disposed in the conduit, the conduit having an inner wall and the choke being composed of a restrictor having a restrictor opening which is constricted relative to the cross section of the conduit and a movable needle mounted for movement in the direction of the linear path for constricting or closing the restrictor opening. The conduit is made of a material capable of withstanding the high pressures exerted on the inner wall of the conduit by the flowing medium and the choke is made of a very hard and brittle material which is resistant to wear. The choke further includes a central insert member having an outer tubular part fastened to the inner wall of the conduit, an inner part supporting the needle within the conduit so that fluid medium flowing through the conduit flows around the needle, and a member connecting the inner part to the outer part. The needle is supported by the inner part for movement relative to the inner part parallel to the linear path. The choke further includes a hydraulic drive unit supported by the inner part and forming a unit with the needle. The central insert member is configured and fastened to the inner wall of the conduit so as to offer only slight resistance to flow of the fluid medium past the central insert member.

Granted: 1999-06-29
Abstract: Radio  frequency  bridge  techniques  are  used  to parameterize  the  complex  dielectric  properties  of  solids, liquids,  gases and mixtures thereof.   This parameterization is performed  in an electrically  isolated,  physically  open structure which allows continuous or batch monitoring of the materials and their mixtures.   A method and apparatus are provided  for  measuring  the  composition  of  multicomponent process streams flowing in pipes or ducts.   The method uses the pipe in which the mixture flows as a waveguide in which propagating radio frequency electromagnetic energy is induced through  dielectric   loaded  apertures.     The  dielectric measurement  is performed in an electrically isolated,  flow through test section which induces constructive or destructive interference  patterns  at  characteristic  frequencies.    The characteristic  frequency determines the dielectric  constant of the mixture.   The dielectric properties are used in turn to determine mixture composition.   A density measurement is also provided for three component streams such as oil, water, and gas.   Temperature and pressure measurements are made to correct  for temperature and pressure induced variations  in calibrated component impedance and density values.

Abstract: ABSTRACT OF THE DISCLOSURE     A logic synthesis network for efficiently combining respective bit pairs of first and  second operands to produce respective sum bits and a carry bit associated with the most significant sum bit.   A dummy generator receives the respective bit pairs and generates first and second dummy sum signals, and first and second pairs of dummy  carry  signals.   A  first  dummy  selector  chain selects the appropriate dummy sum and carry signals of all the bits other than the least significant bit, as a function of the state of the first pair of dummy carry signals generated for the least significant bit pair.  A second dummy select chain selects the appropriate dummy sum and carry signals for all the bit pairs other than the least signficant bit pair, as a function of the state of the second pair of dummy carry signals generated for the   least   significant  bit  pair.    Sum  generators associated with each bit pair choose between the selected dummy sum signals from the first and second dummy select chains  in  accordance with  the  state  of  the  carry-in signal associated with the least significant bit pair.          Carry generators associated with each bit pair choose between the first and second pairs of dummy carry signals at the ends of the first and second dummy select chains, again in accordance with the state of the carry-in signal associated with the least significant bit pair.

Title: Method of operation of air cleaner used in motor vehicle
Inventor: TAKASHIMA YOSHINORI
IPC: H02J7/00
Filed: 1990-06-05
Granted: 1998-07-14
Abstract: Method of operation of an air cleaner used in a motor  vehicle, comprises  the steps of:   intermittently turning off a blower motor of the air cleaner at a given interval; detecting ripple components included in an output voltage developed by a dynamo driven by an engine of the motor vehicle by detecting the output voltage between dc power supply lines connected from the dynamo to the air cleaner; and maintaining turn off condition of the blower motor when the ripple component is lower than a given level during intermittently turning off the blower motor.  When the engine is stopped, during the on interval of the blower motor, stoppage of the engine cannot be detected by watching the  ripple  components  included  in  power  supply  lines. However,  during  the  following  intermittent  turning  off interval, stop of the engine can be detected because the ripple component due to operation of the blower motor is not developed.  Therefore, the blower does not continue to run after stopping of the engine, so that power stored in the battery is saved.

Granted: 1997-02-25
Abstract: A current source inverter power supply for an ozone generator which results in improved efficiency and reliability in operation of such generators has an AC/DC converter coupled through a large inductance to a DC/AC inverter that, in turn, is coupled at its output to the primary of a high voltage transformer. Such transformer has an air gap in its core to supply the electrical characteristics necessary for resonance with the load which is capacitive in nature. Thyristors in the inverter are naturally commutated so the switching frequency is close to, but slightly above, the natural resonant frequency of the inverter/transformer/ozone generator circuit.

Title: Optical system for measuring linear or angular displacements
Inventor: GREGO GIORGIO
IPC: G01D5/26
Filed: 1990-06-27
Granted: 1993-04-06
Abstract: ABSTRACT     An optical system for measuring linear or angular displacements uses a monochromatic radiation source and an acousto-optic modulator, which acts as a Bragg modulator and is driven at a frequency which is caused periodically to vary.  The modulator emits a first beam having the same wavelength  as  the  source  and  a  second  beam,  whose wavelength and emission direction vary with the modulating frequency.  The second beam is collimated.  For measuring angular displacements, the collimated beam is recombined with the first beam after traversing a plate with a plane parallel faces, to which plate the rotation of a moving detent is transmitted, and a photodetector generates a beat signal whose frequency depends on the angular position of the plate.   For measuring linear displacements, the two beams are directly sent to a detector moving with the moving element.

Title: Circuit breaker with adjustable low magnetic trip
Inventor: SHEA JOHN JOSEPH
IPC: H01H71/74
Filed: 1990-09-12
Granted: 1999-12-14
Abstract: A circuit breaker has a magnetic trip assembly which can be adjusted to trip the breaker for low level overcurrents in the range of five to ten times rated current. The magnet trip includes for each pole of the breaker a helical torsion spring having one torsion arm which biases an armature against an adjusting bar to form a gap between the armature and a stationary magnetic structure in which magnetic flux strong enough to attract the armature and trip the breaker is induced by overcurrent. A second torsion arm of the spring has a first portion which bears against and slides along a pivot member carried by the adjusting bar to adjust the bias force applied to the armature by a given amount per unit travel of the adjusting bar over a low trip current portion of the range of travel of the adjusting bar. A second terminal portion of the second torsion arm of the spring extending at an angle from the first portion engages and slides along the pivot member on the adjusting bar to provide a greater change of bias force per unit travel of the adjusting bar at the higher trip current settings. Movement of the adjusting bar adjusts the spring bias for all poles of a multiphase circuit breaker simultaneously. The gaps between the armatures and the fixed magnetic structures of all the poles can also be adjusted by caroming surfaces on the adjusting bar against which the springs bias the armatures. In an alternative embodiment, the gaps can be adjusted separately for each pole by screws carried by the adjusting bar which bear against ramming surfaces formed by twisted tabs on the armatures.
