Title: Rechauffeur visqueux a capacite variable
Inventor: BAN TAKASHI
IPC: B60H1/22
Filed: 1996-09-05
Granted: 2000-07-18
Abstract: Appareil de chauffage à fluide visqueux du type à puissance variable qui peut effectuer une régulation de puissance de façon fiable et qui peut maintenir l efficacité du fluide visqueux à produire de la chaleur, même après une longue période de service.  Par exemple, son boîtier arrière 6 comporte une chambre de régulation 9 qui communique avec le centre d'une chambre productrice de chaleur 7 et qui a un volume intérieur libre capable de se dilater et de se contracter.  Lorsqu'un rotor 14 tourne, une huile de silicone, gardée dans la chambre productrice de chaleur 7, dilate le volume intérieur libre de la chambre de régulation 9 par l'effet Weissenberg de la diminution de puissance.  Le chauffage est ainsi diminué, parce que l'huile de silicone, gardée dans la chambre productrice de chaleur 7, est recueillie dans la chambre de régulation 9.

Title: Multiple product dispensing system including dispenser for forming use solution from solid chemical compositions
Inventor: BOCHE DANIEL K
IPC: B01F3/08
Filed: 1995-11-20
Granted: 2004-04-27
Abstract: A multiple product dispensing system (100) includes a plurality of use solution dispensers (10a, 10b, 10c) and a controller (110) for selecting one of the dispensers (10a, 10b, 10c) according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser (10a, 10b, 10c) dispenses a controlled concentration of use solution using a diluent delivery apparatus (13) that delivers a diluent to form a liquid concentrate from a solid chemical composition (22), and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer (24) reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system (100) to dispense a use solution of carefully controlled concentration, and the controller (110) will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator. Therefore, the likelihood of operator error occurring is greatly reduced by the automatic selection of the proper dispenser (10a, 10b, 10c) and the control over use solution concentration.

Abstract: A launch aircraft (30) launches a bomb (10) at a target (36) and uses a rada r (31) to transmit a predefined waveform (35) at the bomb (10) and target (36). The bomb (10) incorporates a transponder that frequenc y shifts the transmitted waveform and illuminates the target with a shifted waveform (33) having a null at the center of its beam pattern . The initially transmitted waveform and frequency shifted waveform are reflected from the target and are received by the radar. The received signals are processed to generate a correction signal (32) that is a function of the offset between the null of the frequency shifted waveform and the target location. The correction signal is transmitted to the bomb and is processed therein to correct the flight path of the bomb toward the target.

Title: Method of obtaining improved geophysical information about earth formations
Inventor: REIMERS NILS
IPC: E21B47/12
Filed: 1997-10-09
Granted: 2004-02-24
Abstract: The present invention provides a method for forming wellbores. In one method, one or more wellbores are drilled along preplanned paths based in part upon seismic surveys performed from the surface. An acoustic transmitter conveyed in such wellbores transmits acoustic signals at one or more frequencies within a range of frequencies at a plurality of spaced locations. A plurality of substantially serially spaced receivers in the wellbores and/or at surface receive signals reflected by the subsurface formations. The sensors may be permanently installed in the boreholes and could be fiber optic devices. The receiver signals are processed by conventional geophysical processing methods to obtain information about the subsurface formations. This information is utilized to update any prior seismographs to obtain higher resolution seismographs. The improved seismographs are then used to determine the profiles of the production wellbores to be drilled. Borehole seismic imaging may then be used to further improve the seismographs and to plan future wellbores. Cross-well tomography may be utilized to further update the seismographs to manage the reservoirs. The permanently installed sensors may also be used to monitor the progress of fracturing in nearby wells and thereby provide the necessary information for controlling fracturing operations.
