Title: Method and device for dopler measuring of radial speed
Inventor: VATSOV MILCHO D
IPC: G01P3/36
Filed: 1989-10-10
Abstract: The method and the device apply to the astrophysics, space equipment and the spectral analysis. They enhance the measurement accuracy in real time. The method includes the spectral decomposition of the received signal, recording the intensity of the decomposed spectrum, measurement of the Doppler deviation of an emission line towards a given reference and determination of the radial velocity. Before the spectral decomposition takes place the examined emission is frequency modulated and the Doppler deviation is reduced to the measurement of a phase difference between the modulated signal and a signal proportional to the intensity of the emission near the chosen emission line of the examined spectrum. The device consists of an optically connected telescope, input slot (1), collimator (2), dispersing system (3) and intensity recorder (4). Between the collimator (2) and the dispersing system (3)a frequency electro-optical modulator is placed (5), connected to a modulating voltage supply (6). The recorder (4) is a photo electronic receiver (7) optically and mechanically fixed with a movable measurement optical slot (8). The output of the receiver (7) is connected through a peak detector (9) and a shaper (10) to the measuring input of a phase meter (11) which reference input is connected to the modulating voltage supply (6) and its output to a computational block (12).<IMAGE>

Abstract: L'invention concerne un système de construction de pompes, de compresseurs et de moteurs comprenant une chambre rotative et des pistons opposés entraînés dans le même sens, à des vitesses alternativement variables, par l'intermédiaire d'un mécanisme approprié permettant de faire varier alternativement lesdites vitesses dans une structure fixe ouverte ou fermée. Ledit nouveau système est caractérisé par la chambre qui n'est pas fondamentalement fixe. Au contraire, ladite chambre est rotative, de préférence, formée de deux demi-chambres rotatives dotées chacune d'au moins un dispositif de déplacement ou d'un piston fermant la demi-chambre à laquelle il est relié et pénétrant par coulissement dans le creux de l'autre demi-chambre, créant ainsi au moins deux compartiments dont le volume varie alternativement. Les axes de chaque demi-chambre rotative se déplacent dans une structure fixe qui les supporte. Cette structure peut être ouverte ou contenir un compartiment hermétiquement clos. Dans l'une de ses versions, la structure porte une bague dotée d'ouvertures d'admission et d'évacuation de fluides. Chaque demi-chambre rotative, disposée de part et d'autre de cette bague, fonctionne de façon à fermer une chambre principale. Au moins un piston ou un dispositif de déplacement fixé à chaque demi-chambre ferme hermétiquement une partie de celle-ci et est introduit par glissement dans l'autre demi-chambre rotative, divisant ainsi ladite chambre en au moins deux compartiments. Lorsque ces pistons sont déplacés à l'aide d'un mécanisme approprié (bras coulissants, engrenage excentrique, elliptique ou planétaire, etc.), leur volume varie alternativement.

Filed: 1990-06-08
Abstract: CONSERVATION TILLAGE IMPLEMENT CONVERTIBLE              FOR END TRANSPORT           A large tillage implement provided with hinging wing sections is adapted for end towing rath-er than wing-up folding transport,  The hitch which is normally centered at the front of the machine may be swung into a folded condition parallel with the longitudinal axis of the frame and overlying the front portion thereof to protect the hitch coupling to the vehicle outwardly beyond the end of the frame. A front row of tillage shanks can be selectively raised or lowered as desired while leaving the rear row of shanks at their normal elevations for ground working, and a special frame design enables the rear ground wheels of the frame to be positioned in close fore-and-aft proximity to the rear tillage shanks to provide more uniform depth of penetration of the shanks as rises and falls in the ground terrain are encountered.  Improved trash flow and reduced trash and residue accumulation are achieved through strate-gic ground wheel location relative to the tillage shanks and streamlined wheel arm designs associated with the wheel assemblies.

Title: Bi-phase code generation and amplification circuit for microwave and millimeter-wave frequencies
Inventor: ROBERTSON RALSTON S JR
IPC: H04L27/20
Filed: 1990-07-23
Abstract: ABSTRACT OF THE DISCLOSURE      A system for bi-phase code generation with signal amplification is disclosed in which a digital signal applied to the tuning voltage input of an injection locked voltage controlled oscillator (VCO) is used to produce a corresponding phase modulated output signal at the locked frequency of the VCO.  The invention includes a voltage controlled oscillator (VCO) 12, a tuning voltage source 14, a three-port circulator 20, and a locking frequency source 28.  The output signal from the VCO 18 is applied to a second input port of the three-port circulator 22, while a locking frequency signal is applied to a first input port of the three-port circulator 24.  This arrangement causes the frequency of the output signal produced by the VCO 18 to be locked to the frequency of the signal injected into the first port of the three-port circulator.  As the output frequency of the VCO 18 is locked to the frequency of the injected signal, a change in the tuning voltage applied to the VCO 16 results in a corresponding change in the phase of the output signal produced by the VCO 18, instead of a change in frequency.  This allows the final output signal of the injection locked VCO 18 to be phase modulated in accordance  with  the  applied  tuning  voltages. Furthermore, the injected signal is amplified by the associated gain produced by the VCO.  Consequently, both signal amplification and continuous phase adjustability is achieved with this invention.

Abstract: METHOD OF FORMING IMAGES AND MATERIALS THEREFOR        Abstract An aggregated-Group Ib metal colloid is prepared, which may be used to form stable color-differentiated images, by the selective application of thermal energy thereto.  The metal aggregates, when exposed to thermal energy, revert either to the unaggregated metal or to an aggregate of lesser dimension.  This change induces a color change in the material, which is clearly visible against those areas not so exposed.  The metal aggregates, when dispersed in a polymeric matrix, are stable in the absence of heat.
