Patent EP-0402527-A2 (EP)
Inventor: CLAREN THEO
IPC: G01B11/06
Filed: 1989-12-12
Abstract: The invention relates to a device for measuring at a distance the thickness d of a layer of a non-conducting material (2), which is arranged on a carrier material (1), by means of a sensor (3). In order to achieve, on the one hand, that the accuracy of the layer thickness measurement is largely independent of the particular position of the sensor (3) and, on the other hand, that the disadvantages of ultrasonic measuring instruments or of procedures which employ ionising radiation do not occur, it is proposed that the sensor (3) contains two ranging sensors (31, 32; 33). In this case, the first ranging sensor (31, 32) measures signals which are characteristic of the range a1 between the sensor (3) and the surface, facing the sensor (3), of the non-conducting layer (2). By contrast, the second ranging sensor (33) measures signals which are characteristic of the range a2 between the sensor (3) and the surface, facing the sensor (3), of the carrier material (1). The layer thickness d is then yielded by the relationship d = a2 - a1. It is advantageous to employ as first sensor (31, 32) an optical, and as second sensor (33) an eddy-current sensor, it being necessary in the case of the employment of the eddy-current sensor for the carrier material (1) to be an electrically conducting material. <IMAGE>

Abstract: In measurement method of dispersion characteristics of an optical fiber 4, a laser for measurement 2′ connected to one end of the fiber 4 and variable in output light wavelength and an oscillator 1 for modulating a measurement light signal L1 sent out from the laser 2′ are provided. The modulation frequency of the output from the osscillator 1 is used as an reference electric signal Sa. A measuring light signal L2 obtained through the modulator 8 and transmitted through the fiber 4 is converted into an measuring electric signal D. And the characteristics is measured from the phase difference between the reference electric signal Sb and the measuring electric signal D, wherein an external modulator 8, an optical divider 9 and a monitoring section 20 are provided. The modulator 8 modulates the measuring light signal L1 sent out from the laser 2′ and having a narrow spectral linewidth. The divider 9 divides the output light signal L2 from the modulator 8, at a prescribed ratio. The measuring light signal L2 obtained through the modulator 8 is multiplexed with output light   signal from a laser for monitoring 10 by the section 20 to generate a beat to measure the oscillation wavelength of the laser for measurement 2′ through optical heterodyne detection. And the characteristics is measured while the result of the measurement of the oscillation wavelength is compared with that of the measurement of the phase difference.

Abstract: In a control rod construction for moderating and controlling a reaction of a nuclear reactor, a control rod structure is disclosed in which hafnium (46) is friction-welded to stainless steel (44). Typically, the control rod is confined for movement (52) axially along its length into and out of the reactor. The hafnium is surrounded in the control rod structure by a sheath of stainless steel (40) to inhibit movement relative to the control rod structure other than in the axial direction of control rod movement. The weld is thus stressed only in either tension or compression due to dynamic loading occur­ring from control rod movement. The stainless steel to which the hafnium is welded is in turn convention­ally welded (49) or mechanically connected to the remaining steel components of the control rod. There results a secure control rod structure having welded hafnium that can withstand the dynamic loadings of fast insertion of control rods such as those loadings which commonly occur under rapid control rod accelera­tion and deceleration due to SCRAM of a reactor.

Abstract: A crystallographic observation apparatus for the observation of behavior of crystals under pressure and for the measurement of the crystallization pressure and pressure of fusion of substances. The apparatus comprises a pressure chamber having a cavity and provided with a transparent observation window or windows, a pressurizing device for pressurizing the cavity of the pressure vessel, and small, entirely or partly transparent, entirely or partly elastic sample containing means for containing a sample, provided within the cavity of the pressure vessel. The sample can easily be changed for another sample simply by changing the sample containing means containing the former sample for another sample containing means containing the latter sample, or the apparatus can easily be cleaned after the completion of observation of a sample for the observation of the next sample, simply by washing the sample containing means. Since the sample is contained in the small sample containing means instead of filling up the cavity of the pressure vessel and the associated piping, the apparatus requires only a small amount of sample for observation. Direct observation of the behavior of the sample under varying pressure visually, a microscope or a combina­tion of image pickup means and display means enables the accurate measurement of the crystallization pressure and pressure of fusion of the sample.

Abstract: Device for making two coaxial rotating mechanical elements (1, 2) integral by friction between two friction zones (3, 4) generated by traction on the inside element exerted by the threaded end with pitch n of shaft (10), screwing into a threaded hole (12) of inside element (1). 
     Shaft (10) is also laterally threaded with pitch (10') equal to that of threaded pins (7) supported by housing (9) coaxial with the shaft. 
     When end (11) of shaft (10) is screwed into hole (12), pins (7) rotate tangentially along the inside threading of pitch m of bushing (5) wedged in outside element (2) and translate with housing (9). 
     When friction surfaces (3, 4) of the two elements come in contact, a further rotation of shaft (10), pitches m and n being different, causes the relative locking. 
     Coupling between shaft (10) and pins (7) and the coupling between the pins and bushing (5) are of the forced type, obtained by an interference between the various threads.

Title: High volume low pressure air spray gun
Inventor: MELLETTE ROBERT R
IPC: B05D1/02
Filed: 1990-01-26
Abstract: A high volume low pressure air spray gun (20) has an atomizing air orifice (76) for atomizing a stream of liquid coating material into a conical spray and opposed side port air orifices (88) for flattening the spray into a fan-shaped pattern. The gun receives air at pressures up to about 100 psi, and an air flow restriction in the form of a venturi (110) is in an air supply passage in the gun barrel. A valve stem (54) for controlling the flow rate of air to the side port orifices (88) extends through the venturi (110), and is configured to vary the venturi air flow area in response to changes in the flow rate of air to the side port orifices. When the valve stem (54) is positioned for maximum air flow to the side port orifices (88), it establishes a maximum air flow area through the venturi (110) , such that a high pressure of air at the gun air inlet, after flowing through the venturi, results in a high volume low pressure air flow at the atomizing and side port orifices (88). When the valve stem (54) is positioned to reduce air flow to the side port orifices (88), it correspondingly reduces the flow area through the venturi (110) to maintain the pressure of air at the atomizing orifice below a selected maximum value. The gun may carry a paint cup (124), in which case the cup is pressurized by air downstream from the venturi to prevent overpressurization of the cup.

Abstract: In a novel method of manufacturing a relief printing plate by (1) imagewise exposure of a photosensitive recording element which comprises a dimensionally stable base (A) and a photopolymerisable, relief-forming recording layer (B) to actinic light, (2) washing-out (development) of the unexposed and, consequently, unphotopolymerised regions of the imagewise exposed relief-forming copying layer (B) with a developer solvent, and (3) post exposure (post treatment) of the photopolymerised relief layer obtained in this way to light of a wavelength  lambda  </= 300 nm, a photosensitive copying element is used whose photopolymerisable relief-forming copying layer (B) contains not only at least one photopolymerisation initiator but also at least one other photosensitive compound. Said other photosensitive compound is benzophenone and/or a monosubstituted or polysubstituted benzophenone which contains at least one photopolymerisable, olefinically unsaturated group in its substituent or in at least one of its substituents. If this novel photosensitive recording element is used in the novel manufacturing process, a relief printing plate whose relief layer has a nontacky printing surface is obtained even after a short postexposure (posttreatment).

Abstract: Aqueous polymeric microemulsions such as acryl­ic ester copolymers contain very fine particles having a number average particle size of generally 600 Angstroms or less. The glass transition temperature of the parti­cles is low and with respect to acrylic polymers is generally 20°C or lower. The aqueous polymeric micro­emulsion can can be based on polymers such as an acrylic polymer or copolymers thereof, vinylidene chloride poly­mers or copolymers, acrylonitrile-butadiene (nitrile) polymers or copolymers thereof, polyvinyl chloride poly­mers or copolymers, vinyl acetate polymers or copolymers, ethylene copolymers, and the like, as well as blends of the above. The polymeric microemulsions are made by uti­lizing at least one water soluble initiator or a redox initiator system and a low but effective amount of one or more emulsifying agents and adding the monomers thereto on an incremental basis. Acrylic polymeric microemul­sions are desired due to their high heat stability. The fine-size polymeric microemulsions have good film forma­tion, high pigment loading ability, unexpectedly high shear holding time, and the like. They are thus suitable for imparting improved strength to paper and when used with various fillers improve the opacity of the paper.

Abstract: A control system (method and apparatus) is adaptive on-line with changing process conditions, for example, the specific heat of a liquid used in a process. The system regulates a variable of a process (temperature of the liquid used in the process) and has a fast dynamic response to handle temperature transients while adapting to changing process conditions. The system uses feedforward and feedback control loops, which in the case of the process involving the temperature control of a liquid are respectively responsive to the temperature of the liquid before and after a control point. The system exercises adaptive control of the feedforward control function from the feedback loop. The system is preferably implemented with a digital computer. The fast dynamic response is enhanced by applying microwave energy from a microwave generator to heat the liquid at the control point with the feedforward and feedback control loops controlling the microwave generator.

Abstract: Circuitry and method for generating electrical currents representative of an exponential function of an input current. The circuit includes an input diode chain and an output diode chain. Each of the diodes in the input diode chain has an input current passing therethrough. The input current is produced by an input current source connected in sources with the diode below the cathode of the diode. A voltage driving circuit drives a voltage drop across the output diode chain that has a predetermined relationship to the voltage drop across the input diode chain. The voltage drop across the output diode chain results in a current through the output diode chain. The number of diodes in the output diode chain is preselected relative to the number of diodes in the input diode chain such that the current through the output diode chain is representative of an exponential function of the input current or currents.
