Abstract: A photogalvanic cell has a glass substrate through which irradiating light passes. A light transparent conductive thin film serves as an electrode, the film being deposited upon the glass substrate. Another layer is an electrolyte and includes an aqueous medium having TiO.sub.2 suspended therein, the TiO.sub.2 forming photoactive sites with the remaining ingredients of the electrolyte. The electrolyte layer further includes N-methylphenazine methosulfate dye which has photoconversion and electrical storage properties. During irradiation the cell may drive a load, or stored energy resulting from irradiation may drive a load after the source of irradiation is removed.

Abstract: A multilayer device has a coated photoelectrochemical electrode and a counterelectrode. The device is packaged without an electrolyte. However, when the device is immersed in sea water, the water acts as an electrolyte by contributing ions which makes photogalvanic action possible. The device may be fabricated in the form of flexible sheets which are easily transported and deployed for use in sea water. The device will generate electricity for a utilization device after it is immersed in sea water and exposed to light.

Abstract: A three-phase shift network includes a single transistor which controls phase shift by introducing a variable resistance into the network as determined by a D.C. control signal supplied to the transistor. The three-phase signals generated from the phase shift network undergo pulse shaping and are subsequently introduced into an opto-coupled pulse amplifier. The amplifier drives large SCR devices, connected as a load.

Abstract: A printing apparatus is provided for printing on a document, such as a bank passbook, which has affixed thereto a magnetic stripe on the cover on which information with respect to the print operation to be performed is written and/or read by a magnetic scanning assembly. The magnetic stripe is positioned on the document parallel to the centerfold and the unbound edge of the cover nearest the last line to be printed on the document. When inserted in the print apparatus, the platen of the printing apparatus clamps the document with stripe positioned above and aligned with the platen to facilitate the scanning of the magnetic stripe by the magnetic head of the scanner assembly. The magnetic head is spring loaded to accommodate surface variations of the magnetic stripe and different passbook thicknesses.

Abstract: The prolonged depression of a cursor scan control key on a CRT terminal keyboard generates a unique coded signal that is fed to a gating circuit. Prolonged depression is further detected by an astable circuit that generates repeated enabling pulses to the gating circuit so that the coded signal is repeatedly transferred to a separate programmable control unit. The unit is programmed to translate the repeated signals to a cursor scan command for a CRT which forms a part of the terminal.

Abstract: The cable from a travel trailer is disconnected from a mating connector of a towing vehicle. The trailer cable is then plugged into a flasher module to cause flashing of the trailer running, side and overhead lights. Energization of the flashing lights occurs from a battery in the trailer, totally independent from the battery of the towing vehicle.

Abstract: Apparatus and technique for use on a moving rail vehicle to detect, measure and record rail surface and side discontinuity by means of sensors mounted at intervals on the rail vehicle undercarriage. The sensors may be of the contact or non-contact variety, continually sensing track conditions. The sensor signals are transmitted to a peak detection system which evaluates the signals against prior values standarized for optimum track conditions. The system further determines peak values to indicate rail discontinuities. Analyzing, recording, and storing the signals are done with the aid of a computer processing unit and a magnetic tape unit as the storage medium.

Abstract: A method of filling a pressurized package, and apparatus therefor, is described in which a unitary valve body is aligned with a container neck, fluid under pressure is introduced through the neck and around the valve and then the valve is forced into the neck to seal the container, the valve having a body portion preformed to engage in a neck portion with interference, including rib and groove engagement, and the neck portion having a smallest diameter to depth ratio no greater than 5:1, and the valve body portion being long enough to extend through the neck to bulge into the container with the internal pressure of the container acting inside the valve to force the valve body portion radially against the neck portion.

Abstract: A roller assembly utilizes a ferrofluid as a lubricant (ferrolubricant). Integral structural portions of the assembly are made to have magnetic portions which create their own magnetic field gradient causing magnetic field maxima at points immediately surrounding the contact point between a particular roller element and its raceway. This in turn entrains the ferrolubricant around the contact point thus ensuring continued lubrication of contacting surfaces. Further, the entraining action prevents leakage of the ferrolubricant from the assembly.

Abstract: Sample air is divided into two paths. One path leads through a thermal converter where ambient NO.sub.2 is changed into NO. The other path passes through equivalent tubing to keep the air samples synchronized. Both samples then go to separate cells where each combines with ozone. The resulting chemical reaction produces light, chemiluminescence, which is measured by separate photo-multiplier tubes. Electronic circuits translate the results into simultaneous readings of NO.sub.x and NO concentrations. A difference amplifier subtracts the NO from the NO.sub.x to give a continuous NO.sub.2 value.

Abstract: A tubular rivet is picked up by a rivet engaging pin supported on a support which is releasably coupled to means for urging the pin into a position in which it can engage with a rivet. Control means allow the urging means to move the pin into the position at a first station. The rivet is moved to a second station at which a force bypassing the pin is applied to the support to break the coupling to cause the pin to move to an inoperative position to avoid permanent deformation of the pin. The control means causes the reconnection of the coupling as the pin is moved from the second station to the first station.

Abstract: Three log circuits are fed by respective x, y and z inputs, along with predetermined interconnections therebetween. The outputs from the log circuits are log z, log (x+z) and log (y+z). These outputs are fed to summing and anti-log circuits to derive the equation (xy)/z + x + y + z. A second summing circuit is provided for substracting the three variables from the resultant output so that (xy)/z is finally derived.

Abstract: A colorimeter includes an objective for focusing an object image on a first half of a viewing screen. A standard light reference beam is projected onto the second half of the screen. A moving shutter alternately blocks the first half then the second half of the screen. A light detector is responsive to the alternating images on the screen as they pass through color filters. The detector output may provide information of spectral distribution or color deviation of the object, relative to the standard reference.FIELD OF THE INVENTIONThe invention generally relates to colorimeters, and more particularly to a colorimeter for measuring color and spectrum distribution, based on the formation of an optical image of an object prior to measurement.BRIEF DESCRIPTION OF THE PRIOR ARTThe "narrow" definition of color flows from the rules set down by the C. I. E. (International Commission for Illumination) for the measurement of color on flat, uniform, opaque surfaces.

Abstract: A granular composition is comprised of primary carrier particles that are mixed with a liquid containing an active ingredient which saturates, by adsorption, the surface of each particle. A second carrier material is then mixed in so that secondary carrier particles adhere to the surface of each primary particle to form an agglomerate. The secondary carrier adsorbs additional liquid in the composition so that the composition may be handled as a granular mass.
