Abstract: ABSTRACT          A novel combination and a method are disclosed for detecting and measuring a predetermined substance capable of being specifically bound, for example, an antigen, an antibody, a hapten, or a low molecular weight substance, in a sample.  The substance capable of being specifically bound is generally an immunochemical substance.  The combination comprises a novel adapter which eliminates contact with the sample, while providing reproducibility of test results, so that many samples can be tested manually and economically in a relatively short period of time.  The novel combination comprises (1) a fiber optic color-imeter comprising a light source, a means for detecting and measuring light, and a probe containing a plurality of optic fibers including a first light conducting means for conducting light from the light source of the colorimeter to a test sample and a second light conducting means for conducting light from the test sample to the means for detecting and measuring light of the colorimeter, and (2) a microplate having one or more wells, each of which is adapted to contain a liquid test sample, for use in a predetermined colorimetric medical diagnostic test, wherein a reflective surface is disposed below the bottom of the well of said microplate, and said well is adapted to accommodate the probe of said fiber optic colorimeter, and wherein said probe includes an attachments means joinable in a close-fitting engage-ment with an upper portion of each well in said microplate with-out engaging said liquid sample.  The detection and measurement of an immunochemical substance using the method and apparatus of the invention involves providing for the agglutination of a sus-pension of particles in a sample, or color intensity of solutions, by which, using the combination of the invention to determine certain electromagnetic radiation properties of the sample, the presence and amount of the immunochemical substance can be determined.  The method of the invention is especially suitable for rapid manual examination of samples in wells of microplates that are commercially available.

Abstract: ABSTRACT OF THE DISCLOSURE         A de-inking process for removing ink and other substances from printed paper which process is capable of providing de-inked paper stock hav-ing improved brightness.  The process utilizes an aqueous de-inking solution containing a mixture of certain surfactants, at least one surfactant being a water-soluble nonionic surfactant and the other surfactant being an oil-soluble nonionic surfactant.  De-inking is carried out at a temperature in the range of about room temperature to about the boiling temperature of the solution by forming a slurry of the printed paper in the solution having a predetermined fibrous material solids content.  The total nonionic surfac-tant concentration in the de-inking solution can be about 0.1 to about 5 weight percent, preferably about 0.5 to about 2.5 weight percent, based on the amount of fibrous material solids present.  The weight ratio of the water-soluble surfactant to the oil-soluble surfactant in the mixture is in a range of about 6:1 to about 3:1, preferably about 4:1.

Abstract: ABSTRACT OF THE DISCLOSURE       An infrared intrusion detector has an optical system for gathering infrared radiation from discrete sensitive regions and focusing such received radiation onto an infrared radiation sensor. The detector includes a monitoring device to sound an alarm when radiation sensed reaches a predetermined level.  The optical system comprises an optical collector for gathering radiation from a field which includes the sensitive regions and for converging such radiation onto a plurality of reflectors.  Each reflector determines one of the discrete sensitive regions and, in turn, is oriented to reflect converging radiation gathered from a sensitive region on the detector.  The invention provides a simple, efficient optic system for a broad field of gathering infrared radiation, concentrating and focusing it in a manner to provide sufficient levels of received radiation for purposes of detection.

Abstract: IMPROVEMENTS IN SOLENOID DASHPOT               PEDAL ACTUATOR ASSEMBLIES     ABSTRACT OF THE DISCLOSURE     There is disclosed a solenoid-dashpot assembly for actuating the foot pedals of a player piano. A solenoid having an armature shaft extending beyond the coil area of the solenoid receives a piston element, which, in turn, has an O-ring which co-acts with a dashpot cylinder.  Constricted air passage elements are formed in the piston element and are provided with relatively large air passages which have mufflers thereon so that no sound is made when air ingresses or egresses through these constricted passages due to actuation and deactuation of the solenoid.  To silence both end part of travel of the solenoid armature, the solenoid is mounted above a base plate on a mounting bracket and the solenoid armature carries a pad extending from a side opposite the dashpot.          The base plate has an adjustable pad thereon opposite the pad on the solenoid armature so that on actuation and deactuation of the solenoid, there are no noise generating, hard surface to hard surface contacts at either end point of solenoid armature movement. These elements are provided so as to enable the solenoid dashpot assembly to more closely approximate the action of the piano player in the depressing the pedals of the piano, and at the same time,  be almost completely silent.

Abstract: INVENTOR:  IGNAZIO MARCHIORO        INVENTION: CONTROLLED DEFLECTION ROLL                             ABSTRACT OF THE DISCLOSURE       A controlled deflection roll having a roll shell rotatably mounted at its ends at a stationary roll support.        Pressure or support elements are located between the roll shell and the roll support.  The bearing or mounting arrangement of the roll shell at the roll support is provided with play, in a direction opposite to the direction of application of the force exerted by the pressure elements.  In such play there is effective a force opposing the direction of the force of the pressure elements.  If this force is exceeded by the force of the pressure elements, then a control device limits the force exerted by the pressure elements to a value which is not dangerous for the roll shell.  According to a preferred con-struction the control device is constituted by a hydraulic shutoff element which, in the case of a hydraulic controlled deflection roll, opens an outflow channel leading from the pressure line or conduit, and thus, lowers the pressure effective in the pressure line.

Abstract: ABSTRACT OF THE DISCLOSURE A facsimile transmitter detects dark-light variations in an illuminated document by means of a photodetector. Fiber optics form an optical pathe from the illuminating means to the document and from the document to the photodetector means with filter means being located in the optical path for attenuating light in the near infrared region of the spectrum. Amplifier means are coupled to the photodetector means and automatic gain control means are associated with the amplifier means for increasing the gain of the amplifier in response to a lesser amount of light detected by the photodetector. The gain control means is adjustable so as to limit the increase in gain when detecting dark regions. Lead networks are coupled to the amplifier means to increase the speed of response to dark-light variations in the document.
