Abstract: A capacitive pressure transducer system includes a reference capacitor and a capacitor which varies with pressure; and circuitry which involves alternately charging one of the capacitors to a reference voltage level, and then switching to charge the other capacitor; and circuitry for producing an output voltage which varies as the duty cycles of the two capacitors shift; and the output is therefore substantially proportional to the pressure changes. Feedback is provided to incrementally change the capacitor charging and switching timing or duty cycles by changing the charging current or the reference voltage at which switching occurs, to substantially eliminate deviations from linearity in the voltage versus pressure characteristic.

Abstract: The corrosive alkaline surface layer of an epoxy resin product formed by the curing of the epoxy with an aliphatic amine is eliminated by first applying a non-solvent to remove most or all of the free unreacted amine and then applying a layer of a chemical reagent to neutralize the unused amine or amine functional groups by forming a substituted urea. The surface then may be rinsed with acetone and then with alcohol. The non-solvent may be an alcohol. The neutralizing chemical reagent is a mono-isocyanate or a mono-isothiocyanate. Preferred is an aromatic mono-isocyanate such as phenyl isocyanate, nitrophenyl isocyanate and naplthyl isocyanate.

Abstract: Cotton-containing toweling is dyed in a dye bath solution containing a coloring amount of at least one phosphonic acid fiber reactive dye together with sufficient acids such that the fiber reactive dye reacts with and attaches to the cotton of the toweling. The deybath-saturated toweling is passed through a high expression roll until the wet pickup is in the range of about 40-55 percent wpu, and then the toweling is heated to a temperature of at least 200 degrees F. for a time sufficient to fix the dye onto the cotton producing a fully penetrated, evenly dyed toweling. The toweling may be printed in a predetermined pattern with a print paste after passage through a high expression roll and before final heating.

Abstract: Movement of an object (intruder) in a specified area is sensed by transmitting microwave energy from an antenna (10) that also receives energy reflected from the intruder, where the received energy is quadrature processed using Doppler techniques. Connected to the antenna (10) is a transceiver (12) that includes a quadrature mixer (48) coupled to an RF oscillator (50) through an RF switch (52). The RF switch (52) is controlled by a switch driver (54) to provide pulse energy from the antenna (10). Doppler outputs E.sub.1 and E.sub.2 from transceiver (12) are processed in the same manner except for a 90-degree phase lead applied to the Doppler output E.sub.2 by a phase lead network (18). Doppler outputs E.sub.1 and E.sub.2 (E.sub.2 90-degree phase shifted) are applied simultaneously to a sum and signature processor (24) and to a difference and signature processor (22). The sum and signature processor provides the "approach" receiving signal and processes the signature to further reduce the nuisance alarm rates.

Abstract: This invention pertains to allergen-containing substances, methods of preparing the same and using the same as immunologically specific suppressants of the production of reaginic antibodies directed to the allergen in question. The allergen-containing substances can be characterized as covalent conjugates of the allergen molecules with non-immunogenic water-soluble polymers. The degree of conjugation is such that the conjugates are rendered tolerogenic as well as substantially non-allergenic and non-immunogenic. The new conjugates are useful for immunologically specific suppression of common allergies in mammals, including humans, which are mediated by reaginic antibodies of the IgE class.

Abstract: In a spectrophotometric measuring apparatus sample liquid is pumped into a substantially cylindrical cuvette having an internal dimension such that a meniscus of a leading edge of a liquid sample pumped therethrough is maintained. Radiant energy directed through the sample liquid is directed across the path of fluid flow rather than along the length thereof. Consequently, spectrophotometric measurement is performed using a significantly reduced optical pathlength.

Abstract: Apparatus for treating bean sprouts to remove hulls, cut-off roots from the sprouts, and to wash them. The apparatus comprises essentially an open-top tank having a chute at one end for receiving sprouts to be cleaned, and a plurality of jets adjacent to the chute which delivers water thereto to agitate the sprouts. A source of water under pressure includes spray nozzles for filling the tank and further agitation. A conduit extends to a low pressure screen drum. From the latter, another conduit extends to a pump. A discharge chute communicates with the screen drum. Between the screen drum and the feed chute is a cylindrical screen which rotates in unison with the screen drum. A motor-driven drive belt rotates the screen drum and the cylindrical screen in unison. The cylindrical screen enhances the agitation and partially removes foreign material from the cylindrical member. The screen drum also has a plurality of radially extending blades which not only further the agitation, but also pick up foreign matter.
