Abstract: The present invention is a proteinaceous food product and a method of its production. A mixture of protein and water is formed into a thin film between successive parallel rolls rotating in opposite directions and at sequentially increasing speeds so as to impart at least a 40% stretch to the film prior to removing the stretched film from the last roll with a blade set at an angle to the roll. The scraping off of the thin film forms a structure consisting of groups of many small folds interspersed on substantially larger folds. Compaction of this material creates a fiberous structure composed of the numerous small folds of material surrounded by a matrix of the material once comprising the larger folds. This compacted structure approximates the structure of natural meat where fibers are dispersed in a matrix of connective tissue.

Abstract: A method for control monitoring the phase, depth, and area polarization of a piezoelectric transducer element. A piezoelectric element is energized by electrical pulses of controlled amplitude, duration, and repetition rate, and the response of the element is recorded by an oscilloscope or other suitable device. By properly matching the configuration, duration, and repetition rate of the driving pulses, with respect to the desired depth and phase of individual element layers, controlled-phase controlled-volume transducers may be achieved with a single piezoelectric transducer element.

Abstract: An improved integrating nephelometer having superior sensitivity and long-term stability to previous designs includes a container defining a measurement chamber. A continuously energized light source, such as a tungsten filament incandescent bulb, illuminates the measurement chamber through an opal glass diffuser. The intensity of the light source is regulated in one embodiment by a simple optical-electric feedback system, and in another embodiment by a voltage regulated supply. A cone of observation of the chamber is defined by a plurality of spaced, apertured plates located in the chamber, at right angles to the light source. A measuring photomultiplier tube views the cone of observation and provides an output signal including components resulting from detected photoelectrons, noise, and thermally emitted "dark current" electrons. A photon-detecting apparatus removes the noise component and provides an output pulse for each photoelectron and "dark current" electron.

Abstract: The pH of milk is lowered to 4.5 to 5.5 by direct acidification without the necessity of cooling the milk to avoid local coagulation and casein precipitation by adding acid as a spray from above a portion of the milk surface undergoing high velocity mixing.

Abstract: A method for obtaining controlled depth, controlled area, and controlled phase polarization of a piezoelectric transducer element. A controlled phase bias voltage is applied to two generally opposing surfaces of the transducer element, and heat is then applied in a pulsed fashion to one of the two surfaces. By properly coordinating the phase of the bias voltage and the pulsed heating of the one surface, discrete layers of polarization may be created between the two surfaces, the phase, area and depth of the discrete layers being accurately controllable.

Abstract: An optical fiber deflection device is described in which an electrical transducer is used for deflecting the fiber in response to an electrical control signal in order to deflect a light beam transmitted through such fiber. The transducer includes a nonmagnetic deflector means attached to the fiber and connected to an electrical current source, for deflection of the fiber by movement of the deflector means. In one embodiment employing an electromagnetic transducer, an electrical conductor is attached along the length of the fiber and is connected to a D.C. current source to produce a magnetic field around the conductor so that they may be deflected by pairs of electromagnetic coils positioned adjacent the side of the conductor when a control signal is applied to such coils. Alternatively, the control signal can be applied to the conductor attached to the optical fiber and a D.C. current caused to flow through the electromagnetic coils.

Abstract: Improvements in apparatus for converting one form of energy into another form with the use of an essentially closed, continuous loop passageway containing a plurality of freely movable, unrestrained bodies. Force generated by expansion of a gas is applied to successive bodies in one region of the passageway to propel them around the passageway in one direction. At another point in the passageway, at least a portion of the kinetic energy of the propelled bodies is converted into another form of energy. Each body, before being propelled around the passageway, enters a compressor section where it compresses the gas in the passageway, the compressed gas being bled off through a check valve where energy is added to it before it is used to propel a body around the passageway in the expander section which immediately follows the thrustor section.
