Abstract: ABSTRACT OF THE DISCLOSURE         A method for preparing dried flaked textured high vege-table protein which instantly hydrates and has an improved flavor. The process includes texturizing vegetable protein material by subjecting such vegetable protein material containing moisture to a pressure of at least 1,800 pounds per square inch for a time and at a temperature sufficient to convert said moisture into steam whereby such vegetable protein material is partially disem-bittered, toasted without scorching and is compacted into a hard and  substantially fused mass having textured characteristics.  The fused mass is fragmented into particles.  The textured vegetable protein material is sized so that the retained portion of the tex-tured vegetable protein material has a particle size between one inch and 0.04 inch.  The retained portion or fraction of the sized textured vegetable protein material is hydrated by adding enough water to raise the mixture content of the textured vegetable protein material to between 12 and 25 per cent.  The hydration is achieved at n temperature of 0° to 250°F. under a pressure from atmospheric to 15 psi preferably for a period of 3 to 24 hours. The hydrated textured vegetable protein material is flaked in flaking rolls.  The flaking rolls are adjusted to produce flakes having a thickness of 0.06 to 0.001 inch and a bulk density of 9 to 37 pounds per cubic foot. The flaking rolls have a roll surface temperature which is either cold, ambient or hot. The flaked textured vegetable protein material is dried by reducing the moisture content of the flaked textured vegetable protein material to 10 or to as low as 2 per cant. The drying is done by heating the flaked textured vegetable protein at a temperature of 90° to 500°F. for 20 seconds to 24 hours. The dried flaked tex-tured vegetable protein material has a bulk density of 7 to 30 pounds per cubic foot. The dried flakes can be used in various food compositions.

Abstract: Abstract of the Disclosure A low level, low power, direct coupled integrated class B amplifier having a dual channel three stage preamplifier and a pair of output transistors, one for each channel.  In each channel, a DC negative feedback loop connects the collector of the last stage preamplifier transistor to the base of the first stage preamplifier transistor to regulate the DC levels, and a resistive AC negative feedback loop connects the output transistor collector to the first preamplifier transisitor collector to reduce the gain dependence of the channel on the current through the output transistor, thus enabling very low idle currents for the output transistors and also providing low distortion output.          The resistor in each AC feedback loop is a floating tub resistor to enable it to be taken more than .6 volts above the battery voltage.  Common mode rejection is provided for at least two of the three preamplifier transistors of each channel.

Abstract: ABSTRACT OF THE DISCLOSURE      This method is particularly suited for practice on a multiple spindle screw machine in which each work spindle carries a length of bar stock.  The work end of each bar is formed, mixed and drilled in a conventional manner to form thereon a wheel shaped workpiece which is then rotated between two thread dies to form diagonal grooves in its periphery.           The work is then subjected to two successive breaching operations which out grooves transversely of the lands formed by the threading dies.  When the work has entered the bore of the second breaching tool, the tool is related slightly relative to the work to upset the teeth so that their sharp cutting edges are caused to face outwardly.
