Abstract: ABSTRACT OF THE DISCLOSURE An anti-hemocytic serum for suppressing the immunolo-gic mechanism of insects which is inactivated blood plasma of immunized animals produced by the immunization of animals with a hemocyte suspension separated from cells of the bodies of insects: the titre of hemocytoagglutinins of the anti-hemocytic serum being 1:256 to 1:2048.  A method for the preparation of the anti-hemocytic serum comprises in removing the alimentary tract and the hemolymph from insects, preserving the remaining cells of the bodies of insects and homogenizing them to form a hemocyte suspension  subjecting the suspension to centrifugation, washing off the preservative from the suspension before immunization and immunizing animals 4 times at intervals of 5 days by injecting a 50% hemocyte suspension in an amount of 0.07 ml per 100 g of the weight of the animal, isolating the blood plasma of animals after immunization and inactivating the plasma.

Abstract: Abstract of the Disclosure For the purpose of forming hydrogen or hydrogen peroxide from water vapor, or accomplishing other photochemical reactions, a reaction chamber is provided with mercury vapor quartz discharge lamps.  In close proximity to the lamps are spheres, or thin continuous wires, or filaments or other physical configurations of laser-type material which produce relatively coherent radi-ation in a manner similar to lasers.  The spheres or filaments include con-centric partially reflective surfaces, and include an active material which is pumped by the efficient spectral radiation of the mercury vapor, and radi-ates at a frequency or frequencies matched to the absorption characteristics of the feedstock being fed through the reaction chamber.  The laser-type material may be operated to produce output radiation at a harmonic, such as the second, third, fourth or higher harmonic of the basic laser radiation, and these harmonic output radiations may be enhanced by using semi-reflective coatings which reflect in the order of 70% to 90% of the radiation, particu-larly in the case of spheres.  High energy consent ultraviolet radiation may also be generated by the "beating" of radiant energy from the mercury vapor tubes and the laser-type material.  Efficiency is enhanced by chain reactions which occur with the feedstock materials being fed to the reaction chamber; When water vapor and air containing oxygen are fed into the reaction chamber and are irradiated at the appropriate frequency including high ultra violet frequencies, chain reactions occur which involve the generation of activated oxygen atoms.  These activated oxygen atoms react with additional water vapor molecules to form hydrogen gas and/or hydrogen peroxide, with an additional activated oxygen atom being available for further reaction.  Other compounds, including various organic and chlorine containing compounds may also be efficiently reacted using the present techniques.

Abstract: ABSTRACT           A foot pump comprises a base member and an operating member pivotally connected to the base member. A piston-and-cylinder assembly is connected between the members.  In use the user depresses the operating member with his or her foot, thereby causing air to be compressed in and expelled from said assembly,  A return spring in-corporated in said assembly returns the operating member to its raised position.  The assembly can be disconnected from the base member and connected to the base member again, at will, and the whole is so arranged that when the assembly is disconnected from the base member the pump can assume a storage position in which the operating member is in a depressed position and the return spring is not loaded, or at least not significantly loaded.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides a process and apparatus for manufacturing flat plastic net. Tubular plastic net is made by extruding plastic material through coaxial cir-cular counter-rotating die members to form a net structure having a plurality of crossing strands. The anglar dis-placement of successive longitudinally-aligned junctions of the crossing strands is controlled, preferably by con-trolling the relative counter-rotation of the extrusion die members, and successive longitudinally aligned junc-tions are cut longitudinally within each junction. The tubular net so cut is opened out to form flat net. The flat net so produced, the edges of which are charaterized by successive longitudinal edge junctions, in which each edge junction is cut long-itudinally within the junction, is particularly useful for fencing material, for example.

Abstract: ABSTRACT           Closed   loop  timing  and   fuel  distribution controls for an, internal combustion engine operative to control the timing and fuel delivery to each engine com-bustion chamber  is disclosed herein.   The closed loop timing and fuel distribution controls are closed about the instantaneous rotational velocity of the engine's output shaft and generate  timing  and  fuel  correction signals operative to modify the timing functions of the engine as well as the quantity of  fuel delivered to each of the engines combustion chambers.  The control generates from the crankshaft's instantaneous rotational velocity a pro-file of each torque impulse imparted to the engine's out-put shaft and computes the phase angle signal indicative of the phase angle of each torque impulse to generate a timing correction signal indicative of the difference be-tween the computed phase angle signal and a desired phase The control further distribution computes the torque of each torque impulse and generates a torque correction sig-nal  indicative of  the difference between the generated torque and average torque values.  The two correction sig-nals applied to an engine control modify the timing and fuel control signals being generated to cause the phase angle of the generated torque impulses to occur at the desired phase angle and the fuel delivery to each combus-tion chamber to be increased or decreased by an amount corresponding  to  the  value  of  the  torque  correction signals.    The  torque  corrected  fuel  delivery  signals equalize  the  torque  contribution  of  each  combustion chamber to the total output torque of the engine.
