Abstract: RCA 72,161 PINCUSHION CORRECTION CIRCUIT  Abstract Of The Disclosure A side pincushion correction circuit is coupled to a horizontal resonant retrace circuit which includes a retrace capacitor and a horizontal deflection winding.  The correction circuit includes an inductance and a controllable switch which is turned on during each horizontal retrace interval.  A compensating circuit comprising secondary winding of a flyback transformer is coupled to the inductance and reflects the inductance onto the primary winding side in series with the deflection winding when the switch is open circuited and reflects the inductance in parallel with the deflection winding when the switch is conducting.  The on-off ratio of the switch during horizontal retrace is modulated at a vertical parabolic rate to achieve side pincushion correction.  The turns ratio of the flyback transformer is selected to adjust the resonant frequency and the retrace time modulation created by the correction circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           Certain thermoplastic polymer blends have tensile strengths greater than that of any one polymer component.  The blends comprise (1) at least one ethylene-propylene-diene (EPDM) polymer, (2) at least one ethylene-ethyl acrylate (EEA) polymer, and (3) optionally, at least one polyethylene.  The blends are prepared by mixing physically the polymer components under heat and shear conditions.  No curing or cross-linking agents are needed to obtain the superior tensile strengths of the thermoplastic blends.  The blends are useful to prepare tubing, sheet products, wire and cable insulation, molded items and the like.

Abstract: Title of Invention:  RODENTICIDES COMPRISING 6-AMINONICOTINAMIDE       AND 6-AMINONICOTINOHYDROXAMIC ACID.                       Abstract Anticoagulant compounds have been extensively used as rodenticides during the last 20 years.  In most parts of the world rats have become resistant to anticoagulants.  This circumstance seriously limits the usefulness of anticoagulant rodenticides, and gives rise to the need for a novel effective rodenticide.  6-Aminonicotinamide and 6-aminonicotinohydroxamic acid have been found to be potent rodent poisons, moreso in the rat than in the mouse.  They are much less toxic to other species, such as the dog.  An important feature of these compounds as rodenticides is the fact that nicotinamide is an excellent and complete antidote, even when administered after toxic symptoms have appeared.  6-Aminonicotinamide and 6-aminonicotinohydroxamic acid do not have objectionable taste or odor, and hence can be mixed with food products as edible carriers.  These compounds are single-dose rodenticides in that the ingestion of only a few milligrams is fatal to a rodent, resulting in death which occurs a few days after ingestion of the poison.  Unlike the anticoagul-ant poisons, the mechanism of action of 6-aminonicotinamide and 6-aminonicotinohydroxamic acid is such that the development of resistance to the is virtually impossible.

Abstract: An encipher-decipher device Abstract of the disclosure An encipher-decipher apparatus including an input keyboard and a processing and control stage which enciphers or deciphers data re-ceived directly from the keyboard or preferably from a text store with the aid of a cipher generator. The cipher generator produces a cipher sequence dependent on two code data items that determine the initial state of the cipher generator. One item for encryption is supplied as a set of random code characters from a random generator. The random generator comprises a continually cycled modulo-n counter and a FIFO memory into which the instantaneous state of the counter is entered at each of successive actuations of keys of the keyboard, such key opera-tions being those done in any event in the use of the apparatus. The cycle time of the counter is much less than the time between consecu-tive key operations. A clock rate of 100 kHz is suggested. The set of characters is read out of the FIFO store at the start of data process-ing for use by the cipher generator.

Abstract: ABSTRACT           A method for quantitative propagation of hemotropic parasites, especially Babesia parasitefi, in vitro.  Babesia-infected erythrocyte cultures are incubated in an environment of enhanced carbon dioxide tension wherein the culture medium overlay provides a barrier to oxygen transmission such that cellular hemoglobin is essentially maintained in its deoxy state.  By varying environmental carbon dioxide tension, merozoite stages of the parasite are selectively reversibly induced to migration between residence in host cells or culture medium, rendering possible the isolation of infective antigenic merozoites in large quantities.  Specific Babesia antigen is harvested in large quantity from the in vitro culture medium.
