Abstract: Abstract of the disclosure An arrangement providing for a decision of high precision with relatively simple circuits. The input signal is delayed by a time D by means of a delay line. A first test signal of energetic character relative to the output signal of the delay line is produced. A circuit fed by the input signal produces a second test signal for identifying voiced sounds, this signal being prolonged by a time d.          An AND-gate supplies the speech decision signal, relative to the output signal of the delay line, in the presence both of the first test signal and of the prolonged second test signal. The times D and d allow for the possible presence of an unvoiced consonant preceding a voiced sound and of an unvoiced consonant following a voiced sound.

Abstract: ABSTRACT OF THE DISCLOSURE:         A photoconductive drum is formed with inner and outer photoconductive layers of different spectral sensitivi-ties.  First and second chargers apply electrostatic charges of opposite polarities to the drum to form a stratified charge pattern.  Radiation of a light image onto the drum causes electrostatic images to be formed in the layers according to color, the net surface potential being negative in areas cor-responding to one color such as red, positive in areas corres-ponding to another color such as black and zero in white background areas.  Firts and second developing units apply positively charged red toner and negatively charged black toner respectively to the drum to form a two color toner image.  Where only one charger and only one developing unit is actuated for operation, a positive or negative copy in either color may be produced.  The copying machine is operative in either of five copying modes merely by selectively actuating the chargers and developing units in correspondingly different combinations.

Abstract: Abstract of the Disclosure The total weight of fibrous material delivered to a packaging device, such as staple textile fiber delivered to a baling press, is controlled so as to facilitate achieving more uniform package weight in accordance with a method and through the use of an apparatus in which material is successively accumulated into batches, each of which is a fractional portion of a desired package weight.  Batches are accumulated and released as the actual weight of each delivered batch is determined and registered and the regis-tered actual weights of the successive batches are totaled.  The weight of at least certain batches in the succession is then adjusted in such a manner as to closely control the total weight.  A weigh container having an inlet and an outlet is interposed between and opera-tively communicates with a source of supply of fibrous material, such as a tow cutter, and a packaging device, such as a baling press.  A load cell is provided which signals the weight of material supported by the weigh container.

Abstract: ABSTRACT OF THE DISCLOSURE A silicone fluid is provided herein which is curable to a hydraulic elastomer having a viscosity of 1000 to 1,000,000 centipoises at 25°C.  The silicone fluid comprises a copolymer of dimethylsiloxane units with 0.1 to 0.9 percent of methylvinylsiloxane units; the mole percent of methylvinylsiloxane units having a value of (4.8/log V) - C, where V is the viscosity in centipoises and C is a number having a value of from 0.53 to 0.83; the copolymer having end groups selected from the class consisting of trimethylsiloxy, hydroxy and alkoxy with a vinyl-specific peroxide to provide the hydraulic elastomer.  Such hydraulic elastomer is characterized by a combination of a high cross-link density and a  high proportion of free chain ends.  It crumbles to a powder under high shear stress, but has the unique property of flowing like a viscous, fluid through a narrow ofifice.  It is useful in hydraulic impact absorbers and other hydraulic systems.

The already defibered fibers are directly infed for further processing.  The removal of the contaminants can be accomplished at a suspension density in the order of 1%, whereas the defibering or pulping of the waste paper in the stock pulper occurs at about 4%.  The employed sorting appa-ratus is connected with the stock pulper, while dispensing with the use of a sieve or screen.

Abstract: BIOHAZARD CONTAINMENT APPARATUS AND METHOD             ABSTRACT OF THE DISCLOSURE      The containment of biohazardous substances, which may exist in the streams of sample material that are being separated in air into droplets in a testing chamber of equipment, such as cell sorters and cytofluorometers, is attained by subjecting the testing chamber to negative air pressure, so that inward air flow at the open face of the chamber is sufficient to inhibit biohazardus substances from exiting out from the face of the chamber.  A region of air stagnation is created around the sample streams so that the streams are not deflected from their paths, such paths being pertinent to their testing of the biological sample material.  The air stagnation region is formed by interposing an air diverter between the sample streams and the air flow exhaust port at the rear of the testing chamber.

Abstract: ABSTRACT OF THE DISCLOSURE This heating blow-molding machine fabricates a number of bottle-shaped containers of biaxially oriented plastic piece or parison by supplying the plastic pieces to a heating unit to heat them to the orientation temperature and then supplying them to 12-station rotary blow molding machine for biaxial orientation.  Each of the plastic pieces or parisons is made of polyethylene terephthalate resin to provide a thin-walled transparent bottle-shaped container of cylindrical shape with one bottom and a prefinished neck portion injection molded simultaneously in numerous number by an injection molding machine.            This blow-molding machine consists of a turntable for the heating unit, a turntable for a blow-molding machine, and a turntable for loading and unloading the pieces and the products blow-molded from the pieces.  Each of the turntables is continuously turned in predetermined direction at an intrinsic speed set with respect to the number of stations provided thereat, the time required for heating the pieces, and another time required for blow-molding and cooling the pieces, etc.  Further, a rotor is employed to transfer the pieces or container  products between the  turntables rotated at their intrinsic speeds, respectively.  The rotor is rotated according to a speed curve at a moving speed equal to the peripheral speed of the turntable opposite to the turntable for transferring the pieces held thereby at the holding portions.  This invention thus provides a heating blow molding machine which can increase largely the number of products blow-molded per unit time, and smoothly rotates the essential rotating portions thereof to thereby eliminate mechanical trouble.
