Abstract: THERMOPLASTIC BALL CORE         ABSTRACT       A method of forming a ball core is disclosed.  A flowable homogeneous mass of a thermoplastic resin and a blow-ing agent is injected into the spherical cavity of a mold under temperature and pressure conditions sufficient to activate the blowing agent.  The mold is cooled to 32°F to 65°F so as to form askin on the surface of the mass.  The mass is held within the mold cavity for a sufficient time so that the skin has adequate strength to prevent its rupture by lowing agent contained within the mass, upon removal of the mass from the mold cavity.  The mass is sealed at an exterior temperature of 32° to 65°F.  A ball core for baseballs and softballs is also disclosed.

Abstract: COLOR SIGNAL REPRODUCING SYSTEM AND CIRCUIT FOR THE SAME  ABSTRACT OF THE DISCLOSURE           In a television color signal reproducing circuit, a red color difference signal from a color demodulator is corrected by a blue color difference signal, and the blue color difference signal is corrected by a luminance signal.  The phase of a color subcarrier signal to be supplied to the color demodulator is controlled by the corrected red color difference signal during reception of a VIR signal, and the level of a color signal to be supplied to the color demodulator is controlled by the corrected blue color difference signal.  The controls of hue and color saturation are facilitated by the use of the corrected color difference signals.  It is also possible to deliver from the color demodulator color difference signals which match the fluorescence characteristics of a color picture tube.

Title: Picture signal receiver for facsimile and the like
Inventor: MINAMIBAYASHI SEISAKU
IPC: G06K15/10
Filed: 1979-05-08
Granted: 1982-08-17
Abstract: Abstract of the Disclosure The invention involves the simplification of a receiver/reproducer for facsimiles of the type which applies a constant amplitude signal of variable duration to a thermal sensitive paper.  Use is made of two analog memories for storing alternately successive one-line segments of the picture signal.  During the write-in period for a one-line segment, the immediately preceding one-line segment is subjected to amplitude comparison for each pic-ture element, in which the comparison reference voltage is changed correspond-ing to the shade value vs. time duration characteristics of the recording paper.  Thus, the amplitude comparison translates the amplitude information of the memory readout into the width of the comparison output pulse for each picture element defined by the  pitch  of the analog memories.  With the com-parison reference voltage supplied in common to all the amplitude comparators equal in number to the number of picture elements in one scanning line, the parallel output pulses from the parallel amplitude comparators have various pulse widths representative respectively of the amplitudes of respective picture elements.  Thus, the reproduction of a picture having a gradation of shade values is realized.

Abstract: APPARATUS FOR STACKING LAYERS OF OBJECTS               ABSTRACT OF THE DISCLOSURE      Objects to be stacked on a pallet or packaged without using a pallet, are transported by a conveyor to an inlet roll track where the objects are assembled into rows, from the inlet roll track a row of the objects is transferred to an intermediate support member where a layer of rows of the objects are collected and then picked up by a forklift device for movement to a pallet or a stack support.  The inlet roll track is made up of a number of rollers which can be driven at variable speeds with the rollers most remote from the inlet to the inlet roll track moving at the lowest speed.  Alternatively, the rollers of the inlet roll track can be arranged in groups with each group operating at a different speed and capable of being switched on and off separate from the other groups.  The stack support can be moved vertically so that the forklift device places each layer on it in about the same horizontal plane as the stack is built up.

Abstract: ABSTRACT OF THE DISCLOSURE               Polyphosphazene copolymers are prepared which contain randomly distributed units represented by the formulas               and      wherein X is a -OX(OR)m-1 radical in which Z is B+++, P+++, Si++++ or Ti++++, m is the valence of Z, R is a branched, straight chain or cyclic alkyl group containing from 1 to 12 carbon atoms or mixtures thereof and wherein X1 is selected from the group consisting of substituted and unsubstituted alkoxy, aryloxy, amino and mercapto groups.  The alkyl groups may vary in carbon chain length or structure within the radical as they may all be the same.         In the copolymer units represented by the above formulas, all X substitutent groups may be the same or they may be mixed and all X' substituent groups may be the same or mixed.  In the mixtures, the X substituent groups may be mixtures of different -OX(OR)m-1 groups and the X' substituent groups may be mixtures of different alkoxy, aruloxy, amino and mercaptan groups.         The specific proportion of X to X' substituent groups incorporated in the copolymers of the invention may vary considerably depending upon the particular end use for which the copolymer is intended, chemical and physical properties desired, and the degree of crosslinking desired.  In general, the copolymers may contain from about 0.1 to about 55 mole percent of the X substituent and from about 45 to about 99.9 mole percent of the X' substituent.  The preferred range is from about 0.5 to about 20 mole percent of the X substituent and from about 80 to 99.5 mole percent of the X' substituent. For applications such as moldings, coatings, foams and the like, the copolymer should contain at least ten (10) percent by weight of the X substituent.         The copolymers of the invention can be utilized to form protective films and may also be utilized in applications such as for moldings, coatings, and the like.  The copolymers of the invention also crosslink at room temperature in the presence of water yielding a solvent resistant film.

Abstract: Abstract Metal such as aluminum is produced electrolytically from metal chlorides or other halides dissolved in a molten solvent bath of higher decomposition potential in a cell includ-ing one or more carbonaceous or graphite cathode surfaces spaced from opposed anodes, particularly a bipolar cell, with bath flow through the spaces between the anodes and cathodes.  The wetting characteristics of the graphite cathode with respect to the metal deposited there by electrolysis are selectively balanced with the bath flow over the cathode and with the anode-to-cathode distance.  Cathode surface wear rate is substantially reduced if the surface is wettable by the metal in regions of low bath flow velocity or regions of greater anode-cathode distance.  The wear rate is also reduced by using a non-wettable cathode surface in regions of higher bath flow velocity or regions of closer anode-cathode distance.

Abstract: ABSTRACT           In the process for electrowinning of zinc from acid zinc sulfate electrolyte, electrolyte is recirculated to the cells and a portion of the electrolyte is returned to the leaching operation of zinc-bearing material.  by only returning electrolyte that overflows from electrolytic cells that contain new and/or recently cleaned anodes to the leaching operation, the amount of sludge in the cells can be reduced, the period between cleanings of cells can be lengthened and the amount of addition agent for controlling the lead content of deposited zinc can be reduced.  Electrolyte overflowing from only those cells that contain new and or recently cleaned anodes is diverted and kept separate from recirculating electrolyte from all other cells by providing separate means for collecting and transferring electrolyte to the leaching operation.  Such means may consist of two separate overflow pipes in the cell overflow means, and shut-off means, whereby electrolyte can be directed either into the recirculation circuit or to the leaching operation, or both, as required.
