Abstract: ABSTRACT                Disclosed is an arrangement for a VLSI circuit, comprising an improved input register useful at least for generat-ing sequentially pseudo-random input operands, wherein the in-put register is a serial shift register comprised on a chain of serially shifted flip-flops from first to last having a serially shifted external input to its first flip-flop.  When configured to generate such operands, the register comprises a plurality of connected segments of unequal length.  The output of the last flip-flop in each segment is fed back into predetermined flip-flops within that segment, such predetermined flip-flops being of a number less than the number of flip-flops in that segment.          The feedback is XORed into each such predetermined flip-flop with the output of the flip-flop that precedes the particular pre-determined flip-flop in the chain.  The first segment first flip-flop receives the XORed output of the last flip-flop in the first segment XORed with the external input, and the other of the plurality of segments first flip-flops receive their input from the last flip-flops of the just preceding segment XORed with the output from the last flip-flop in their segment.

Abstract: Abstract of the Disclosure An improved intake cup apparatus for use in an automated feeding system of the type utilizing feed supply conduits and feed conveyors providing troughs to present feed to caged poultry and the like.  The improved intake cup properly meters and directs feed from the supply conduits to the feed conveyors and assures the conveyors will not become over-filled.  The physical structure of the improved intake cup apparatus comprises a cup body having openings formed therein to receive feed from a supply conduit and allow a helical auger-like element of the feed conveyor to pass through the cup body and collect feed therefrom.  Collection of feed by the auger-like element as it proceeds through the cup is restricted however, by an open-sleeve member partially surrounding the auger within the cup body and a restrictor plate partially covering the remaining auger access.  Certain void areas are also created adjacent the auger means and thereby assure overfilling will not occur.  Deflector means and supply means are also provided within the improved intake cup apparatus to properly distribute the weight forces associated with the incoming feed and appropriately meter feed flow into the auger-like element.

Abstract: ABSTRACT OF THE DISCLOSURE    The tire crampon comprises a cross-shaped member having four arms,  interconnected by half-braces bearing bushes for connection to a vehicle's wheel hub bolts.  Counter-arms are slideable on the arms and each have a toothed sector rigidly associated  with  an  end  thereof.

Abstract: TANK GAUGE     ABSTRACT OF THE DISCLOSURE   A liquid level gauge for tanks includes a float located in the tank to follow the level of liquid in the tank.          A cable extends from the float to the top of the tank and over a pulley to the outside of the tank, where it is attached to a weight for maintaining tension in the cable.   The pulley is attached to a signal generator that generates two electrical signals.  These are lead from the signal generator to a counter which  decodes  the  two signals and produces a running count representing the height of liquid in the tank.  The preferred embodiment of the invention uses a segmented optical disk and two  phototransistors  for  producing  two  out  of phase pulsed signals.   The  number of pulses represents the magnitude of float movements, while the sequence of the phase-shifted pulses represents the direction of float movement.

Abstract: The silicone rubber adhesive film of the present invention is characterized by simplicity of handling and an excellent workability and useability, as well as by adhesiveness for various types of substrates and an excellent durability of adhesion.  These characteristics are obtained because the silicone rubber adhesive film of the present invention comprises a silicone rubber composition which consists of components (A) through (G), particularly the specific wet-method hydrophobicized reinforcing silica comprising component (C) and the specific compounds of components (D) and (E) or components (D), (E), and (F), and because the tensile strength of said uncured silicone rubber composition falls within the range of 1.5 kg/cm2 to 5.0 kg/cm2 at 25 degrees Centigrade (JIS K 6301).  Accordingly, when used on flat substrates such as textiles, glass, rubber sheet, etc., it can tightly bond the adherend partners into a single, integral body.

Abstract: This specification discloses a biocidal composition and  method, by  contacting  the  article  with  the composition  in  water.    Chlorine  dioxide  has  been suggested as a strong oxidizing agent that is especially useful to kill various microorganisms.  The solutions of this invention contain little or no chlorine dioxide or stabilized  chlorine  dioxide.    Instead  solutions are disclosed  which  exhibit  biocidal  synergism  which  is developed between the chlorite ion, the chlorate ion and chloride ion when mixed in accordance with the procedures and  in  the  ratios  described  herein.    The  instant disclosure provides for mixing various components so as to provide a "redox buffered" equilibrium of intermediate species that are effective as biocidal agents.  This is aimed  at  the  formation  of  such  intermediate  species instead of the production of chlorine dioxide as taught by  the  prior  art.    Thus,  the  present  specification discloses a composition which forms on mixing water, a source of chlorite ions, a source of chloride ions and a source of chlorate ions where the mol ratio of chlorite ions to chlorate ions is in the range from about 2:1 to about 1000:1, the mol ratio of chlorite ions to chloride ions is from about 0.1:1 to about 1000:1 and the mol ratio of chloride ions to chlorate ions is in the range from  about  0.1:1  to  about  1000:1.    The  ions  would preferably be alkali metal ions, desirably sodium.

Abstract: ABSTRACT OF THE DISCLOSURE          A wavelength stabilized light source includes a laser diode which emits a laser beam of a wavelength of 1.56 µm.  A second-harmonic generator generates a second-harmonic light of the laser beam.  The second-harmonic light enters a resonator which includes a resonance cell in which 87Rb atoms are filled.  A phase-modulated microwave is irradiated on said resonator.  The resonator outputs a double resonance signal when the wavelength of the second-harmonic light is equal to a resonance wavelength of 87Rb and the frequency of the microwave is equal to a transition frequency of 87Rb.  A first control circuit controls the microwave so that the frequency of the microwave is equal to the transition frequency.  A second control circuit controls the laser diode so that the wavelength of the second-harmonic light is equal to the resonance wavelength of 87Rb.  Thereby, the wavelength of the emitted laser beam is stabilized at 1.56 µm.
