Abstract: DRUM FILTER          ABSTRACT OF THE DISCLOSURE     A drum filter is disclosed mounted vertically within a tank which receives the liquid to be filtered. The drum is provided with inside and outside filter media layers and intermediate axially extending passages receiving filtered liquid flow, which is collected in a central tube extending vertically upward and adapted to be connected to a suction pump.          A backwash arrangement includes a backwash flow passage directing flow successively through each of the axial passages as the drum is incrementally rotated about its axis.          Collection troughs are positioned extending axially along the inside and outside periphery of the drum member so as to receive the backwashing flow and contaminants, with a flushing flow carrying off the contaminants from the tank for secondary filtration.          The rotary indexing drive consists of a cylinder actuated ratchet drive with a sprocket wheel in engagement with a chain track located about the interior diameter of the drum member at its upper end.          A surrounding shroud extends about the periphery of the drum member in some embodiments which ensures that the filter media layers are covered with liquid even if the liquid level in the tank declines below the level of the upper section of the media layers.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for cutting scrap tires and other waste products is disclosed. The apparatus includes a frame having a cylindrical anvil roll rotatably mounted therein. A pair of blade rolls are also mounted in the frame for rotation about corresponding axes which are parallel to the rotational axis of the anvil roll, the blade rolls being angularly spaced from one another relative to the axis of the anvil roll and being positioned about the periphery of the anvil roll. The blade rolls are each provided with a plurality of blades of predetermined diameter fixed thereto and rotatable therewith, the blades of one blade roll being at a low angle to the axis of that roll and the blades of the other blade roll being at a high angle to the axis of that roll, so that a tire passing between both blade rolls and the anvil roll will be cut into rhomboidal pieces that are nearly rectangular in shape during a single pass through the apparatus. The blade rolls are each also provided with a pair of axially spaced thrust wheels, with the thrust wheels being positioned outboard of the blades and being equal to or slightly greater in diameter than the predetermined diameter of the blades. Driving means are provided in the apparatus for rotating the anvil roll in one direc-tion and the blade rolls in an opposite direction. Biasing means are also provided for forcing the outer peripheries of the thrust wheels and the anvil roll into hard contact with one another thereby to maintain fixed the spacing between the cutting surfaces of the blades and the outer surface of the anvil roll notwithstanding the separating forces caused by the movement of a tire between such surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE            A  piston ring is formed from a plastics material  and has a maximum pressure against the associated cylinder of  between  0.10 and 1.50 MN/m2 and  preferably  0.50 MN/m2.  One possible material for such piston rings is polyetheretherketone.    The  benefits  obtained   are greater  conformability which leads to a reduction  in the  number  of piston rings which need be used for  a particular piston.   This in turn reduces friction  so increasing  the performance of the associated  engine.          Acceptable   wear  rates  and  ability  to   withstand operating temperatures have been found in these piston rings.     Fig. No. 8

Abstract: Abstract of the Disclosure An extrudate catalyst suitable for auto emission control is made from a solid, transitional alumina with a partially hollow interior and one or more platinum group metals deposited on the extrudate.  Further deposited can be ceria as a promoter either alone or in combination with an alkali metal which is more preferably in the oxide form as lithia.  The cylindrical extrudate has internal reinforcing vanes or ribs extending from the inner wall to the center of the extrudate particle.  This configuration permits the catalyst to have the large geometric surface area per reactor volume yet, because of the openings inside the extrudate, the catalyst particles do not exhibit a large pressure drop when packed in a deep bed.          These catalysts provide greater hydrocarbon and carbon monoxide conversions than do similar size spherical particles and they have improved light-off characteristics.

Abstract: Abstract of the Disclosure A logic  system preferably  for gallium arsenide integrated  circuits  uses  dynamic  pulsed  logic  gates which  switch  on  each  clock  pulse,  with  the  logical state of an output or data line being indicated by the phase  of  the  pulsed  output,  which  may  be  shifted  or modulated  with  respect  to  a  reference.   An  individual logic  gate has  a first signal generator having a capa-citor which is either charged up or discharged during a set-up  phase  of  a  clock cycle,  depending upon applied input  logic  signals.   During  a second,  transmit phase of the  clock signal,  the signal developed on the capa-citor is output from the gate.  A second signal genera-tor is an inverting slave of the first,  and outputs the inverse  logic  state  during the  succeeding set-up phase of the first generator.          With   each   gate   switching   on   every   clock period,  all  switching noise  appearing in the ground or power  supplies  is  at or  above  the  clock frequency and can simply be  filtered out with small chip capacitors, providing improvements in noise immunity.          The  logic  is preferably  implemented in gallium arsenide metal  oxide  semiconductor technology,  with the capacitors  formed  from  reverse-biased  Schottky  diodes, and  all  FET  switches  capacitively  coupled  and  self biased.

Abstract: ABSTRACT OF THE DISCLOSURE     A transmission that uses a gear set  in  the  form  of  a pair  of  gears  stacked  rigidly together to couple a driving gear to  a  driven  gear  has  its  ratio  determined  by  the relative  number  of  teeth of the stacked gears and the gears with which the stacked gears mesh.  If  the  number  of  teeth of  either  or  both gears in the stack is varied, the axle of the stack must be moved to a different location  in order  to keep  all  of the pairs of gears meshed.  The transmission has two or more axle-receiving locations to receive the  axles  or stacks  effecting  different  ratios.    To simplify assembly, the stacks  are  color-coded   according  to  the  ratios  they effect.    Stacks  of  the  chosen  color will only fit in one axle location.  The selected stack  may  be  enclosed  in  the transmission  housing  so  that  its  color  code  will not be visible after assembly of the transmission.  In  order  to  be able to   identify   the   gear   ratio   of   an  assembled transmission,  another  transmission  component,  such  as  an axle,  which  is installed in the assembly at a location where it may be  seen  from  outside  the finished transmission,  is also color-coded in the same way as the gear stack.
