Title: Drive/frame assembly for a reciprocating floor
Inventor: FOSTER RAYMOND K
IPC: F15B15/14
Filed: 1987-09-04
Granted: 1993-04-06
Abstract: Abstract of the Disclosure Piston rods  (60,  62)  of  three  linear  hydraulic  motors (36,  38,  40) are connected at their outer ends (64, 68)  to two  spaced  apart  transverse  frame  members  (10,  12).   A cylinder housing  (72)  is driven back and forth along each pair of piston rods (60, 62).  Three transverse drive beams (48, 50, 52) are provided.  Each drive beam (48, 50, 52) is directly  connected  to  an  associated  one  of  the  cylinder housings  (72).  Three sets of floor slat members (1, 2, 3) are  provided.   Each  set  (1,  2,  3)  is  connected  to  an associated one of the transverse drive beams (48,  50,  52). The linear hydraulic  motors  (36,  38,  40)  are operated  for moving the floor slat members  (1,  2,  3)  in one direction, for  advancing  a  load,  and  for  retracting  them  in  the opposite  direction.   Each  cylinder  housing  (72)  has  four fluid  chambers  (82,  84,  86,  88).   The  first  and  third chambers  (82,  86)  are  interconnected  and  the  second and fourth   chambers   (84,   88)   are   interconnected.    This arrangement provides an adequate force producing area with a  relatively  small  diameter  cylinder  housing  (72).   Fluid passageways  (110,  112)  are formed in the piston rods  (60. 62).   Transfer valves  (138,  140)  and U-shaped  tubes  (134, 136,  126,  128)  are clamped onto the outer end portions of the piston rods (60, 62) by means of a pair of clamp plates (190,  192,  214,  224)  and  interconnecting  nut  and  bolt assemblies (194, 226).

Abstract: ABSTRACT      A transposable dual mode mailbox  signaling device for mounting on either side of a rural mailbox is disclosed.  A housing attachable to either side of a mailbox proximate the mailbox  door has  a  front  face,  back  face,  a proximal  end, including a centered elongated aperture to receive a flagstaff flange,  and an open distal end, an open top edge and an open bottom edge.  A longitudinally symmetrical flagstaff is mounted within the housing for pivotal movement about its horizontal axis.  The flagstaff has an opposing pair of horizontal flanges at the lower end as well as a downward projecting flange at the flagstaff's lower edge.  Each flange is sized to fit through the proximal edge's aperture.  A longitudinally symmetrical flag is attached  to  the  flagstaff's  other  end.    A  reversible  rod attachable  to a mailbox door  includes a detent to retain a corresponding horizontal flange when the flag is up.  When the rod  to  retain the horizontal  flange in place  is removed by opening  the mailbox  door,  the  flag  falls  approximately  180 degrees  by  gravity  until  engaging  the  proximal  end.    An alternate embodiment includes a reversible and a disengageable stop   proximate  the  distal  end  to  retain  the  flag  at approximately 90 degrees.  Another alternate embodiment includes a leaf spring to aid the gravity fall.

Abstract: "IMPROVED CATALYST FOR TREATMENT OF EXHAUST GASES          FROM INTERNAL COMBUSTION ENGINES"                        ABSTRACT           This invention relates to a catalytic composite for treating an exhaust gas comprising a support which is a refractory inorganic oxide having dispersed thereon lanthanum, at least one other rare earth component and at least one noble metal component selected from the group consisting of platinum, palladium, rhodium, ruthenium and iridium.  An essential feature of said catalytic composite is that the lanthanum be present as crystalline particles of lanthanum oxide which have an average crystallite size of less than about 25 Angstroms.  The support may be selected from the group consisting of alumina, silica, titania, zirconia, aluminosilicates and mixtures thereof with alumina being preferred. Illustrative of the other rare earth components are cerium, neodymium, praeseodymium, dysprosium, europium, holmium and ytterbium.  This invention also relates to a method of manufacturing said catalytic composite.  In particular, an important feature of said method of manufacturing is the dispersion of lanthanum oxide onto said refractory inorganic oxide support.  In a specific example where the refractory inorganic oxide support is alumina, the lanthanum may be dispersed on the alumina as follows.  A solution of a lanthanum salt is mixed with a hydrosol of aluminum, particles are formed from said lanthanum containing hydrosol, calcined to form an inorganic oxide particle containing lanthanum oxide, ground to give a powder of alumina containing finely dispersed lanthanum oxide.  This powder in turn can be mixed with another rare earth oxide such as cerium oxide to form a slurry which in turn is used to coat a solid monolithic carrier.  Finally, at least one noble metal component is dispersed on said coated solid monolithic carrier.

The motion of the joint includes a minor  segment  from  the  extended  position  to  the intermediate position, and a major segment from the intermediate position to the flexed position.   The center of pressure between the femoral component and the  tibial  component moves  rearward on the  tibia during the minor segment.  During the major segment, the joint flexes about an axis of rotation with the bearing surfaces on the femoral and tibial components being in congruent engagement.  The distal surface of the  femoral  component  includes  two  rails  for engagement with a patellar prosthesis.  The contour of the rails is either a straight line or a concave curve to provide line contact between the rails and the patellar prosthesis.  In certain embodiments, the patellar prosthesis has a saddle-shaped surface so that the prosthesis and each of the rails can make contact over an area extending along the length of the rail.

Abstract: Abstract of the Disclosure A control circuit (16) mounted on a faucet (10) operates an ultrasonic transducer (20) that transmits ultrasound into a target region (22) below the outlet (24) of the faucet.  The control circuit receives electrical signals from the transducer when the transducer receives echoes from objects within the target region.  The control circuit times the echoes to determine the distance of the object causing the echoes, and, if the distance of the object changes between successive measurements, the control circuit operates a valve (12) to permit water to flow.  The circuit is powered by a rechargeable battery (18) that is charged by the action of a generator (31) that is driven by a turbine (34) powered by the flow of water through the faucet.
