Abstract: An internal check valve for use in a linear hydraulic motor in the form of a piston-cylinder unit including a cylinder body (38) reciprocally slidable on a piston component (40).   The piston component (40) includes a tubular piston rod (52) and a piston head (60) defining first and second working chambers (136, 140) within the cylinder body (38).  The tubular piston rod (52) includes a center tube (102) located within the piston rod (52).  The center tube (102) provides a fluid passageway (134)  through its  center which communicates with a first working chamber (136).  An annular second passageway (142) is formed by and radially between the piston rod (52) and the center tube (102).   A spring biased check valve  (116)  is positioned within the piston rod (52, 54) and is operatively connected with one of the passageways (134, 126, 130).   The check valve (116) has a valve member displaceable from a valve seat (120) by hydraulic pressure to overcome the spring bias (122, 124) and allow flow in one direction.  The center tube (102) is axially displaceable relative to the piston rod (52). Displacement is effected by end of stroke movement of the cylinder body (38) and displacement of the center tube (102) causes displacement of the valve member (116) to mechanically open the check valve.

Abstract: A double spring reset standard and spring bracket therefor particularly useful for intermediate tillage operations at depths of approximately 13 inches wherein high average draft loads are in the range of 2000 pounds.  The moment arm that the springs must resist to keep the standard from tripping during normal operation is minimized by bringing the draft force line closer to the standard pivot.  The spring bracket which must be able to resist extremely high torsional stresses is fabricated from .375 inch thick metal blanks in a single cold die operation and includes offsets and specially designed edge flanges to reduce edge stresses at the offset bends.

Title: A method and arrangement relating to press filters
Inventor: GOLTERMANN JOERGEN
IPC: B01D25/164
Filed: 1995-08-30
Granted: 2000-03-21
Abstract: The present invention relates to a method pertaining to press filters of the kind which include a plurality of press plates that can be brought towards and into mutual abutment and pairs of which form therebetween at least one pressure chamber, wherein there is formed in each pressure chamber as the aqueous suspension of solid particles is dewatered a filter cake which upon completion of the dewatering process is released from the chamber by separating the press plates so that the chamber will empty itself of its contents. The method is characterized in that emptying of the pressure chambers is achieved by permitting each press plate to pivot freely about an axis which extends generally horizontally through the plane of the plate, under the weight of the filter cake to thus release the cake. The press filter is constructed so that each press plate is able to pivot in relation to longitudinal, horizontal rails supporting the plates. The pulling devices by means of which the press plates are separated from each other are attached to only a single coupling device on each side of each press plate, the coupling device being placed on or in the immediate vicinity of the runner means, in other words in the proximity of the respective rail.

Title: Lift enhancing tip vortex generation technology
Inventor: MCCARTHY PETER THOMAS
IPC: B64C23/06
Filed: 1995-07-18
Granted: 2005-10-25
Abstract: Methods for using tip generated vortices to improve performance of foils. These methods include generating substantially streamwise beneficial vortex (74) near the outboard end (60) of a foil (82). This beneficial vortex (74) spins in the opposite direction of an induced drag vortex (62), and is used to create an upwash field (76) which neutralizes induced drag by deflecting the flow behind the trailing edge (56) at an upward angle. Upwash field (76) causes the lift vector (118) on the foil (82) to tilt forward, thereby creating a forward directed force of induced thrust upon the foil (82). Beneficial vortex (74) is also used to contain and compress the high pressure field existing along the attacking surface of the foil (82). Embodiments include a twist (66) along the span of a foil (82b), an anhedral tip droop having a divergent axis of droop curvature (86), a movable vortex flap (102), a cone shaped vortex flap network (162). Methods for reducing overall tip vorticity are disclosed.
