Abstract: The present invention is an element for gripping metal to be stretched by a stretcher leveler apparatus. The gripping element includes a first and preferably a second high density cast polyurethane gripping pad adapted for engagement with the metal to be stretched and a support member which can be a rectangular plate upon which the first and second gripping pads are operatively anchored. The support member having two pads is detachably mounted to the stretcher leveler apparatus either in a first orientation in which the first pad is positioned for engagement with the metal to be stretched or a second orientation in which the second pad is positioned for engagement with the metal to be stretched.      Preferably, the support member is a plate having a first support surface upon which the first gripping pad is chemically bonded and a second support surface upon which the second gripping pad is chemically bonded. The support surfaces are disposed on opposite sides of the plate and in a parallel relationship. The gripping pads are preferably cast in situ on the support member.      Preferably, at least one threaded hole is disposed at either end of the support member for allowing attachment to the stretcher leveler apparatus with threaded fasteners.

Abstract: A brake shoe for engagement with the tread of a railway car wheel having a tread conditioning agent incorporated in the composition friction brake shoe material of the brake shoe block for altering the adhesion between the wheel and rail on which the railway car is guidably supported. The tread conditioning agent is a material that is dissimilar from the composition friction material of the brake shoe block, being chosen in accordance with a lubricating quality or an abrasive quality depending upon whether the brake shoe use is intended to reduce or increase wheel/rail adhesion. In either case, the chosen conditioning material has a wear rate that exceeds that of the composition friction material so that the degree of conditioning is controlled by the wear rate of the composition friction material and the percentage of brake surface of the brake shoe block occupied by the conditioning material.

Granted: 2002-04-02
Abstract: This invention provides a method of and compositions for increasing or maintaining glomerular filtration rate while pre-serving renal structure in a patient comprising administering an angiotensin II type 1 vascular receptor antagonist to the patient, independent of its effects on systemic blood pressure. The invention provides that, by administering the AII type 1 receptor anta-gonist, blood flow to the kidney can be improved without sacrificing intraglomerular pressure and therefore glomerular filtration and that even with this enhanced glomerular pressure and filtration, renal structure is preserved. Also provided is a method of screening AII type 1 receptor antagonists for the ability to maintain or increase glomerular filtration rate while decreasing mesan-gial matrix accumulation comprising the steps of administering the antagonist in an animal model characterized by decreased glomerular filtration rate and increased mesangial matrix accumulation and selecting the compounds that increase glomerular fil-tration rate while decreasing mesangial matrix accumulation.

Title: High speed thermomechanical actuator
Inventor: SCHNEIDER EDWARD T
IPC: B25J15/00
Filed: 1994-01-10
Granted: 2004-06-15
Abstract: A heat sink (14) provides thermal communication between an actuator (18) and fluid controlled by a valve (12) which is flowing through a conduit (10). The actuator includes a vessel which is defined on its largest surfaces by plates (22, 50) of beryllium oxide thermally conductive ceramic covered with thermally conductive, relatively electrically nonconductive nichrome foil (24, 26). Longitudinal sides (30, 32) of the vessel are also relatively non-conductive. A thermally and electrically conductive core, such as accordion pleated beryllium copper foil (44) or a carbon fiber mat (82, 116) is disposed in the chamber.  Electrical current flows through the core itself (Figure 4) or through electrically insulated heating wires (80)(Figure 5) or through an electrically insulated heating surface layer (Figure 6) causing resistance heating and melting of a non-gaseous polymeric phase change compound (46). The resistance heating current is inductively induced in the embodiment of (Figure 8). The polymeric core material expands transferring force through a rubber core (66, 108) to a push pin (68, 130). Fluid flowing through the conduit (10) draws heat from the phase change material through the core, the vessel, and the heat sink to solidify the phase change compound, causing the push pin to be retracted. The phase change compound is selected and the actuator is sized to achieve an actuation time of less than 500 milliseconds.

Abstract: An assembly for applying a solid material, such as a lubricant or an anti-slip material, to wheels.  The system includes a pair of spring actuated members located on opposite ends of a holder for the solid material to urge the holder upwardly along guide pins to force the solid material to contact a wheel as it passes over a rail and the solid material element.  The solid material element is held or "pinched" between the wheel flange and the gage face of the rail, thereby applying the material to the wheel which, in turn, transfers the material to the rail surface.   The upward motion of the solid material  is counteracted by a braking arrangement, including a brake release, so that a wheel passing over the release, releases the braking arrangement to allow the solid material to move upwardly to contact a wheel.

Title: Pivoting valve assembly
Inventor: ROBERTSON WALTER D III
IPC: F16K31/10
Filed: 1996-05-21
Granted: 1999-12-07
Abstract: An adjustable pivot valve assembly (10) for use in a fluid flow system (S). A valve body (12) has a fluid flow path therethrough and includes an inlet (14), an outlet (16), and a valve orifice (18) formed intermediate the inlet and outlet.  A valve seat (28) is mounted for movement relative to the orifice to open and close the fluid path.  The valve seat is attached to a valve stem (30). A solenoid assembly (50) is supplied with an input from a sensor/control unit (S) to effect movement of the valve seat. What would otherwise be a linear movement of the valve stem and valve seat is translated into movement of a plunger (78) interconnected with the valve stem to produce a movement which is orthogonal to a longitudinal axis of the valve stem. This translated  movement causes the valve seat to pivotally move about the orifice to effect an opening of the orifice for fluid to flow between the inlet and outlet.  The valve stem, plunger, and a pole piece (56) of the solenoid comprise a lever arm the length of which is adjustable to vary the force required to effect the pivoting movement.  A spring arrangement (86a, 86b) centers the valve stem and seat, and a spring (46) biases the valve seat toward a position closing the orifice.  Stops (90a, 90b) located on opposite sides of the plunger, at the end of the arm remote from the valve seat, limit the orthogonal movement of the valve stem.

Title: System for providing prioritized connections in a public switched network
Inventor: GARLAND STUART MANDEL
IPC: H04M3/00
Filed: 1996-07-29
Granted: 1999-12-28
Abstract: The invention uses a suppressed ringing connection, switched through the existing call processing switch fabric, to connect two CPEs for long duration, low priority calls. The suppressed ringing connection is implemented such that the connection is disconnected if an incoming call to one of the CPEs or an outgoingrequest for service from one of the CPEs is made. If the suppressed ringing connection is disconnected due to a request for normal service to or from one of the CPEs, the system of the invention automatically reestablishes the suppressed ringing connection after the normal service call has ended such that the long duration suppressed ringing connection can be maintained on a quasi-permanent basis. As aresult, the suppressed ringing connection can be maintained for long duration connections without disrupting normal incoming or outgoing service to either of the connected CPEs.
