IPC: C08L75/04
Filed: 1993-12-14
Granted: 2003-10-21
Abstract: Disclosed is a method of insulating a surface or enclosure by applying to the surface or enclosure a polymeric foam structure of a polymer material and carbon black. The carbon black is generally uniformly dispersed in the polymer matrix in the form of discrete, individual particles substantially free of agglomeration. A preferred carbon black is thermal black. The carbon black is easily processed and integrated into the present structure, and provides a lower thermal conductivity for a given loading. Further disclosed is a process for making the foam structure. Further disclosed is an extruded, insulative foam structure of the type described above.

Title: Auxiliary vehicle current collector
Inventor: TRAPP SCOTT M
IPC: B60L5/39
Filed: 1995-09-21
Granted: 1998-10-06
Abstract: An energy collector allows flow of electrical energy between a vehicle and a rail of a railway track.   The energy collector includes  a  vehicle  mounting  device  for  mounting  the  energy collector to such vehicle; a collector shoe for sliding electrical contact on such rail; and a lever arm having a first end and a second end.  The energy collector also includes a bottom torsion unit housed within the collector shoe and connected to the second end of the lever arm.  The bottom torsion unit is disposed so that the collector shoe is forcefully and generally aligned upon such rail even as the collector shoe encounters physical deviations along a surface of  such rail.   The energy collector further includes a top torsion unit housed within the vehicle mounting device and connected to the first end of the lever arm.  The top torsion unit is disposed so that a generally downwardly oriented force is applied to and conveyed by the lever arm to and through the bottom torsion unit to the collector shoe so as to encourage contact between the collector shoe and such rail.   The energy collector additionally includes a shunt engageable at an initial end to  such vehicle and connected at a terminal  end to the collector shoe.  When a potential is applied across such vehicle and such rail, the energy collector permits electrical energy to flow from such vehicle through both the shunt and the collector shoe to such rail during both static and dynamic operation of such vehicle.

Granted: 1999-09-07
Abstract: A looper control system has a looper that is interposed between two rolling stands of a tandem rolling mill and is actuated by a hydraulic actuator; and a control calculating section for calculating a speed change rate command value of a primary rolling machine and a pressure command value of a hydraulic looper actuator so that an interstand tension and a looper height can be both controlled at target tension and looper height values, respectively, on the basis of a detected looper height value and a previously determined control gain. A resonance frequency changing section detects hydraulic flow rate of the hydraulic actuator and multiplies it by a gain to obtain a first speed change rate command value; and a damping constant changing section detects pressure in the hydraulic actuator and multiplies it by another gain to obtain a second speed change rate command value. The first and second speed change rate command values are added to a speed command value, and the total is set to the primary rolling machine speed controller.

Title: Two-way diverter check valve
Inventor: SOSZKA ADAM
IPC: F16L55/07
Filed: 1996-04-15
Granted: 2001-08-14
Abstract: A two way check valve used in a water supply system includes a hollow valve body forming a valve chamber with first and second valve seats located in this chamber. The body has an inlet and two outlet ports. A valve or gate member is mounted in the valve body and is capable of pivoting between the first valve seat and the second seat.      An elongate coil spring biases the valve member to pivot towards and engage the first seat. Water can flow under pressure from the inlet to a first of the outlet ports but not to the second outlet port. Water can flow in a reverse direction into the first outlet port and is diverted by the valve member out through the second outlet port. The reverse flow is prevented from flowing out the valve inlet.

Title: Bimodal liquid chromatography pump employing artificial intelligence logic feedback control
Inventor: WOLZE DAVID A
IPC: F04B49/20
Filed: 1995-08-02
Granted: 2000-02-01
Abstract: Flowrate in a liquid chromatography precision pump (100) employs a digital control system (128) with artificial intelligence (150). In a default flow mode, pump motor speed is controlled without using real-time pressure feedback, which speed in a pressure mode is controlled using the pump system pressure point. Pressure mode is commanded by the artificial intelligence (150) when constant displacement flow measurement time is within a desired threshold and when the higher pressure piston (34a or 34B), which is used as a constant displacement flow measurement reference, is being measured. Flow mode pressure ripple is minimized by monitoring pressure points and commanding motor (18) speed change at appropriate rotation positions of a motor shaft (24) mounted cam. In pressure mode, the artificial intelligence (150) monitors for intake cycle oscillation and optimizes a highest system pressure gain dynamically. Constant flowrate proportion is provided by activating proportioning only during a constant intake flow portion of an intake cycle.
