Title: Fluid pressure control valve and a system which includes such a valve
Inventor: HEDDERICK JOHN B
IPC: B67D1/12
Filed: 1988-04-29
Granted: 1991-12-17
Abstract: ABSTRACT A fluid pressure control valve and a fluid control system (such as for beverage dispensing) with such a valve has a beverage passage 3, pressure fluctuations in which are detected by a diaphragm 17 to displace a sensing member 15 axially against spring loading 23.   Spring 23 reacts on thrust member 22 which is adjustable axially through a cam mechanism 25/26 to vary the biasing force of spring 23.   A valve member 20 spring loaded at 21 relative to thrust member 15 normally closes an exhaust port 19 to an air or other gas passage 5 through which gas passes under pressure to be injected into the beverage from passage 3.   An increase in beverage pressure in passage 3 displaces sensing member 15 to increase the spring biasing 21 on the closure member 20 and reduce the proportion of air which can escape to atmosphere from passage 5 through exhaust port 19 to provide an increase in air flow into the beverage. A reduction of pressure in passage 3 reduces the spring biasing 21 to permit a greater proportion of air to escape from passage 5 through exhaust port 9 and thereby reduce the proportion of air which is introduced into the beverage.     The control valve can include a temperature sensitive unit responsive to temperature of beverage in passage 3 and which reacts to adjust the force of biasing spring 21 independently of pressure in the passage 3.     Plunger 51 can be depressed manually to close the exhaust port 19 temporarily and thereby maintain maximum air pressure in the passage 5.

Inventor: STIEF THOMAS
IPC: C12Q1/56
Filed: 1988-06-30
Granted: 1996-10-29
Abstract: The invention relates to a method for the determination of the activity of serine proteases and serine protease inhibitors in plasma or other biological fluids.            The only methods hitherto available for rapid and accurate determination of the content of serine proteases or serine protease inhibitors have been very time-consuming and methodologically demanding.  In the method according to the invention for the determination of the activity of serine proteases or serine protease inhibitors, specific inhibitors are inactivated by addition of at least one oxidizing agent and, where appropriate, at least one detergent.  The addition of an omega-aminocarboxylic acid enhances the observed effects when the serine protease is plasmin.

Abstract: A piston-type portable sample cylinder is provided suitable for obtaining and transporting a liquified petroleum gas sample taken from a flow line.  A piston slidable in a cylinder creates an increasing volume for the sample, and displaces an opposing inert gas maintained in the sample cylinder at a preset pressure.  A toroidal mixing element has an outer diameter approximating the inner diameter of the cylinder, and slides over a cylinder projection on the piston to minimize voids when the sample cylinder is empty.  The piston may be provided with a selectively adjustable seal for maintaining sealing integrity over a long life, with or without the use of lubricants.  Magnets on the piston for activating external magnetic trip flags may be contained in a nylon protec-tor ring.  Precision fill measurements may be obtained from a sight gauge including a biased coiled tape mounted within the pressurized inert gas cavity of the sample cylinder and secured to one end of the piston.

Title: Means for preventing skin abrasions for patients having legs substantially locked in juxtaposition
Inventor: LONARDO ROBERT
IPC: A61F13/00
Filed: 1988-10-12
Granted: 1993-01-26
Abstract: ABSTRACT    The method of this invention pertains to preventing skin abrasions and the like in patients whose legs are substantially locked together in juxtaposition.  The method comprises the tak-ing of an elongated flexible planar pad with a length extending from above the patient's knees to the bottom of the patient's foot.  The width of the pad is approximately one-half of the girth of one of the patient's legs.  The pad is placed between the patient's legs so that the opposite sides of the pad cover the inner surface of at least one leg from a point above the knee to a point substantially to the bottom of the foot of one leg. The pad is affixed to one leg of the patient at points above the knee and above the ankle of one leg to hold the pad against any substantial movement with respect to the one leg.  The apparatus of this invention comprises a pad for the foregoing method.  The pad is a flexible planar pad having a top, bottom, side edges, and opposite leg engaging surfaces.  The leg engaging surfaces comprise a soft resilient material so that the skin and flesh of the inner portion of a patient's legs will be protected from abrasive action.  A first strap means is secured to the pad adjacent its upper end for securing the pad to a patient's leg just above the knee.  A second strap means is secured to the pad adjacent the bottom thereof for securing the pad to the patient's leg just above the ankle.
