Title: Stable aminoplast cellular foams and process for manufacturing them
Inventor: MAEDER KARL JOZEF
IPC: C08J9/00
Filed: 1991-03-18
Abstract: Abstract Stable, emission-free, low-shrinkage, fireproof aminoplastic cellular foams are obtained by using an unsaturated, halogenated polyalcohol in the resin precondensate constituent and a dodecyl-benzolsulphonic acid partially esterified preferably with a fatty alcohol and a long-chain polyhydric alcohol, preferably a polyethylene glycol, in the foaming agent hardener constituent.  The foams are particularly suitable for building construction and for covering, as well as in the agricultural sector and or oil absorption.  For certain of these applications, the resin pre-condensate constituent of the invention can be processed with a conventional foamer hardener constituent or the foamer hardener constituent of the invention can be processed with a conventional resin precondensate constituent.

Title: Fluid containment article for hot hydrocarbon fluid and method of preventing fuel thermal decomposition deposits
Inventor: COFFINBERRY GEORGE A
IPC: C23C16/40
Filed: 1992-02-27
Abstract: Dkt. No. 13-DV-10367 ABSTRACT OF THE DISCLOSURE            Fluid containment article for hot hydrocarbon fluid wherein the surface for contacting the fluid is a diffusion barrier material coated on a substrate.  The diffusion barrier layer is either catalytically-inactive and inhibits the formation of hydrocarbon thermal decomposition products in the fluid or catalytically-active and promotes the formation of a loosely adherent coke in the fluid while inhibiting the formation of other thermal decomposition products in the fluid.  Preferred catalytically-active and catalytically-inactive diffusion barrier materials are amorphous metal oxides, such as zirconium oxide and tantalum oxide respectively, deposited as a liner on the surface of a metal substrate.  The fluid containment articles find utility in components subjected to high temperatures and using hydrocarbon fluids without additives, without special attention to quality control and without the need for special processing.
Patent CA-2064573-A1 (CA)
Title: Quick drop valve
Inventor: SMITH DAVID P
IPC: E02F3/85
Filed: 1990-10-15
Abstract: Abstract of the Disclosure QUICK DROP VALVE           Quick drop valves are usable in hydraulic circuits in which fluid is expelled from a hydraulic cylinder due to gravity force acting on a load connected to the hydraulic cylinder.  The present quick drop valve (10) has a sleeve (68) carried by a valve member (42) for establishing an orifice (66) through which the fluid expelled from the hydraulic cylinder (13) passes.  When the flow rate of the expelled fluid exceeds a predetermined flow rate, a differential pressure generated by the orifice (66) causes the valve member (42) to start moving toward a quick drop position.  In so doing, the sleeve (68) quickly establishes a more restrictive orifice (67) to immediately generate a higher differential pressure to cause the valve member to quickly move to the quick drop position.  The more restrictive orifice also causes a greater amount of the expelled fluid to be returned by the valve member to the expanding ends of the hydraulic cylinders, yet still allows sufficient flow therethrough so that the quick drop action can be stopped if so desired.  The sleeve also functions similar to a check valve and moves to a position permitting substantially unrestricted fluid flow through the quick drop valve when the fluid is being directed to the hydraulic cylinder to raise the load.          An actuating chamber (61) is defined in the valve member (42) and is subjected to pressurized fluid generated in the circuit to hold the valve member (42) in a blocking position when the blade is forced into the ground.

Patent CA-2079365-A1 (CA)
Title: Check valve for fluid bladders
Inventor: PEKAR ROBERT W
IPC: F16K15/00
Filed: 1992-09-29
Abstract: A check valve provides a one-way fluid passage from without to within a fluid bladder formed by a pair of plastic sheets sealed together about their periphery. The check valve is formed by a pair of superimposed films of thermo-plastic material, generally equal in length, thermally bonded together at predetermined areas to define the fluid passage throughout the length of the valve. Each of the films, adjacent one end thereof, is sealed to one of the outer sheets where the valve enters the bladder by a seal line of wedge shape. Each of the films has a high-gloss, cohesive inner surface and a matte, non-cohesive, outer surface. At least one of the films includes, on its inner surface, a release material disposed at a location which corresponds to the area at the inlet end of the fluid passage through the peripheral seal of the bladder to prevent the fusing together of the films at that area of the seal. The seal in that area has a V-shape with apex pointing in a direction opposite the one-way fluid flow. The terminal ends of the superimposed films extend in surface-to-surface relation-into the bladder to provide a "duck-bill" type check valve.

ABSTRACT   This invention is an air purifier pleated flat filter to be installed in passenger motor vehicles to stop pollution for passengers inside of the motor vehicle.  This filter will cleanse the air which is pulled by the blower from outside the motor vehicle and/or the existing air polluted by passenger inside the motor vehicle. It also absorbs the odors and emissions from the air conditioner.  This filter prevents pollutants, which are emitted from the exhaust fumes of the motor vehicles, as well as hydrocarbons, odors, smoke, soot, dust and all kinds allergens-pollen from polluting the air which enters the motor vehicle interior.  The pleated filter is preferably installed in the plenum of the vent which is connected to the cowl plenum chamber or in the plenum of cowl plenum chamber of the vehicle's heating-cooling system.  The filter is also preferably equipped with a sensor switch that notifies the driver whenever the filter becomes dirty and must be replaced.  The filter includes a hot fluid heater, such as a hot water heater, which protects the filter from freezing and keeps the filter dry which stops bacteria from multiplying and prevents odors.  This purified fresh air is important to people with emphysema, asthma and all kinds of allergies.  By installing the pleated flat filter in motor vehicles, we can be assured of breathing purer air.
