Title: New polyol ester derivatives of polyamines and use in turbine oils to improve cleanliness
Inventor: BESSONETTE PAUL W
IPC: C07C233/36
Filed: 2003-02-26
Granted: 2014-04-22
Abstract: This invention generally relates to new polyol ester derivatives of polyamines for use as dispersant additives compatible in synthetic ester-based turbo oils. The dispersant additives of the present invention consist of a hydrocarbon acid, a polyol, an amine carrier such as diacid or cyclic anhydride and a polyamine. The hydrocarbon acid makes up the non-polar hydrocarbon portion of the dispersant and the polyamine functions as the polar headgroup. The diacid or cyclic anhydride provides a means for attaching the polar polyamine to the dispersant structure through an amide linkage. Different dispersant structures are obtained by varying the hydrocarbon acid, the polyol and the nature of the polyamine.

Abstract: A system to feed cooling air to a gas turbine, wherein the cooling air is taken from a high-pressure source, inside the gas turbine, and is conveyed to radial accelerators (12), which give rise to the tangential acceleration of the air in the direction of the peripheral motion of the rotor surface. After it has been accelerated to the peripheral sepped of the rotor, the cooling air enters radial holes (13), and, whilst passing radially through the radial holes (13), undergoes a reduction in the quantity of tangential motion, Subsequently, the cooling air is released into the hollow rotor, with a correspondingly reduced outlet radius (14). A series of labyrinth seals combined with brush seals separate the chamber for combined with brush seals separate the chamber for feeding of air to the radial holes (13), from the low-pressure environment around the pad #2 (15) of the said gas turbine.

Abstract: A disposable syringe includes a plunger movable in a barrel relative to a needle seat that engages an inner surrounding barrel wall surface of the barrel by a resisting force. The plunger includes a plunger body and a coupling rod which is in frictional engagement with the plunger body and which has a central anchored area disposed to engage an anchoring portion of the needle seat by a holding force. As such, when the plunger body is moved to bring the central anchored area into engagement with the anchoring portion, the resisting force is overcome to permit disengagement of the needle seat from the barrel, and the coupling rod and the needle seat can be retracted into the plunger body by virtue of a biasing action of a biasing member.

Title: Method for reducing emissions from evaporative emissions control systems
Inventor: HILTZIK LAURENCE H
IPC: F02M25/08
Filed: 2002-07-08
Granted: 2007-01-09
Abstract: Disclosed is a method for sharply reducing diurnal breathing loss emissions from automotive evaporative emissions control systems by providing multiple layers, or stages, of adsorbents. On the fuel source-side of an emissions control system canister, high working capacity carbons are preferred in a first canister (adsorb) region. In subsequent canister region(s) on the vent - side, the preferred adsorbent should exhibit a flat or flattened adsorption isotherm on a volumetric basis and relatively lower capacity for high concentration vapors as compared with the fuel source-side adsorbent. Multip le approaches are described for attaining the preferred properties for the vent - side canister region. One approach is to use a filler and/or voidages as a volumetric diluent for flattening an adsorption isotherm. Another approach i s to employ an adsorbent with the desired adsorption isotherm properties and t o process it into an appropriate shape or form without necessarily requiring a ny special provision for dilution. The improved combination of high working capacity carbons on the fuel source-side and preferred lower working capacit y adsorbent on the vent-side provides substantially lower diurnal breathing emissions without a significant loss in working capacity or increase in flow restriction compared with known adsorbents used in canister configurations f or automotive emissions control systems.

Abstract: Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate. Also disclosed are dry compositions comprising a hydratable cementitious binder, a mechanical foam stabilizing agent, and optionally a fibrous component, set retarder and air entraining agent, said composition providing, on the addition of water, gas and mechanical turbulence, a settable foam which is capable of spray application to a steel structural member and which, after spray application, is adherent to the member in the foamed state and after setting. The foam after setting, forms a fire and heat protective adherent coating on the member.
