Patent EP-0364628-B1 (EP)
Inventor: KHODAI JOOPARY ARASTOO
IPC: B01D71/02
Filed: 1988-10-19
Granted: 1996-08-28
Abstract: A process is described for the permseparation of gases, isotopes, and liquids by permselective membranes which comprise the use of membranes of solid materials with pores having a size, shape and length resulting in a microcapillary action which causes microphase separation on the molecular level of one component of the fluid, i.e. the component with the highest throughput, and the transport of that component across the membrane by flowing through the pores resulting in a complete or substantially complete separation; said permseparation depends on the difference between the bulk properties of the components. The observations leading to the present invention such as large separation factors between hydrogen and helium, and hydrogen and air, and permseparation of butanol and water as well as special and general procedures of how to carry out the present invention which relates to all areas of science and technology concerning the separation by membranes are described. This also include improved methods of producing nuclepore microfilters.

Title: Combustion fluid flow intake and exhaust valves
IPC: F01L3/20
Filed: 1988-12-16
Granted: 1992-12-02
Abstract: Improved intake and exhaust valves for an engine or the like for more efficient fluid flow into a cylinder and the exhausting of spent fluid therefrom. The valves of the present invention have the same general configuration of the valves of a conventional internal combustion engine except that the verticle circumferential portion of the valve head (margin) (20) is differently configured. A curvilinear (Coanda effect) surface (18) is employed on the intake valve between the stem side edge of the margin portion of the valve head and the valve seat and a sharp 90 degree edge is formed at the joinder of the margin (20) and valve face (Feuling effect). The exhaust valve employs the Coanda effect curved surface portion at both the joinder of the back surface of the valve and the valve seat as does the intake valve and further employs this curved surface at the joinder of the valve face and margin of an exhaust valve. In both the intake and exhaust valves the margin (20) of the valve is substantially twice the length of the generally accepted maximum allowable length (Feuling effect). This increased vertical margin surface may be accomplished in several ways, namely, by an increased width valve head thickness with a recessed valve head face (26) or an increased valve head thickness alone without the recess. In the recessed valve head face embodiments the recess can begin at the valve head surface from either a curvilinear or rectilinear edge cut spaced from the margin. The rectilinear edge cut provides for improved heat dissipation.

Abstract: The invention relates to a method for applying a molybdenum coating by thermal spraying. In known methods, substantial restrictions in carrying out the method and hence also quality defects in the layer produced must be accepted because of the high melting point of molybdenum. In the method according to the invention, in which the coating is produced by flame spraying or high-speed flame spraying with a pre-oxidised or partially oxidised molybdenum spraying material, the said disadvantages are overcome and higher qualities are achieved.

Abstract: In order to improve the adhesive strength of metal/plastic composite systems, it is known to apply silane solutions to pretreated metal surfaces. The solutions used are expensive, the special processes are complex, and the surfaces treated in this way require immediate further processing. Pretreated alloy surfaces are   - either blasted with amorphous quartz powder, etched with hydrofluoric acid, rinsed with distilled water and coated with an adhesion promoter before the plastic is applied; - or the alloy surface is either moistened with silane solution and blasted with quartz sand (particle size 20-500  mu m), or blasted with silanised quartz powder having a particle size of 20-500  mu m, - or sprayed with silane solution and simultaneously blasted off with amorphous quartz powder (particle size 20-500  mu m). The surface pretreated in this way is coated with a known adhesion promoter (coupling agent), preferably at a reduced pressure of 1-50 Pa, and the plastic is applied thereto. The process is suitable for the production of a reliable bond with high pressure shear strength of plastics to metals.
