Title: Iron surface treatment - by plasma discharge causing formation and decomposition of nitrides and carbides
IPC: C23C8/38
Filed: 1971-10-06
Abstract: The surface properties of Fe or steel are improved by passing intensive electric discharge through effluvia produced at high temp. in an atmosphere containing substances which can diffuse, e.g. N and C, the discharge being regulated in such a way that on the substrate is formed a diffusion layer of several levels whose interior combination zone (A) which is free from pores and has monophase composition, is maintained at the prescribed thickness by constant partial decomposition the pptn zone (B) which succeeds (A) being, by decarburisation, maintained free from lattices and lines of nitride next to the surface; the discharge is regulated by selection of the nature, quantity, and energy of the ions striking the surface so that by virtue of the nature and quantity of expelled elements, appropriate reactions take place at the limiting plane between the gaseous plasma and the surface. Surface has improved resistance to fatigue due to alternating load, and to wear and better sliding properties and corrosion resistance.

Title: Polyphenyl ethers - with increased melt viscosity index, by adding precipitant throughout the polycondensation reaction
IPC: C08G65/44
Filed: 1972-08-01
Abstract: During polycondensation of phenols under the action of oxygen in presence of catalyst, in solvent/precipitant systems, the content of precipitant is varied during the reaction in the range of 0.1 to 10 vols. per vol. solvent, depending on the mol. wt. of end- product required. A typical phenol used is 2,6-dimethyl phenol, suitable solvents are aromatic hydrocarbons and nitro-, amino- and halogen derivs. of aromatic or aliphatic hydrocarbons. Precipitants are aliphatic and cycloaliphatic, hydrocarbons, alcohols, ketones, amides, ethers or mixts., and they may be added continuously or in portions during the reaction. Melt viscosity is reduced and melt viscosity index increased to a multiple of that of polymers of similar mol. wt. obtained by conventional methods, giving improved processability with maintenance of the high physical and chemical properties. A separate precipitation step is eliminated.

Title: Valve for fluid media - shape of closure member prevents fluid induced vibration
IPC: F16K47/04
Filed: 1974-07-23
Abstract: The valve has a tapered body which is adjustable axially in an opening in the fluid passage. The valve body is so asymmetrically shaped on its side facing the valve seat of the opening that the medium impinging upon the body exercises a force upon the body perpendicular to its axis of displacement which is greater than the perpendicular forces of vibration, and thus stabilises the position of the body in the fluid stream. The asymmetry is produced by a projection which is eccentric to the axis of displacement and whose ratio of eccentricity to the diameter of the opening lies between R = D/6 and R = D/4.

Title: Pipe union without screw threads - has internal sleeve expanded by pressure on destructible diaphragms in rings forced along tapering bores
IPC: F16L21/00
Filed: 1975-09-05
Abstract: An internal sleeve (1) consists of a central section (3) of the same outside dia. as the pipes (20, 21) and two end sections, which have outside dia. slightly less than the inside dias. of the pipes. The sleeve has two slightly conical bores contacting as the axial distance from the centre increases and ending in inturned flanges (9, 11). Slightly conical rings are inserted in each branch of the bore and each is fitted with a thin closing diaphragm. A tapping (17) in the sleeve gives access to the space between the rings. To make the joint, either fluid pressure applied to the tapping, or an explosive charge is used to force the rings apart. This in turn expands the ends of the sleeve until they grip the pipes internally. The diaphragms may be water soluble or inflammable so that they can easily be destroyed when the joint has been made.
