Rotary compressor including at least one rotor (2), which is rotatably mounted in a compression chamber (1) by liquid lubricated bearings (4), a device (13-15-16) for injecting water into the compression chamber, and a supply device for supplying (1) a liquid based on polyalkylene glycol miscible with water as the bearing lubricant.

Method for forming an object (2) of thermosetting synthetic material in a mould (6), having at least one chamber (9), according to which method a mixture of components, which react and cure above a critical temperature, is put in liquid form in the chamber (9) through an inlet piece (1), which is provided with at least one filling duct (3,5) which opens into the chamber (9). The mixture is allowed to react and cure by making sure that the temperature of the mould (6) is higher than said critical temperature. The object (2) with the inlet piece (1) is removed from the mould (6). More particularly, the liquid mixture is inserted in the mould (6) through the inlet piece (1) which sticks through a wall (8) in the mould (6) and which extends outside the mould (6), by means of a casting nozzle (14) which is kept at a temperature which is lower than the critical temperature, whereby the extremity of the casting nozzle fits liquid-tight on the filling opening (4) of the above-mentioned inlet piece (1). At least during the filling of the mould (6), the inlet piece (1) has a lower temperature than the above-mentioned critical temperature, such that the curing first takes place against the inner wall of the mould (6) and finally against the inlet piece (1), and during the curing in the mould (6) a pressure is exerted on the curing synthetic via the cashing nozzle (14).

A process for separating sulfur-containing compounds other than mercaptans from gaseous streams. A gaseous stream including mercaptans and other sulfur-containing compounds is brought into contact with a solid supporting material coated with a thin layer of an amine-containing active agent capable of selectively adsorbing the sulfur-containing compounds other than mercaptans. This process permits the monitoring of mercaptans in gaseous streams without interference from other sulfur-containing compounds, as well as the purification of mercaptans.

The invention concerns a process for ultra-drying of a gas or gas mixture by bringing this into contact with a silicate containing material. In order to obtain a residual water level of 5 ppb or less, the invention is characterized in that the gas or gas mixture is brought into contact with a silcate containing material, preferably a zeolite or silicagel, that has been modified with silane, borane, and/or the alkyl and/or halogen substituted compounds thereof. The invention is further concerned with the separation of tritium oxide from gas mixtures preferably with water.

Process for ultradrying of a gas

A porous solid such as a zeolite of clay can be degassed to make it suitable as an adsorbent, after which the entrances of the pores are narrowed to a desired size by treating the porous solid with two chemisorbable materials, one of which is diborane. The treatment may be repeated. The purpose of the first such treatment is to make the pore entrances so narrow, that unduly large molecules cannot enter and the smaller ones can, while a later treatment may serve to narrow the pores still further, so that the adsorbed molecules cannot escape.

Method for a controlled change of the pore size in solids

A clay material of the polygorskite group, pretreated or not, is degassed and contacted with a gas to be adsorbed and after adsorption the clay is heated while in contact with the gas so that the clay structure collapses, encapsulating the adsorbed gas. If desired the entrances of the pores may be narrowed to a desired size by adsorption of diborane before the adsorption of the gas.

Method of encapsulating gases, vapors, complexes and ions in solids

The present invention relates to compounds, elements or ions encapsulated in a zeolite in a stable manner by adsorption, chemisorption or ion exchange, by using a zeolite treated before together with, or after the introduction of the material to be enclosed with a modifying agent selected from the group consisting of silanes, boranes and germanes, which may be substituted by one or more halogen atoms and/or hydrocarbon groups, and after the introduction closing the pores by a further treatment with the modifying agent and/or by an oxidation treatment.
