Dimensionally stable, cured phenolic foams are described that have a thermal conductivity after 10-days below 0.0185 watts/m DEG C, a density of 30 to 70 k/cubic meter and a closed-cell content of at least 85%.

Partially cured phenolic foams having a cell structure that is resistant to rupture under pressure and a slow deterioration of thermal insulation value are described. These foams can be cured to achieve dimensional stability without substantial adverse affect on their structure.

An erodible sonde for detecting sand in the gas conveyed through a pipe. Such a sonde is constituted by a thin aluminium tube, one end of which communicates with a device for measuring the pressure outside the pipe and the other end of which is closed, the inner wall of this tube being in contact with a discontinuous prop or support means such as a steel spring with contiguous coils. Such a device...

The S-cam is carried by a brake shaft 12 (e.g. operated by a spring- loaded cylinder through a rod linkage) and is forced by a spring 1 against a fixed brake carrier 8 to damp out vibrations, which occur when braking, irrespective of the direction of the wheel rotation. As shown a compression spring 1 with hardened faces 9, 10 is provided between a sleeve 2 and an abutment ring 3 to force the brak...

In apparatus for conditioning crops such as grass, two rotors (12, 37) are positioned opposite each other on opposed sides of a passage (14) and engage crop passing through the passage and condition the crop by cooperation between the two rotors (12, 37). Preferably each rotor (12, 37) is a brush having a multiplicity of stiff, resilient, elongate elements (10) which are yieldable in more than one...

A substance to be treated is brought into a treatment column (10) and kept in suspension (11) in the latter by the injection (A) of a fluidizing gas into the bottom part of the column. According to the invention, a plasma is injected (D) into the column in at least one direction within a radial plane relative to the column. Preferably, the plasma is produced by high-frequency induction and injecte...

The invention relates to a method of regulating the tar content of precooked anodes intended for the production of aluminum by electrolysis, to an optimum level Bm corresponding to the maximum dry density of the anodes, which utilizes measurements on crude anodes emerging from compaction and without awaiting the results of the cooking process. The method comprises the following repeatedly carrying...

A porous ceramic body of high structural strength and integrity is disclosed, along with the method of fabricating such, whereby a curable resin and a sinterable ceramic are mixed and then admixed to removable pore formers, then consolidated into a green body, the pore formers removed, and sintered into the porous ceramic body.

A fireguard plate contains from 10 % to 14 % by volume of an organic binder, from 40 % to 60 % by volume of hollow inorganic microstructures and from 26 % to 50 % by volume of aluminium hydroxide. The fireguard wall is manufactured by adhesive bonding or by cemented bonding of such plates.

A user connected by telephone to a central telephone exchange can inform an automatic switching communications device directly of his own telephone number by dialing on his telephone set, which determines the corresponding address and all other possible characteristics from an on-line directory. The available taxis are entered in a stand-by memory. The taxis in first place in the stand-by memory i...
