One or more streams of tobacco in a rod making machine are tested by several density monitoring units one of which employs a source of nuclear radiation and at least one other of which employs a source of optical radiation. The resulting density signals are evaluated and converted into signals which are devoid of the influence of changes of color and/or blend of fibrous material in the stream or s...

A fibre-reinforced composite material, which is particularly suitable for use as metal core in penetrating projectiles, consists of tungsten/heavy metal alloy fibres which are embedded in a matrix of a metal powder, the density of the matrix being equal to or greater than that of the tungsten/heavy metal alloy. The fibres in this case have a structure in which elongate, unidirectionally arranged t...

An adaptor 14 permits the connection of enteral transfer apparatuses, such as a dropping chamber 16, to bottles 10, 12 whose necks 24, 26 have different opening diameters. For this purpose, the adaptor 14 has two caps 20, 22 which are arranged coaxially to one another, have different opening diameters and can each be placed on an associated bottle opening.

A stackable chair has a frame which comprises, in planes running approximately parallel to a plane running perpendicularly through the backrest (24), approximately U-shaped frame sections, the sides (16, 17) of which, i.e. the chair legs, point upwards, while the curve (13) of the U is situated at the bottom. In the front region of at least one such U-shaped frame section, there is provided an ele...

Polyurethane foams are prepared by reacting 1) polyisocyanates with 2) compounds having a molecular weight of 400 to 10,000, containing two hydrogen atoms which are active towards isocyanates and are polymer-modified polyols and/or polyols containing predominantly primary hydroxyl groups, in the presence of 3) water and/or organic blowing agents and 4) catalysts and 5) compounds of the general for...

By means of an operation process acting in the same direction, a sun shade is moved to different height positions without changing its closed position and opened and closed by drive reversal.
