Abstract: ® In contrast with the known method of cleansing surfaces by the projection of sand particles in an air stream against the surface, the present invention proposes to project particles of ice or other frozen liquid at the surface with the result that the spent particles will thereafter melt at the ambient temperature and be readily removed from the site and separated, if necessary, from contaminants dislodged from the surface.Apparatus according to the invention comprises means (2, 3, 5, 13-16, 21) for the introduction of ice particles continuously into a stream of pressurised air (20), preferably mixed with water (19, 20). The means may comprise a plurality of containers (20), each successively passing between a position where they receive ice particles from a supply and a position where they release the particles to the stream.

Abstract: There is proposed a process for the manufacture of wood fiber boards, wherein by far the largest part of the outer layers to be conventionally sanded away no longer consists of wood fibers but of wood dusts of a defined particle size, a material which is available as waste from other consolidations of wood raw materials. By employing the process of the invention, it also is possible to achieve an only small density drop towards the center of the board, so that this process is particularly suitable for the manufacture of medium density wood fiber boards with a weight of 600 to 950 kg/m3.

Abstract: The distance element (4) is intended to preserve the spacing (5) between a fluorescent lamp (3) inserted in light fixtures having tubular lamps and a lamp holder carrier (1.1). Instead of a commercially available lamp holder (2) with a lamp holder body (2.1) and lamp holder foot (2.2), the bridge-shaped distance element (4) is placed onto the plug-through opening (1.11) on the inside of the lamp holder carrier (1.1). In order to preserve the previously determined spacing (5), the glass bulb diameters, which vary depending on the type of fluorescent lamp, are adapted using the dimensioning of the height of the supporting limbs (4.1; 4.2). The edges (4.41; 4.51) of the spring tongues (4.4; 4.5) engage the lamp holder carrier (1.1) from below through the plug-through opening (1.11). When the distance element (4) is mounted, the lamp holder (2) is no longer pushed through the plug-through opening (1.11) but is pushed from the web (4.3) through the plug-through opening of the distance element (4) until the spring elements (2.21) lock. At the same time, the centring cam (2.22) engages in the centring hole (4.32) and centres the lamp holder (2) in the process. <IMAGE>

The error signal (E1) is received by a microprocessor (MP) that generates outputs (A1, A2) converted into analogne from form (A1, A2). These signals are used to provide an offset compensation for the control amplifier (TR) that differentiates the outputs of the stacking detectors to generate the tracking error (TE).
