Title: Demolition arm
Inventor: LEWIN HEINZ ULRICH
IPC: E04G23/08
Filed: 1993-03-25
Abstract: Provided for demolition work is an apparatus which can be articulated on an excavator or on the jib thereof, said demolition arm, in the retracted state, having a length of 15.0 m and, in the extended state, having a length of 29.0 m. Other dimensions are also conceivable. This large degree of displacement is made possible in that the demolition arm is designed as a hollow tube and comprises a plurality of part-arms which can be nested one inside the other. Said part-arms receive a reverse-attached operating cylinder which is connected to the central arm by means of the cylinder housing and, consequently, may also be used as a multiple telescopic cylinder. Supply with hydraulic fluid takes place via the piston-rod eyelet. The substantially increased extension length and the resulting greater reach and sufficient stability characterise the demolition arm according to the inveniton. <IMAGE>

Title: Device and method for electrolytic deposition of paint present in water washed out from spray booths
Inventor: BEREWINKEL KLAUS DIPL ING
IPC: B01D57/02
Filed: 1993-06-22
Abstract: The invention relates to a device and a method for electrolytic deposition of paint present in water washed out from a spray booth. The device has a revolving deposition electrode which is immersed in the wash water, and an opposite electrode of opposite polarity which is likewise immersed in the wash water and is at a distance from the deposition electrode, as well as a scraper for removing from the deposition electrode the paint deposited on the deposition electrode as a paint coat. In order, with such a device, also to make it possible to clean economically wash water with low paint concentrations, the opposite electrode is guided, in the region of the immersed deposition electrode, approximately concentrically about said deposition electrode and forms with it a flushing gap which can be exposed continuously to fresh, i.e. not yet treated, wash water.

Title: Filter device for cleaning liquids
Inventor: LINZMAIER GUENTER
IPC: B01D29/23
Filed: 1993-05-17
Abstract: The object of the invention is to improve a device of the type characterized at the beginning to the effect that waste water can be readily filtered quickly and predictably and after short and thorough cleaning the sludge is concentrated and the filtering operation starts again. This object is achieved according to the invention in that the liquid, upon contamination, is driven automatically by the displacement principle and the applied liquid pressure into the closed screen housing 1 with interlocking screen anchor 2 according to the contamination of the waste water and is automatically cleaned without external drive or sensor at optimum filter life. The filter cake obtained in the process is in addition thickened on account of the time so that thick matter is formed during the filtering operation. The thick matter is forced out of the device automatically at maximum filling by means of a sludge pump. <IMAGE>

Patent DE-4340132-A1 (DE)
Title: Conveyor band with screwed-on cleats
Inventor: FARWICK BERNHARD
IPC: B65G15/42
Filed: 1993-11-25
Abstract: In conveyor bands with cleats which are designed as drivers for the conveyed material and which are connected to the belt or band material via screws, nuts for the screw connection being worked firmly into the cleat, the invention proposes that the nuts of a cleat be fastened to a common carrier rail which is worked firmly into the cleat. This on the one hand allows rotation even around deflecting rollers having a small diameter and on the other hand permits a higher load-bearing capacity of the cleat, since loads occurring at particular points do not have to be absorbed solely by the next adjacent screw connection.

Title: Recycling plastics waste for highway and earthworks construction
IPC: E01C3/00
Filed: 1993-12-21
Abstract: Plastics waste material is converted into a material for use in highway construction and earthworks, by adding minerals. After the plastics mass has been softened, the minerals are mixed through as fillers, sand or splinters, and reduced to loose materials with the required cubic granular size, to be shaped, broken or cut. The mineral dust is extracted and/or an adhesive coating is applied through heating or pretreatment, using bitumen, synthetic resin or another bonding agent while the mass is still plastic, giving a covering on all sides or over part of the surfaces. The material is then reduced to the required grain size by breaking or cutting.
