Title: Light concrete for road construction - contains sintered polystyrene foam particles to reduce surface smoothness and the formation of surface ice
Inventor: KADEN LOTHAR DIPL ING
IPC: E01C11/26
Filed: 1993-01-11
Abstract: To produce a light concrete with low thermal conductivity, a polystyrene foam and especially waste polystyrene foam is broken down into particles or foamed. The foam particles are sintered through rapid heating, and then mixed with a cement and water mixture which is then allowed to set. The sintered polystyrene foam particles are encapsulated in a thin mixture of cement and water and, on site, are mixed as a dry material with the cement in a free drop mixing action, and then allowed to set. USE/ADVANTAGE - The material is for the reduction of surface smoothness or the development of ice on road surfaces at crossings and junctions and over bridges. The material gives a good thermal insulation action and, as it is permeable to water, it does not hold water which can freeze into ice on the road surface.

Patent DE-4311364-A1 (DE)
Title: Rolling tools with asymmetrical pitch and profiles adapted to the forming process
Inventor: KUERTEN KONRAD
IPC: B21H5/02
Filed: 1993-04-06
Abstract: During profile rolling on cold-rolling machines with rotating tools, the workpiece is, in the case of conventional rolling tools, initially rolled by means of tip circle pitch, and the root circle pitch of the workpiece is produced using the tip circle pitch of the tool by means of the deformation process. As a result, the material at the workpiece is distorted and this leads to damage to the material and to inaccuracies. In order to keep the deformation of the material extremely small in forming processes on cold-rolling machines and thereby prevent fracture of the material due to overworking, the rolling tool has been produced with an asymmetrical pitch and the profiles adapted to the deformation process. It is ensured that the forming process is adapted to the material and that distortion of the material does not occur. Uniform and higher accuracy of the toothing is likewise achieved since the material is provided with the correct pitch and shape during the initial rolling process by virtue of the differing profiles and asymmetrical pitches.   Possible applications in the production of encircling profiles:     - knurling DIN 82   - serrations DIN 5481 - special profiles. -

Furthermore, the sealing strips are mounted on the outer sides of the external cage and opposite on the walls of the housing. The sealing strips consist of moulded strips and elastic profile seals inserted therebetween, or of interlocking strips which form a labyrinth packing (seal, gland).

Title: Hydraulic cylinder with end-position brake valve
Inventor: FUNKE SIEGFRIED
IPC: F15B15/22
Filed: 1993-05-04
Abstract: Hydraulic cylinders working according to the plunger principle exhibit a load-dependent behaviour in their lowering phase. A hydraulic cylinder with an end-position brake valve is therefore proposed. The brake valve works independently of load to the greatest possible extent and in its braking profile can be embodied to suit the requirements. This object is achieved by the damping piston having all functional elements of a two-way flow-limiting valve and devices for alternatively influencing the controlled oil flow. Hydraulic cylinders of this type are used in mobile hydraulic cylinders, in particular in fork-lift trucks. <IMAGE>
