Title: Construction plate for e.g. paving slabs - composed of concrete as a carrier material with an additive of recycled material
Inventor: HERBERGER HANS
IPC: C04B14/22
Filed: 1990-10-11
Abstract: Building plate is composed of concrete as the carrier material with an additive (4) as a bulking material and/or surface layer (5) of the plate, etc., using recovered and recycled material. The additive is pref. embedded in the carrier material and/or cement in a keyed bond. The additive can be ground glass, previously sorted by colour and/or size, or ground sorted plastics can be used.

Patent DE-4107617-A1 (DE)
Title: Fibre union material with hollow fibres embedded in matrix - has fibres, sealed at ends, filled with gas or fluid which are heatable by heating wires inserted in them in matrix or by external source
Inventor: ZIMMERMANN WERNER DIPL PHYS
IPC: C08J9/32
Filed: 1991-03-09
Abstract: The fibres are filled with a gas or fluid prior to be placed in the matrix, and sealed at their ends. By heating, either inductively with heating wires in the hollow fibres or in the matrix, or from an external source e.g, with hot air, the increase in temp. results in a rise in inner pressure in the fibres, whereby the inner pressure is in equilibrium with the mechanical tensions in the fibre walls. As the result of vol. expansion of the gas or fluid in the fibres, i.e, with a fibre 100cms long a length alteration of approx. 1mm occurs at a temp. rise of 1 deg. C., on account of the high elasticity module of the fibre high tensions occur. This in turn leads to the formation of a suitable matrix material with fibres in which there is increased rigidity. ADVANTAGE - A fibre union matrix which is cheap to produce, and has variable strength properties.

The cone plate is pref. made of sintered steel. USE/ADVANTAGE - Cone clutch with internal and external friction faces. Since the sleeve faces lie in the cylinder faces, the radial width of the window in the connecting part can be small so that the connecting part stays dimensionally rigid.

IPC: B23K26/142
Filed: 1992-02-01
Abstract: The material removal from a moving workpiece comprises using a high-energy pulsed and focussed laser beam. The beam is synchronised to cover a predetermined region of the workpiece. At the same time, deviations of a physical amt. from its target value are evaluated in real time, and the beam is applied in successive steps until the actual value is within a given tolerance range.

Then a number of pulses are determined and applied with supply of a cleaning gas. The laser (1) includes a device (16) for time and/or space variation of the pulse energy density distribution. Pref. beam and motion control systems (8, 25) synchronise application of the beam (22) to a region (21) of a rotating workpiece (20). The focus spot of the laser beam is pref. moved along the axis of rotation of the workpiece so that material is removed from a predetermined area. The cleaning gas is an inert gas. Both gases are applied in a direction essentially parallel to the beam axis, with a pressure of 2-10 bar. The device (16) is an electro-optical or acousto-optical modulator or a Kerr cell. The laser (1) is a solid-state Nd laser or a CO2 gas laser. USE/ADVANTAGE - Used for automatic balancing of small fast rotating elements of gyroscopes, dentistry appts. etc..
