Abstract: Unit with at least one plate made of a material, which material is permeable to thermal radiation, such as glass ceramic, glass, ceramic or a similar material, as a surface for cooking, frying and/or keeping warm. The unit with at least one plate is on a frame construction with different types of adjustable heat sources distributed underneath and on the plate. Some of the heat sources are distributed under the plate in the form of radiant burners and act indirectly by radiation through the plate. Other heat sources are located above the level of the plate in the form of open atmospheric or atmospheric pressure gas burners and transmit heat directly by producing open flames. The respective heat sources correspond to the cooking, frying and/or warming positions.

Abstract: A hydraulically damping elastic bearing including an inner tube, an outer tube that is placed concentrically or eccentrically apart from the inner tube, and a rubber part inserted in between the inner tube and the outer tube. In the rubber part at least one chamber, filled with damping agents, is placed. Within the chamber at least one elastic end stop body is provided, which end stop body is, if necessary, surrounded with an element that has a greater strength than the end stop body.

Abstract: A ship which has supporting columns which run vertically and are located in the hull of the ship, as well as at least one flat, rectangular area element which extends horizontally and is supported on at least one of these support columns, in which the supporting columns are located at some distance from the corner points of the rectangular area element.

Abstract: A mobile platform in an underground mine supports an electric motor that operates a compressor to supply air under pressure to one or more hoppers containing abrasive particles which are held in suspension and pressurized within the hopper. The electric motor is drivingly connected to a hydraulic pump that supplies water under pressure in a range of 3000 to 4000 p.s.i. through a conduit to the water inlet of a nozzle assembly. A second conduit conveys the pressurized abrasive particles to the nozzle assembly for admixture with the water. The flow of abrasive particles is maintained by the compressed air at a constant flow rate to enhance the output velocity of the water encapsulated particles from the nozzle assembly. The abrasive stream impinges on the surface of a gas well casing to sever the casing as the nozzle assembly is rotated around the casing. In this manner a pipe or gas well casing obstructing a mining operation is removed without generating sparks in the hazardous mine atmosphere.
