Inventor: VERKASALO MATTI
IPC: D21G1/02
Filed: 1985-04-01
Abstract: The invention relates to a method for controlling the temperature level and/or the temperature profile along the axial direction of the shell of a roll used in paper manufacture. In the method, heat transfer fluid is used from which a layer of suitable thickness is generated on the inner surface of the roll shell by the influence of the centrifugal forces generated by rotation. The layer of heat transfer fluid is divided into mutually separate annular segments, and elements acting upon the temperature of the fluid layer are fitted in each of the segments. In addition, a roll used in paper manufacture, in particular a heatable calender roll, is described which consists of a cylindrical shell rotatably mounted at its end faces. In connection with the method, for dividing the fluid layer into individual segments, there are, inside the roll shell, annular partitions which divide the inner surface of the roll shell in the axial direction thereof into individual segments. In each of the segments, elements are arranged which exert an influence on the temperature of the fluid layer.

Title: Venting device for centrifugal pumps
IPC: F04D9/04
Filed: 1985-04-12
Abstract: In a venting device for a centrifugal pump, which can be used as a fire pump and in the initial state is not self-priming, the venting pump provided is a fluid-ring pump which is operated with an antifreeze as a working fluid. Provided in the venting flow path leading from the intake chamber of the centrifugal pump to the inlet of the venting pump there is a float valve which blocks this venting flow path as soon as a sufficient amount of flow medium penetrates into the housing of the float valve. The working fluid of the venting pump which is entrained by the gas stream expelled thereby is condensed by means of a separator and, in a closed circuit, is returned to the inlet of the venting pump. The section of the vent line leading from the float valve to the inlet of the venting pump is automatically ventilated by means of a flutter valve if, after the venting pump has been switched off, the pressure in this line section has risen again to a minimum value of from 0.7 to 0.8 bar.

Title: Gearing for changing the direction of rotation of two output shafts, especially for twin-screw extruders
Inventor: MADER LEO DIPL ING
IPC: B30B11/24
Filed: 1985-10-04
Abstract: The invention is employed for driving the screws of twin-screw extruders for plastics processing in the same or in opposite directions. The aim of the invention, to reduce the manufacturing outlay for and costs of a gearing of the above type, gives rise to the object of creating a gearing of kinematically simple construction with a small number of gearing elements. The solution according to the invention envisages arranging three shafts with three gears in the form of an equilateral triangle in a gear case. All the gears have the same number of teeth and the same module. Two of the gears are of identical design. An addendum modification deviating from zero ensures that there are only two tooth engagements between the gears. The gear case can be mounted by means of the shaft stubs on two shafts of a reduction gear unit and arranged so as to be relocatable by an angle of 120 DEG  to perform the change in the direction of rotation of the output shafts. <IMAGE>

Patent DE-3600144-A1 (DE)
Inventor: BALD WILFRIED
IPC: B21B45/06
Filed: 1986-01-07
Abstract: An apparatus is provided for removing scale from a hot rolled steel strip by rolls acting by grinding and/or milling so that these rolls are uniformly effective in all regions of the steel strip and an appropriate uniform removal of the scale layer occurs. This is attained when driven grinding rolls adjustable toward the surfaces of the steel strip are provided of which at least two opposing rolls are axially slidable in opposite directions and have inversely oriented S-shape contours. These contours complement each other completely flawlessly in one definite position of the grinding rolls. In one such position the rolls provide a uniform engagement on both sides of a steel strip with a nearly rectangular profile. In fact the rolls by appropriate axial sliding and application of bending forces if necessary may be adjusted to fit the actual profile of the steel strip so that a uniform engagement on the scale layer is guaranteed and a locally excessive grinding and/or milling in the central region of the steel strip is avoided.
Patent DE-3605782-A1 (DE)
Title: Swimming-pool covering
Inventor: KRUELL ANDREAS
IPC: E04H4/08
Filed: 1986-02-22
Abstract: For swimming pools, use is made of coverings which exhibit a carrying layer and an insulating layer connected thereto. Preferably, use is made of air-chamber sheets, in the case of which the air chambers are arranged with respect to one another such that continuous grooves or longitudinal slots are obtained at least in one direction. The covering is guided onto the water surface with the carrying layer directed towards the shaft and between the pool edge and the shaft. The shaft is assigned a parallel water tube which is arranged at a distance therefrom and has nozzles distributed over it, via which water is sprayed continuously onto the insulating layer exhibiting the air chambers or the longitudinal slots or grooves. Consequently, the unwinding of the covering is facilitated, winding up is improved, owing to close abutment of the individual layers, and automatic cleaning of the underside of the covering is achieved. By means of a hollow tube, which is assigned to the transverse end bar connected to the sheet in an offset manner, and a bracing tube assigned to the shaft, it is possible to brace the entire covering on the two opposite pool edges in an effective manner, with the result that the covering also serves at the same time as a safety covering. <IMAGE>

Patent DE-3610777-A1 (DE)
Title: Car body
Inventor: BIEBERICH WALTER
IPC: B60R9/02
Filed: 1986-03-29
Abstract: The invention relates to the body of a car with bumpers, at least one of which is extended, together with a skirting-like edging part which is arranged below, around the body corners and laterally until it reaches the adjacent wheel openings. Continuing the bumper, together with the edging parts below it, until they reach the wheel openings is advantageous from the point of view of aesthetic appearance, safety and streamlining. Apart from this, there is a demand for modern cars to have additional storage space which is accessible at any time even when the vehicle is fully loaded, without unloading being necessary. It is therefore proposed according to the invention that at least one extension, which extends to the wheel opening of the bumper and of the edging part, take the form of an additional storage space with lids which can be opened laterally, i.e. to use the inherently dead space behind and/or in front of the wheel opening as storage space which is accessible from outside.
