Patent NO-164359-C (NO)
Inventor: LAUREN HENNING JOHN EMIL
IPC: D04H1/74
Filed: 1987-12-21
Abstract: PCT No. PCT/FI87/00054 Sec. 371 Date Oct. 20, 1988 Sec. 102(e) Date Oct. 20, 1988 PCT Filed Apr. 24, 1987 PCT Pub. No. WO87/06631 PCT Pub. Date Nov. 5, 1987.The invention relates to a method and a device for producing a mineral wool web from a thin primary web formed on a movable collecting surface (6). According to prior known methods, the primary web is folded on a receiving conveyor (18) in an overlapping configuration so that the desired thickness of web is achieved. It is also known to combine two or several primary webs and to form the final mineral wool web by folding. The problem when producing mineral wool webs is the high rate of production of the primary webs and consequently, the high requirements on the devices in the further process and a great loss of material because of uneven edges which have to be cut down. According to the invention, the primary web is split into separate sheets before the deposit on the receiving conveyor (18), and the sheets are deposited by an oscillating distributing conveyor (16) in an overlapping configuration on the receiving conveyor, or, in case sheets are being produced, stacked on top of each other. The method offers several possibilities of reducing the feeding rate of the sheets and thus facilitating the deposit on the receiving conveyor. The flow of split sheets may for instance be separated (11, 12) into two or several flows to an intermediate conveyor each (14, 15) and the sheets may be stacked before the deposit. The cutting of the primary web may be performed on the collecting surface (6) or optionally after this on an intermediate conveyor.

Abstract: The invention relates to a device for separating liquids and/or solids from a high-pressure gas stream, comprising a cylindrical vessel with a virtually vertically set axis fitted with:  a top compartment to which the gas stream is fed; a middle compartment comprising a number of blades set helicoidally around the axis; a bottom compartment for separating the gas and the liquid and/or solids and a coaxial gas discharge pipe projecting upward from the bottom compartment through the middle and the top compartments, around which helicoidal blades have been fixed, each helicoidal blade being composed of a bottom section with a constant pitch and a section with a pitch gradually increasing in upward direction. The constant pitch of the blades lies between 5 and 20 &loz& , preferably between 10 and 15 &loz&  and increases in upward direction to at most 60 &loz& , preferably 45 &loz& . Between the helicoidal blades are vertical baffles which, viewed in the flow direction of the gas, extend from the discharge pipe in the direction of the inner wall of the vessel. These baffles are shaped like flat planes with sharp free ends. Conical sleeve sections are provided in the separation section of the device, at the outer wall of the gas discharge pipe, the angle between the sleeve sections and the centre line of the vessel being between 15 and 45 &loz& . The distance between the free end of the sleeve sections and the inner wall of the vessel is between 0.25 and 0.70 and by preference between 0.3 and 0.6 of the distance between the outer wall of the gas discharge pipe and the inner wall of the cylindrical vessel.

Granted: 1997-08-12
Abstract: An expandable mine bolt assembly having a shell and wedge unit threaded upon the shank of an elongated bolt.  The shell contains at least one or more leaf sections.  The arms of a U-shaped metal strap are joined to the shell and the strap is arranged to pass over the wedge and the distal end of the bolt.          At least one arm of the strap is provided with a wrapped section containing folded legs.

Abstract: A protector for bore rods and pump rods that is frictionally connected to the rods comprises an elastomeric body with a metal reinforcement.  The elastomeric body comprises a middle section and end pieces whereby the end pieces have a diameter that is reduced relative to a diameter of the middle section.   Metal sleeves enclose the end pieces  for  receiving  radially  acting  forces resulting from heat expansion of the elastomeric body during operation.  The length of the metal sleeves  is  preferably greater  than  the  inner diameter of the metal sleeves.   The end pieces that  are  enclosed  by  the  metal  sleeves  are radially pre-loaded with respect to the metal sleeves  at  ambient  temperature.    The  radial thickness of the wall of the end pieces and the length of the metal sleeves are selected such that at  elevated  temperatures  during  operation  the pressure exerted by the protector onto the bore rods respectively pump rods is greater than at ambient temperature so that the heat expansion improves the frictional connection between the protector and the respective rods.
