Title: Vertical rolling mill with exchangeable staging - supported on table positioned on frame with upper retractable section to allow staging removal
Inventor: TANAKA TERUAKI
IPC: B21B13/06
Filed: 1977-10-31
Abstract: Vertical rolling mill with an interchangeable staging for the work-rolls includes a frame with a table on which the staging is positioned. There is a retractable section which is removed from one side of the table by means of >=2 adjacent universal couplings under the table and which are joined to a drive element to rotate in opposite directions. There are tensioning or clamping elements on the retractable section. The stand is braced laterally via the clamping elements and the work-rolls each driven by a respective coupling are arranged as a pair(s) forming a single roll pass for the workpiece. To remove the staging from the frame, the drive motor for the couplings are switched off and the clamping elements operated to withdraw lugs on the elements from vertical recesses in the staging. The staging can then be removed by a crane and a new unit substituted. The arrangement avoids the need to provide a mechanism for lateral and vertical movement of the staging during replacement. A compact design for the mill is achieved.

Title: Extruder worm for very wide range of thermoplastics - has core blending from cylindrical into polygonal cross=section
Inventor: GNEUSS DETLEF
IPC: B29C48/505
Filed: 1978-12-18
Abstract: The shortest distance between the outer edge of the propelling spiral and the highest surfaces of the polygonal core of the worm of an extrusion press. is >=2mm and also =6.7% of the external dia. of the worm. The greatest distance between the outer edge of the propelling spiral and the lowest surface of the polygonal core of the worm is >=10% but also =22% of the outer dia. of the worm. The worm acts on the cylinder for the continuous prepn. of thermoplastic masses and consists of an inlet zone and a mixing and delivery zone with a continuous spiral coil. From the inlet zone the cylindrical core of the worm passes through a short transition zone intoa polygonal form. Used to provide an extrusion worm with a geometry which permits it to have the widest possible application for the plasticising of different thermoplastic materials, under conditions ensuring the gentlest treatment of the materials so that interchanging of worms is unnecessary. The advantage of the new worm is that it works without compression and kneads the thermoplastic against the wall of the cylinder.

Title: Double insulating support for aerial cabling - has two insulators on base of bar triangle so that insulator failure is accommodated
Inventor: MUELLER HORST
IPC: H02G7/20
Filed: 1979-03-01
Abstract: The double insulator support for high voltage wiring, 100kV etc, with a triangular frame is designed so that if one insulator breaks the second can provide direct support to the high tension wires. The unit is designed to support either single or double, one above other, wires. The support (12) is symmetrical with the triangle base (13) carrying the insulators (6, 7) and the apex (14) being a plate for the support force (F) and connection of the side arms (2, 3). Under normal conditions the support force is equally displaced down the triangular frame so that the apex plate (14) has a main load line (15) down its centre due to the equal forces (16, 17) up each side arm (2, 3). The relationship between base of the apex plate (14) and base between insulators (13) is 4:1 with the insulator base being the longer. Should one insulator fracture the apex plate pulls the defective unit clear as it takes the load down one arm.
