Patent DE-2856733-A1 (DE)
Inventor: SCHUEGRAF EBERHARD DIPL ING
IPC: H01P1/02
Filed: 1978-12-29
Abstract: A rectangular wave guide H-elbow bent across the narrow side of the wave guide and having its outer corner flattened by a symmetrically angled conducting plane. The present invention provides for the reduction of the reflection factor in such elbow by providing that the relative corner flattening of the wave guide produces a value of xH/a greater than 0.73 wherein a is the length of the wide side of the wave guide and xH is the distance from the apex of the wave guide before it is flattened by the conducting plane to the junction of the conducting plane with the narrow side of the wave guide. Furthermore, capacitive loading means of cylindrical form are arranged in the area of the geometrical median w of the bend of the wave guide and being in the form of conductive cylinders 1 or 3 as illustrated in FIGS. 2 and 3.

Title: Bending machine for mfg. gutters or tubes from metal sheet - esp. roof gutters from metal sheet coated with plastic, which is not damaged by bending rolls
Inventor: DANGEL GOTTLIEB
IPC: B21D5/14
Filed: 1979-02-02
Abstract: The machine contains a set of >=3 long parallel bending rolls, which extend over the entire length of the metal sheet being bent; and some of the rolls are driven.

Title: Moist foundry moulding sand reclamation - in which hot moulds are fed into chamber using controlled vacuum to remove water as steam which is condensed and reused
Inventor: MUSSCHOOT ALBERT
IPC: B22C5/13
Filed: 1979-06-05
Abstract: The mould contains a metal casting, and both are >93 degrees C, due to the casting process, when they re placed in a vacuum chamber. A vacuum of >0.207 bars is applied to chamber, thus causing the evapn. of the moisture in the sand. The resulting steam is removed from the chamber and the vacuum is switched off. The mould and casting are pref. at 93-316 degrees C when placed in the chamber, and the pressure in the chamber is then reduced to 0.069-0.207 bars. In the pref. plant, trolleys carry the moulds successively underneath the chamber, from which the steam and dust are carried to a condensn. chamber where they are collected and re-used. Water and fine dust can be removed from the hot moulds without the risk of an explosion.
