Title: Flame cutting steel slabs in continuous casting plant - where microprocessor controls burner movement, so flame cannot impinge on rollers carrying the moving slab
Inventor: HENNECKE FRANZ
IPC: B22D11/126
Filed: 1979-07-17
Abstract: Parent patent described the automatic flame cutting of a slab travelling at the casting speed. The novelty is that the transverse travel of the flame cutting burner across the slab is adjusted, so that the flame does not impinge on a roller carrying the slab and forming part of a roller track. If no rollers had to be avoided, the burner would travel along a diagonal path, due to the combination of the transverse travel of the burner with the longitudinal travel of the burner wagon, the latter motion being synchronous with the casting speed. Due, however, to the presence of the rollers, a microprocessor is used to control burner travel, thus precluding damage to the rollers.

Title: HI=FI loudspeaker construction - has cylindrical sliding surface and very fine wires woven into concentric supporting membrane
Inventor: WALLOSCHKE ERNST DR ING
IPC: H04R9/06
Filed: 1979-10-25
Abstract: In place of the semi-soft peripheral suspension ring conventionally holding a loudspeaker membrane, a cylindrical sliding surface (94) is provided on a guide ring (9) against which an accurately beaded portion (5a) of the membrane cone (5) bears. This design eliminates various distortions of the sound characteristics resulting from a semi-soft suspension ring. A further improvement is provided by a method eliminating the adverse effect of the coil lead mass on the moving coil. The method consists in weaving into the concentric supporting membrane (7) a large number of very fine wire strands in a distributed fashion and connecting them at two coil terminals (4a) with the coil (4). The external connection is obtained over soldering lugs (11). Because of the improved cooling over the increased surface, the total copper cross-section and the added mass may be further reduced.

Title: Cooling element for metallurgical furnaces, esp. blast furnaces - using steel tubes coated with aluminium suspended in silicone lacquer, and then embedded in casting
Inventor: WIENEGGE HEINZ
IPC: B22D19/16
Filed: 1980-03-31
Abstract: Steel tubes are cleaned, and are then coated on their external surfaces with a silicone lacquer contg. a fine dispersion of Al powder. The coated tubes are dried, and are placed in a foundry mould, so that a casting can be made in which the tubes are embedded. The properties of the tubes are unaffected, but they have an external coating of Fe(x)Al(y), which is thin, brittle, and has good thermal conductivity. The bores of the steel tubes may be coated with a silicone lacquer, in which case the tubes are pref. cooled during the casting operation. The Fe-Al coating provides good heat transfer between a cast iron element, e.g. a plate, and cooling water circulating through the tubes embedded in the element. The coating prevents the carburisation and embrittlement of the tubes during the casting of the element. The thermal stress created by cooling a furnace produces fissures in the brittle Fe-Al coating to compensation for differences in thermal expansion.

Title: Fluid mass flow measurement - by measuring kinetic energy imparted to electrically driven mechanical oscillator
Inventor: KLEINWAECHTER JOHANN PROF DR I
IPC: G01F1/00
Filed: 1980-08-28
Abstract: A mass flow measurement device is for liquid or gaseous media and measures the energy imparted to a mechanical oscillation system by the medium as it passes through the system. The system performing the mechanical oscillations contains two tubular springs oscillating in anti-phase. The medium passes through the tubes which receive additional kinetic energy from it. The additional kinetic energy is converted into heat in a rotation symmetrical transfer chamber by internal dynamic friction. The conversion takes place without feedback to the torsional oscillator whose amplitude is held constant, for a constant frequency by regulating the drive current. The electrical drive energy is therefore proportional to the mass flow.
