Patent DE-2365363-A1 (DE)
Title: Continuous 'V' belt vulcanisation with applied pressure - produced by discs of varying diameter at different runs of belt
Inventor: MUELLER ALEXANDER
IPC: B29D29/10
Filed: 1973-07-25
Abstract: A continuous post-vulcanisation treatment appts. for V-belts comprises a stretching zone, in which the hot belt is loaded by pressure-applying members. Each of these members consists of a freely-revolving conical portion and, adjacent to it, a freely-revolving cylindrical portion. The conical portion is made up of a stack of independently revolving discs of different diameters. Pref. the thickeness of each disc is  the gap between adjacent belts. Each complete pressure-applying member may be mounted on a pivoting arm, with a spindle adjustment to vary the length of belt. Thus the uniform heat treatment gives high length stability.

Title: Rainwater gully for flat roofs - has sealed flexible joint between gully inlet and outlet
Inventor: BIENIEK EDUARD
IPC: E04D13/04
Filed: 1974-01-16
Abstract: The roof gully is intended for draining rainwater from flat roofs into a sewerage system and it can be used for connecting to horizontal or vertical drainage pipes or to draining pipes inclined at any angle between these extreme positions. The gully system has an inlet section on which is mounted the inlet channel, a sieve, and a gravel screen. The water flows through the flexible joint and internal flap valves into the outlet channel. The outlet section swivels about the ball and socket joint which also houses a flexible sealing ring. The outlet section houses a double flap valve which is kept closed by permanent magnets. This valve blocks smells and prevents access of cold air into the drainage system to prevent freezing.

Title: Suction draft sinter process with preheating of charge - esp. for iron ore reduction
Inventor: WENZEL WERNER PROF DR ING
IPC: C22B1/20
Filed: 1974-03-28
Abstract: Iron ores are sintered by the suction draft method in which a fuel containing sinter layer is permeated by combustion gas. Before ignition of the sinter layer it is subjected either by blowing or by suction to a hot gas, partic. of reducing character, to preheat the sinter charge to a temp. above which reduction of the iron oxide takes place and ignition is inhibited by controlling the composition of the gas w.r.t. oxidising components (CO, H2O and O2) and/or the temp. of the gas or sinter layer. Also, the proportion of fuel in the sinter mixture is reduced in dependence on the degree of preheating. Also used for sintering cements and other ores. Fuel consumption can be reduced and pollution by SO3 and NOx is reduced.

Title: Accurate power control in spot welding - using electronic control circuit to compensate for differences in electrode contact resistance
Inventor: DRECHSLER GUIDO
IPC: B23K11/25
Filed: 1974-07-30
Abstract: Process is for controlling spot welding machines w.r.t. both time and power output. An optimum build-up curve (the desired curve) is obtd. using a battery to charge a capacitor (I), the voltage across (I) being used as a measure of the power desired; simultaneously, the actual power used is monitored electronically and fed to a second capacitor (II); the voltages on (I) and (II) are compared in a differential amplifier which emits a corresp. voltage driving a controllable resistance, pref. a power transistor, which then controls the phase of the welding machine so the voltage on the capacitor providing the spot welding power matches that on the optimum build-up curve at any moment, and a Schmitt trigger helps to cut off the power when the zero pause on the 50 Hz A.C. mains supply is reached. Irrespective of the large differences which occur in the resistance of the junctions between the welding electrodes and the workpieces, a prescribed amt. of power is delivered.

Title: Wind power driven generators - in which several direct driven units are electrically connected together have gearless connection between wind vanes and generators
Inventor: SPASSOFF GEORGI
IPC: H02N1/06
Filed: 1975-07-29
Abstract: In order to use wind power for industrial as opposed to private purposes it is proposed that a number of generators are grouped together and connected electrically either in series or parallel. The vanes of the wind motor are pref. coupled directly, that is without an intermediate gear train, to the shaft of a d.c. machine. Shaft speed is then not a limiting factor when operating in groups. The output may be used directly in a d.c. distribution system or it may be fed through an inverter into an a.c. network. the elimination of gears allows more efficient operation since there is less mechanical loss, also the structure and assembly are simpler and smaller.
