Patent DE-3020529-A1 (DE)
Title: Three-stage inert welding gas control - by diaphragm pressure reducer, flow-meter and needle restrictor valve
Inventor: FROEHLICH HANS
IPC: G01F1/24
Filed: 1980-05-30
Abstract: The gas flow rate in inert-gas welding and cutting systems is controlled in three stages. A diaphragm-type of pressure reducing valve keeps a constant reduced pressure independent of external factors in the first stage. The second stage is a flowmeter based on this pressure. In the third stage, a needle restrictor valve passes, when fully open, a flow rate, proportional to a calibration factor depending on the type of gas. Such a control system indicates the true gas flow rate in spite of greatly varying welding conditions. The more reliable flow rate achieved thereby ensures more stable conditions, a better welding quality and saves gas.

According to the invention, this series resistance is reduced in that the base of the depression is formed by the semiconductor layer or its boundary surface adjacent to the monocrystalline layer, and in that at least one electrically conductive contact is provided at least on the base.
Patent DE-3104611-A1 (DE)
Title: Head or insert for chimneys
Inventor: FETTE DIETRICH
IPC: F23L17/02
Filed: 1981-02-10
Abstract: These have a closed frame or ring, in which a multiplicity of elongate metal sheets are mounted pivotably at their lower end. In the position of rest, these metal sheets form a hollow cylinder; the metal sheets can progressively be pivoted inwards out of this position, covering one another in a shingle-like manner, to form a hollow cone, so that the clear passage orifice for the chimney can thus be adjusted continuously. The smoke-gas outflow speed can consequently be adapted to the different loads on the chimney or on the associated boiler system, this being very important particularly where small loads are concerned. The adjustment of the metal sheets to form a more or less acute truncated cone can take place automatically in dependence on the load state.

Patent DE-3110933-A1 (DE)
Title: Agricultural ground-working machine
Inventor: FLECK ALFONS
IPC: A01B33/16
Filed: 1981-03-20
Abstract: In an agricultural ground-working machine (1), there are provided as ground-working implements drivable about vertically directed shafts one or more mulching implements (4, 5) drive-connected rigidly to one another and tilling implements (6, 7 and 8, 9) which are arranged on one side or on both sides of these and overlap their working range (A) on the outside and which are respectively drive-connected to the adjacent mulching implement (4 or 5) via an elastic or rigid drive means (27, 28; 31, 32). In this way, two types of machine are combined with one another and supplement one another. Thus, in one operation, mulching can be carried out in the middle and, at the same time, tilling can be carried out alongside, without separate appliances being required. The width of the mulched region can be adjusted easily, since the tilling implements (6, 7 and 8, 9) are mounted in pivoting arms (10, 12), and there is also a straight separation between the different working regions. <IMAGE>

Title: Method to permit the combustion of a flowable fuel which is composed of particles with different masses
Inventor: LINDE ROBERT VON DIPL ING
IPC: F23C99/00
Filed: 1981-03-31
Abstract: A method is proposed to permit the combustion of a flowable fuel which is composed of particles with different masses, especially coal dust, in the case of which total combustion of the particles is achieved independently of their masses by guiding the fuel and the combustion air towards one another in opposite directions, so that the particles are retarded and diverted by the stream of air. This causes particles with small masses to be burned in the flame immediately, whereas particles with larger masses pass through the flame, in which process they are ignited, after which the stream of air retards and diverts them, and transports them into the flame a second time, where they are then burnt up completely.
Patent DE-3115153-A1 (DE)
Title: Overvoltage suppressor
Inventor: HERRMANN HELMUT ING GRAD
IPC: H01T4/20
Filed: 1981-04-15

Patent DE-3125135-A1 (DE)
Title: Conference circuit
Inventor: GROBEL DIETER DIPL ING
IPC: H04M3/56
Filed: 1981-06-26
Abstract: The time division multiplex connection comprises a connection line which interconnects a number of subscriber stations. The information transmitted from each subscriber station is transmitted in a specific time slot of consecutive pulse frames in time division multiplexing. To set up a conference circuit, the associated subscriber stations in each case contain a plurality of registers in which the information in each case of one time slot of the pulse frame is stored so that the subscriber station can receive the information from a plurality of time slots of a pulse frame and can thus receive a plurality of transmitting subscriber stations. The registers are thus connected via a demultiplexer to the time division multiplex link. A decoder which restores the original analog signal is connected to each register. The outputs of the decoders are connected via a switching arrangement to the reproduction device so that the information of selectable time slots and therefore selectable subscriber stations can be connected, if necessary also in multiple fashion for emphasis, to the reproduction device(s). The demultiplexer and switching arrangement can be controlled on a centralised, decentralised or combined basis. <IMAGE>

Patent DE-3133357-A1 (DE)
Title: Process for continuous catalytic fluidised-bed cracking of crude oil feedstock
Inventor: PRATT ROY EARL
IPC: C10G11/18
Filed: 1981-08-22
Abstract: The temperature of the dense phase of the fluidised catalyst bed in the regeneration zone of an FCC plant is controlled by adjusting the level of the fluidised catalyst bed above the riser outlet in the reaction vessel. As a result, the coke deposition on the catalyst in the reactor and hence the quantity of heat released in the regeneration zone on combustion of this coke is influenced. Furthermore, the rate of the oxygen-containing regeneration gas fed to the regeneration zone is adjusted such that sufficient oxygen is present to obtain substantially complete combustion of the coke to carbon dioxide. The oxygen content of the exit gas is held in this way at a desired level within a range of about 1-10 mol % and an exit gas having a carbon monoxide content of 0-500 ppm is thus generated. The residence time of the catalyst in the dense phase of the fluidised catalyst bed of the regeneration zone is adjusted such that a regenerated catalyst having a very low content of carbon residues is obtained.
