Patent DE-2431903-A1 (DE)
Title: Extruded flexible aluminium waveguide - has symmetrical internal cross section with thinnest wall regions at centre of broad face to allow bending
IPC: H01B11/18
Filed: 1974-07-03
Abstract: The extruded pliable alumium waveguide has its internal cross section symmetrical about its shorter and longer axes, but with its wall thickness thinner at the centres of its broader faces i.e. at the ends of the shoter cross-sectional axis. The cross section may be elliptical or rectangular or somewhere between the two. This thin region of wall thickness may bow inwards into the waveguide cavity to a greater or less extent, e.g. it may bow sufficiently for the waveguide section to resemble a dumbell. The waveguide can be bent without significantly altering its electrical properties, i.e. without forming detrimental 'corners'.

Title: Mine local ventilation flexible ducting - coaxial lengths pulled out starting from outer most length ends located
Inventor: HOFFMANN DIETER
IPC: E21F1/04
Filed: 1974-07-10
Abstract: Local mine ventilation flexible ducting extends by means of a number of coaxially stored lengths connected to each other at the ends to permit their being drawn out to form ducting of the desired length. It is always the outermost length (9) which is drawn off those inside (7, 3), the outward ends (6) of these inside lengths being anchored until the length immediately above them has been fully removed. The ducting is preferably made by folding back the outer layers progressively, with reinforcement (20) provided on the outward end (6) of each of the layers lying inside an outer length (9). The reinforcement should take the form of strips (20) located in pockets (21) which are open in the pull-out or drawing-off sense.

Title: Resistance welding machine, esp. for chain links - where sec. conductors can move in two directions w.r.t. the transformer core
Inventor: DITGES GUENTER DIPL ING
IPC: B23K11/00
Filed: 1974-08-14
Abstract: Electric resistance welding machine for bar-shaped profiles, esp. for welding the individual "C"-links which are pre-bent and assembled to form a chain, uses at least two welding electrodes directly connected to the sec. side of a transformer device. Part of the sec. conductors which passes round the transformer core can be moved relative to tha core, the motion corresponding with the movement of the electrodes. The sec. conductors may be U-shaped and can be made of laminated or solid material. Alternatively, a core may be used for each sec., the two prim. windings being connected in series; or a laminated core with an adjustable air gap can be used. Gives better electrical stability esp. when two pairs of electrodes are employed.

Patent DE-2452120-A1 (DE)
Title: Amplifying and transmitting circuitry for analog signals - has digital logic elements and amplifiers with evaluation
Inventor: MOEGE MICHAEL ING GRAD
IPC: H03K7/08
Filed: 1974-11-02
Abstract: The circuitry generates two pulse duration and pulse frequency modulated square wave oscillations. Analog electrical signals are converted to pulse modulated electrical signals of constant amplitude and the processing to two complementary square wave signals is carried out in two parallel branches. They are brought together in terminal amplifiers. The impulse trains can be correlated in two AND gates. The transmission over two parallel branches ensures a high protection against interference. Signals cannot appear simultaneously in both transmission branches. Three phase shifting sections in the transmission path prevent self-interference in the terminal stages through simultaneous switching of the end stage transistors.

Title: Milliampere second relay for diagnostic X:ray appts. - includes log. amplifier to convert linear scale of comparators reference potentiometer
Inventor: KLAUMUENZER HARTWIG ING GRAD
IPC: H05G1/42
Filed: 1975-07-26
Abstract: The mA relay, for diagnostic X-ray apparatus, controls the switch-off of the X-ray tube's h.v. supply and allows the required mA product to be continually set on a logarithmic scale whilst avoiding the disadvantages of an electromechanical relay. A logarithmic amplifier is located between the tube current's integrator and the switch-off comparator. By applying a logarithmic mA product to the comparator the linear scale of the comparator's reference potentiometer is effectively converted into a logarithmic scale. The advantage lies in being able to select any mA value.

Title: Stored control programme changing system - operates by insertion of jump command leading to changed programme parts
Inventor: NAGEL KLAUS-JUERGEN DIPL ING
IPC: G06F9/26
Filed: 1976-08-12
Abstract: The jump command is formed by subsequently changing individual elements of the command to be amended into the possible direction. In the command to be amended only elements of the operational part are subsequently changed in the possible direction, while the address part is taken over unchanged as the address part of the jump command so formed. The programme store PROM can have two storage places, the first identified by a marking and the other also identified by a marking. The unchanged address of the jump command obtaining by changing the elements can form the indirect address for the changed programme part.

Title: Metal journal for wood roller shutter shafts - has sharp ended tube driven into wood leaving stub shaft bearing seat
Inventor: MIEDERHOFF FRANZ-JOSEF
IPC: F16C13/00
Filed: 1976-09-16
Abstract: A metal journal for the rolling friction bearings on a roller shutter with a wooden shaft is made of a tube with sharp edges at one end which is driven axially into the centre of the shaft. The part which penetrates into the wood can be circular, oval, square, triangular in section or ribbed. The circular journal end is separated from the embedded end by an upset collar in the tube wall or by a step from a larger dia. to the smaller dia. of the bearing seat. This creates an inexpensive journal and prevents splaying of the wooden shaft ends.
Patent DE-2652302-A1 (DE)
Inventor: HUWYLER SEBASTIAN DR RER NAT
IPC: C07C29/153
Filed: 1976-11-17
Abstract: Zinc is produced by reducing zinc oxide with methane in the preferred temperature range between 750 DEG C and 906 DEG C, the required heat energy being supplied by a high-temperature nuclear reactor. From the waste gas mixture thus arising, which consists of carbon monoxide and hydrogen in a molar ratio of 1:2, methanol is synthesised. For the methanol synthesis, the gas mixture is preferably brought to a pressure above 40 atmospheres and to a temperature in the range from 200 DEG C to 450 DEG C in the presence of a mixed catalyst. With this combination of process steps, pure zinc in the molten form and methanol are obtained at relatively low production costs and low energy consumption.
