Patent DE-2900456-A1 (DE)
Title: Matrix printer with multiple heads - which are spaced uniformly at fixed intervals in line direction
Inventor: BAUR KARL
IPC: B41J2/385
Filed: 1979-01-08
Abstract: A matrix printer providing characters with a format of 'm' points in a line and 'n' points in column uses multiple printing heads to allow simultaneously printing of points within a column of different positions. The intention is to eliminate or minimise the distortion that may occur during character reproduction. In comparison with prior art devices using a single head based upon a fixed number of printing devices mounted in a single line, the unit is based upon multiple heads operating at different locations in relation to the text. The use of the multiple heads provides the possibility for printing actuator operation according to a more uniform pattern. The printing head actuator for the matrix are spaced at constant intervals within the specific line.

Title: Concrete chambered slab for river bed lining - has slabs with straight and centrally bent ribs on curves
Inventor: SCHNEIDER HORST
IPC: E02B3/14
Filed: 1979-03-01
Abstract: The assembly of concrete chamber slabs incorporates square chambers, with ends protruding beyond outside ribs by half chamber width, and with full-height end connecting tongues or grooves esp. for consolidating river beds. In providing curves, the assembly is made up from rectangular slabs which have straight ribs (19-21) in one group, but ribs in the other group (22-25) bent on the same side at the centre. This system enables slabs to be laid without gaps even in curved sectors.

Abstract: The burner for liq. fuel is based on a previous design and has a hollow, hemispherical, perforated distributor (1). It has its convex side facing towards the inside of a convergent cone shaped air-fuel mixture duct. The projected surface area of the distributor is greater than the duct outlet area, the latter beign chosen to give discharge at above flame propagation velocity. The combustion efficiency is enhanced by a deflecting baffle (2), or baffles, of thermally conducting heat resisting material. These baffles are fitted around the distributor, pref. underneath. The baffle shape, size and angle can vary.

Title: Rocket engine with two stages - has second stage moved axially from rest to running position to give clear space for jets
Inventor: SCHOEFFL RAINER ING GRAD
IPC: F42B15/36
Filed: 1979-03-24
Abstract: The rocket has a first combustion chamber (5), attached immediately behind the payload (1), which has nozzles (6) inclined at an angle to the axis. It is held on the end of a rod (8) which slides inside a second combustion chamber (2) mounted behind the first one. The second chamber has nozzles (3) at the end of the rocket and is ignited first.

Title: Slow-speed small synchronous motor - has rotor formed by two opposing interfitting sheet metal shells
Inventor: MERKLE PAUL
IPC: H02K19/08
Filed: 1979-08-27
Abstract: The motor has a stator with a coaxial coil and separate flux paths for the non-phase-shifted and the phase-shifted magnetic fluxes. The rotor is surrounded by the stator and the main part of it is formed as two half shells (18,19) of sheet iron or steel placed opposite to one another so that their side edges overlap and are pressed together.

Title: Electrode measurement to determine plates of capacitor - has AC electrode detection of voltage to determine outer capacitor plate prior to insertion in metal case
Inventor: OSTEROTH ALFRED ERNST ADOLF IN
IPC: H01G9/04
Filed: 1979-10-27
Abstract: The measurement technique is used to determine which is the outer electrode of a capacitor during production but prior to sealing in the case and is particularly important with regard to electrolytic capacitors where the outer must be connected to the can and where it is visually impossible to determine by inspection which lead out wire is the outer capacitor electrode. A measurement electrode (1) is located inside a screen electrode (2) which is connected to an overall earth screen (3). The capacitor (4) under test has the electrode connections (5,6) connected to an a.c. generator (7). The measurement electrode (1) is connected to the input of an impedance changer circuit (8), with output taken back to the screen (2), and followed by a frequency selective amplifier (9). The amplifier (9) is tuned to the measurement frequency and the output is rectified (10) and the voltage measured (11). The voltage differences for capacitor connection reverses (5,6) are used to determine which electrode is the outer. Differences with a ratio of 37:1 are obtainable.

Title: Hide splitting machine - with waisted drive roll deflected in transport direction by set screws
Inventor: DORSTEWITZ RAINER DIPL ING
IPC: C14B1/18
Filed: 1979-12-10
Abstract: A machine for the processing (splitting) of hides, skins and leather feeds the workpiece between a drive roll and a back-up roll. The back-up roll has a central waisted section which is gradually reduced in diameter e.g. by 10%. Lateral guide strips one straight and one curved by adjustable setscrews, impose a deflection in the direction of transport to the drive roll. This ensures that the peripheral areas of a skin, which are longer than the central areas, are transported at a greater speed and th4ow no folds when treated by the splitting blades.

Abstract: The mandrel rod is coupled to the piston of a pneumatic cylinder (PC), which is connected via a closed circuit of air pipes to a second, double-acting PC (I). The piston in PC (I) is coupled by a crank mechanism to one of the two pilger rolls. The air pipes connecting the two PC are pref. telescopic, and are connected to a compressor via two non-return valves operated by remote control. The mill is used e.g. for the hot rolling of seamless tubes, (where the productivity is improved). Obsolete pilger mills can easily be altered to modern, automatic, high-prodn. mills. PC (20) contains a double-acting piston (16) with its piston rod (17) coupled via crank (19,18) to one (2) of the pair of pilger rolls. The connecting rod (19) is coupled to rod (17) via a slide (31). PC (20) has air pipes (14,23) connected via telescopic joints (21,24) to air pipes (22,25) feeding cylinder (9). Roll (2) drives piston (16) and thus feeds air through pipes (22,25). Pipe (22) does not interfere with piston (15), which is a limit stop for piston (7). Compressor (28) and non-return valves (29,30) compensate for air leaks in pipes (14,23). Piston (7) carries spindle (5), on which is the mandrel rod and hollow tube blank (1).

Title: Distillates obtd. from heavy oils contg. asphaltene(s) and metals - by donor solvent hydro-visbreaking and fixed bed hydrotreatment
Inventor: SIMO THOMAS DR
IPC: C10G47/22
Filed: 1980-05-30
Abstract: Heavy oils, contg. asphaltenes and possibly high concns. of metals, are converted to fuel and petrochemical-precursors by donor-solvent-hydrovisbreaking (DSV) followed by fixed- bed catalytic hydrotreatment of one or more distillate fractions of the DSV prod. In the process claimed, distn. residue (II) from 18V prod., and donor solvent oil (III) from hydrotreater prod. are recycled to join fresh feedstock (I) as DSV feed. For treatment of crude oil, shale oil, coal tar, tar sands tar, bitumen, etc. Unlike processes including liq. phase hydrotreatment, a catalyst regeneration process is not needed, and there is no yield loss as on discharging a once-through catalyst. Demetallisation occurs (by distn.) with min. H2 consumption. The net yield of DSV residue is adjustable to requirements.

Title: Electromagnetic brake for low power motor - reduces weight by using segmented brake blocks around ventilating fan wheel
Inventor: HUSSMANN HELMUT
IPC: F16D55/02
Filed: 1980-07-28
Abstract: The brake appts. has a conical brake lining mounted on the ventilating fan wheel attached to the motor's shaft. A braking ring is moved against the action of a spring by an electromagnetic field towards the braking lining on the fan wheel. Alternatively, the fan may be moved against a fixed braking ring. The brake lining consists of numerous blocks (9). Each block is situated between two adjacent blades of the fan wheel. The blades of the wheel are joined together in pairs by webs (8). The webs act as seats for the brake blocks. Each pair of joined blades is not joined to its neighbouring pairs of joined blades. The advantage of the arrangement lies in the reduction of the weight of the rotating brake lining.
