Patent DE-2119645-A1 (DE)
Title: Drum dryer - adjustable blade arrangement enables optimum material and heating gas flows to be maintained
Inventor: ROEMER GERHARD DIPL ING
IPC: F26B11/04
Filed: 1971-04-22
Abstract: Farm products such as grass, grain etc., are dried in a drum type provided internally with blades arranged on pivot shafts, by means of which the material flow through the dryer is mechanically influenced. Pref. the blades are externally and steplessly adjusted between end positions and are arranged either singly, or in pairs or in banks throughout the drum. The pivot shafts for the various straight or shaped blades and blade arrangements are parallel, transverse or radial to the drum axis and can be operated externally via levers and couplings by manual, hydraulic, pneumatic or spring assisted means. Variation in blade inclination and adjustment and/or rotational speed of drum ensures optimum material and heating gas flow conditions, depending upon the particular material and its condition without undue overheating.

Title: Hydrogen prodn. by thermal decomposition of steam - using a metal oxide in a low oxidation state
Inventor: KNOCHE KARL-FRIEDRICH PROF DR
IPC: C01B3/06
Filed: 1973-05-09
Abstract: Water vapour is reacted in a first reactor pref. with FeO, whereby hydrogen is liberated and Fe2O4 is produced. The latter is reacted in a second reactor with an oxidising agent other than oxygen (pref. HCl+Cl2) to produce a cpd. in a higher valence state (pref. FeC3); this cpd. is decomposed (in another part of this reactor) to a cpd. in a lower valence state (pref. FeCl3 is decomposed in FeCl2 with partial liberation of chlorine). The latter cpd. is subsequently hydrolysed to restore the original lower oxide (pref. FeO). This process is economical when a high-temp. nuclear reactor is used as a heat source. The process is carried out in a closed circuit so that noxious, corrosive gases do not escape.
Patent DE-2343306-A1 (DE)
Title: Installation unit for exchanging steel mill rollers - has roller extraction trolley and support frames for replacement rollers
Inventor: BRAHM WALTER IM
IPC: B21B31/10
Filed: 1973-08-28
Abstract: To reduce down time when exchanging cylinder rollers, a cross slide arrangement adjacent to each rolling station, is provided. It consists of a trolley which moves in the axial direction of the cylinder rollers. Between trolley and rolling mill, support frames can be moved parallel to the direction of the rolling operation. To exchange a pair of rollers, the extractor trolley pulls the cylindrical rollers axially out of the rolling station onto an empty pair of support frames. The frames are then moved until a new roller pair on identical support frames is in line with the installation position. The extractor trolley is now operating in reverse by moving the new rollers into their working position.

Title: Fishing rod handle attachment - spring loaded mechanical rocker-arm device which automatically jerks rod
Inventor: BECK HUBERT
IPC: A01K97/11
Filed: 1974-03-12
Abstract: The attachment has a bar to which the rod is attached, and consists of a flexible tension-piece at the front, and a sleeve at the back. The pole of the device is pulled downward by means of manual pressure into the river bank which should be as flat as possible, until the stop-piece is just above the ground. The bracket-part of the device points towards the water. the rod attachment bar is lifted up in a radius-shaped curve over the pivot pole fixed on both sides of it, until the pivot pole touches the adjustment screw, which is screwed outwards to that the rod attachment bar exerts the pressure on the screw and rests against the vertical pole. The fishing line is cast so that it is relatively taut. The adjustment screw adjusts the dead centre position, when the safety clamp can be carefully removed. When the fish bites on the bait, the fishing rod jerkcs backwards into an oblique position.

Title: Pin type electrode setter for printed circuits - has mechanically guided circuit board guide, stylus and template guiding mechanism
Inventor: LOTTMANN JOHANN
IPC: H01R43/20
Filed: 1974-04-19
Abstract: The setting machine used for inserting contact pins into the prepared holes in the printed circuit plates has a mechanical locating system for the pin insertion which is manually operated. This setting machine is used for producing a large quantity of circuit plates of the same pattern. The support plate for the printed circuit board is mounted on rods, which slide in bearing sleeves and enable the support plate to be moved with little effort in two coordinate directions.

Title: Accessory grenade for small firearms - is used to incapacitate criminals without lethal consequences
Inventor: HACK HEINZ
IPC: F42B30/04
Filed: 1974-09-24
Abstract: The accessory grenade is used for firing from semi-automatic and other small arms. This grenade is loaded with gases for incapacitating criminals reliably without lethal results.

Title: Deflection unit for in-line colour TV receiver - has rear edge to left and right of neck deviating from circle to simplify production
Inventor: KRATOCHVIL FRIEDRICH
IPC: H01J29/76
Filed: 1974-12-21
Abstract: The deflection unit, for an in-line colour television receiver, has a conical core ring around the neck of the tube and shaped at its rear edge such that the vertical deflection field is reduced. The core (7) has its rear edge (11) to the left and right of the neck (3) drawn outwards to deviate from its otherwise circular form such that it has a greater distance from the neck at these places than elsewhere around its circumference.

Title: De-scaling of metal alloy strip - peels off scale with cutting blades acting on both sides of strip
Inventor: WUETHRICH PAUL
IPC: B21B45/04
Filed: 1975-02-25
Abstract: The machine removes the scale from hot rolled strip and the skin from cast strip. The strip is fed from a roller through the feed rollers to the cutting blades which are mounted above and below the strip in a housing. The blades are rigidly mounted in blocks which are supported in the central block. The central block is mounted on wedges in the housing so that a transverse movement of the block, which is effected by the handwheel, raises or lowers the cutting blades to suit the thickness of the strip and the depth of cut necessary to remove the scale or skin.

Title: Quadraphonic transmission over F.M. source - provides amplitude has phase correlation using auxiliary carrier to provide phase relationships
Inventor: HEMSING SIEGMAR
IPC: H04H20/48
Filed: 1975-09-26
Abstract: The transmission of a quadraphonic programme over a frequency modulated radio transmitter uses a quadraphonic coder to process the four signals over preamplifiers consisting of impedance converters, level regulators, frequency dependent amplifiers with an RC time constant of 50 microseconds and a phase inverter. 180 deg. outputs relative to the input signal are generated, summed and transmitted over an intermediate amplifier. After delay the signals are processed in a passive summing matrix. The four 0 deg. outputs are modulated with a 38kHz carrier but with different phases. This auxiliary carrier is generated by doubling the output of a 19 kHz oscillator and is introduced over transistor stages ensuring phase relationships of O (plus-or-minus) 45 deg. and 180 deg. (plus-or-minus) 45 deg..
