Patent DE-2344663-A1 (DE)
Title: Physiologically orientated typist's desk unit - has typewriter set rearwardly and downwardly inclined to facilitate even touch on keys
Inventor: BURKHARDT SIEGFRIED
IPC: A47B21/00
Filed: 1973-09-05
Abstract: With the typewriter sloping down towards the back, the keyboard, which in the standard commercial machines rises upwards, is now set horizontally or even sloping down slightly towards the back so that the edges of the keys facing the typist are practically horizontal. When the hands are relaxed the back of the hands are parallel to the keyboard, which is particularly advantageous when using the machine, and can then be kept in this work position without any special effort, thereby easing the strain on the hand muscles. The typewriter is preferably set so that the vertical spacing between the typewriter support surface and the knees is about 5 cm so that the machine is as low as possible.

Title: Container with removable closure - has inverted U-shaped rim frictionally engaged by correspondingly shaped inwardly dished closure
Inventor: KNIZE ELMER JOHN
IPC: B65D43/04
Filed: 1973-10-15
Abstract: The U-shaped rim of the container is of smaller diameter than that of the container side wall. The closure member has a peripheral seating area whose cross-section has an inverted U-shape whose outer axial portion is equal to or shorter than its inner axial portion. The U-shaped seating area is dimensioned to be in frictional engagement with the U-shaped rim. The closure member has a central inwardly dished portion connected with its seating area via a short bend. The dished portion tends to return to a flat shape under the action of any pressure within the container thereby exerting an outward force on the rim and more firmly securing the closure member relative to the rim.

IPC: G01D5/26
Filed: 1974-01-23
Abstract: A light beam with a rotating polarisation plane is generated; with a reference signal whose phase is correlated with the rotating polarisation plane azimuth phase.

Title: Multicolour rotary offset printer - has surface roughness in centre of blanket cylinders to ensure precise register
Inventor: FISCHER HERMANN
IPC: B41F30/04
Filed: 1974-11-07
Abstract: The design eliminates the effect of possible folds in the blankets which may cause defective register during the repeated passages of paper through the stations with different colour printing. The tongue-shaped rough area in the cylinder centre decreases towards the cylinder edges, and the depth of the roughness amounts to 8-15 mu obtained with sand blasting. The roughness of the cylinders surface area contributes to improved adhesion of backing paper so that a lesser probability of blanket shift is achieved. In the development of the blanket cylinder surface, the rough area (18) stretches from front edge of the depression where the blanket clamp is set.

Title: X-ray tube with rotary anode - uses sphere as rotary anode mounted for rotation about two axes intersecting in their centre
Inventor: AMTMANN HERIBERT ING GRAD
IPC: H01J35/20
Filed: 1974-11-15
Abstract: The X-ray tube has a rotary anode of refractory metal, at least in the surface region, which is driven by a motor. The anode is in the form of a sphere (4) which is mounted in a rotary manner about two axes, the latter intersecting at their centre points and being preferably at right angles. The drive motor (5 to 10) may be of such design, as to hold the sphere magnetically in a floating condition between the poles (5, 6) and imparts to it a rotary motion. The motor poles may have a form of spherical sections at the ends facing the sphere, the common centre point of the sections coinciding with that of the sphere. The radius of the sections is so much greater as to form a gap during the sphere rotation.

Title: Oxidising materials contg sulphur, eg fuels - with reduced sulphur dioxide emissions, using fluidised bed contg alumina
Inventor: COPELAND GEORGE G
IPC: C01F7/743
Filed: 1975-04-04
Abstract: The emission of SO2-containing gaseous effluents in the oxidn. of sulphur-contg. substances, esp. fuels, is minimised by carrying out the oxidn. at 1200-1400 degrees F in a fluidised bed comprising particles of an alumina-containing nonrefractory clay, the bed being fluidised with gas contg. oxygen in stoichiometric excess for oxidn., and the bed containing alumina in stoichiometric excess to form aluminium sulphate from the sulphur oxides generated during the oxidn. Claimed feeds are coal, fuel oil, natural gas, lignite, oil shale, tar, sand and peat. The sulphur content is converted to SO3 which then reacts with the Al2O3 to form aluminium sulphate which, together with ash and other non-combustible materials, remains in the reactor and thus reduces atmospheric pollution. The solid sulphate reaction product is easily disposed without any pollution hazards.
