Title: Process and arrangement for the production of activated charcoal
Inventor: HELLWIG GERD
IPC: C01B32/336
Filed: 1982-08-16
Abstract: A process and an arrangement for the production of activated charcoal are described, preferably with the use of the waste products produced in thermal power stations, such as lignite ash, and with utilisation of the heat of reaction available there. The process according to the invention can be used for all processing stages belonging to the production of activated charcoal, of granular fossil substances. The aim of the invention is to produce activated charcoal with a significantly reduced energy consumption and reduced expense in terms of equipment and reduced technological effort. For this purpose, a process known per se for the production of activated charcoal is integrated directly into the equipment of a thermal power station, by preferably feeding the lignite ash produced to the activator and also passing a part-stream of the flue gas of the steam generator directly through the activator. The exhaust gases of the activator including the suspended particle fractions thereof are blown via the coal pulverising mill, and the activiation gases are blown directly, into the steam generator firing chamber, and are there used calorically. <IMAGE>

Patent DE-3236244-A1 (DE)
Title: Piezoelectric drive
Inventor: SPRINGER JOHANN DR RER NAT
IPC: H02N2/04
Filed: 1982-09-30
Abstract: A thin-walled ceramic tube of ferro-electric material is provided with electrode linings on its two shell surfaces. Between them there is a permanent polarisation. As a result of the piezoelectric effect, the pipe becomes shorter or longer when a voltage is applied. This length change is used for drive purposes. A pipe has the maximum possible mechanical stability. If the electrode linings do not reach completely to the end face, the flashover resistance can be substantially increased and the path for leakage currents extended. Relatively large forces can be applied if a plurality of such pipes are arranged mechanically in parallel. This is possible both side-by-side as well as concentrically, one inside the other. <IMAGE>

Patent DE-3319787-A1 (DE)
Title: Corner connection of profiled rods
Inventor: WAEHLING HANS-GERHARD DIPL ING
IPC: E06B3/96
Filed: 1983-06-01
Abstract: In a corner connection of profiled rods having a limb which lies in the plane of view and a limb which projects out of the plane of view at a distance from the limb edge, the profiled rods abut against one another in a mitre joint which forms the corner region and are permanently connected to one another there. In order to form a corner connection which can be produced at a low manufacturing cost, a mitre recess, which is arranged in the limb of a continuous profiled rod lying in the plane of view, originates from the edge of this limb and runs as far as the projecting limb, is transformed by bending the profiled-rod regions which extend on both sides of the mitre recess opposingly to form a mitre joint which originates from a chamfering zone.
Patent DE-3323173-A1 (DE)
Title: Process for producing stators for eccentric spiral pumps
Inventor: JAEGER ARNOLD
IPC: B29C45/14
Filed: 1983-06-28
Abstract: According to this process, stators with casings having beads are to be produced. In order to be able to use smooth tubes or curved plates for the casings, according to the invention the beads are moulded within the mould by introducing the elastomer to be surrounded by the casing, and specifically with the aid of abutments which are located within the mould. The mould for producing the stator with the internal body of rubber or the like thus serves simultaneously for shaping the casing in the manner of a thermoforming mould.

Patent DE-3325695-A1 (DE)
Title: Radial fan
Inventor: JENTZSCH WERNER DIPL PHYS
IPC: F04D29/28
Filed: 1983-07-14
Abstract: In the case of a radial fan with axial intake and axial expelling of the cooling air flow the axial deflection of the cooling air on the fan outlet is to be improved. At the same time where the fan is used in pipe-cooled electrical machines the velocity distribution inside the deflected air flow on the fan outlet is to be rendered uniform. This is achieved by means of dual chambers provided parallel to the radial blade ducts, which chambers are formed by the arrangement of auxiliary blades (6) between the carrier plate (2) and an auxiliary plate (7) essentially parallel to this and are designed narrower in an axial direction and longer in a radial direction than the blade ducts and which produce an air flow (8) which follows the outer periphery of a curvature (9, 10) on the fan outlet and thereby deflects the main air flow (4) emerging from the blade ducts in an axial direction. The dual chambers may be provided inside the fan on the inside of the carrier plate (2) or outside the fan on the outside of the carrier plate (2). <IMAGE>

The substances are prepared by transesterification of a condensation product, which is obtained without the aid of a solvent, of 2 mol of fatty acid methyl ester (R'= R-CH2-) or of fatty acid methyl ester and methyl benzoate (R'= phenyl-) with an alcohol (R''-OH).
Patent DE-3337848-A1 (DE)
Title: Tear-open envelope with letter extraction
Inventor: GRUBMUELLER HANS-GEORG
IPC: B65D27/38
Filed: 1983-10-18
Abstract: The tear-open envelope with letter extraction is a normal letter envelope of any shape which, however, can be rapidly opened without any auxiliary appliances by means of a fixedly installed thread and at the same time moves the contents of the envelope out of the latter. The tear-open thread can be fitted at any lengthwise edge of the letter envelope (cf. stylised figure). I propose, however, that it should be fixed, viewed from the rear, in corner B to C. At point C a small, self-adhesive dot is fixed on the thread within the envelope and, after tearing-open of the envelope, draws out the contents adhering to the thread. To tear the envelope open, point B is torn off the envelope. As a result the user is holding the thread, which is to be drawn away from the envelope in the direction of corner C. In the course of the movement described, edge B to C is quickly and reliably split by the thread. At the end of the tearing operation, the adhesive dot described moves the contents of the envelope out by means of further pulling. Letter envelope which contains a fixedly installed thread in an edge between two corners, by means of which the edge can be split. At the end of the thread is an adhesive dot which draws the contents of the envelope out with it. <IMAGE>

Title: Process for producing liquid pig iron and reduction gas in a tapping generator
Inventor: BUCHWALDER JOACHIM DIPL ING
IPC: C21B13/00
Filed: 1984-05-18
Abstract: The pig iron produced according to the process of the invention is suitable for direct further processing into steel, for example in a converter. Furthermore, it can be used to generate a high-quality reduction gas for producing sponge iron. The object of the invention is to develop a process in which the residence time of the sponge-iron particles in the high temperature zone is extended to such a degree that a temperature level of the smelting products of over 1400 DEG C is achieved while simultaneously reducing the head gas temperature. According to the invention, there is produced, in the tapping generator above the slag layer, a relatively compact bed of fuel and sponge-iron particles in defined particle size ratios and in a delimited spatial region, which bed serves, at the same time, as a gas-distribution device for a fluidised bed/fly ash cloud system which forms above the bed and which is known per se. <IMAGE>

Title: Device, in particular for displacement measurement
Inventor: SCHOTT WALTER DIPL ING
IPC: G01B9/02
Filed: 1984-06-15
Abstract: Using the device, in particular for displacement measurement, it is possible to increase the resolution of interferential displacement-measuring systems by means of optical methods. Resolutions of  lambda /8,  lambda /12,  lambda /16, ... can be realised. The increase in resolution is achieved by means of multiple passage of the laser beam through the measurement path. Symmetric and asymmetric devices are possible. Furthermore, the beam path can extend in one or more planes. It is preferred to use triple strips and triple prisms as tilt-invariable reflectors. <IMAGE>
Patent DE-3430577-A1 (DE)
Title: Sensor for measuring the volumetric flow of a breathing gas
Inventor: ABENDROTH MANFRED DR ING
IPC: G01F1/32
Filed: 1984-08-20
Abstract: The invention serves to provide a sensor for measuring the volumetric flow, which can preferably be employed for monitoring automatic, controlled respiration but which is also suitable for recording other, small volumetric flows of gaseous media. In the case of low flow rates the known sensors which operate on the principle of the Karman vortex street are characterised by periodic fluctuations, an inadequate signal-to-noise ratio and an equally unsatisfactory linear relationship between vortex frequency and volumetric flow. It is the aim and object of the invention to eliminate these unfavourable properties, so that there is provided a sensor having a high measuring accuracy for a wide range of flow rates, including the weak movements of gas. This is achieved with a sensor whose measuring section is provided on the inlet side with a parabolic or hyperbolic narrowing which brings about improved formation of vortices of one of its downstream flow bodies having a prismatic cross-section.
Patent DE-3442060-A1 (DE)
Title: Restoring device for damaged facade claddings consisting of ashlar slabs
Inventor: DOGANOFF ILIJA DR ING
IPC: E04F13/08
Filed: 1984-11-17
Abstract: The restoring device has dowels arranged in the joints between the ashlar slabs, which dowels are anchored in the wall of the structure, prevent the ashlar slabs from falling out and are used for anchoring a ventilated facade cladding which is to be newly installed. Restoring work is usually performed by ripping out the ashlar slabs and fitting a ventilated facade. The ripping-out work requires a large outlay in terms of time and money and gives rise to noise and dust formation. In the case of a known restoring device which does not require ripping-out work, a very large number of dowels which are subjected to strong bending stresses and have comparatively large diameters are used. According to the invention, the dowels are accommodated in metal or plastic vertical bracket plates, arranged in the joints at comparatively very large vertical spacings, and are hardly subjected to bending stresses. The ashlar slabs can be supported vertically and horizontally by simple metal or plastic components. The restoring device is used to eliminate damage resulting from ashlar slabs which have been produced and/or mounted in an incorrect manner.

Title: Ground contact compensating device for ladders
Inventor: ERNST SEBASTIAN
IPC: E06C7/44
Filed: 1985-01-31
Abstract: A ground contact compensating device for ladders is presented, in which at least one of the uprights of the ladder can be extended in the axial direction by an extension piece, and even slight unevennesses of the ground contact area, which lead to considerable oscillatory deflections at the upper end of the ladder, can be compensated by the extension piece assigned to the respective ladder upright being steplessly adjustable and it furthermore being guaranteed that the extension piece is fixed in its respectively adjusted extension position absolutely securely and, with increasing loading of the ladder, in particular by the weight of a user, automatically with increasing clamping force in relation to the ladder upright by arrangement of a clamping device. This takes place according to the present proposal by the clamping member of the clamping device being supported on at least one of the ladder rungs and, with increasing ladder loading, being subjected to an increasingly great tipping force which acts as a clamping force on the extension piece. <IMAGE>
