Patent DE-3916705-A1 (DE)
Title: Process for recovering heat from flue gases
Inventor: HEBECKER DIETRICH PROF DR SC T
IPC: F23J15/04
Filed: 1989-05-23
Abstract: The process can be applied to recovering heat from flue gases and, owing to an integrated flue gas desulphurisation, is particularly important for sectors having high emissions of flue gas pollutants. According to the invention, the flue gas is brought into direct contact with a fluid circulated heat carrier which absorbs sulphur-containing flue gas pollutants and water vapour, boils above 100@C and, in comparison to water, has a lower water vapour partial pressure. The heat carrier is heated to temperatures above 100@C and the flue gas is brought to a temperature sufficient for discharge to the open atmosphere. <IMAGE>

Patent DE-4007079-A1 (DE)
Inventor: BOSSLET KLAUS DR
IPC: G01N33/84
Filed: 1990-03-07
Abstract: The invention relates to monoclonal antibodies (MAbs) which bind with high specificity and avidity to water-soluble complexones such as ethylenediaminetetraacetate (EDTA) or diethylenetriaminepentaacetate (DTPA) and after complexation of EDTA or DTPA with metal ions retain their high avidity and specificity for these complexones. These MAbs can therefore be used, for example coupled to filters or other supports, for removing toxic heavy metals which are complexed with EDTA or DTPA. Furthermore, these MAbs are suitable as components of immunoassays (RIA, ELISA etc.) for the quantitative detection of EDTA and DTPA in aqueous solutions.

Title: Wear resistant castings - formed by diffusive or penetrative coating by hard materials in casting process
Inventor: LANGE KARL
IPC: B22D19/08
Filed: 1991-03-23
Abstract: Wear resistant castings of steel or grey iron are made by introducing hard materials and/or sinter hard metals into the mould prior to casting the molten metal. The novelty is the form and means in which the hard surfacing material is put into the mould, i.e., either hard material particles bound in a matrix or massive sinter hard metal as a brick or briquette. Thus, the molten metal is poured into the mould which contains the hard material package giving rise to coating by penetration (Variant A) or by diffusion (Variant B). Also claimed is geometry of the hard material which is profiled or arranged in a lattice form, and attached to the walls by fixing, interlocking, arranging two or more packages side-by-side, or above and below each other. USE/ADVANTAGE - Useful in casting components which are subjected to strong frictional surface forces, eg., ball mill spheres. The hard material is distributed in layers of uniform and easily controlled thickness, giving an abrasion resistant surface whilst retaining the essential properties of the core metal.

Title: Superheated steam temp. regulation - uses post-injection enthalpy to allow controlled spraying of water into superheater even on saturation curve and in wet steam region
Inventor: REICH WERNER DR ING
IPC: F22G5/12
Filed: 1991-05-30
Abstract: Satd. steam from a separator (O) passes through two parallel superheaters with elements (e.g. 2,6,11) connected together in series by mixer tubes (4,9) into which water is injected (14,15).

Title: Shut=off appliance for damaged pipes - from which gases, liquids or high-pressure oil-gas mixt. escapes, includes sawing through pipe and diverting fluid flow
Inventor: GERVENS HANNS
IPC: E21B29/08
Filed: 1991-06-05
Abstract: This is a shut-off appliance for liqs. and gases in pipes, and in partic. for escaping hazardous matter such as toxic gases, environmentally harmful liqs., and high-pressure oil/gas mixt. The appliance has a container (1) that forms a circular saw or a face-milling cutter. It has saw teeth (2) or cutting edges (2) on its upright outer surface and can be rotated about its axis and supported in a slide (3) against pressure. This "dish-saw" (1), with the slide (3), is connected by a rod (9) to the drive housing (5) and drive (6), and, in the housings (4,8,19), can be pushed against the pipe (24) by a drive arrangement (12) with a rod (11). The "dish-saw" cuts through the pipe, and the flow is diverted at the same time. A number of features and variants are claimed. USE/ADVANTAGE - The appliance is light and readily handled, and can be kept ready for use where it might be needed. It can shut off the damaged pipe upstream of the damage and safely divert the flow; flow pressure after shutting off is not unduly increased. Flow diversion can be to a tank or elsewhere, and, after shutting off, production or other work, including repairs, can be done.
