Title: Breast prosthesis - produced by vulcanising silicone rubber between plastic foils in slit cup-shaped mould
Inventor: RECHENBERG CORNELIUS
IPC: A61F2/50
Filed: 1979-01-22
Abstract: Parent patent described a breast prosthesis consisting of two plastic foils, enclosing a two-component silicone rubber compd. which are given a cup-shape in a mould. A quantity of the two-component silicone rubber cpd. which corresponds to the volume of the mould cavity is filled between the plastic foils through a filler opening at the welded seam. The bottom part of the mould is closed by the top part finally only just before the cpd. is vulcanised in the mould. This ensures that no air bubbles remain and that the prosthesis has a smooth exterior.
Patent DE-2906528-A1 (DE)
Inventor: CRONEWITZ THEODOR DIPL ING
IPC: A23K10/37
Filed: 1979-02-20
Abstract: Process for obtaining beet pulp of high dry-solids content from a sugar extraction process by mechanically pressing the pulp, mixing salts of polyvalent cations, an acid or both with the pressed pulp, further pressing the admixture and thermally drying the admixture. The salts of the polyvalent cations are preferably calcium chloride, aluminum chloride and ferric chloride and are added in an amount of from 0.5 to 10%, preferably from 1.5 to 4%, relative to the pulp dry-solids content. The liquid from the second pressing can be concentrated by evaporation and at least part can be recycled to produce the initial solution of the salts. The remainder of the concentrated liquid can be added to the pressed admixture before or after drying to further increase the dry-solids content.

Title: Removing contaminants from combustion plant fumes - by reacting sulphur cpds. with liq. ammonia
Inventor: GATZKE HORST DR ING
IPC: B01D53/34
Filed: 1980-02-15
Abstract: Atmospherically harmful components such as sulphur cpds., nitrogen cpds., F and Cl in the fumes from industrial combustion plant are removed by intermittently spraying jets of liq. NH3 into the departing fumes. The NH3 concn. can be adjusted to varying S contents in fuel and treated minerals, as may be the duration and/or frequency of the individual impulses. Provided they do not react with NH3, further reagents may be injected simultaneously to deal with other contaminants. The spray equipment may be combined with a heat exchanger for recovering waste heat from the fumes, with a shape corresp. to the fume outlet. Used for combustion plant in power stations, casting shops, brickworks etc. The resulting prod. is useful as a fertiliser and does not involve the filtering and disposal problems arising with the known lime-dust treatment of fumes.

Title: Closing the holes in a tunnel-kiln roof - with hemispherical plates lowered and raised by suspension cable
Inventor: WOYCZECK GUENTER ING GRAD
IPC: F27D17/00
Filed: 1980-03-18
Abstract: A tunnel kiln has holes in its roof through which hot air can pass into an enclosed chamber above the roof to be extracted, mixed with fresh air and used in drying plant and recuperators. These holes can be individually closed or opened by plates having a semi-spherical side directed towards the hole to seal it off. The plates are suspended from cables attached to a lifting unit, which includes a horizontal bar cooperating with a crank drive which moves the bar to and fro. The soot which is formed when a firing stage is followed by a reducing stage is prevented from emerging more effectively than with known manually operated steel or ceramic sliders covering a set of holes.
Patent DE-3015290-A1 (DE)
Inventor: HINGER KLAUS-JUERGEN DR ING
IPC: C02F11/10
Filed: 1980-04-21
Abstract: In a procedure and an installation for the incinerating of sludge, predried sludge is dried to residual moisture by the addition of heat in a first processing step and then pyrolized by the continued addition of heat and the exclusion of air in a second processing step, with the pyrolysis gas obtained being used at least partially to generate the hot fumes required for heat input. To incinerate sludge in a way which is compatible with the environment, saves energy and is inexpensive, the predried sludge is carried co-current with the hot fumes in the first processing step and the so-dried sludge is then, in the second step, carried in countercurrent flow to those same fumes. An evaporation worm-gear machine (1) with a worm shaft (9) capable of being driven by rotation, with at least one spiral coil (14), which is placed in a housing (3) serves to carry out the first processing step, while a pyrolysis rotation cylindrical reactor (2) with an opposite direction of movement of the material which is in the hollow-built worm shaft (9) serves to effect the second processing step.

Title: Electromagnetic wave transmission reflector - has single-phase or multiphase curable material e.g. synthetic resin filling in space between two membranes
Inventor: BERGMANN KONRAD DR ING
IPC: F24S23/70
Filed: 1980-05-29
Abstract: Reflector body of the type used in electromagnetic etc. wave transmission engineering and in solar energy engineering has a surface approximating to a section of a paraboloid of rotation and is designed to overcome the high costs involved in earlier models for the tensioning ring and the necessity of maintaining a minimum differential pressure. Thus, the intermediate space between the two membranes stretched tightly in a tensioning device is filled with a single- or multi-phase curing material, pref. a synthetic resin material, or a foamed resin, that is made to flow during equal deformation of the two membranes and the resultant differential pressure, and then hardened by subsequent deformation of the membranes to form a rigid, compound body comprising the membranes and the filler that retains its shape after removal of the differential pressure and which can be then released from the tensioning device.

Title: Removal of carbon di:oxide from natural gas - esp. from wells near sea coast, by washing with sea water in submarine absorber
Inventor: COOK CHARLES FALK
IPC: C07C7/11
Filed: 1980-07-22
Abstract: A process for removing water-sol. impurities from gas streams is esp. suitable for removing CO2 (pref. present as 20-95 vol.%) from natural gas from a well near the sea coast. An absorbing vessel contg. sea water is immersed in the sea, on or near the sea bed. A stream of natural gas enters at the bottom and, in rising, induces a parallel inlet flow of sea water. CO2 is absorbed, and the CO2-contg. water is rejected into the sea, pref. at a point where the sea water density is at least .0002 g/ml less than that of the effluent, so that the latter disperses over a wide area of the sea. The purified natural gas is collected for further processing. Costly absorbents and plants are not required. The equipment is cheap in that (a) a high-pressure vessel is not needed (the operating pressure being close to the local hydrostatic pressure); and (b) the absorbing water flow is induced and pumps are not required. Pipes and tanks are not necessary for the CO2 removed. The purified gas is of much lower vol. than the crude gas, so that transport costs are reduced: this is important if CO2 is absorbed at a well far off shore.

Title: Automated shunting exit for railway marshalling yards - confines first brake regulator to small steps and derives criterion for incompletely-filled tank goods wagon braking
Inventor: MUELLER HANS-JOACHIM ING GRAD
IPC: B61K7/00
Filed: 1980-09-25
Abstract: Provision is made for regulating tank wagons which are not completely filled, in automated run-off layouts, in railway marshalling yards. At the first brake, comparison is made between actual regulated free play and standard regulated free play. When tank wagons not completely full are first decelerated. The regulator for the brake, in switching back, is confined to small braking stages. A criterium is derived, for transmission to further control and regulating devices. A simple process facilitates early recognition of tank wagons which are not completely full, and makes provision for varied brake action and running conditions.
