Patent DE-2601299-A1 (DE)
Title: Bell-shaped tool for drills and lathes - has tool carrier with end cross slide for workpiece dia. adjustment
Inventor: BAIER GERHARD
IPC: B23B29/034
Filed: 1976-01-15
Abstract: The bell-shaped tool is for drilling and turning during turbine housing production. A cross-slide (7) carries the tool and is driven by and advancing gear through the main spindle. An additional tool carrier (5) is coupled to the front of the drill bell (1) via a cross beam (2). This has a tapering diameter leading into the cross-slide. The advance gear (4) is driven through the central borehole of the drill bell. Selectively operable couplings (9) are used to effect advancing movement of the cross-slide and tool slide. This cross-slide avoids the need to replace the head of the drill bell or the bell itself when chaning from machining large to smaller diameters.

Title: Salvage method for sunken vessels - uses ballast stable open buoyancy elements raised by gas
Inventor: KLEMM WOLF
IPC: B63C7/12
Filed: 1976-01-20
Abstract: Salvage procedure is for the raising of sunken craft, and the sealing of fluid surfaces via ballast-stable open buoyancy elements. The buoyancy elements consist of domed components open at the bottom, which have no self-buoyancy, are self-erecting, and are maintained position-stable by ballast. When immersed and filled, the components sink to the bottom, and remain there upside down, until they are raised by a fluid or gaseous buoyancy medium, which is fed through apertures below them. The gas within the components expands during raising, and can escape through the open lower side. Due to this, the external shape of the buoyancy elements remains the same at all depths.
Patent DE-2608507-A1 (DE)
Title: Phosphorus prodn. by redn. of phosphate with carbon - in molten iron in presence of silica
Inventor: BROTZMANN KARL DR ING
IPC: C01B25/027
Filed: 1976-03-02
Abstract: Prodn. of elemental P by reaction between a phosphate and carbon in presence of silica is carried out in a liquid medium heated by combustion of a low-grade fuel, such as coal dust, a heavy oil or a distn. residue. The pref. medium is molten iron heated to 1350-1500 degrees C (esp. 1400-1450 degrees C). The cost of the process is much lower than in the case of the conventional processes employing expensive fuels or electric energy. The iron melt heated to 1350-1500 degrees C (pref. 1400-1450 degrees C) is an ideal reaction medium as at these temps. the crude phosphate, e.g. Ca3(PO4)2, is first reduced to calcium phosphide, which then readily reacts with more Ca3(PO4)2 forming CaO and elemental P.

Title: Tomography appts. with rotatable measuring assembly - has cables coiled around drum and fixed to spring band parallel to cables
Inventor: ZINK RODERICH
IPC: H02G11/02
Filed: 1976-05-31
Abstract: Tomography appts. comprises an X-ray measuring assembly (1, 2), consisting of an X-ray source and detector, with a frame for rotating it about an axis perpendicular to the plane of the body section. A transducer for converting the detector signals to a body section image is connected, as is also an X-Ray generator, to the meauring assembly by cables (K). The calbes are wound spirally like a clock spring around a drum (5) and fixed to a spring band (12) parallel to the cables. These together with the spring band are attached to a stationary support (13) and to the drum and on the drum itself. The cable length between the two points of attachment is equal to the desired angle of rotation of the measuring assembly.

Title: Variable range atmospheric gas analyser - with adjustable slide varying area of sensitive surface exposed
IPC: G01N27/12
Filed: 1976-06-04
Abstract: The sensitive surface of a gas analyser, which produces an electrical signal from embedded electrodes, has an exposed area which can be varied by movement of a slide with openings of varying sizes. Used for the detection and measurement of specific contaminants in the atmosphere, e.g. hydrogen sulphide. Higher gas concns. can be determined accurately without the signal output reaching saturation level. In H2S detection, a concn. of 0.5ppm. in air gives a 500mV signal from an exposed surface of 16mm2. The same signal output is obtd. from a 2ppm. concn. using an exposed surface of 4mm2.
Patent DE-2626180-A1 (DE)
Title: Leak proof joint for enamelled or ceramic pipes - has surface enamel on coupling sleeve heated until plastic to mould to pipes
IPC: F16L49/02
Filed: 1976-06-11
Abstract: The connection of enamelled pipes of equal dia. is produced by pushing the two pipe ends together inside a coupling sleeve. The coupling sleeve which is also enamelled is heated until the surface layer of the enamel starts to melt. The plastic enamel forms a leakproof joint with the enamel on the pipes. So that only the surface layer of the enamel becomes plastic when heated, the first coat of enamel on the pipes and coupling sleeve has a higher melting point. A substance which reduces the melting point on the surface of the enamel layer can also be used.

Title: Transversal digital filter - uses triangular matrix of series adder subtractor stages to provide LSI filter
Inventor: STORZ WERNER DR
IPC: H03H17/06
Filed: 1976-09-28
Abstract: The digital filter of the transversal type is based upon a matrix of elements that allows ready construction of serial adder/subtraction functions in a form suited to large scale integration. The resulting circuit allows the centre frequency and the band width to be readily adjusted. Adder/subtractor modules are arranged in the form of a triangular matrix with inputs and controlled by signals applied to columns by a control stage. The binary input is processed by the stages to present the filtered output in a serial mode. The output stage responds to provide an output to a normalising stage.

Title: Wind powered electricity generator - has stiffened construction to withstand storm conditions and weather protection for electrical generator
Inventor: BRODERSEN KARL
IPC: F03D3/04
Filed: 1976-10-05
Abstract: The generator has a stationary central base (1) with a rotating tower (3) on top of it. The top end of the base (1) is thickened and supports the tower on two rings (4, 5) of large ball bearings. These carry the weight and also absorb the turning moment exerted on the base. A shaft through the tower carries turbine blades (10) outside the tower and drives an electrical generator (17) through bevel gears and a final gear box (16). The tower also has guide blades (7, 8) which rotate it to bring the turbine into the wind. The generaor mechanism is contained inside the space within the tower and is thus protected against the weather. The stiffened construction enables the generator to run even at high wind speeds.
