Title: Steel tubes with longitudinal welded seam - using oxygen and steam blast to remove slag from internal surface of weld
Inventor: SCHMITZ ALFRED
IPC: B23K7/08
Filed: 1974-12-05
Abstract: Device for mfg. steel tubes with longitudinal welded seams from very long strip, at least the edges of the strip being heated to the pressure welding temp. The device consists of a funnel or pair of forming rolls to bend the strip into a slit tube, followed by a pair of pressure rolls used to make the weld and then by rolls for reducing the cross-section of the tube and/or obtaining the required dimensional tolerances; and with >=1 air/oxygen jets directed onto the welded seam. The air/oxygen jet(s) or one or more additional air/oxygen jets are directed onto the internal welded seam both through the slit and down the welded tube through the pressure rolls, the jets being directly supplied by separate pipes of the frame of the welding machine, both the jets and pipes being surrounded by a cooling jacket from which water is sprayed down the welded tube. Used in the Fretz-Moon forge welding process. Produces a smooth bore free from slag and scale so only light pickling is required, e.g. prior to cold drawing.

Title: Stator for a multistage radial compressor - has bladed diffuser held on fixed blading stage supports connected together
Inventor: KORENBLIT ISYA YAKOWLEWITSCH
IPC: F04D29/42
Filed: 1974-12-07
Abstract: The stator can be used successfully for high pressure multistage radial compressors with bladeed diffusors, which are widely used in the gas and chemical industries. The fixed blade supports of all stages are connected to each other in order to reduce the quantity of metal used and in order to reduce gap losses between stator sections. The fixed blade support accommodates also bladed diffusor and return flow section which is firmly held on the fixed blade support of the following stage. The bladed diffusor (7) of each stage is connected to the fixed blade carrier (6) and return flow section (8) so that their connection region is located on a diameter which is smaller than the maximum diameter of the flow section. This arrangement is produced relatively cheaply.

Title: Electro servo operated driving mirror - has plastic, axially slotted drive nut as torque limited drive
Inventor: SEBALD WALTER
IPC: B60R1/072
Filed: 1975-03-03
Abstract: The external driving mirror is set at the selected angles by a servo driven shaft (2) from an electric motor. The shaft is coupled to the mirror by a special threaded nut (4). The nut is moulded from a thermoplastic and has axial slots (6) extending from either end. This provides a weakened structure so that when the torque on the drive shaft exceeds a set value the nut is splayed out to disengage the threads, and allow the drive to slip. Alternatively, only the top and bottom edges of the nut are threaded leaving the middle section clear of the thread.

Title: Achieving white discharges on cellulosic textiles - by using etching pastes contg. alkaline cpds. and press. steaming
Inventor: FEESS ERICH DR
IPC: D06P5/15
Filed: 1975-06-05
Abstract: White discharges on natural or regenerated cellulose fibre textiles, pre-dyed or printed with azo dyes, are achieved by using etching pastes contg. alkaline acting substances and developing by a treatment with press. steam of >0.5 (0.5-2.5) esp. 0.5-1.5 atmos. over-press., pref. for 3-20 (6-10) min. Process can be used for achieving white discharges on padded, pre-dyed or printed cellulosic fabrics by printing with etching agent-free alkaline printing pastes and press.-steaming. Use of press. steam 0.5 atmos. over-press, increases cellulose reduction potential in the presence of alkalies so highly that azo dyes can be destroyed on fibre without addn. of reducing agents. Etching agent-free printing pastes can be used, resulting in unlimited stability of printing colours and storage stability of printed materials before steaming.

Title: Large storage tank - of prefabricated fibre reinforced plastic units with anchor strips on bottom and roof internal ribs
Inventor: VOSS ADOLF DIPL ING
IPC: B65D90/02
Filed: 1975-06-14
Abstract: A storage tank for large quantities of fuel oil can be assembled on site from plane bottom and roof parts, concave sides and spherical corners, all made of glass fibre reinforced plastics. The bottom and roof panels have parallel rbs in an inward direction, of a size similar to the flanges of the side panels, which act as the anchors for vertical tie rods. Such a tank can withstand internal pressures which may be caused by a temp. rise of an almost empty tank or by overfilling. A test pressure of 1.5 bars as required in certain countries is well within the capacity.

Title: Concrete road surface elastic joint - with profiled units engaging slab depressions and close fitting horizontal faces
Inventor: FELDMANN ECKARD DIPL ING
IPC: E01C11/10
Filed: 1975-09-19
Abstract: The consolidation for road or pedestrian paths of concrete with elastic joints is as in the parent patent which uses force-locked connection of the joint construction material with the slabs. This prevents relative slab displacement vertically to the centre planes of the slabs, but is technically feasible only where there are dry surfaces and predetermined min. temps. Instead one or more shaped-section units (4) engage in one or more depressions in the slabs. The virtually horizontal surfaces of shaped-section units and depressions lie so that they fit closely together.

Title: Radio telephone calling channel selection method - uses time integration of successive signals for choice of frequency
Inventor: BRAAK DIRK JOHAN DIPL ING
IPC: H04W48/16
Filed: 1975-10-21
Abstract: The radio telephone channel selection system for fixed and mobile stations enables the mobile equipment to select the the most appropriate calling frequency from a number of possible frequencies, depending on the average field strength of the received frequencies. For a number of successive cycles of each calling channel, the received field strength time integral is developed in a time-slop of length (t). The time integral values of all cycles are added together. The number of cycles (n) and the time-slot length are so arranged that the measured time n x t of the calling channel frequency is of the same order of magnitude as the minimum time required for averaging the received field strength.

Title: Dyed polyester-cellulose fixings process - using roughened heated surface to prevent a frosted effect
Inventor: KOECHLING GERHARD
IPC: D06B19/00
Filed: 1976-01-14
Abstract: A frosting effect is prevented from being created during the finishing of dyed fibre material composed of polyester and polyester-cellulose mixts. During the thermal fixing stage for the dyed material, the thermal effect is applied by heating roughened surfaces or surfaces of a temperature-resistant rough material. The process ensures that all the fibres absorb the dye and each dyed fibre is fixed, without incurring fibre hardening or other effects which would alter the fabric handle.

Title: Removal of hydrogen in carbon dioxide gases for urea synthesis - by leading the impure gas with oxygen over precious metal catalyst
Inventor: OCHIAI MASAO
IPC: C01B32/50
Filed: 1976-02-03
Abstract: carbon dioxide gases used as starting material in the urea synthesis from NH3 and CO2, are mixed with O2 in the presence of a catalyst of Ru,Rh,Pd and/or Pt to react the H2-gas to form H2O. The treated CO2-gas may then be re-used as starting material in the synthesis. The process removed H2 from the impure gas and obviates the danger of explosions without undue influence on the urea synthesis.
