Patent DE-2401811-A1 (DE)
Title: Flow velocity pickup for electrically insulating liquid - is capacitor consisting of insulating tube with two metal electrodes
Inventor: FETT THEO
IPC: G01F1/64
Filed: 1974-01-12
Abstract: Two pole pieces are placed at the sides of a rectangular tube and are connected by two transversal yokes carrying coils, with both coils connected in series; the capacitor displacement current and opposite direction currents in the leads flow through the magnetic circuit consisting of the pole pieces and yokes. Instead of the two coils a pair of magnetically sensitive indicators, such as Hall generators and field plates may be inserted into air gaps in the yokes. The H.F. voltage applied to the electrodes is modulated several times; it may be amplitude modulated twice. The pick up signal is amplified by a system consisting of selective amplifiers tuned to the modulation and H.F. carrier frequencies.

Title: Valve metal, esp. tantalum, sinter bodies - for electrical condensers, with no differences in density or thickness
Inventor: BUB HUBERTUS
IPC: H01G9/052
Filed: 1974-01-26
Abstract: Valve metal sinter bodies, esp. of Ta, for electrical condensers, are manufactured by mixing the powdered valve metal with a film-forming organic binder dissolved or dispersed in an organic solvent or water in such amts. that a pourable mass is obtained which is cast from a casting mould and the solvent evaporated so as to leave a cohesive and workable sheet. This sheet is then compressed in a cylindrical loom and after removal of residual solvent and binder, the sheet or a portion thereof is mechanically strengthened by a sintering process until it is possible to weld an anode connecting wire thereto in the presence or absence of a protecting gas atmos. The sinter body is then subjected to the final sintering process. Differences in density of the sinter body are obviated, thus improving the electrical props. e.g. residual current and therewith tan.

Title: Masonry shaft especially for waste water - has transportable shaft sections provided on site with connecting tubes
Inventor: SPORKENBACH GUSTAV ADOLF
IPC: E02D29/12
Filed: 1974-02-27
Abstract: The vertical shaft for waste water is built from transportable shaft sections which are built up from individual hollow bricks. On site the shaft structure is provided with apertures for accommodating connecting pipes. After these pipes have been fitted, the cavities in the bricks are filled. The shaft is built from specially shaped bricks, so that a circular shaft can be built, and the bricks radial joining faces have pockets for mortar. These hollow bricks with internal and external curved surfaces have parallel horizontal surfaces. The bricks are joined so that, in addition to the single cavity within a brick, cavities are also formed by the joining ribs. Bricks are joined in the factory to form a lightweight shaft section. These sections are transported to the site and the filling of the hollow bricks adds strength to the shaft and seals the connecting pipes into the shaft walls.
Patent DE-2411397-A1 (DE)
Title: Band drive for long lengths of photographic material - with precautions against damaging material when end of length runs free
Inventor: LAAR ERWIN
IPC: G03D3/13
Filed: 1974-03-09
Abstract: The friction rollers, moving at equal speeds, carry the material into and out of the processing bath. The pulley block guarantees the supply to the input roller. While the pulley block is in the upper position the passage between the final two input rollers is farily straight. This helps the free final end of the material to pass undamaged into the bath. The pulley block leave the upper position only while fresh lengths are engaged. For this, part of the conveyor band must be slackened by bringing into use a roller running at twice the speed of the friction rollers, causing the pulley block to descend and provide a reserve supply to the input pulley for a brief time.

Title: Ceramic dental prosthesis implant anchor - has implant chemically treated to leave pores for bone to interact and bond with
Inventor: KIRSCHNER HORST PROF DR MED
IPC: A61F2/00
Filed: 1974-04-20
Abstract: The implant consists of an inner, metallic-alloy core glued inside a porous ceramic mantle.

Inventor: BROECKER FRANZ JOSEF DIPL CHEM
IPC: C10G25/00
Filed: 1974-10-08
Abstract: Removal of S cpds. from gaseous or liquid hydrocarbons by contact with solid absorbents at 15-100 degrees C, derived from cpds. of formula Me2+6 Me3+2 (OH)16CO3.4H2O, by calcination and subsequent reduction in hydrogen, and in which Me2+ is Fe, Cu, Co or Ni and Me3+ is Al or Cr. Used for treatment of fractions with upper boiling limit up to 250 degrees C, e.g. refinery gases, liquid gases (e.g. propane and butane), petrol fractions and esp. kerosene fractions.

Title: Mixed barium-strontium-calcium oxide cathode coating material - contg. much less barium and less strontium oxide, reducing volatility
Inventor: KAZMAN YAKOW AWRAAMOWITSCH
IPC: H01J19/06
Filed: 1975-01-14
Abstract: The cathode oxide coating material contains 1-20 mole % BaO, 30-50 mole % SrO and 40-65 mole % CaO. The coated anodes are used e.g. in amplifier and transmitting tubes. Volatilisation of the oxide coating material is greatly reduced, whilst a high emissivity is retained, i.e. a low work function is ensured, by the use of more CaO, much less BaO and less SrO than usual. The volatility is 0.08-0.2 units at 1050K, i.e. 5-12 times less than usual, whilst the work function remains at 1.50-1.65 eV. The drop in emission is only 20-35% in 5000 h operation (cf. ca 50% for the usual material contg. equimolar amts. of BaO and SrO and up to 13 mole % CaO).

Title: Coal dust low-temp carbonization - by flue gases from boiler and cyclone separating semicoke for boiler firing
Inventor: SAKALUS EUGENIUSZ DR ING
IPC: C10B49/08
Filed: 1975-04-16
Abstract: In a low-temp carbonization process for hard or brown coal, the raw material is pulverized coal with a size consist similar to that used in pulverized coal fired boilers. The coal dust is mixed with hot flue gases which turn it instantly into suspended semicoke particles. These are separated from the gases in a cyclone and passed by a carrier gas to the burner of a boiler furnace. The mixture of low-temperature gas and flue gases is passed through a cooler where the condensed products are collected for the recovery of carbon derivatives. The gas is desulphurized and fed to the same burners as the semicoke. This saves the expense of the erection of low-temperature carbonization ovens and the environmental pollution caused by them. The system can be applied to new as well as to existing steam boiler installations. The semicoke cooling plant is saved, the coal by-products are recovered and the flue gases are freed from sulphur prior to emission into the atmosphere.
