Patent DE-2837835-A1 (DE)
Title: Cartridges for reinforcing or sealing structure, anchoring bolts etc. - comprise macro-capsules contg. component(s) of curable polymer system which fracture under pressure to form flake-like fragments
Inventor: SEEMANN RONALD W
IPC: F16B13/14
Filed: 1978-08-28
Abstract: A sealing cartridge for reinforcing or sealing solid structures, anchoring bolts etc. is cylindrical and includes a cylindrical array of relatively non-mobile pressure fragmentable non-friable macrocapsules. These macrocapsules contain a multi-part curable polymer system, having two or more parts which when mixed together form a polymer or resin of higher molecular wt. The macrocapsules have a major dimension from 4.75mm to about 95% of the dia, of the cylindrical array, and can form flake like fragments from their walls when they fragment under pressure and release their contents. The cartridge is positioned in a hole in the solid structure and a bolt is forced into the cartridge to break the macrocapsules. The polymer system is then cured to anchor the bolt. When reinforcing or sealing the solid structure, the bolt is removed from the hole before the polymer is completely cured. It is relatively easy to break the macrocapsules and commence curing.

Title: Regeneration of spent catalysts - by extn. of reaction prods. via liq. gas, esp. when catalyst has been used for hydrogenation of fats
Inventor: ABEL HEINZ
IPC: B01J23/90
Filed: 1978-12-08
Abstract: The catalysts are used in (de)hydrogenation-, oxidn.-, and polymerisation- processes; and the extn. medium is a fluid consisting of a gas in a supercritical state. The fluid is then pref. expanded to below its critical pressure so it becomes sepd. from the extracted reaction prods.; it is next recompressed and returned to the extn. process. The catalyst consists esp. of Ni or Cu, and is used for the hydrogenation of fats, esp. where the catalyst is located on a carrier made of metal oxide, e.g. Al2O3, MgO or SiO2 such as diatomite. The extn. medium is esp. CO2. After removing the main part of the reaction prods., the remainder is pref. removed from the spent catalyst by distn. at 250-400 degrees C in a counter-current of H2 in appts. described e.g. in DT 2403998. When a catalyst appears spent, it still contains a substantial amt. of active material, which may include noble metals. The invention removes reaction prods. so the catalyst may be reclaimed.

Title: Clay moulding mixt. - contains waste paper or similar materials reducing the wt. of baked prods. made from the clay
Inventor: RASBACH HEINZ
IPC: C04B33/13
Filed: 1979-03-14
Abstract: The mixt. consists of pit-wet clay contg. 5-35 wt.%, esp. 15-25 wt.% of paper, cardboard, pulp, or similar materials; and the pref. addn. is waste paper or a similar waste prod. The clay is used in the ceramic industry, e.g. for the mfr. of bricks or plant pots, where water is added to the mixt., which is then moulded, dried and baked. The conventional baked prod. are heavy, and thus involve high transport and storage costs. The invention uses the addn. of paper etc. to the initial mixt. to produce prods. with low wt. and low cost. The invention does not impair the dimension accuracy, surface quality, or strength and hardness of the prods., but substantially reduces their wt.

Title: Foamed plastics articles moulded without cavities with constant mass - by fitting dead spaces in cavities with vents closed by porous foamed plastics members
Inventor: FUNCK HERBERT DR ING
IPC: B29C33/12

Title: Low-cost energy generation - from free falling liquid recycled by evaporation to initial level
Inventor: THAMS HANS
IPC: F03G3/00
Filed: 1979-07-30
Abstract: A liquid is dropped down a pipe to drive a turbine, coupled to a generator for the prodn. of electric power. The liquid is circulated in a closed circuit by being raised to its initial level through evaporation. The energy supply for the evaporation comes from a heat pump which extracts the heat from the earth itself. The pref. liquid gas has a high specific gravity and low specific heat, for example trichlorofluoromethane with a liquid-gas change point at 24 deg.C. The heat pump can be replaced by solar heat collectors. This saves oil, gas and coal and provides energy at low cost. It causes no environmental pollution by exhausts or smoke.

The length of the pre-fabricated hard-foam panels corresponds to the distance between adjacent struts. The hard-foam panels are reinforced and their top edges are covered with cappings.
Patent DE-2936162-A1 (DE)
Inventor: KRAEMER MANFRED DIPL ING
IPC: F02D1/14
Filed: 1979-09-07
Abstract: A control apparatus for internal combustion engines is proposed, in which the adjustment range or the full-load position of a supply quantity adjustment member of the fuel metering apparatus is varied in accordance with the absolute pressure of the aspirated air in the suction tube of the engine in order to attain optimal combustion at the greatest possible torque. The control apparatus (FIG. 1) includes a pneumatic pressure converter and a pneumatic adjustment member. The pneumatic pressure converter, in a first pressure chamber, contains an evacuated diaphragm pressure box exposed to the aspirated air pressure (pL), which acts counter to a second diaphragm pressure box exposed in its interior to atmospheric air pressure (pA) and located in a second pressure chamber connected to a compressed air source. Both pressure boxes are connected via an actuation member supporting a valve member, and the valve member reduces the servo air pressure (pS) to a control air pressure (pSt) which is proportional to the absolute aspirated air pressure (pLK), this control air pressure actuating the diaphragm adjustment member functioning counter to a restoring spring and to atmospheric air pressure.
