Patent DE-3818293-A1 (DE)
Inventor: JAKOBSON GERALD DIPL CHEM DR
IPC: C09D7/47
Filed: 1988-05-30
Abstract: The present invention relates to a process for the preparation of nonionic surfactants from fatty acid alkyl esters, mono- or polyhydroxy fatty acid alkyl esters with C6-C22 in the fatty acid component and C1-C4 in the ester component, which are reacted in alkaline medium with one or more isopropylidene derivatives of a polyglycerol at temperatures of 140-220 DEG C and under a vacuum of 950-5 mbar. The resulting C1-C4-alcohol is removed by distillation, and the subsequently purified reaction product is hydrolysed by cleaving at least one isopropylidene group of the reaction product at 20 to 100 DEG C and under atmospheric, subatmospheric or superatmospheric pressure by acid hydrolysis. 
<??>The invention also relates to the use of the surfactant and to skin-care or cosmetic preparations and paints as well as wood preservatives using the nonionic surfactant.

Title: Electronic circuit for the parallel AC network operation of renewable energy
Inventor: RIEDER JOACHIM
IPC: H02J5/00
Filed: 1988-06-29
Abstract: Although the energy supply in industrialised countries is currently provided by fossil, atomic and hydroelectric primary energy, other energy sources are being sought on environmental grounds. At present, these are wind power systems and photovoltaic cells. With small wind systems it is difficult to operate them in parallel with the grid, and with photoelectricity it is almost impossible. There are admittedly a small number of systems which are operated in parallel with the grid, but in order for them to be able to work economically viably, they must have a minimum of 5 kW. This large power capacity makes such systems, despite their economical operation, unaffordable for the private user. Progress in renewable energy is, however, achievable only if such a system is also economical for the private operator. The electronic circuit described in the Patent Application allows the construction of systems with a power of 100 watts or more and would, at current prices for silicon cells, cost only approximately 5000 DM for 1 kW. Such a system operates completely without maintenance and suffers no wear. Since the electronic controller uses DC to generate the electrical power fed into the grid, and the DC voltage may fluctuate between 30 and 310 volts, no particular demands are placed on the electricity generator. It is an easy matter to convert AC, as produced in cheap dynamic generators, into DC... Original abstract incomplete.

Title: Method and device for dividing into portions and pouring out fibrous materials, especially sauerkraut
Inventor: HENGSTENBERG ECKART
IPC: B65B25/04
Filed: 1988-07-09
Abstract: Known methods for pouring out sauerkraut, which is initially mixed with brine, do not provide any guarantee that a specific weight of the dewatered cabbage will be precisely observed while the method is being followed. According to the invention, it is proposed to provide screening walls in the form of moving screening belts, between which the increasingly dewatered strand of the cabbage components is formed and can then be severed to form portions. The new method and a corresponding device are used for dividing sauerkraut into portions. <IMAGE>

Patent DE-3833775-A1 (DE)
IPC: B01F3/18
Filed: 1988-10-05
Abstract: In a process and installation for analysing and homogenizing bulk materials, the flows of materials to be homogenized are analysed before homogenization with respect to their material content and deposited in function of their flow rate. The flows are concentrated in order to obtain maximal masses or quantities for analysis and the mean and standard deviation are calculated in order to determine the long-term variations in the quantity of raw or processed bulk materials corresponding to a given time-interval. Homogenization is carried out in an oval reservoir in which the charging device is a spreader which can be pivoted back and forth and raised and lowered, and the reclaiming device is a continuous system which removes the material transversally to the longitudinal axis of the piled material, conveys it from the outside to the inside and unloads it inside the reservoir onto a belt conveyor located below the base of the piled material, which serves as a discharging conveyor.

Abstract: The container securing system for shipment by sea consists of a floating balloon (10) which is folded together, is inflatable and consists of two chambers (K1 and K2). The floating balloon (10) is attached by means of a net (30) which is located on its upper side and is connected to the container roof (1) or to the respective container by means of the four iron profile parts (2) mounted on the container roof (1). A floating buoy (20), which is likewise inflatable and is fitted with a transmitter, is attached on the net (30) centrally by means of a line (33). A compressed-air bottle (5) located in the container (1) and the closure (6) are opened by a rip cord (7) attached to the ship's deck if the container (1) is lost. As a result, the chamber (K1) of the floating balloon (10) connected to the compressed-air bottle (5) is inflated. By means of the inflation of the chamber (K1), the plastic spring (41) mounted on the bottom of the hard plastic plate (11) located in the chamber (K1) is released. As a result, the propellant (40) located above the plastic spring is ignited and the chamber (K2) of the floating balloon (10) is filled with gas. This operation actuates the rip cord which, in turn, opens the compressed-air bottle in the floating buoy (20) as a result of which the floating buoy (20) is likewise inflated and put into action. <IMAGE>

Filed: 1989-09-02
Abstract: A planar semiconductor component is useful as a metal-dielectric semiconductor arrangement (MOS arrangement). The metallic layer (4) is sufficiently thin, at least in regions of the component in which large potential differences arise, that in the event of an electrical breakdown between the metallic layer (4) and the semiconductor (1) below the dielectric breakdown field strength (EBmax), the metal in the metallic layer (4) melts and vaporizes.
