Patent DE-4311829-A1 (DE)
Title: Refrigerator and/or freezer
Inventor: GUENTHER EBERHARD DIPL ING
IPC: F25D11/00
Filed: 1993-04-14
Abstract: The invention relates to refrigerators and/or freezers which are used in the household, in particular to those refrigerators and/or freezers which have been advertised as "eco appliances". In this connection, the invention proposes to adapt the outer shape of the refrigerator and/or freezer to a cylindrical basic body with a basic surface from circular to elliptical and oval and to use the inner wall and outer wall for main refrigerating components of the circuit process, namely evaporator and condenser. The advantage of the invention is the simplified construction which furthermore can be utilised very well for corner and niche construction. A further major advantage is the optimum design of the ratio of internal volume to heat incidence surface and, associated with this, a relatively low energy consumption.

Patent DE-4324242-A1 (DE)
Inventor: STEINBRECHER FRIEDRICH RUDOLF
IPC: E04D13/03
Filed: 1993-07-20
Abstract: A skylight strip (1) for a roof (2) of an arcuate cross-section is arranged transversely with respect to the roof ridge and is formed by skylight panels (4) held in a frame (3). Said skylight strip (1) runs over the entire extent of the roof width or of the roof arc, with the result that its short sides or ends (5) help to form, or continue, the border (6) of the roof, as it were. The skylight panels (4) are configured, in the direction of the short dimension, that is to say in the direction of the roof ridge, with straight surface lines, that is to say they are not of an arched configuration, and are held, on the long borders, in a sealing clamping fit, with the result that heat movements are possible. A cutout, enclosed on all sides, within a roof, can thus be avoided because such a skylight strip (1) can be fitted between the borders of individual roof elements (13) in such a manner as to connect and span the same. <IMAGE>
Patent DE-4324955-A1 (DE)
Title: Single stroke internal combustion engine with piston valve timing and turbine connected on the output side, for various solid explosives
Inventor: KUHN HELMUT
IPC: F02B47/02
Filed: 1993-07-24
Abstract: Compared to the prior art, that is to the combustion or firing of surplus ammunition stocks in combustion chambers, this technology for driving an engine for the generation of electricity at times of peak consumption offers the advantage that the energy contained in the grenades and cartridges is virtually fully utilised. The object is to optimise the efficiency of the technology described in the Imperial Patent Specification No. 305967 by reducing the working principle to one stroke. Following the power stroke the exhaust gas is admitted into the crankcase by way of the piston valve. In the crankcase, water from the cooling circuit is injected in order to enrich the exhaust gas with water vapour and thus also to increase the efficiency of the turbine connected on the output side. The engine should be built in at least a two-cylinder version. This technology is outstandingly suited to driving generators for the generation of electricity at peak consumption times. Also because of the maintenance and cleaning intervals continually necessary.
Patent DE-4327724-A1 (DE)

Inventor: SONDERMANN KARL DR ING
IPC: B22D11/04
Filed: 1993-08-18

Patent DE-4329643-A1 (DE)
Title: Receiver for concentrated solar radiation
Inventor: HESSENIUS THEO DIPL ING
IPC: F24S20/20
Filed: 1993-09-02
Abstract: A receiver for concentrated solar radiation for carrying out energy-absorbing chemical-physical processes with the participation of a molten mass is described. The applications preferably lie in the temperature range above 1000 DEG C. If poisonous or environmentally hazardous gases are produced in chemical or physical processes, they must not get into the atmosphere. In the high-temperature range, however, there are no radiation-transparent materials available which withstand the practical conditions. The invention solves the problem in that the reaction chamber (6) is separated from the receiver chamber (2) by an internal wall (5) plunging into the molten mass (3). It is thus not necessary for the inlet opening for the solar radiation (1) to be provided with a transparent window. The gases produced during the reaction can be carried away out of the reaction chamber (6). The energy transport into the reaction chamber (6) is effected via thermal conduction and free convection in the molten mass (3). Preferred applications lie in the area of carbothermic reductions. <IMAGE>

Patent DE-4413480-A1 (DE)
Title: Engine which uses hydraulics instead of combustion
IPC: F02B75/32
Filed: 1994-04-19
Abstract: Two designs of engine are proposed. The first engine consists of a block with hydraulic cylinders of unlimited number attached. The cylinders can be in a V, rows or as a boxer. Injection is by any appropriate type. A suitable electronic processor controls the injection sequence. Speed control is also electronic. Batteries are used for starting and are recharged by an accessory alternator. Hydraulic fluid is the injected medium.

Title: Activated sludge treatment of waste water in single tank
Inventor: BALLNUS WILHELM
IPC: C02F3/30
Filed: 1994-07-09
Abstract: Biological purificn. of waste water for removal of C, N and phosphate using activated sludge is carried out in a single, undivided sludge tank in which regulated and periodically repeated, but not simultaneous oxidic, anoxic and anaerobic process stages are effected. The process stages are regulated by parameters including turbidity of the clarified water fraction of the water and sludge mixt. in the tank. For denitrification of nitrate, immediately after completion of the oxidic phase and cessation of aeration, a C-contg. organic substrate (A), or its salt, is added to the tank until redissolution of phosphate starts.  (A) is pref. added until an increase in dissolved phosphate content is detected, indicating the end of the anoxic phase and complete denitrification. The same monitor is used to follow phosphate redissolution in the subsequent anaerobic phase.

Patent DE-4435849-A1 (DE)
Inventor: MANN EGON
IPC: F16H1/46
Filed: 1994-10-07
Abstract: An elevator drive has a driving engine, a brake (6) and a two-stage planetary gear (9). Both stages (8, 10) of the planetary gear have helical toothing. The sun wheel (15) of the second planetary gear stage (10) is floatingly mounted in a hub-carrier (17) or hub (21, 23) on a bearing (16) that absorbs axial and radial forces. This arrangement reduces the axial overall length. The sun wheels (7, 15) of the planetary gear stages (8, 10) may adapt to load conditions. The helical toothing of the planetary (9) prevents low-frequency vibrations which may propagate up to the lift cabin, specially when they are transmitted over long cables, and could be perceived there as a disturbing humming noise.
