Patent DE-3533806-A1 (DE)
Title: Process for reducing the surface tension of aqueous solutions
Inventor: STUEHLER HERBERT DR
IPC: C09K23/00
Filed: 1985-09-21
Abstract: In the new process, certain reaction products of polyglycerol (polyglycerin) and fatty acid are used to lower the surface tension of aqueous solutions of organic or inorganic salts. The reaction products are ones which are obtained if a polyglycerol having a hydroxyl number (hydroxyl index) from 860 to 800 is esterified under acid catalysis with a fatty acid in a molar ratio of 1:0.3 to 0.7 until a hydroxyl number from 770 to 680 and an acid number (acid index) of at most 0.7 are reached. The proposed esterification products are added to the solutions (compositions) to be treated in an effective amount which is generally an amount from 0.005 to 10 % by weight, based on the weight of the solution (composition).

Patent DE-3605267-A1 (DE)
Title: Catalyst
Inventor: FRITSCH PETER
IPC: B01J35/04
Filed: 1986-02-19
Abstract: In domestic and commercial furnaces which are operated with solid fuels (wood, coal, paper, sawdust, wastes, etc), considerable amounts of pollutants arise in the form of exhaust gases and soot which are given off into the air via the stack. This air contamination, smoke and soot pollution is, moreover, a further waste of energy. These considerable defects can be rectified with the installation of an "electric tube catalyst" (termed ETC below). The soot and the pollutant-containing exhaust gases are completely burnt in the ETC, thus the energy contained in the fuel is utilised to the maximum and the heating capacity and the economic efficiency of the plant are considerably increased. The ETC is versatile in use since it operates autonomously, independently of the actual furnace and its heat delivery. The ETC can be installed into any individual furnace as also at a stack and combust all of its exhaust gases. Heat is recovered via a heat exchanger. The completely burnt and soot-free exhaust gases can thus be cooled down to a very low residual temperature. The capacity of the ETC is matched to the actual requirement, and the ETC is monitored, by electronic control equipment. <IMAGE>

Title: Catalytic two-stage coal hydrogenation and hydroconversion process
Inventor: MACARTHUR JAMES B
IPC: C10G1/00
Filed: 1986-04-21
Abstract: The invention relates to a process for the two-stage catalytic hydrogenation and liquefaction of coal for obtaining increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal is slurried with a liquid solvent derived from the process and fed at a temperature below about 343.3 DEG C (650 DEG F) into a first stage of a catalytic reaction zone which is operated under conditions which promote a controlled rate of the liquefaction of the coal, while at the same time the recycled hydrocarbon oils are hydrogenated under conditions which favour hydrogenation reactions. The reactor of the first stage is held at a temperature of 343.3 to 426.7 DEG C (650 to 800 DEG F), at a hydrogen partial pressure of 70.3 to 281 kg/cm<2> (1000 to 4000 psig) and at 10 to 60 lb/hr/ft<3> space velocity. The partially hydrogenated material from the reaction zone of the first stage is passed directly to the second stage of the catalytic reaction zone, which is held at a temperature of 398.9 to 468.6 DEG C (750 to 875 DEG F) for further hydrogenation and thermal hydroconversion reactions. By means of this process, the coal feedstock is successively catalytically hydrogenated and hydroconverted under select conditions, which... as a result to markedly increased yields of desired low-boiling...

Title: Door-lock heating
Inventor: RUDNICK WILFRIED
IPC: E05B17/00
Filed: 1986-11-20
Abstract: Technical problem of the invention: The object to the invented system is to de-ice a frozen door lock. This operation has hitherto been carried out by a stick heated from outside, which has been introduced into the frozen car-door locks, or else the lock has been heated with a lighter. Another alternative is the de-icing spray. Solution of the problem: By means of an IR minitransmitter installed in the key, the car driver always has the possibility of acting electronically from outside on the heating which surrounds the door lock. There are two methods for putting the heating out of operation during the summer months:   1. by means of a switch which is attached to the dashboard of the vehicle or 2. by means of a thermostat which, in winter, always automatically keeps the heating ready for operation. By touching the key head three times, the key transmits an IR signal which is intercepted by the receiver inside the car door.   <IMAGE>

Title: Circuit arrangement for limiting the current in a timed DC voltage converter
Inventor: LOESEL WALTER
IPC: H03K17/30
Filed: 1987-03-27
Abstract: The described circuit arrangement for limiting the current is intended for a timed d.c. current converter in which there is voltage separation between the primary and the secondary sides and in which the switching-on times of a switching transistor in the primary circuit are changed by a pulse width modulator. By changing the switching-on times of the switching transistor, the output voltage is regulated to its required value and the current in the primary circuit is kept below a critical value. In order to limit the current in the primary circuit, the decreasing voltage across a measurement resistance is compared with a threshold voltage. If in such a d.c. voltage converter the switching-on times of the switching transistor must continuously be shortened because of an increasing load at the output and consequently an increasing current in the primary circuit, then the voltage at the output decreases with increasing output current. In order to obtain a limitation of the output current even in this case, the threshold voltage is then reduced by means of a voltage-separating component (0) when the output voltage (Ua) drops below a predetermined fraction of its required value. <IMAGE>

Inventor: WEISSHAUPT BRUNO
IPC: H03K17/95
Filed: 1987-05-05
Abstract: A proximity switch has an oscillator dimensioned in such a way that its output characteristic is extended, so as to be able to fix plural switching distances over the entire possible range which are as far apart as possible. This can be achieved by an oscillator (30) with an oscillator coil (32) having a centre tap (33) and an end tap (34) giving two outputs (A1, A2) providing respective switching signals at different switching distances (S1, S2). A single switching point or both switching points can be varied, in order to obtain random window functions. One output (A1) can be a.c. coupled while the other output (A2) is d.c. coupled. <IMAGE>

Abstract: In a known plastic closure cap, its edge part is formed, as security ring, integrally with a screw cap via connection webs, the latter extending approximately radially in the transition from the outside circumference of the screw cap to the top circumference of the security ring. As a result of this radial arrangement of the connection webs, there is a risk that sharp tear-off ends of the connection webs remain on the outside circumference of the screw cap after it is unscrewed for the first time, which results in a risk of injury to the hands of the users of this closure cap. The risk of injury is to be ruled out completely by the new closure cap when it is unscrewed. In a closure cap with a tamper-proof security ring (3), which is constructed integrally with the screw cap (5) via connection webs (4), said connection webs (4) are sprayed onto the screw cap (5) in a lower position relative to the lower edge (15) of said screw cap. As a result, when the closure cap is unscrewed from a container for the first time, the tear-off ends of the connection webs (4) remain completely inside the lower edge (15) of the screw cap so that no tear-off ends projecting axially or radially over said lower edge result. <IMAGE>

Title: Method, with the associated devices, for cooling or heating liquids or gases using the Peltier effect
Inventor: REENTS HEINRICH PROF DR ING
IPC: B67D3/00
Filed: 1987-11-20
Abstract: The taste of drinks is determined decisively by the temperature. The consumer thus wants a "cool beer". At the same time, for reasons of keeping quality, the temperature level may only vary within strictly predetermined limits. In addition to the absolute temperature level, the relative temperature, the temperature difference, also plays a crucial role. Furthermore, the cooling process, i.e. the temporal cooling gradient, is crucial for the state of liquids or gases. These requirements presuppose mobile cooling systems which guarantee reliable cooling until shortly before removal/use. The mobile operation requires extreme mechanical strength, small construction sizes, low environmental pollution and great economy with simultaneously low energy consumption. At the same time, the cooling unit is in this case also to assume heating functions if required. These requirements are met by the method, with the associated devices, presented in this invention. The method with the associated devices is based on the use of thermo-electric cooling. As a result of the extreme adaptation of the cooling system to the container, compact construction sizes are achieved. Possibilities for application lie in drink preparation in the form of the cooling bar, preservation of stored blood in the area of medical technology, drink transport and drink extraction. Further possibilities for application lie in preparation and ... Original abstract incomplete.
