Patent DE-4123783-A1 (DE)
Inventor: BURG ANDREAS DIPL ING
IPC: B60T8/00
Filed: 1991-07-18
Abstract: Described is a drive-slip control system in which increase and reduction in pressure are produced by series of pulses. The pulse lengths are selected such that each pulse produces the same change in pressure. The difference between pressure-increase and pressure-reduction pulses is then a measure of the pressure at the wheel brake and can, for instance, be taken into account in an additionally fitted engine-torque governor.

Inventor: POENITZ GERD DIPL ING
IPC: H04M19/04
Filed: 1991-08-09
Abstract: The circuit includes a control (ST) with inputs (4) and outputs (1,2,3). The controller (ST) analyses the incoming call signals on the connection line and generates the sound signals for the electroacoustic transducer (W) driven by an amplifier (T2,T3). The volume of the transducer is adjusted in dependence on the operation of a button (TA) connected to the controller (ST). The sound signal output (T) of the controller (ST) is connected to the base of a transistor (T1). One output (1) of the controller (ST) is directly connected to the emitter. Other outputs (2,3) are connected to the emitter via resistors (R2,R3) of different values and an earthed resistor (R4). The collector of the transistor (T1) is connected via a resistor (p1) to the operating voltage (+U1) and to the amplifier (T2,T3) controlling the transducer. The controller (ST) earths one of the outputs (1,2,3) corresp. to the desired volume, in dependence on the state of the button (TA). ADVANTAGE - Simple, inexpensive and reliable.

Inventor: MAIER WILHELM F
IPC: B01D71/02
Filed: 1993-02-09
Abstract: The invention relates to a poison-resistant catalytically active microporous membrane to be used for heterogeneously catalyzed reactions, which membrane is characterized in that it is permeable to one of the reactants separated by said membrane, and that it is impermeable to the other reactants and the contaminants contained therein, the molecules of all of which are larger in size than the pore size of the membrane, and to a process for carrying out a heterogeneously catalyzed reaction under conditions preventing the catalyst from being poisoned. This membrane allows to conduct three-phase reactions in a new manner, whereby the reaction gas is directly transported to the active sites. <IMAGE>

Title: Washing machine for washing soln. intensive penetration in laundry - comprises unperforated washing drum and hollow body attached to drum with washing soln. entry and discharge openings, for min. amt. of free soln.
Inventor: STOLL MANFRED DIPL ING
IPC: D06F23/02
Filed: 1993-03-27
Abstract: The machine has an unperforated washing drum (1), which is mounted rotatingly in a washing soln. container (3). The drum surface is conical, roof-shaped or spherical and a pump (6) conveys the washing soln. in a circulation system while another pump (7) conveys the used soln. into the drainage system. The outside or the inside of the drum (1) has a hollow body (18), which is fixed to the drum (1) and one end has a soln. entry opening (21) ending in the washing drum interior (9). At the other end, the hollow body (18) includes a discharge opening (23), which lies on or near the drum periphery and leads in the direction of the washing soln. container (3). As a result of the geometry of the hollow body (18), the washing soln. leaves the drum (1) as a result of the centrifugal force during spinning in one rotation direction. During spinning in the other direction, the washing soln. remains in the drum (1) during the acceleration of the drum. ADVANTAGE - The intensive penetration of the washing by the washing soln. is obtd. in spite a min. amt. of free soln. Undesirable foam formation is also eliminated.

Title: The cold motor
Inventor: VAZIRI-ELAHI MORTEZA DR ING
IPC: F01K25/10
Filed: 1993-04-14
Abstract: The invention relates to a drive motor whose exhaust gases are cold and free from substances deleterious to health and the environment. The enormous quantities of poisonous gases which conventional internal combustion engines emit into the atmosphere, and the loss of vital oxygen which is withdrawn from our atmosphere during combustion, as well as the growing enormous quantities of heat have brought our planet to the edge of destruction! According to the invention, use is made here as fuel of liquid nitrogen (N2), which can be obtained cost-effectively in unlimited quantities from the air. It is inexpensive, nonpoisonous and not combustible! The fuel tank is provided as a superinsulated container (vessel) from which the liquid nitrogen is conveyed through a line by means of a pump to a heating element where it evaporates explosively. The heating element can be installed directly in the working chamber of the motor (e.g. like a sparking plug in the cylinder), or else outside it. The cold motor is most suitable for lorries (trucks), buses, private cars (automobiles), water craft etc.
Patent DE-4316936-A1 (DE)
Title: Process for treating gas to be purified in pollutant transfer units and apparatus for carrying out this process
Inventor: STELZER HANS DIETER DIPL ING
IPC: B01D53/84
Filed: 1993-05-21
Abstract: There is a process in which the gas to be purified is present in at least two part-streams 13 each of which is passed to one of the pollutant transfer units 2, 3 and is passed through the first and second pollutant transfer unit 2, 3. It is desired here to improve the pollutant degradation efficiency of the pollutant transfer units by dividing the gas to be purified into part-streams. The process according to the invention achieving this object is characterised in that the second part-stream is passed through the second transfer unit together with the first part-stream leaving the first transfer unit. An increase occurs in the degradation efficiency of the pollutant transfer units in biological exhaust air purification by subdividing the gas to be purified. <IMAGE>

Title: Belt-guiding shoe for belt-grinding machines
Inventor: ZOELLIG GUENTER DR
IPC: B24B21/20
Filed: 1993-05-29
Abstract: The invention relates to the shape of a belt-guiding shoe of a belt-grinding machine used in particular for cam grinding. The aim is to render the removal of material more uniform over the cam width. This is acheived by a slight edge bevel (9) at the outer edges of the belt-guiding shoe (4). The grinding-belt edges projecting beyond the cam surface are applied against this angled-off edge bevel and prevent edge wastage at the cam surface by reduced removal of material at the cam edges. <IMAGE>
