Title: Intake string for a reciprocating internal-combustion engine
Inventor: ADAMIS PANAGIOTIS DR ING
IPC: F02B27/02
Filed: 1987-12-18
Abstract: What is described is an intake system for a reciprocating internal-combustion engine for vehicles, especially for passenger motor vehicles, which has intake pipes which lead to the individual cylinders of the internal-combustion engine and which are each divided into at least two intake strings (3, 4) connectable in succession by shut-off members (6, 8) as a function of the engine speed. In order, under full load, to increase the torque of the internal-combustion engine within wide engine-speed ranges by utilising gas-oscillation phenomena in the intake pipe, the shut-off member (6) of the first intake string (3) connected alone at low engine speeds is to be designed as a non-return flap which can be loaded in the opening direction, counter to a return spring (7), by the working medium flowing through the intake string. In order, particularly at the lowest engine speeds, to prevent the cylinder charge from flowing back through the still open intake valve towards the end of the inlet stroke, there is to be provided an actuating device which releases the non-return flap (6) in a first lower engine-speed range, so that it is subjected only to the effect of the return spring (7), and which keeps the non-return flap constantly in the opening position in a second upper engine-speed range. <IMAGE>
Patent DE-3801698-A1 (DE)
Title: Counting system for moving objects
Inventor: SLIWA STANISLAS
IPC: G06M7/00
Filed: 1988-01-21
Abstract: The counting system has on the one hand at least one emission/reception cell which outputs a pulsating beam which is narrow enough to be able to distinguish between two objects which have been brought together. On the other hand, the system has an electronic counting circuit which distinguishes between spurious pulses and correct signals, that is to say such signals as are produced by direct reflection when objects pass through. After each counting event a non-detection period is switched on which is long enough to avoid double counting of objects which move slowly or have a plurality of surfaces which reflect perpendicularly to the beam. The system preferably has two cells which are arranged next to each other in the through-passage direction. They are modulated with different frequencies so that the counting circuit can distinguish between their signals and therefore fix the direction of movement of the objects. The system makes it possible very reliably to count the number of passengers entering or leaving a bus and consequently, for example, to manage a transport system. <IMAGE>

Patent DE-3830038-A1 (DE)
Title: Burner and method for its operation
Inventor: KLUG KARL HERBERT DIPL ING
IPC: F23D14/66
Filed: 1988-09-03
Abstract: The fuel is introduced into the flame in stages, it being possible for the flame gases to cool down as they travel from one stage to the next. In addition, the fuel is so intensely heated downstream of the first stage that self-carburisation arises. Consequently, the flame receives improved radiation properties, with the result that its temperature decreases. Finally, inert gas is sucked into the flame as cooling gas. A combustion with greatly reduced Nox formation results.

Title: Process for the production of a spun web made from thermoplastic
Inventor: REIFENHAEUSER HANS
IPC: D04H3/16
Filed: 1988-10-19
Abstract: Process for the production of a spun web made from thermoplastic. A heated spinnable initial mixture which is under increased pressure is opened up into a group of monofilaments by means of spinnerets. The group of monofilaments is treated with cooling and/or drafting air and deposited on a conveyor band to form a non-woven spun web. A further treatment, for example for the purpose of binding a pattern, can follow. The work is carried out with a foamable initial mixture which has a temperature sufficient for foaming and which, until it emerges from the spinnerets, is maintained at a pressure which suppresses foaming. The initial mixture is foamed by expansion in the spinnerets and/or when it emerges from the spinnerets.

Title: Method for program design for washing machines and device for carrying out the method
Inventor: OTT GUENTER ING GRAD
IPC: D06F33/36
Filed: 1989-02-01
Abstract: For the purpose of optimising the washing cycle, a laundry-drum reversing mode adapted to the lye temperature and having a different relative switch-on period of the drive motor is to be executed. A known method, whilst maintaining the conventional average relative switch-on period in the high-temperature phase of the washing lye, increases the said switch-on period by a specific value and at the same time decreases it again by the same amount in the washing-lye heating phase. In the method according to the invention, the relative switch-on period is increased to a permissible maximum even before the start of heating, during the inflow of water, and the washing agents are thereby dissolved more effectively, is reduced in a plurality of steps during the lye-heating phase and at the end, in the so-called rewashing time, is again increased briefly to the maximum or to a value lying somewhat below this. The method serves for optimising the washing cycle in domestic washing machines and, at the same time, for minimising the size of their drive motors. <IMAGE>
