Title: Fuzzy logic based servo controller - has loop input error values received by fuzzy logic circuit to determine corrective action based upon linguistic rules
Inventor: KROGMANN UWE
IPC: G05B13/02
Filed: 1992-12-04
Abstract: An alternative to conventional PID (linear) control of a process is provided by system employing fuzzy logic rules to determine the values to be applied for correction to a non-linear control system . The inputs generated (36,38,52) are received by a fuzzy logic circuit (58) to convert them into linguistic based rule values i.e. very big, big, small, very small etc. A memory (54) stores the defined membership functions for the different ranges of value and a second memory (92) stores the rules. The membership grade values are combined (62,64) and a control output is produced (66). USE/ADVANTAGE - For non-linear process control systems, robots etc. Provides insensitivity to parameter changes.

Title: Softening water used in e.g. dishwashing machine - with controlled magnetic field at water flow directly before ion exchange unit
Inventor: SCHULZE ELFRIEDE
IPC: C02F1/48
Filed: 1993-01-27
Abstract: In softening water, where it passes through an ion exchanger (3) using a suitable material and pref. sodium chloride, it passes through a magnetic field directly before softening. The water pref. passes through a magnetic field which has an intensity which is altered in periods, and the polarity of the magnetic field is reversed in periods at the unit (4) where the magnetic field is applied to the water directly before it enters the ion exchanger (3). USE/ADVANTAGE - The method is partic. for water which is to be used in an appliance, such as a clothes or dish washing machine and the like, to prevent scale build-up. The magnetic field modifies the structure of the lime particles to give a lower salt consumption with savings of about 50%.

The projecting edges are pressed onto the ground, thereby sealing the inner sheeting space. The insulation layer consists of individual panels (4), which are connected by tongue and groove. Alternately, the insulation may be drawn off rolls. The projecting sheeting edge may be weighed down on the ground with conventional stones (5). ADVANTAGE  - Reduced costs and savings in time, when courts have to be made ready for use after the winter break.
Patent DE-4312205-A1 (DE)
Title: Supercharged IC engine control appts. - has shorter valve overlap and later intake valve closing for lower engine speeds than high ones
Inventor: HITOMI MITSUO
IPC: F02B29/08
Filed: 1993-04-14
Abstract: The supercharged IC engine has variable valve timing. The control circuit (61,50,51) ensures that the intake and exhaust valve overlap is longer for higher engine speeds than for lower speeds. When the overlap period is short, the inlet valves close at a later time than for longer overlap periods. The overlap period for low engine speeds is controlled so that the time taken for an upward piston stroke to TDC is shorter than a downward stroke away from TDC. There is a masking section in the cylinder head around the edges of the exhaust valve seats; for low engine speeds, the valve stroke is less than the mask height, but it is greater than mask height for high engine speeds. ADVANTAGE - Prevents blow out, improves antiknock properties and keeps intake air temperature below critical point.

Title: Squeeze valve with toggle catch
Inventor: EICHLER DIETRICH DR
IPC: F16L55/10
Filed: 1993-04-26
Abstract: The invention relates to a device for metering liquids in which solids and coarse substances are contained. The main field of application of the device is in the area of agriculture and there in the metering of liquid manure. The aim of the invention is to design a valve in which no coarse substances can collect at edges, good adjustability is possible, and other faults can be avoided by rapid opening of the valve without the presetting of the metering being lost. According to the invention, this object is achieved by the edge being arranged at the pipe branch in such a way that the liquid flushes the same clear in the main flow direction, the quantity to be metered is set via a toggle-lever joint, and the entire cross-section of the pipeline is cleared by fully opening the opening handle across the dead centre of the toggle levers.
Patent DE-4315617-A1 (DE)
Inventor: HORN MANFRED
IPC: E05F15/655
Filed: 1993-05-11
Abstract: A swinging and sliding door for vehicles, in particular public transport vehicles. A horizontally extending running rail (4) in which a roller guide (5) engages is arranged on the inside of the door wing (2) essentially in the region of the horizontal centre. The roller guide (5) is held in an intermediate mount (6) which is displaceably held in a mount (6) which is permanently connected to the body of the vehicle. During the opening movement of the door, the door wing (2) is moved initially outwards in a first movement step (Ö1) before being displaced laterally on the roller guide (5) in a second movement step. During the closing movement of the door, after moving into the door opening the door wing is given an additional movement parallel to the displacement direction of the second movement step (Ö2) in the reverse direction with respect to the first movement step (Ö1). This results in locking devices arranged on the door wing (2) engaging one in the other. The locking elements are arranged on the vertical side edges of the door wing on a frame (14) which runs all around the inside of the door wing and provides rigidity while their counter elements are located on the door frame (1). <IMAGE>

Title: Method for operating twisting spindles and apparatus for carrying out the method
IPC: D01H1/42
Filed: 1993-05-26
Abstract: A method for operating twisting spindles and an apparatus for carrying out the method. In the method, the run of the thread (F2) through the thread balloon delimited by a balloon limiter (3) is periodically disturbed in such a way that transverse waves form within the thread balloon over the thread length, such that the thread balloon touches the inner face of the balloon limiter at individual points only, so that, for each thread element of the thread running through the thread balloon, there is a time of non-contact after a time of contact with the balloon limiter. To generate the transverse waves, the thread is guided through an undulator ring (6) which can be set in vibrations and which is arranged in such a way that the rotating thread (F2) touches it on the inside. An oscillating movement of predetermined frequency, direction of vibration and amplitude is imparted to the undulator ring (6). <IMAGE>
