Patent DE-19843980-A1 (DE)
Title: Interference suppression circuit for digital signals
Inventor: STEFFEN CHRISTIAN
IPC: H03K5/1252
Filed: 1998-09-24
Abstract: The circuit includes a chain of n registers (D1,D2,Dn), connected one after the other and clocked at frequency (PHI). A first and a second logic state of the input signal is stored in the registers. At least a part of the registers is connected on the output side to an evaluation unit (UG).  The evaluation unit produces a digital output signal (AS) which only takes on the second logic state if all registers of this part of the registers exhibit the second state simultaneously. The evaluation unit is an AND-gate.

Patent DE-19857903-A1 (DE)
Title: Determining volume of laundry in washing machine or dryer drum
Inventor: KAUFMANN REINHARD
IPC: D06F34/18
Filed: 1998-12-16
Abstract: Determining the volume of laundry comprises rotating the drum from centrifugal speed to a higher speed followed by braking to use the torque related speed control setting values. To register the volume of laundry in the drum of a washing machine, or dryer, the drum is accelerated from a rotary speed wu = w1 where the laundry lies on the drum mantle through the centrifugal force to a speed wu = w2 is greater than or equal to w1 for a time period T/2. The drum is braked with a negative acceleration until it reaches a rotary speed w1 in the same time span T/2, where the rotary speed run wu in the acceleration phase matches the rotary speed run wd in the braking phase. The torque-related setting values of the speed control are integrated or added over the time period T. The moment of inertia eta m of the laundry is taken from the integral or sum of the torque-relating speed control settings, taking into account the moment of inertia  eta t of the drum and the drum drive.

Abstract: The invention relates to a residual oil caused by the treatment of crude oil, natural bitumen or oil sand. The residual oil is mixed with grained, hot coke acting as a heat transfer medium (thermal coke) in a mixer and at a weight ratio of 1:3 to 1:30. A liquid residual film is produced on the grains of the thermal coke. Said film partially vaporises in the mixer. Gases and vapours and moist, sticky coke are withdrawn from the mixer. The mixture consisting of coke and residual oil is guided into a downstream stirrer pot and slowly moves downwards in said pot, whereby the mixture is stirred mechanically at a temperature ranging from 450 to 600  DEG C and preferably 480 to 550  DEG C. Dry, pourable coke is withdrawn from the stirrer pot. Sojourn time of the thermal coke in the stirrer pot usually amounts to 1 to 30 minutes.

original is optically read by the optical system. A
control unit detects a trouble in the optical system
by using information obtained from the reflected
light before and after the original is optically read.
