Title: Receiver for IR control system - uses optimal filter processing to verify incoming command bit streams
Inventor: KOHLBACHER GERHARD DIPL ING
IPC: H03J9/06
Filed: 1980-02-20
Abstract: A monolithic integrated circuit structure comprises a first optimal filter (3) to verify the incoming bit stream followed by parallel optimal fibres (4) and adjustable amplitude detectors (5) which respond to a predetermined bit stream sequence. The optimal filters comprise shift register chains with specific delay line characteristics and an overall summation to establish the signal value of the bit stream. The incoming signal (E) carries l.f. plus or minus 100 Hz. interference and 2.5 to 3.5 kHz light scatter interference. A preliminary filter (1), e.g. a notch filter, removes this and feeds the signal to an amplitude liminting amplifier before supplying the optimal filters. The first optimal filter uses a pulse answering sequence to verify the incoming signal before feeding to the parallel optimal filters (4), at e.g. 34.64 kHz and 37.31 hHz for two channels (I, II). Valid signals are compared after the amplitude detector (5) for correct correlation in the comparator (6).

Title: Non-gravimetric measurement of diffusion resistance factors - by measuring half value times of equilibrium moisture disturbance recovery
Inventor: SPEIDEL KARL
IPC: G01N13/00
Filed: 1980-08-06
Abstract: The method of non-gravimetric rapid precision measurement is for the diffusion resistance factors of solids and does not involve the use of a precision balance and can accomodate considerably larger test surfaces than can gravimetric test methods. A control measurement chamber (B), pref. of octagonal shape, is sealed at both ends with similar material samples (5,6) of exactly equal surface areas forming hermetic seals. This enables the equilibrium moisture level between the moisture and drying chambers to be not only measured but also disturbed by introducing a very small quantity of water or steam. The diffusion resistance factors of the dry and moist regions are determined from the half-value times of the disturbance recovery using precalculated multiple column tables whose starting points from the possible equilibrium moisture percentage levels.

Patent DE-3102918-A1 (DE)
Title: Sensor for detecting nonequilibrium states in gases
Inventor: REBER HARALD DR
IPC: G01N27/16
Filed: 1981-01-29
Abstract: A sensor is proposed which is used to detect nonequilibrium states in gases, in particular in exhaust gases. The sensor consists of a carrier plate on which four resistors are provided and connected to form a Wheatstone bridge. Two of these resistors are exposed to the gas and two are protected from it. The resistors exposed to the gas consist of a material which, on the one hand, catalyses the establishment of the thermodynamic gas equilibrium and whose resistance, on the other hand, is temperature-dependent. In the event of nonequilibrium, equilibrium is established at said resistors, and the heat of reaction occurring in this process alters the temperature and, consequently, also the value of said resistors, thereby unbalancing the alignment of the bridge. This signal is fed to a suitable evaluation circuit. <IMAGE>

Title: Appliance suitable especially for the aeration of liquid manure
Inventor: GEISBERGER MAX
IPC: B01F3/04
Filed: 1981-03-12
Abstract: An appliance suitable for the aeration of liquid manure, in the form of a cushion or a mattress, is described. This is clamped, if appropriate on all sides, in a flat holding frame. The cushion or mattress (3) has a connection, via which, for example, compressed air is supplied. The cushion or mattress consists particularly of natural split leather, preferably chrome leather. During operation, small air bubbles escape through the fine pores of the leather and are distributed in the adjacent volume of liquid manure. As a result of the large number of individual bubbles, the specific gravity of the liquid into which these bubbles have penetrated decreases. The liquid rises; liquid manure flows after it from the sides: the desired circulation effect is obtained. <IMAGE>
