Title: Electronic indication of relative humidity - uses wet and dry bulb thermometer with operational amplifier summation circuits
Inventor: SCHAEFER ECKEHARD
IPC: G01N25/62
Filed: 1975-05-14
Abstract: Both temperature probes (1, 2) can be silicon diodes, thermistors or thermoelements and are connected to operational amplifiers with linear amplification and adjustable gain (3, 4). The outputs of the amplifiers are connected to a differential amplifier (5) whose output is proportional to the temperature difference Tr-Tf. The output of this amplifier together with the output of the dry-bulb thermometer (4) is fed to a multiplier and divider circuit (6). The multiplier and divider are supplied with a reference voltage (Vo) and a second voltage (Vt) which is an adjustable DC potential. This serves as a summing voltage for the value respective to the output of the dry-bulb temperature. The output of the divider and multiplier is a voltage proportional to relative humidity. This output follows a non-linear curve. A linearising circuit provides an acceptable signal for display or plotting purposes.

Title: Flat semiconductor elements prodn. - has small volume of fused layer on surface of host substrate subjected to heating and cooling
Inventor: MATARE HERBERT F
IPC: H01L21/208
Filed: 1975-12-18
Abstract: The high quality and reliable production technique is suitable for flat semiconductor elements, such as for example light emitting diodes.

Title: Temp. control for heating element - determines resistance and hence temp. from current and voltage, to control triac switch
Inventor: SUESSE HEINZ ING GRAD
IPC: G05D23/24

Abstract: The temperature regulator, for controlling an electrical heating element, determines the element's temperature by measuring the current flowing through it and the voltage across it in two channels. The channels consist of input transformers coupled to the element and feeding two rectifiers. The rectifiers' outputs are combined into a single signal representing the resistance of the element -- and therefore its temperature. This signal is compared with a reference. The comparator's output is amplified, transformed and used to control the triac switch in series with the heating element.
