Title: Air conditioning humidifier with immersion heated tank - incorporating temp sensor to regulate immersion heater and water feed valve
Inventor: WAGNER EGON
IPC: F24H1/00
Filed: 1972-12-13
Abstract: An air humidifier, esp. for air conditioning plants, comprises a tank for water, an immersion heater entering through one end wall of the tank and a water level regulator. The immersion heater has a heating section adjacent to the end wall through which it enters, and this end wall, together with this heating section are made of heat conducting matls.; a thermostat is mounted in the same end wall at the desired water level and acts to switch on and off the immersion heater and also a solenoid valve which regulates the make-up supply of water to the tank. When a predetermined temp. in the heating section adjacent to the end wall, exceeding 100 degrees C is reached the heater is switched off and the solenoid valve is opened to admit more water. Pref., a second temp. sensor responding to a lower temp. than the first is used as a secondary defence for preventing overflow of the tank.

Title: Hot gas circulation multi deck baking oven - for bread prebaking and finish baking after temperature reduction
Inventor: FISCHER GEORG
IPC: A21B1/02
Filed: 1973-03-28
Abstract: Bread baking oven is heated by hot air which is kept in circulation by a fan and heated by a gas or oil burner. After using for a few minutes at a high temp. as a pre-baking oven, the temp. is lowered by entraining cool air to a temp. at which the oven continues to complete the finish baking of the bread. This enables smaller bakeries to produce pre-baked break varieties without having to instal two separate baking ovens. Transfer of dough from one oven to another which may disturb the dough is eliminated.

Title: Machine tool copying stylus for three axes - has stylus displacement measurement and restoring spring system
Inventor: ZOEBERLEIN DIETER
IPC: G01B7/012
Filed: 1973-09-14
Abstract: The copying stylus for scanning the master template on a machine tool has a measuring system for analysing the displacement of the stylus in the sensing axis and it has also a measuring system for analysing the displacements in the plane at right angles to the stylus axis. Spring actuated restoring forces are generated which act in the opposite direction to the stylus deflections. The signals generated by the measuring system are used for operating a machine tool. The copying stylus is designed so that no matter what the stylus finger length the copying error is maintained at minimum value. The ratio between the displacement of the stylus finger and the restoring forces in given axis can be adjusted for every given stylus length. Hence the ratio of the measuring signal in the measuring system for the plane normal to the stylus displacements remains constant in relation to the output signal of the measuring system in the stylus longitudinal axis.

Title: Automatic turret lathe control system - has switching elements for a given series of operations, coupled to a basic program control unit
Inventor: KANAL MAX
IPC: G05B19/04
Filed: 1973-09-17
Abstract: The automatic control system of an automatic turret lathe has a central main basic programme with programme stations.

Title: Electric motor speed control cct - uses differential counter for actual and required speeds to control electromagnetic shaft coupling and brake
Inventor: ORTLIEB WOLFGANG DIPL ING
IPC: H02P29/00
Filed: 1974-03-18
Abstract: The speed control circuit for a sewing machine motor has a counter circuit to compute the difference between drive voltages representing the motor actual speed and its required speed. The resulting difference or error signal is passed to a summation amplifier where an alternating voltage of constant amplitude and frequency is superimposed on it. The constant alternating voltage is derived from a clock pulse generator. The summation circuit output is passed one way directly to a first amplifier and the other way over an inverter to a second amplifier. The first amplifier controls the stages serving the motor electromagnetic shaft coupling, and the second amplifier controls the stages serving the motor electromagnetic brake.

Title: Combined pressure sealing and retaining ring - uses square section ring of relatively hard elastomeric material
Inventor: NAWRATH PETER
IPC: F16J15/06
Filed: 1974-03-26
Abstract: The device simplifies the retaining of the end covers of hydraulic or pneumatic cylinders.

Title: Temperature measurement evaluations - for thermocouples and resistance thermometers with values independent of terminal or ambient temps
Inventor: HANS PETER
IPC: G01K7/02
Filed: 1974-11-07
Abstract: Three separate measurements are carried out using the same meas. system. Before each measurement the system input is short circuited to obtain the voltage drift at the output of an analogue/digital convertor. The digital drift is fed into a binary forward/backward counter so that when the measured voltage is fed in, the counter contains the digital value of the drift-free measured voltage. In the second measurement a thermocouple voltage is evaluated and a corresponding digitalized and linearized value is stored in a read/write memory. In the third measurement a resistance thermometer is used to measure the thermocouple voltage and this value is evaluated and stored in a computing device.
