Title: Gas-turbine-burner operating system - delivers steam and oil into air current via different nozzles
Inventor: BECKER BERNARD DR ING
IPC: F23D17/00
Filed: 1991-03-21
Abstract: The burner-operating method is particularly for a gas turbine, this having a main-burner system (4, 7), preferably with an annular air feed passage (4). In the latter are turbulence-inducing vanes (7). A larger number of first outlet nozzles (11) deliver a first and gaseous medium (B), and second ones (14) a second and liquid medium (C) into the main air current (A). Steam forms the first medium and oil the second. Alternatively, gas and water can be used respecitvely instead. The first nozzles can be above the vanes and the second ones in the same plane as the vanes. USE/ADVANTAGE - Reduces nitrous oxide emission and is usable with different fuels.

Title: Protecting drive motor of electrical power tool - controlling zero voltage releaser and excess current releaser by drive current
Inventor: FREITAG MANFRED
IPC: H02H3/24
Filed: 1991-06-17
Abstract: The device is partic. for the motor of a portable drilling machine for concrete drilling, and protects against thermic overload.

Title: Temperature and heat transfer coefficient measurement esp. for cervical mucus testing - calculating heat transfer coefficient of probe from substance temp. determined from temp. curve
IPC: G01N25/18
Filed: 1991-10-29
Abstract: The method involves using a probe to measure the temperature of a substance, e.g. cervical mucus, for n steps of a measuring cycle, until the substance temperature is measured continuously. The individual output signals are used to calculate a sequence of slope values of a temperature curve which is determined until the slope values no longer fall or rise. The final value of the slope corresponds to the substance temperature and it is used in a formula to calculate the time constant tau for the measuring probe. The heat transfer coefficient of the probe is then calculated in terms of tau and a known constant. ADVANTAGE - Quick, exact, on-the-spot measurement. ,D20
