Patent DE-3814750-A1 (DE)
Title: Device for driving a lubricant pump of an internal combustion engine
Inventor: DEUTSCHMANN HERBERT
IPC: F01M1/16
Filed: 1988-04-30
Abstract: The invention relates to a device for driving a lubricant pump of an internal combustion engine. A steplessly shifting planetary gearing serves for this purpose, which is coupled to a first transmission element, preferably to the ring gear of the internal combustion engine and to a second transmission element, preferably the sun gear, which is connected to the drive of the lubricant pump, and to a third transmission element, the planet carrier with the planet wheels, which is drive-connected to a regulating pump. The regulating pump, connected to a control valve, serves as control device, which adjusts the transmission ratio as a function of the pressure of the pumped lubricant. With the internal combustion engine idling, the control valve prevents the delivery of lubricant by the regulating pump. As a result the planet carrier is fixed. At higher speeds of the internal combustion engine the transmission ratio is adjusted so as to reduce the speed. A passage in the control valve is opened by the lubricant pressure, thereby allowing the delivery of lubricant by the regulating pump. If the regulating pump turns, however, so does the planet carrier and the lubricant pump works more slowly until the desired lubricant pressure is established. An approximately constant lubricant pressure can thereby be achieved over the speed range of the internal combustion engine. At all operating points... Original abstract incomplete.

Title: Coupling for toy and model vehicles, especially model railway rolling stock
Inventor: ZETZSCHE ALFRED
IPC: A63H19/18
Filed: 1988-06-10
Abstract: Whereas known uncoupling devices which operate by means of frictional fitting, especially when they are applied specifically for shunting locomotives at both ends of the locomotive, in practice also need two separate uncoupling elements per locomotive, in the case of the device according to the invention only one uncoupling element is necessary, being designed as a double-armed lever, in a manner such that it performs unaided the functions of the two separate uncoupling elements and, since only one bearing is required, also has a lower power requirement.

Title: Monitoring circuit for timing element - provides start monitoring by switching pulse oscillator frequency to higher value
Inventor: BURGDORF ACHIM
IPC: F24H9/20
Filed: 1989-08-03
Abstract: The circuit has a pulse oscillator, behind which a binary counter is coupled. As each heater (106) starts, starting monitoring occurs in the timer (107) such that the pulse oscillator (105) frequency is switched to a higher value. The binary counter (29) triggers the switching-on of the heater during start, but switches it off if exhaust gas excapes. The start monitoring uses different signal states at the outputs of the binary counter. After a preset time, the frequency of the pulse oscillator is changed over to the original, low value. The binary counter is connected at a frequency divider, all outputs being pref. set first to a zero signal value. Then a logic circuit forms frequency determining switching elements of the pulse oscillator, with two series connected capacitors. USE/ADVANTAGE - Disconnecting fuel fired heater upon exhaust gas escaping. Monitors correct functioning of timer.

Title: Biomass layer thickness determination - by comparing associated rates of liq. flow and gas prodn. or consumption
Inventor: OTSCHIK JOACHIM DIPL ING
IPC: C12M1/34
Filed: 1989-08-11
Abstract: In bio-reactors, used e.g. for sewage treatment, the microorganisms forming the bio-massmay be immobilised on a fixed or floating fed of filler bodies.  Whether with aerobic or anaerobic continuous processes, a point is reached where the further thickening of the mat of material is not beneficial, and surplus biomass must be stripped from the bed. To determine this point, an axial fluid flow is created.  Gas productivity, i.e. amt. produced or amt. consumed depending on nature of process, is continuously measured, e.g. in an inserted tube and related to the fluid flow speed.  That thickness is determined from a set of standard graphs produced for the particular substrate.
