Patent DE-3823332-A1 (DE)
Title: Device for a reciprocating piston engine with variable camshaft
Inventor: SCHMID ERICH
IPC: F01L13/00
Filed: 1988-07-09
Abstract: Device for a cam-controlled reciprocating piston engine with a camshaft (1), by means of which the sequence of movements of the inlet valve (2) can be varied so that it is possible to control the load without a throttle valve. In this system the camshaft (1) is axially displaced resulting in a variable cam curve for the valve lift and the valve closing point. This is achieved in that the cam (3) is cylindrical on the cam base circle, whereas the shape of the cam lobe is different on the faces I and II. This results in a cam path which is conical and asymmetrical in this area. Due to the flexible hemispherical bearing (7) of the rocker arm (4), the latter can conform non-positively to the inclinations of the cam curve, on the other hand due to the leverage of the rocker arm (4) the greater valve lift curve results from the cam curve. As the inlet valve (2) closes, the cam curve declines with varying steepness depending on the axial position of the camshaft (1). For gentle setting down of the inlet valve (2) a valve brake (12) is thereby necessary, which also fixes the rocker arm (4) between its tappet (13) and the bucket tappet (6) of the inlet valve (2) when the cam curve runs inside the cam base circle and the rising nose (9) of the rocker arm (4) therefore does not have any frictional connection with the cam path. <IMAGE>

Title: Use of additive mixtures as a means for increasing the vaporisation rate and combustion rate and also the combustion stability of liquid propellants and fuels injected into rocket combustion chambers or high-performance combustion installations
Inventor: BSCHORR OSKAR DR RER NAT
IPC: C10L1/14
Filed: 1988-10-18
Abstract: Additive mixtures which consist of a) organic compounds with highly conjugated  pi -bond systems and longwave main absorption bands in the wavelength range from about 350 to 1200 nm, b) organic surface-active substances and c) organic solvents and suspending agents for the components a and b, are used as agents for increasing the vaporisation rates and combustion rates and also the combustion stabilities of liquid propellants or fuels and oxidisers for rocket engines or other high-performance combustion installations which are likewise operated with liquid fuels and in which there are combustion problems comparable to those in rocket engines and caused by disturbances in energy transfer. The additive mixtures are injected into the combustion chamber together with the propellants or fuels and the oxidisers with uniform distribution, which is as symmetrical as possible, in a geometrically optimum manner in accordance with defined economical methods. Owing to their property of exchanging radiation energy, highly conjugated  pi -bond systems effect in combination with surface-active substances faster, more uniform activations of major fractions of molecules participating in the combustion up to the stage of the state ready for reaction, which is tantamount to enhanced stabilisation of the combustion process.

Title: Electronic starting device for starting fluorescent lamps in radio-frequency operation
Inventor: BRUNE WILFRIED
IPC: H05B41/295
Filed: 1988-10-19
Abstract: So that the fluorescent lamp 12 which is operated at radio frequency starts successfully and without flickering over a wide temperature range, a circuit arrangement which consists of one or more individual capacitances 19, 20 in series with a parallel circuit consisting of a temperature-dependent resistor having a negative temperature coefficient 21, and a non-reactive resistor 22, are arranged in series with the heating electrodes 10, 11. The characteristic of the parallel circuit consisting of PTC thermistor 21 and non-reactive resistor 22 counteracts the characteristic of the heating electrodes 10, 11 (positive temperature coefficient) and causes a steady rise of pre-heating current and starting voltage until the lamp 12 starts. The slope of the rise adjusts itself as a function of the ambient temperature to the value which is necessary for a reliable and lamp-saving starting process. <IMAGE>
