Patent DE-4105463-A1 (DE)
Inventor: HERFURTH MICHAEL
IPC: H02M1/00
Filed: 1991-02-21
Abstract: According to a process for controlling a voltage transformer having a wide input voltage range for full sine mains current consumption, the input current of the voltage transformer is controlled or regulated in dependence on a current set value. The output voltage of the voltage transformer serves a a real input value for a regulator that generates a regulating signal in dependence on an output voltage set value. Said current set value is obtained by multiplying a signal that is proportional to the rectified input voltage of the voltage transformer by said regulating signal, as well as by a direct voltage signal that is inversely proportional to the peak value, the effective value or the mean value of the input voltage of the voltage transformer. This process is preferably used in a clocked voltage transformer, such as a blocking oscillator type converter, a high-pass or a high-low pass transformer.

Inventor: BERNHARDT WOLFGANG
IPC: B60T8/48
Filed: 1991-06-29
Abstract: The braking system (1) has a brake line (5, 6) which extends between a master brake cylinder (3) and at least one wheel brake (for example 8), and which has a valve arrangement (22), for brake pressure modulation, switching phases of pressure-build-up, pressure holding and pressure- reduction in the wheel brake.

Title: Additionally roughening surface of thermoplastics e.g. to non-skid state - by e.g. heating to form soft surface skin and applying suitable particles so that they become embedded
Inventor: BURGDORF MAERTEN DR
IPC: B29C59/04
Filed: 1992-03-06
Abstract: The surface roughness of thermoplastics is increased by oxidising or heating it after it has been moulded, applying grit particles to the surface and bonding them on to it or embedding them into the partially softened surface film. The surface of a moulding is roughened additionally by a system with a flame burner, a jet of grit and a second flame burner. The flames can be replaced by e.g. radiant heat or hot airjets etc.. This complete system is moved across the moulding or the latter is moved through the jets etc.. The flames raise the surface of the moulding to 150-200 deg.C. and produce a softened skin. The grit particles are preferably smaller than 0.5mm dia. and they fall into this skin. The second flame causes the grit to sink better into the surface. The grit is e.g. aluminium particles but is pref. granules of the same polymer as that of the moulding. ADVANTAGE - The method concerned is simple. It increases the roughness of the non-skid properties.
