Title: Process for polymerization of olefinic monomers
Inventor: FEIRING ANDREW EDWARD
IPC: C08F2/38
Filed: 1997-08-04
Abstract: PURPOSE: Free radically polymerizable olefinic monomers may be polymerized by using a fluorinated alkyl sulfonyl chloride or bromide and optionally a lower valent metal compound as an initiator system.

Title: Method for the control of a hydraulic pump in a regulated braking system
Inventor: KOHL ANDREAS
IPC: B60T8/40
Filed: 1997-08-04
Abstract: PURPOSE: A method is provided to determine comparatively accurate velocity frequency by determining an exhaust capacity actually required in any circumstances. CONSTITUTION: In a method for the adaptive steering of a hydraulic pump in a braking system containing low pressure accumulators(NDS1,2), which receive the pressure derived during regulation from the wheel brakes and which are drained by the hydraulic pump(HP), the braking pressure curve(PR) is determined first for each individual wheel with the help of a wheel pressure model. On the basis of the wheel pressure model a volume model(VM1,2) is subsequently designed for each individual brake radius, reproducing the approximate level of the low pressure accumulators(NSD1,2). The maximum level(maxV) and the control frequency or the time interval(T) between the two consecutive braking pressure reduction phases(PH2) are determined. The hydraulic pump(HP) capacity is such that the time interval(T) between the two consecutive braking pressure reduction phases is precisely sufficient to drain the low-pressure accumulator(NDS1,2) entirely.
