Title: Error compensation system for quadrature phase modulated carrier - uses control signals representing sine and cosine of phase error
Inventor: BIRTH WINFRID DIPL ING
IPC: H04L27/00
Filed: 1990-06-25
Abstract: The phase and frequency error compensation system detects the phase error of the carrier signal at the reception end, with 2 orthogonal signal components obtained by quadrature phase demodulation, used to provide correction signals by multiplying with respective control signals (K1,K4;K2,K3). The correction signals are added and subtracted in pairs, to provide 2 output signals (IS',IC'). The two control signals (K1,K4) correspond to the cosine of the phase error, and the second and third control signals (K2,K3) to the sine of the phase error. USE - For mobile telephone communications.

Title: Flexographic printing press - has block belt tensioning cylinder forming auxiliary driving roller
Inventor: WELSCHLAU UDO DIPL ING
IPC: B41F17/00
Filed: 1991-01-14
Abstract: The flexographic printing press has a frame containing guide rollers and an impression cylinder for the strip material to be printed. The printing mechanism has a supporting cylinder, two coaxial sprockets and a tensioning cylinder, while the printing block is mounted on a perforated endless belt. A drive mechanism for the belt acts via the sprockets, while an auxiliary one prevents the sprocket teeth jumping between the perforations. The tensioning cylinder (13) forms the driving roller for the auxiliary drive mechanism (17), while the supporting cylinder (3) rotates freely. The impression cylinder (2) is in fixed bearings in the frame (15), while the belt with tensioning and supporting cylinders is adjustable in the frame in relation to the strip material passing round the impression cylinder. An adjusting unit (32) is provided to the auxiliary drive, exerting an additional force on the belt (8) such as to be greater than the difference between the rearwards displacement force generated when the block passes through the gap (1) between the strip material and supporting cylinder and the maximum force generated by the sprockets (6) on the belt. When not printing, this force is less than the maximum exerted by the sprockets. ADVANTAGE - Simple matching of main and auxiliary drive mechanisms.

Title: Hydraulic control system to get different coffee strengths in vending machine - uses three hydraulic pistons, two being nested, to mix hot water at different pressures
Inventor: DUERIG CHRISTIAN DIPL ING
IPC: G07F13/06
Filed: 1992-02-04
Abstract: The coffee vending machine has a cup holder (2) which rotates to put a cup of coffee granules (52) into the position for filling with hot water (51). The water is forced through the coffee granules with different pressures to get different required strengths.
