Title: Radial ventilator for cooling system of motor vehicles
Inventor: EHLERS MICHAEL DIPL ING
IPC: F04D29/16
Filed: 1997-04-03
Granted: 1998-04-16
Abstract: The invention relates to a radial fan, specially a ventilator for the cooling system in a motor vehicle, comprising a rotor (3) with radial blades (4), a nozzle-shaped covering disc (5), an air guide ring (6) fixed thereon, a rotor base and a stationary inflow nozzle (8).

Title: Calibration of calender rollers, for processing paper or cardboard gives a pilot setting and adjusts the pressure at the lower roller support, with support pressures registered when the upper roller nip is fully closed
Inventor: KAYSER FRANZ
IPC: D21G1/00
Filed: 1999-08-27
Granted: 2001-02-08
Abstract: Gives a pilot setting for rollers of a calender. The internal support (15) for the lower roller (4) is subjected to pressure, and to close the nips (18,19), the external/ internal supports (13,4) for the lower roller (15) are subjected to an increasing pressure. The effective pressure at the outer and inner supports (11,13,15) is registered at the moment when the upper nip (18) is fully closed. The internal support (15) for the lower roller (4) is subjected to pressure so that the roller mantle (14) forms a cylinder around its horizontal axis. The pressure from one support (15) to the lower roller is followed by pressure from the other support (13). To close the upper nip (18), the pressure is reduced at the inner support (11) for the upper roller. The same pressure is applied to all the inner and outer support systems (11,13,15), and the pressure change is continued automatically until the point when the upper nip (18) is fully closed. The pressure change for the inner support (15) for the lower roller is set so that the ends of the mantle are at a constant gap from the roller carrier (12). Compensation is made for the overhanging weights, for at least one center roller (3). An Independent claim is included for a calender assembly with a measurement system (20,21) at least one end of the uppermost nip (18), to generate a signal when the nip (18) is closed. A unit which receives the signal is triggered to register the pressure at the supports (11,13,15). The measurement units (20,21) have an optical action, where a light chamber is interrupted when the nip (18) is closed. A control sets the pressure for the inner or outer supports (15) for the lower roller (4), to keep the ends of the mantle at a constant gap from the roller carrier (12).

Title: Command authentication process
Inventor: TOMAS DZH MIKHM
IPC: H04L9/32
Filed: 1992-11-20
Granted: 1999-09-10
Abstract: FIELD: transmission of secret commands. SUBSTANCE: driven station such as orbital satellite and driving station such as ground control station have their own lists of random fillers. Lists of driving and driven stations are identical. When driving station transmits critical command to driven station, one of fillers is combined with command and transmitted to driven station as data transmitting message. Each filler is used only once. Driven station estimates filler value received using its own version of same chosen filler. If estimate results in coincidence, command is taken as genuine and driven station executes it. Random fillers are generated by driven station. They are asymmetrically ciphered in ciphering process and transmitted to driving station so as to make both stations operate with same sets of fillers. EFFECT: improved degree of secrecy of authentication. 28 cl, 9 dwg
