Each wall section (30a) has a pneumatic unit, such as a pressure cylinder.  Air escape openings are fitted where the web is formed. The feed roller (6) acts as a take-off roller, to draw the fiber material out of the reserve shaft (2). Each feed trough (7) is on a rotary mounting, at a common carrier (25) across the machine width which supports all the trough mountings.  Each feed trough (7) is under pressure from a spring or a pneumatic unit, all held at the common carrier (25). Each monitor has a unit to convert the longitudinal and rotary movements of the feed troughs (7) into electrical signals, as an inductive path movement monitor with a plunger magnet and a coil, or as a proximity initiator. The feed roller (6) is in a fixed position. Feed troughs (14) are at the lower end of the filling shaft (9).  Adjustable wall sections form part of the filling shaft (9) wall, rotating at one side on separate rotary mountings to swing outwards from the fitting at a shaft wall (9b). The lower feed troughs (14) are on swing mountings at a common carrier (33) across the machine width, under tension. The ends of the common carriers (25,33) are fitted to the side walls of the machine frame.
Patent DE-19829643-A1 (DE)
Title: Digital signature verification method
Inventor: OHTA KAZUO
IPC: H04L9/32
Filed: 1998-07-02
Abstract: The method involves generating a first random number as secrete information by each signing person. Information are generated using a public parameter and the first random number. The information and two half-wave functions and identification information used by the signing person are published. A second random number is generated and second information are generated by inserting the public parameter and the second random number in a function. A signature is generated with a signature function which is generated with a parameter. Information which include identification information are sent to the next signing person in line. The last signing person sends the information to the verifier. The verifier calculates the first information from the public information with respect to the identification information and calculates the half-wave functions. The second information are calculated and checks if the signatures are valid by comparing two equations.
