Patent DE-3811359-A1 (DE)
Inventor: BLASIUS UDO ING GRAD
IPC: B41F33/00
Filed: 1988-04-02
Abstract: Measuring head 9 is responsible for monitoring registration marks 14 on travelling web 11 in a printing machine; head 9 is movable transversely of the web on a cross member so as to be positionable for different formats. This positioning is accomplished by lead screw 12 and motor 13 under the control of input signals which establish the desired lateral movement on the basis of measurements made initially on a printing plate or a specimen printed product; coarse positioning can be supplemented by automatic fine positioning where the head searches a defined region and sets itself to the sensed marks. The initial input data is created from the inking zone control console, Fig 1, the position of the register marks being associated with a particular inking zone or even a sub-division within an inking zone. <IMAGE>

Patent DE-3828307-A1 (DE)
Inventor: WINNER HERMANN DIPL PHYS DR
IPC: G01P15/13
Filed: 1988-08-20
Abstract: In an acceleration sensor (10), which consists of a bending spring (11) with strain-sensitive sensor resistors (14) and a seismic mass (13), a holder (15) for a plunger coil (17) is fitted on the bending spring (11). The plunger coil (17) interacts with a permanent cup magnet (18). The sensor resistors (14) and the plunger coil (17) are part of a closed electronic circuit, which has, as essential components, an active high-pass filter (25) and a voltage-controlled current source (29). The measuring signal produced by means of the sensor resistors (14) and a bridge amplifier (24) is coupled with negative feedback via the high-pass filter (25) and the voltage-controlled current source (29) as current through the plunger coil (17). as a result of which an active electronically controlled damping of the acceleration sensor (10) is possible. The sensor damping can be adapted to the respective conditions, and also the frequency range of the acceleration sensor (10) can be increased. Adder (27) produces a weighted addition of the output of amplifier (24) and filter (25). At low frequencies the filter (25) acts as a differentiator so that the force exerted on the coil (17) is proportional to the coil velocity i.e. viscous damping. Above the filter cut-off frequency the force exerted is proportional to the deflection of the seismic mass (13), increasing the effective stiffness of the spring (11). Instead of strain-sensitive resistors (14), a capacitive pick-up is envisaged. <IMAGE>

Inventor: VELTRUP ELMAR M DIPL ING
IPC: F16L55/16
Filed: 1988-11-19
Abstract: The invention relates to a process for the partial reconstruction of pipes, especially drainpipes, in which the damaged location is covered on the inside with a coating. So that even inaccessible pipes can be partially reconstructed, a sealing strip is to be laid in the peripheral direction around a tubular balloon whose periphery corresponds to the inner periphery of the pipe to be reconstructed. The balloon, laid flat, together with the sealing strip is folded once or several times to form a pack. The pack is put into the pipe up to the damaged location. The balloon is unfolded there and inflated until the sealing strip bears on the inside against the pipe and seals the damaged location. The balloon is then removed again from the pipe. <IMAGE>

Title: Method for thermal surface (superficial) hardening using energy beams
Inventor: PANZER SIEGFRIED DIPL PHYS DR
IPC: C21D1/09
Filed: 1989-03-16
Abstract: The method for thermal surface hardening using energy beams serves the purpose of producing hardened tracks, in particular slideways of work guides (plates) of machine tools. According to the invention, before the transfer of energy onto the hardened track a compensation hardened track is produced on the side opposite the hardened track in accordance with the distortion (warpage) characteristic of the component, which is a function of the energy transfer conditions. After temperature compensation, the residual distortion is measured and after comparison with the permissible values one or more further compensation hardened tracks are produced until the permissible distortion value is reached.
