Patent DE-4211319-A1 (DE)
IPC: B22F3/12
Filed: 1992-04-04
Abstract: The process for making a sintered component, which is pore-free in some zones or edge zones but porous in the remaining zones, from iron materials starts from a component brought by conventional powder-pressing and sintering processes to a residual porosity of about 10% by volume. By means of additional process steps, which essentially are the zonal introduction of additional materials or local mechanical recompaction, these zones are brought to a residual porosity of 5% by volume and less; this produces a closed pore structure. Under these set conditions, the sintering component can be brought in a final HIP process step or sintering-HIP process step in the pretreated zones to a material density of 100% or to complete freedom from pores. Essential advantages: local improvement of the material properties, ability of the finished sintered components to be calibrated.

Title: Ring spinning frame - has monitor devices to detect faults at high or low spindle speeds
Inventor: WOLF HORST
IPC: D01H13/14
Filed: 1992-08-26
Abstract: A process for monitoring a section of a ring spinning frame, during starting, running and stopping. At least one spindle with a drive motor is periodically monitored for spindle speed or load at the motor to give a factual signal which is compared with the parameters contained in a programme from a memory device. The parameters are selected to compare with average running, so that input signals which are above or below indicate a different type of fault in each class. There is a time lapse between the signal with an alarm and actual stopping of the spindle or the machine. The appts. is also claimed. Typically a spindle (3) on one position of a ring spinning frame (1) may having a motor drive (5) with a controller (9). There is a stop/start switch (7). A revolving part of the spindle (11) has a permanent magnet attached. A receiver (15) is connected to a pulse generator (17). The output is detected at the comparator (21), so that the basic programme held in the memory unit (24) may be read by the control unit (26), and the high or low output can be monitored at the unit (25). This in turn signals the high, low or average output to the device (27) which acts accordingly. USE - The system is able to identify a range of faults, such as broken yarn, faulty traveller, soft cop, drive belt slack, overload at motor, etc., and would give time for a fault to clear before the machine is stopped.

Title: Plate-cylinder alignment guide in rotary printing press
Inventor: BECKER WILLI
IPC: B41F13/28
Filed: 1993-01-27
Abstract: The lateral and oblique alignment system is for a cylinder working at one side in an adjustable eccentric bush, by which it can be set on an oblique position when stopped or with the press running. A further mechanism slides the cylinder axially to correct lateral alignment. While the plate on it is printing and dependent on the oblique setting, the cylinder is slid nearly linearly for an adjustable amount by a control mechanism, being returned to the starting position at the groove in it. There can be a pivoting forked bridge-piece (17) supported by an adjusting screw (13) for lateral alignment, and with a pendulum bearing (29) on trunnions (30) on it at right angles to the cylinder axis (47). This has a roller (31) clear of this axis and running against a cam (32) fixed to the cylinder trunnion (4). A shoe (37) sliding in the bearing in the lengthwise direction of the bridge-piece has a supporting roller (19) coaxial to the bearing axis. This is supported by a thrust plate on the trunnion in opposition to a compression spring acting against the trunnion at the opposite end. The shoe slides in the bearing to give a positive or negative distance between the roller and trunnion axes, transmitting the pendulum movement generated by the cam and sliding the roller for the amount of oblique correction set by the eccentric bush.
