Patent DE-3907897-A1 (DE)
Title: Vacuum switch having external axial magnetic field excitation
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1989-03-09
Abstract: Previously produced external excitation windings (7) arranged around the switching housing (1) [lacuna] the magnetic field strength required to interrupt the current in the switching space between the contacts (4, 6), in a positive manner in the entire turn area. A greater cost is necessary for this purpose than with the required field strength being produced only in the switching space. This disadvantage is overcome by a magnetic conductive body (13) arranged on the rear side of the stationary contact (6). This magnetic conductive body (13) is also located in the pull-in region of the magnetic lines of force in the interior of the excitation windings; its effect is somewhat comparable to that of a pole shoe. With regard to the shape, a truncated-conical-shaped body (frustrum-shaped body) is particularly well suited as the magnetic conductive body. The electrical conductor (5d) is accordingly designed as a hollow truncated cone which accommodates the truncated cone. The design of the stationary electrical conductor as a hollow truncated cone also results in a considerable advantage for the electrical conductor itself, since it enables a particularly short current path to be produced to the external excitation windings (7), and makes a closed switching housing base possible. <IMAGE>
Patent DE-3910991-A1 (DE)
Inventor: SUDAU PETER
IPC: B65H18/26
Filed: 1989-04-05
Abstract: The method for controlling the pressure-roller setting of a web winder, which has become known as step control, is to be improved to the effect that even thin webs can be wound onto the winder spindle without being damaged. For this purpose, the pressure rollers bring the web as near as possible to the winder spindle, but without exerting pressure forces on the winder spindle, or only the pressure roller which is last in the web feed direction presses the web against the winder spindle, whereas the remaining pressure rollers lay the web as near as possible to the winder spindle, without exerting pressure forces on the web and the winder spindle. The slip-free laying of the web against the winder spindle is achieved by position-controlled spreading of the spindle segments.

Title: Colour pattern scanning - has opto-electronic scanner to identify reference colours and colour points with three colour components for identification
Inventor: THOMAS WOLFGANG DIPL ING
IPC: G01J3/50
Filed: 1989-07-06
Abstract: To identify the colours in the colour pattern for a printer or textile mfg. assembly, reference colours are selected w.r.t.  number and shade, and the original pattern is at least partially scanned opto-electronically and trichromatically.  The reference colours are assigned identification symbols w.r.t. their triple colour component make-up. The pattern is wholly scanned opto-electronically, and each colour point and triple colour component is compared with the reference colour. Each colour point and triple  component is arranged with the reference point which has the closest vector shift to it with the identify symbol, so different colour points in the pattern can have the same symbols. The symbols of the colour points in the pattern match the variety of reference colours in the colour picture. ADVANTAGE - Technique gives the reproduction required, from the pattern, with only variations allowed within the limits of the scanning.

Title: Regulation of industrial sewing machine - employs automatic control for cloth advance mechanism
Inventor: ROHR GUSTAV DR ING
IPC: D05B69/20
Filed: 1989-10-31
Abstract: Industrial sewing machine is operated using a control on the cloth advance mechanism to compensate for the movement of the needlebar, taking into consideration the time lapse required, and whether the cloth is being sewn in a forward or reverse direction, or with a change of direction. ADVANTAGE - The compensation mechanism for the relative number of stitches at varying speeds and according to cloth progress direction is controlled accurately, so that the stitches are regulated at starting, stopping and reversing. Pref. the order of movement of a needlebar is not the same as the cloth advance mechanism. The needlebar must form stitches and lift clear before the cloth is advanced, in either direction, or else on reversal, too many stitches are formed, with untidy sewing.
