Patent DE-4328555-A1 (DE)
Title: Paper-making machine twin-blanket drying section - has structured gap between suction deflection rollers in upper row of cylinders and blanket path at lower row to reduce web path
Inventor: KOTITSCHKE GERHARD
IPC: F26B13/10
Filed: 1993-08-25
Abstract: The drying section of a paper-making machine, with a twin-blanket drying group (13), has rows of upper (18,20) and lower (19) cylinders, and suction path deflection rollers (18') in the upper row. The space between the suction deflection rollers (18') and the blanket path at the lower row at a tangent to them, between guide rollers (29), is free of machinery parts or components. Pref., the gap between the suction deflection roller (18') and the lower blanket path is less than the roller dia. An air blowing chamber (21) is within the loops formed by the blanket paths, opposite the suction deflection rollers (18',19'), to blow air through the two blankets (OF,UF). At least two twin-blanket drying groups (11,12,13) are arranged in succession. At least one blanket drying group, in addition, is at the start of the assembly, where the web (9) together with a single continuous blanket follow a serpentine path together alternating between cylinders and suction deflection rollers. USE/ADVANTAGE - The drying section of the paper-making machine has two rows of cylinders, working with two blankets. The web paths between the upper and lower cylinder rows are reduced by about half in alternating between the rows. The risk of web fracture is greatly reduced, but not wholly eliminated.

Title: Tool heat control in injection moulding appts.
Inventor: LIEHR ERICH DR
IPC: B29C45/73
Filed: 1994-02-23
Abstract: To heat the tools for an injection moulding assembly, the heating is in two stages with different temp. conditions, for the starting phase and the static working phase. The starting phase ends when the temp. initially reaches or exceeds the nominal tool temp. The tool temp. is measured continuously during the whole cycle time at a geometrical centre point between the mould part contour and the coolant channels/surfaces and between the coolant entry and exit at a point sufficiently displaced from the mould contour. At a time point set by a machine control signal, a coolant pulse is generated at a time close to the injection action related to the heating during the previous cycle, to give the required heating during the time span of the max. temp. difference between the injected molten material and the cooling channel. Further coolant pulses are generated through an actual/nominal comparison up to a second time point if the nominal temp. is exceeded, with the second time point set by a machine control signal, close to the end of the cycle.

Filed: 1994-03-08
Abstract: Convergence yoke for improving the focusing with vertical correction coils LV41, LV42 and horizontal correction coils LH41, LH42 which are connected to a line for the vertical deflection signal and generate a barrel-shaped deflection field, whose magnetic shape is weakened to a greater extent without changing the magnetic force, or a balanced correction field without changing the magnetic force, in order thereby to improve the focusing of the electron beams, and having a core 40 which causes the vertical correction coils LV41, LV42 and the horizontal correction coils LH41, LH42 to generate a weakened barrel-shaped deflection field. In addition, the chromatic (comal) abberration is corrected in that the barrel-shaped deflection field and the cushion-shaped deflection field are compensated by each other in order to equalise the deflection fields without changing the magnetic force. <IMAGE>

Title: Prophylactive treatment method of keloids and hypertrophic scars
Inventor: VOSS PIERRE NICOLAS DR MED
IPC: A61B17/00
Filed: 1994-07-06
Abstract: The method involves inserting clamps, with suitable instruments, across the scar or wound to provide long-lasting stretching of the corium in the region of the wound or scar.

Title: Carrier tracking circuit for IQ demodulator
Inventor: EPPINGER BERND
IPC: H04L27/38
Filed: 1994-12-24
Abstract: The carrier tracking circuit has a voltage-controlled oscillator (4) providing a complex output signal (A) for the IQ demodulator (3), for converting the input signal (IF) into a baseband signal (B), fed to a decision stage (5) for recovery of the transmitted data stream.

The delay stage is followed by a multiplier (22), for multiplying the baseband signal with the complex correction signal.
