Patent DE-4123957-A1 (DE)
Title: Rotary printing machine pressure control - has cooling system to cool side frames to control pressure between cylinders
Inventor: HOFFMANN EDUARD DR ING
IPC: B41F13/00
Filed: 1991-07-19
Abstract: A rotary printing machine has includes two cylinders (1,2) which are mounted on parallel shafts (3,4). These shafts run in bearings (5a,5b,6a,6b) which are mounted in the side frames (9,10) of the machine. The pressure exerted between the rollers tends to fluctuate with temperature fluctuations in the material of the side frame (9,10). To overcome this problem, temperature sensors (11,12) are fitted to the side frames in the regions of the bearings. These temperature sensors control the flow of a cooling medium, which cools the side frames, and is pumped from a cooling system (14,15). USE/ADVANTAGE - Rotary printing machine. A constant pressure is maintained between the printing cylinders.

The degree of vacuum is subjected to a pulsating fluctuation during the treatment. USE/ADVANTAGE - Apparatus for promoting the growth of hair. The apparatus can be operated by the person undergoing treatment and increases flow of blood to scalp.
Patent DE-4127560-A1 (DE)
Inventor: GROSS-HERING LUDGER DIPL ING
IPC: H04N1/191
Filed: 1991-08-19
Abstract: A printing head (1) with printing elements (11) arranged in a main direction (12) is moved to and fro linewise (5) in relation to a substrate (2), whereby, where necessary, printing points (DP) are generated according to predetermined printing data (VD) at raster positions (RP) of a print line (DZ) consisting of microlines (MZ1, ..., MZ8). The printing points (DP) are allocated to a first (DM2) and at least a further, supplementary printing pattern (DM2), whereby one of the printing patterns (DM1, DM2) is generated during each printing head  movement. The printing points (DP) are allocated to the printing patterns (DM1, DM2) alternately microlinewise in such a way that adjacent printing points (DP) in a microcell (MZ1) are contained in different printing patters (DM1, DM2) between the generation of the printing patterns (DM1, DM2) o f a microline (MZ1), the substrate (2) is preferably advanced in relation to the printing head (1). Adjacent printing points (DP) in a microline (MZ1) are thereby generated during different movements of the printing head and by different printing elements (11-1, 11-5). Errors peculiar to individual printing elements and line advance faults are thus distributed very evenly over the printed image.

Title: Stenter frame which saves energy - has injector air jets located in proximity and to suit width of fabric
Inventor: PABST MANFRED
IPC: F26B21/00
Filed: 1992-08-26
Abstract: On a stenter frame the fast moving stretched textile fabric is subjected to a force of warm air. This may be directed from one or both sides, through jets. These are parallel to the fabric, singly or in groups on one side across the width, in suitable brackets at the air circulation side. Typically, the fabric (1) is stretched across the width of the frame and held by grips or pins (2), which are fixed to a lengthwise traversing chain (4) on each side. The injectors (5) concentrate the airflow directly on to the fabric. The air is compressed (6) and fed into a channel (7) which may be flexible. The injectors are connected to this, giving the flow (8), which is reflected (9) upwards, into an enclosure (11). It is recirculated through a heat exchanger (12) into an interior box (10) and through bottom orifices (13) progressively, creating the ambient temperature. ADVANTAGE - The jets concentrate on the face or reverse of the cloth, only to the cloth width, to avoid waste of energy.

IPC: B26D7/08
Filed: 1992-10-13
Abstract: Appts. to cut a narrow strip from a paper web at a papermaking machine, pref. at the drying section, uses a cutter with a recess on the side towards the paper web which forms a tunnel together with the paper web along the direction of travel. A cutter is in the tunnel, at its walls. Pref. the cutting unit is a roller with its axis at right angles to the paper web and at right angles to the direction of paper travel. The roller rotates.
