Title: Folding device for the outer frames of ground-working appliances
Inventor: BERNHARDT CHRISTOPH
IPC: A01B73/04
Filed: 1987-10-15
Abstract: The invention relates to a folding device for the outer frames of ground-working appliances, especially of appliances for seedbed preparation. The object of the invention is to provide a positively guided folding device which functions independently of the respective mass of the mounted implement section and of the slope gradient. For this purpose, there is arranged between the basic frame and outer frame a pull rope, of which the fastening point on the oscillating implement frame is provided at a distance a above the axis of oscillation of the latter. The pull rope has a minimum length which corresponds to the distance b of the axis of oscillation from the pivot joint plus the distance a between the fastening point and the axis of oscillation. The point of articulation of the pull rope is located on the basic frame below the horizontal plane through the fastening point of the pull rope on the outer frame. <IMAGE>

Title: Integral reactor pipe section for the study of heterogeneously catalytic processes
Inventor: HELMER ARNOLD DIPL ING
IPC: G01N31/10
Filed: 1987-12-14
Abstract: Integral reactor pipe section for studying heterogeneously catalytic processes in chemical research, in particular for obtaining process data in particle layers. An internal tube of different length and diameter and packed with inert particles or catalyst particles has the temperature of its outer side controlled in such a way that exactly defined flow conditions having location-independent rotational symmetry with simultaneously very good heat transfer conditions are thereby achieved. This is carried out by the internal tube fitted into a casing tube according to Fig. 1 being provided on the outside with a rectangular screw thread groove, with the selection of the pitch and the configuration of the thread faces making it possible to match the heat transfer conditions to the requirements of the test. The inflow or outflow of the heat transfer medium occurs tangentially in the flanges via a ring channel at equal cross-section into the screw channel. <IMAGE>

Title: Column press for large eccentric loads and dampening of the cutting shock
Inventor: BALTSCHUN HORST
IPC: B30B1/32
Filed: 1988-03-12
Abstract: The press, which is actuated by means of pressure media has at least two piston/cylinder units which are arranged in the lower part of the press. The press crown is fastened by means of a locking device to the upper piston rods of the cylinder. Releasing the locking device can cause the press crown to move via the rapid-stroke cylinder into the operating position and to be non-positively connected to the piston rods. Relieving of the lower piston surface causes the generation of a pressing force. Control valves can be used to gain control of eccentric loads and dampening of the cutting shock in an optimum fashion in the lower cylinder chamber. The inclined position between the press lower part and the press crown can be kept within narrow predetermined limits. The piston/cylinder units contain the pressing force, dampening, rapid motion, holding-parallel and pulling-off cylinders and the guide and clamp for the press crown.

Title: Method and device for the control and/or monitoring of the drying process of a Yankee cylinder
Inventor: HANNUS HAAKAN
IPC: D21F5/04
Filed: 1988-10-19
Abstract: The invention relates to a method for the control and/or monitoring of the drying process of a web (W) taking place on the Yankee cylinder, the air distribution system of the Yankee cylinder being divided, expediently into three parts, and a computer being used in the method for the control of the process. In the method, a process model is applied which is put forward on the basis of trial runs, on-line measurements and/or drying theory of the process to be controlled or its equivalent. Grade-specific desired value parameters corresponding to the web grade to be run are input from a so-called grade card file or recipe card file. New output values are input into the simulation programme at specific time intervals, measured values of the process parameters obtained from various measuring transmitters of the drying process and, possibly, web samples and coating samples analysed in the laboratory, are used for this. For the purpose of minimising the inaccuracies of the process model, an adaptive process model is applied in the method, for which purpose one specific or several specific parameters in the process are left as variables which are adapted in the correct direction, based on the new output values of the process, in such a way that the process model, as a result, gives values for the measured parameters corresponding to the measured results.

Patent DE-3913728-A1 (DE)
Title: Halftone screen and the use thereof in the reproduction of halftone images and drawings, particularly suitable for textile printing
Inventor: BROBST HUBERT MARCEL
IPC: G03F5/12
Filed: 1989-04-26
Abstract: Owing to the hitherto poor print quality on the fabric, the transfer of a textile design comprising halftones onto the rotary screen-printing screen is rarely carried out using a conventional halftone process. For better print quality, for reproduction true to the original and for improving the efficiency of the time-consuming hand-drawn screen effect and colour separation process used hitherto, a photographic halftone process can now be carried out. The separated screen is characterised in that the brightness value of the halftone is reproduced by different inter-dot separations and not as in conventional processes by different dot sizes. The fine dot is thus sufficiently large for transfer to the screen-printing screen. The characterising feature of the halftone process is that the resolution of a light image is carried out by means of a plurality of different, precisely combined screen arrangements and exposure values thereof. For the first time, it is possible to separate a textile design comprising halftones by a completely photographic method, so that the reproduction on the fabric is optimum.

Title: Control of flow of fluid pumped into patient's body - roller pump with variable position rollers
Inventor: IWATSCHENKO PETER
IPC: A61M5/142
Filed: 1989-07-10
Abstract: The pump for pumping a fluid through a flexible tube (10) into a patient's body consists of a rotating disc (18) which carries six equally spaced rollers (1 to 6). The rollers press the flexible tube (10) against the concave surface of the support (20) and so pump the liq. through the tube. With this type of pump there is a risk of a transient reversal of the flow as each roller passes the edge of the concave surface.  This reversal of flow is prevented by fitting a device which  varies the position of each roller (1to 6) as it passes the edge (20') and also varies the motor speed.  These variations are controlled by a computer. USE - Kidney dialysis etc. @(12pp Dwg.No. 1,11/6)
