Title: Method and device for controlling the tape overrun in folding machines
Inventor: GRUEGER CHRISTIAN
IPC: B65H45/12
Filed: 1983-06-18
Abstract: The invention relates to a method and a device for controlling the tape overrun at the first blade folder of a folding machine. The object of the invention is to detect the slip occurring of a sheet between the sheet feed and the first blade folder for a correction of the tape overrun at any desired clock speed and under any desired slip conditions of the machine in order to achieve a high degree of folding accuracy. For this purpose, when the machine is running the phase shift in the movement cycle of a blade folder which is set in a defined manner is determined at the associated movement cycle of the front edge of the sheet within a working clock at the first blade folder of a folding machine for a number "n" of work cycles, the average value is formed and preferably output in cm/per working clock. The deceleration occurring when slip arises is determined in an electronic evaluation device and output as a characteristic variable for the deviation of the setting value of the optimum tape overrun, and the movement cycle of the front edge of the subsequent sheets is changed via an actuation element by controlling the feed time so that the slip is compensated.

Title: Process for the separation, desorption and detection of aliphatic amines contained in air
Inventor: BLOME HELMUT DR
IPC: B01J20/28
Filed: 1984-01-04
Abstract: The invention relates to a process for the separation, desorption and detection of aliphatic amines contained in air. The process is to be assigned to the areas of detection and separation of hazardous working materials contained in air. It has not been possible hitherto to adsorb aliphatic amines contained in air durably onto a solid collection matrix which is a precondition for a reliable separation system or for a hazardous material detection system using sampling devices based on a solid collection matrix. The invention relates to a process which is able, with the use of a silica gel, found on the basis of extensive trials to be suitable, to adsorb aliphatic amines over an extended period. For the sampling system, the invention is supplemented by a suitable process for desorption and a gas-chromatographic separation process using a phosphorus/nitrogen detector (PND) for the detection of aliphatic amines. Applications for the invention are envisaged in the filtering separation devices sector and in the sector of testing and detection processes for hazardous materials in air.

Title: Circuit arrangement for monitoring the tyre pressure of vehicles
Inventor: HAUBNER GEORG
IPC: B60C23/04
Filed: 1984-04-07
Abstract: A circuit arrangement for monitoring the air pressure in vehicle tyres is proposed, in which arrangement measurement inaccuracies due to production and fitting tolerances are to be eliminated. For this purpose, at a predetermined tyre pressure (M1, M2) the measured value (Um) which is then detected is deposited, by actuating a calibration key, during the journey in a read-only memory of an evaluation circuit. By means of the stored measured value, the position of a characteristic curve (K) is determined by means of which curve the cyclically detected measured value (Um) is subsequently converted in the evaluation circuit as a function of the tyre pressure Um = f(p) into a value (p) for the air pressure in the tyre. <IMAGE>

Abstract: The invention relates to the extraction of soil samples (cores) in essentially non-cohesive, water-bearing soil strata. The invention permits with relatively simple means the extraction of soil samples in the form of drill cores using the economically favourable drilling by means of endless hollow augers. The essence of the invention consists in a two-stage drilling method, where work is carried out with a high applied pressure, high torque and a speed of < 20 rev/min for the core extraction and with speeds of > 60 rev/min for conveying the compacted soil located on the helices of the endless hollow auger. To carry out the method, a core barrel 1 is suspended on a rope 4 with a rope socket 3 in between, and a non-sealed film tube 7 is mounted on a sleeve 8, preferably made of PTFE, the length of which corresponds to 1/4th of the length of the core barrel 1, which film tube 7 is drawn off by about 1/3rd of its length over the free edge of the sleeve in the installed position. <IMAGE>

Abstract: The circular-saw apparatus contains a large, motor-driven circular-saw blade by means of which deep cuts can be produced in concrete blocks. The running mechanism (1) contains three wheels (4, 5), of which two are driven and located one behind the other. These two wheels (4) engage in a guide rail (25) which is fastened rigidly on the ground and runs parallel to the slits (37) to be produced.
