Title: Nip pressure measuring device for rolls and gripper systems
Inventor: PREIS HARALD DIPL ING
IPC: B30B15/00
Filed: 1993-04-28
Abstract: The nip pressure of two rolls with line contact or of two closed gripper jaws is intended to be measured exactly and reproducibly. In order to increase the measurement accuracy and in order to be able to produce the measurement element [1] as simply as possible, the nip pressure is not intended to be converted into a mechanical intermediate variable but to be able to be measured directly electrically. To one end of a sheet metal strip [2] there is bonded or fitted a measuring element which is pressure sensitive and is thin enough to be able to be pushed in between the rolls or the gripper jaws. The sheet metal strip is provided with a stop element [3] which ensures that at each new setting the nip pressure acts on the same location of the measuring element. The measured value is reproduced as a numerical value on a display instrument. This numerical value is set once again in the case of new settings in order to achieve the same nip pressure. A principal field of application of the nip pressure measuring device is the setting of rolls for inking or the gripper jaws for paper transport in printing machines. <IMAGE>

Title: Method for burning particulates in the exhaust gas of an internal combustion engine by means of microwave energy
Inventor: ZIMA PETER DR ING
IPC: F01N3/028
Filed: 1993-06-23
Abstract: The invention relates to a method for burning particulates in the exhaust gas of an internal combustion engine using microwave energy by passing the exhaust stream through an electromagnetic microwave field of high energy density, the combustion of the floating particulates taking place in the region of the high energy density. In order to manage with a relatively low expenditure of energy to build up the microwave field, the invention proposes to use a microwave field with a frequency of from 5 to 10 GHz since the inventors have observed that the radio-frequency energy is absorbed several times better by the particulates in this frequency range than in the case of the customary frequencies. This makes it possible to achieve the self-ignition temperature of the particles to be burned even when a relatively low energy density is employed.

Title: Vehicle IC engine exhaust catalyser deterioration detector - increases feedback control value for engine air=fuel ratio when catalytic converter deterioration is detected
Inventor: TOYODA KATSUHIKO
IPC: F01N11/00
Filed: 1993-08-20
Abstract: The detector uses two exhaust gas sensors (82,84) incorporated in the engine exhaust line (6) in front and behind the catalyser (24), coupled to a regulation stage which evaluates the sensor signals to detect a deterioration in the catalyser and adjusts the air/fuel ratio of the engine. The regulation stage incorporates a verification function allowing the feedback correction of the air-fuel ratio to be increased relative to its normal value when the catalyser deterioration is indicated, with a response delay time which is corrected in dependence on the engine load and the exhaust gas temp. ADVANTAGE - Allows catalyser deterioration detection to be combined with feedback regulation for engine air/fuel ratio.

Title: Method of programming a microcomputer circuit as well as a microcomputer circuit designed for this
Inventor: BAACKE PETER
IPC: G06F12/06
Filed: 1993-09-21
Abstract: The present invention provides a method by means of which a microcomputer circuit 2 having a first, non-volatile memory device 4, a second memory device 6 and a processor 8, such as are used in a very wide variety of technical fields, can be programmed and reprogrammed in a simple manner. The fact that the first and second memory devices are optionally defined as program and data memories ("normal state") or, conversely, as data and program memories ("programming state") means that it is possible temporarily to store in the second memory device 6, via an interface device 10, a new user program from an external apparatus 16, and then to relocate (re-store) the said program into the first memory device - the non-volatile program memory in the normal state of the microcomputer circuit 2. Conventional microcomputer circuits can be converted with little outlay for the method according to the invention. For this purpose, it is merely necessary to connect a selection logic circuit between the microprocessor or microcontroller and the two memory devices. <IMAGE>

Title: Coffee machine
Inventor: SCHLECHT ULRICH
IPC: A23F5/26
Filed: 1994-03-16
Abstract: A method for automatically preparing a prescribed quantity of a coffee drink from a prescribed quantity of ground coffee and a prescribed quantity of hot water which corresponds to the latter is described, the finished coffee drink being accommodated in a supply container and being drawn off therefrom in a concentration corresponding to the drinking strength. In order to be able to draw the coffee drink from the supply container even during the coffee drink preparation cycle, it is proposed that only a proportion of the quantity of hot water prescribed for the production of the hot drink be guided through the ground coffee for extraction and that the rest of the hot water be allowed to flow into the supply container by circumventing the ground coffee at the start of the preparation cycle. The respective proportions are determined in such a way that the coffee drink is of drinking strength in the supply container while the hot water is being fed and the supply of hot water is terminated before the concentration of the proportion which has flown through the ground coffee falls below drinking strength. <IMAGE>
