Abstract: Method of operating a computer (SSP) with an operating system (BS) and a plurality of processes (1, 2 ... N), with a plurality of process memory sections (P ...), in which one of the processes (1, 2 ... N) is stored in each case, and with a system memory (SS), in which the operating system (BS) is stored, which memory for its part stores in each case operating words under at least one operating address (BA ...). For high-speed and strictly monitored and consequently reliable data transfer between a process (eg. 1) and the operating system (BS) and/or between various processes (1, 2 ... N), in at least one of the memory locations (SP ...) of the process memory sections (P ...), that is in special memory locations (SP ...), in each case there is entered initially, instead of a valid operating address (BA ...), only an invalid address, which prevents a direct access to one or more of the operating words stored under the operating address (BA ...) being possible via the process (eg. 1) into which the invalid address is entered. However, in response to a special control signal (SVC), an intermediate memory or intermediate register (R) can overwrite at least one of the invalid addresses, previously entered in at least one of the special memory locations (SP ...), with one or more valid operating addresses (BA ...). <IMAGE>

Title: Circuit arrangement for temperature-regulated electrical heaters or heating apparatuses
Inventor: SPEIDEL VOLKER DIPL ING
IPC: G05D23/19
Filed: 1983-10-11
Abstract: The circuit arrangement for temperature-regulated electrical heaters or heating apparatuses, especially flexible heating apparatuses, is provided with a heating conductor (1), a temperature sensor (2) for detecting the actual temperature value, a desired temperature value transmitter (3), a temperature reference value transmitter (4) and an actuator (5) which controls the current flow in the heating conductor (1) by comparing the actual temperature value Ti with the temperature reference value. Once the apparatus has been switched on, the temperature reference value transmitter (4) prescribes temperature reference value, which is dependent on the selected desired temperature value, is increased above said value and corresponds to an increased pre-heating temperature T1, in a pre-heating phase V, which precedes in time the regulation phase R where the temperature is regulated to the desired value, until the actual temperature value Ti has reached this pre-heating temperature T1. The temperature reference value is increased in the pre-heating phase as a function of the environmental temperature, which is determined from the actual temperature value Ti at the start of the pre-heating phase V, by an extent which increases as the environmental temperature becomes lower. Furthermore, a transition phase Ü is provided between the pre-heating phase V and the regulation phase R, in which transition phase the increased temperature reference value is reduced continuously or in steps to the desired temperature value. <IMAGE>

Title: Position transmitter
Inventor: RAPP WERNER DIPL ING
IPC: H03M1/16
Filed: 1984-02-28
Abstract: In a position transmitter comprising a pulse transmitter (3, 4, 5), which generates at least one pulse with each rotation of a drive shaft (2) by a predetermined fraction of a complete revolution, a rotatably supported code disc (10) is coupled to the drive shaft (2) via a step-down transmission (6 to 9), the scannable coding of which disc, provided in successive sectors of the same size identifies a sequence of absolute position values, one of which is in each case allocated to each sector. The transmission ratio of the step-down transmission (6 to 9) is selected in such a manner that a complete revolution or an integral fraction of a complete revolution of the drive shaft (2) leads to a rotation of the code disc (10) by the angle corresponding to one sector. The pulse transmitter (3, 4, 5) is provided with a marking which generates a signal in each angular position of the drive shaft (2) which corresponds to one of the absolute position values which can be scanned by the code disc (10). An associated evaluating device (18) exhibits an input for the signal and the coding which can be scanned by the code disc (10). <IMAGE>

Title: Closure cap D1
Inventor: RIEMER DIETER
IPC: E04C2/54
Filed: 1984-03-13
Abstract: To maintain the transparency of a twin-web panel, it is necessary to close the interface. It is intended to achieve this with the closure cap D1. Firstly, the closure cap D1 is intended to seal the interface so as to prevent the penetration of dust and water. Secondly, it is necessary for the molecular sieves contained in the cavity of the closure cap D1 to adsorb the atmospheric humidity from the web cavity of the double-web panel. The size of the closure cap D1 can be varied. The crucial point is the principle. The difference in the web cavities is 0.2 mm. Attention has to be paid to this when the size of the closure cap D1 is specified. The cavity of the closure cap D1 is closed by means of a stopper having twenty 0.5 mm bores. As a result, the molecular sieves contained in the cavity are able to adsorb the atmospheric humidity. The molecular sieves of the general formula (R, R2') O.Al2O3.nSiO2.mH2O) (where R' and R denote a monovalent or bivalent cation, for example alkali metal or alkaline earth metal ions, and n and m are molar numbers) have a high adsorption capacity for gases and vapours, for example water vapour, carbon dioxide and methane.

Title: Method and device for retarding and overlapping paper sheets in paper processing machines
Inventor: BRANDT ECKHARD
IPC: B65H29/66
Filed: 1984-03-15
Abstract: Paper sheets (7) are severed from one or more webs (1) of paper by means of transverse cutters (3). Via a conveying section (12) with a normal speed of transport, the said paper sheets (7) reach a slower-running deceleration section (21), where they are retarded by means of a braking roller (29) and are deposited in an imbricated and/or overlapping manner. Optimum deceleration and a uniform overlapping of the paper sheets (7) are achieved by setting a gap dimension (x). After the discharging of unusable paper sheets (7) via the sheet distributing device (9), undertaken at high conveying speeds, first the gap dimension (x) is reduced and, after retardation and overlapping of a predetermined number of paper sheets (7), returned to the original value so that continuous production can recommence. The modification of the gap dimension (x) is achieved by automatically controlling the pressure roller (32) upwards and downwards. <IMAGE>

Patent DE-3424626-A1 (DE)
Title: Method for the error-protected transmission of digital information
Inventor: BLUETHGEN BJOERN
IPC: G11B20/18
Filed: 1984-07-04
Abstract: The technical development of microelectronics has led to it being possible to transfer very large volumes of data within a short time or to store these data over a short or long term in memories with high storage capacity. In this connection, data protection during transfer or also during storage acquires more and more significance. As has been found in practice, information data words including their auxiliary error correction data can be falsified, undetected, due to external influences such as, for example, electrostatic discharges or brief power supply disturbances during the processing or transferring of large volumes of data. Such falsifications may occasionally mean high rejection losses, for example during the production of optically readable digital audio disks. To be able to detect such information falsifications rapidly and reliably, it is proposed to form check sum words (PWi), at least section by section, of the information to be transferred or to be processed, and to check these check sum words for correspondence with check sum words (PW'i) of the transmitted or processed information, formed continuously in an identical manner, and to display the result of the comparison. <IMAGE>
