Inventor: LAMPKA BRUNO
IPC: F24B1/02
Filed: 1985-07-18
Abstract: A tiled-stove insert (10) has, adjacent to its rear wall (18), an intermediate wall (24) and, adjacent to the bottom (20), an intermediate wall (26). Between these, smoke gas flow chambers are formed, which are divided by partitions into two chamber parts lying outside and a central chamber part (52) lying between. Adjoining the two vertical smoke gas chamber parts lying on the outside are horizontal smoke gas chamber parts and situated between these is a central horizontal chamber part (48) which communicates with the vertical central chamber part (52). The smoke gas chambers form a secondary heating device and are passed through by a number of hot-air pipes (54, 56). The new tiled-stove insert is extremely compact and contains the integrated secondary heating device which can be cleaned at any time. The degree of heat utilisation is better by virtue of the highly efficient secondary heating system. <IMAGE>

Title: Method of testing a random-access memory during its operation
Inventor: SCHULZ MICHAEL
IPC: G11C29/10
Filed: 1985-08-23
Abstract: In systems in which breaks in the working sequence between an operating system (BS) and a random access memory (RAM) occur asynchronously, difficulties are encountered when testing its cells during operation. In the case of the test method according to the invention, in a test step concerning a particular group of cells the code word already stored there is taken over into a testing device (PE) and replaced by a test pattern, which after reading back is compared with the original test pattern. Since, if they do not match, there is either a cell defect or the test pattern has been changed by a code word of the higher-priority working sequence, written in in the meantime, the test step is repeated until a match occurs or there have been a number of repetitions greater by one test step than the number of interrupted test steps assumed to be possible as a maximum. When a match is achieved, the last code word provided in the meantime by the operating system (BS) for this group of cells is written in. This test method is suitable for a signalling-converter central section. <IMAGE>

Title: "Least recently used" network without pointer registers and comparators
Inventor: SCHUBERT LUDWIG DR
IPC: G06F12/123
Filed: 1986-01-29
Abstract: In memory management, e.g. in connection with CAM management, old entries must be replaced by new ones. Which entry should be replaced is determined by a so-called replacement algorithm. A particularly powerful replacement algorithm, but one which is expensive to implement, is the "least recently used" (LRU) algorithm, which replaces the entry which has not been used for longest. The invention implements this algorithm with a favourable price-performance ratio. Implementation using counters, a permutation network and chained lists is known. (Patent specification DE 2816838 C2.) The invention solves the problem by construction of chained lists in RAM memories, using a simplified algorithm compared to patent DE 2816838 C2. The simplified algorithm runs in the same way, independently of whether the entry number which is defined as the triggering variable (AK) is the newest (NPO) or oldest (HPO = LRU) entry. This is achieved as follows:   a) replacement of the pointers (HPO), (NPO) by an entry cell which cannot be addressed from (AK), which has a fixed address 'P', and which contains the pointer to the lowest-priority variable (NPO) in (HPS), and the pointer to the highest-priority variable (HPO) in NPS,   b) maintenance of the cyclic termination of both priority sequences at every assignment event,   c) taking the new ...

Title: Anode for electrolytically metallising metal strip
IPC: C25D17/10
Filed: 1987-04-29
Abstract: Soluble or insoluble anodes are used in conventional methods for electrolytically metallising metal strip. If soluble anodes are employed, only a fraction of the coating metal used can be exploited since there is otherwise the risk that the anodes in the finishing cells break off because they are eroded and their cross-section becomes thinner. It is therefore proposed to employ an anode in which the soluble anode sheath 2 having attachment devices 3 are attached to an insoluble anode core 1. A virtually 100% utilisation of the soluble anode material 2 is thereby achieved and the anode fabrication is considerably simplified. The energy costs incurred in the coating process are reduced and the addition of interfering alloy elements to the anode material can be eliminated.
