Title: Process for the production and repair of pump housings for pumps for delivering material containing sand and gravel, and pumps of this kind
Inventor: MEIER GUDRUN
IPC: F04D29/42
Filed: 1983-06-28
Abstract: In pumps which are used for delivering material containing sand and gravel, the pump housing is frequently made of chilled castings, in order to counteract the erosion or damage to the housing which usually occurs. Such erosion can however be neither prevented nor repaired to reasonable satisfaction. Therefore, according to the present invention, the zones of greatest wear loading are determined for different types of pump, and cut-outs (21) are provided, in a region correspondingly widely covering these zones, on the inner wall (103) of the corresponding pump housing (101); matching filling pieces (22,etc.) are then interchangeably and releasably fastened in these cut-outs (Fig.3). These filling pieces (22) preferably consist of hard, wear-resistant material. With different pump types, the zones of greatest wear loading are usually determined at different places; for identical pump types, however, the zones of greatest wear loading usually appear in the same zones, so that a multiple exchange of the filling pieces (22) is also easily possible and thus the lifetime of the housing (101) can be substantially extended. The associated production process shows the procedure for the production or repair of such pumps. <IMAGE>

Patent DE-3339016-A1 (DE)
Title: Forced-feed circulating lubrication process and device suitable for implementing this
Inventor: KNAEBEL HORST
IPC: F16N29/02
Filed: 1983-10-27
Abstract: The invention relates to a process for metering the lubricant flow in, preferably stationary, forced-feed circulating lubrication systems, and a control unit suitable for implementing this process, in which a fixed throttle and a variable throttle are arranged, the passage cross-section of the variable throttle being variable by means of a resiliently preloaded control element as a function of changes in a predetermined pressure difference between the pressures upstream and downstream of the fixed throttle. The circulatory flow has hitherto been controlled as a function of pressure and viscosity or independently of pressure and viscosity. The disadvantage to this is either an unstable control or an over supply of the lubricating points in the case of cold and highly viscous lubricant and an unsatisfactory heat dissipation from the lubricating point in the case of warm and low-viscosity lubricant. According to the invention these disadvantages are avoided in that the circulatory flow is controlled as a function of the viscosity and uninfluenced by the admission pressure in such a way that as the viscosity falls the circulatory flow increases. This corresponds to the true lubricant requirement and the hydraulic return behaviour of the lubricant from the lubricating points of a forced-feed circulating lubrication system between cold starting and operating state.

Title: Method of activating latent defects in memories with memory/insulating layer field-effect transistors which have a floating-potential memory gate
Inventor: ADAM FRITZ GUENTER DIPL PHYS D
IPC: G11C29/50
Filed: 1983-12-14
Abstract: According to the method, a process for producing integrated circuits with memory transistors which each have a floating-potential memory gate (Fg) is interrupted in the stage in which the individual memory gates have not yet been etched out of the conducting layer (2), so that it is possible to apply between the conducting layer (2) and the semi-conductor board (1), which is bonded by means of a heating plate, such a voltage at an elevated temperature that the latent defects of the tunnel insulator layers (It) are activated. In this way, memories which would not have been detected as defective until the final test after an aging treatment are segregated at a relatively early stage. <IMAGE>

Patent DE-3402902-A1 (DE)
Inventor: STEFFINGER KARL
IPC: H01R12/71
Filed: 1984-01-27
Abstract: A right-angled plug-type connector for a printed circuit board connection characterized by a flexible fixing plate being secured in a plate-shaped retaining member to extend at right angles to the retaining member and having a plurality of bores in a pattern corresponding to a pattern of bores in the retaining member to receive contact elements which have a right angle bend. To improve the guidance of the contact elements which extend past a first side of the fixing plate to form contact prongs, each of the bores has a tubular extension which extends from a second side of the fixing plate. The tubular extensions improves the guidance and positioning of each of the prongs to prevent skewing or misalignment during the forming of a plug connection.
Patent DE-3404186-A1 (DE)
Title: Curve-negotiating conveyor belt
Inventor: THOMAS GOETZ DIPL ING
IPC: B65G15/60
Filed: 1984-02-07
Abstract: This invention relates to a conveyor belt whose endless non-tension support element (3) is folded into itself and therefore only possesses a single edge, which is connected to an endless tension element (2). Guiding the conveyor belt through curves without separation of the tension element (2) and the supporting element (3) is made possible in that the tension element (2) is guided, by means of the guide rollers by which it is supported, in such a way that two sections of the tension element (2a, 2b) situated opposite one another on the supporting element (3) cover identical distances during one cycle. Minor differences in the distance covered, caused by differential forces or imprecise guiding, which result in separation of opposite edge sections of the supporting element after a number of cycles when two tension elements which are fixedly connected to the supporting element are used, are compensated for by the folding in and the use of a single tension element after the subsequent cycle in each case. <IMAGE>
Patent DE-3404849-A1 (DE)
Title: Radiant heating system
Inventor: ZORTEA REMBERT
IPC: F24D3/00
Filed: 1984-02-10
Abstract: The ceiling radiant heating system (1) essentially consists of heat exchangers (4) through which a hot medium flows, and also an insulating layer (5) arranged on the rear side of the heat exchangers. The heating medium is fed in and taken out via ducts (2) and (3). The heat exchangers (4) are constructed as absorber plates or flat collectors, as are known in solar energy plants, with a small throughflow passage and a large radiating surface, and can be connected into the heating circuit individually or in groups. Short heating-up and cooling times are thereby obtained, and the radiant action is substantially improved. The radiant action can thereby be concentrated at a desired place. An individual control of small regions to be heated or a grouped heating operation are thus possible (Fig. 1). <IMAGE>

Patent DE-3416645-A1 (DE)
Title: Harness for Jacquard machines
Inventor: BOESCH FRANK
IPC: D03C3/42
Filed: 1984-05-05
Abstract: In a harness cord (1) with a heald (2) and a small tube or tubular elastomeric counterpull (6) for harnesses on Jacquard machines, the connection point between the heald (2) and the counterpull (6) is susceptible to wear and therefore to faults, since this point is exposed to high loads when the harness is in operational use. In order to provide a space-saving remedy for this, an elastomeric intermediate piece (8) in the form of a small tube is slipped on the lower end (5) of the heald (2). Its length (L) amounts to only a fraction of the length (L) of the counterpull (6). Furthermore, its cross-sectional area is larger than that of the counterpull (6). The counterpull (6) and intermediate piece (8) are connected to one another via an inserted pin (9). The harness thus has, at the point particularly susceptible to wear and therefore to faults, a stretching and extending zone embodied by the counterpull (6) and a joint embodied by the intermediate piece (8) in the form of a small tube which alone absorbs the bending stresses caused by the transverse vibrations and, as a result of its relatively large dimensions, can tolerate this stress, even over a long period of time, without suffering damage. <IMAGE>
