Title: Composite melting conductor having a plurality of constriction regions, and a method for its production
Inventor: SCHULTZ LUDWIG DR RER NAT
IPC: H01H85/055
Filed: 1984-01-18
Abstract: The composite melting conductor for a fuse device, especially for a semiconductor fuse, has constriction regions between a plurality of conductor pieces containing a more base metal, which constriction regions consist of a comparatively more noble metal and are formed from a thin conductor element, which is in the form of a strip, extends in the direction in which current is passed and is connected outside the constriction regions to the conductor elements consisting of the more base metal. This composite melting conductor is intended to require only a comparatively small component of the more noble metal and at the same time to be simple to produce. To this end, the invention provides that the conductor element (10), which is in the form of a strip and consists of the more base metal, is mechanically firmly surrounded on each of its two ends (23, 24) by a conductor element (13 or 19 respectively) consisting of the more base metal. At least a portion of the more base metal of the conductor elements (13 to 19) is preferably provided with a layer consisting of a material which constrains oxidation. <IMAGE>

Title: Bobbin for the reeling of skein-like material and method of manufacture of the said bobbin
Inventor: SCHMIDT KARL-GUENTER DIPL ING
IPC: B65H75/14
Filed: 1984-04-06
Abstract: The invention relates to a bobbin for the reeling of skein-like material, which bobbin has lateral discs or flanges, which are creased or corrugated for reinforcement. Each corrugation or crease is formed by individual segments (25) which are of the same shape and dimensions. The individual segments (25) are placed next to one another in a row in the circumferential direction, leaving a gap (33) at the joints if necessary and are fixedly connected, especially welded, to the running mark (3 or 4) and the cylindrical core support (5). The lateral discs may also consist of two sets with segments of the same shape and dimensions in each set. The individual segments can be produced in each case with great accuracy and can be precisely allocated to one another, so that the points to be welded once the segments have been lined up next to one another in a row are clearly determined. By these means, welding robots can be used in welding, which results in uniform products and a saving of production costs. <IMAGE>

Patent DE-3429405-A1 (DE)
Title: Operating procedure for a heat pump
Inventor: BAUMGAERTNER MANFRED DR
IPC: F24D19/10
Filed: 1984-08-09
Abstract: The invention relates to an operating procedure for a heat pump which supplies, as a function of a thermal requirement, at least two thermal consumers (3, 5) having different priority stages, and is fitted with a high-pressure pressostat (7) which in the case of overpressure in the cold circuit of the heat pump switches the latter off. After the high-pressure pressostat (7) has responded in the event of a thermal consumer being supplied, the thermal requirement of this thermal consumer is suppressed for a prescribed time. Consequently, even thermal consumers having a low priority stage can be supplied when the high-pressure pressostat responds continuously in a higher priority stage. <IMAGE>

Title: Driving element
Inventor: KRUSCHE ARNOLD
IPC: F16G1/28
Filed: 1985-04-16
Abstract: If driving elements designed as toothed belts are to be used with an overlap in certain areas, then they must run adjacent to one another in these areas, requiring a deflection out of the common centre plane. To avoid the occurrence of such deflections, it is proposed that the ends of the toothed belts which are to overlap in use be designed to be half as wide as the toothed belt.
Patent DE-3519990-A1 (DE)
Title: Thermal printing head
Inventor: WESSEL GERHARD
IPC: B41J2/345
Filed: 1985-06-04
Abstract: For satisfactory printing, high-performance thermal printers require initial heating above the normal ambient temperature since the time available for heating up the heating elements is very short. Otherwise, a very high degree of residual heat, which must be conducted away as quickly as possible, remains due to the high heating-up temperature. For this purpose, the invention provides, for a thermal printing head with a plurality of heating elements arranged in a row on a substrate (7), a substrate carrier (1) which has a channel (2, 3, 5) directly under the substrate (7) in the region of the heating elements. The said channel (2, 3, 5) is arranged in the circuit of a circulation system of a fluid or gaseous medium. The circulating medium is kept at a constant temperature via a control device, which temperature corresponds to the provided initial heating of the heating elements. <IMAGE>

Title: Method for determining the residual power (afterpower, afterheat) of a nuclear reactor
Inventor: SCHOEPE WOLFGANG
IPC: G21C17/00
Filed: 1986-02-17
Abstract: The instantaneous residual power of a nuclear reactor which is important for cooling in emergencies (accidents), is obtained as the sum of the residual powers of the fuel elements. For this purpose, the burnup characteristic of the latter is determined from the measurement (1), repeated at time intervals, of the neutron flux density. It is also possible during the determination to take account of the regime of the nuclear reactor and of the fuel element location in the core. The residual power is advantageously indicated in the power station control room. <IMAGE>

Title: Heterostructure laser

Patent DE-3608797-A1 (DE)
Title: Heat exchanger for the ultrarapid, low-loss heating and cooling of fluids, in particular in hot-gas engines, Stirling engines and refrigerating machines
Inventor: KIESSLINGER RUDOLF
IPC: F02G1/055
Filed: 1986-03-15
Abstract: A main problem, e.g. in Stirling engines, is the necessity for rapid heat transfer between the working gas and heat source or cooling surface. This problem is solved by this invention with the aid of a rotor disc (B) which is occupied in a suitable way by thin lamellae (D) and which rotates rapidly in a narrow air gap (C) and in the process drives the molecules of the working gas through the air gap, i.e. along the heat exchange surfaces (E) (Figs. 1 and 2). A heat-insulating boundary layer cannot form on the heat transfer surfaces, because just as it is formed it is "peeled off", as it were, by the lamellae acting like a squeegee (doctor blade). The intrinsic volume of this "circulating pump" is negligible by comparison with the working volume of the working gas, and the power requirement is slight. As demonstrated in trials, the total working gas is thus brought within a very short time into close contact with the heat exchange surfaces. This permits higher speeds, i.e. a higher power per unit of weight, in conjunction with a lower temperature loss in the heat transfer, i.e. a better efficiency of the machine. <IMAGE>
