Patent DE-2638165-A1 (DE)
Title: Used fuel element container has boron shielding panels - sandwiched in double wall possessing outer compensating folds
Inventor: KRIEGER FRIEDRICH
IPC: G21C19/40
Filed: 1976-08-25
Abstract: A chamber or receptacle for used nuclear fuel elements comprises an inner and outer shell with a large number of sintered boron panels between them to provide shielding. The shells are welded together at their upper and lower ends. The upper and/or lower end of the outer shell is shaped as a compensator (or bellows). The considerable differences in temp. between the inner and outer shells are compensated by constructing the outer as a bellows. This prevents distortion of the container.

The struts, posts and supports comprise rectangular hollow profiled rods or tubes which can slide inside one another.
Patent DE-2643207-A1 (DE)
Title: Highly specific, indirect immunoassay - using antibody fragments unable to fix complement, for determn. of antigens
Inventor: SEDLACEK HANS-HARALD DR
IPC: G01N33/563
Filed: 1976-09-25
Abstract: An indirect method for quantitative and qualitative analysis of one partner in an immulogical reaction uses in place of the antibody molecules themselves, their fragments (I) devoid of the Fc portion. (I) are thus unable to fix complement. Other, opt. labelled Fc-fragments can be added which are specific for (I). Pref. an excess of (I) is avoided so that separation of the reaction components is unnecessary. Pref. (I) are F(ab)1 or F(ab)2 fragments and one reaction component can be present in cytoplasm, cell membranes, cell nuclei or tissue. Used for assaying all types of antigens using e.g. the anti-globulin test, the indirect test, with complement or the 'sandwich' test. By removing the Fc portion non-specific binding is minimised so that specificity is improved without loss of the high sensitivity typical of indirect methods.

Patent DE-2649872-A1 (DE)
Title: Thermal pump producing useful heat or cold - uses ice produced during winter operation to cover summer cooling demand
Inventor: ZIPP ALBERT
IPC: F25B29/00
Filed: 1976-10-29
Abstract: The heat pump uses stored ice produced during the winter operation to cover the cooling demand during the summer. The plant consists of a conventional heat pump system, where the reject heat of the compressor produced on the condenser is used to produce hot water for heating purposes. The necessary heat for this part of the cycle is drawn in form of latent heat liberated during the solidification of a considerable quantity of water in a tank. The ice thus produced is stored in a bunker for future use. The ice production with subsequent storing takes place at outdoor temperatures of +3 deg.C to 18 deg.C. If the outdoor temp. is above +3 deg.C and the bunker storage capacity is reached, part of the stored ice is melted down by introducing relatively warm outside air into the bunker. Towards the end of the heating season the ice quantity in the bunker is being stored only, as the number of days with temperatures below 3 deg.C steadily decreases.

Title: Semiconductor prodn. process using locally limited heating - involves electromagnetic irradiation in specified pulses through mask
Inventor: KRIMMEL EBERHARD F DR
IPC: H01L21/265
Filed: 1977-02-09
Abstract: The local limited heating of small regions in a semiconductor substrate is attained by electromagnetic irradiation. The latter is applied to the substrate in individual irradiation pulses through a mask. The pulse duration is kept below several milliseconds, and the irradiation energy exceeds 0.1 Joule per cm-2. The mask regions which cover the substrate sections not to be irradiated, are of material having several times greater reflection coefficient for the applied radiation than the substrate material. The mask material may be electrically conductive. A suitable layer, applied to the substrate surface, may be used as the mask. When a deposited layer is used for masking purposes its material may have a many times higher absorption coefficient than that of the substrate.

Title: Individually and group controlled facade venetian blinds - have scanners with two switching levels directly and indirectly engaging relays
IPC: E06B9/32
Filed: 1977-04-14
Abstract: The control system is for electric-motor-operated venetian blinds. There is a motor for each blind, and group control for a group of blinds, together with facade control for all the motors for a facade at the same time. The individual control units are mounted parallel in a direct control circuit for a group, and their scanners can be bridged by switchgear devices activated by the group control, and disengaged by briding the scanners of the direct circuit. There are diodes in the bridging leads, to effect mutual uncoupling relative to other individual controls as in the main patent. The scanner has two switching levels. The first level directly engages relays, while the second level indirectly engages the relays via a time storage unit. This combines convenience of controls with a high degree of reliability.

IPC: A61M13/00
Filed: 1977-06-15
Abstract: The automatically operated snuff mixer and dispenser has an electric motor which rotates an eccentric drive disc to operate an air pump. A warning device is then actuated to indicate to the user that the device will then operate to eject snuff from a delivery tube. A selectro control enables the quantity of snuff to be deliverd, and also the mixt. to be preselected. This uses a timing device to control the delivery. Also, a selected quantity is subjected to electromechanical vibration to mix the substances. These are then delivered by a gaseous flow whose strength and duration can be determined. The pump forms part of the ejection system.

Title: Repairing worn crankshafts by deposition welding - on machine with automatic guidance system for submerged arc welding burner
IPC: B23K9/04
Filed: 1978-04-13
Abstract: The damaged and/or worn zones of the crankshaft are built up by submerged arc welding, and the repaired zones are then heated to ca. 500 degrees C, followed by slow cooling, to eliminate internal stresses. Grinding of the repaired zones is next employed to obtain the required dimensions. The pref. welding machine uses a headstock and tailstock to rotate the horizontal crankshaft while an automatic guidance system is employed to move a sliding pillar longitudinally along the shaft. The pillar carries a spool of welding wire fed to a burner driven vertically and horizontally to deposit the wire on the damaged zones. The pillar also carries a powder hopper for submerged arc welding. Deposits have high shear- and fatigue-strength and adequate hardness, and without the risk of cracks in the deposit.
