Patent DE-2747054-A1 (DE)
Title: Zone heat treatment of zirconium alloy tube - to increase its working life in a boiling water nuclear reactor
Inventor: KIESLER ALLAN JAMES
IPC: H05B6/02
Filed: 1977-10-20
Abstract: Parent patent described the zone heat treatment (ZHT) of a long Zr alloy abject to increase its corrosion resistance in a boiling water nuclear reactor. The object is fed through an induction heating coil for a controlled temp. and time and then through a cooling zone. The temp. of the object in the induction coil is monitored and used to adjust the power supply so the object is heated to 825-1100 degrees C. Improvement is that water at 60-88 degrees C is fed through pipes in the cooling zone to form streams impinging on the outer surface of the object. The water streams may contain air. The pref. ZHT consists of 3-30 seconds at 860-930 degrees C., followed by cooling at 150-400 degrees C/second to 700 degrees C., then at 20-400 degrees C to 500 degrees C, esp. using water at 80 degrees C. Long and relatively heavy Zr tubes can easily be treated so their working life in the reactor is at least doubled.

Title: Permanent storage of radioactive waste bonded in matrix - inside drum equipped with internal mixer blades built from scrap
Inventor: HOFMANN JUERGEN DIPL CHEM DR
IPC: G21F9/00
Filed: 1977-10-31
Abstract: A permanent storage vessel for radioactive waste is for storing the waste bonded solidly in a mixt. typically of cement or bitumen. The vessel contains an insert suitable for agitating the mixt. during the mixing process. More specifically, the insert may be built up from metal waste and scrap, e.g. by welding, or may be made of contaminated or active metal waste. It may be removable after the mixing operation. By using an insert to the storage drum itself the drum is converted into a mixer and no external mixing equipment is required. In this way difficulties arising from contamination of equipment are considerably reduced. The material used for making up the insert is virtually worthless.

Title: Composite synchronisation signal generator for video recorder - controls time constant of single monostable circuit triggered by twice horizontal frequency pulses
Inventor: SCHOLZ WERNER DIPL ING
IPC: H04N5/932
Filed: 1978-07-15
Abstract: The circuit uses a single monostable circuit to generate all the sync. and equalising pulses. A control signal changes the monostable circuit's time constant, which determines the duration of the pulses in the composite sync. signal. The leading edge of all pulses is triggered by a signal having the highest pulse frequency occurring in the composite signal. The monostable circuit is periodically disabled to generate pulses having a lower frequency. The control signal is produced by a shift register. The register is controlled by counting the monostable circuit's output pulses.

Title: Weapon laser for defence against aircraft and missiles - has secondary laser which converts full beam into hollow beam using fusion wire
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H01S3/09
Filed: 1978-10-20
Abstract: The field of application of the weapon laser is extended to include dealing with the hollow folded beam lithium laser of the two-frame disintegrated type. A known folded beam lithium nuclear laser amplifier is started at its back as a secondary amplifier for a full-beam L5 optically pumped, known polycyclic primary light amplifier with 50 to 1000 kJ light energy. A converter changes the beam to a hollow beam which is converted in the secondary laser into a hollow folded beam by fusion of lithium hydride or deuteride wire or other fusion wire, which delivers plasma for pumping the inversion in the laser gas. The primary laser is therefore developed to assist the secondary nuclear as a starting laser and primary amplifier at the starting ramp.

Title: Heat insulating composite door or window frame shank - has open plastics sheath on aluminium tube joined to outside aluminium profile
Inventor: HEUSER VOLKMAR
IPC: E06B3/263
Filed: 1978-12-21
Abstract: An inherently rigid aluminium profile for the weather side and composite plastic and aluminium profile are interconnected to make up the frame shank for a window or door. The assembly includes a load bearing aluminium tube and open-sided plastics sheath. This has ribs and extensions to hold pane-clamping battens, sealing units and anchoring media; also connecting stem pieces on the open side to engage the outside profile. Fixture of the sheath on the tube removes any instability, while the stem pieces are durably held in contact with the aluminium profile. The mechanical properties of aluminium and plastics are effectively combined in a simple structure, for a heat-insulating frame shank.

Title: Switching circuit for data storage system - is supplied from battery and has source divided into two sections linked by single pole switch and shunting diodes
Inventor: BUEHLER KARL
IPC: G11C5/14
Filed: 1979-01-24
Abstract: The switching circuit is for a data storage system where the operating energy is derived from accumulator batteries or the batteries of primary cells. It is possible to switch over from full load operation of the data storage system to a data conservation operation, while only the necessary operating voltage and the current strength are applied for either mode of operation. This is achieved without interrupting the minimum conservation voltage required for serving the stored data. The supply battery is divided into sections (2, 3) linked by a single pole switch (8). The switch connects the battery sections in series. Each battery section is shunted by a diode (11, 12) when the switch is closed. The switch may be a solid state device. On one arrangement, Zener diodes are used to provide a reference stabilisation voltage.
