Title: Water vessel, filling lever indicator - has body open towards bottom and with movable displacement member
Inventor: KEIELS PETER
IPC: A01G27/00
Filed: 1979-08-24
Abstract: The filling level indicator is for a vessel for the long-term watering of pot plants.

Patent DE-3001353-A1 (DE)
Title: Hot duct esp. for steam has insulation jacket - of double-walled metal casing resting on shoulder of duct with freedom to expand
Inventor: KOERDT REINHOLD
IPC: F16L59/14
Filed: 1980-01-16
Abstract: Vertical duct for a hot medium, typically gas or steam consists of a pipe with external insulation in an annular space of a double walled metal casing surrounding the pipe coaxially. Top and bottom closures of the casing are both formed of conical plates (with upward conical taper); the lower conical plate rests of a shoulder formed by the junction with the main pipe of an additional, outer pipe in the region below the conical insulating casing. The close fit of the conical tapered plate on this shoulder forms a seal to the small annular gap between outer face of pipe and inner face of insulating casing. In a pref. embodiment the lower conical plate is welded to the inner and outer walls of the insulating casing and also welded to the shoulder; the upper conical plate is welded only to the inner casing wall and forms a sliding fit with the outer casing wall. In this region, the cylindrical part of the upper conical plate may be coated to prevent friction welding at this joint. For any hot vertical duct, typically a gas or steam duct, esp. in a nuclear plant. The insulating jacket can be completely prefabricated and is easily mounted by pushing it onto the duct. The insulating effect is not adversely influenced by "chimney convection", because the lower end of the gap between casing and pipe is sealed by the conical plate. Uses include in steam generators of conventional or nuclear power plants, esp. as a live steam duct. The duct would be mounted on the top closure (or double closure) of the vessel.

Title: Recovering logic levels from NRZ code - using looped phase regulator in VCO input
Inventor: DOUVERNE EGON ING GRAD
IPC: H04L7/033
Filed: 1980-05-06
Abstract: A circuit comprises an input for the non-return-to-zero signals to be processed, an inverter for producing inverted signals, two NAND gates with one input connected to the signals and other inputs connected to the outputs of a D-type flip-flop. The shaped clock pulses for the same derive from a v.c.o. controlled by an operational amplifier having an R-C filter loaded input which includes the combined output from the NAND gates in a feedback loop. As a result, a self-adjusting frequency for the clock pulses is obtained, whose leading edge has a phase relationship with the leading edge of the input signal favourable for the strobing of the signal logic levels, and therefore for the conversion of the NRZ code into standard binary code.

Title: Thermal shock resistant oxygen detector for engine exhaust gas - has zirconium oxide electrolyte tube with specified ratio of area to vol. in exhaust gas
Inventor: WATANABE TETSUO
IPC: G01N27/403
Filed: 1980-05-27
Abstract: O2 detector for measuring the O2 partial pressure in engine exhaust gas uses a solid Zr oxide electrolyte tu be, which is closed at one end and has inner and outer electrode coatings, the inner electrode being in contact with a reference gas, whilst the outer one is contacted with the exhaust gas by placing the closed end of the tube in the exhaust pipe. The ratio of the external area of the detector pt. placed in the exhaust gas to its vol. is min. 10 (cm2/cm3) and the outside dia. over the entire length of the detector pt. is max. 6mm, so that the Zr oxide electrolyte is protected against damage due to a sudden exhaust gas temp. change.

Patent DE-3023861-A1 (DE)
Title: Pulse generator with adjustable pulse shape - produces linearly rising pulses by multiplying pulse and ramp
Inventor: BARTH HELMUT DIPL ING
IPC: H03B9/12
Filed: 1980-06-26
Abstract: A pulse generator produces a square wave signal (1,1') of width, ta, and mark-space ratio ta/tb. The output signal is fed to an inverter (Lzg) whose operation is controlled by a timing unit (Stell) which also controls the timing of the generator. Thus, the inserter produces an output of pulse of width tp' when tp' is less than or equal to ta. Its output is fed to a mixer. The generator output is also fed to a negative-going transition detector which produces a very narrow pulse of width, ta, in response to an input. This output is fed to a low pass filter (komm). A linear amplifier (Video) provides a second input (4,4') to the mixer. The amplifier receives inputs from either the low-pass filter or a ramp generator (Rampe) via switches (3,3'). The ramp generator receives inputs from the pulse generator and the timing circuit. The mixer output is fed via two amplifiers (U,I) to a subsequent load (Last). The invention is particularly useful in supplying energy for input oscillators.

Increasing CO2 partial pressure gives an increase in conversion and selectivity; increasing H2 partial pressure may have the opposite effect. The solvent may be non-polar or pref. polar. Pref. solvents are N heterocycles contg. oxygen, partic. N-methyl-pyrrolidone (III). The ratio by wt. of (d):(II) is 0.5-5:1 (1.5-3.5:1).

Title: Caravan/motor home with foldable, rigid canopy and integrated tent walls
Inventor: HARNACK DIETER
IPC: B60P3/34
Filed: 1981-06-30
Abstract: Caravan/motor home with a foldable, stable canopy built on laterally and poles and tent walls integrated therein. By virtue of this arrangement, a stable, weather-proof canopy is ensured which, including the poles and tent walls, can be put up and taken down in a quick, uncomplicated and problem-free manner. The necessary poles are movably attached in the canopy and on erecting the canopy automatically fall into their prescribed positions. Likewise, the tent walls, attached movably in a manner such that they cannot be mixed up, fall into their hanging arrangement where they are then joined together by zip fasteners and fixed to the vehicle by press studs or other fixing means. The entire construction makes camping possible in any weather, i.e. also in winter, particularly by virtue of the problem-free, quick erection of the canopy, as a result of which the rigours of the weather can be kept away from the space in front of the vehicle. The stable tent canopy is resistant to loads caused by the weather, in particular snow loads. From the above it is apparent that searching for pole parts is avoided and also that the tent walls assume their positions in a manner such that they cannot be mixed up. <IMAGE>
