Patent DE-2754963-A1 (DE)
Title: Induction-heating hob unit for cooker - has power stage AC and DC decoupled from main housing to prevent radiation of RF interference
Inventor: GILGE OTTO
IPC: H05B6/12
Filed: 1977-12-09
Abstract: The induction-heating hob unit, for cookers, has an RF oscillator in its power stage and an induction-heating coil. The power stage is a small subunit compared to the rest of the unit and is electrically and capacitively decoupled in the unit's housing. The advantage of this decoupling lies in ensuring that external metal parts of the housing do not act as antenna radiating FR interference. The power stage may be housed in a chassis of material acting as a screen for h.f. oscillations and mounted on insulating supports.

Title: Gas cooled reactor plant in containment building - comprising outer concrete and inner steel shells with space between
Inventor: WIESER RUDOLF DIPL ING DR
IPC: G21C13/10
Filed: 1978-03-21
Abstract: A nuclear power plant comprises a reactor pressure vessel contg. a gas-cooled reactor. The pressure vessel is housed in a containment comprising a generally cylindrical lower part and hemispherical top dome. This containment consists of an inner shell of steel of the above shape and an outer shell of similar shape at a certain distance, esp. >=0.5 (3-6)m from the inner steel shell. This outer shell is of concrete. Pref. the inner face of the concrete shell is plastics-coated. the space between the two shells may be kept at sub-atmospheric pressure during operation of the reactor. It may contain a series of access platforms or galleries mounted on separate support columns. This space may also contain a lift shaft, optionally certain plant items. A crane is pref. mounted above the reactor pressure vessel. An access door for introduction of components may be provided in the steel shell. Considerably shortened construction time due to the greater ease with which testing of the steel shell can be carried out during construction and due to the use of slip-forming for the concrete outer shell. In the hypothetical case of an aircraft crashing on the outer shell, the leak-tightness of the inner steel shell will still not be impaired. In addn., protection may also be afforded to those plant items which are incorporated inside the concrete shell.

Title: Opto-electronic touch button for keyboard - depends upon operators finger to change total internal reflection in glass touch block (SW 3.7.78)
Inventor: BERGSTROEM ARNE
IPC: H03K17/96
Filed: 1978-06-03
Abstract: The opto-electronic touch-button has a rectangular glass block (5) with a contact surface (6). A light source (1), e.g. l.e.d., directs a light beam into the block in such a way that it is reflected by total internal reflection at the contact surface and reaches a photo-detector (3) located on the other side of the block. When the user places his finger on the contact surface the conditions for total internal reflections are altered and the amount of light detected changes, which results in a change in the detector's electrical output signal. The detector is arranged so that it is not influenced by external light sources.

Title: Frequency conversion circuit using one transistor stage - with adjustable RC resonance loops in input and output stages to convert from high to low frequency or vice=versa
Inventor: ELFENBEIN WALTER
IPC: H04B1/66
Filed: 1979-10-12
Abstract: The basic circuit consists of an input stage with an RC resonance loop of variable frequency with an output from a centre-tapped capacitor being applied to a voltage divider and then to the base terminal of a transistor, with another resonance loop in the emitter-collector output circuit. The circuit functions either as a frequency converter for 10.7 MHz input to 2.14 MKz output, or vice-versa. The system enables an FM input with a high frequency range and wide band width to be converted into a lower frequency range and narrower band width, esp. for storage on a tape or disc recording device. The advantage of the circuit is that it may be used in reverse with different values of the resonant loop in the input and output stages.

Title: Opening device for over-current switch - converts magnetic energy of monitored current into potential energy for release to open contacts
Inventor: TAYEFEH-EMAMVERDI MOHAMMAD DIP
IPC: H01H77/10
Filed: 1979-11-12
Abstract: The device converts a given energy for separating the contact pieces unreduced, ignoring frictional losses, into kinetic energy of the contact pieces and/or stores the energy as potential opening energy for separating the contact pieces. The magnetic energy of the monitored current is converted into potential mechanical energy, which on reaching a threshold of a release quantity, preferably of the monitored current, is converted into kinetic energy for the contact pieces. Alternatively the potential opening energy may be converted into kinetic energy of the contact pieces directly.
