Title: High tension transformer body - has divided secondary winding chamber for X=ray generator
Inventor: WACH PAUL PROF DIPL ING DR TEC
IPC: H01F27/32
Filed: 1977-12-20
Abstract: The secondary winding of a high tension transformer for use in generating X-rays (Ua) is divided into two parts by splitting the coil and locating it into a pair of unequal chambers separated by insulating boards in the axial coil direction. The boards have passages which are hollow and continuous which run along a surrounding zone to the bottom of the closest chamber. The unequal chambers have an active right section of coil so the depth and height of the coil varies according to required tension.
Patent DE-2801401-A1 (DE)
Inventor: KREBS PETER DIPL ING
IPC: H01H33/915
Filed: 1978-01-13
Abstract: The circuit breaker housing (11) is divided by an electrically insulating separating wall (12) into an extinguishing chamber (13) and into an expansion chamber (14). A stationary contact (15), having a consumable electrode (17) supported in front of it, is arranged in the extinguishing chamber (13). A moving contact (33), which is constructed as a nozzle tube, is guided displaceably through the separating wall (12) and can be moved axially into engagement with the stationary contact (15). In addition, the stationary contact (15) encloses an intermediate electrode (27), which is electrically insulated from said stationary contact (15), projects beyond the consumable electrode (17) and, in the switched-on position, engages in the moving contact (33). During the switching-off stroke, two arcs are thus produced successively, the first (D) leading to a pressure increase in the extinguishing gas which is present in the extinguishing chamber (13), which extinguishing gas then flows out through the moving contact (33) into the expansion chamber (14), thus blasting the second arc (l). In order to prevent the base of the first arc (D) commutating back on to the stationary contact (15) and in order to make the circuit breaker suitable for a wider range of switching-off currents, the extinguishing chamber (13) is connected to a pump space (22) in which a spring-loaded pump piston (24) is displaceably supported, which can be displaced by means of the moving contact (33) into its original position, during a switching-on stroke, against the spring influence. In addition, the length (b), which projects beyond the consumable electrode (17), of the intermediate electrode (27) corresponds at least to the axial distance (c) from its free end (31) to the free end (39) of the moving contact (33) in the switched-off position. <IMAGE>

Patent DE-2911264-A1 (DE)
Title: Electronic organ loudness correction circuit - varies loudness over each octave to avoid jumps between octaves using capacitor and resistor
Inventor: BOEHM RAINER DR
IPC: G10H1/12
Filed: 1979-03-22
Abstract: In an electronic organ register, the notes of upper octaves are generated at a higher level than low octaves to compensate for the high note attenuation of subsequent tone-forming filters. If the level is constant over an octave, an objectionable jump in loudness occurs when passing from one octave to another. This is corrected by inserting a capacitor and a resistor in series with each octave output to raise the level smoothly from the bottom to the top of the octave. The capacitor may be omitted from the lowest octave, for which little compensation is needed. Compensation permits filters with a steeper cut-off slope to be used, with the added advantage of better suppression of key-clicks.
