Title: Audio demodulator for multireceiver PAL television system
Inventor: SEO YONG-BEOM
IPC: H04N5/60
Filed: 1995-03-08
Abstract: The demodulator includes an antenna (20) which receives television signals from a broadcast station. An intermediate frequency signal is generated. A first oscillator (24) generates three signals at frequencies applicable to different broadcast standards. The intermediate frequency signal is input to a first mixer (23) with one of the signals produced by the first oscillator and the output is filtered (25).  A second oscillator (27) generates a fourth frequency signal in order to convert the filtered intermediate frequency signal using a second mixer (26). A low frequency second intermediate frequency signal is produced and input to a passband filter (28) and amplifier (29), then passed to an FM detector (30) to produce an audio output.

Patent DE-19534035-A1 (DE)
Inventor: BARTHEL WOLFGANG DR
IPC: B65B61/24
Filed: 1995-09-14
Abstract: The invention pertains to a folding box with lining designed for filling to the brim, wherein the base flaps (3,4) have at the crease line joining them to the side wall (1) the same width as the corresponding side wall, to which is connected a trapezoidal strip which is tapered by 45 DEG  on both sides and which in turn is demarcated from a rectangular section of the base flap by a crease line (5) at the short parallel of the trapezoid. Alternatively, it pertains to a folding box with lining designed for filling to the brim, wherein the rectangular base flaps (3, 4), which have approximately the same width as their corresponding side walls (1), have a plurality of closely spaced crease lines (7) parallel to the line at which they join the side wall. Proposed also is a method for filling a folding box with lining to the brim, wherein the filled box, with the contents enclosed by lining and lid, is turned on its head and the base flaps with their height-adjustable creasing are laid squarely on the base of the lining and in this position glued together. This allows folding boxes to be filled to the brim even with contents of variable specific volume. This provides a simple way of increasing the crush resistance of such folding boxes, since the contents of the filled box contribute to bearing the forces.

Title: Power control of induction motor e.g for driving pump for heating systems
Inventor: POEPPEL JOSEF DR ING
IPC: H02P23/00
Filed: 1995-09-26
Abstract: A power controller of an induction motor C, L1, L2 with an auxiliary winding (1,2) provides power control of the motor by means of a recurring digital word, such as from a ring counter (2). The auxiliary winding L2 has tapping N1, N2 and different power levels of the motor are set by the connection of the auxiliary winding or one of its sub-windings by means of triacs T1-T4. Firstly a coarse adjustment of the power to be output by the motor is effected by the selection of a specified power level and at the same time for the fine adjustment a recurring digital m-bit keying pattern is generated by the ring counter (2) so that the motor is operated alternately with the set power level and with a next higher or next lower power level. This permits automatic power regulation.  A microprocessor (3) carries out the coarse adjustment via a drive circuit (1) and at the same time generates the m-bit keying pattern which is stored in the ring counter (2). Alternatively a single triac T1 connected to the main winding L1 may be switched by the drive circuit (1).
