Title: Magnetically journalled twisting ferrule - reducing eddy currents and heating effects by varying air gap geometry
Inventor: BRICHTA FRANZ DIPL-ING
IPC: D02G1/06
Filed: 1970-12-12
Abstract: Twisting ferrule journalled in contactless manner by magnetic bias whic constrains it against axial displacement and forces it radially into contact with driving rollers, is prevented from overheating by reducing the eddy current formation in the magnet through reducing the air gap and increasing the cross-sectional area of the gap, the magnet being formed by a core having a roof-shaped end facing the ferrule and a housing completely surrounding the core and having a complementary roof-shaped end, the ends conforming to the periphery of the ferrule.

Patent DE-2116616-A1 (DE)
Title: Ultra centrifuge head insert - with cells shaped to permit increased speeds without affecting life
IPC: B04B5/04
Filed: 1971-03-31
Abstract: In ultra centrifuge heads, the cylindrical shape of cells and their inserts, limiting speeds to about 60,000 r.p.m., is varied to a basically triangular shape with rounded corners. The triangle sides may be straight or of a curved geometrical outline. This new shape permits increase of centrifuge speeds by about 15% without affecting life, since, it offers more strength, better distribution of forces, less material strain by respectively greater wall thickness between cell and head circumference, larger supporting area, shifting centre of gravity toward the head axis and reduced weight.

Title: Receiver for FM radio links - uses reduction of channel cross-modulation by adjacent channels
Inventor: SEIBT EDUARD DIPL-ING
IPC: H04B1/10
Filed: 1973-08-22
Abstract: Selection is increased only when input power is low. Two band-stop filters are tuned to frequencies on both sides of the passband of an IF bandpass filter, to which diodes are added which strongly damp the band-stop filters when the input signal is high, and remove the damping when it is low. The band-stop filter L-C ratio is such that the propagation time distortion is symmetrical. The diodes in series with a capacitor are in parallel with the band-stop filters tuned to the sum or difference of the useful channel and of the adjacent channels centre frequencies. For automatic gain control the current is derived from the gain control voltage.

Title: Code-word detector - detects synchronisation or address word in fast serial transfers
Inventor: BONNELYCKE BYRG DIPL-ING
IPC: H04W88/02
Filed: 1973-09-08
Abstract: The detector may be constructed entirely in integrated circuits and is particularly suited to transfer rates of 100M bit per second and over. The bits entering the shift register are compared at bit rate with the bits of the code-word from a generator using the comparators. Each comparator output is passed to a counter. The counter is triggered by pulses at bit rate and its output is read out by a multiplexer which is stepped at bit rate so that only the appropriate bit in the n bit code-word will be checked at each step. The second multiplexer is used to step round at bit rate after the check resetting the counters. The shift register may be made a ring counter to recirculate the code-word when it is detected.

Abstract: The separate colour masters are prepared using a special camera in which the film is located by either an accurately defined edge, or on alignment studs. The matrix preparation table has a movable trolley to which the separate masters are attached using a mounting plate. Adhesive is applied to the underside edges of the master and the plate is lowered onto the mounting base when the trolley is in the selected position. The position co-ordinates are then stored so that subsequent colour masters can be accurately located on the different colour matrixes without having to reset to special locating studs fitted to the matrixes.

Title: Battery driven clock voltage circuit - is for energising time or date display using fluid crystals or light-emitting diodes
Inventor: KELLER HANS DIPL-ING
IPC: G04G19/08
Filed: 1973-10-19
Abstract: The circuit provides a voltage which is greater than that across the clock battery. The clock has a quartz crystal connected in an oscillator circuit, which is connected to a motor drive circuit via a frequency divider. The motor winding also acts as part of the voltage converter for obtaining the increased voltage, the pulse duration of the voltage converter pulses being less than the duration of the current pulses through the motor winding. Pref. the latter forms part of a second oscillator circuit whose-frequency is determined by the inductance of the motor winding or by a separate capacitor.

The egg container is designed to move in and out like a drawer and is held in the housing against spring-force by a pawl mechanism which is triggered by the boil-dry switch which is actuated at the end of the cooking time when the water has boiled away. The water measuring device forms the cover or lid for the egg boiler and a steam pipe leads from the container into the measuring device. The control setting mechanism has a counter disc which acts on a piston rod and piston in a measuring cylinder in the water control device which has a supply valve fed from the water supply container and an outlet valve opening into the container.
Patent DE-2360715-A1 (DE)
Title: Magnetic tape unit - has means for automatic locating of specific tape positions
Inventor: SCHOLZ WERNER DIPL ING
IPC: G11B15/00
Filed: 1973-12-06
Abstract: Markings printed on the tape represent numbers, which are read and compared with a manually input number in an evaluator. If the numbers correspond, the fast mode is stopped. By dispensing with manual operating means for the fast mode, the evaluator is designed, so that shortly after the input of a number, it automatically emits a switching-on voltage for the fast mode. The switching-on voltage is automatically produced approximately 1.5 seconds after a number is received. The switching on of the fast forward or reqind and the stopping of the fast mode takes place solely by controlling the motor current.
