Patent SE-7502293-L (SE)
Inventor: ARTER N K
IPC: G11B27/13
Filed: 1975-02-28
Abstract: An elongated magnetic tape has a pair of longitudinally extending servo track areas, one of which is closer to the longitudinal center of the tape than the other. The lateral space intermediate the servo areas receives data signals, while the space between said one servo area and one edge contains identification and address signals. The tape is particularly adapted for use with rotating head recorders having two gaps on the rotor, with an intergap distance slightly greater than the lateral extent of the servo areas. A recording or write gap precedes an immediately trailing reading or recovery gap. When the rotor gaps pass the one edge in the one servo area, the write gap senses the servo track; while the read gap senses the identification signals. The arrangement is such that prior to the time the write gap reaches the data recording area, the read gap has sensed the identification signals. In a similar manner, when the gaps are leaving the data signal area, the write gap is sensing the other servo area; while the read gap is still sensing data. The longitudinal extent of the servo areas indicates, respectively, beginning of tape (BOT) and end of tape (EOT). A leader portion includes a magnetic coating for facilitating calibrating magnetic recording apparatus to each particular article.

Abstract: A band-compressor devices designed to match to one another two systems having different pass bands, comprises means for coding input signals in the form of N digital signals corresponding, at any instant, to the amplitude of the input signal with respect to N quantizing levels. N bistable trigger stages of RS or JK type, followed by as many D-type bistable stages, are provided to receive said digital signals on the one hand and pulses furnished by a clock on the other. The output signals from the bistable stages of type D are then recombined in an adder in order to furnish analog signals or in a coder for furnishing signals in binary form.

Abstract: The tube LR is normally powered from the mains supply 2, 3 via a reactor RE, and in the event of mains failure the tube is supplied from a battery powered high frequency oscillator OSC coupled via a winding L3 of a transformer TR1 to a winding L5 connected between a starter GL and a filament G1 of the tube. A capacitor C5 has a high impedance at mains frequency and a lower impedance at the oscillator frequency, the oscillator producing voltage transients so that the tube LR will start even with cold filaments G1, G2. An electromechanical or electronic relay turns the oscillator OSC off if the mains supply is present. Alternatively, the battery charging current may saturate a transformer (TR2), (Fig. 2), in oscillator OSC and also establish a voltage drop to hold a transistor (T1) in the oscillator OSC blocked when the mains supply is present. The transformer TR1 has a further winding L4 having the same number of turns as winding L5 so that when the oscillator is operating points 4 and 5 are at the same potential, whereby if the switch S is closed there is no potential drop across the mains terminals 2, 3 so that the oscillator will not be loaded by any other load connected across 2, 3. The oscillator OSC includes a circuit (D2, C4, T2) to turn it off if excess voltage is produced, eg. if the tube LR is disconnected. <IMAGE>
