Title: Data recording systems and bi-phase mark encoder therefor
IPC: G11B20/14
Filed: 1972-05-05
Abstract: 1347199 Recording digital data EDMAC ASSOCIATES Inc 5 May 1972 [5 May 1971 2 Aug 1971] 21030/72 Heading G4H In a data recording system in which analogue data is converted into binary and then into biphase mark encoded signals which are recorded on magnetic tape, disc or drum, an amplitude detector 42 starts the recorder transport mechanism 66 and alters the clock rate for the A/D converter when the binary signal exceeds a given threshold, e.g. 10% of maximum. In Fig. 1, the outputs of four strain gauge circuits 11, 12, 13, 14 monitoring a motor or a human heart, are amplified, sampled in turn and converted at 18 to 8 bit parallel binary code. Searching is at a fast clock rate until one of the signals exceeds the threshold upon which timer 32 reduces the clock rate to 1/25 the search rate, resets the address counter 30 and frame interval counter 31 and starts the record transport mechanism 66. The frame interval counter controls a selector 38 to accept a frame word from matrix 36 instead of the output from converter 18 at the beginning of each recording period and periodically throughout the recording, for synchronizing during playback. The 8 bit parallel binary signals are converted at 50 to serial form and delayed in a shift register 52 to all the recorder to reach its proper speed to avoid loss of information on start up. The signals are recorded as bi-phase mark encoded signals. The search mode is resumed when no signal has exceeded the threshold in the last 5 seconds. Bi-phase mark decoder.-A decoder for the recorded signals is described with reference to Figs. 2 and 3, not shown. A frequency of 12 times the bit rate is generated by a phaselocked oscillator (III), a divide-by-8 counter is started by each boundary pulse as it arrives and a window pulse is generated from count 4 to count 8, during which the presence or absence of a mark pulse causes a flip-flop to deliver a "1" or "0".

Title: Improvements in or relating to loaded long distance cables
IPC: H01F1/00
Filed: 1930-07-16
Abstract: 354,523. L o a d i n g . S I E M E N S & HALSKE AKT.-GES., Siemensstadt, Berlin. July 16, 1930, No. 21558. Convention date, July 18, 1929. Drawings to Specification. [Class 40 (iv).] The loading of a cable is determined so that the product of hysteresis factor and current strength, which is a measure of the strength of disturbing harmonics, lies below a maximum predetermined for a given quality of transmission. The disturbing harmonics arise from variations of self-induction with signal strength (Flatter effect) and from simultaneous use of the cable for telegraphy and telephony. Hysteresis factor is defined as the factor which when multiplied by the product of current strength and frequency gives the loss due to hysteresis. Loading having a small hysteresis factor is used at the ends of the cable where current strength is greatest. The Specification contains a mathematical investigation of the problem and shows how to ascertain the value of the product of hysteresis factor and current strength corresponding to a given " clash factor " for the cable, the clash factor being the ratio of disturbing harmonics to signal current. The sum of the products for the various sections of the cable is then ascertained and the hysteresis factor of the loading where current strength is greatest, is adjusted to bring the sum within the predetermined amount. It is shown that the hysteresis factor is proportional to #h/u0 #L<3>/V where h is the hysteresis number of the magnetic material, u0 initial permeability, L induction, and V the iron volume. The hysteresis factor may therefore be reduced by using material with small h/#u0 by increasing the iron volume, or by a reduction of L. When the last-mentioned method is applied to a Pupin cable the length of coil field is reduced to keep L/C constant so that the reduction of the factor is proportional to #L. Specification 201,931, [Class 40 (iv), Telephones &c.], is referred to.
