Title: Improvements in and relating to automatic gramophone apparatus
IPC: G11B3/12
Filed: 1947-10-04
Abstract: 636,971. Automatic gramophones. PREARIS, M. Oct. 4, 1947, No. 26754. [Class 40 (ii)] A gramophone pick-up arm which is normally supported in an inoperative. position above a record and moves to its operative position when an electromagnet is actuated by the operation of a switch, is automatically raised at the end of the record and returned to its initial position under gravity. A gramophone pick-up arm d, Fig. 3, is normally held with the needle f of the pick-up f out of engagement with a record g on a turntable b by a lever l urged to its upper position by a counterweight j. When it is desired to play the record, coin operation of a switch (not shown) momentarily energizes an electromagnet k to pull down lever l, Fig. 4, and lower the pick-up to the start of the record. Lever l is retained in its lower position by a spindle m which is normally below lever l, Fig. 3, but which is moved to the right by the extremity of lever l, during descent of the latter, to rotate a lever n about its pivot o, a counterweight q returning lever n with spindle m above lever l, Fig. 4, when the latter is in its lower position. The gramophone motor is also started when the switch is operated so that reproduction of the record commences. Towards the end of the recording, engagement of pick-up arm d and a stop r, Fig. 4, moves lever n to the right until, at the end of the recording, spindle m is out of engagement with lever l and the latter rises to lift the pick-up off the record, Fig. 5. The pick-up arm d then returns under gravity down the sloping portion of lever l until arrested by a stop s at its initial position where it remains unless the switch is again operated to repeat the cycle. An alternative arrangement in which the electromagnet is normally energized and the pick-up is lowered on to the record upon de-energization is referred to. A plurality of switches controlling a plurality of pick-ups is referred to. The Provisional Specification refers to : (a) means for returning the pick-up arm before completing the playing of a record ; (b) a switch operated by the pickup arm, when it returns to its initial position, to operate the electromagnet and replay the record automatically ; (c) rectification of the output of an amplifier associated with the pickup to bias a thyratron which, at the end of the record, initiates return of a push-button operated to select a record and stops the gramophone motor ; (d) pictures automatically rendered visible when the pick-up arm engages the record.

Abstract: 1510205 Quadraphonic systems; reducing crosstalk MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd and NIPPON VICTOR KK 25 June 1975 [25 June 1974 30 Jan 1975] 26916/75 Headings H4R and H4L In a transmission system for transmitting respective angle modulated signals over respective transmission paths, e.g. in the disc recording of quadraphonic signals, signals of a predetermined frequency band which are conducive to the generation of interference distortion between the transmission paths are filtered out from each path, and a proportion of the signal in each path is mixed with the signal in the other path, before recombination with the remaining signal in the path and application to the angle modulators to modulate respective carriers for each path. In one embodiment, Fig. 4, the mixing ratio can be varied in accordance with the difference between the signals in the two paths, while in an alternative embodiment, Fig. 6 (not shown), the frequency band of the signals applied to the mixing circuit is varied with the difference between the signals in the two paths. As shown in Fig. 4 amplifiers 31a, 31b are fed with signals Da and Db which are each difference signals between respective pairs of signals of a quadraphonic programme. High frequency portions of the difference signals are fed direct to respective adders 33a and 33b via filters 32a and 32b while the low frequency portions, e.g. below 500 Hz, selected by filters 34a and 34b are applied via level adjusting controls 35a and 35b and amplifiers 36a and 36b to the mixing circuit 50 which cross couples the signals in the two paths. The cross coupled signals after amplification, are applied to the adding circuits 33a and 33b to be combined with the high frequency portions of the signals to form signals which angle modulate respective carriers which are subsequently combined with respective sum signals of the respective pairs of quadraphonic channel signals to be recorded on a respective wall of a record groove. The mixing circuit may be controlled manually but preferably uses a photo-sensitive resistor 52 which is arranged to be illuminated by a light emitting diode or other source fed with a signal derived from the difference between the two mixed signals, derived by subtractor 53, so that the mixing ratio is varied to maintain the difference between the signals below a predetermined value. A complete circuit is described, Fig. 5 (not shown). In the alternative embodiment, Fig. 6 (not shown), the output of the subtractor circuit controls the cut off frequencies of the high and low-pass filters separating the signal to be mixed from the remainder of the signal.
