Title: Identification of the speed at which a tape was recorded
IPC: G11B15/087
Filed: 1976-12-08
Abstract: 1533648 Identifying recording speed of a prerecorded tape AMPEX CORP 8 Dec 1976 [19 March 1976] 51320/76 Heading G5R To identify the speed at which a pre-recorded tape 12 was recorded, the tape 12 is driven at any playback speed in a recorder/reproducer to replay a control track 16 on the tape, the ratio of the frequency of a capstan tacho 20 signal to that of a component of the replayed control track signal is measured, and a ratio-dependent logic level is developed indicative of the recording speed. 15 and 7 i.p.s. quadruplex video tapes each carry a control track 16 which when played at the correct speed has a 240 Hz signal. The capstan tacho 20 gives 3À84 KHz and 1À92 KHz at 15 and 7¢ i.p.s. respectively. The control track signal passes to a multiple capacitor filter 22 of a commutating filter 24 which acts like a synchronous detector working simultaneously at T/16 and T/8, where T is the capstan tacho frequency. The output of filter 24 passes to divide-by-eight 30, the output of which causes monostables 32, 34 to supply clock pulses to D- type flip-flop 38 and reset pulses to a divider 28 counting the tacho pulses. If a 7¢ i.p.s. tape is replayed at 7¢ or 15 i.p.s., filter 24 gives 240 Hz or 480 Hz respectively and divider 28 is reset every 1/30 or 1/60 sec. respectively, divider 28 repeatedly counting up to 64 in either case, i.e. below a threshold of 96 so that flip-flop 38 gives a low logic output indicating 7¢ i.p.s. Standard recording speed. Similarly for a 15 i.p.s. tape replayed at 7¢ i.p.s. or 15 i.p.s., filter 24 output is 120 Hz or 240 Hz respectively, and divider 28 repeatedly counts to 128 so that flipflop 38 gives a high logic output indicating 15 i.p.s. standard recording speed.

Abstract: 1326756 S.C.R. inverters PICKER-ANDREX X-RAY A/S 29 Oct 1970 [7 Nov 1969] 51432/70 Heading H3T [Also in Division H2] A circuit for supplying an X-ray tube 1 with D.C. pulses comprises a controlled rectifier 4 gated by a timing circuit 5, a commutation capacitor 6 charged via a current transformer 8 and a diode 7, and a controlled rectifier 9 gated by a timing circuit 10 to enable the voltage across the capacitor to be applied across and thereby switch off the rectifier 4. On closing a switch 13, the circuit 5 is supplied with power and after a pre-set time switches on the rectifier 4. Load current therefore flows through a transformer 2 and capacitor 6 is charged to provide a supply voltage to the circuit 10. After a predetermined time, a unijunction transistor in the circuit 10 is fired and supplies a gating pulse to the rectifier 9 which therefore enables the voltage across the capacitor 6 to switch off the rectifier 4. In the event of a short circuit in the load, the increase in voltage across the capacitor 6 causes a Zener diode in the circuit 10 10 become conductive and fire the unijunction transistor thereby switching on the rectifier 9 and enabling the capacitor 6 to switch off the rectifier 4.
