Title: Sound reproduction systems
IPC: H04S3/02
Filed: 1972-09-01
Abstract: 1396354 Quadraphonic systems CBS Inc 1 Sept 1972 [1 Sept 1971] 40741/72 Heading H4R In a matrixed quadraphonic system a gain switching logic circuit is fed with the output signals of the decoder matrix, and is responsive to the relative amplitudes and phases of the signals to derive two gain controlling signals which are applied to control the gains of the amplifiers feeding respectively the front and the rear speakers. As described, the coding and decoding matrix may be of the type described in Specification 1,387,874 providing four output signals L<SP>1</SP> # , R1 # , L<SP>1</SP>b, R<SP>1</SP> b , containing respectively predominant L # , R # , Lb, Rb, components with the L<SP>1</SP> # , R<SP>1</SP> #  signals each containing lower amplitude components Lb and Rb which have each suffered a phase shift differing relatively by 90 degrees, and the L<SP>1</SP>b and R<SP>1</SP>b signals each containing lower amplitude components L #  and R #  which have each suffered a phase shift differing relatively by 90 degrees. The four output signals are applied to terminals 30, 36, 32, 34, Fig. 3, and after filtering, to remove non-directional low frequency components, the amplitudes of the two front channel signals are compared in rectifier comparator circuits 82, 88, 91, and the amplitudes of the two rear channel signals are compared in amplitude in rectifier comparator circuits 84, 86, 93. In addition the phases of two front channel signals are compared one with the other in squaring circuits 120, 122 and comparator 128, similarly the phases of the rear channel signals are compared in 124, 126, 129. The outputs from the amplitude comparators are applied as gating signals on the outputs of the phase comparators so that only when the amplitudes of the two front signals, or two back signals, are equal is the respective gate 110 or 112, opened to allow the phase comparator output signal through. The phase comparators provide an output which is zero when the signals fed thereto are in phase, increasing to a maximum when the signals are 180 degrees out of phase. The phase comparator signals in respect of the front and rear channels are fed to comparators 138 and 140 so that when the front, or rear, channel signals predominate the respective front, or rear, channel amplifiers have their gains enhanced relative the gains of the amplifiers in the other channels.

Title: Improvements in or relating to line communication systems
IPC: H04B3/10
Filed: 1965-10-01
Abstract: 1,084,651. Pilot controlled A.V.C. systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 1, 1965 [Oct. 6, 1964], No. 41740/65. Heading H4R. In a communication system using a pilot-operated level control system, Fig. 1, the pilot signal received at the terminal station 8 is applied via a selective pilot repeater 15, and rectifier 16 to a comparator circuit 17 where the level of the received pilot is compared with a reference voltage applied at terminal 18. The error voltage from the comparator 17 is applied via amplifier 19 to control an impedance, e.g. a thermistor, in the feedback path of the final amplifier 10 and is also applied to a marginal supervision device 21 which produces a positive, a zero, or a negative control voltage dependent on whether the pilot level lies respectively above, between, or below the two marginal supervision limits. The control voltage from the supervision devece 21 is applied to a modulator 28 on the output of generator 29, so that either positive pulses, no signal, or negative pulses, are applied to the control line 22. The signals on line 22 are applied to a motor 35 which is coupled to the frequency determining element of an oscillator 34 whose output is fed to the line 2 to control the gain of the intermediate repeaters 4, 6, and 9, each of which includes an amplifier e.g. 36, 37, 38, a limiter, e.g. 39, 40, 41, a discriminator, e.g. 42, 43, 44, and a control impedance in the feedback path, e.g. thermistors, 11, 12, 13. Thus gross errors in the pilot level are detected by the supervision device 21 and lead, via the variable frequency oscillator 34, to an adjustment of the amplification of the repeaters 4, 6, and 9, preferably overcorrecting, as described in Specification 1.078,945. while small errors are corrected in the final amplifier 10. Should the pilot frequency fail a relay 45 operates to open contacts 46 in the supervisory device so that no control signals are sent over line 22 and thus motor 35 is left in its existing position so that the gain of the repeaters 4, 6 and 9, is left unchanged. In a system including a separate channel for each direction of transmission the control signals from the marginal supervisory device 21 may be transmitted over the other channel preferably, as described with respect to Fig. 2 (not shown), by amplitude modulation of the frequency-modulated signal transmitted for the control of the repeaters in the other channel.

Abstract: 919,123. Slide changing mechanisms. KAMERAUND KINOWERKE DRESDEN VEB. Dec. 6, 1960, No. 41957/60. Class 97 (1). In an automatic slide-change mechanism for slide projectors, comprising a reciprocable slide transport mechanism, a crank mechanism drivable by means of a motor through a gear mechanism and an elastic coupling device arranged between said crank mechanism and said transport mechanism for transmitting the movement of the crank mechanism to the transport mechanism, said elastic coupling includes two elements for connection, respectively, to the crank mechanism and the transport mechanism, which elements are provided with noses or dogs engageable with a driving member arranged between said elements under the action of a torsion spring carried by said elements. As shown (Fig. 1), a motor 1 is connected by way of gears 2 and 3, a crank 4, a link 5, a crank 6 and an elastic coupling 34, 39 to a lever 8 one end of which co-operates with slides (not shown) to push them into a projection gate 41 along a channel 13 and the other end of which is coupled through a link 9 to a lever 10 pivoted at 11 and having a pin 12 for returning said slides along said channel out of said projection gate. The elastic coupling (Figs. 2 and 3), comprises two sleeves 30, 32 which are freely mounted on a spindle 7, are provided with dogs 31, 33 respectively and are rigidly connected with the members 6 and 8, respectively, said spindle 7 having a pin 39 engaged at opposite ends by said dogs under torsion of a helical spring 34, one end of which engages in a hole 40 in the crank 6, the other end of which engages in a hole 38 in the lever 8 and the middle portion 37 of which is looped over an end 39 of said pin 40. Provision of this elastic coupling reduces jerks in the event of jamming of the changing device and also allows the crank 6 to continue operating in the event of such jamming. A lever 17, coupled to the lever 10 by means of a pin-and-slot coupling 15, 16 and pivoted at 18, enables manual adjustment of the slide transport mechanism to be effected (after jamming, for example) this manual adjustment being facilitated by a part 20 which is releasably held in the position shown and may be pivoted out of the way (Fig. 4, not shown) when not required.

Abstract: 1305154 Feeding sheets SIEMENS AG 10 Sept 1971 [23 Sept 1970] 42296/71 Heading B8R [Also in Division F2] Sheets or cards are fed either continuously by a roller 23 on a drive shaft 1 or stepwise by rollers 21, 22 on a shaft 6, according to the setting of pressure rollers engageable with the rollers 23, 21, 22 and according to whether the rollers 21, 22 are indexed stepwise or are stationary, which is determined byasolenoid 15. The shaft 6 is indexed by a ratchet wheel 8 mounted thereon. The ratchet wheel is indexed by a ratchet 9 fixed to a shaft 10 freely mounted in a transfer socket 5 freely mounted on the shaft 6. Also fixed to the shaft 10 is a control rocker 11 which carries a cam roller 13. The rocker 5 is oscillated by a cam 2 on the shaft 1 engaging a cam roller 4 on the rocker, and by a compression spring 7, thus oscillating the ratchet 9 bodily about the axis of the shaft 6. During stepwise feed operation, with the solenoid 15 energized, a cam 3 on the shaft 1 and a compression spring 14 act on the rocker 11 to move the ratchet into engagement with the teeth of the ratchet wheel during its travel in one direction and out of engagement on its return movement. When the solenoid is de-energized, a spring 17 moves the nose 18 of a pawl 16 into engagement with a recess 19 in the rocker 11 to hold the roller 13 out of engagement with the cam 3 and the ratchet 9 out of engagement with the ratchet wheel. A detent roller 20 engaging a tooth of the ratchet wheel, or other braking means, prevents movement of the wheel when not being indexed by the ratchet 9. The nose 18 and recess 19 are in alignment with the axis of the shaft 6.
