Title: Improvements in or relating to sweep frequency signal generators
IPC: G01R13/32
Filed: 1965-09-29
Abstract: 1,047,857. Automatic frequency control. SIEMENS & HALSKE A.G. Sept. 29, 1965 [Sept. 30, 1964], No. 41289/65. Heading H3A. In a sweep frequency generator in which the output frequency is automatically controlled by a periodic waveform produced by an a.f.c. generator the swept frequency range is stabilized by producing control pulses which determine at least one turning point in the periodic waveform. An output is taken from the sweep frequency generator and is fed to a discriminator to produce an output signal whose amplitude varies with the frequency of the sweep generator output. This signal is then fed to a comparator which produces an output pulse whenever the amplitude of this signal is the same as either of two adjustable reference signals. The output pulses thus produced are fed to switch the states of a bistable circuit to produce a square-wave output which is fed to a Miller integrator to produce a sawtooth sweep control signal for the sweep generator.

Abstract: 1,105,064. Melt-spinning apparatus. FIBER INDUSTRIES Inc. 29 Sept., 1965 [5 Oct., 1964]; No. 41321/65. Heading B5B. A melt spinning assembly has outer and inner rings 11 and 9 respectively with a top cover 8, which together form the body of the melt spinning pack which contains an annulus pierced by spinning orifices 10. A granular filtering medium 12 is retained in place by wire gauze annuli. Channels 20 are provided between an annular bridge plate 13 and projecting into the inner wire gauze 14, while the cylindrical walls of the outer gauze 15 are corrugated to provide inlet channels for the molten polymer. The melt enters the spinning assembly at inlet 17 and enters channel 21 through pipe. 16. After channel 21 is filled with the melt, the corrugations in gauze 15 fill and the molten polymer then percolates through the filter, in the direction of the horizontal arrows, and then flows down the channels formed by bridge plate 13 and inner gauze 14 to orifices 10. The assembly is mainly heated from an outer source, not shown, but additionally, an inner heating unit 19 is provided to ensure a more uniform distribution of heat. As shown, an inner void space 18 may be provided which makes the inner ring of extruded threads accessible through the centre of the assembly. The apparatus of the invention is particularly suitable for melt spinning polymers which are highly viscous, e.g. polyethylene terephthalate, nylon or polyolefins. The granular filtering medium is preferably silica sand, but may be any conventional material, e.g. steel balls, iron filings, stainless steel filings or glass beads.

Filed: 1974-09-24
Abstract: 1477185 Automatic phase control SIEMENS AG 24 Sept 1974 [20 Nov 1973] 41423/74 Heading H3A In a data transmission system in which a received data signal A and a local clock signal T, derived by frequency division of a generated signal D in a divider FT, are synchronised by delaying or advancing pulses of the signal D in a synchroniser SYN, the synchroniser, Fig. 2, comprises: a first store SP1 which produces a first signal in the presence of lagging distorting between the signals A, D; a second store SP2 which produces a second signal in the presence of leading distortion; a counter Z which counts from an initial value in a direction determined by the state of the signal T when the first signal is present; a third store SP3 which is responsive to a signal produced by the counter Z when it passes through zero during a count to produce a third signal; and a logic circuit LOG responsive to the first, second and third signals to produce a signal which delays or advances the pulses of the signal D to produce the signal at d which is fed to the divider FT of Fig. 1. Before being applied to the circuit SYN the signal A is differentiated and rectified to produce a train of pulses C. The logic circuit LOG comprises AND gate G1, inverter G2, two three input gating circuits ES1, ES2 which perform the logic operation z = x.y + w.y and a bi-stable K1 which is triggered by an input q to the "1" state if input p = 0 and input s = 1 and is triggered to the "0" state if input p= 1 and input s = 0. The resulting output from circuit LOG is "0" with the output from SP2 = 0 or with outputs SP1 = 1, SP2 = 1, SP3 = 1 and changes to "1" at the next trigger pulse at q if SP2=1, SP3=0. It then remains at "1" if SP1 = 0, changing back to "0" if SP1 = 1, SP2 = 0 or if SP1 = 1, SP2 = 1, SP3 = 1. The circuit synchronises with a transition in T midway along a pulse in signal D, this position being determined by the count in the counter Z. The pulse train D is fed to a divide-by-two stage K2 whose output is fed via OR gate G8 to output d which feeds pulses to the input of divider FT of Fig. 1. Depending on the phase adjustment required, pulses in the train at d are inhibited by resetting K2 with an input at r, or further pulses are added at the other input of OR gate G8.

Title: Sound reproducing systems

Filed: 1971-09-06
Abstract: 1360411 Quadraphonic systems COLUMBIA BROADCASTING SYSTEM Inc 6 Sept 1971 [19 Oct 1970] 41512/71 Heading H4R In a matrixed four transducer two channel stereophonic system employing a logic circuit to differentially vary the gain of amplifiers feeding the front and back loud-speakers, the logic circuit employs cross correlation between the two signals containing predominantly front information and between the two signals containing predominantly back information, in order to detect the presence of front or back signals only, and adjust the gains of the amplifiers accordingly. As described the two channel signals, of the form described in Specifications 1,347,993 and 1,347,994, respectively contain L and R front signals together with proportions of both L and R back signals, in quadrature and with different signals leading in the two channels, as shown adjacent lines 28 and 30 in Fig. 2A. The two channels are relatively phase displaced, in phase shifting networks 40 and 42 such that, on combining in networks 48 and 50 signals are formed, on lines 58 and 60 in which a respective one of the back signals is reinforced while the other back signal is cancelled. The phase shifted signals on lines 56 and 52 and the combined signals on lines 58 and 60 are fed via respective gain controlled amplifiers 64, 66, 68 and 70 to the reproducers at the corners of the listening area. Control signals for the gains of amplifiers 64, 66, 68 and 70 are derived by passing the phase shifted signals on lines 56 and 62 through high pass filters 92 and 94, to remove the low frequencies, which contain little directional information. The signals are combined in networks 104 and 108, similar to networks 48 and 50, to provide signals containing respectively predominantly L B  and R B  information. These signals are correlated in multiplier 150 and integrator 160, 162, to provide a "back signal present" output, while a similar multiplier 144 and integrator 154, 156, handling the signals from the high pass networks 92, 94, in which the front signals predominate, gives a "front signal present" output. The two signals from the integrators are shaped and compared to provide control signals for the gains of the reproducer amplifiers 64, 66, 68, 70. To improve the operation of the correlators, amplifiers 96 and 98 on the inputs to the control circuit are provided with automatic gain control by detection and averaging of the four signals feeding the multipliers.
