Abstract: 1,209,360. Reverberation devices; transducers. AKUSTISCHE u. KINO. GERATE G.m.b.H. 4 Dec., 1968 [7 Dec., 1967], No. 57483/68. Headings H4J and H4R. A reverberation system includes two helical spring delay members which are of different length and transit time properties with an input and output transducer associated with each spring. The frequency of the signal applied to the system is divided so that both springs are subjected only to torsional vibration. The frequency range is preferably equally divided and this may be accomplished mechanically and/or electrically. In the wholly mechanical system shown, spring 1 has a longer transit time, e.g. 120 ms., and spring 2 a shorter time, e.g. 60 ms., and the springs are connected at each end to rotary magnets 3, 4 of input and output transducers of the dynamic type. The magnets 3, 4 are connected to a fixed part of the system by wire elements 5 which are axially stiff but torsionally soft for the longer spring and wires 7 which are stiff axially and torsionally for the shorter spring. If electrical frequency division is used a low-pass filter is connected in the circuit of one or both of the transducers for the longer spring and a high pass filter in the circuit associated with the shorter spring, Fig. 2 (not shown). Preferably the high pass filter is replaced by a band pass filter and the transducer magnets are embedded in foam.

Abstract: 1373938 Digital computers; Searching vector stream TEXAS INSTRUMENTS Inc 23 Dec 1971 [4 Jan 1971] 60071/71 Heading G4A A circuit, e.g. in a digital electric computer system, is arranged to search a vector stream for an element having a predetermined characteristic, e.g. the largest or smallest element. A vector is defined as the ordered array of elements (X, X 2  ... Xv(X)). X i  is the ith component of vector x and the number of components v(x) is the dimension of x. A numerical vector X may be multiplied by a numerical quantity k to produce the scalar times vector multiply kxX (or kX) defined as vector z where Z i =kxX i . A matrix M may be formed from a two dimensional array of elements. Apparatus is described for carrying out a magnitude search for non-fixed point vectors (Fig. 1), for fixed point vectors (Fig. 2, not shown), or for both (Fig. 4, not shown) using a vector stream or trace (Fig. 3, not shown). The hardware shown in Fig. 1, is part of the computer arithmetic unit and the input and output thereof lead to the memory buffer unit. The first element of a vector stream is placed in register 21, the other elements are applied serially via register 33 to register 19 whence they are compared serially with the element in register 21. If the largest element is being sought, if the element in register 21 is greater than the element in register 19 then the element in register 19 is used for the next comparison. If not the two elements are interchanged and the other element is used for the comparison. The remaining circuitry indicates the address of the element in the vector trace.

Title: Feedback coders

Filed: 1969-12-10
Abstract: 1285937 Analogue/digital converters WESTERN ELECTRIC CO Inc 10 Dec 1969 [13 Dec 1968] 60270/69 Heading G4H  In an analogue/digital converter of the type in which the difference between a feedback reference signal and the unknown signal is integrated, during time intervals T1, the integrator input being fed to a trigger circuit 23 (Fig. 1) during time intervals T2 which when its input exceeds a threshold delivers an output pulse to channel 18, the value of the feedback signal depends on the pulse train from trigger 23. If a series of "1" or a series of "0", are transmitted the feedback increases or decreases towards its maximum or minimum value of + or -5 units respectively. Two or less consecutive similar bits result in a feedback signal of + or -1 unit. The value of the feedback signal is determined by the output of shift registers 30, 40 which are cleared at each change in the transmitted digital signal. Consecutive "1" signals pulse shift register 30, the output of the second third and fourth stages of which control voltage generators weighted 1, 1, 2 these signals being added to a unit voltage from source 36. Register 40 is similarly pulsed by consecutive "0" signals and controls negative voltage generators. The weighted signals are fed via a switch 14 the setting of which is determined by the transmitted signal to a comparator 12. At the receiver the transmitted bits similarly control shift registers 62, 63 (Fig. 2) the outputs of which control weighted voltage generators connected to summing circuits 64, 65. The setting of a switch 70 to which the received bits are fed selects the output of either summing circuit 64 or 65 for connection to a filter 60. In a modification (Figs. 4 and 5, not shown) the integrator -output is compared with the average value of the outputs of the summing circuits (135, 135) the difference signal being fed to the trigger to determine the bit value. This reduces errors resulting from overshoot in the integrator output.
