Abstract: 1,236,274. Automatic exchange systems. P. LUCAS, J. DUQUESNE, and C. ABRAHAM. 28 Oct., 1968 [27 Oct., 1967], No. 50976/68. Heading H4K. In a cyclic scanning arrangement binary signals characteristic of the states of a group of circuits (e.g. 128 lines) are simultaneously stored in a register and read out in sub-groups (e.g. eight sub-groups of sixteen bits) for analysis by a central processor. The arrangement may be used in conjunction with a space division network or a time division network, in which case signals from a group of adjacent time slots must be converted to parallel form for entry into the register. Systems using each type of network are described. In each embodiment a 128 bit word designating the states of 128 corresponding lines is transferred to a register (e.g. by reading out a whole row of a scanning matrix), the bits are read out 16 at a time (by simultaneous pulsing of 16 output gates), entered into a further register, compared with 16 bits of a corresponding word read out from a fast store and specifying the states of the same lines as derived from a previous scan and if a significant change is detected, storing the new states and entering those states in a central processor for analysis. The words read out from the fast store have additional bits which instruct the comparator as to which changes of state are to be regarded as significant. An embodiment in which the central processor, the fast memory, the comparator and the 16 bit sampling arrangement are duplicated is also described. The additional bits read out of each fast store instruct the associated comparator to ignore differences which are being dealt with by the other comparator and processor.

Abstract: 1287319 Power-actuated pipe coupling FMC CORP 30 Oct 1970 [13 April 1970] 51624/70 Heading F2G Each of a number of clamp assemblies 10, mounted round a flanged pipe 20, comprises a motor 14 for rotating an internally-threaded hollow shaft 56, a non-rotatable shaft 60 threadedly-engaging shaft 56 and connected to a toggle-linkage 62, and a pair of clamping hooks 28 connected to the toggle-linkage such that longitudinal movement of shaft 60 in one direction (away from pipe 20) causes hooks 28 to move from the clamping position shown in two steps, the first being generally parallel to the pipe axes in the direction of arrow A and the second being generally curved and away from the pipe axes. As shown, a unit including motor 14 and shaft 56 is pivoted at 48 to brackets 40, 42, secured to pipe 20. The toggle linkage (links 64, 70, 76) includes fixed pivots 68, 80, a pivot 74 to which the end of shaft 60 is connected and a pivot 32 to which the hooks 28 are connected. Pins 110 mounted on the hooks are located in slots 106a formed in links 106 pivoted at 68. Movement of shaft- 60 away from the pipe 20 moves pivot 32, and hence the hooks, to the left until pins 110 bottom in slots 106a. Further movement of shaft 60 pivots the hooks away from the pipe against the action of springs 102. Movement of shaft 60 towards the pipe causes pivoting of the hooks towards the pipe until the hooks abut flange 24 and then generally linear shifting of the hooks until pad 36, carried thereby, engages flange 24. Pad 36 is formed with variously inclined faces 36a, 36b and 36c to allow flanges 24 of various diameters and thicknesses to be clamped. In a first modification, Fig. 5 (not shown), spring 102 is replaced by a spring acting between the hooks and pivot 68. In a second modification, Fig. 6 (not shown), fixed pivot 80 and link 76 are replaced by a block secured to pivot 32 and constrained to move parallel to the pipe axis.

Abstract: 1484910 Data transmission SIEMENS AG 6 Dec 1974 [14 Dec 1973] 52768/74 Heading H4P In order to shape the transmitted signals in a PCM data transmission system such that signal to noise ratio is optimized transversal filters are provided at both the transmitter and receiver, which together provide attenuation/frequency and phase/frequency characteristics such that at the receiver a partial response signal of class IV is produced (i.e. amplitude frequency response is given by /H(jw)/ = 2/sin wT/; phase frequency response by arg(H(jw)) = #/2sign[sin wT], where T represents the pulse duration of the PCM pulses for frequencies below an upper cut off, while above this cut off the filters block the signals. The required attenuation/frequency characteristic is produced conjointly, e.g. equally between the filters, whereas the required phase/frequency characteristic is produced by only one of them.  The filters at transmitter and receiver may respectively be as shown at SF, EF, Fig. 1. The filters incorporate delay elements V, weighting elements B and adders S to combine the delayed and weighted versions of the signal applied to each filter in accordance with the required response. The phase response is effected only in the transmitting filter SF, by means of the arrangement and sign of the weighting units. Simple low pass filters TP1 and TP2 ensure that high frequency signals outside the required band are not transmitted. In one particular embodiment, a tapped delay line with closed circuit termination is used as the transmitting filter (Fig. 2, not shown). This enables the weighting units to be doubly effective and provide an improved approximation to the required characteristic. At the receiver a tapped delay line with a buffer termination feeding a further weighting unit is used (Fig. 3, not shown), the buffer being highly ohmic to provide an in phase reflection which enables the weighting units connected to the taps to be doubly effective, and provides a pure attenuation response.

Abstract: 1282617 Acoustic fluid-flowmeter WESTINGHOUSE ELECTRIC CORP 3 Nov 1969 [26 Nov 1968] 53795/69 Heading H4D [Also in Division G4] A fluid velocity value V substantially independent of variations in the speed of sound C in the fluid is provided by a flow-meter in which circuits provide and combine signals indicative of the difference #T in travel time of acoustic energy through the fluid to two opposed transducer stations over a path of length L, of the time Tnom=L/Cnom where Cnom is a fixed assumed correct value of C, and of the difference ## between Tnom and the travel time of the acoustic energy to one of the transducer stations. V is computed from the relation V=C<SP>2</SP>#T/2L, where the actual sound velocity C differs from Cnom by an error quantity #C. In the Fig. 1 system, transmitter 10 causes downstream and upstream transducers 16, 17 to emit periodically towards each other and the resulting received signals pass through threshold circuits 23, 24 to the Fig. 2 digital timing and processing system. The downstream and upstream received signals respectively open and close gate 43 to feed clock pulses from oscillator 36 to counter 34 to give a count indicative of #T. An output signal at a time indicative of Tnom is provided by generator 48 when a preset count is reached by a counter fed with clock pulses from oscillator 50, and this output signal is time compared in #C generator 56 with either the received upstream signal or downstream signal, these received signals being gated alternately to generator 56 in respective successive measurement cycles of the system. A counter in generator 56 provides a count indicative of ## which is approximately proportional to #C. If Tnom occurs before the received downstream or upstream signal (i.e. Cnom>C) adder 72 is enabled and combines a -2#C signal with a digital signal representing Cnom from generator 60 to give Cnom-2#C. Similarly, if Cnom <C, adder 68 is enabled and gives Cnom + 2#C. Multiplier 87 provides an output approximating C<SP>2</SP> by multiplying the output of adder 68 or 72 by Cnom. A value V proportional to C<SP>2</SP>#T is then derived by multiplier 89 and averaged at 91 over several measurement cycles for application to output means 93. Details of #C generator 56 are given (Fig. 3, not shown).
