Title: Synchronization means for reception of pcm signals
IPC: H04L7/033
Filed: 1972-12-01
Abstract: 1418467 Automatic phase control CENTRE NATIONAL D'ETUDES SPATIALES 1 Dec 1972 [3 Dec 1971] 55536/72 Heading H3A An arrangement for synchronizing a local clock signal, generated by oscillator VCO, with a received digital data signal X(t + #) includes a phase comparator A which comprises: two channels El, L1, each having an integrator I E1 , I L1  which functions for overlapping periods, each equal to one clock period and a non-linear, e.g. square law, element NL E1 , NL L1 ; and a commutation arrangement C E1 , C L1  functioning at a submultiple of the local clock signal for extracting signals which are formed by the integrators in time intervals comprising an integral number of clock periods and stored for equal succeeding time intervals. The outputs from the commutator are fed to a differencing circuit S to provide the control signal for the VCO. In the embodiment of Fig. 2, the comparator includes a second pair of channels E2, L2 which operate in alternate time slots with the first two as illustrated by the waveforms of Fig. 4 (not shown). The data input is applied to the two pairs of channels by mixers M1, M2 which receive the clock signal as their second input. This clock signal is derived from the VCO by a divider circuit L detailed in Fig. 5 (not shown). A modification Figs. 13a, 13b (not shown) for data signals conveyed by a subcarrier having a frequency which is a submultiple of the clock, comprises two comparators (A, A<SP>1</SP>) one operating at a rate dependent on the clock rate, and the other at the sub carrier frequency. The two outputs are then summed to provide the control signal for the VCO.

Abstract: 1,244,750. Electromagnetic actuators. RUNTAL HOLDING CO. S.A. 28 Nov., 1968 [7 Dec., 1967], No. 56407/68. Heading H1P. The working stroke of an actuator is transmitted from the armature to an hydraulically damped member by means of a spring, the armature of the actuator moving against a return spring. As shown, Fig. 1, a fixed yoke 1 carrying a coil 7 attracts an armature 2 connected to a plate 4 via a sleeve which slides along a push rod 6. The armature is biased to its unenergized position by a return spring 3 and is connected to the push rod 6 by a spring 8. When the coil is energized (ac) the armature 2 moves upwards and compresses spring 8 which exerts a force on the push rod 6 the movement of which is retarded by an hydraulic damping cylinder 9. When the coil is de-energized the armature is driven downwards by the return spring 3 and simultaneously returns the push rod by engaging collar 5. The return movement is also retarded by the damping cylinder 9. The upper end of the housing may be provided with a stop for the push rod to limit its travel. This stop may be fixed or adjustable (41), Fig. 4 (not shown), or its position may be continuously varied, Fig. 5 (not shown), or may be selectively operated (42), Fig. 4 (not shown). The damping cylinder may contain a disc valve to provide a fast return movement, Fig. 2 (not shown), and the outlets may be constructed to provide a desired response characteristic.

Filed: 1978-07-25
Abstract: In a vortex type flowmeter, a vortex-shedding obstacle includes a block 14 fixedly mounted across the flow tube at right angles to the direction of flow, the block having a substantially square cross-section to present a flat face to the incoming fluid. The width of the block has its maximum value at the mid-point thereof and diminishes gradually toward either end where the width assumes its minimum value such that the upper and lower faces of the block are bellied and the front face has a double-convex contour. The maximum width value affords an efficient shedding action, the means width value of the block being significantly smaller than the maximum value to substantially reduce the pressure drop produced by the meter. <IMAGE>
