Title: Differential pulse code modulation transmission system

Filed: 1970-12-29
Abstract: 1339019 Differential PCM systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Dec 1970 [31 Dec 1969] 61543/70 Heading G4H A comparator 61 supplies the difference between an input signal 60 and an integrated quantized signal 62 to a quantizing circuit where it is compared with a set of reference levels 83- 90 which are each cyclically varied between respective maximum and minimum values. The arrangement provides better quality transmission for a given number of transmitted code bits by effectively reducing the mean deviation of the quantized signal. For television signal transmission, the reference levels may be cyclically varied at a sub-multiple of the line or frame frequency, the eye automatically averaging between brightness levels produced in successive lines or frames. The reference levels 83-90 may be supplied from a voltage divider which is connected to a D.C. source in combination with an A.C. source providing the desired variation, e.g. alternately maximum and minimum levels or with one or more additional intermediate levels. The 2-state outputs of differential amplifiers 75-82 are fed to a pulse coder for transmission and to respective resistors 115-122 in a summing circuit. Resistors 115-118 corresponding to positive quantizing levels may be equal in value to corresponding resistors 122-119 for negativelevels and are dimensioned so that in sum they correspond to the different representational weights. For example, the mean quantizing levels may be 0, 5, 13, 29, differences quantized between adjacent ones of these levels may be assigned weights of 2, 8, 18, 40, respectively, and resistors 118-115 may be weighted to produce currents in the ratio 2, 6, 10, 22. The reference levels 83-90 may be varied by Œ17À25% and it is preferred that when there are intermediate levels between the maximum and minimum the positive and negative reference levels corresponding to a given representational weight are varied in such a way that the reference levels in each intermediate pair have different absolute values at any given time.

Patent GB-699389-A (GB)
Abstract: 699,389. Automatic speed control systems. AKT.-GES. BROWN, BOVERI, & CIE. Oct. 25, 1951 [Oct. 25, 1950], No. 24943/51. Class 38 (iv). In an automatic speed control system for a separately excited D.C. motor the armature or field of which is supplied from a grid-controlled rectifier, the motor drives an A.C. tachometer generator, the output of which is compared in phase with the A.C. mains used to supply the rectifier, and the resultant voltage controls the rectifier. The armature 4a is supplied from the rectifier 3a and drives a three-phase tachometer generator 6a through a variable speed drive 5a so that the speed of the motor can be varied. The rotor windings of the generator are energized from a D.C. source 19 via choke 12 and resistors 15. Each phase of the stator winding is connected in series with one phase of an auxiliary 3-phase network 20 supplied by the transformers 17 and 18. It is assumed that the tachometer output voltage is between 90 and 270 degrees out-of-phase with the reference network 20. Then it is shown that the resultant voltage (applied to the grid of the rectifier via switch 14) advances in phase as the tachometer voltage falls back and hence increases the rectifier output to restore the speed of the motor. Should the phase angle between the tachometer voltage and the reference exceed the given limits, the motor drops out of step. Hence at starting, a fixed frequency signal from transformer 16 is substituted for the tachometer voltage, the switch 14 being changed back to the position shown when the motor is " synchronized." The motor armature current flows in a winding on the choke 12 so that current changes induce a transient change in the excitation of the tachometer rotor in such a sense as to reduce hunting. Several similar motors are individually controlled, the reference network 20 being common to all motors. It is also stated that field control can be substituted for armature control, that a tension control (for a strip passing between rollers driven by the motors), can be superposed, and that the control voltage can be used to produce control impulses with a steep wavefront which in turn control the rectifier.

Abstract: In a system for separating one component from a fluid mixture, e.g. to produce a breathable fluid, by alternately presenting the fluid mixture to first and second beds 14, (16) (Fig. 1C not shown) respectively of adsorbent material, control valves 40 (or 46) admit the fluid under pressure from a supply conduit 24 to one selected of the beds for adsorption whilst control valves (42) or 48 allow purging of the other bed to a source of reduced pressure. A control device (52) (Fig. 1A not shown) generates first and second control signals which close valves 40 and (42) and valves (46) and 48, respectively. The first and second control signals partially overlap for a time period during which pressure is equalized between the first and second beds through an equalization valve 270. A pressure detector (50) generates a switching signal each time that the pressure in the supply conduit 24 becomes greater than a predetermined level. In response to the successive switching signals, the first and second control signals are alternatively initiated. <IMAGE>
