Title: Adaptive signal encoders
IPC: H04B14/06
Filed: 1972-08-24
Abstract: 1363017 Adaptive analogue encoder WESTERN ELECTRIC CO Inc 24 Aug 1972 [30 Aug 1971] 39381/72 Heading G4H In a feedback type encoder for adaptively encoding samples of an analogue signal, the errors that would result from alternative outputs are calculated either one or two outputs ahead and the output yielding the least error is transmitted. The output is either 1 or 0 representing the presence or absence respectively of a directional change in the analogue signal between samples. The feedback step signal is charged by P for 0 output and - Q for 1 output and the feedback circuit also includes double integration facilities with multiplication factors F and L. As described, the (I-1) output has just been transmitted and the (I+1) sample is at the input. The analogue input is sampled at 115, the direct input IN (I+1) is fed to combine circuits 119 and 120 and the input delayed at 116 by one sample period [IN (I)] is fed to combine circuits 117 and 118. The combine circuits 117-120 calculate the errors assuming different output values. Circuits 117 and 118 calculate the errors in the coding of the Ith sample for a 0 and I output OUT (1) respectively. Circuits 119 and 120 calculate the errors in the coding of the I+1th sample for 0, 1 and 1, 0 combinations respectively of OUT (I) and OUT (1+1); the outputs corresponding to inputs IN (I) and IN (I+1). The outputs of circuits 117 and 119 (which both consider OUT (I)=0) are weighted and averaged at 121 and the averaged signal is rectified and fed to subtracter 123. Similarly, the outputs of circuits 118 and 120 (which both consider OUT (I)=1) are weighted and averaged at 122, rectified and fed to the subtracter. The output of the subtracter (which is positive when a 0 for OUT (I) gives the lesser error) is clamped to a positive or negative voltage at 164 and the corresponding pulse is transmitted on line 124 as OUT (I). The output pulse also operates switch 126 to terminal 127 for a 0 output or 128 for a 1 output. This applies the previous step voltage multiplied by either P or - Q to the input of one sampling period delay 131. This previous voltage STEP (I-1) is integrated in two stages; 111 with multiplication factor F and 112 with multiplication factor L and produces a synthesized replica of the input at 136. The signals from various parts of the circuits are multiplied by various factors according to equations derived in the specification, and fed to the combine circuits. To obtain the output in the more usual form, a combination of exclusive NOR gate 166 and one sampling period delay 167 may be used.

Abstract: 1366322 Arc welding systems; inverters MESSER GRIESHEIM GmbH 24 Aug 1971 [18 Sept 1970] 39730/71 Headings H2H and H2F An arc welding system includes an inverter for supplying a rectangular waveform alternating welding current between a welding electrode 5 and a workpiece 6. The inverter comprises a bridge formed by transistors 1-1 each of which has its base connected to a two stage transistor amplifier 40 and a flip-flop 11. Each flip-flop 11 is provided with a square wave input 18 supplied from a transformer 12, a diac 14, a bridge rectifier 16 and a mains transformer 39. A potentiometer 13 enables adjustment of the pulse width of the input 18 and transformers 22-24 supply the inputs 18 to the other flip-flops. Each flipflop 11 is also supplied with a square wave input 19 from a transformer 26 a diac 28 and a diode 30, the inputs 19 to the other flip-flops being supplied by transformers 36-38. Secondary windings 32-35 provide D.C. supplies for each amplifier 40. Outputs 20 of two of the flip-flops switch on the transistors 1, 4 to connect a D.C. source 8 across the electrode 5 and a workpiece 6 whilst during the next half cycle of the A.C. supply to the transformer 39, the transistors 1, 4 are switched off and the complementary outputs 21 of the other two flip-flops switch on the transistors 2, 3 to connect the D.C. source across the electrode and the workpiece but with a reversal of polarity. An alternating square wave voltage is therefore produced across the electrode and the workpiece and the ratio of the width of successive half-cycles may be adjusted. The transistors 1-4 may be replaced by thyristors and the control signals may be provided by an oscillator instead of the transformer 39.

In an integral reactor similar in many respects to that disclosed in the parent Specification employing light water for both the primary and secondary coolants, the primary coolant flowing through tubes 12 containing fuel elements and being pressurized to prevent bulk boiling and the secondary coolant flowing around the tubes to generate steam removed at 19, the primary coolant is pressurized by a gaseous phase medium, e.g. a vapour but preferably nitrogen, helium or hydrogen gas supplied to a number of cylindrical vessels 52 disposed annularly around the inner wall of the pressure vessel 17. The vessels 52 are connected to a common header 51 in the primary coolant circuit by tubes 54 extending downwardly from the header to the lower ends of the vessels whereby the primary coolant liquid presents a free surface in each vessel. The pressurized gas is supplied to the top end of each vessel 52 from a header 57. In a modification. Fig. 3, each vessel 52 encloses a cylinder 59 open at its lower end, the primary coolant from the header 51 being admitted through a pipe 62 to the space between the vessel and the cylinder. The primary coolant acts on the lower surface of a piston 60, the upper surface of the piston being acted on by the pressurized gas admitted through a pipe 63 from the header 57.

In apparatus for coating a web, e.g. applying a coating of dispersion in the manufacture of magnetic tape, an extrusion hopper 8 is provided (shown in detail in Fig. 2),which has an elongate chamber 17 into which the coating liquid is pumped via a port 19 and from which it passes via an elongate slot 18 to be extruded as a coating on a web 9 passing about a backing roller 10. In order to prevent sedimentation in the chamber 17 a cylindrical rotor 21, preferably having an effective density equal to the density of the dispersion, is rotated to give conditions of high shear rate -in the liquid in the chamber (defined as 200 cm/sec/cm). The hopper is cooled by fluid flowing through tubes 20<SP>1</SP> and passageways 20. The coating liquid is initially stored in a tank 2 having a stirrer 3 and is continuously circulated through a pump 4, filter 5 and tube 6 at a rate which gives high shear rate conditions in the circuit. Some of the liquid is led off through a pipe 7 and is pumped by a metering pump 12 to the hopper 8. The rate of pumping of pump 12 and the speed of rotation of the backing roll 10 are so regulated that the coating on web 9 is thinner than the width of the extrusion slot 32. In order to keep the coating in contact with the lower lip of the slot 32 during extrusion a low pressure manifold 11 is provided to enclose the adjacent region.

Abstract: 416,602. Colour photography. NORDMANN, C., Observatoire de Paris, Avenue de l'Observatoire, Paris. May 24, 1933, No. 15021. Convention date, June 28,1932. [Class 98 (ii).] In taking colour-record photographs on linear lenticular films, the use of an objective of as wide an angle as is desired is made possible by including in the optical system, between the objective and the film, means which reduces the aperture of the beam proceeding towards the film in an axial plane at right angles to the lenticular lines to the maximum value which will yield elementary lenticular images without overlap, but which leaves the aperture unrestricted in an axial plane parallel to the lenticular lines. The means may comprise a divergent cylindrical lens D, Fig. 3, reducing the effective aperture in the first-mentioned plane from w to alpha, in which case it will be necessary to use a similar optical system for the projection of the images. The result may also be achieved by employing between the objective and the film a colour-selecting filter F of rectangular form, Fig. 4, the width d, d<1> being chosen to reduce the aperture to the aforesaid maximum value which will avoid overlap, and the length d<1> 1, d 11 being chosen to use the full aperture of the objective employed.
