Title: Vector analysers for ascertaining the phase angle of a vector
IPC: G06G7/22
Filed: 1971-04-19
Abstract: 1336237 Electric analogue calculating SIEMENS AG 19 April 1971 [18 March 1970] 22774/71 Heading G4G A device for determining the magnitude and phase angle of a vector from two orthogonal components thereof comprises two quotient formers 1, 2 to one input 3, 4 of each is applied a signal proportional to respective ones of said components, squaring means 5, 6 for squaring the outputs of the quotient formers, comparison means 7 for forming the difference between the sum of the outputs of the squaring means 5, 6 and a constant quantity E, a device 8 which receives the output of comparison means 7 and whose output, which is shown to represent the magnitude of the vector, is connected to the other inputs of the quotient formers 1, 2 and phase angle forming means connected to the outputs of the quotient formers to determine the phase angle of the vector. Two arrangements for forming the phase angle are shown in Fig. 2. On the left of the dotted line I the outputs of quotient formers 1, 2 which outputs are proportional respectively to the cosine and sine of the phase angle, are fed to one input of respective multipliers 15, 14 whose outputs are subtracted one from the other at 16 and the difference so obtained is passed through a proportional-plusintegral device 17 and through a sine and cosine generator 18, 19 to respective other inputs of multipliers 14, 15. It is shown that the signal at terminal 20 will then represent the phase angle of the vector. On the right of line I a phase angle forming circuit is shown in which the output of quotient former 1 is added at 21 to a fixed signal E, which represents unity, the sum is halved and fed through a square root extractor 23 and then to an arc-cosine generator 29 either through a switch 25 or through an inverter 28 and switch 27. Switches 25 and 27 are closed in accordance with the polarity of the output of quotient former 1 to provide a unique value of half the phase angle which is multiplied by two to provide the phase angle at 31. In Fig. 4, (not shown), a phase angle forming circuit is shown in which unity is added to the output of quotient former 1 and the sum divides the output of quotient former 2, the resultant signal being fed into an arc-tangent generator then multiplied by two to give the phase angle.

A yarn cone or cheese winding machine comprises a yarn feeding cylinder, a core initially in driven contact therewith, any diameter of the core being not more than one third the diameter of the cylinder, a traverse cylinder having a reversely threaded screw cam slot in the surface thereof positioned below the yarn feeding cylinder for feeding yarn over the cylinder to the core, the traverse cylinder being mounted with its axis parallel to that of the yarn feeding cylinder, and a yarn guide actuated by the traverse cylinder to reciprocate longitudinally of the yarn feeding cylinder. The cones or cheeses 22, carried by arms 20, 21, are wound upon cores and driven by frictional contact with drums 11 provided with a number of end-traversing grooves 27. The drums 11 are formed with webs 87 bolted together at 88 and keyed at 89 to a shaft 12 driven by a motor 66 through a chain or belt 63. An oscillating traverse eye 26 is also provided and carried on a lever 13 pivoted at 42. The other end of the lever 13 comprises a ball 40 which engages in a socket 41 in a traversing bar 15 reciprocated by an adjustably-pivoted lever 48 oscillated by a cam 58 rotated by a shaft 59 driven by a chain or belt 60 from the motor 66. The belt 63 also rotates a shaft 80 upon which pawls 17 are mounted by eccentrics 79. On a shaft 78 is positioned a ratchet 16 to which the ends of a chain 30 are attached, the chain 30 passing over a sprocket 32 on the yoke 19 carrying the cone or cheese 22. If the yarn 23 from the supply cop 24 breaks, a lever 18 moves upwardly and the spring-biased pawls 17 move the ratchet 16 to lift the package 22 from the drum 11. At the same time a chain 33 attached to the ratchet 16 moves a lever 35 to lift the ball 40 from its socket 41 in the traverse bar 15 to stop the oscillation of the guide lever 13. A motor 116, which drives the drums 11 on one side of the machine, also drives conveyers 67 in troughs 71 by which packages and cores are delivered from and fed to the machine. The tubes or cones are resiliently gripped between spring-urged manually-retractable frusto-conical heads, carried by ball bearings, and frusto-conical counter-pressure members also carried by ball bearings (Figs. 11 and 12, not shown). The arms 21 may be rotated on a hub 90 provided with a number of openings 91 in which a pin 94 (not shown) may be adjustably entered to alter the " cone angle."

Abstract: 501,358. Conditioning air. CONSOLIDATED AIR CONDITIONING CORPORATION. Aug. 27, 1937, No. 23493. Convention date, Sept. 4, 1936. [Class 137] Air of predetermined CO2 and odour content is maintained in an enclosure 11 by admitting a quantity of fresh air through an inlet 14 into a circulating stream sufficient only to maintain the CO2 content low but not to remove odours, discharging a like amount from the circuit as from window crevices &c. 23, causing part of the stream after leaving the enclosure through a duct 20 to pass through beds of adsorbent material having a greater affinity for odorous gas than for atmospheric water vapour in a deodorizer 25 and rejoin the main stream in a relatively odour-free state so that the impure portion is sufficiently diluted to maintain the required low degree of odorous gas content, the air then being conditioned in a chamber C containing a heater 17, spray 18 and moisture eliminator 19, to provide the desired temperature and moisture content before return to the enclosure through a duct 13. Control of the byepassed stream may be effected in response to the moisture or heat gain in the air passing through the enclosure due to the varying number of occupants since these increments will correspond to that of the odorous gas content. A damper D<3> in the pipe leading to the deodorizer is actuated by humidistats P, Q, in correspondence with the relative humidity in a chamber 0 and duct 20 respectively, chamber O being supplied with air from the return duct 13 and brought by means of a coil 36 to the same temperature as the air in duct 20. Or the damper may be actuated by means of wet bulb thermostats in ducts 13 and 20 or duct 13 and the enclosure. Another thermostat in the enclosure may be associated with an electromagnetic switch and a hand switch for controlling the supply of current to a motor 31 driving a blower 28 returning the deodorized air to the main stream. The amount of air passed through the conditioning chamber may be controlled by means of dampers D<1>, Dll, in ducts 21, 22 beyond duct 20 and in a modification the inlet to and outlet from the deodorizer are located in a duct between the ducts 21, 22. An adsorber unit employing activated carbon as described in Specification 501,359, [Group VI], may be utilized.
