Title: Colour tube static convergence structure
IPC: H01J29/70
Filed: 1976-03-29
Abstract: 1507122 Electron beam deflecting apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 March 1976 [1 April 1975] 12472/76 Heading H1D A method of producing a magnetic convergence structure for the static convergence of coplanar electron beams in a colour display tube comprises providing an auxiliary device for generating variable magnetic fields in the tube neck, adjusting the auxiliary device to produce a field for converging the beams, activating the tube and determine data representing the direction and extent of the convergence error for each beam and then using this data to determine the polarity and intensity of magnetic poles of a structure for generating a permanent multipole magnetic convergence correction field. The auxiliary device may comprise a number of coils with adjustable currents. Data obtained from an auxiliary device can be stored in a memory, used immediately for controlling a magnetizing unit which magnetizes an annular structure, or converted into a code from which an annular structure may be derived or made up of a set of already magnetized parts. Fig. 1 shows an auxiliary device 5 (also Fig. 3, not shown), store 19 (e.g. a ring core memory) for data derived from coil current measuring unit 9, and control unit 11 for magnetizing unit 13 around convergence structure 15. Device 5 is subsequently replaced by structure 15. All these and other operations may be effected by automatic controller 17. The auxiliary device 5 and unit 13 may be initially side-by-side (Fig. 2, not shown). The magnetizing unit may also serve as an auxiliary device. The structure (15) (Fig. 4, not shown) may comprise ferrite ring (15B) and synthetic material support (15A) with ridge (15C), or (Fig. 6, not shown) a ferrite layer may be secured to the inner wall by a binding agent. The structure may alternatively be mounted on the rear of a deflection unit or on grids or cathodes in the tube neck. The structure may be magnetized one location after another (Fig. 8, not shown), core limbs (43, 45) being separable at faces (55, 57). The structure may include an annular synthetic support (61) (e.g. of polycarbonal) carrying eight ferromagnetic discs or inserts (63) in slightly elliptical holes (65). Width (d) is slightly smaller than height (h) which equal diameter (d<1>) of discs (63). Discs (63) may be magnetized before assembly. If the structure is selected from a series of permanent magnetic structures, preferably it is composed of a number of rings (e.g. a six pole field and a four pole field may be superposed).

Title: Improvements in or relating to electrical signal transmission systems
IPC: H04N7/045
Filed: 1960-04-08
Abstract: 952,607. Television; radio signalling; frequency-shift-signalling. L. DE WOLF. April 8, 1960 [April 10, 1959; March 11, 1960], No. 12617/60. Headings H4F and H4L. The video signal from a television camera 1, Fig. 1, is applied through an amplifier 4 to deflect a constant intensity beam 50 in a discharge tube 5 so that, in accordance with the instantaneous signal amplitude, it impinges on one of a line of electrodes 51-55, the signals resulting from the electrodes being applied to control gate stages in units 6a-6e through which oscillators each having a different fixed frequency are connected to a transmitter 7, 8. In effect the amplitude-modulated video signal is translated into a frequency-modulated signal for the purposes of transmission, the signal being capable of assuming five discrete frequencies only, each of which corresponds to a predetermined amplitude range of the video signal. Electrodes 51- 55 may be equal in size or may vary in size, e.g. according to a logarithmic distribution. More than five, together with a corresponding number of units 6, may be provided. Unit 6f operates at a sixth frequency different from the others and is employed to provide scanning synchronizing signals under the control of a unit 12 which also applies a signal over lead 12-5 to blank the beam of tube 5 during the production of the synchronizing signals. 2 is a control unit, 3 a monitor unit and 10 and 11 are power supply units. At a receiver, Fig. 2, the incoming signal is applied through pre-amplifiers 14 and 14<SP>1</SP> (which may be omitted) to selective amplifiers 16a, 16e, each of which is tuned to a different one of the frequencies employed at the transmitter. The amplifier outputs are rectified and applied to trigger associated multivibrators 17a-17e. The multivibrators all operate at the same frequency (determined by the numbers of elemental areas into which the reproduced image is to be resolved) but each produces a different amplitude output such that when applied via lead 18 and amplifier 19 to the grid of cathode-ray tube 20 the correct level of light intensity is produced corresponding to that represented by the frequency component selected by the associated amplifier 16. The frequency representing the synchronizing signal is selected by tuned amplifier 16f and controls line and frame scanning generators 22 and 23 in the conventional manner. More fully detailed circuits for carrying out the invention are described with reference to Figs. 3-8 (not shown). It is stated that the invention may be applied to a colour television system embodying two transmitters, one for a luminance signal and the other for a chromaticity signal. In a modified receiver, the multivibrator 17a-17e may be replaced by circuits which (a) convert the signals from amplifiers 16a-16e in voltage pulses, (b) amplify the pulses to amplitudes appropriate to the luminosities to be reproduced and (c) chop the pulses at a frequency determined by the number of elemental areas to be reproduced.

Title: Circular knitting machines and methods of producing knitted fabrics on such machines
IPC: D04B1/06
Filed: 1963-04-02
Abstract: A fabric is produced on a circular machine having double loops formed by drawing loops of two courses simultaneously through loops of a succeeding course.  This is achieved by first forming stitches by all of the needles with the loops being drawn over the normal sinker ledge or over the backs of the sinkers.  In either case the sinkers are then operated to ensure that the loops are brought in front of the sinker hooks Ph.  The needles are then raised so that alternate needles clear their hooks and the intervening needles retain their loops B within their hooks.  A yarn is then fed to all of the needles over the backs of the sinkers, Fig. 3, (not shown), or over the sinker hooks, Fig. 5, (not shown), and the needles operated so that the alternate needles form stitches whilst the intervening needles form loops F together with the previous course loops B.  The needles are then p  raised, Fig. 4, (not shown), (such that the loop F rides up the sinker hook Ph as the sinker is withdrawn and remains in the needle hook whilst the loop B is cleared below the latch.  The sinker is then withdrawn and the loops pass in front of the sinker hooks whereafter a further yarn is knitted to produce a succeeding course. This causes the loop F which has been tucked for one course to be drawn together with the yarn of the succeeding course through loops B of the previous course.  A course having double loops formed from the combined loops F and those of the new yarn is thereby formed.  To achieve the separation of the loops the sinker cams are modified as illustrated in Fig. 6, (not shown), and involves additional cams P1 and P4 whereby the sinkers are advanced, and a cam P6 which withdraws them to cause the loop F to ride up the sinker hooks. Alternatively the loops may be drawn over the top of the sinker hook and in a recess thereon and subsequently the sinkers may be advanced to separate the loops as illustrated in Fig. 13 or Fig. 17, (not shown). Where the needles cylinder is adjusted for quality control the needle cam can be simultaneously adjusted to maintain the correct relationship between the top of the sinkers and the needles when the needles are raised to clear their old loops B but to retain the loops F within their hook.

Abstract: 1464394 Controlling vehicle suspension height ROBERT BOSCH GmbH 25 March 1974 [24 March 1973] 13046/74 Heading B7D In a vehicle having a level-regulated rear axle 16 and an unregulated front axle 1, a level transmitter 4 sensitive to the front suspension height acts through a hydraulic transmission line 9 on a level regulator 10 having a second input from the rear axle 16 and means for damping the movement of the hydraulic fluid, the level regulator 10 acting to adjust the rear suspension height in response to a difference in the suspension heights at the front and rear. The level transmitter 10 includes a diaphragm piston 7 on which the front suspension acts through a lever 3 and a spring 6 and which is located in a chamber 8 corrugated to the line 9. The level regulator 10 includes a lower chamber 26 which is connected to the line 9 and communicates with an upper chamber through the damping means 41. A diaphragm piston 11 in the lower chamber 26 is subjected to rear suspension movements through a lever 14 and spring 12, and a spring- loaded diaphragm piston 35 in the upper chamber 34 is arranged to actuate micro-switches 17 controlling operation of a pressure generating unit 25 connected to rear suspension units 15. The fluid damping means 41 comprises valve plates 32, 33 mounted on a wall 27 dividing the chambers 26, 34 by rivets 30, 31 to control flow through a bore 27<SP>1</SP> in the wall, and a damping piston 36 carried by the piston 35 and projecting into a bore 37 in the wall 27 to form a small annular gap 38. With identical height changes at front and rear fluid only moves to and fro through the line 9 so that the micro-switch 17 is not actuated, but when the heights are unequal fluid passes through the wall 27 to displace the piston 35. To prevent operation of the microswitch 17 due to transient height changes fluid can pass only through the gap 38 until the piston 35 reaches the end of its stroke and actuates the micro-switch whereupon the damping piston 37 acts directly on tongues on the valve plates 32, 33 to open the box 27<SP>1</SP> so that rapid return of the piston 35 terminates the levelling operation quickly when the correct height is reached.
