In a colour television receiver of the three colour type, a plurality of cylindrical electron lenses are formed adjacent the multi strip target by a parallel wire grid 27, Fig. 2, and a conducting coating, preferably of aluminium, on the phosphor strips, so that the beam is brought to a line focus on a phosphor strip, and the beam is switched from one colour strip to another by means of electrostatic deflecting means within the tube which deflect the beam away from and then back to the axis so as to vary the angle of approach to the wire grid, and further deflecting means are provided for scanning the beam over the target. In one form, Fig. 1 (not shown) there are three successive pairs of deflecting plates, the first two pairs of which, in order from the cathode, produce the scanning deflections, and the first and third pairs the colour control deflections. The first and third pair of plates are connected via a potentiometer so that the ratio between the opposite colour deflections can be adjusted. In a modification, Fig. 4, pairs of plates 19<SP>1</SP>, 19" are supplied with equal and opposite colour control voltages, and the beam is redirected by magnetic focusing coil 70. Scanning coils 71, 73 are provided. The red, green and blue phosphor strips 29, 31, 33, Fig. 2, are formed as coatings on transparent glass support 25, which may or may not be the end wall of the tube, and the aluminium coating also serves as a reflector. The stainless steel or nickel grid wires 27 are carried from rectangular metal frame 37, which also supports screen plate 25, by means of spring fingers 38 spot welded in grooves in the frame. If the wires are of steel they may be spot welded direct to the frame under tension. The beam may be blanked during transitions between colours but this is not in general necessary. The transmission may be of simultaneous or of field, line, segment or dot sequential type. The direction of scan may be parallel to the grid wires or diagonal in Fig. 4 but cannot be diagonal in the form of Fig. 1 (not shown).

Title: Method and apparatus for separating or filtering solids from liquids
IPC: B01D33/067
Filed: 1962-03-06
Abstract: 998,140. Centrifugal strainer separators. AJEM LABORATORIES Inc. March 6, 1962 [March 9, 1961], No. 8585/62. Heading BID. Solids in slurry introduced at 12, Fig. 1, are prevented from adhering to the outside of a centrifugal drum screen 14, and are repelled therefrom by the speed of its rotation. Filtrate is discharged through a pipe 30 communicating with the drum interior, while concentrated solids are discharged at 34. In Fig. 4A the drive shaft 16b of the drum screen 14b is surrounded by a hollow shaft to which are secured the vanes of a two-stage centrifugal pump 35b for withdrawing the filtrate. The shafts may be rotated at different speeds. In Fig. 8 (not shown), filtrate is withdrawn by a centrifugal pump, and the liquid flow drives the drum screen by reaction against a set of vanes mounted in the top of the drum. The surface of the drum screen may take various forms. To improve its repulsion characteristics, the screen may be formed wtih vertical corrugations; or it may have the shape, in plan section, of a ratchet wheel ; or it may be surrounded by an array of nearly-tangential inclined vanes secured between the upper and lower end-plates ; or it may have vanes secured just inside its periphery but spaced therefrom, these serving also to improve the filtrate flow. When the drum screen is frusto-conical it may be located either way up. The rate of flow may be increased by providing vertical rods extending between the drum end plates near the drum axis. The drum may be positioned horizontally, and the liquid flow path from the slurry inlet to the sludge outlet may be tangential to the drum ; the direction of flow may be in the same sense as the direction of rotation of the drum to assist solids repulsion. There may be inclined radial vanes across the inner (withdrawal) end of the drum, when it is positively driven, to form a pump, in series with the main pump provided in the filtrate discharge conduit. Specifications 754,585 and 804,997 are referred to.

Abstract: 1,241,391. Knitting. WIRKMASCHINENBAU KARL-MARX-STADT VEB. 19 Feb., 1969, No. 9014/69. Headings D1C and D1K. A single cylinder circular machine is equipped with a semi-circular welt dial 1 pivotable about axis 2 for transfering loops from one side of the cylinder to the other e.g. during knitting a closed toe. When the dial is swung, bits 5 are retracted-bits adjacent the axis to a lesser extent than the remainder. To knit a closed toe, yarn is fed to half the complement of needles and the sinker loops held on the jacks Reciprocatory knitting with narrowing commences when sufficient courses have been knitted, the bits are retracted so that as the dial is pivoted to the vertical position they clear the sinkers. The butts 7 of the edge bits are stepped so that they are withdrawn just sufficiently to clear the adjacent sinkers. This allows the edge bits to hold one loop only and prevents eyelet formation at the sides of the toe. After reciprocation with widening the dial is pivoted through a further 90‹ so that the held loops can be transferred to the other half of the needle complement.

Title: Improvements in tennis rackets
IPC: A63B51/12
Filed: 1926-04-06
Abstract: 262,638. Way, H., (trading as May & Co., H.). April 6, 1926. Rackets.-The strings of tennis rackets, at the points where they pass through the inner surface of the frame, are enclosed, in pairs, by rings which are free to move laterally so as to distribute the tension evenly between the two strings. As shown in Fig. 6, each pair of strings passes through a ring d and the string hole is flared so as to allow the ring to adjust itself laterally. The rings d may be replaced by a cord passing along the interior of the frame and knotted around each pair of strings, the cord being impregnated with oil or varnish after it has been tied in. Flanged rings d'. Fig. 10, may be used. In making a racket with diagonal stringing, Fig. 4, the rings d may be arranged in four groups m, m, n, n, the intermediate portions g, g<1>, o, o<1> of the frame being strung without the use of rings. In the racket shown in Fig. 1, in addition to the rings d a continuous cord c is knotted into the mesh. In a modification applied to a diagonally-strung racket the cord c is in two portions. In Fig. 8 is shown a means for securing the loose ends of the string- ing. The frame is provided with grooves h intermediate the string holes i, and the loose end b<1> of the string is passed along the grooves and tightened so as to become wrapped around the strings b<2>, b<3> and is then retained by friction. The stringing may be tightened by pulling the rings away from the frame, for example by means of a cord t, Fig. 13, passing over the rings and round the adjacent intersections of the strings. In a modification, the tightening is automatically effected by a spring located between two rings encircling a pair of strings. In a further modification, Fig. 16, the rings d<1> are forced away from the frame by the wedging action of a wrapping of cord w which may in addition be pulled down by a cord x.

MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Roberts, W. van B. ; 155, Hodge Road, Princeton, New Jersey, U.S.A.) March 21, 1930, No. 9115. Convention date, March 29, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] To prevent re-radiation of the local oscillations in a superheterodyne receiver, the local frequency required for " beating " with the signal frequency is derived from two local oscillators (instead of one), both being set to a frequency well outside the broadcast range. The intermediate-frequency stage IFA of a supersonic receiver is tuned say for 100 kilocycles, and one local oscillator 1 is set to generate at 2000 kilocycles. Then if a signal on 500 kilocycles is to be received, the second local oscillator is adjusted either to 2400, 2600, 1600, or 1400 cycles, any of which settings will give the desired intermediate frequency of 100 kilocycles.
