Title: Cathode ray storage tube having a target dielectric provided with collector electrode segments extending therethrough
IPC: H01J31/12
Filed: 1976-05-12
Abstract: 1502737 Cathode-ray storage tubes TEKTRONIX Inc 12 May 1976 [28 July 1975] 19517/76 Heading H1D A C.R.T. storage target comprises an insulating support member 50a, 50b (Figs. 8a, 8b, respectively), an array of protrusions of dielectric beads secured to the support member, contive coating 52a (e.g. tin oxide) over the surface and the dielectric protrusions forming collector electrodes, and a dielectric storage layer 56a, 56b. The dielectric storage layer may be substantially continuous (Fig. 6, not shown). The collector electrodes may protrude beyond the outer surface of the storage layer. The beads may be micro-sized glass beads secured to the support surface by glass frit. A method of fabrication comprises applying a photopolymerizable layer having a dispersion of glass beads and vitreous frit, passing light through a photomask (Fig. 2, not shown), and washing away non-polymerized material, coating with conductive material, applying a photopolymerizable layer with a dispersion of phosphor particles, exposing to light through the support (Fig. 5, not shown) and washing. The glass beads (e.g. 10-20 Á diameter) preferably form conical configurations, or may be pyramidal, a triangular geometry. Photopolymerizable compositions are disclosed. Glass frit to glass beads is preferably 50-50 to ensure adhesion of the glass beads. The frit has substantially the same expansion coefficient as the faceplate, and other than glass beads may be used as long as fusion is obtained. Specified shrinking agents produce protrusions of a denser mass by rapid extraction of H 2 O, and the target baked at 400‹ to 500‹ C. in an inverted position to provide the conical configurations, the frit becoming liquidified prior to solidification. The tin oxide is applied by spraying. A further shrinking agent applied to the dielectric effects a retraction to expose more of the conductively coated protrusions (Figs. 6, 7, not shown) for enhancing secondary electron collection from the dielectric. Baking removes organic binders. Preferably the centre to centre spacing between protrusions is less than the beam diameter. The target may be curved (Fig. 9, not shown) rather than plane. The C.R.T. of Fig. 1 (not shown) includes one or more flood guns (34), producing low velocity electrons, focusing coating (42) for the flood electrons, focusing and collimating electrodes (44), (46) and (48), the latter also being an auxiliary collector for secondary electrons from adjacent target (32) and those secondary electrons not collected by the collector electrodes. Visible as well as electrical read-out is produced. Operational mechanisms are discussed.

Title: Improvements in or relating to grip-finger assemblies for labeling machines
IPC: B65C9/26
Filed: 1963-05-17
Abstract: 1,009,735. Labelling machine. GEORGE F. MEYER MANUFACTURING CO. May 17, 1963 [Feb. 12, 1963], No. 19709/63. Heading B8F. A grip-finger assembly for use in a labelling machine of the kind which comprises means for supporting an article in position to receive a gum-coated label and means for removing a label from a magazine and for applying gum to one face of the label is characterized in that the grip-finger assembly applies the label to the article while concomitantly subjecting the label to oppositely acting forces tending to stretch the label transversely. The grip-finger assembly comprises three levers 23, 29, 60, two of which 23, 29 are pivotally secured to a pivotally mounted base 20, the third of which 60 is secured to the base 20. The lever 29 carries body and neck label applying pads P 1 , P 2  each holding a label by means of suction applied through apertures X. The upper pad P 2  is mounted in a frame Z2 pivotally secured to the lever 29 and attached to the lever 23 by pivotally connected link 40 such that the frame Z2 can be tilted as the lever 23 approaches the lever 29. The lever 60 carries at its upper extremity a U-shaped frame D carrying auxiliary pressure pads Px, Py each containing apertures connected to a suction source. In operation a picker of the separable-blade type is coated with gum and, in turn, coats a label and carries it to a transfer pad P 1 , P 2  mounted on the grip-finger assembly, which is maintained with the surfaces of the pads P 1 , P 2  in the same plane. The base 20 on which the levers 23, 29, 60 are mounted is rocked so that the body label is applied to the article. As the base is rotated further the lever 29 causes the upper pad P 2  to be tilted parallel to the neck of the article and to apply the central portion of the neck labe (Fig. 6). As the lever 60 approaches the bottle the auxiliary pressure pads Px, Py on the frame D grip the label by means of the suction applied and as the arms of the frame D are forced apart as they pass round the article neck the label is tensioned laterally. When the label is applied around half the neck periphery the suction is changed to pressure and the gripfinger assembly is withdrawn. Conventional wiper devices are used to wrap the label fully around the article. The invention is described as applying a specific label (Fig. 21, not shown) to the neck of a champagne bottle carried on a conveyer. A similar grip finger assembly may be mounted opposite the first to provide a support for the article as the labels are applied.

Filed: 1948-07-28
Abstract: 671,331. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 12,1949 [July 28, 1948], No. 20086/48. Class 39 (i). A deflecting coil assembly comprises two pairs of saddle coils 1, 3 surrounded by a magnetic sheath 4, 5 having regions of different permeance around its circumference and means are provided for adjusting the relative permeance of the regions and/or the positions of the regions relatively to. the coils. This is obtained by constructing the sheath of one or more flexible sheet-metal sections 4, e.g. of iron, which overlap one or more similar sections 5, the permeance being greater where the sections overlap. Adjustment of the relative circumferential positions of the sections 4, 5 is such as to vary the permenace of the two overlapping regions in opposite senses, and in addition the position of the sheath as a whole may be varied with respect to the coils 1, 3. In a modification, the sheath may comprise four sections each extending rather more than a quarter of the way round the coil assembly. The overlap may be greater or smaller than that shown in the drawing, e.g. 45 degrees. All the sections of the sheath may be made to conform to a cylindrical surface by using rigid material or by employing suitable spacers or formers. For example, four partially cylindrical elements may be arranged with their centres 90 degrees apart and with a degree of overlap of somewhat less than 45 degrees. The coils are separated by insulating spacers 2, 7. The coils 3 may be of larger diameter than coils 1, as shown, or alternatively coils 1, 3 may be of similar dimensions in which case their active axial conductor bundles interfit. When the sections 4, 5 have been adjusted to the optimum position they are secured in this position by adhesive tape. The sections 4, 5 may each comprise a plurality of layers of materials of different permeabilities, and the layers may be of different thicknesses. For example, in a television pick-up or reproducing tube the sections are each made of two layers which respectively have optimum permeability and resistivity at the line and frame frequencies.
