Title: Method of manufacturing an adherent pattern of particles of a substance on a substrate method of manufacturing a display screen of a colour display picture tube and a colour display picture tube having a display screen manufactured by the method
Inventor: STONE HENRY DERMOTT
IPC: H01J9/227
Filed: 1985-02-18
Abstract: A colour-display picture tube display screen was made by providing a display screen substrate with a layer of a photosensitive composition which becomes sticky upon exposure to light. A black film matrix pattern and patterns of phosphor elements were formed on the photosensitive composition layer by imagewise exposing the layer to light in accordance with respective patterns of the black film matrix and of the respective phosphor elements, dusting the exposed layer with cobalt oxide particles and with particles of the respective phosphors, and blowing off the non-adhering particles. The photosensitive composition layer was then removed from the display screen substrate by condensing vapour of an organic solvent on the display screen structure so as to dissolve the material of the photosensitive composition layer, and continuing condensation of the solvent vapour until pure solvent falls off the substrate. During condensation of the solvent vapour the display screen is disposed so that the condensate falls off the substrate. The photosensitive composition is soluble in the solvent but the light-absorbing material and phosphors are insoluble in the solvent. The black film matrix and patterns of phosphor elements are fixed to the display screen substrate, for example, using an inorganic binder such as potassium metasilicate.
Patent GB-2154773-A (GB)
Title: Single breakpoint linearization circuit
Inventor: BERTONE GREGORY ANTHONY
IPC: H03G3/20
Filed: 1985-02-20
Abstract: A circuit for linearizing an inherently non-linear signal utilizes piecewise linear approximation (Fig. 2). Drift and discontinuity problems normally associated with such circuits are obviated by inserting a non-linear circuit element D1 (usually a diode) in a feedback loop of an operational amplifier 18. An input voltage Vin and a reference voltage Vref are applied to a non- inverting input of operational amplifier 18, which has a diode 22 connecting the output thereof to the inverting input which is grounded. A second operational amplifier 26 has its inverting input connected to Vin and the inverting input of amplifier 18. The output of amplifier 26 is connected to the inverting input thereof by a resistor 30. The output Vo will vary linearly with the input Vin, the slope changing at a breakpoint VB, which is dependent upon the voltage Vref, since when V1 falls below zero, diode D1 to conducts. <IMAGE>

Title: Metal shuttering plate or element
Inventor: MATHIS HUGO
IPC: E04G9/02
Filed: 1985-03-20
Abstract: In metal shuttering plates/elements difficulties arise from the fact that contraction cavities are created on the surface of the concrete structure formed, since accumulated fluid cannot escape. In the case of the present shuttering plate, a single or multi-layered lining, which is manufactured from moisture absorbing or hygroscopic, filtering or draining material, is provided on the inside surface of the shuttering. By means of this step accumulations of fluid can be prevented, since excess fluid from the concrete mixture is absorbed or drawn off by means of the lining on the shuttering plate/element.
