Title: Defelction circuit for television receivers
IPC: H04N3/237
Filed: 1973-08-24
Abstract: 1443038 D.C.-D.C. converting INTERNATIONAL STANDARD ELECTRIC CORP 24 Aug 1973 [9 Sept 1972] 40252/73 Heading H2F [Also in Division H4] In an arrangement for correcting horizontal pincushion distortion in television receivers the D.C. operating potential for the vertical deflection circuit is derived by rectifying and filtering a voltage developed across a winding on the horizontal output transformer the filter being so proportioned that the current drawn by the vertical deflection circuit varies at the vertical deflection frequency and modulates the current flowing in the horizontal deflection circuit to produce the required correction. As shown, the voltage developed across a centre-tapped winding II on the horizontal output transformer Tr is full-wave rectified by the diodes and filtered by capacitors 3 which are so proportioned that the circuit resonates at the horizontal frequency and provides at terminals 6, 7 the D.C. operating potential for the vertical deflection output stage V-EST. which is connected to the vertical deflection coils AS. Thus the current drawn by the vertical deflection output stage varies at the vertical deflection frequency and via transformer Tr modulates the current flowing in the horizontal output stage to provide the required correction. The symmetry of such correction may be adjusted by resistor 5 and capacitors 4. In order to enhance the correction the deflection coils are shunted by branch circuits 12, 13 including oppositely poled diodes which operate to cause an increase in the current drawn from the horizontal deflection stage at the beginning and end of each vertical period.

Abstract: 1444346 Honeycomb laminates DUFAYLITE DEVELOPMENTS Ltd 27 Nov 1973 [31 Aug 1972] 40395/72 Heading B5N [Also in Division E1] In an expanded structural honeycomb material of which the walls of the cells are coated with, or of which the cells contain an intumescent material for filling the cells when exposed to fire, the cells have walls formed to permit gaseous flow from cell to cell. In a preferred embodiment, the walls are so formed by notching the honeycomb material in the unexpanded state on at least one face thereof. The structural honeycomb material may be laminated between two adhesively secured facing panels. In the embodiment of Fig. 1, a building panel comprises frame members 1, 2, 3 and 4 and optionally cross-members 5 and 6, the members 1 to 6 being formed of flax boards, the shives of which are bonded with a urea-formaldehyde resin, the honeycomb member 7 being formed of thick paper coated with an intumescent ureaformaldehyde paint containing nitrocellulose, a blowing agent and inert fillers, the member 7 being faced with facing panels 8 and 9. Frame members 2 and 4 at least are formed with a deep central recess 10 and with rebates 11 and 12 which co-operate with the facing panels 8 and 9 to define further recesses on either side of recess 10. In Fig. 2, a pair of the panels is shown in butt-jointed relationship with the joint bridged internally by strips 13, 14, 15, e.g. of asbestos or hardboard dimensioned to mate within the recesses. In Fig. 3, the honeycomb material terminates at 16, short of the edges of the facing panels and the joint is bridged by a strip of intumescent coated honeycomb material 17 laminated between strips 18 and 19, e.g. of asbestos or hardboard.

Abstract: 958,181. Thermometers. ROSEMOUNT ENGINEERING A.G. Nov. 5, 1962 [Nov. 3, 1961], No. 41800/62. Headings G1D and G1N. The temperature of a moving surface 10 is measured by bringing a fixed surface 102 close thereto so that there is a continuous gradation of rate of flow of air or other gas between the two surfaces, the temperature being measured of surface 102 at 121 and at a point 120 between the surfaces 10, 102, the temperature of surface 10 being deduced therefrom. The air or gas flow may be laminar or turbulent and if the movement of surface 10 is not sufficiently rapid a jet blast or fan may be used to induce a turbulent flow between the surfaces. The point 120 may be midway between the surfaces, the difference of temperature between points 120,121 being doubled to give the temperature difference between surfaces 10,102. The temperature may be measured by resistances connected in a bridge circuit having a meter 140 connected across the arms. The surface 102 may be heated or cooled, by fluid passed through a pipe, so that it is at, or very close to, the temperature of surface 10. To perform this automatically, the surface 102 is provided with an electric heater 150 which is switched on by contacts 158a, 162a when the arm 158c of a temperature recorder 157 connected to the meter 140 moves upwardly due to the temperature of surface 10 increasing above that of surface 102. When the temperature of surface 10 falls, arm 158c moves downwardly to contact 162b and thus slide member 161, carrying contacts 162a, 162b, downwardly, the contact 162b not being connected in any circuit so that heater 150 is switched off and surface 102 is allowed to cool. The surface 102 may be provided with downwardly extending side flanges 114 and the temperature detector 120 protected by guards 116. The rear surface may be lined with insulation.
