Title: Electromagnetic Coarse Positioning System for the Electron Beam of a CRT
IPC: G09G1/04
Filed: 1967-07-26
Abstract: 1,196,313. Cathode-ray tube deflection circuits. SPERRY RAND CORP. 26 July, 1967 [31 Aug., 1966], No. 34418/67. Heading H4T. The two coils of the push-pull deflection yoke of a cathode-ray tube are connected via a switching arrangement to a single-ended digital type deflection waveform generator such that deflection current flows in one coil to step the beam from one edge of the screen towards the centre and then flows in the other coil to step the beam from the centre towards the opposite edge of the screen. Thus, as shown in the drawing, which is concerned with the X deflection system (the Y deflection system operating in a similar manner) deflection currents of a magnitude determined by binary weighted resistors 30, 32, 34, 36 and forming the analogue equivalent of the condition of n - 1 stages of the X register as the stages are sequentially set flow through either deflection coil 6 or deflection coil 8 of the push-pull yoke in accordance with the state of the nth stage of the register. The latter, in addition to conditioning the AND gates of the logic circuit 28, controls transistors 42 and 46 such that they are alternately cut-off thus causing respective transistors 2 and 4 to conduct alternately and complete the path for the deflection currents from + E to the common point 40. When the nth stage is " set " all the earlier stages are re-set and the register is again incremented in sequence. With this arrangement a count of 1110 or 0001 (considering n = 5) is indicative of zero beam deflection (i.e. the beam is in the centre of the screen) and to avoid this condition a resistor 38 is included to provide a fixed bias current for the deflection coils of such value that the " centre " position when the coils 6 and 8 are respectively operative is one-half of a unit step to the left and to the right respectively of the screen centre. To ensure linearity of deflection the voltage at point 40 is held constant independently of the magnitude of the deflection current by means of transistors 52, 54 the emitters of which are tied to a reference voltage 56 and which operate such that as the deflection current through transistors 2 or 4 increases the voltage drop across their base-to-emitter circuit also tends to increase thus causing the voltage on the bases of transistors 52 or 54 to tend to decrease resulting in an increase in the voltage from sources 48 or 50 on the bases of transistors 2 or 4 respectively so that the voltages on the emitters of the latter are held constant.

Abstract: 408,183. Uniting by fusion. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Humberstone, J. H. ; 1050, Park Avenue, Schenectady, New York, U.S.A.) Dec. 8, 1933, No. 34620. Convention date, Dec. 23, 1932. [Class 83 (iv).] A metallic arc welding electrode is covered with a tape of fibrous material 3 impregnated with flux 2 and folded longitudinally about the core with its edges abutting and parallel to the axis of the core. The core and tape may be drawn through a bath of flux paste and through a die submerged therein in the manner described in Specification 178,926, [Class 83 (iv)], so as to obtain simultaneously an undercoating of flux and a covering of fibrous material. The flux may consist of ferromanganese, talc, felspar and sodium silicate as described in Specification 394,610. The tape may consist of a number of parallel warp threads 4 of cellulosic material such as cotton, with wefts 5 of similar material which may be of smaller diameter than the warps and prevent the material from stretching. The flux enters the interstices of such open-work fabric. After the flux and tape have been applied the flux is dried by natural evaporation or baking, preferably from the inside out by heating the core prior to applying the flux or generating heating currents in the core by passing the finished electrode through a coil energized by a high frequency current. For hand welding the electrode is bared at the end, but for automatic welding incisions are formed in the coating or a portion thereof removed.

Title: Method and apparatus for measuring the combustibles and oxygen constituents of a gas
IPC: G01N27/409
Filed: 1972-07-25
Abstract: 1393396 Electro-chemical analysis WESTINGHOUSE ELECTRIC CORP 25 July 1972 [20 Aug 1971] 34666/72 Heading G1N [Also in Division G3]  Both the combustibles and oxygen constituents of a gas are measured. A sample of gas from a flue F of a burner is applied in a counter flow pattern to a combustion sensor 10 including a catalytic thermopile sensing element 12 and heater element 14, Fig. 3 (not shown). The element 12 generates an e.m.f. indicative of the total content of the minority constituent of the sample gas, and which is completely reacted in the chamber 10 and is oxygen in an oxygen rich sample or combustibles in a fuel rich sample. After reaction the gas flows through a solid electrolyte oxygen titration cell 20 and a solid electrolyte oxygen monitoring cell 40 the outside of which is surrounded by a reference gas such as air. In the event of an oxygen rich sample the output from 40 will be in the range 0-200 mv whereas in the event of a fuel rich sample when the oxygen has been depleted in the chambers 10 and 13 the output of cell 40 is in excess of 800 mv. If the e.m.f. generated by the cell 40 exceeds a predetermined set point value between 200 mv and 800 mv indicative of a combustibles rich condition a feedback signal FB is transmitted to a D.C. voltage excitation circuit 50 which applies a D.C. potential across inner and outer electrodes 22, 24 of cell 20 proportional to the difference between the e.m.f. generated by cell 40 and the set point value. This potential establishes a flow of oxygen from the oxygen reference outside the cell into the sample gas flow. This pumping action continues until the oxygen content of the sample gas as measured by assembly 40 is sufficient to establish a predetermined relationship between combustibles and oxygen. Thus the current measured by ammeter A is a direct measure of the excess combustibles in the gas. Electrical output signals from the combustion sensor 10, the output signal of assembly 40 indicative of excess oxygen and indicated on voltmeter 60 and the current measurement from ammeter A indicative of excess fuel are fed to computer circuit 70 to provide measurements of the total oxygen and combustibles content of the sample gas and which are used to control a fuel-oxygen supply system 80 in order to obtain the desired fuel-oxygen ratio in a burner B of furnace F.

Title: A process for obtaining threads from protein colloids in solution
IPC: D01F4/00
Filed: 1929-11-25
Abstract: <PICT:0342821/IV/1> Viscous solutions of protein substances are employed for the manufacture of artificial threads by causing a drop of the solution to protrude by gravity from a very large orifice, and drawing a thread from the drop which is constantly renewed and maintained under conditions of temperature and humidity so that change of either of these two factors causes the solution to congeal. Apparatus for carrying out the process may comprise a tube T having an orifice of several square millimetres cross-section from which a drop of the solution protrudes and is drawn out to form a filament in an evaporative atmosphere.  The solution may be heated if desired. The protruding drop G and the newly-formed filament are enclosed in a casing C in which the temperature and humidity are controlled.  Gas, or solvent vapour which may be water vapour in the case of water-soluble proteins, is introduced into the casing by means of a tube D.  The presence of solvent vapours prevents the formation of a solid film on the surface of the drop G.  In order to start spinning, the first drop may be collected on a solid support which is moved until the filament drawn out comes in contact with a roller B upon which it is wound.  The filament continues to draw out the drop G without interruption.  Alternatively the first drop may be allowed to grow until it drops and carries with it an appendant filament which is received on the winding device.  In order to prevent the drop from being deposited on the winder, the latter is placed some distance from the vertical GV, and the filament is blown towards it by a horizontal jet of compressed air J.  The drop carried along by its inertia breaks the thread and continues to fall.  The detachment of the drop after the filament has been received on the winder may be facilitated by introducing solvent vapour with the jet J, so as to soften the filament.  The diameter of the filament is dependent on the speed of the winding device and the speed of supply of the solution.  Very fine filaments can be spun whilst the use of fine bore spinning orifices is dispensed with.
