Abstract: 1,127,529. Controlling burners. S. J. HODGKISS. 7 Sept., 1967 [15 June, 1966], No. 26768/66. Heading F4T. [Also in Division G1] A control circuit for a fluid fuel burner arrange - ment having a main burner and a pilot burner includes a master switch B1, a delay circuit comprising a normally closed contact A1 of a relay A, a rectifier 4, a resistance 5 and capacitor 6 having connected in parallel with it a circuit including a neon lamp 7 and the coil of a relay B effective to open the master switch B1, a second sub-circuit comprising contacts A2, A3 of the relay A connected to a winding 8 of the ignition system and to the solenoid 9 of a valve controlling the main burner fuel, a third subcircuit comprising the solenoid 10 of a valve controlling the pilot burner and a fourth sub-circuit which includes the primary 11 of a transformer of which the secondary 12 is connected to a rectifier 13 and capacitor 14, a transistor 15 and the winding of relay A being connected across the capacitor 14, the base of transistor 15 being connected to the emitter through a resistor 16 and to the collector through a photoresistor 17 responsive to the light of the pilot burner flame and the winding of relay A. Current is supplied to the master switch via a thermostat responsive to a call for heat and, the switch being closed, the ignition will be energized, the pilot burner valve opened and the time delay circuit energized. If the pilot burner lights the photoresistor 17 allows the transistor to conduct and energize relay A to leave the pilot alight, open the main fuel valve and de-energize the time delay circuit. If however the pilot fails to ignite the time delay circuit will eventually function to energize relay B and open the master switch B1 until manually reset.

Title: Method and means to generate controllable thermonuclear reactions in industrial scale and utilization of the released energy
IPC: H05H1/22
Filed: 1958-08-22
Abstract: 886,404. Nuclear fusion reactors. CHRISTOFILOS, N. C. Aug. 22, 1958, No. 27032/58. Class 39(4) A method of producing a controlled thermonuclear reaction comprises producing in an enclosed evacuated volume an elongated substantially axially symmetrical magnetic field having a central region of uniform intensity and end regions of increased intensity, injecting and trapping electrons of relativistic energies to form a generally cylindrical layer of electrons rotating about the axis of the magnetic field thereby creating an electromagnetic containment field pattern, and introducing thermonuclear fuel into the volume to enter the field pattern to be ionized and heated to provide a plasma confined in the field pattern. The reactor shown in Fig. 2 comprises a cylindrical vessel 11 provided with evacuation conduits 13 and disposed inside a radiation shield 14. The vessel may be provided with a cooling jacket fed with water which is converted into steam which is used to generate power. The vessel is surrounded by a solenoid 23 constructed of water cooled coils and connected in series with similar end coils 24; the solenoid 23 produces a uniform field within the vessel, and the end coils 24 produce a stronger field at the ends of the vessel. High energy electron beams are projected into the vessel through injection tubes arranged tangentially of the vessel and in planes slightly inclined to the plane normal to the axis of the vessel. The electrons are injected into a first trapping region between a -pair of coils 27, 28 and transferred to the second trapping region between coils 28, 29, and then form a hollow cylinder in the region between coils 29 and 31. The coils 27, 28, 29 may be fed with a current varying as I 0 (1-cos #t), the current in coils 28, 29 lagging by 60 degrees and 120 degrees the current in coil 27. Injection is initiated by actuating the electron accelerators when the current is zero in coil 27, so building up the electron layer whilst at the same time neutral particles, e.g. of deuterium, are injected to build up a plasma. After the starting period the injection of neutral particles is continued and the magnetic field is slowly increased over a period of several minutes to its maximum value. Part of the energy evolved appears as heat at the walls-of the vessel and is removed by the cooling jacket, and part of the energy may appear in the form of an energetic beam, mainly of electrons, through the tubes 13. This beam can be guided through a transformer to generate electricity or can be used to heat a compressed gas in the throat of a Venturi tube in ram jet devices employed for jet propulsion.

Title: Glass
IPC: C03C13/04
Filed: 1963-07-09
Abstract: A glass has a liquidus temperature of at least 80 DEG  F. below the temperature at which the logarithm to the base 10 of the viscosity in poises is 5, refractive index below 1.5, fibre softening point below 1425 DEG  F., and coefficient of thermal expansion of less than 80 x 10-7. The glass consists essentially of, by weight, 35-50% SiO2, 3-11% Al2O3, 22-38% B2O3 and 15-25% Rb2.  The glass may form the matrix in which rods or fibres of a glass of different composition, e.g. 29.3% SiO2, 61.7% PbO and 8.0% BaO, are embedded.  The composite structure may be formed by enclosing rods in tubes of the matrix-forming glass, assembling, heating and pulling, the resultant structure comprising many fine glass fibres in parallel orientation embedded in a matrix.  For the purposes of fibre optics, the refractive index of the fibre glass should be greater than that of the matrix glass.
