Title: Improvements in or relating to integrating circuit arrangements
Inventor: HARKER MAURICE GEOFFREY
IPC: H03K4/04
Filed: 1947-02-18
Abstract: 644,634. Valve integrating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 18, 1947, No. 4623. [Class 40 (vi)] In a circuit employing a valve and integrating capacitor, a rectifier is arranged to be rendered conducting periodically to cause the output electrode of the valve to be brought to a predetermined potential in a sense opposite from that in which the potential changes during integration. A pulse generator 1 triggers a saw-tooth generator 2, the output being applied over resistor 3 to an integrating circuit comprising a valve 4 and feed-back capacitor 5. The pulse is also fed to diode 7 to raise the grid potential and thus lower the anode potential to a minimum once per cycle. The integrated saw-tooth appears as a parabolic wave at the anode. A symmetrical curve may be obtained by adding the integral of a constant potential, a resistor 9 being connected to a tap on the potential divider 8. A further diode may be added, Fig. 7 (not shown), to limit the downward excursion of the anode. In a modification Fig. 8 (not shown), the diodes are reversed, a negative triggering pulse being used. Specification 580,527 is referred to.
Patent GB-724681-A (GB)
Title: Reducing harmful effects of combustion products of fuels containing vanadium
IPC: F02C7/30
Filed: 1953-02-20
Abstract: 724,681. Gas turbine plant. SULZER FRERES SOC. ANON. Feb. 20,1953 [Feb. 23, 1952], No. 4759/53. Class 110 (3). [Also in Group XII] The harmful effects of burning a vanadium containing fuel oil in a gas turbine combustion chamber are reduced by introducing carbon monoxide into the combustion chamber and mixing it with the combustion gases produced therein in a region of the combustion chamber where combustion proceeds relatively slowly. It is stated that the presence of the carbon monoxide prevents the formation of vanadium pentoxide which accelerates corrosion and forms deposits which are difficult to remove. From tests it has been found that if the ratio by weight of carbon monoxide to vanadium in the combustion products is between 8 and 16: 1 that vanadium pentoxide is not formed despite the presence of a relatively large amount of free oxygen. The carbon monoxide may be formed by subjecting a portion of combustion gases to a secondary combustion. In another arrangement, the combustion of oil fuel and the combustion of coal are conducted in parallel in a flow of combustion air so that at least one of these combustions produces carbon monoxide and the combustion gases from both combustions are mixed together. Specification 667,371 is referred to.
Patent GB-967840-A (GB)
Title: Method and apparatus for forming glass beads
IPC: C03B19/10
Filed: 1963-02-06
Abstract: <PICT:0967840/C1/1> <PICT:0967840/C1/2> Beads of glass or other nitreous material are made by contacting a stream of the molten material with a diverging high velocity jet of gas or other fluid, which moves in a direction substantially parallel to the stream of molten material, and in sufficient proximity therewith to contact the stream and disperse it into a multiplicity of discrete particles which are shaped by surface tension into spherical form as they continue their movement along the path of the stream during cooling. A second fluid jet may be applied upstream of the high velocity fluid jet, and a third jet may be applied downstream of it.  The fluid may be e.g. air at room temperature or steam. In one embodiment (Fig. 1), molten glass is discharged from furnace 15 through aperture 21 in drain-out block 20, which is heated by burner 25.  The stream of molten glass is contacted by gas jets issuing from nozzles 30, 31 and 32 which are connected via pipes and conduits to manifold 42 in communication with pressure source 43.  Flow of gas is controlled by valves 39, 49 and 56.  Each nozzle is of flattened, rectangular cross-section (Fig. 2), the area of discharge opening of nozzle 31 being less than that of nozzles 30 and 32.  The glass stream is directed horizontally by the jet from 30 and directed slightly upwards and dispersed into particles by the higher velocity jet from 31. The particles are given extra lift and thus a longer arcuate path before falling by the upwardly directed jet from 32.  The diameter of the beads is varied by adjusting the velocity of the gas jet from nozzle 31.  The positions of the jets relative to the glass stream are varied by means of pivots 36, 46 and 53 on nozzles 30, 31 and 32 respectively.  The discharge opening of the drain-out block may be of rectangular cross-section, so that the stream of glass is flattened.

The components are interconnected over circuitry 42, connection solder pads 28, terminals 30, pin and socket connectors 32, and wires 34 into an external electronic function (not shown). Plate 14 comprises a block of, e.g. metal or epoxy glass which may be formed as a thermally conductive heat sink with corrugated fins cooled, e.g. by forced air. Substrate 12 of, e.g. alumina is cleaned, and multilevel resistor and conductor patterns are screened and fired thereon together with thick film printed conductors and multiple selective area seals. Via holes are provided to enable interconnection between multiple overlying conductive patterns, and the imposition of the circuit layouts may be computer controlled. A circuit pattern 42 may comprise top level conductors 44 and lower level conductors 46 formed together with hermetic sealing areas 48, to which ring frames 72 may be soldered. The substrate 12 is then bonded to plate 14 by, e.g. silicone adhesive, or brazed to a cooling fin, and discrete components 20, 21 are adhesively fixed and soldered to the substrate, after which jumper wires are soldered to the substrate solder pads 28 thereon, and to connection points, e.g. 30, 33. Chip components are then mounted within frame 72 and wire bonded to points 56 extending outwardly of the sealing areas 48. Pin connector 32 is then adhesively bonded or soldered to plate 14 with leads 34 bonded to pads 28 of the substrate, and the joints are sealed with epoxy adhesive. The thick film resistors may be adjusted by laser trimming. Thereafter covers, e.g. 64, 65 are soldered to the ring frames in nitrogen and leak tested, after which the entire microcircuit is encapsulated in polyurethane plastic. In fabrication of the selective area seals (Figs. 2a to 2f) area 48 is covered with a dielectric ring 66 to insulate leads 44 of the underlying circuit pattern 42, and a metal ring 68, e.g. of platinum and gold, gold, tungsten plated with gold or nickel is screened over ring 66 and tinned with solder at 70. A ring frame, 72, e.g. of iron nickel cobalt alloy, with a pretinned surface 74 is soldered to area 70, and an upper surface 76 is tinned at 78. A similar metal cover 80 flanged at 82 is then soldered to the ring frame, with hermetic sealing by solder closure of hole 84. Alternatively the cover 80 may be soldered directly to substrate 12.
