Abstract: 1400331 Direct reduction of iron ore THYSSEN NIEDERRHEIN AG HUTTEN-UND WALZWERKE 10 Sept 1973 [23 Sept 1972] 42414/73 Heading C7D [Also in Division F4] Reducing gases are supplied at a constant temperature to a shaft furnace, for the reduction of iron ore, by means of apparatus comprising two converters 2, each associated with a preheating heat exchanger 3, the reducing gases passing through a further heat exchanger 4 before entering the shaft furnace 1. At any time, one of the converters 2 is converting hydrocarbons to reducing gases, while the other is being heated up prior to producing reducing gases, the heating being effected by combustion of throat gases from pipe 11 and air from pump 13 supplied to burners 12. The ore may be in the form of lumps or pellets. The hydrocarbons may be converted to reducing gases by throat gas which is washed at 9 and condensed at 10 before use.

Abstract: 1437447 Regulating I C engines TEXACO DEVELOPMENT CORP 10 Sept 1973 [1 Nov 1972] 42517/73 Heading F1B I.C. engine control apparatus comprises first control means 4, Fig. 1 including injection means 1 for a pilot fuel spray which is ignited in a combustion chamber adjacent the injection means, means providing a variable mixture in the combustion chamber with a second control means 8 Fig. 1 including a fuel nozzle 7, a first pivoted triple linkage actuating an electrical switch means 23, 20 a second triple linkage comprising an arm 13 and a pair of slotted links pinned thereto one link 17 being pivoted to the control lever 14 of the first triple linkage and the other link being responsive to the electrical switch means. The mixture charge is supplied via intake tube 6, Fig. 1, the fuel flow from source 3 to nozzle 7 via control 8 being varied proportional to load up to the quantity required for an unthrottled charge with a F/A ratio (by weight) of 0.08. Nozzle 1, Fig. 2 (not shown) is supplied from source 3 and pump and control unit 3, the pilot charge being ignited by spark-plug 2. Above 0À055 F/A ratio pilot injection may be terminated since the premixed charge can be ignited directly. If the engine is operated at an output below that corresponding to an unthrottled premixed charge mixture strength i.e. leaner than 0À015 F/A ratio the fuel and/or air supply is controlled by terminating fuel delivery from nozzle 7 and operating on an increased pilot injection from nozzle 1 which is gradually reduced as engine output is reduced. Alternatively pilot fuel injection is maintained and a further progressive reduction of premixed charge fuel is made with simultaneous air intake throttling to maintain the premixed charge F/A ratio about 0À015. These operating modes are obtained by a linkage between control units 4, 8 and an air throttle 9, Fig. 6. The method is also applied to a two-stroke cycle ported intake, poppet valve exhaust uniflow engine Fig. 7 (not shown).

Title: Controller for systems having a transport lag
Inventor: MOORE RALPH HUGH
IPC: B65H23/188
Filed: 1968-09-06
Abstract: 1,236,433. Automatic registration. THORN AUTOMATION Ltd. Dec.4, 1969 [Dec.6, 1968], No.42662/68. Heading G3R. When the error in an error-actuated feedback control system exceeds a predetermined value the gain of a control amplifier is increased for a predetermined period and then reduced to zero for a further predetermined period. As applied to automatically maintaining longitudial register in a multi-colour rotary printing press for a web, error in the relative position of register marks printed with each colour is detected by photoelectric devices. As shown, a signal corresponding to this error is amplified at 2 and applied through a potentiometer 4, an attenuator 6, an amplifier 10 and a switch 12 to control a motor (not shown) correcting the error by adjusting the length of a loop of web between the stations at which the different colours are printed. To produce a gain suited to the transport lag, potentiometer 4 is set manually to correspond to the distance between the points of detection and correction of error and photo-resistive attenuator 6 is adjusted automatically in dependence on web speed. If the error exceeds a predetermined value, a trigger device 18 or 20 is operated, according to the sense, to cause a timer 28 to close a switch 16 for a fixed period so that correction is then applied at higher gain through an amplifier 14. Immediately following this period, an integrating timer 24 opens switch 12 so that there is no correction for a period which is dependent on the transport lag by virtue of a signal applied to timer 24 from a potentiometer 34 gauged to potentiometer 4 and supplied with a signal dependent on web speed. The timing sequence repeats until the error is restored between the limits whereupon normal correction takes place through amplifier 10. Amplifier 14 saturates to limit correction by large error signals and the signal from potentiometer 34 is also applied to a switch 32 to prevent adjustment of the gain if the transport lag is small.

Abstract: 993,726. Seaming non-metallic sheet material; laminates. TETRA A.B. Nov. 1, 1963 [Nov. 23, 1962], No. 43289/63. Headings B5K and B5N. In a method of heat-sealing a material comprising a body layer coated on both sides with thermoplastic material in which two layers of the material are compressed by clamping jaws and heat is transmitted from at least one jaw to melt the thermoplastic coatings so that the two inner coatings fuse together, the material is allowed to cool and then during release of pressure and removal of the jaws heat is again transmitted to melt the outer layers of thermoplastic, without attaching the inner layers, to prevent the outer layers adhering to the jaws. The heating of the jaw(s) is continued after removal until any thermoplastic material deposited thereon is decomposed. In an example a tube coated on both sides with a thermoplastic material such as polythene is heat-sealed transversely to form individual packages, the heating means being formed by a thin metal band on one of the clamping jaws heated by passing an electric current therethrough.

Abstract: 1303556 Conveyer system INTERNATIONAL BUSINESS MACHINES CORP 17 Sept 1971 [21 Dec 1970] 43345/71 Heading B8A A conveyer system comprises a plurality of conveyer sections arranged in tandem, a plurality of driving means, one for each conveyer section, and means for coupling each adjacent pair of sections, the coupling means including a clutch arranged so that an upstream conveyer section may drive a downstream section or a downstream section may overrun an adjacent upstream section. In the Figure, belts 3 and 5 form a conveyer section, driven by motor 25 and coupled to the adjacent upstream section which includes belt 1 via unidirectional clutch 31 so that the speed of belts 3 and 5 does not affect the speed of belt 1. If belts 3 and 5 are being driven slower than belt 1, however, motor 25 can be assisted by motor 23 via clutch 31. Downstream sections are thus driven at the same speed as or a higher speed than upstream sections. The system may be used to convey documents without buckling them.

Abstract: 1476394 Treating sulphur containing gases ITT INDUSTRIES Inc 8 Oct 1974 [15 Oct 1973 11 Feb 1974] 43475/74 Heading B1W [Also in Division G3] In a system using the Claus process for removing sulphur from flue gas containing hydrogen sulphide H 2 S the supply of additional oxygen (air) is controlled in response to a measurement by titration of the ratio of hydrogen sulphide to sulphur dioxide SO 2  in the gases downstream of the added oxygen. All or some of the flue gas is passed through a furnace 12 to which air is introduced through control valve 37. A proportion of H 2 S is oxidised to SO 2  and the resulting mixture is passed to a "coalescer" (heated baffles) 16  where a reaction takes place to yield molten sulphur at 18 and water vapour. As shown, the gases leaving the coalescer are sampled at 22; the sample passing through the devices indicated at 25, 28, 29 and 31 to produce electrical signals 32, proportional to the combination of H 2 S and SO 2  and 33, proportional to the H 2 S only. These are combined in a controller 34 (also Fig. 3, not shown) to derive the specified ratio, having regard to their molecular-weights, and the result is compared with a desired value set on a potentiometer (59), any difference causing appropriate rotation of a servomotor 38 coupled to the air valve 36. The servomotor control (Fig. 5, not shown) has rate feedback from a tachogenerator and the controller 34 may include a capacitor across an operational amplifier to give a desired delay in the response. In alternative arrangements the H 2 S and the SO 2  may be separately titrated (Fig. 2, not shown) and the ratio may be obtained by applying the H 2 S signal to a potentiometer whose slider is positioned by a motor controlled by the other titrater (Figs. 8 and 9, not shown). It is stated that the sample may be taken upstream of the coalescer and that the controller may be digital rather than the analogue type described.

Title: Process for producing metal oxides
IPC: C01G23/07
Filed: 1964-10-27
Abstract: Metal or Si oxides are produced by vapour phase oxidation at above 1000 DEG  F. of a volatile metal or Si compound in a frusto-conical reaction zone by introducing a cyclonically rotating mixture of the volatile compound, a fuel gas, and free O2-containing gas, into the small end of the zone and removing products from the large end.  The metal may be Ti, Zr, Sn, Al, or Fe.  The volatile compound may be a halide or oxyhalide, e.g. TiCl4, ZrI4, TiBr4, SiCl4, TiOCl3, or AlCl3.  The fuel gas may be methane, propane, butane, CO, S chlorides, or S vapour. Excess oxygen may be used.  The gases may be introduced tangentially in the same direction, either into a premixing chamber at the small end of the zone (Fig. 1, not shown), or into annuli surrounding the outer walls of the reaction zone, whence they flow into a premix zone at the small end, the volume of which may be adjusted by a plug (Fig. 2, not shown).  The gases may be fed in alone or mixed with each other or with inert gas, e.g. N2, He.  The spinning mixture enters the reaction zone at 75-350 ft./sec. The reaction zone may be preheated by initially introducing and igniting only fuel gas and O2, and the walls and small base may be cooled by water spraying or circulating water.  "Seed" materials, e.g. AlCl3, with a Ti compound, may be added tangentially or axially, in amounts of less than 10%.
