Patent GB-1375417-A (GB)
IPC: C21C5/56
Filed: 1971-11-24
Abstract: 1375417 Steel production CENTRO SPERIMENTALE METALLURGICO SpA 24 Nov 1971 [5 Dec 1970] 54503/71  Heading C7D In the production of steel by melting and refining a carbon-containing charge in a vertical converter, the charge comprising solid materials such as steel scrap and iron in pigs, the heat necessary for melting and overheating is supplied by primary combustion of liquid or gaseous hydrocarbonaceous fuel from a burner and by secondary combustion of the partially burnt gases and by combustion of coke. In the latter part of the melting stage and the entire refining stage a reducing atmosphere is maintained in contact with the charge and an oxidizing atmosphere is maintained in the converter out of contact with the charge for the secondary combustion and to supply heat to the charge by radiation. An oxygen-fuel burner is progressively lowered into the converter as melting and combustion of coke proceeds and oxygen is introduced through a secondary lance into the upper part of the converter for the secondary combustion of partially burnt gas. The converter may be rotated about its vertical axis, slowly before the introduction of secondary oxygen and faster thereafter.

Abstract: 1492535 Autogeneously bonded fabrics; dimensionally stabilised fabrics SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 25 Nov 1974 [26 Nov 1973] 54680/73 Headings D1K, D1P and D1R The fibres of a textile article are bonded by applying a foam prepared by operating a composition comprising sulpholane (tetramethylene sulphone) or substituted sulpholanol containing up to 8 carbon atoms in the substituents and optionally one or more organic diluents, 8 to 50% of (based on the weight of sulpholane plus diluent) of water, at least 0.0251 (based on the weight of sulpholane, diluent and water) of a surfactant, and optionally coconut oil diethanolamide as foam stabiliser, and heating the textile article so as to activate the sulpholane (a latent solvent) to bond the fibres. In the examples the foam is applied by a doctor blade or rollers to the back of a tufted pile fabric to stabilise the pile. It may also be used to laminate fabrics together or to bond the fibres of woven, non-woven and knitted fabrics by through bonding or surface bonding. The treated article is dried then heated at 60 to 120‹C for 1 to 30 minutes to produce bonding. The fabrics may be formed of staple fibres or continuous mono or multifilaments. The bondable fibres or filaments may be homo or cc polymers of acrylonitrile containing up to 65% of vinyl chloride, vinyl acetate, vinylidene chloride, methyl acrylate, methyl methacrylate, vinyl pyridine or styrene, homo or copolymers of vinyl chloride or vinylidene chloride with any of the above monomers, or cellulose diacetate, triacetate or acetobutyrate. Up to 75% of the fibres may be wool, polypropylene or other non-bondable fibres. The substituted sulpholanes specified are 2 - methyl, 3 - butyl, 3 - isopropyl, 3 - n - hexyl, 3 cyclohexyl and 2 - methyl - 4 - butyl sulpholane. The. organic diluent may be diethylene glycol, 'triethylene glycol, dibutyl phthalate or triethanolamine in the ratio 90:10 to 5:95 diluent: sulpholane. The surfactant may be a C 8-16  alcohol ethoxylated with 2- 20 moles ethylene oxide, an ethoxylated fatty acid, an alkylaryl polyether alcohol, a sulphated alcohol, sulphated olefin, an alkyl aryl polyether sulphate, a sulphated or sulphonated amide or an alkyl aryl sulphonate.

Title: Method for the Fabrication of Integrated Circuits.
IPC: H01L27/06
Filed: 1966-12-08
Abstract: 1,162,500. Semiconductor devices. TEXAS INSTRUMENTS Inc. 8 Dec., 1966 [28 Dec., 1965], No. 54945/66. Heading H1K Integrated circuits comprising components formed in islands of semi-conductor material isolated and supported by insulating material are produced by forming the components in one face of a wafer of semi-conductor material, forming grooves between the components by etching from the other face of the wafer, providing a mask between the individual circuits, depositing insulating material in the etched grooves, and scribing and breaking the wafer along the lines of the mask. Each circuit may comprise two transistors and two resistors produced by forming the components (2, 2<SP>1</SP>, 3, 3<SP>1</SP>) in one face of a wafer of semi-conductor material by diffusion, Fig. 1 (not shown), and depositing conductive tracks (7) over an apertured layer (4) of silicon oxide to interconnect the components of each circuit, Fig. 2 (not shown). The face of the wafer in which the components are formed is then mounted on a ceramic or glass plate (9) by means of a "hold-down" plastic (8) and the opposite face of the wafer is masked with a layer (10) of silicon oxide in which apertures (45, 45<SP>1</SP>) are selectively formed, Fig. 3 (not shown). The wafer is then etched using an etchant which selectively attacks the semiconductor material, e.g. CP8 (5 parts nitric acid, 3 parts hydrofluoric acid) to form grooves (11<SP>11</SP>, 11<SP>111</SP>) surrounding the components of each circuit, and a layer (12) of borosilicate glaze is evaporated on to the wafer, Fig. 4 (not shown). A mask (50, Fig. 5) of plastics material is stuck to the surface of the wafer to cover parts of the surface between adjacent circuits, and the grooves are filled with an insulating mixture comprising sodium silicate, alumina, and silicon dioxide (quartz), in a liquid form which is allowed to solidify. A layer of the insulating material also covers the parts of the surface exposed by the mask 50, and the material in the grooves electrically isolates the components of each circuit while mechanically supporting them, Fig. 6. The mask (50) and the " holddown " plastic (8) are removed using solvents and the wafer subdivided into individual circuits by scribing and breaking along the lines exposed by the removal of the mask. The purpose of the mask is to ensure that the insulating material does not have to be broken during the subdivision process. The mask (50) may be of " Mylar " (Registered Trade Mark) tape or of an acetate or paper tape. The mask may also comprise a photoresist or a deposited or grown semiconductor material, and in these cases need not be removed before scribing and breaking the wafer. Parts of the components may be produced by epitaxial deposition instead of by diffusion, further components such as metal film resistors and MOS FETs may be deposited on the oxide layer.

Title: Spectrum Analysis Apparatus
IPC: G01S7/483
Filed: 1967-12-15
Abstract: 1,172,927. Testing spectral distribution. INTERNATIONAL BUSINESS MACHINES CORP. Dec. 15, 1967 [Jan. 13, 1967], No.57207/67. Heading G1U. An apparatus for testing the spectral distribution of the frequency components of a signal waveform incorporates a number of bandpass filters 27-31 each tuned to a different bandwidth within a frequency spectrum of interest, to the common input line 24 of which the waveform is applied. The filters produce D. C. outputs representative of the amplitude of the corresponding waveform components. These outputs are adjusted by potentiometers 32-36 such that for a predetermined waveform the outputs from all the filters are the same. Comparators 44-48 compare the individual outputs from the potentiometers one with another to provide an output indication whenever a difference between the adjusted output signals of any two filters is detected. The arrangement is used in association with a device 10 for examining the spatial distribution of incident light, the device consisting of a combination of a photo-diode J1 and a simple diode J2 connected in opposition, across which a longitudinal potential gradiant from battery B to earth is applied. The arrangement is subjected to a voltage sweep from a generator 22, to provide a waveform on line 20 whose time variation corresponds to the spatial distribution of the incident light. This waveform is differentiated before being passed to the line 24, since the response is the summation of the photo-currents in the activated device, and the resulting signal analysed by means of the arrangement described above. The number of comparators required in the arrangement of Fig. 1 if a number of harmonics are to be examined will be considerable. The arrangement may be simplified by connecting the adjusted outputs from the filters in parallel to both positive and negative analogue OR diode circuits which respectively produce outputs corresponding to the highest and lowest signal from the filters. These two outputs are passed to a single comparator which produces an output when the difference between highest and lowest exceeds a threshold Fig. 2, (not shown).
