Title: Improvements in or relating to the formation of connections on microelectronic circuits
Inventor: DAVEY NORMAN
IPC: H01L21/48
Filed: 1968-03-28
Abstract: 1,260,468. Welding by pressure. NATIONAL RESEARCH DEVELOPMENT CORP. 26 March, 1969 [28 March, 1968], No. 15028/68. Heading B3R. [Also in Divisions C1, H1 and H2] In forming connections to metallic conductors of a microelectronic circuit pattern on a substrate, an apertured mask is located over the pattern, metallic particles thicker than the mask are placed in apertures in the mask in contact with the conductors, the particles are pressed against the conductors to bond them thereto and the mask is removed to leave connection pillars bonded to the pattern. A substrate 1 of alumina has a pattern of conductors 2 formed thereon by screen printing or by vacuum deposition through a photo-resist mask, the conductors being at least surfaced with gold, and over the pattern a perforated mask 4 is held, gold spheres 8 being brushed over the mask to occupy the perforations. The spheres protrude above the mask which may be of foil not containing lead, e.g. aluminium or phosphor-bronze or plastics sheet and large perforations may be filled with several spheres side by side. With the substrate on a platen 6 a movable steel platen 7 is pressed on to the spheres to deform them to fill the perforations and pressure bond them to the conductors. The platens 6, 7 are preferably heated and the substrate may be heated to 150-250‹ C. The mask is peeled away leaving upstanding pillars on which inverted integrated circuit chips may be thermocompression bonded. An insulating layer may be formed on the substrate about the pillars before the chip bonding to protect the conductors by applying a colloidal suspension of powdered glass frit in a volatile liquid, e.g. isopropyl alcohol in ethyl acetate and heating to fuse the glass. Instead of mounting chips on the pillars which extend above the insulating layer, the pillars are ground to be flush with the layer and a further pattern of conductors is formed thereon. The process may be repeated to form a multilayer microelectronic circuit with interconnecting pillars. Instead of a glaze an epoxy resin insulating layer may be used possibly containing alumina particles or in a multilayer circuit a series of glazes of progressively lower fusion temperatures or a glaze containing refractory oxide particles may be used.

Patent GB-1320071-A (GB)
Title: Rotary vibrator
IPC: B06B1/16
Filed: 1971-05-17
Abstract: 1320071 Mounting rotors for dynamoelectric machines P U POULSEN 17 May 1971 [19 May 1970] 15370/71 Heading H2A [Also in Division F2] A rotary vibrator, comprising an electromotor connected to the object to be vibrated so that the vibrations of the rotor of the motor are transmitted to the object through the base of the vibrator via bearings for the rotor and the stator of the motor, has at least one end of the motor shaft journalled in a roller or ball vibration bearing of a type adapted to impart to the shaft a translatory movement of a frequency which is a multiple of the rate of revolution of the motor shaft. A vibration bearing of this type is described in Specification 1,295,847 and is illustrated diagrammatically in Fig. 2 (not shown). The vibrator illustrated in Fig. 3 has a stator 21, a rotor 22 and a shaft 13 journalled at both ends in vibration bearings 14 with the central member attached to the shaft 13 and the ring member 17 secured to the stator 21. Where stronger vibration than provided by shaft and armature is desired, additional masses (e.g. masses 12) may be placed on the shaft ends concentrically with respect to the shaft. By positioning the additional masses eccentrically, however, it is possible to obtain a lower frequency vibration superimposed on the vibration caused by the vibration bearings. The eccentricity of these masses may be adjustable. A greater clearance than normal must be provided between the armature and stator of the motor, and on account of the eccentricity of the translatory movement the distance between the two parts will always be greater at one side of the armature than at the other. This drawback can be overcome by using a motor in which the armature and stator are placed end to end. Only one vibration bearing may be used instead of two (Fig. 1, not shown) and the other end of the shaft is then journalled in an ordinary bearing which, however, must be able to permit a certain angular movement. In this case the rotor axis moves around a conical surface about the stator axis and only half the mass of the rotor can be calculated as rotating mass. Additional mass may be provided close to the vibration bearing and, as described above, may be formed concentrically or eccentrically according to the desired vibration.
Patent GB-789132-A (GB)
Title: Improvements in or relating to resistance welding
IPC: B23K11/24
Filed: 1955-05-27
Abstract: 789,132. Electricity supply systems for resistance welders. FORD MOTOR CO., Ltd. May 27, 1955, No. 15407/55. Class 38 (4). Relates to a resistance welding system in which a series of welds are made by first closing the electrodes to apply pressure to the work, compressed-air controlled by a solenoid valve being used for this purpose. The welding circuit is then energized to start the actual welding period, after which the welding current is discontinued while the pressure of the electrodes against the work is maintained for an interval. Closure of timer-controlled contacts 31 energizes the solenoid valve 30 and relay 17 which closes contacts 16 and opens contacts 20, whereby the primary windings of transformer 15 and of welding transformer 12 are connected in series across supply lines 10, 11. As long as the secondary circuit of the welding transformer is open, the secondary voltage of the transformer 15 is such that a thyratron 26 remains non-conducting. When a firm contact is established between the welding electrodes through the work, however, the valve is caused to strike so that relay 23 opens contacts 22 and closes contacts 34. The latter contacts are employed to control the firing of ignitrons 13 which are connected in parallel with the primary winding of the transformer 15 and are used to energize the welding transformer. An indicating lamp 21 is connected in series with contacts 22 across the primary winding of the welding transformer, and this lamp is lighted only when the primary winding is energized prior to its secondary being solidly shortcircuited through the electrodes and work. A further indicating lamp 18 is lighted when the welding transformer is energized and the solenoid 30 is de-energized, contacts 20 being closed. Actuation of a double-throw switch 33 enables the welding transformer and associated cables to be checked for short-circuits. If such short-circuiting exists, the thyratron 26 actuates relay 23 and the pilot lamp 21 does not light. The transformer 15 may be replaced by a potentiometer or tapped reactance, Figs. 2, 3 (not shown). In another arrangement, the transformer is replaced by a voltagesensitive relay which is adapted to close at full line-potential, but not at full line-potential minus the reactive voltage-drop of the welding transformer with the secondary winding opencircuited. Contacts of this relay may be substituted for the contacts 34. A timer may be introduced into the control circuit for delaying the firing of the ignitrons for a short period after the secondary winding of the welding transformer has been short-circuited. The discharge of the thyratron 26 may be used to initiate the welding cycle through means other than the relay 23.

Title: Improvements relating to vapour generating and superheating units and to the control of the temperature of superheated vapour
IPC: F22G5/04
Filed: 1953-06-04
Abstract: 738,214. Steam superheaters, BABCOCK & WILCOX, Ltd. June 4, 1953 [June 4, 1952], No. 15417/53. Class 123 (3). A steam boiler comprises a furnace chamber 10 divided into two vertical compartments by a mid-partition formed of steam generating tubes, the front and side walls of the chamber being lined with generating tubes whilst the rear or baffle wall 24, which is also formed of generating tubes, serves to separate the furnace from an uppass 32 in which is disposed primary and secondary convection superheaters 90, 96 and an economizer 156. Each furnace compartment is downwardly fired by a group of pulverized fuel burners 100, the burner groups, which are enclosed in windboxes 104, 105, being spaced inwardly from the compartment walls, so that in operation, combustion gases pass down through each compartment without impinging on the walls thereof, the gases then turning laterally for upward flow through pass 32. The steam generating tubes extend between headers such as 20, 38 and a steam and water drum 26 from which steam flows through the primary superheater 90, an interstage attemperator 93 and the secondary superheater 96 to the final outlet header 98. To maintain the temperature of superheat constant over a wide load range, the attemperator 93 is used at high loadings when the superheat temperature tends to rise above the required value, whilst at low loadings when the steam temperature tends to fall, flue gas is recirculated to the furnace to reduce the radiant heat absorption therein and give a corresponding increase in the heat content of the gases entering the superheater pass 32. The flue gas is withdrawn from outlet duct 155 by a fan 150 which discharges it through ducts 140, 142, 144 and damper controlled vertical ducts such as 120, 125 into manifolds 110 ... 113 and 114 ... 117 surrounding respectively the windboxes 104, 105, the gas passing through slots 118 provided along the undersides of the manifolds to form a downwardly moving layer on each wall surface of the furnace compartments thus partly screening the lining tubes thereof from transfer of radiant heat from the combustion products passing from the burners centrally down each compartment. By operation of the dampers in the vertical ducts such as 120, 125, the flue gas layer can be formed on one or more selected surfaces whilst the flow velocity of the layer can be controlled by adjustment of the fan speed. To avoid premature mixing of the flue gas and fresh combustion gas, the flow velocity of the flue gas layer is made approximately the same as or greater than that of the stream of combustion gas. The attemperation and gas recirculation may be automatically controlled by apparatus such as that described in Specification 729,437. Specifications 367,699, 504,114, 516,070, 523,870, 540,119 and 721,155 also are referred to.

Patent GB-626516-A (GB)
Title: A process for preparing halogen-substituted unsaturated organic nitriles
Filed: 1947-06-12
Abstract: Unsaturated halogen-substituted nitriles are prepared by reacting an unsaturated organic nitrile, containing at least four carbon atoms in the molecule and having a double bond between two carbon atoms at least one of which is adjacent to a carbon having a substitutable hydrogen attached thereto, with a halogen at an elevated temperature at which mainly halogen substitution occurs but below a temperature which promotes substantial degradation. The double bond is preferably conjugate to the carbon-nitrogen bond of the nitrile group.  The following compounds are specified: crotononitrile, 2-pentenenitrile, methacrylonitrile, a  - ethylacrylonitrile, 2 : 3 - dimethyl - 2-butenenitrile, and 5 - methyl - 2 - hexenenitrile.  Examples of compounds with the double bond not conjugated in this way are vinylacetonitrile and 3 - methyl - 3 - pentenenitrile.  Other suitable compounds are cyclic olefins such as 2-cyclohexene-1-carbonitrile, and diolefins such as 2 : 5-hexadienenitrile and 1 : 3-cyclohexadiene-1-carbonitrile.  All may contain inert substituents such as aromatic, naphthenic, or halogen groups.  The preferred class of starting material is <FORM:0626516/IV (b)/1> where R is hydrogen or alkyl, i.e. methacrylonitrile and its homologues.  The range of the reaction temperature is about 250-600 DEG  C., preferably within about 350-550 DEG  C., and the reaction may be performed in the liquid or vapour phase, and at ordinary or reduced pressures.  In a vapour phase reaction the reactants may be streamed through a tube which may be metal, e.g. monel or steel, or other material, e.g. carbon or glass.  It is preferred in some cases to preheat the nitrile prior to reaction with the halogen, and it is desirable to quench rapidly after the reaction.  Unreacted starting material may be recycled in a continuous process.  If necessary, the reactor may be cooled, an inert diluent gas may be used, or the gases may be streamed through the reaction tube at a velocity greater than that of flame propagation.  Either the halogen or the nitrile may be used in excess, but preferably a halogen to nitrile ratio of 1 : 1 to 1 : 5 is employed.  In examples: (1) and (2), methacrylonitrile is chlorinated to give 2-(chloromethyl)-acrylonitrile, in (4) it is brominated to give the bromomethyl compound, in (3) crotononitrile is chlorinated to give g -chlorocrotononitrile, and in (5) a  : b -dimethyl-acrylonitrile is chlorinated.  The unsaturated nitriles may be prepared by reaction of unsaturated acids with ammonia at an elevated temperature in the presence of alumina or other catalyst.
