Abstract: 1504097 Printed circuits HONEYWELL INFORMATION SYSTEMS Inc 23 March 1976 [26 March 1975] 11589/76 Heading H1R A multi-layer electronic circuit package 14 (Fig. 1) comprises plural integrated circuit semiconductor devices 10 mounted on its upper surface 12. The input and output of each circuit are each connected to pads 16 of the surface over leads 18; the pads being spaces round each semi-conductor device by incremental S or integral multiples thereof (Fig. 2) in a grid pattern 19. Underlying planes 20, 22 carry sets of equally spaced parallel lines respectively orthogonal one to the other, the spacing W being S/2 and defining a W spaced grid work positioned so that each intersection underlies a corresponding pad, as shown, e.g., by projections 24, 30, 32, 34, 36 which also intersect every other line on one of the conductive planes. Interpolated lines, e.g. 40, 46, define unconnected circuit paths underlying the semi-conductor devices which enable other circuits to be defined, and are interconnected by, e.g., lines 48. In manufacture an alumina substrate 60 (Fig. 3) is formed with W-spaced conductive lines 62 by silk screening a gold and silicate glass frit in an organic binder over a photosensitive mask and firing. A dielectric layer 64 is superimposed by silk screening a dielectric paste over a photosensitive mask to leave via holes 66 spaced by W and overlying the lines 62. The layer is dried at high temperature and a further layer is deposited over the same mask; after which the via holes are filled with gold to interconnect with lines 62 at 70. A further series of spaced conductive lines 72 is applied in plane 20 at right-angles to lines 62 and contact certain of the interlayer conductors 70 for electrical connection. A further dielectric layer 74 is then deposited over a mask in similar manner to the first, and the spaced via holes 76 are filled with gold as before to form interconnections 78, over which pads 16 are correspondingly deposited in plane 12 extending to the conductive lines 62, 72 of planes 20, 22. Base mounts 82 are formed on plane 12; the formation being by silk screening with gold glass frit paste, drying depositing solder thereon, and heating to establish connection with respective semi-conductor pads 10 and leads 18 placed in contact therewith. Other circuitry may be similarly placed on plane 12 and interconnected over conduits 66, 75 to lines 62, 70 while further dielectric may be superimposed on plane 12 with appropriate via hole contacts for further circuitry carried thereon.

Title: Improvements in the conversion of hydrocarbons of high boiling point into others of lower boiling point
Filed: 1927-05-02
Abstract: 270,704. I. G. Farbenindustrie Akt.- Ges. May 7, 1926, [Convention date]. Void [Published under Scct. 91 of the Acts]. Hydrocarbons, cracking; hydrogenation, destructive.-Hydrocarbons of high boiling point are converted into others of lower boiling point by passage through a heated column packed with catalytic materials, the inner surface of the column being lined with materials which do not give rise to deposition of carbon. Suitable materials for lining the column are metals other than those containing face iron, e.g. aluminium, copper, special steels or quartz or porcelain. The catalysts used may include metals, metalloids, oxides, salts &c. The process is carried out under such conditions of temperature, rate of flow &c. that only the products distilling below the boiling points desired are allowed to distil over. e.g. by providing the column with a reflux condenser. Preheated crude mineral oil is allowed to trickle slowly down a heated silica column containing as catalyst copper " permutite," the temperature of the column being 500‹ C. at the bottom and 300- 350‹ C. at the top. A current of gas e.g. nitrogen, hydrogen or steam with or without air may be passed up the column.

Filed: 1930-04-12
Abstract: 347,465. Shoots. MITCHELL, F. G., Albyns, near Romford, Essex. April 12, 1930, No. 11683. [Class 78 (i).] Discharge apertures at the lower end of a shoot for delivering coal into vessels, &c. are controlled by doors which are held closed when the shoot is empty and are opened automatically when coal fed into the shoot has reached a predetermined height therein. The doors 2, 2a are hinged to the lowest section 1d of the shoot and are connected by links 3, 3a to the free ends of arms 4, 4a which are pivoted to the shoot at 4b, 4c. When the links and arms are in alignment, the doors are closed and cannot be opened. The alignment of the parts is broken by the upward movement of the core 5a of a solenoid 5 which occurs when the solenoid is energized by the closing of a switch 20 mounted on the top section 1a of the shoot. The switch is connected by a link 22a to an arm 22 carried by a flap door 21 normally kept closed by a weight 22b, but opened by the pressure of the coal against it when the shoot is full. The sections 1a . 1d, are connected so that they can be moved telescopically by a rope 12 which passes round guide pulleys 12a, 12b and is wound on a drum 11.

Title: Improvements in or relating to electromagnetic induction apparatus
IPC: H01F27/245
Filed: 1953-04-28
Abstract: 725,372. Transformers and inductors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 28, 1953 [May 17, 1952], No. 11698/53. Class 38 (2). A laminated core structure 84 is characterized in that in addition to the normal insulating material 87 between the laminations 85 there is provided between the laminations extra insulation in the shape of the members 92, 94 which divide the structure into three parts 86, 88, 90, which sections are earthed as shown at 96, 98, 100. Thus when a voltage impulse is applied to the windings associated with the core structure, electrostatic voltage gradients are produced across the core sections which may be sufficient to break down the normal insulation 87 between the laminations 85. However, due to the core structure being divided into three sections the electromagnetic voltages induced in the core sections 86, 88, 90 by the windings are not so great as to increase the core losses unduly. Any number of extra insulating members may be used and the core sections may be earthed at the end lamination instead of at the centre one.
