Abstract: 1,076,440. Semi-conductor devices. MOTOROLA Inc. June 16, 1966 [June 28, 1965 (2)]. No. 26999/66. Heading H1K. A common substrate 11 supports a plurality of semi-conductor devices 13, 14, 15, 16 formed in discrete monocrystalline semi-conductor islands which are isolated from each other and from the substrate 11 by a continuous layer 12 of glass. The glass is intimately bonded both to the semi-conductor islands and to the substrate, and all three have similar thermal expansion characteristics. The semi-conductor devices are connected into a circuit by means of metallic conductors 22, 23, 24, 25, 26 passing over an oxide layer 21. In manufacture, channels are etched in one face of a monocrystalline semi-conductor wafer, a layer of glass is formed on the etched face, the substrate 11 (which may be of the same semi-conductor material) is bonded to the glass-coated face of the wafer, and the opposite face of the wafer is removed to a depth sufficient to expose portions of the glass layer, leaving islands of semiconductor material surrounded by glass. The formation of the glass layer may involve the application of finely-divided glass in a volatile diluent to both the wafer and the substrate, or the application to the wafer of a material which forms a glass on oxidation and to the substrate of a metal capable of being oxidized to a glass. A film of silicon dioxide may be formed first on both the wafer and the substrate. Other circuit components may be deposited on the surface of the glass between the semiconductor devices.

Patent GB-809767-A (GB)
Title: Recovery of terephthalic acid
IPC: C07C51/41
Filed: 1957-08-30
Abstract: The invention comprises a process for the recovery of terephthalic acid from aqueous solutions of dialkali metal terephthalates by mixing the said solutions with benzoic acid in an amount at least equal to 1.9 mols. per mol. of the terephthalate, separating the solids from this reaction mixture slurrying said solids in water, and then separating the solids from this second reaction mixture.  The slurrying process may be repeated one or more times and the solids may be separated in either case by e.g. filtration or centrifugation. The initial solution of dialkali metal terephthalate preferably contains about 1-15 per cent of dialkali metal terephthalate, but may be saturated.  The amount of benzoic acid present should be at least equal to about 1.9 mols. per mol. of dialkali terephthalate and preferably does not exceed about 2.5 mols. per mol. of dialkali terephthalate.  Suitable reaction temperatures are from approximately the freezing point of water up to the critical temperature of the water.  It is preferable to use temperatures about 100 DEG  C., and in the case of temperatures above the boiling point of the reaction mixture, superatmospheric pressure is required.  The solids should be separated from the reaction mixture at relatively low temperatures, preferably no higher than about 60 DEG  C., and the rate of cooling of the reaction mixture is preferably controlled to give maximum particle size.  The separated solids may be washed lightly to remove occluded mother liquor which contains the alkali metal benzoate.  The slurrying process is preferably carried out using from about 2-20 times as much water as the dry weight of the solids present.  The alkali metal benzoate remaining at the end of the separation may be recovered and recycled for the manufacture of more dialkali metal terephthalate.  Alkali metals mentioned are potassium, sodium, lithium, and rubidium.  Examples are given.  Specifications 744,721 and 747,204 are referred to.

Filed: 1963-07-10
Abstract: 966,365. Two-part couplings. AMP Inc. July 10, 1963 [July 16, 1962], No. 27358/63. Heading H2E. An electrical connector (Fig. 1) has a pin portion 5 formed by rolling up a sheet metal blank such that the edge portions 6 of the blank are rolled up inside the pin portion (Fig. 3). The connector is formed with a serrated ferruleforming portion 1 which may be crimped to the bared end of an insulated lead. A metal sleeve 3 and an encasing insulating sleeve 4 are arranged to be crimped to the insulation of the lead and to cover the ferrule portion 1. The pin is formed as a pair of parallel open tubes 8 joined by a convex base portion 9, for engaging a receptacle for the pin. The outsides of the tubes 8 touch and together form a relatively flat contact surface opposite the curved base 9. The pin may be inserted into an aperture in a metal connector block and clamped in position by a screw, driven through a tapped aperture in the block, perpendicular to the pin, to engage the contact surface provided by the tubes 8. Tightening of the screw resiliently deforms the pin by bending the edge portions 6 inwards. The resulting outward elastic force urges the screw into tighter engagement with the aperture screw-thread, thus preventing loosening of the screw due to vibration. Specification 924,819 is referred to.
