Title: Improvements in or relating to the production of glass and like mineral fibres
IPC: C03B37/005
Filed: 1961-12-18
Abstract: <PICT:0959906/C1/1> <PICT:0959906/C1/2> In the manufacture of glass and like mineral material, a stream of molten mineral material is introduced into a stream of gaseous medium and the suspension of fibres so obtained is contacted with a liquid in an amount exceeding 50% by weight of the fibres, whereby the fibres are prevented from twisting together and/or forming fibre balls. As shown in Fig. 1, a centrifuge 1 is mounted on a horizontal rotary hollow shaft 2 which communicates with the hollow interior 5 of the centrifuge for the passage of coolant such as water, the water being spread by a cover sheet 8.  Molten glass 13 is supplied to the rim 14 of the centrifuge 1 by an inclined shoot 12 and forms a ring 15 which is thrown out at the edge 16 into a stream of gaseous medium from openings 11 in an annular nozzle 9 supplied through a duct 10.  The cooling water in the interior 5 continues on through a pipe socket 7 in the rear wall 6 of the centrifuge and is flung outwardly to give a curtain of water into which the fibres and the gaseous suspension are introduced.  As shown in Fig. 4, the open pipe socket 7 is replaced by a tubular projection 20 having six nozzles 21 to give jets of water which combine into a curtain.  The projection 20 may be replaced by a screwed in closed tube with openings instead of the nozzles 21.  The liquid may be sufficient to form a suspension of the fibres, with the fibres in a concentration of less than 0.5% by weight, and may contain additives such as binders, drying oil emulsified therein or fibres or other solids in suspension.

Title: Improvements in Successive Approximation Analogue to Digital Converters
Inventor: WHEABLE DESMOND
IPC: H03M1/00
Filed: 1967-10-04
Abstract: 1,192,647. A/D converters. SOLARTRON ELECTRONIC GROUP Ltd. 3 Oct., 1968 [4 Oct., 1967], No. 45281/67. Heading G4H. In an analogue/digital converter of the type in which the unknown analogue voltage is applied to an integrating circuit 11, Cl (Fig. 1), the output of which ramps up from a datum level for a predetermined time interval and clock pulses discharge the integrator output to the datum level, the integrator is discharged by pulses of e.g. N<SP>3</SP> units until its output passes through the datum level (detected by detector 13) when pulses of - N<SP>2</SP> units are applied to restore it to the datum. A finer approximation is then achieved by applying pulses of N units. These pulses are counted by counter 17 which is connected to a display 19. When N = 10, if the number of pulses applied in each range is n 1 , n 2 , n 3  then n 1 -1, 10-n 2  and n 3 -1pulses are displayed by multi-cathode display tubes. The weighted pulses applied to the integrator circuit are derived from weighted resistors (R2, R3, R4) to which clock pulses are applied via gates (S3, S5, S6) controlled by logic circuitry (14) connected to the detector (13). The logic circuitry also enables a gate (S 4 ) to allow the clock pulses to be simultaneously accumulated in the counter (17). A reference voltage may alternately be connected to the resistor network, the ramp outputs from the integrator circuit being timed by clock pulses.

Abstract: 1323136 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Sept 1970 [26 Sept 1969] 45340/70 Heading H1K A N-type Si wafer 1, Fig. 3, carries an N-type epitaxial layer 2 overlain by a thermally oxidized Si layer 3. After grinding a Ni layer 4 is electroless plated on the remote side and heated to establish low ohmic contact. Square apertures are etched in oxide layer over photoresist and the surface is vapour-deposited with a Ni layer 6 lying partly on the oxide layer and partly on the exposed epitaxial Si to establish rectifying Schottky contacts. The structure is subjected in a water bath to high power high frequency acoustic vibrations removing the Ni layer overlying the oxide and leaving it adherent to the Si and a further nickel layer is applied to layer 4, Fig. 4. The wafer is scribed and broken into diodic portions enclosed in glass envelopes Fig. 5, and soldered to base 10 with layer 6 contacted by Mo whisker pressure contact 9. The wafer may be connected to a support during acoustic treatment which may be conducted otherwise than in water. In fabrication of a switching diode (Figs. 6-10, not shown), the Si exposed in the windows may be etched away by HF + HNO 3  to undercut the oxide layer, and Pt may be sputtered on to the surface to establish Schottky contacts with the epitaxial layer and heated in N + H to promote adhesion. The acoustic treatment removes the Pt and the protruding oxide edges to obtain separate Schottky contacts, and the several diodes are separated by scribing and breaking and fitted into envelopes. Au and Pd and Ti may be used for contacts and Ge or IIIb-Vb compounds for semi-conductor, while the insulant layer may be Si 3 N 4  or Al 2 O 3 . The method is applicable to non-rectifying semi-conductor contacts. Adherent metal strip connections of, e.g. Cr or SiO 2  applied to the insulant layer may replace whisker connections.

The starting cephalosporin, preferably as its amine, alkali metal or alkaline earth metal salt, is converted to the mixed acid anhydride by reaction with a compound of formula wherein each of R<SP>1</SP> and R<SP>2</SP>, which may be the same or different, is halogen, an alkyl, aryl, aralkyl, alkoxy, aryloxy or aralkyloxy group which groups may be substituted, or R<SP>1</SP>, R<SP>2</SP> and M<SP>1</SP> may together form a ring, M<SP>1</SP> is boron, aluminium or phosphorus and X is a halogen atom; R<SP>3</SP>, R<SP>4</SP> and R<SP>5</SP> are each substituted or unsubstituted alkyl, aryl, aralkyl, alkoxy, aryloxy or aralkyloxy group, or each of R<SP>4</SP> and R<SP>5</SP> may be a halogen atom, or R<SP>4</SP> and R<SP>5</SP> taken together represent O, S or O 2 , or R<SP>4</SP>, R<SP>5</SP> and M<SP>2</SP> may together form a ring, M<SP>2</SP> is a carbon or sulphur atom and X is halogen; and each of R<SP>9</SP>, R<SP>10</SP>, R<SP>11</SP> and R<SP>12</SP> is a halogen atom or an alkyl, aryl, aralkyl, alkoxy, aryloxy or aralkyloxy group which groups may be substituted, or R<SP>9</SP> and R<SP>10</SP> taken together represent O, or R<SP>11</SP>, R<SP>12</SP> and M<SP>4</SP> may together form a ring, M<SP>4</SP> is a phosphorus atom and X is halogen. The reaction is preferably effected in an insert solvent in the presence of an acid-binding agent. The resulting solution of mixed acid anhydride is then treated with the imide halide-forming reagent, e.g. POCl 2 , PCl 5 , PBr 3 , PBr 5 , COCl 2 , SOCl 2 , oxalyl chloride, protocatechinylphosphorus trichloride or toluenesulphonyl chloride. The imide halide produced is then converted to the corresponding imino ether by reaction with the aforesaid hydroxyl compound R.OH (e.g. methyl, ethyl, propyl, butyl, amyl or benzyl alcohol, ethylene glycol, ethylene chlorohydrin, #-cyanoethanol, 2-ethylhexanol, cyclohexanol, or ethyleneglycol monomethyl or monoethyl ether). The imino ether is subsequently hydrolyzed by treatment with ice water, which effects simultaneous hydrolysis of the imino ether moiety to -NH 2  and of the mixed acid anhydride group to -COOH, resulting in the desired 7-aminocephalosporanic acid. The latter may be isolated from the hydrolysis mixture by addition of a basic substance to bring the pH to the isoelectric point of the product so that it crystallizes out from the solution.
