Abstract: 975,962. Aerials. CSF-COMPAGNIE GENEBALE DE TELEGRAPHIE SANS FIL. Dec. 11, 1961 [Dec. 15, 1960], No. 44298/61. Heading H4A. In an aircraft an aerial radome (not shown) is combined through a conical coupling member 1 with a conical anemometer tube 5 and if the latter is made wholly or in part of dielectric material it tends to act as a directive secondary radiator. This disadvantage is overcome according to the invention by partially coating or covering the dielectric portion of the anemometer tube with a metallic layer. The extent of this layer is empirical and when as in the embodiment shown the whole tube is formed of dielectric material, the metallic layer may extend between the sections 3 and 4. The effect of this on the transmission factor and on the refraction error of a paraboloid aerial fed from a four channel " monopulse " source is illustrated (Figs. 2 and 3, not shown). In a further embodiment (Fig. 4, not shown), which comprises a tube having a metallic and a dielectric portion, a metallic coating is applied to a part of the dielectric portion to give two metallic parts separated by a dielectric part. The radome is made from laminated polyester glass. The metallic coating for the anemometer tube may be a brushed on layer of colloidal silver or it may simply be a metallic sleeve.

Title: Apparatus for sending information from one location to another
IPC: G11C11/44
Filed: 1960-12-29
Abstract: 920,370. Electric selective-signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 29, 1960 [Dec. 30, 1959], No. 44560/60. Class 40 (1). Data is transmitted over a plurality of channels each of which is assigned a different priority rating; and when a fault is detected on two or more of the channels simultaneously, one of a number of spare channels is switched in to replace that faulty channel which has the highest priority. In the embodiment described the information channels extend between cryogenic elements printed on plates immersed in a liquefied gas, for example in a computer. Information to be transmitted over channels M1-M4 is set into cryogenic bi-stable circuits of sending register 10, and, in normal operation, current flows in either the ONE or ZERO line of each channel M1-M4, through replacement switches 12, 14 to set corresponding bi-stable circuits in receiving register 16. If a break occurs in one channel line carrying current, no current will flow along a corresponding one of lines 20-23, it being diverted along one of lines 31-34 to the replacement switch control circuit 70 in which it co-operates with current flowing in one of the output leads 61-65 of shift register 56 to drive a cryotron gate resistive and provide a superconducting path from the defective channel output of the sending register 10 to one of the spare channels S1-S5 determined by which of leads 61-65 is marked. At the same time, the absence of current on the corresponding lead 80-83 causes a corresponding switching operation to take place at the receiving end so that the spare channel is connected to the defective channel input of the receiving register 16. Shift register control circuits then cause shift registers 56, 110 to mark their next output lead in preparation for selecting the next spare channel, a reset pulse on lead 38 restoring current to the " repaired " channel. If several channels develop faults simultaneously, the detector and sequence circuits 30, 90 allot the available spare channels in sequence in a predetermined order of preference. For example, if channels M1, M3, M4 develop faults and spare channel S1 is already in use, then channel S2 may first replace M4, then channel S3 may replace M3, and finally S4 may replace M1. Specification 862,178 is referred to.

Title: Improvements in or relating to the production of glass sheets
IPC: C03B19/00
Filed: 1964-11-09
Abstract: A process for the production of flat glass sheets of predetermined dimensions and shape, having fire-polished and very flat surfaces and rounded and polished edges, comprises the steps of (a) introducing on to the horizontal flat bottom of a heated mould made of a material not wetted by glass a volume of molten glass not less than that which upon freely flowing will just cover the whole surface of the mould bottom without contact with the sides of the mould, (b) allowing the molten glass in the mould to spread out under the combined action of gravity and surface tension to produce a layer of uniform thickness, the rounded edges of which are in contact with the inner surface of the mould side walls, said side walls being made of a material which is not wetted by glass, (c) quickly cooling the glass layer to form a sheet, (d) maintaining the glass sheet in a "plastic" condition on the surface of a molten metal bath for a time long enough to eliminate surface and/or flatness defects from its faces, and (e) gradually cooling and then annealing the sheet.  A measured quantity of glass from a graphite lined ladle 18 is poured into a heated graphite mould 1, 5 in a compartment 7 of a furnace.  The glass reaches its equilibrium thickness in the mould, which is then transferred by a trolley 14 upon which it is mounted into a compartment 8.  Here a water-cooled box 19 is lowered on to the mould to quickly chill the glass sheet 3.  The trolley is moved up a stage where the mould side walls 5 are removed and the trolley tilted so the cooled "plastic" sheet 3 can slide off on to an inclined graphite surface 21 from whence it slides on to the surface of a molten metal bath, e.g. molten tin.  Here the sheet is polished and has any <PICT:1060128/C1/1> <PICT:1060128/C1/2> surface blemishes removed before being gradually cooled so that it may be removed unharmed to an annealing lehr.  Radiant heaters 16 in compartment 7 heat the mould, and there are radiant heaters 23 above and heaters 24 in the molten metal bath.  A protective non-oxidizing atmosphere of nitrogen or hydrogen and nitrogen is supplied through ports 26. In an alternative embodiment the molten metal bath also forms the mould bottom and in this case a measured quantity of glass is delivered from a graphite lined shoot 33 into a mould formed by a graphite frame 29 supported upon the molten metal bath.  A string of frames attached by graphite bars 30 are slowly advanced along the bath so that a semi-continuous production line is set up.  When the glass is sufficiently cool it and the mould frame is removed through a port 44 into an annealing lehr, the frame being returned to the front end of the furnace.  A protective atmosphere is maintained above the molten metal bath. It is possible to have a plurality of lines of moulds on one bath continuously fed from one or more feeder channels.
