Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1929-09-05
Abstract: 339,600. Automatic Telephone Manufacturing Co., Ltd., and Gillings, C. Sept. 5, 1929. Divided on 339,345. Drawings to Specification. Automatic exchange metering systems.-A discriminating selector at a satellite exchange, in response to one or more digits transmitted from a sub-satellite, determines' whether the connection is to be completed over the selector wipers or over a junction to the main exchange and at the end of the conversation controls the selection of one of a series of metering cams whereby the appropriate number of metering impulses is transmitted back to the sub-satellite. The selector may drop back after the first digit and respond again to the second, the selection of the appropriate metering cam being determined by the position which the selector occupies during conversation. The invention is described with reference to a system identical with that described in Specification 339,345.

Title: Improvements in or relating to recovery of ammonia in urea synthesis
IPC: C01C1/10
Filed: 1953-11-20
Abstract: A urea synthesis melt comprising urea, ammonium carbamate, water and ammonia is heated, e.g. by steam coils, in a pressurized still at a sufficient temperature to evolve ammonia and carbondioxide which are passed upwardly into a liquid-vapour contact zone, e.g. a packed tower; a flow of said melt is passed into said zone at an intermediate level and flows downward in countercurrent contact with the rising vapours whereby additional ammonia and carbon dioxide are evolved; a reflux flow of liquid ammonia is introduced into the upper levels of said zone at a rate sufficient to redissolve substantially all carbon dioxide evolved in said zone but sufficiently low that more ammonia gas than corresponds to the liquid ammonia input passes out of said zone; the carbon dioxide-free ammonia is removed from the top of the zone, residual liquor is removed from the still, the rates of melt input and liquor removal being constant, and the temperature and pressure are maintained substantially constant at values such that the removed liquor has the desired constant solute content.  The pressure may vary from 100 to 400 p.s.i., preferably 157-228 p.s.i. The amount of ammonia introduced may vary from 50-150 per cent by weight, preferably 70 per cent, of the ammonia content of the urea synthesis melt.  The reflux temperature of the added ammonia varies with pressure.  Typical urea-synthesis melts have the composition: urea 25-35 per cent; ammonium carbamate 8-15 per cent; water 5-15 per cent; and free ammonia 30-50 per cent, by weight.  A detailed example is given.

Abstract: 342,269. Decorating sheet material ; lampshades &c. BROWN, J. E., 197, Preston Drove, and COOPER, E. C. H., 10, Regency Mews, both in Brighton. Oct. 28, 1929. No. 32619 [Class 93.]. A decorative effect is produced on transparent or translucent sheet material suitable for the manufacture of lamp-shades and similar articles by applying a thick coating of slow-drying varnish, and subjecting the coated surface to a high temperature for a short time to produce a wrinkled surface and then to a lower temperature for a longer period to dry and harden the coating. The material used may be paper, parchment, that sold under the registered Trade Mark "Cellophane," fabrics, or glass, and may be decorated either before or after the material is made up into the article. The varnish is applied to one or both sides by means of a brush, by spraying, or by dipping, the material is placed for from 5 to 10 minutes in an oven at a temperature of 300‹ F., and is then transferred to an oven at a temperature of 140‹ F., this temperature being maintained for eight hours. The articles may be coloured, or colour may be mixed with the varnish. Where "Cellophane" or other hygroscopic material is used, the material is dried out before applying the varnish.

Title: Improvements in or relating to electric amplifier arrangements
IPC: H03H7/48
Filed: 1955-11-17
Abstract: 807,677. R.F. couplings. GENERAL ELECTRIC CO. Ltd., and GRIFFITH, G. W. S. Nov. 14, 1956 [Nov. 17, 1955], No. 32961/55. Class 40 (7). An amplifier arrangement is designed so that if a proportion of its output is reflected back due to mismatch (for example from an aerial) the signal is not again returned to the output in the form of a delayed echo. According to the invention the arrangement comprises a first hybrid ring 3 fed with incoming energy at 9 and having equiphase outputs at 10 and 7 to which are coupled amplifiers 1 and 2 by lines 15 and 17 differing by an odd number of quarter wavelengths. The amplifier. outputs are respectively coupled to points 13 and 12 on a second hybrid ring 4 by lines 16 and 18 which also differ by an odd number of quarter wavelengths such that the ring 4 combines the two signals in phase at 14 and feeds them over line 21 to aerial 22. Point 11 on ring 4 is coupled to point 8 on ring 3 by a feedback path 23 which may include adjustable phase shifting and/or attenuating networks. If, due to mismatch, signals are returned from the aerial 22 to ring 4 these are divided equally between lines 16 and 18. Provided the amount reflected by amplifiers 1 and 2 is the same the signals returning to the ring 4, being in antiphase, have no effect at point 14 but add at point 11. This output is fed back to ring 3 over line 23 where it is applied to the amplifier channels in antiphase. The outputs at ring 4 due to it once more have no effect at point 14 and the phase shift and attenuation in line 23 is chosen so that it acts as a degenerative feedback loop to reduce the echo signal level. The hybrid devices may be rings of waveguide or coaxial transmission line or they may be waveguide hybrid T junctions. Specification 735,927 is referred to.
