Patent GB-1017850-A (GB)
Title: Intermittently operable fluid jets
IPC: D21F1/32
Filed: 1964-06-04
Abstract: Apparatus in which a multiplicity of spaced fluid jets can be initiated extremely rapidly when required, e.g. to remove a broken paper web from the return run of the wire of a paper making machine, comprises a fluid supply pipe connected to a multiplicity of nozzles each normally sealed by sealing means which are connected to a pressurized fluid-containing manifold, means being provided to release the pressure in the manifold rapidly when desired thereby unsealing the nozzles and causing fluid jets to be established.  A pipe 12 carries a multiplicity of spaced nozzles 11 and is divided by an internal partition 14 into a pressure fluid supply passage 20 and a pressurized manifold 28.  Pressure in the two parts of pipe 12 may be maintained independently or small holes 41 may be provided allowing fluid to leak from passage 20 into the manifold 28.  The latter is connected to a solenoid-operated quick-acting valve adapted to release the pressure from the manifold 28 when desired, the release of pressure causing valve members 48, Fig. 2 (not shown), associated with each nozzle 11 to move to a nozzle-open position (shown dotted).  In this position fluid from the passage 20 flows via holes 44 to orifices 56 and strikes jet deflector plates 58 thus establishing a series of spaced fluid jets.  Photo-electric sensing means are employed to detect the breakage of the paper web in a paper making machine, Figs. 3 and 5 (not shown), and through a suitable electric relay control the opening of the solenoid-operated pressure release valve and thereby control the initiation of the jets of fluid.  In a modified form of the spray nozzle, Fig. 6 (not shown), a flexible diaphragm is used to make a seal between the valve member of each nozzle and the walls of the tubular member in which the valve member is arranged to move.

Title: Process for the manufacture of orthophosphoric acid
IPC: C01B25/22
Filed: 1959-07-08
Abstract: Ortho-phosphoric acid is produced by the opening up of raw phosphate with a stoichiometric amount of sulphuric acid, wherein coarse grained raw phosphate of size up to <PICT:0914815/III/1> 30 mm. diameter and not more than 10% smaller than 0.5 mm. diameter is continuously pasted with sulphuric acid in a conveyer vessel and the mixture is subsequently ground to complete the reaction in a grinder. Raw phosphate and sulphuric acid p  continuously enter screw conveyer 4 from silo 1 through weighing device 2 and conveyer 3 and from container 5 respectively. Conveyer 4 is closed and provided with ventilator port 8 leading to a washing and absorption system for the volatile reaction products, e.g. CO2 and HF.  The reacting mixture in conveyer 4 passes through outlet 9 into a rod mill 7 where reaction is completed.  Calcium sulphate-phosphoric acid reaction slurry continuously passes through outlet 10 through a series of ripening containers 11 and 12 which, by undisturbed standing of the slurry, preferably at 40 DEG -50 DEG C., promote crystal growth of the calcium sulphate to yield an easily filterable product. Phosphoric acid is finally isolated by filter 13 and passes off through pipe 16. Residual calcium sulphate sludge is successively washed with water 18 to produce dilute phosphoric acid, which is removed at 14 and recirculated through pipe 15 for addition to the sulphuric acid as dilution acid.

Title: Impurity regions in semiconductors

Filed: 1972-05-19
Abstract: 1397338 Manufacturing semi-conductors WESTERN ELECTRIC CO Inc 19 May 1972 [24 May 1971] 23584/72 Heading H1K A buried impurity region is formed in a semiconductor substrate by implanting ions of the impurity therein by bombardment, heating the substrate to diffuse the impurity ions further into the substrate and then removing surface substrate material damaged by the ion implantation, and growing an epitaxial layer on the substrate surface. The damaged surface material may be oxidized prior to its removal. The depth of the implanted region is from 300-3000 Š, preferably with an average depth of 1000 Š, which is sufficient to diffuse ahead of a growing oxide film. Simultaneously with the heating at 1200‹ C. in dry O 2  for 3¢ hrs. to diffuse in As implanted impurities into a Si substrate, a layer of SiO 2  is grown at the surface, which is subsequently removed by hydrofluoric acid. Residual disorder in the substrate after stripping the oxide is removed by etching an additional 5000 Š of substrate in the usual HF vapour etch cleaning process prior to epitaxial growth thereon. Alternatively the whole of the damaged region can be converted to oxide by heating at 1200‹ C. for 1 hour in dry O 2  to give a 2000 Š thick oxide layer and then heating at 1200‹ C. for 1 hour in steam to grow another 8000 Š of oxide. After removing the oxide an epitaxial N-type region is formed thereover to give a final transistor structure.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1925-09-23
Abstract: 263,226. Automatic Telephone Manufacturing Co., Ltd., (Automatic Electric Co.). Sept. 23, 1925. Automatic exchange systems.- A digit-absorbing selector, particularly for use in tandem-trunking systems in which the same number of digits is used for calls to all exchanges whether reached directly or through an intermediate exchange, is arranged to restore itself completely both electrically and mechanically in response to a particular digit so that it will continue to absorb the same digit an indefinite number of times. Fig. 2 shows such a selector designed to absorb the digit 2. The circuits are mainly of standard type with the addition that when the switch is raised to the second level, springs 9. 10 are operated to open the circuit of the stepping relay 5 and to prepare a circuit for the release magnet 7 which is operated as soon as the vertical series relay 4 relapses. Fig. 1 shows a layout diagram for four exchanges 22 - - 55, all calls between the exchanges 22, 44, 55 being extended through the tandem exchange 33. The numbers characterizing each exchange indicate the two digits which are always sent to reach that exchange. For example, exchange 44 is reached from exchange 22 over the fourth level of the first selector L at the exchange 22 and the fourth level of the selector I<1> at the tande m exchange 33. For calls from exchange 22 to the tandem exchange 33 the two digits 33 are sent, but the second which is unnecessary is absorbed in the selector I<1>. Similarly for a call in the reverse direction the second digit 2 is absorbed in the selector I. For local calls within an exchange, both exchange designating digits are absorbed by the selectors L, L<1>, &c., which then respond to the third digit to select a local connector C, C<1>. In a modified arrangement, the tandem office may have only one designating digit so that the incoming selectors I<1> - - I<3> are not of the drop-back type, and, in a further modification, direct trunks may run between all exchanges, in which case each exchange is characterized by only one digit and adsorption takes place only on local calls. With the latter arrangement, and when extension becomes necessary, the local selectors may be replaced by selectors of the type described in Specification 165,782, in which the switch is only restored when it receives a particular digit for the first time, so that levels such as the second level in office 22 need not be left dead but may be wired to the connectors. In the two-digit tandem system shown in Fig. 1, the local selectors which are released twice from the critical level and then hunt when raised to this level for a third time may be employed, this arrangement also permitting local connectors to be wired to the critical level.
