Patent GB-999800-A (GB)
Title: Purification of gases
Inventor: NICHOL ROBERT JAMES
IPC: B01D53/52
Filed: 1962-03-13
Abstract: Hydrogen sulphide is removed from a gas, e.g. town gas, by washing the gas with an aqueous solution of ferric and ferrous iron chelates, which comprise iron chelated with a polyamino carboxylic acid chelating agent, the solution being regenerated by oxidation with a free oxygen-containing gas, e.g. air or oxygen, the regeneration being so controlled that a substantial proportion of ferrous iron chelate remains in the regenerated solution.  The proportion of ferrous iron chelate remaining should be 15 to 75%, preferably 20 to 50%, of the total iron present, and the volume of air or oxygen used for regeneration may be varied manually or automatically to maintain the correct proportion of ferrous iron chelate, which may be determined by chemical analysis or by measuring the redox potential of the solution.  The air or oxygen may be mixed with the gas to be purified before contacting the gas with the solution, purification and regeneration occurring simultaneously, or may be mixed with an inert gas, e.g. the purified gas, for contacting the used solution, or the methods may be combined, e.g. when the free oxygen content of the purified gas must be kept below a level which does not allow sufficient regeneration of the solution to take place during purification. In the latter case, the further regeneration may be carried out under pressure.  The chelating agent may be an amino acid as described in Specification 999,799.  The reoxidation step may be additionally controlled in relation to the oxygen content of the gas entering and leaving the washing plant, but no details are given. Specification 855,421 also is referred to.

Title: Improvements in or relating to methods of manufacturing electric discharge tubes
IPC: H01J21/36
Filed: 1952-04-17
Abstract: 706,237. Thermionic valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 17, 1952 [April 20, 1951], No. 9690/52. Class 39(1) A method of manufacturing an electric discharge tube for use at short wavelengths and comprising plane electrodes, more particularly for adjusting the correct spacing between a grid electrode having a plurality of equally spaced parallel wires and another plane electrode, is characterized in that the electrodes are first brought to approximately the correct spacing by adjusting their mutual capacity, a light beam is directed in an inclined position from the side of the grid wires so that they throw shadows on the surface of the other electrode, and the electrodes are adjusted so that projection of each grid wire exactly coincides with the shadow of another grid wire, which occurs when the spacing is correct. In the Figure the cathode 1, which is preferably a metallic cathode activated by diffusion of electron-emitting material, is supported from a flange 4 provided with three apertures through which it is bolted to a sealed-in plate 7. The electrode assembly may be placed in a holder 16 provided with means for adjusting the nuts 6 which control the position of the cathode. The cathode is adjusted to approximately the right position by adjusting its capacity to the grid, a beam of light 17 is directed on to the grid, and the cathode is finally adjusted so that each grid wire lies directly above the stadow of another grid wire. The cathode may then be secured in position by welding, cementing, or soldering the nuts 6. It is advantageous to provide solder on the support 3 so that it can flow between the flange 4 and the plate 7 and secure these parts with respect to each other. The grid may comprise 100 wires of 12Á diameter with spacings of 50Á, the cathode-grid spacing being 40Á. The method may be applied to adjusting the spacing between two grids the wires of which are at right angles to each other.

Filed: 1971-04-19
Abstract: 1347848 Rolling DEMAG AG 19 April 1971 [20 April 1970] 9909/71 Headings B3M [Also in Division B8] Rolled products are transferred from a cooling bed 1 to a roller conveyer 2 by a transfer device comprising a set of endless, parallel belts 5, having upper and lower runs and notches 5a, which are movable between a position in which parts of the upper runs of the belts 5 are above the conveying plane of the conveyer 2 and a position in which the upper runs are below the conveying plane. In operation a bar leaving the cooling bed 1 enters the first notches on the right hand end of a section 3a of a set of parallel belts 3. The speed of movement of the belts 3 is sychronized with the movement of the cooling bed 1 so that each notch of the section 3a is filled. The belts 3 are then accelerated until the right hand end of a further section 3a reaches the delivery side of the cooling beds whereupon the speed of the belts is reduced so that the section may be loaded. During movement of a loaded section 3a from positions A to B, the belts 5, moving at the same speed as the belts 3, are in the lowered position. The belts 5 are then pivoted upwardly about shaft 7 so that a section 5a takes the bars and conveys them to a position above the conveyer 2 whereupon the belts 5 are pivoted downwardly so the bars can be removed by the conveyer 2. If flat bars are to be conveyed the speed of the belts 3 and 5 is adapted so that the bars are placed on the flat sections 3b. In another embodiment the transfer apparatus comprises a single set of belts 5, pivotable about a vertical plane as above, but which extends to the delivery side of the cooling bed.

Title: Data packet sending device, and data preserving method for the sending device
Inventor: MUKAI AKIRA
IPC: H04L47/20
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To preserve the new data without destructing them in order to output this data as the packet data by breaking the 1st data to entry the 2nd data in the 1st rank in a queue buffer and then sequentially shifting the following data when the number of entries reaches the prescribed value in the queue buffer and the new data received later is more significant then the earlier one. SOLUTION: When a data registering request signal 109 is asserted, a queue control circuit 105 decides whether the number of entries comes to n in a queue buffer 106, i.e., the buffer 106 is filled with the entries. If the number of entries has come to n in the buffer 106, the circuit 105 breaks the 1st data and enters the 2nd data in the 1st rank to sequentially shift the following data in the buffer 106. Thus, the significant new data are never broken and stored in the buffer 106 to be outputted as the packet data.
