Title: Improvements in methods of preserving the interior of steam boilers
IPC: F28G9/00
Filed: 1953-10-02
Abstract: 731,137. Preventing corrosion. RIEXINGER, O. Oct. 2, 1953 [Oct. 3, 1952], No. 27016/53. Class 123 (1). Steam boilers are protected against corrosion whilst shut down by providing an oxygen-free atmosphere in the boiler, the partial vacuum produced when the boiler, with the water at normal level, is cooled down being filled with an inert gas. The gas, for example, nitrogen, is supplied from a cylinder which may be connected permanently to the boiler steam space by a valvecontrolled pipe. As the boiler cools the valve in the gas supply pipe is opened whilst a slight pressure still exists in the boiler, the inert gas flowing into the steam space as the steam therein condenses. Alternatively, Fig. 1, the gas consists of combustion gases produced as air is drawn through a bed 5 of glowing charcoal, the gases flowing through pipes 1, a cooler 7 and the boiler air-extracting valve 2 into the boiler drum 3.

Alloys containing iron oxide are prepared by compacting mixtures of the constituent powders after an optional pre-reducing step and sintering at up to 1400‹ C in hydrogen. In either preparation, the resulting material is extended. The yttrium or yttrium oxide is normally present in the alloy as in yttrium-rich particles having an inter-particle spacing of less than 5 microns.

Abstract: 737,775. Thermionic cathode tubes. WESTERN ELECTRIC CO., Inc. Oct. 9, 1953 [Oct. 17, 1952], No. 27812/53. Class 39 (1). A tube for broad band amplification comprises an input transmission line 10, Fig. 1, and a parallel output transmission line 17, the input line having a plurality of control grid sections 12 connected by impedances 13, and the output line having a plurality of anode sections 19 connected by impedances 20, a common cathode 11, and a common screen grid 28, the whole forming a series of electron discharge tetrodes enclosed in a single envelope; the two transmission lines are of like phase velocity, and so coupled by the electron streams that a wave travelling along the input line gives rise to a corresponding amplified wave along the output line. In the embodiment shown, the input line comprises a ceramic cylinder 34 having one flattened surface in which is cut a channel 35. The grids consist of sets of wires 36 sealed across this channel, the sets being advantageously separated by slight cuts 40. The intervening inductances 13 are formed by single wires or metallized bands 38 extending spirally round the cylindrical ceramic surface from one set of wires to the next set. In the channel, below the grids, lies the cathode 42. A similar ceramic cylinder 46 forms the output line, with the anodes comprising sets of wires or plates, connected by similarly formed inductances, and with a dummy cathode 50 lying in the groove behind the anodes. By fabricating the two transmission lines of the same material, and arranging that the anode to dummy cathode spacing is the same as the cathode to grid spacing, the impedance levels of the two lines may be made the same, if required, although a higher gain is attainable if the impedance level of the output line is higher. Insulating spacers 56 rest on stepped portions of the ceramic cylinder, as at 44. The cathode and dummy cathode are urged against these spacers by springs 64, which gives the predetermined cathode spacings referred to above. The springs slide over metal posts 58 which pass completely through the assembly at each end. A grounded screening grid 28 separates the lines, so that the only communication between them is provided by the electron streams in the respective tetrodes. The screen grid is mounted on a frame which has side extensions 55 to prevent coupling between the lines due to stray fields.

Convention date, Oct. 10, 1932. [Class 146 (iii).] A writing-instrument for use as a fountain pen or stylo, and for marking on smooth or rough material without catching or tearing, is provided with a ball marking-element 6 in conjunction with a regulating-ball 7 and a ball valve 8, the marking and regulating balls being arranged in a chamber of corresponding diameter in the conical point-section 2 which terminates in a bead for retaining the balls in position ; the ball valve is of larger diameter and is retained in a chamber of corresponding diameter in the point section and in communication with the first chamber. The balls 6, 7 are allowed a certain amount of play axially of the pointsection, the amount being adjustable by means of an abutment 14 for the ball 8 which can be forced down on to its seating to prevent the flow of ink. The abutment 14 is formed on the end of a screw 11 secured by a nut 12 in the end of a tube 9 screwing into the barrel 1 and secured by a screw 19 in an operating-cap 18. The movement of the tube 9 in the barrel is limited by a stop 20. An enlarged part 12<1> is formed on the screw 11 and acts to guide the screw in its movements, passages 13 for the flow of ink being provided. The ink is contained in the tube 9 in the wall of which apertures 15, 16 are provided to permit ink to pass to the marking-point, and screw-threads 17 are formed on the tube so that when the tube is unscrewed to release the valve the screwthreads tend to exert a pressure and force ink to pass under the ball 8. The tube 9 extends slightly beyond the end of the cap 18 and is closed by a cap 23 and packing 24 through which an air-tube 25 passes. Leakage of ink from the barrel 1 is prevented by packing 22. The bead for retaining the marking- ball in place may be formed on the pointsection, or may be made of iridium or other hard material and secured to the point-section.
