Title: Improvements in liquid heaters
IPC: F24H1/22
Filed: 1948-01-10
Abstract: 644,472. Electric flow heaters. OLDHAM, F. E. Jan. 10, 1948, No. 842.

Patent GB-249948-A (GB)
Title: Improvements in or relating to thermionic valves
IPC: H01J21/00
Filed: 1925-01-10
Abstract: 249,948. Crowther, H. L., and Hecht, N. F. S. Jan. 10, 1925. Vacuum tubes.-A transmitting valve has its electrodes designed so that the filament, which is of thoriated tungsten or molybdenum, can act as a dull emitter. The anode is larger in proportion to the size of the filament than in the ordinary receiving valves, while being smaller than the anodes of valves with similar thoriated tungsten filaments acting as bright emitters. It should be just large enough to dissipate the heat developed. When the anode and grid of such a valve are connected, and an increasing voltage applied to them, the power dissipated at the anode increases up to a certain value of the voltage and then does not further increase with rise of voltage. The valve may be used with a voltage equal to or greater than that at which the maximum power is dissipated. The filament energy consumption is less than that of a bright emitter, transmitting valve of the same power and anode area, while the filament has a larger diameter than a bright-emitting filament of the same heating power consumption and of maximum life. Before use, the filament is heated at dull-emitter temperature, with the anode and grid unconnected, until the emission is found to be constant. For a filament consumption of 12 watts, an anode voltage of 2000, and anode dissipation 1 kilowatt, the molybdenum anode has a surface area of 400 sq. cm. Thus the ratio of the anode surface to the product of the anode volts and filament power consumption is about six times as high as in a bright-emitter, and is of the order <1>/24 k, where k is the maximum safe anode dissipation in watts per sq. cm. The grid should be of very open construction, to allow a large negative potential to be applied, so as to protect the filament from destruction of the dull-emitter properties. Or an additional open grid may be provided, between the ordinary grid and the filament; a current may be passed along it to reduce the potential gradient. If the valve stops oscillating while under a high voltage, the dull-emitting property is destroyed, but may be restored by continuous heating as in the original preparation of the valve.

Title: Tubular thermoelectric generator module
IPC: H01L35/32
Filed: 1975-01-09
Abstract: 1464843 Thermoelectric generators M A MARKMAN L M SIMANOVSKY I R JURKEVICH N V KOLOMOETS V T KAMENSKY I M MATSKOV and S I MAXIMOV 9 Jan 1975 988/75 Heading H1K A tubular thermoelectric generator has an inner thermal conductor 1 embraced by annular thermopiles 2 interconnected by strips 10 and an outer thermal conductor which includes a number of annular taper clamps 3 each embracing a thermopile 2, with electrical insulation 4, 5, 6 insulating one thermocouple from another and from the inner and outer conductors. As shown, each taper clamp has an inner and an outer ring, the inner one, e.g. of Al or Cu, being split and having an initial diameter less than the minimum outer diameter of the thermopiles 2. The outer ring, e.g. of Ti, plastically deforms to provide a good thermal contact with an outer jacket 7. Each thermopile includes P and N sectors 11, 12, Fig. 2, connected in series circumferentially by busbars 13, 14, current connection being made to leads 9 by the strips 10. The inner conductor 1 carries a hot medium and the cold carrier flows around the jacket 7 so that the thermal flow is radial through thermopiles 2 and insulation 5, 6. As the conductor 1 thermally stretches, corrugations in the jacket 7 yield and good thermal contact is maintained by changes in the taper clamps 3.

Filed: 1989-01-06
Abstract: PURPOSE:To obtain the liquid crystal display element which has no unequal display and has good display quality by connecting the liquid crystal display element and an integrated circuit for driving by means of an anisotropic connector for which metallic particles are used. CONSTITUTION:Plural pieces of conductive patterns P1 to Pn which electrically connect plural pieces of external connecting terminals T1 to Tn provided on a glass substrate 1 of the liquid crystal display element and plural pieces of partial display electrodes formed by combining the patterns to be displayed at the time of respective displays are respectively changed in pattern width W1 to Wn according to the distances between the external connecting terminals T1 to Tn and the partial display electrodes. The electric resistance between both is maintained nearly constant regardless of the distances between both. The voltage drop generated therein is, therefore, maintained constant as well as the voltage impressed to the respective partial display electrodes is maintained constant as well. The unequal display is not admitted in this way even if the threshold characteristic is steep. The liquid crystal display element having good display quality is thus obtd.

Abstract: PURPOSE: To obtain double sealing structure without any inconveniences for cover mounting, by bending with an acute angle the lower part of the cover that is a little longer than the distance between the cover and the pile, and applying elastic sealant on the inside of the part.  
     CONSTITUTION: The water tide area of the steel pile structure 1 of a port etc. is covered by the cover 2. The lower part 3 of the cover 2 is bent inside with an acute angle, with the length of the bottom part 3 a little longer than S, the distance between the cover 2 and the pile 1.

This cover 2 easily covers the pile 1. After mounting the anticorrosive cover 2, the circular space is implanted with highly expansive filler 6. When the cover 2 expands a little, the circular body 4 is completely adhered to the surface of the pile 1. Further, the bottom part 3 expands downward by the expansive power of the filler and its end is firmly pressed to the surface of the pile 1, so that the double sealing structure is formed beteen the cover 2 and the pile 1.
