Abstract: It is known to desulphurise flue gases by passing them through a scrubber. In order to achieve the necessary chimney temperature of the clean gas stream, the heat of the crude gas stream is utilised which can be transferred to the clean gas stream via a heat displacement system. As long as the temperatures lie above the dew point of sulphuric acid, materials such as steel can be used for this. However, difficulties result if the temperatures are below the dew point of sulphuric acid, so that special measures have been found. 
<??>The invention now provides staggered heat displacement systems 13, 14, in which, initially, in a relatively high temperature range, heat exchangers 3, 7 made of steel are connected together via a heat transport medium and, in a downstream second heat displacement system 14, heat exchangers 4, 6 made of corrosion-resistant and antiadhesive plastics are used.

Inventor: MOHLA PREM P
IPC: C21C1/10
Filed: 1979-10-02
Abstract: A method of making a more economical and reliable treating agent for use in late metal treatment when pouring metal castings. The treating agent is defined as an essentially homogeneous solid cast block preferably containing alloying ingredients to nodulize or inoculant ferrous metal. Each block is designed to present a generally uniform reaction surface to molten metal to be treated. This is obtained by casting the block to a shape which snugly fits a prepared basin in the mold gating system over which the molten metal to be treated must flow, or to cast the block in an annular configuration through which the molten metal must flow. The latter block has contoured inner surfaces which maintain a generally constant reactive surface as the block is consumed. These blocks are preferably prepared by simultaneously casting a large number in closely nested relation. Each mold for said blocks receives molten material, out of which the agent is formed, from a common sprue; runners interconnect the mold cavities and sprue, for example, in a simulated "Christmas tree" arrangement. The gating system and mold cavity pattern, for casting the treating agent to a special shape are all comprised of a material that will vaporize upon contact by the molten treating agent, such as polystyrene. The unitary tree structure of foam patterns and gating system is placed in a flask and surrounded by unbonded heat absorbing particles, such as sand or steel shot. Rapid solidification is assured by the selection of heat absorbing particles and by the use of the vaporizable patterns to avoid noticeable segregation in the alloy blocks. The blocks formed for the treating agent are characterized by increased homogeneity, absence of undesirable segregation, absence of internal oxidation, and absence of organic or refractory impurities; the blocks are less costly to make both as to capital requirements and operating expenses.

Abstract: A welding rectifier is connected to an a.c. power supply. The rectifier delivers a pulsating voltage which during a part of a period is too low to maintain the arc established between a welding electrode and a work. A main winding of an ironcored inductor is connected in series with the rectifier, the welding electrode and the work. An auxiliary winding is wound onto the iron core and connected in series with a capacitor. The auxiliary winding is connected to the main winding so that the two windings, when passed by a current, supply ampere-turns in the same direction. The auxiliary winding and the capacitor are connected in parallel with the main winding and the arc. The capacitor is also connected in series with a charging rectifier connected to the a.c. supply. The capacitor is discharged through the auxiliary winding and the main winding into the arc, when the voltage delivered by the welding rectifier is too low to maintain the arc.

Abstract: An optical connector ferrule comprises a capillary member, and a ferrule body. The capillary member is provided with a straight bore communicating from one end to the other end, and with a first slit and a second slit, respectively, for communicating the straight bore to the external of the capillary member. An auxiliary optical fiber is fixed in the straight bore of the capillary member, such that one end of the auxiliary optical fiber is aligned with the one end of the capillary member, and the other end of the auxiliary optical fiber is positioned on the central point of the first slit which is positioned on a side of the one end of the capillary member.  An optical matching material is filled from the first slit into a portion of the straight bore which is limited by the second slit, thereby covering the inserted end of the auxiliary optical fiber.  The capillary member is fixed in the ferrule body.  An optical fiber is inserted from the second end into the capillary member to be fixed in the straight bore thereof.  In this structure, the optical matching material does not propagate beyond the second slit.  Therefore, the optical fiber is stably adhered to the inner surface of the straight bore of the capillary member.
