Abstract: 1,087,963. Rotary compressors. BORGWARNER CORPORATION. Dec.20, 1965 [Dec.30, 1964], No.53946/65. Heading F1F. In a rotary sliding vane compressor, particularly for use in a refrigeration system, lubricant in the sump space 47, Fig. of a refrigerant gas chamber 16 connected through an opening 66 and a compressor discharge port 29, Fig. 2, with the working chamber 26 of the compressor, is injected under compressor discharge pressure through passages 46, 48 and grooves 49a, 49b into the working chamber at a point one vane space ahead of the position where the suction port 28 of the compressor is closed by the trailing vane of said space and where the pressure is substantially below discharge pressure. As shown, one vane is just closing the edge 28a of the suction port 28 and the vane ahead of this vane is just passing the point through which the lubricant is injected. This arrangement, prevents refrigerant gas released from the lubricantrefrigerant mixture from filling the suction space and reducing the capacity of the compressor. Lubricant also flows through clearances between the end faces of the rotor 25 and the adjacent end walls 22, 24 into the slots 38 beneath the vanes 36. As the rotor 25 rotates this lubricant is forced out of the slots through arcuate slots 55 to lubricate the bearings.

Abstract: The present invention relates to a contact process for producing sulfuric acid from gases containing more than 10% by volume SO2 and which gives a maximum amount of surplus heat in an economical manner and is utilized for an increase in the concentration of dilute sulfuric acids. This improved process comprises the following steps: (a)  combining the production of sulfuric acid with an increase of the concentration of dilute sulfuric acid; (b)  adding oxygen-containing gases to a partial stream of SO2-containing gases at such a rate that the gas mixture can be reacted at least in a first contacting tray until the reaction                            has proceeded to an equilibrium below or at the highest temperature which is permissible for the catalyst; (c)  heating said resulting gas mixture to the operating temperature of said first contacting tray by subjecting it to heat exchange with hot sulphur trioxidecontaining gases flowing between contacting trays; (d)  adding the remaining SO2-containing gas to the sulphur trioxide-containing gas from at least the first contacting tray of the first catalytic reaction stage; (e)  controlling the rate at which the partial stream of SO2-containing gases is fed to, the first contacting tray so that SO3 is produced in step (b)  at such a rate that the ratio of SO2:SO3 in the mixture produced in step (d) is such that the reaction in the following contacting trays can proceed to an equilibrium below or at the highest temperature which is permissible for the catalyst; (f)  removing SO3 from the catalytically reacted gases by interstage and final absorption at operating temperatures of 100-200.degree.C; (g)  conducting the catalytic reaction in the second catalytic reaction stage in at least two contacting trays and cooling the gases between the contacting trays; (h)  expelling water from the dilute sulfuric acids by directly contacting the acids with hot gases consisting of the contact process exhaust gases which have been subjected to final absorption or of inert gases having a low water content, or a mixture thereof; (i)  heating the expelling gases with at least part of the heat which becomes available in the final heat exchanger, which follows the second catalytic reaction stage; (j)  heating the expelling gases with at least part of the heat which becomes available during the cooling of the catalytically reacted gases in step (g) or with at least part of the heat which becomes available in the second cooling stage which follows the first catalytic reaction stage and precedes the interstage absorption, or both and (k)  using the heat energy derived from the acids which are circulated through at least one of the devices in the group comprising the dryer, the interstage absorber and the final absorber so as to increase the concentration of or to preheat the dilute sulfuric acid, or both.

Inventor: HOPPER T P
IPC: E06B9/00
Filed: 1977-07-26
Abstract: An apparatus for insulating against conductive, convective, and radiant heat transmission comprises a plurality of substantially non-transparent and generally parallel sheets. The sheets may be attached to a retracting device from which they can be drawn to extend and cover a building opening such as a window or onto which they can be retracted to uncover the opening. A number of spacers which may be in the form of collapsible or nestable devices are mounted within the apparatus to separate each pair of adjacent sheets and, thus, define a dead air space therebetween. At least one of the sheets has a surface, facing on the dead air space, that exhibits a low surface emittance. This surface emittance is sufficiently low to yield a total effective emissivity of the surface and dead air space of no greater than 0.60. Importantly, the spacer devices are designed so as not to abrade or otherwise harm the reflective surface. The combination of these dead air spaces with the low emittance surface synergistically results in an apparatus having low total effective emissivity that effectively impedes radiant heat transfer. The dead air spaces also effectively impede conductive and convective heat transfer.

Abstract: The invention relates to a method for recovering the valuable metal content of a mix of contaminated copper raw materials, of which materials at least one is sulphide bearing, and which contain one or more impurities forming the group arsenic, antimony, bismuth, mercury, tin, chlorine and other halogens. The invention is characterized by adjusting the halogen content of the mix so that it is substantially at least stoichiometric in relation to remaining impurities in the group, whereafter the mix is charged to a furnace in which melting can take place and in which the mix is heated to at least 500°C, but beneath the melting points of respective ingredients of the mix, while maintaining good contact with hot gas therewith to expel substantially all of the aforementioned impurities present. The mix is then heated to completely smelt the ingredients present, to form a slag and a copper matte, which latter contains the valuable metal content, whereafter this valuable metal content is recovered with the aid of a suitable, conventional method.At least one of the copper raw materials present in the mix comprises suitably a halogen-bearing valuable-metal containing product, for example chlorine-bearing ash or slag.
