Patent CA-2093390-A1 (CA)
Title: Treatment of gas streams
Inventor: WATSON RICHARD W
IPC: C01B17/04
Filed: 1993-04-05
Abstract: A part of the hydrogen sulphide content of a feed gas stream comprising hydrogen sulphide is burned by a burner 2 that fires into a furnace 4. The combustion is supported by a stream of oxygen or oxygen-enriched air.      Resulting sulphur dioxide reacts with residual hydrogen sulphide in the furnace 5 to form sulphur vapour. Sulphur is condensed out of the resulting gas mixture in condenser 10. At least part of the sulphur-free gas mixture flows through a reactor 14 in which its sulphur dioxide content is reduced to hydrogen sulphide. Water vapour is removed from the resulting gas stream in a condenser 16. At least part of the gas stream now essentially free of water vapour is recycled to the furnace 4. A purge stream is taken either from immediately downstream of the sulphur condenser (as shown in Figure 1) or from intermediate the water condenser 16 and the furnace 4, or from the furnace 4 and, if desired, subjected to further treatment to remove sulphur-containing gases therefrom.

Title: Nucleic acid amplification by two-enzyme, self-sustained sequence replication
Inventor: FAHY EOIN D
IPC: C12Q1/68
Filed: 1991-11-13
Abstract: Novel methods are provided for nucleic acid amplification by continuous, substantially isothermal, self-sustained sequence replication ("3SR") utilizing RNA-dependent DNA polymerase activity, DNA-dependent DNA polymerase activity, RNAse H activity and DNA-dependent RNA polymerase activity. In one of the methods, before enzymatic activities can be provided by only two enzymes, a reverse transcriptase and a DNA-dependent RNA polymerase. The methods may employ two or three enzymes to provide the necessary enzymatic activities. Thus, in certain of the methods, an exogenous source of RNAse H, such as E. coli RNAse H, is employed in combination with a reverse transcriptase and a DNA-dependent RNA polymerase. In other of the methods of the present invention, reaction media are employed in which the inherent RNAse H activity of retroviral reverse transcriptases is effective to provide high levels of amplification so that only two enzymes, reverse transcriptase and DNA-dependent RNA polymerase, are required. Novel compositions for carrying out the methods of the present invention are also provided.

Title: Continuous melt-coating method and apparatus
Inventor: BUECHER UDO W
IPC: B05C5/04
Filed: 1993-07-02
Abstract: A method of continuously painting one side of a moving substrate metal strip (1) utilizing a thermosetting polymer based paint composition comprises pre-heating the strip in a pre-heat furnace (2) to a pre-heat temperature above the glass transition temperature of the paint composition, driving a solid block (8) of the paint composition into collision with the strip at a predetermined block speed to cause liquid paint to be melted from the block and applied to the strip at a precisely controlled deposition rate. The deposit, which for thin paint coats is discontinuous, is then spread over the surface of the strip by a pressure roll (14) and emerges therefrom as a smooth coat of wet paint. A bead of liquid paint (17) builds up on the strip on the up stream side of the pressure roll and the block speed may be adjusted in response to the bead size. The emergent strip then travels through a paint curing furnace (5) and a bath (6) to complete the process.
