Title: Air separation
Inventor: BUTTLE ANDREA
IPC: C01B13/02
Filed: 1991-04-18
Granted: 2001-12-25
Abstract: A compressed air stream is separated in a double rectification column 8 having a higher pressure stage 10 and a lower pressure stage 12. The lower pressure stage 12 contains a low pressure drop liquid-vapour contact means 13 having a pressure drop of less than 400 Pa per theoretical stage, for example a structured packing, to effect mass transfer between ascending vapour and descending liquid. A product gaseous oxygen stream is withdrawn from the stage 12 through an outlet 36 and is warmed to about ambient temperature in the heat exchanger 6 in countercurrent flow relationship with the compressed air stream which is thereby cooled. Refrigeration for the process is created by expansion of part of the incoming air. By using a low pressure drop liquid-vapour contact means 13 in the lower pressure stage 12, the resulting operating pressure in the higher pressure stage is able to be lower than in a conventional process enabling the incoming air to be compressed to a lower pressure (for example a pressure in the range 5 to 6 bar). At such pressures, two expansion turbines 54 and 56 are used to enable the heat exchanger 6 to be operated efficiently.

Title: Self-resetting overcurrent protection element
Inventor: ABE TOSHIAKI
IPC: H01C1/028
Filed: 1991-05-28
Granted: 1997-02-04
Abstract: A self-resetting overcurrent protection element uses an element body made up of a mixture of polymers and carbon black grafted with polymers. A resilient sheathing material covering the element body permits free expansion of the element body to permit the resistance of the overcurrent protection element to increase substantially in response to Joule's heating from high current. The sheathing materials preferably are made of elastic epoxy resins or silicone resins that allow significant expansion of the element body at the time of overcurrent protection, thus increasing the ratio of resistance in the element between an overcurrent state and a normal operating state.

Title: Method and device for acting upon fluids by means of a shock wave
Inventor: FISSENKO VLADIMIR VLADIMIROWIT
IPC: F04F5/02
Filed: 1991-09-04
Granted: 1996-06-04
Abstract: A two-phase mixture of at least two fluids which is supp-lied with subsonic velocity through associated feed lines (4, 3) is accelerated to sound velocity by means of a nozzle (2). Upon the exit from the narrowest cross-sectio-nal area (6) of the nozzle (2) the two-phase mixture is expanded in an expansion chamber (10) to supersonic veloci-ty. The two-phase mixture expanded to supersonic velocity is thereafter brought to ambient pressure substantially as a one-phase mixture after flowing off through a diffuser passage (9) by means of a shock wave built up in an outlet channel (8). The outlet channel (8) has a constant cross-sectional area the hydraulic diameter of which is as great as the hydraulic diameter of the narrowest cross-sectional area (6) of the nozzle (2) or amounts to up to the three-fold of this hydraulic diameter. An outlet (11) provided with a relief valve (22) is connected to the expansion chamber (10). After termination of a starting operation a continuous operation appears with the shock wave being stably maintained in axial direction in the outlet channel. In this manner a good mixture of the fluids can be obtained because of the angular flow and the relative velocities of the fluids, by condensation during the transition in the two-phase condition as well as by boiling and vaporization in the range of the supersonic flow and following thereto in the shock wave because of its "shattering effect".
