Title: Air separation
Inventor: OAKEY JOHN DOUGLAS
IPC: F25J3/04
Filed: 1996-03-15
Granted: 1998-07-09
Abstract: A stream of precooled and purified air is introduced through an inlet 2 into a double rectification column comprising a higher pressure rectification column 4 and a lower pressure rectification column 6 and is separated therein into an oxygen-rich fraction and a nitrogen-rich fraction. A stream of argon-enriched oxygen vapour flows from an outlet 70 of the lower pressure rectification column 6 into a side column 52 in which argon is separated therefrom. An oxygen-enriched liquid air stream is taken from an outlet 16 at the bottom of the higher pressure rectification column 4. A vaporous oxygen-enriched air stream is introduced into the lower pressure rectification column 6 through an inlet 46 above the outlet 70. At least part of the oxygen-enriched liquid is partially reboiled in a reboiler 22 and separated in a further rectification column 28, thereby forming a vapour depleted of oxygen and a liquid air stream further enriched in oxygen. At least one stream of the further-enriched liquid is vaporised to form the oxygen-enriched vapour that is introduced through the inlet 46 into the lower pressure rectification column 6. A part of the oxygen-depleted vapour is condensed and is taken as product or reintroduced into the lower pressure rectification column 6. The partial reboiling in the reboiler 22 is effected by indirect heat exchange with a stream withdrawn through an outlet 200 from an intermediate region of the side column 52. <IMAGE>

Granted: 1995-09-28
Abstract: A testing circuit is provided for testing the operability both of a load (30) and of a capacitor (26) incorporated into a main detonator circuit and arranged to discharge into the load for detonation thereof. A test pulse is generated at a central controller to which a ring of detonators is connected on a harness. The test pulse is routed via the harness for storage in the capacitor. A controlled switch (44) is operated to allow the capacitor to discharge into the load. A transistor (52) is operated by the discharge signal, the transistor having an output for delivering a discharge value signal (56) in response to the discharge signal remaining above or falling below a threshold value. The discharge value signal is latched and is in turn used to inhibit a local oscillator (66). The inhibited signal from the oscillator is routed back to the controller so as to indicate a fault either in the capacitor (26) or in the load (30). <IMAGE>

Title: Mixer drive apparatus
Inventor: HUTCHINGS WILLIAM F
IPC: B01F15/00
Filed: 1987-03-20
Granted: 1989-06-22
Abstract: Mixer drive apparatus, which provides gear reduction for driving the impeller shaft of the mixer. A drive shaft (22) from an electric motor (18) is parallel to the impeller shaft (34) which extends through a support collar of a housing where the collar has a hole therethrough into which the impeller shaft extends into the housing. A hub (38) is rotatably mounted on the outside of the housing (10) and carries a gear (42) which is coupled to a pinion on the motor drive shaft. A coupling (70) is attached to the hub and bridges the hole in the collar. The end of the impeller shaft is cantilevered and overhung from the coupling. A gap is defined between the impeller shaft and the inside surface of the support collar which is adapted to receive a seal assembly. The seal assembly (30) includes a retainer hub which captures a sleeve containing the seal structure in the gap between the coupling and the retainer. The seal sleeve (40) may readily be removed upon disassembly of the coupling, which has two sections defining a split ring which clamps the upper end of the impeller shaft, and has a thrust plate with a bolt therethrough into the end of the impeller shaft for axially adjusting the location of the shaft so as to bring the seal sleeve into engagement with the coupling for rotation therewith. A support collar on the impeller shift engages the retaining hub when the coupling releases the shaft for the removal and replacement of the seal sleeve assembly. A seal captured by the collar engages the retainer hub and provides a pressure seal to facilitate replacement of the seal sleeve when the mixer is used with a pressurized vessel.
