Abstract: A side stream subsystem can be used to remove impurity species from the recirculating alkali metal chloride solution in certain electrolysis systems. Silicon and/or aluminum species can be removed via precipitation after introducing an alkali metal hydroxide and magnesium chloride in a side stream line in the subsystem. The invention can allow for a substantial reduction in raw material and capital costs.

Abstract: A virtual machine manager (VMM) provides an emulated printer to a guest operating system. The virtual machine manager is configured to receive a printer mechanism type, receive an output type, and configure the emulated printer according to the printer type, printer mechanism type, and output type. The VMM, in one embodiment, also provides a virtual communication channel over which a guest operating system may identify and communicate with the emulated printer. The guest operating system installs a printer driver corresponding to the emulated printer, prints an object to the emulated printer via the virtual communication bus, and the VMM creates a print image of the object before communicating the print image with a target destination.

Abstract: An installer installing an operating system on a host computer system detects that the operating system is to be run under a hypervisor, and causes at least one configuration parameter of the operating system to be adjusted based on the hypervisor. A migration tool migrating a virtual machine from one hypervisor to another hypervisor, identifies the types of the two hypervisors, the operating system used by the virtual machine, and causes at least one configuration parameter of the operating system to be adjusted based on the target hypervisor.

Abstract: A top entry trunnion mounted rotary ball valve defining a main valve body having an upstream and a downstream ball seat assembly, the ball seat assemblies further including a soft insert seal, a ball seat, a seat retainer and a plurality of compression springs in between the ball seat and the seat retainer. A guiding groove on a cylindrical surface of each of the ball seats, having a first end and a second end at an axial distance equal to or more than a measure of retraction required so as to get a mechanical clearance to remove or assemble the ball member. Each ball seat is retracted in a recess against a force Fc of the compression springs and the mechanical clearance is created between the ball member and the soft insert seal, to remove or assemble the ball member and or any component from inside the valve body.

Abstract: A top entry trunnion mounted rotary ball valve suitable for safe in-line maintenance, comprising a main valve body having an upstream and a downstream ball seat assembly, the ball seat assemblies further comprising a soft insert seal, a ball seat, a seat retainer and a plurality of compression springs in between the ball seat and the seat retainer. A guiding groove on the cylindrical surface of each of the ball seats, having a first end and a second end at an axial distance equal to or more than the measure of retraction required so as to get the mechanical clearance adequate to remove or assemble the ball member, the angular span between the first end and the second end of the guiding groove can be less than 180 degrees or more than 360 degrees, depending on the overall size of rotary ball valve, in order to be able to manually retract in the ball seats.

Abstract: The present invention is a simple-to-use IV placement assist device with a base, finger interfaces extending from the base, and mechanical means to engage a needle hub. A catheter advancer is slidably integrated with the base to guide advancement of a catheter linearly along the insertion plane defined by the orientation of the base. In addition, a stabilizer component comprising a traction pad and means of constraining unintended movements of the needle and catheter, which is placed on the patient's skin, may be used along with the base and catheter advancer. The IV placement assist device stabilizes and guides the critical needle insertion and catheter advancement steps of a complication-prone and very common procedure.

Abstract: A rotary ball valve with an improved sealing arrangement, comprising of a valve body and a rotary ball, the rotary ball valve has a plurality of combination sealing arrangement comprising of a polarized combination cavity having a non-parallel slot and an extended groove, an add-on sealing ring and a compatible seat ring having a plurality of non-parallel concentric surfaces, when assembled. The compatible seat ring has a compatible profile so as to create a positive isolation by a surface contact between the add-on sealing ring and the extended groove and create another positive isolation by a surface contact between the add-on sealing ring and the compatible seat ring. The positive isolation prevents leakage during thermal cycling, pressure variations. The non-parallel slot and the compatible sealing ring therein prevents dislodgement of the seat ring; even in double block and bleed condition.
