Abstract: Disclosed are methods of synthesizing triazoles that avoids the use of concentrated acids in favor of carbonic acid generated from CO2 that can be practiced at ambient and/or elevated temperature and/or atmospheric and/or elevated pressures. The disclosed methods also provide a way of synthesizing triazole products that are sufficiently pure and/or of sufficient concentration whereby the reaction product(s) may not require purification or other treatment before being used in, for example, formulating water treatment compositions that will tend to suppress corrosion or as an intermediate product in a more complex synthesis.

Abstract: The described embodiments relate generally to device housings and more particularly to methods for blending multiple surfaces of a device housing during a machining process. A method is disclosed that prevents the formation of steps and allows for a smooth transition between flat and curved surfaces by using a profile cutter with an obtuse angle. The profile cutter can extend into the area in which the flat surface is desired while angling upwards and away from the part. This angle can ensure that the boundary between the flat surfaces and curved surfaces forms a shallow peak rather than a step. A shallow peak can be relatively easier to blend during a polishing operation than a step. As a result, the boundaries between surfaces can be hidden from the user of the device and the manufacturing process can be more efficient.

Abstract: An intake body, systems, and method for reducing acoustic resonance in pressure tap passages include determining and/or setting the length of the drilling tap passages to a value such that the natural frequency of each pressure tap passage is outside of or does not substantially overlap with operational frequency content of an air stream in the intake body. The intake body, systems and method reduce the possibility of exciting the natural acoustic frequencies of the pressure tap passages, and can lead to improved signal-to-noise ratio when detecting EGR flow using a delta-P measurement system.

Abstract: Methods and apparatus provide server services on a client for disconnected login on the client. Users execute a connected login sequence between the client and the server according to one of many strong authentication protocols. During such time, information on the server necessary for a successful execution of the strong authentication protocol is determined and provided to the client where it is stored in a local instance. Users thereafter disconnect from the server and login locally on the client Login information, locally provided, is verified against the information of the server so provided to the client. In this manner, users can be authenticated with a strong protocol, beyond mere password information. They can be strongly authenticated when logging-in to a laptop computing device, for example, when in a location not able to connect to a network appliance, such as a server.

Abstract: Described are seismic-resistant equipment cabinets and door latches for enabling a hinged door to remain attached to the cabinet during a seismic event of a particular intensity. The door has a latch disposed along one edge of the door. The latch includes a latch-keeper receptacle and a latching bolt disposed in the latch-keeper receptacle. The latching bolt is slideable between a latched and an unlatched position. The frame has a latch keeper assembly attached to an edge thereof. The latch keeper assembly is positioned to enter the latch-keeper receptacle when the door latches to the frame. The latch keeper assembly includes a protruding member having a tapered edge and a latching-bolt aperture to receive the latching bolt when in the latched position. The tapered edge establishes a close fit by the latch keeper assembly within the latch receptacle to limit relative motion therebetween during a seismic event.

Abstract: The present invention is a MEMS-based two-phase LHP (loop heat pipe) and CPL (capillary pumped loop) using semiconductor grade silicon and microlithographic/anisotrophic etching techniques to achieve a planar configuration. The principal working material is silicon (and compatible borosilicate glass where necessary), particularly compatible with the cooling needs for electronic and computer chips and package cooling. The microloop heat pipes (?LHP™) utilize cutting edge microfabrication techniques. The device has no pump or moving parts, and is capable of moving heat at high power densities, using revolutionary coherent porous silicon (CPS) wicks. The CPS wicks minimize packaging thermal mismatch stress and improves strength-to-weight ratio. Also burst-through pressures can be controlled as the diameter of the coherent pores can be controlled on a sub-micron scale. The two phase planar operation provides extremely low specific thermal resistance (20-60W/cm2).

Abstract: An antenna array employing continuous transverse stubs as radiating elements is described, which includes an upper conductive plate structure comprising a set of continuous transverse stubs, and a lower conductive plate structure disposed in a spaced relationship relative to the upper plate structure. The upper plate structure and the lower plate structure define an overmoded waveguide medium for propagation of electromagnetic energy. For each of the stubs, one or more transverse device array phase shifters are disposed therein.

Abstract: A transverse device array phase shifter includes an overmoded waveguide structure having a top conductive broad wall surface, a bottom conductive broad wall surface and opposed first and second conductive side wall surfaces. At least one transverse device array circuit is positioned in the waveguide circuit. Each circuit comprises a generally planar dielectric substrate having a microwave circuit defined thereon, and a plurality of spaced discrete phase shifter elements. The substrate is disposed within the waveguide structure generally transverse to the side wall surfaces. A bias circuit applies a voltage to reverse bias the phase shifter elements. The transverse device array phase shifter circuit causes a change in phase of microwave or millimeter-wave energy propagating through the waveguide structure.

Abstract: The present invention is directed to an apparatus for determining vane wear in rotary sliding vane pumps that operate using slideable vanes, while the pump is in operation. The invention includes a structure that allows a predetermined amount of leakage from a pumping chamber after a predetermined amount of vane length is worn away. The leakage produces a decrease in pump efficiency that is indicated by an indicating device. The indicating device serves to warn that an amount of vane wear has occurred that indicates pump inspection is warranted. The invention also includes a view port formed in the pump housing to allow inspection of the vanes without having to disassemble the pump.
