Fluid dynamics video of domains with spiral dislocations formed in the wake of an enslaved phase-separation front
Enslaved phase-separation fronts that move with a speed just smaller than
that of a free front will leave in their wake a morphology of alternating
domains that are roughly aligned with the front. However, these alternating
domains will typically not be in phase initially. Instead there are defects.
Here we present novel phase-separation morphologies that are formed in such
systems where the defects are reminiscent of spiral dislocations in crystal
growth.Comment: 1 pag
Pressure-control purge panel for automatic butt welding
Modification of a purge panel for use in an automatic butt weld reduces the drop in pressure between the regulators and the weld head and tube purge fitting. The invention affects air regulators for plants, regulating circuits for pneumatic valves, and automatic welding machines
Inverter ratio failure detector
A failure detector which detects the failure of a dc to ac inverter is disclosed. The inverter under failureless conditions is characterized by a known linear relationship of its input and output voltages and by a known linear relationship of its input and output currents. The detector includes circuitry which is responsive to the detector's input and output voltages and which provides a failure-indicating signal only when the monitored output voltage is less by a selected factor, than the expected output voltage for the monitored input voltage, based on the known voltages' relationship. Similarly, the detector includes circuitry which is responsive to the input and output currents and provides a failure-indicating signal only when the input current exceeds by a selected factor the expected input current for the monitored output current based on the known currents' relationship
Phase ordering of two-dimensional symmetric binary fluids: a droplet scaling state
The late-stage phase ordering, in dimensions, of symmetric fluid
mixtures violates dynamical scaling. We show however that, even at 50/50 volume
fractions, if an asymmetric droplet morphology is initially present then this
sustains itself, throughout the viscous hydrodynamic regime, by a
`coalescence-induced coalescence' mechanism. Scaling is recovered (with length
scale , as in ). The crossover to the inertial hydrodynamic
regime is delayed even longer than in ; on entering it, full symmetry is
finally restored and we find , regardless of the initial state.Comment: 4 pages, three figures include

CP-Violating MSSM Higgs Bosons in the Light of LEP 2
In the MSSM, the CP parities of the neutral Higgs bosons may be mixed by
radiative effects induced by explicit CP violation in the third generation of
squarks. To allow for this possibility, we argue that the charged Higgs-boson
mass and tan(beta) should be used to parametrize the MSSM Higgs sector. We
introduce a new benchmark scenario of maximal CP violation appropriate for
direct searches of CP-violating MSSM Higgs bosons. We show that the bounds
established by LEP 2 on the MSSM Higgs sector may be substantially relaxed at
low and intermediate values of tan(beta) in the presence of CP violation, and
comment on possible Higgs boson signatures at LEP 2 within this framework.Comment: 16 pages, LaTeX, 4 encapsulated figure
