Abstract: A device includes a head having a material having a plurality of pores, wherein at least some of the pores from the plurality of pores each have a size that is smaller than a water molecule and larger than an air molecule such that the air molecules can pass through the pores and the water molecules are prevented from passing through the pores; and an elongated body extending from the head and having a thread on an outer surface thereof and having a conduit extending longitudinally through the elongated body to the head. The device is configured to fasten a first surface to a second surface using the thread of the elongated body.

Abstract: A fluid pump comprising a flow channel containing an fluid inlet and a fluid outlet and bounded by two side walls, a substantially planar flap positioned inside the flow channel, and an actuator capable of transmitting an oscillating force or torque to the flap, where the side walls extend from the inlet to the outlet and are substantially planar and parallel to the flap and extend beyond the downstream end of the flap towards the outlet by a distance such that ld?lf/2, where lf is the length of the flap, where the side wall separation, h, length, lw, and width, ww, satisfy the relationships: lw>h and ww>h, whereby in use, the actuator drives oscillatory motion of the flap in a direction substantially perpendicular to the side walls with motion of the flap having larger amplitude near the outlet than near the inlet.

Abstract: A microwave waveguide applicator and a method for heating, drying, or curing generally planar materials or products. The applicator comprises a waveguide having a pair of opposing broad sides perpendicular to a pair of opposing narrow sides bounding a rectangular exposure chamber. A microwave source generates and propagates microwaves through the chamber in a propagation direction and with an electric field generally directed from one broad wall to the other. Slotted openings in the narrow sides act as entrance and exit ports for a conveyor transporting a product along a conveying path through the chamber perpendicular to the propagation direction and perpendicular to the electric field. The waveguide may be ridged to focus or bend the electric field, especially for heating thin materials.

Abstract: A microwave filter and method for remotely tuning a microwave filter from one sub-band to another sub-band using metallic rings to adjust the capacitance or inductance of the resonator. In adjusting the capacitance, a plurality of metallic rings are disposed in the upper section or end of the resonator. Each ring has an RF switch that connects or disconnects each ring to ground, thereby varying the capacitance of the resonator. In adjusting the inductance, a plurality of metallic rings are disposed perpendicular to the magnetic field of the resonator. Each ring has an RF switch disposed within the electrical path of the ring that opens or closes the electrical path of each ring. By opening and closing each ring, the magnetic field of the resonator is altered, thereby varying the inductance of the resonator.

Abstract: This invention relates to cationically derivatized polycalactomannans obtained from cassia tora and cassia obtusifolia and to their use in personal care, household care, and institutional care compositions.

Abstract: A hybrid filter assembly is provided having a first ceramic triple-mode mono-block resonator, a second ceramic triple-mode mono-block resonator and at least one metallic resonator coupled to at least one of the first and second mono-block resonators. Each triple-mode mono-block resonator supports three resonant modes and each metallic resonator supports an additional mode, thereby providing a hybrid filter assembly of reduced size having more than six poles.

Abstract: A magnetic flux-enhanced control line for a superconducting flux flow transistor (SFFT). The SFFT includes a pair of superconducting electrodes which provide a voltage output, a region of weakened superconductor connecting the electrodes and a control line. The region of weakened superconductor carries a current I.sub.body and the control line carries a current I.sub.Control. The control line further has a portion thereof proximate the weakened region for providing a localized magnetic field through the weakened region as a function of I.sub.Control. The magnetic flux through the weakened region induces vortices therein which have a resistance r.sub.o. The proximate portion of the control line forms a tortuous current path whereby the magnetic flux through the weakened region is increased for increasing r.sub.o so that the output voltage of the transistor is increased without increasing I.sub.Control.
