Abstract: A method and apparatus for detecting and measuring suspended solid particles in a molten metal, even if the metal also contains liquid and/or gaseous inclusions. The method involves moving molten metal through an orifice of predetermined hydrodynamic diameter provided in an electrically non-conductive barrier. As the molten metal is moved through the orifice, a current path is established by passing a current through the orifice from electrodes positioned on opposite sides of the barrier. Changes in voltage of the current are measured as the metal is drawn through the orifice, and the number of particles suspended in said metal drawn through the orifice is detected from the voltage changes. The metal, immediately before being moved through the orifice, is conveyed through a passage defined by an electrically non-conductive surface positioned in the current path, the passage including a region having a hydrodynamic diameter of between 2 and 10 times the hydrodynamic diameter of the orifice, at least a part of the region being of substantially constant hydrodynamic diameter. The provision of the passage upstream of the orifice has the effect of removing substantially all liquid and gaseous inclusions from the molten metal before the metal passes through the orifice.

Abstract: The cable caddie is an apparatus for organizing, storing and porting cables and is made from a durable flexible fiber strap piece between 3 and 6 feet long forming the base layer, a terminal or handle coupled to at least one end of the strap, and at least one Velcro strip piece with one end of the strip piece coupled on to the flexible strap base layer and the distal end having the mating Velcro fiber forming a loop when mated when the distal end is folded upon the coupled end. Wrapped or wound cable are held in the Velcro strip loop formed when the strip is folded over the wrapped cable loops and onto the mating Velcro side securing the cable loop to the base layer. Several such Velcro strips for easy looping about and securing the cables to the base strap carrier, can provide organization and allow easy porting of many cables, as the base strap can be rolled up and carried by the handles attached.

Abstract: A lightweight, substantially unpadded, comfortable, push-in underwire bra has, when worn by a female wearer, a front including a pair of cups. Each cup defines upper inner and outer portions, lower inner and outer portions, a top and a bottom, and is configured and dimensioned to hold substantially one breast of a female wearer. Each cup defines an underwire-receiving channel extending downwardly from the cup upper outer portion and then inwardly across the cup bottom to the cup lower inner portion where the channel terminates. A single underwire-free channel extension connects the channels of the cups only at the lower inner portions thereof, the cups being connected at the front only by the channel extension, thereby to provide a deeply plunging cleavage and enable substantial independent motion of the cups relative to one another. For each cup, a thin, arcuate underwire is disposed in the channel and biases the cup upper outer portion inwardly. Thus, the underwires bias the cup upper outer portions inwardly to provide push-in cleavage on the wearer's breasts. Straps are secured to the front for releasably supporting it on a female wearer with the breasts of the female wearer substantially within the cups.

Abstract: An electrically-tunable optical filter has an optical cavity that forms an absorption peak in light that is incident on the filter. The optical cavity includes a layer composed of a material with a high electro-optic coefficient so that the index of refraction of the layer changes in response to a voltage applied by a controller. By adjusting the voltage, the controller can control the index of refraction so that an absorption peak of the filter can be tuned as may be desired without having to alter the physical structure of the filter.

Abstract: The current invention relates to a flexible toothbrush with a rigid handle support that is also compact in size and shape and can be safely used by prison inmates. In order to allow for adequate handle length and still allow for the required radial, axial, and rotational direction flexibility, there needs to be in place on or more structural units within the elongated body and handle portions of the toothbrush that also provide enough support and rigidity in the longitudinal direction so that the user can accomplish the task with the same feel and ability accomplished with conventional toothbrushes that possess rigid thermoplastic or thermoset handles. For the purposes of the present application, a truss is a structure comprising one or more triangular sections provides the necessary support along the longitudinal length of the handle while still allowing enough flexibility that the toothbrush cannot be used as a weapon.
