A shelf-front assembly has a first extruded plastic strip containing a label holder (e.g., a channel) and a second extruded plastic strip containing a vertical retaining wall. The first strip preferably has 1) a generally horizontal portion for placement on a shelf surface and 2) a label holder at a front end of the generally horizontal portion. The second strip preferably has 1) a generally horizontal floor and 2) an upward wall extending up from the generally horizontal floor.

Instruments for performing percutaneous biopsy procedures are disclosed, which have advantageous features for improving functionality and performance over prior art devices. These instruments comprise two types, single-use devices, and multiple-use devices having active tissue capture capability. Improved features include the ability to retrieve and evaluate multiple tissue samples during a single insertion procedure, without physical handling of the samples, as well as constructional features, such as a molded tissue cassette housing, variant vacuum port embodiments suited for different tissue environments, and a method for backflushing the instrument to remove biological debris, among others.

The apparatus of the present invention are directed to an selectively accessible electromagnetically resonant data storage element (implemented as a resonant tag, card, and / or embedded element), that is selectively responsive to predetermined electromagnetic interrogation thereof, that comprises a novel membrane switch component for enabling a user to selectively enable and / or disable interrogatory access to the resonant component, to protect from unauthorized interrogation thereof (hereinafter “MSRDS element”). The inventive MSRDS element comprises a top circuitry layer, a bottom circuitry layer, which includes a microchip, a plurality of contact pads and an antenna, an insulation spacer layer, a pressure layer retention component, and an optional EM / EMI shielding layer. The membrane switch may be formed through a combination of aligned and configured subcomponents of at least a portion of the element's layers. In one embodiment thereof, the pressure layer retention component may be advantageously utilized to maintain the membrane switch in a pressed down position to thereby enable the MSRDS element to function continuously (i.e., in an Always-ON security mode), until such time that the pressure layer retention component is removed. In this exemplary embodiment of the MSRDS element, for example used in conjunction with consumer products, when a consumer purchases a product that has been provided with the MSRDS element, they remove (e.g., peel off, etc.) the pressure layer retention component to change the element to an Always-OFF security mode, such that the MSRDS element is only accessible to electromagnetic interrogation thereof when the membrane switch is held down. Therefore, the MSRDS element of the present invention provides a greater level of data security advantageously balanced with convenience—it is freely accessible prior to acquisition thereof by a user, and is thereafter easily made secure by the user, who is provided with the capability of readily and selectively enabling access to the data stored therein.

A spinneret steam blanketing system for blanketing the face of a spinneret with gas. The system includes a steam distribution ring surrounding a filament array, where the steam distribution ring abuts the spin head and is removably mounted to said spin head. The steam distribution ring is removed and the face of the spinneret may be wiped clean, without the need for removing and replacing the spin pack.

A device comprising: two mutually immiscible conductive liquids arranged to form an interface therebetween; a plurality of nanoparticles localised at the said interface, the said nanoparticles each having a first region formed of a semiconductor having a first bandgap, the first region being surrounded by a second region having a second bandgap, the second bandgap being larger than the first bandgap; and means for applying an electric field to the said nanoparticles and thus, through the Stark effect, altering the optical absorption or emission characteristics of the nanoparticles.
