Abstract: The invention concerns a probe for applying a high frequency electromagnetic energy flux on the skin through a mixture of conductive gel and a treatment product, designed to cause the treatment product to penetrate into the skin. The probe is provided with a non-conductive bearing surface (14), having a plurality of openings (6) around or in the proximity of which inductor elements (5) arranged in successive layers emit an electromagnetic field. The openings (6) emerge through an orifice (3) and contain the gel/treatment product mixture whereof the penetration into the skin is activated by the electromagnetic field. Advantageously, the probe further comprises at least one source of laser electromagnetic radiation (8) arranged inside or aligned with at least one opening (4) emerging in the bearing surface (14), so as to act jointly with the electromagnetic radiation emitted by the inductor element (5).

Abstract: Compensating for the complex changing shape and location of a turbocompressor's surge limit line can be difficult and imprecise when using antisurge controllers that do not incorporate sufficient capability. Based upon various operating conditions, surge limit line changes can be attributed to a number of process variables. These effects are particularly relevant to multistage centrifgal and axial turbocompressors operating with variable rotational speed and equipped with adjustable inlet or diffuser guide vanes, or both. This invention relates to an innovative method of antisurge control in which the function of those process variables (comprising the turbocompressor operating condition parameters) is used to calculate distances to the surge reference line. The function is formed as a superposition of the functions of lesser numbers of variables.
Abstract: The invention relates to a nitrogenous composition resulting from the enzymatic hydrolysis of an aqueous solution of maize gluten, having a ratio of the concentrations of inorganic phosphorus to total phosphorus (Pi/Pt) greater than or equal to 0.05, preferably from 0.05 to 0.5 and a ratio of the concentrations of amine nitrogen to total nitrogen (Na/Nt) greater than or equal to 0.025. The invention also relates to the use of a nitrogenous composition according to the invention in culture media for microorganisms which produce, in particular, organic acid.

Abstract: A two-stage ejection system for an injection mold that allows the mold plates to move at the same time and then allows selected plates to be stopped in a locked position while the other plates continue to move. The system includes an external bushing, an internal bushing that carries cam retainers, and an ejector pin. The system may be used in an injection mold having in sequence a stationary plate, a stripper plate, a support plate and an ejection plate. The external bushing is secured to the support plate, the internal bushing is secured to the stripper plate, and the ejector pin is secured to the ejection plate. The cam retainers selectively engage grooves in the external bushing or ejector pin to lock their respective attached plates from moving with respect to each other while the other plates continue to move.
Abstract: A plastic bag holder (10) for installation on a cabinet door (200) wherein the holder (10) comprises a mounting unit (11) including an inverted generally U-shaped bracket member (20) dimensioned to receive the top (201) of a cabinet door (200) and a support unit (12) formed integrally with the mounting unit (11) and including a generally C-shaped bag support member (40) having a base portion (41) and a pair of mirror image outwardly projecting curved support arms (42) (42′) having a generally cruciform cross-sectional configuration over a substantial portion of their respective lengths; wherein the opposed ends of the support arms (42) (42′) define a front opening in the support unit (12) that is dimensioned to allow the passage of the upper end (101) of a plastic trash bag (100) to pass through said front opening.
Abstract: A vehicle noisemaker device and method are provided according to the invention. The vehicle noisemaker device includes a gas supply configured to be removably affixed to a vehicle, with the gas supply including at least one gas supply outlet. The vehicle noisemaker device further includes at least one nozzle. The at least one nozzle creates a flatulation sound effect. An at least one outlet valve is positioned between and communicates with the at least one gas supply outlet and the at least one nozzle for allowing the gas to be released from the gas storage tank. The vehicle noisemaker device preferably also includes a controller communicating with the at least one outlet valve and controlling a release of the gas from the gas storage tank. The controller is preferably manually triggered and opens the at least one outlet valve to create the flatulation sound effect.
Abstract: On the rotor, between each blade integral with its folding mount and the member for linking with the hub, an electrical connecting cable comprises a first section of which one part is held, in any position of the blade about the folding axis, above the mount and the radially outer end of the link member on which the mount pivots, in an off-centered position with respect to the folding axis and on the side towards which the blade is designed to be folded. This holding is provided by a cable support tied to the folding pivot and on which an arm, receiving the held part of this section of cable, is mounted in cantilever manner on the folding side.
Abstract: The present invention provides a convenient means for delivery personnel to deliver refrigerated goods to a building without having to wait until the building owner is home. The invention provides a dual-access insulated cabinet installable into the exterior wall of a home, with outside and inside doors. Both outside and inside doors contain lockable mechanisms for securing the doors. The insulated cabinet includes a main compartment for storing items to be frozen, an interior compartment for inserting into the wall of a building, and a cooling apparatus connected to the main compartment for selectively cooling the insulated cabinet to a selected temperature. An optional indicator light is inside whereby the light turns on when a delivery of refrigerated goods is made through the outside door of the invention. The indicator light then resets to the off state when the resident of the building opens the inside door of the present invention.
Abstract: A leg exercise device adapted for use with an adjustable dumbbell independent of a weight bench. The leg exercise device includes a bracket with a central sleeve that receives the bar of an adjustable dumbbell. Weight plates are attached to one end of the dumbbell bar and secured by a locking collar, while the other end of the bar receives a locking collar to secure the bar within the sleeve. A pair of opposing side portions extend out from the central sleeve and a foot handle is rotatable attached to each side portion. The foot handles include a pair of spaced outwardly extending padded fingers that engage opposite sides of the user's foot. The leg exercise device may be used to do leg extensions or leg curls on a weight bench that does not have an attachment designed for that purpose. The foot handles rotate while leg extensions or leg curls are being done so that the weight resistance automatically adjusts throughout the eccentric and concentric phases of each exercise.
