A device for therapeutic treatment includes an acoustic transducer designed to emit power waves to treat a target, and an imaging probe designed to emit waves for providing an image representation of the target and its environment before, during and after the emission of the power waves issuing from the transducer. The probe and the transducer are integrally connected to one another other. The device also includes a display for displaying images taken by the probe, namely images at rest, taken before and/or after emission of the power waves, and interference images, taken during the emission of the power waves. The device additionally comprises a detector for detecting a change of structure of the interference images that is indicative of the efficacy of the power waves.

The present invention relates to functional footwear of a new concept, which adapts itself to the shape of a foot and gives a soft feeling when walking The footwear includes: an upper foot fixing section (1) for covering and fixing an upper portion of a foot; and a foot supporting section (8) attached to the upper foot fixing section for supporting a lower portion of the foot. The foot supporting section comprises a soft resilient mat (2) which can be deformed according to the shape of the foot. The footwear has a simple structure and can give a feeling of walking barefoot on a sponge mat or on a lawn like a extreme-soft-elastic carpet to provide complete comfort to the wearer during walking.

A luminescence concentrator (LK) may concentrate both incident direct and diffuse light by way of frequency shift and total internal reflection. It differs fundamentally from geometric concentrators. With sufficient geometric expansion of the collector plate, nearly arbitrarily high concentration can be achieved in the LK. A luminescence disperser is an apparatus which holds both directional and nondirectional incident light captive in a transparent body by way of frequency shift and total internal reflection and emits it diffusely or directionally uniformly distributed across an area by way of luminescence emission. The object of the invention is a method for the technical implementation of the LK and luminescence disperser, using zeolite crystals having a nanotube structure, into which the luminescent dyes are embedded such that they have antenna properties. Using the resulting novel structures, problems can be solved which made the technical use of LK impossible or at least considerably limited it. This results in completely novel usage possibilities for collecting and concentrating sun light and feeding it into photovoltaic systems, for converting it into electric and thermal energy in combined photovoltaic/hot water apparatuses, and for feeding it into fiber optic apparatuses.

The present invention relates to a method for the production of bodies in plastic comprising two portions hinged to each other by a single rotation pin. The method comprises the steps: a) predisposing a mold with two distinct forming chambers for the two portions; the mold comprises a third chamber for the single pin, made and positioned in such a way that the pin is formed already aligned along the hinge axis; the mold is provided with a pair of pegs axially distanced from each other to form the third chamber and sliding along the axis between a first and a second operating position; b) positioning the pegs in the first position; c) injecting plastic material inside the chambers; d) shifting the pegs from the first to the second position, bringing the pin to engage inside the seats; e) opening the mold and extracting the two assembled portions.

Granular material is dehumidified by: a) arranging a dehumidification plant having at least one hopper for containing the granular material, having a feed mouth and an output mouth, and at least one dry air generator fluidically connected to a dry air distributor inside the hopper; b) loading granular material into the hopper through the feed mouth; c) measuring the degree of initial humidity of the granular material entering the hopper; d) calculating on the basis of the values of initial humidity measured, the dehumidifying capacity of the dry air flow through the hopper needed to achieve predefined residual humidity values in the granular material leaving the hopper, the residence time of the granular material inside the hopper being fixed; e) generating a dry air flow through said hopper having a dehumidifying capacity calculated in the calculating step d).

A rotary valve position indicator utilizes a magnet keyed to a shaft, and a magnetic field sensor mounted beside the magnet, to indicate the angular position of the shaft. A magnetic pole sensor detects the initial polarity of the magnet during setup to determine how to correlate the output readings of the magnetic field sensor with the position of the valve. The sensors are located so they permit the shaft to extend through to a mechanical visual indicator.

The invention relates to a method for producing a semicrystalline polymer, said method comprising the following steps: producing a polymer melt from a crystallizable polymer; shaping particles and solidifying the polymer melt, the step of shaping the particles being carried out before or after solidification; cooling the particles; treating the particles to reduce their tendency to agglomerate; crystallizing the particles. The invention is characterized in that the treatment is carried out by shaking at a temperature T1 which is below the glass transition temperature of the polymer plus 10° C., i.e. T1

A sterilizable surgical accessory table includes a pair of independently movable tabletops supported by a base. The front tabletop is supported by a carriage which allows the position of the front tabletop to be adjusted fore and aft, while maintaining it in a horizontal plane. The rear tabletop cannot move fore and aft, but it can be tilted about a transverse horizontal axis. The rear tabletop is at all times well above the horizontal plane of the front tabletop. Both tabletops are normally locked in position, but the setting of each can be adjusted by depressing one of two pedals at the bottom of the base. The tabletops can be removed easily for cleaning and sterilization.
