A process for producing a diaphragm for a speaker of carbonaceous materials which includes the steps of mixing carbon powder in a binder mainly containing chlorine-containing vinyl resin to be carbonized after calcining, applying high shearing force to a mixture composition obtained by uniformly mixing and dispersing the resultant mixture to sufficiently knead the mixture, then preliminarily moldi...

The present invention relates to a remote actuator for a piece of equipment, operating by variation in the flow conditions of a possibly incompressible fluid, comprising an actuating piston (12) and a nozzle-needle unit (20, 21; 53, 57). This actuator is characterised in that one of these two elements (20, 21; 53, 57) is mounted so as to slide in the said piston (12), and in that it comprises mean...

The subject of the present invention is an extensometer sensor (1, 1') for measuring stresses by means of gauges acting on a drilling element (50) at the bottom of a well. The extensometer sensor comprises: - a first measuring zone (10) composed of at least two tension leaves (11, 12, 13), on which are mounted measuring gauges connected at their ends by means of vertical members (14, 15), so...

Apparatus for cutting up carcasses in an abattoir, and in particular for cleaving them in two, comprises: a support beam securely mounted on a cleaving carriage via a pivot mount enabling the beam to pivot angularly about a pivot axis extending parallel to the cleaving direction; and adjustment means interposed between the cleaving carriage and the support beam to adjust the angular position of th...

A method of making an integrally molded composite article composed of a ring-opened polynorbornene matrix and a compatibilized laminate and/or core components is disclosed. Laminate and/or core components that have low adhesion to polynorbornene or that interfere with the ringopening polymerization of norbornene monomers are compatibilized by coating at least a portion of their surface with an ine...

The cleaning apparatus is formed by a housing member adapted to be inserted into an air duct and which has two spaced apart ports for providing an air flow path through the housing member. A flexible hose has one end coupled to one of the ports and is employed for moving the housing member in the air duct and for providing a passage for the flow of air from or to the housing member. A turbine form...

In order to enhance the contrast of an image, especially of a radiology image, the dynamic range of which is occupied by large structures to the detriment of the contrast accorded to small structures, filtering of the image to be processed is performed in order to produce a defocused mask therefrom. The defocused mask reveals the large structures of the image. Next, in a linear combination, the de...
