  • Publication number: 20100006491
    Abstract: The device for dehumidifying and compacting solids contained in sewage for disposal, is designed to be applicable to machinery (1) comprising: a tubular screen (2) having at least an inlet (4) for a product to be separated, at least an outlet (5) for a separated solid part, and at least a filtering wall (3) through which the separated liquid part exits; a transport organ (7) predisposed internally of the screen (2) for transporting the solid part to be compacted towards the outlet (5). The device comprises a contrast element (9), predisposed at the outlet (5) for interacting contactingly with the product, which in a rest position thereof occupies at least a part of a mouth of the outlet (5) and which, under an effect of a pushing action of the product to be compacted, can elastically deform in order to increase a size of a free mouth of the outlet.

  • Publication number: 20080309948
    Abstract: The process comprises a stage of highlighting a plurality of light points of a free surface of the material contained in the silo, of detecting a position of each of the light points and obtaining electrical signals which are proportional to the detected position of each point, and processing the signals to obtain a virtual reproduction of the free surface of the material which when processed provide desired data. The device for realising the process comprises lasers, which project a laser beam towards the free surface of the material contained in the silo, an optical sensor which detects the position of the light points defined by each laser beam on the free surface, and a data processing system which processes the data relating to the position of the lasers, the inclination of the laser beams, and the detected positions of the light points in such a way as to construct a virtual free surface of the material.

  • Publication number: 20050260538
    Abstract: The invention concerns equipment for extracting root post prosthetic elements or implants, such as an instrument including two lever assembled together by a pivoting and non-intersecting articulation, each of the levers having a handle and an extracting branch extending on either side of the articulation such that when the two handles are brought closer together, the two extracting branches are spaced apart. The ends of the extracting branches of the instruments are curved so as to form an angle with the remaining part of the branches. There are U-shaped extracting end pieces designed to be removably positioned and pivotably mounted, at the curved ends of the extracting branches.

  • Patent number: 6443040
    Abstract: A device for manufacturing a screw (2) comprises a cylindrical support (3) having a horizontal axis (x-13 x)and being rotatable there about. A straight bar (7) is wound spirally about the support (3). The bar (7) is constrained to a guide (8) and can perform movements in a parallel direction to the axis (x—x) of the support (3) on command of a translator provided with an endless screw (14). The process for manufacturing the screw comprises controlling axial movement of the guide (8) in a predetermined rapport with the rotation of the support (3). The invention is particularly applicable in the manufacture of a screw for a screw conveyor.

  • Patent number: 6322244
    Abstract: A mixer for mixing loose powder, granular and liquid materials includes a mixing chamber 8 having a rotatable shaft 4 therein. The shaft bears a plurality of radial blades for agitating the materials. Each of the radial blades 13 includes a wedge-shaped first part 14 and a second part 15 connected thereto. The first part includes a thin-edged front end 140 for penetrating the materials and the second part includes a frontal end 150 for impacting the materials. As a result, the mixer produces a high degree of homogenization with a relatively low degree of energy consumption.

  • Patent number: 6296106
    Abstract: A screw conveyor for loose material comprises a tubular casing having a first part which is axially rotatable on command with respect to a second part. The first part is provided with openings through which the material can be introduced into the casing. A screw, internal of and coaxial to the casing, can rotate on command about its own axis and thus convey the material. A helical conveyor device which is solid in rotation with said first part of the casing, conveys the material towards the openings in first part of the casing. There is a hollow jacket between the conveyor device and the second part of the casing, through which the material passes. The invention provides greater efficiency in collecting and removing loose material from a pile.

  • Patent number: 6044405
    Abstract: The method for electronically conveying large blocks of data between geographically-remote locations by uploading the sender's data to the local hub site of a service provider's network, earmarking that data with an electronic invoice, transmitting that data via the service provider's high speed network to a secondary hub site that is local to the recipient's geographic location, and downloading the data from the second hub site to the recipient's network. Duplicate archival versions of the transmitted data may be maintained at two geographically-distinct locations, such as the service provider's primary and secondary network hub sites. The total number of network connections may be reduced with a minimum number of alternative connections maintained to ensure data delivery in the event of a network connection failure. Value-added services may be performed on the data either prior or subsequent to its transmission between the primary and secondary hub sites.

  • Patent number: 4716066
    Abstract: A filling or packing body has an annular cell structure. All walls surrounding each cell are normal to the main plane along which the annular structure extends. Dividing walls between the cells transverse to an outer wall closed upon itself are parallel with each other at least for a row of adjacent cells or for all of them. The ring constituted by the row of cells having the outer wall in common can be of round, in particular of circular or elliptic configuration, or its configuration can be polygonal, especially triangular. The height of the cell walls, normal to the main plane, can be constant or it can be higher at the center than at the periphery of the ring structure.

  • Patent number: 4278384
    Abstract: Apparatus is disclosed for severing severable wrappers or packages containing granular or powder-like matter and for separating the matter from the severable packages. The apparatus comprises a helical screw, made of band-shaped foil wound helicoidally around a shaft, which rotates within a channel equipped with an open top load end where the packages to be torn are placed. The helical screw conveys both severed packages as well as the matter to a separating apparatus comprised of a rotatable housing made of screening and placed adjacent thereto to effect complete separation.
