Abstract: Apparatus for the controlled withdrawal and delivery of volumetrically metered liquids of a type comprising a support structure able to receive a first series of vessels or bottles which contain substances in a liquid phase, and a second series of vessels or glasses able to receive one or more said substances in preset doses, means being provided for withdrawing and feeding said substances in preset doses and able to withdraw said substances individually from said bottles and discharge them into said glasses, apparatus characterized in that said withdrawal and delivery means comprise a series of single withdrawal and delivery members (7) able to be positioned in correspondence of each of said bottles and resolvably matchable with an actuation and driving head (6).

Abstract: An apparatus for dyeing textile materials is provided that includes one or more chambers for dyeing and one or more storage baskets. The apparatus has a first station with a container hydraulically connected with the chamber. The first station is for the drawing and metering of dyeing solutions and for the admission of the dyeing solutions into the container to feed the chamber for dyeing the material disposed inside the storage basket. A second station has a stirrer. The basket is connected in a stable but removable way to the stirrer. The basket is located in correspondence with the chamber.

Abstract: Apparatus for dyeing textile materials with a fixed, hollow and substantially cylindrical body intended to contain a dyeing bath consisting of water and dyeing substances in predetermined proportions, comprising in combination:--a basket for holding the materials to be dyed, whose side wall is provided with a plurality of ports or openings for the communication of the basket with the cavity of the body, and with upper and lower bases being provided with corresponding ports or openings, the basket being locatable within the cavity of the container and a transmission driven by a corresponding driving member and connected to the upper base of the basket for the vertical reciprocating movement thereof.

Abstract: An apparatus for the preparation of mixtures, especially dye solution. The apparatus includes a device for withdrawing a predetermined batch of product at a withdrawal station and for transferring the product to a separate dissolution station (SD). A device is provided for the dissolution of the product in the solvent, disposed in the dissolution station. A programmable electronic device is provided for operating the devices for withdrawal, transfer and dissolution of the product. The device for dissolution includes in a fixed horizontal plate with an annular seal housed in a corresponding channel of the lower surface of the plate making up a tight-sealing element for the mouth of a corresponding cylinder vessel containing the product to be dissolved. The vessel is associated with a vertical operating cylinder for driving the vessel from a lower to an upper position.

Abstract: Device for quickly variable and high precision metering of powder, granulated or micropearl dyeing material including a container 1 for the dyeing material that is put under vacuum by means of a suction tube 7 from the outside, and a mesh-sieve 5 fixed on the base of tile container 1. A scraper 2 rotates on the sieve 5 with a changeable speed. A scraper 2 rotates on the sieve 5 with a changeable speed. A compass-type shutter, with a changeable port, is mounted under the sieve 5, and a precision balance 20 is mounted below the shutter 6. An electronic computer 30 is programmed for checking and con trolling the rotation speed of the scraper 2, the opening/closing of the shutter 6 and the weight value of the balance 20.

Abstract: To continuously print polychromatic designs on fabrics, a method is provided for horizontally moving the fabric with predetermined speed and direction, for drawing a prearranged amount of different colored liquid dyes, for applying the dyes of several colors to areas corresponding to predetermined adjacent points of the fabric in such a manner as to obtain particular chromatic effects due to the contemporaneous combination of several colors. The device comprises means for representing, on a video monitor, the image of the pictorial effect to be reproduced.
