摘要:
The present invention is related to a radiation curable binder, comprising the reaction product of a polyisocyanate having 3 free isocyanate moieties with an acrylate having isocyanate-reactive groups and a component selected from the group consisting of a C12-C22 carboxylic acid having one isocyanate-reactive group or a C12-C22 fatty alcohol. The present invention is furthermore related to a radiation curable printing ink, comprising said binder, at least one diluent, at least one pigment, and optionally additives, as well as to a process of preparing said radiation curable binder. Said binder or said printing ink can be used in offset printing or letterpress printing.

The present invention refers to a combined process for generating steam in a steam-baking oven. The oven (2) comprises a baking chamber (3) containing at least one air heating element (10) and at least one fan (4) to keep the air moving inside the baking chamber (3); the oven (2) is associated with a steam generator (5) and is connected to a water supply (6). The combined process includes a saturation step, in which the steam generator (5) is activated until a substantial steam saturation is obtained in the baking chamber (3), and a spraying step in which the steam generator (5) is deactivated and the steam is produced by spraying water onto the heating elements (10); the steam generator (5) is temporarily and periodically activated during the spraying step to keep the steam quality substantially constant.

A ring derrick includes a carriage which moves on a fixed circular track around a stationary counterweight. A tension and compression column assembled from transportable tubular segments is affixed to the counterweight by a universal swivel joint. The back mast of the derrick is secured at its upper end to the tension column, while the main boom of the derrick extends radially away from the tension column. The main boom and back mast are hinged directly together at the carriage by massive hinge pins which pass through spherical bearings mounted on the carriage. The carriage's suspension distributes the load from the boom and mast to an array of trucks and has an automatic stabilizing system that compensates for uneven track.

The invention deals with an aid device for reading a printed text, comprising a data acquisition peripheral with a camera and a communication interface, said peripheral being movable by a user on a printed text to frame a portion of text, a processing unit, communication means between the peripheral and the processing unit, and a vocal reproduction device. The processing unit is programmed to acquire a sequence of images framed by the camera, to detect when the user has stopped on the text, to recognize at least one word which the user intends reading, and to reproduce the sound of said at least one word by means of vocal synthesis by means of the vocal reproduction device.

A grinding device includes a mobile grinder group having openings for dispensing a ground product and a fixed counter-grinder having a central hole the surface of which comprises a grinding surface. The grinder group has a casing and a grinder which can be fixedly coupled, the grinder having a grinding surface that is inserted inside the central hole of the counter-grinder and that cooperates with the opposing grinding surface of the counter-grinder when grinding a product. The grinder group is arranged straddling the counter-grinder with the casing being arranged outside the counter-grinder. The casing can rotate with respect to the counter-grinder and is axially mobile with respect to the counter-grinder between two or more reciprocal adjustment positions. The grinder and the counter-grinder are made in a substantially rigid material and the casing is made from a substantially flexible material.

A securing cap, for use in fixing a wall with a floor or ceiling mounting, is snap fit within the space between the wall and a floor or ceiling mounting thereby fixing each component in position. The securing cap, in conjunction with other such caps, holds a wall assembly in a desired position in a building or shed where wall panels are positioned relative to each other to form a wall. The securing cap also serves to prevent the accumulation of dust and debris within the space formed by the wall and the floor or ceiling mountings.
摘要:
Granular material is dehumidified by: a) providing a number of dry air generators inside hoppers containing granular material; b) for each dry air generator, evaluating the dry air flow generable and/or higher energy efficiency functioning time; c) calculating the dry air flow rate for each single hopper depending on the characteristics of the granular material; and d) activating a number of generators sufficient to deliver a total dry air flow rate equal to the sum of the flow rates required by the hoppers. The number of the generators and the generators to be activated are chosen depending on the flow rate deliverable by each and/or by their respective ranges of functioning at higher energy efficiency according to an energy saving logic. The remaining generators are deactivated.
