Title: Device for the regulation of the drive means in the winding of threads on textile machinery
Inventor: COLLI LUIGI
IPC: B65H54/42
Filed: 1987-10-19
Abstract: A device and a process for the regulation of the drive means which drive the various operating steps of the individual collection station of a winding machine, e.g., an automatic coner machine, wherein each collection station is equipped with a drive source. 
     More particularly, said device comprises: 
    - a three-phase motor driving the drive roll by means of a positive transmission, such as a toothed belt; 
    - a variable-frequency inverter, which feeds and pilots the drive source, in conformity with the signals coming from a central control unit, which in its turn processes the working parameters coming from the                                              winding station, together with the monitored data coming, in feedback, from the speed monitoring probe-wheel; 
    - a speed monitoring probe-wheel keyed on the drive shaft, capable of measuring the speed and the length of the thread being collected, according to preestablished sequences and operating cycles; 
    - a fully-reversible power circuit capable of making electric power flow both from the power supply distribution system to the drive source, and from this latter to the other drive sources of the operating front; or towards the same power supply distribution system.

Abstract: The carbonylation of an alcohol to produce a carboxylic acid, especially methanol to produce acetic acid, in a low water reaction medium containing a rhodium catalyst stabilized with an iodide salt, especially lithium iodide, along with alkyl iodide such as methyl iodide and alkyl acetate such as methyl acetate in specified proportions is improved by the addition of hydrogen in the feed gas to the low water reaction medium to obtain a reactor hydrogen partial pressure of at least about 4 psi. The presence of hydrogen in the reaction medium increases significantly the carbonylation reaction rate and reduced formation of byproduct carbon dioxide. The present reaction system not only provides an acid product of unusually low water content at unexpectedly favorable reaction rates but also, whether the water content is low or, as in the case of prior-art acetic acid technology, relatively high, is characterized by unexpectedly high catalyst stability; i.e., it is resistant to catalyst precipitation out of the reaction medium.

Abstract: The object of the present invention is a method and apparatus for treating medium consistency pulp in connection with diffe­rent treatment apparatuses, such as washers. 
     According to the prior art the treatment of pulp, for example, the washing process, begins at a low consistency, approximately 1 - 3 %. In other words it is always necessary to dilute pulp before washing, whereby the water consumption of the plant increases and the need of power in, for example, pumping and in the treatment generally increases. 
     With the method and apparatus of the invention it is possible to treat medium consistency pulp (8 to 20%), because the feeding appa­ratus (20, 30, 40) is able to spread the pulp as an even web on the treating apparatus 1.

Abstract: A breathing circuit connector (31) for intercoupling between the flexible hoses of an anaesthesia machine and the input connector of an endotracheal tube comprises a hollow body of relatively rigid material having a cylindrical male input section (32) and a cylindrical female output section (36). A cylindrical bore (40) within the hollow body extends between the cylindrical input (32) and output sections (36). The bore within the cylindrical output (36) section consists of a series of two or more cylindrical portions (37,38,39) having different internal diameters. The internal diameter of the first bore portion (37) adjacent the output end of the cylindrical output section (36) is slightly larger than the internal diameter of the bore portion situated within the cylindrical output section. The breathing circuit connector may be formed as an elbow with the longtiduinal axis of the bore of the cylindrical output section being inclined relative to the longitudinal axis of the bore of the cylindrical input section. Alternatively, the improved connector may comprise a single female output section and a pair of cylindrical male sections, each section having a bore whose axis is displaced from the other two to form a Y-shaped connector.

Abstract: This invention relates to a Bi-MOS semiconductor device forming a bipolar circuit and a MOS circuit on a single silicon substrate, in which a buried layer is formed beneath the epitaxial layer composing the MOS circuit, and this buried layer is connected to a power supply having a higher or lower potential than the potential of the silicon substrate and a low impedance. In this constitution, the buried layer can function as an equivalent earth shield. Accordingly, the mutual interference between the diffusion region of the MOSFET and the buried layer formed beneath the epitaxial layer for the bipolar circuit is lessened, and high frequency leak current can hardly flow. As a result, the chip size can be shrinked without adversely affecting the circuit characteristics.
