Abstract: ABSTRACT OF THE DISCLOSURE:     A method of controlling the web tension of a web roll, in particular a paper web roll, which roll is being wound in a winder including two individually driven web roll supporting rollers. Separate signals representative of the speed of rotation of each driven supporting roller are derived, and the speed of rotation of each driven supporting roller is controlled in dependence on a dif-ference between these signals, to thereby control the web tension of the web roll. The method includes measuring a number of turns and a length of web wound during a measuring period, signals resulting from these measurements being supplied with information about a surface weight of the web to a device for computing a density signal for the portion of the web roll formed during the measuring period. Such a density signal is used as a superordinate control signal for controlling the web tension of the web roll.

Granted: 1986-06-10
Abstract: - 21 -ABSTRACT OF THE DISCLOSURE The spray valve comprises a cylindrical component hav-ing a central passage, which body is slidingly disposed in a widened portion of the valve body. The cross-sectional area of the central passage is smaller than that of the widened portion, so that the cylindrical component is displaced outwardly against the return force of a spring by the flow occuring when the spray valve is opened. A permanent magnet is embedded in the wall of the cylindrical component. In the wall of the valve body surrounding the widened portion thereof there is a blind bore in which a reed contact is inserted. Through the flow of liquid occuring when the spray valve is opened, the magnet is displaced into the field of response of the reed contact, which thus indicates the opening of the spray valve. This spary valve is intended to be utilized in a system for spraying a thawing agent. A plurality of control circuits are disposed along a roadway, one of the spray valves being associated with each control circuit. The reed contacts make possible a remote indication of the operating readiness of the individual spray valves, making the spraying system much more reliable.

The contact supports are interchangeable and are made of a nonconductive molded plastic.  The contact supports are adapted to selectively support either conductive contact support bars on which relatively stationary spring contacts are mounted, or contact blades which, in association with movement of a movable contact support, may be closed into spring contacts carried on an associated relatively fixed contact support.  The movable contact blades comprise flexible braided electrical conductors having conductive contact sleeves swaged on their opposite ends so that the contact end portions define contact bars which are substantially solid in transverse cross section.  In a two position embodiment, the contact bar ends of each contact blade are adapted, respectively, for fixed connection to the bushing connectors of service entrance terminals and for movement into closed circuit with corresponding spring contacts mounted on the fixed contact support.  In a three-position embodiment, a third molded contact support is fixed within the casing and has similar contacts associated therewith to enable closed circuit connection of alternative service entrance terminals.

Abstract: Abstract of the Disclosure:     In a loop network system comprising a plurality of stations connected by a loop-shaped transmission path (38), a particular one (30) of the stations transmits, to the path at a predetermined period, a synchronization signal block serving to trigger the other stations (31-36) and to define a highest degree of priority for transmission.  A trigger signal block is also transmitted from the particular station to the path so as to define a lower degree of priority each time when a transmission right is seized by the particular station within the predetermined period.  Each of the other stations transmits a transmission signal block to the path by seizing a transmission right in consideration of the degree of priority indicated by each of the synchronization and the trigger signal blocks.  Each transmission right is given to each station when no signal block is present on the path.          A pair of token blocks may be used to guarantee communication of the highest degree of priority and another communication of the lower degree in the predetermined period.     [Fig. 1]

Abstract: ABSTRACT     Methods are provided for selectively placing a barrier to fluid flow within water rich strata or played out strata of a subterranean formation, thebarrier being established at some distance remote from a wellbore.  The methods involve first washing a desired volume of forma-tion with an acid solution suchas HCl.  The acid solution is effective to extract and remove polyvalent metal ions from the formation material.  Next an acidified resin emulsion composition comprising an oil soluble, acid stable resin is injected into the formation.  The resin emulsion traverses the washed region without plugging. When the resin reaches the outer edge of the washed region the acidified emulsion extracts metal ions adsorbed to the unwashed formation material.  The extracted polyvalent metal ions are effective to demulsify and coalesce the resin, thereby establishing a relatively impermeable barrier to subsequent fluid flow.      The methods of this invention have application in a wide variety of profile control techniques for effecting conformance or sweep efficiency in oil bearing subterra-nean formations.
