IPC: H04J3/16
Filed: 1990-09-26
Abstract: A frame organized time division multiplex communication system includes a central office and at least one remote terminal. A time division linkconnected between each remote terminal and the central office carries signals organized in time division multiplex frames. The central office determines the time division multiplex link frame format. Each remote terminal has at least one interface connected to the time division link that multiplexes signals into the time division multiplex frames, demultiplexes signals from the time division multiplex frames and monitors the time division frames from the time division link for in-frame and out-of-frame operation. An interface controller in the remote terminal determines the frame configuration of the interface multiplexing and demultiplexing. The controller identifies interfaces exhibiting out-of-frame operation and automatically switches the identified out-of-frame interfaces to an alternate frame configuration. The remote terminal frame configuration is thereby adjusted to correspond to a change in time division link frame format.

Abstract: Abstract of the Disclosure A paste-like composition containing a lead salt of an organic acid and tin powder is applied on a pad array portion of a citcuit board.  Then, the paste-like compo-sition is heated so as to cause precipitation, thereby forming a solder layer formed of an Sn-Pb alloy substan-tially only on pads.  This precipitation is performed in a state that a liquid pool is formed on the pad array portion when the paste-like composition is liquified by heating, and the tin powder is settled in the liquid pool.  When an electronic part is to be mounted on the pads, first, preparatory solder layers are formed on the pads by the above-mentioned precipitation process. After a paste-like composition is applied on the prepar-atory solder layers, the electronic part is put on the paste-like composition.  Then, the paste-liks composi-tion is heated, thereby soldering leads of the elec-tronic part with the pads.

Abstract: Melt processable copolymers of vinylidene fluoride and hexafluoropropylene, containing from about 1% to about 20% hexafluoropropylene by weight, are prepared by emulsion polymerization of vinylidene fluoride and hexafluoropropylene in a stirred aqueous reaction medium.  The reaction medium is formed by charging to a heated reactor, water, vinylidene fluoride, an initiator to start the polymerization, and a water-soluble surfactant capable of emulsifying both the initiator and the reaction mass during polymerization. Additional  amounts of  vinylidene  fluoride  and initiator  are  fed  to  the  reaction  medium  to  continue polymerization of the vinylidene  fluoride monomer until from abut 50%  to abut  90%  of the total weight of the vinylidene fluoride monomer utilized in the process has been added to the reaction medium.  There is then added to the reaction medium (i)  from about 1% to about 20% hexafluoropropylene by weight, based upon the combined weight of the hexafluoropropylene and the total weight of the vinylidene fluoride utilized in the process, and (ii) the balance of the vinylidene fluoride utilized in the process. The resulting vinylidene fluoride/hexafluoropropylene copolymers are characterized by improved mechanical properties and a DSC melting point typically in the range of from about 160°C to about 170°C, preferably from about 163°C to about 168°C.

Title: Deflection-compensated doctor blade beam
Inventor: ESKELINEN JUHANI
IPC: D21G3/00
Filed: 1991-12-10
Abstract: The present invention concerns a deflection-compensated doctor blade beam of a coater used for coating web materials. The doctor blade beam comprises a box-section frame (3), together with a holder 2) of the doctor blade, and a support tube (4) placed to the interior of the frame (3). The support tube (4) is backed against the frame (3) by means of three asymmetrically placed compensating elements (5), which advantageously are pressurized hoses. The deflection of the doctor blade beam is compensated for by varying the volume of the compensating elements (5) through pressure alterations in the elements.      A displacement of desired direction can be achieved by means of three compensating elements (5) in the plane of the blade beam's cross section. By virtue of the achieved displacement, the deflection of the doctor blade can be compensated to full straightness. The compensating system is controlled with the help of a feedback loop using data from a direct measurement of beam deflection, or alternatively, from the coat thickness profile. The straightness of the beam can be controlled on the basis of measurement data either automatically or manually.

Abstract: A rheometer or viscometer for continuously measuring the rheological properties of non-Newtonian, mixed phase fluids or slurries.    The device has a vertically disposed, inverted U-tube to maintain solids in suspension and, therefore, exhibit a homogeneous character. The fluid flow rate is controlled to assure nonturbulent laminar flow through the tube.    Pressure is measured at a point in each leg of the U-tube and compared. For a constant flow rate, the pressure drop over the tube is used to measure the viscosity of the fluid in the tube.
