Patent EP-0357045-A2 (EP)
Title: A process for preparing polyarylene sulfides
Inventor: SENGA MINORU IDEMITSU PETROCHE
IPC: C08G75/0222
Filed: 1989-08-30
Abstract: Polyarylene sulfides are prepared by reacting a dihalogen aromatic compound with a sodium hydrosulfide in the presence of an alkali metal aminoalkanoate and a lithium halide in an organic polar solvent. This process can prevent a decomposition of the sodium hydrosulfide during dehydration and produce the polyarylene sulfides in a granular form in high yields and with high efficiency. 
     The polyarylene sulfides obtainable by this process are high in molecular weight and degree of whiteness and low in a content of salts remaining therein. Furthermore, the polyarylene sulfides are in the granular form so that they can be handled with ease because of their readily separability and washability.

Abstract: Apparatus for monitoring the cloud point of a liquid, or the temperature at which any light scattering phase occurs therein, comprising a light-proof and light-absorbing chamber, and a liquid sample-receiving receptacle within the chamber having a bottom formed by a non-light-scattering surface; this surface being in thermal contact with a heating or cooling device, such as a thermoelectric cooler, and with a temperature measurement device. The chamber allows access to the receptacle so that sample liquid can be placed therein. A light beam source is located to direct a beam of light onto the surface at an incident angle so that light from the beam is reflected or absorbed by the surface. A light detector is arranged so as to detect scattered light which is produced when solid material forms in the liquid as it is cooled or disappears on heating. The melting point of a solid, or the boiling point of a liquid, can be detected, in addition to cloud points.

Abstract: An inference processor includes a production rule memory (11), a meta knowledge generator (12), a meta knowledge memory (13), a production system interpreter (14), and a working memory (15). The meta knowledge generator (12) obtains production rules satisfying transition conditions between all the combinations of the states of the respective variables in the production rules as a directed-graph matrix. The meta knowledge generator then decomposes the directed-graph matrix into strongly connected components, and obtains, as meta knowledge, 1) variable-conditions of the respective strongly-connected components and 2) productions rules satisfying transition conditions between the respective strongly-connected components. The interpreter (14) generally determines an inference path from a given state to another state as a target on the basis of the meta knowledge, and efficiently executes production rules, thereby performing inference processing.

A space above the second area is enlarged when the stacker is brought to the rest position, whereby the ink ribbon cassette disposed beneath the second area can easily be exchanged. When the continuous sheet is used, the stacker is brought to the rest position allowing to receive the continuous sheet from the platen. A sheet feed direction switching unit is detachably coupled to the stacker for selectively discharging the printed cut sheet onto a sub-­stacker face up or onto the stacker face down.

Abstract: Process for bending a sheet of glass, especially of a motor vehicle glazing, with a bent zone, according to a small radius of curvature. The bending tool employed is a press composed of a female mould (18) and a male mould (12), the female mould consisting of at least two members (29, 30) connected together and articulated. After the bending press has taken hold of a part of the glass sheet (2) heated to the bending temperature, at least one of the articulated members (30, 30') of the mould (18) is bent back against the male mould (12) around the articulation axis. A controllable constant-torque motor (38) is used for controlling the movement of the articulated members whose angular velocity is controlled during the bending process as a function of the temperature of the sheet (2') and of the degree of deformation. …<IMAGE>…

Abstract: In a method for controlling the armature movement of a switching magnet, in particular of electromagnets for actuators of internal-combustion engines, it is intended to reduce considerably the energy and material consumption. This is achieved in that the coil current of the electromagnet is linearly regulated before the expected impact of the magnetic armature on the pole surface. The impact of the magnetic armature on the pole surface of the electromagnet preferably occurs in this case during the linear regulation. <IMAGE>

Abstract: A pacemaker for terminating a cardiac arrhythmia stimulates the heart with at least one stimulation pulse (42) during a narrow region of susceptibility (46) of the arrhythmia cycle. The location of the region of susceptibility (46) is initially found by delivering the stimulation pulse(s) (42) to the heart in accordance with a prescribed scan pattern. When the arrhythmia is successfully terminated, the location (o) of the successful stimulation pulse (42) within the prescribed scan pattern is stored. Upon the next occurrence of a cardiac arrhythmia, the initial stimulation pulse (42) is presented to the heart at a time (k) within the prescribed scan pattern that is backed up from the location (o) of the prior successful stimulation pulse (42) by a prescribed amount. Thus, even though the region of susceptibility (46) may have moved in either direction within the cardiac cycle, the initial stimulation pulse (42) of the next scanning sequence is likely to be applied at a location within the cardiac cycle that is near and moving towards the region of susceptibility (46).
