Patent EP-0425708-A1 (EP)
Inventor: ISHII HIROMITSU
IPC: B01J19/20
Filed: 1990-05-17
Abstract: An elastic polyester is continuously produced by continuously feeding an aromatic polyester and a lactone to an extruder (6), which is provided with a cylinder having an aspect ratio (L/D) ranging from 3 to 50 (wherein L represents the cylinder length of a reactor and D the inner diameter of the cylinder) and at least one screw and wherein the space in the cylinder provided with the screw accounts for 70% or less of the internal volume of the cylinder, and reacting the lactone with the aromatic polyester while conducting the melting, carrying and kneading of the feed material in the extruder (6). Since the screw can be turned with a high speed, the effect of kneading can be enhanced and the reaction time can be shortened. Since the obtained elastic polyester is excellent in durability represented by thermal and weathering resistances, rubber elasticity, and mechanical properties, it has a wide range of uses such as automotive parts, electric and electronics components and machine parts.

Abstract: The bush comprises a core (1) surrounded by a casing (5), a relative axial displacement of these components serving for modifying the inside diameter of the core by means of a clamping obtained by the reciprocal action of two complementary conical surfaces (4, 8) provided on these components. These are mounted in a housing (7) by means of two sets of bearings (6, 27), allowing them to rotate independently. One of the sets is mounted in a piston (15) controlled hydraulically or pneumatically (16, 17, 18, 19) in order to modify its axial distance from the other. This makes it possible by a variation of pressure to modify the depth of engagement of the casing on the core and therefore the inside diameter of the latter, even when these components are rotating. <IMAGE>

Abstract: The method consists of measuring the electrical resistance of the electrode separation (which is formed by a tool electrode and a workpiece electrode from metal or an alloy which is to be processed) in the pauses between constant discharge pulse groups and the voltage between the tool electrode and the workpiece electrode at the time of the discharge, and of controlling the discharge current and the electrode separation on the basis of the measurement results, in the event of the electrical resistance being reduced to a specific critical constant (which corresponds to the concentration of the discharge pulses on a local section of the processing zone), the above-mentioned pauses between the discharge pulse groups and the separation between the tool electrode and workpiece electrode being increased (without interrupting the process) up to a value as a result of which the electrical resistance of the electrode separation is increased; the fast reverse movements of the tool electrode are activated in such a manner that the length of the return movement is proportional to the frequency of occurrence and the duration of the existence of the above-mentioned critical value of the electrical resistance of the electrode separation; in the case when the level and/or the shape of the voltage between the tool electrode and workpiece electrode become abnormal in the first half of the discharge time, the discharge current is switched off until the start of the following pulse. The invention is expediently used for increasing the productivity of the eroding process and the processing accuracy of the workpiece, and in order to remedy damage to workpieces having a complex profile and parts consisting of current-conducting materials which are difficult to process.

The starter circuit includes a battery, one electrode of which is connected to one terminal of a smoothing capacitor (CD) connected between the DC terminals of the inverter transformation circuit in such a manner that the electrode and the terminal are of the same polarity. The other electrode is connected to one of the output terminals of an AC generator system through a switch (SW) which is closed to start the engine, and which is connected to a reactor forming an LC circuit. In starting the engine, the rectifier circuit (1) is driven in an inverter transformation mode, one of the switching elements (QI4) in the inverter transformation circuit which is connected between the reactor and the one terminal of the smoothing capacitor being driven in a chopper mode. The inverter transformation circuit is formed by bridge-connecting switching elements each having a flywheel diode. The same starting circuit may be used in connection with a DC generator, with or without the inclusion of a smoothing capacitor at the output of the DC generator.
