Patent EP-0648569-A1 (EP)
Inventor: HIDEKI IKEGAMI C O DENYO KABUS
IPC: B23K9/10
Filed: 1994-10-15
Abstract: There is provided an engine driven arc welder adapted for converting a.c. output of welding generator into d.c. output to allow it to undergo switching control by using a switching circuit to detect an output of the switching circuit to control its ON/OFF period by the detected content to control a welding current. This engine driven arc welder further comprises a reference signal formation circuit for forming a reference signal such that when a detected voltage across welding terminals is higher than a first predetermined value, it has a first reference value, when that detected voltage is lower than a second predetermined value, it has a second reference value higher than the first reference value, and when that detected voltage is between the first and second predetermined values, it has a reference value of drooping characteristic continuously connecting the first and second reference values, thus to compare a detected signal at the welding terminal with the reference signal of the reference signal formation circuit to control the switching circuit. Further, this invention can be applied to an engine driven arc welder with load limiting function. In this case, AVR is employed in a feedback control loop for generator voltage. The circuit configuration includes a F/V characteristic circuit and an output suppression circuit for comparing a detected voltage of the welding generator with a predetermined reference voltage to deliver, when the detected voltage is lower than the reference voltage, a signal for suppressing a welding output to a constant current control circuit for controlling welding current so that it becomes equal to a fixed value.

Abstract: Disclosed is a method for the transmission of line-oriented data sets. This method employs two data set structures which keep the images of the data sets at different time stages and which are filled alternatingly with the data sets. The method allows to determine updates of the data sets and avoids re-transmission of old information. In particular, moved lines are detected in a very effective manner. As a result, high update rates with low amounts of transmitted data are achieved. 
     The method is suitable for local terminal sessions employing text or raster graphic terminals, which have to be operated from a remote site.

Abstract: An unacceptable coin removing apparatus for a coin handling machine includes a rotatable disk (1) for receiving coins (c) deposited into the coin handling machine and feeding coins one by one into a coin passage (2) provided with a reference guide rail (3) and a guide rail (4) facing the reference guide rail (3), transporting belts (8,9) for transporting coins (c) in the coin passage (2), sensors (5,11) for detecting coins (c), a first projecting member (17) which can be projected from the reference guide rail (3) into the coin passage (2), a second projecting member (20) which can be projected from the guide rail (4) into the coin passage (2), a coin collecting opening (10) and a controller (40) for controlling the operation of the first projecting member (17), the second projecting member (20), the transporting belts (8,9) and the rotatable disk (1). When the sensors (5,11) detect an acceptable coin (c), the controller (40) does not actuate the first (17) and second (20) projecting members. When the sensors (5,11) detect an unacceptable coin (c) or a foreign article, the controller (40) projects the first or second projecting member (17,20), thereby leading the coin (c) to the coin collecting opening (10) and removing it. When it is unclear whether or not a coin (c) is acceptable, the controller (40) projects the first and second projecting members (17,20), reversely drives the transporting belts (8,9) and the rotatable disk (1) so as to return the coin (c) onto the rotatable disk (1) and then repeats the above described operation until it becomes clear whether or not the coin (c) is acceptable. According to the unacceptable coin (c) removing apparatus, unacceptable coins (c) or foreign articles can be efficiently and reliably removed.

Abstract: The invention describes a roller bearing (1) having an extended operational life, whereby the bearing comprises a seal (4), which seal (4) is provided with lubricating grease retaining means. These lubricant-retaining means (12) can have a variety of forms and they prevent lubricating grease from coming into contact with the rotating bodies or the races of the bearing (1), for instance due to vibration, during operation of the bearing. Thus sharp rises in temperature and loss of lubricating grease are avoided, which would shorten the operational life of the bearing. Preferably the bearing (1) comprises a seal of which the means for the retention of the lubricant are formed of plastic. The invention also relates to a seal provided with means for the retention of lubricant.

Filed: 1994-11-15
Abstract: The present invention relates to a device making it possible, in the event of an accident, to open or to close a gate valve (1) the gate (3) of which moves in translation and is usually activated by a motor (6). The device according to the invention comprises a linkage system (7) including an enclosure (8) containing a ring (19) clamped tightly around the ends (20 and 21) of the operating shaft (4) and of the driveshaft (5). In normal operation a shear pin (22) secures the ring to the shafts (4, 5). In the event of the motor being unobtainable, under the action of the pressure of a fluid introduced via an orifice (30), the pin (22) breaks and the ring comes to bear on a stop (29) situated below the said ring and borne by the operating shaft (4) of the gate valve in order to act as a piston and close the gate (3) thereof. When the ring is not clamped directly around the ends of the two shafts, but the latter, penetrating one another, are clamped together in a connecting assembly supported by the said ring and when the operating shaft has a second stop situated above the ring, it is also possible to open the gate when the motor is unavailable. The device according to the invention makes it possible to retain use of the motor (6) under normal circumstances. <IMAGE>
