Abstract: The invention concerns a process and a device for avoiding interruptions of operation caused by the strapping, on machines for the strapping of packing elements. The process is characterized by a second strapping coil with further strapping, and in that the leader of one of the two strappings is constantly kept at a standby position in the machine from which, upon removal of the other strapping from the strapping guideway, it is automatically fed to the strapping guideway. The device is characterized in that the feed system is preceded by a switch with two strapping guideways for a leader section for each one of the two strappings, with a strapping feed for the alternative introduction of one of the two strapping leaders into the feed system. A first drive system is provided within the vicinity of the strapping guideways for selectively introducing one of the strapping materials into the feed system, while a second drive system is provided within the vicinity of the supply coils of the strapping materials for selectively engaging one of the supply coils in order to retract or withdraw a damaged or depleted strapping material from the feed system and permit a second one of the strapping materials to be introduced into the feed system.

Abstract: The air conditioner consists of indoor unit having remote receiver(1), detecting means of indoor temperature and humidity(2), detecting means of piping temperature(3), micom for indoor unit(4), driving means of indoor fan(5), driving means of wind direction louver(6), control means of power relay(7), detecting means of outdoor piping temperature(9), micom for outdoor unit(10), driving means of outdoor fan(11), control means of compressor(12), and detecting means of temperature for compressor(13). The signal about the operation of air condition is received to the remote receiver(1). The received signal is estimated that the signal is the operating on signal or the operation off signal. When the operating signal is turned on, the relay permitting the power to the outdoor unit is turned on. Then the air conditioner is normally operated. The power of outdoor unit is turned off when the condition is not the operating-on. When the relay is off, the condition of heating is judged. If the condition of heating is not, the power of outdoor unit is interrupted, and if the condition is prepared, the off-time is counted. As the counted off-time is longer than the given time, the counted time is reset so as to permit the power to outdoor unit. The temperature of compressor by the relay-on driving is detected. If the detected temperature of compressor is below the given temperature, the temperature of compressor is raised. The raised temperature is higher than the given temperature, the power of outdoor unit is interrupted, the temperature and standby status are continued.

The safety valve also included a bracket(21) having a circular hole to seceive the head(2) of valve(1) to play the hole, the valve sheat(10) beinging joined with bracket(21), and having a spring(14) to urge the valve head(2). When the pressure(P1) of the upstream is higher than the pressure(P2) of the downstream, the valve(1) moves to the tin of cylinder(11) of valve sheat(10) to open the hole with the pushed spring(14). When P1 and P2 come near to equilibrium, the valve(1) returns to the original position by the spring(14).

Title: Passive type pressurized light water reactor
Inventor: NOH HEE-CHUN
IPC: G21C15/18
Filed: 1993-09-25
Granted: 1997-12-30
Abstract: Furnace center supplementary water tank of the passive type pressure light water furnace, whereby the device is installed in the steam entrance in order to prevent the excessive condensation of the upper of the tank. The end part of the pressure device balance valve that connects with the pressure device, provides to pass through the inner of the furnace center supplementary water tank because of connecting the end part of the valve with the upper of the tank.
