Title: Automatic weld line following method
Inventor: IDE EIZO C O NAGASAKI TECHNICA
IPC: B23K9/02
Filed: 1983-10-17
Abstract: An automatic weld line following method for use with an arc welding method of welding a work by feeding a consumable electrode toward the weld line of the work through the tip of a welding torch and by oscillating the welding torch. The average and effective values of a welding current are detected, even if they are different, and fed to a computer so that the distance between the tip and the work is automatically controlled. At the same time, the oscillation angle is controlled to be symmetric at all times with respect of the weld line.

Abstract: Waste water having undergone anaerobic fermentation is treated by reduction of partial pressure of carbon dioxide (by reduction of the gas pressure above the surface of the waste water.or by stripping by carbon dioxide - free gas) in order to decompose calcium bicarbonate and precipitate calcium carbonate. The resulting water poor in calcium is used to dilute waste water rich in calcium before anaerobic fermentation.

Abstract: Apparatus is disclosed for automatically purging oil from the jets 91 supplying lubricant to a selected group of bearings and seals 90 in a turbine engine 10 subsequent to a shutdown. Purging prevents oil from coking as a result of heat soak back after the engine 10 stops. To accomplish this task, pressurized air is tapped from the air plenum 62 just downstream of the engine compressor stage 28,29. The pressurized air is stored in a small tank 72 using an air check valve 70 in the incoming line so that the air tank is charged to the highest pressure achieved by the engine compressor during its operation. At the outlet of the air tank there is connected one end of an air supply line whose second end is in communication with the oil jets 91 used for lubricating the selected group of engine bearings and seals 90 which are subject to being heated above 260°C (500°F) during heat soak back. A snap action valve 74 is inserted in the air supply line to activate and deactivate air flow out of the tank 72. Deactivation causes the snap action valve 74 to be switched "off" whenever there is positive oil pressure in the lubricating supply line leading 88 from the pressure pump 76 of the turbine engine. Subsequent to engine shutdown lubricant flow drops, reducing oil pressure to zero. This event coming subsequent to engine shutdown initiates the start of a delay interval after which the snap action valve 74 is activated to its "on" state allowing the contents of the air tank 72 to be blown through the oil jets 91, effectively clearing them of oil.

Abstract: The soap solution dispenser contains a reservoir into which opens an outlet or outflow opening of a container. In the reservoir there is present a float body or float which is pivotably mounted and provided with at least one indicator flag. Conjointly with the drop of the liquid level in the soap solution reservoir the float body also descends, which causes a displacement of the indicator flag. During the lowering of the surface of the soap solution the indicator flag moves along a viewing window formed in a cover or covering hood. There is thus signalled or indicated that the content of the soap solution in the reservoir is quite small or nearly consumed, so that the container now should be exchanged. One resulting advantage of the invention is that the indicator flag moves externally of the soap solution, so that the indicator flag cannot become stuck or bind, and thus, always remains readily visible.

Abstract: An integrated circuit device includes a timing apparatus arranged to produce timing signals whose frequency is a multiple of that of a clock signal. The timing apparatus, which includes a phase locked loop, is formed on a single chip and no external components are necessary. …<??>The phase locked loop includes a convertor and filter circuit (11), the convertor (14) including two transistor current sources (19, 24) whose current magnitude is determined by a current reference circuit (13) including current mirror transistors (28, 31). The current sources (19, 24) are controlled by increase and decrease output signals from a phase and frequency comparator (7) such that the output of the convertor (14) depends upon the mark space ratio of the comparator output signals. The output of the convertor (14) is filtered and then fed as the control voltage to a voltage controlled oscillator (12). The oscillator output is fed by way of a divider to the phase comparator (7) and also provides the high frequency input timing signal for a logic device, such as a microcomputer (2). …<??>As the timing apparatus is fabricated using MOS technology, it is not possible to forcast its performance accurately. Surprisingly, it has been found that the timing apparatus of the invention is capable of exhibiting closed loop stability without further trimming. However, to ensure that such closed loop stability can always be obtained, additional components, for varying the parameters of the circuits may be provided, said components being connectible into the circuit by programmable switches, such as laser fuses (as 33, 42).
