Patent number: 5704405Abstract: For metering of heavy gas which is intended for use in filling insulating glass panes with heavy gas or in the assembly of heavy gas-filled insulating glass panes, heavy gas is introduced into A space (5) of a cylinder (1) whose internal space is divided by a piston (2) into two spaces (5 and 6), piston (2) moving as other space (6) becomes smaller, so that heavy gas flows out of the latter. The displacement path of piston (2) is measured by displacement sensor (7) and electronic rule (4). Furthermore, the temperature and pressure of the heavy gas flowing out of space (6) via connection (20) are measured and the displacement of piston (2) is interrupted as soon as the amount of heavy gas determined on the basis of the displacement path and the values of temperature and pressure of the discharging heavy gas corresponds to the required amount of heavy gas.Type: GrantFiled: March 21, 1996Date of Patent: January 6, 1998Inventor: Peter Lisec

Patent number: 5697990Abstract: A hardened asbestos-free, porous, calcium silicate filler material for an acetylene storage vessel is made by mixing quicklime with water to form a first mixture. Then ground quartz silica is added to form a second mixture. A fibrous reinforcing material is blended in to form a third mixture. A precipitated silica (or synthetic silica) is added and homogenized to form a fourth mixture. The fourth mixture is transferred into a cylinder to be filled and is cured under saturated steam pressure. Thereafter, the cylinder is dried. A gas storage cylinder so formed has a monolithic dry mass filling a metal shell. The mass has a porosity of about 88 to 92%, a density in the range of 250 g/l to 350 g/l, and a crush strength of 250 to 550 psig.Type: GrantFiled: December 11, 1995Date of Patent: December 16, 1997Assignee: Worthington Acetylene Cylinder, Inc.Inventors: Gregory T.

Patent number: 5676782Abstract: To produce insulating glass panes (10) filled with heavy gas, an insulating glass pane (10) still open at least in the area of its lower edge is filled from underneath with heavy gas. To do this the two vertically oriented edges of the insulating glass pane (10) are sealed by seals (30, 31). The upper edge of the insulating glass pane is not sealed. At at least one site (156, 157) in the area of the lower edge, the heavy gas from a channel (122) which runs along a belt conveyor (9) which supports the insulating glass pane (10) is blown via openings which pass between side-by-side portions of the conveyor belt of the belt conveyor (9), into the insulating glass pane (10). To adjust the effective length of the channel (122) to the length of the insulating glass pane (10) to be filled with heavy gas, a piston (130) is contained in the channel. As soon as the space between the glass sheets (11, 13) of an insulating glass pane (10) is entirely filled with heavy gas, the insulating glass pane (10) is closed.Type: GrantFiled: March 24, 1995Date of Patent: October 14, 1997Inventor: Peter Lisec

Patent number: 5655578Abstract: The invention described in the patent is an automatic control system which provides monitoring, supervision, and control of the process of filling of a tank or container with a liquid, where at the temperature of operation the vapor pressure of the liquid is at or above atmospheric pressure. The invention provides an improved method of carrying out the process of filling of tanks with liquids such as ammonia, chlorine, propane, liquefied petroleum gas or any other liquid with high vapor pressure at the temperature of operation. The main advantage provided by the apparatus and method of the present invention is that an improved means is included for automatically stopping the filling process at the correct point, so as to avoid a possibly hazardous overfilled condition. One of the methods currently in use requires a mechanical valve which senses liquid level in the tank and is supposed to close so as to stop flow to the tank when the liquid has reached the maximum allowable level.Type: GrantFiled: March 11, 1996Date of Patent: August 12, 1997Inventor: Edward J. Farkas
