摘要： The present invention comprises a rotary carrier which carries a plurality of semi-spherical gripping heads having concave gripping surfaces. The gripping heads are positioned such that the gripping surfaces become flush with the forwardmost plate in a vertically arrayed stack of plates as the carrier rotates. Each gripping head is mounted to the carrier through a hollow bellows and vacuum air drawn into a hole in the gripping face passes through the bellows. When the vacuum increases, due to the forwardmost plate in the stack being pulled up against the gripping head, the bellows collapses and pulls the forwardmost plate away from the stack. Rollers, which extend beyond the periphery of the carrier, urge the stack away from the gripping head immediately before they become aligned. The vacuum then pulls the forwardmost plate away from the stack and into contact with the gripping head before the bellows collapses thereby increasing the gap between them. Vacuum is provided to the gripping head through a passageway which opens out of an opening in the carrier. A first sector plate, which is journaled on the carrier axle but does not rotate with the carrier, has a slot passing through it which overlies the opening in the carrier when they are aligned. A second sector plate, which overlies and is attached to the first sector plate, has a hole in it which opens into the slot in the first sector plate. A vacuum tube extends between this opening and a vacuum source.

摘要： Method and apparatus for removing processing oil from thin sheets of microporous plastic material is comprised of a tank having a liquid zone in its bottom portion which is divided into three sub-tanks having decreasing depths extending across the tank. Heating coils in each sub-tank vaporize the solvent to form a cleaning zone, containing vaporized solvent, above the liquid portion, and condensing coils located at the top of the tank condense the vaporized solvent and deposit it into the deepest sub-tank which also is supplied freash make up solvent when required. A series of rollers feeds the material through the tank, from the side having the shallowest sub-tank toward the side having the deepest sub-tank, while repeatedly passing it between the cleaning zone where solvent is condensed on it to clean it, and the condensing zone where it is cooled to a temperature below the temperature of the vaporous solvent. Precondensing coils located medially in the tank between each pass of the material as it extends between the condensing zone and the cleaning zone and vice versa, define the extent of the cleaning zone and direct condensed solvent onto the material to wash it. Soiled solvent is removed from the shallowest sub-tank and evaporatively separated from the oil carried in it and reintroduced into the tank as vapor. After the oil has been removed from the material the solvent is displaced by pressurized steam which is directed onto the material and the steam then is removed from the material by passing it through a heater.

摘要： The calender rolls of the present invention are comprised of relatively thin-walled hollow shells which are supported at each end by shafts having bores which extend into the cavities formed in the rolls. Fittings located at the ends of the shafts are rotatable relative to them so that by tying the fittings together they do not rotate along with the rolls. The fittings at one of the ends of the rolls are connected to a source of wet steam through a pressure regulator and the fittings at the other ends carry probes which extend through the shafts and curve downwardly towards the bottoms of the rolls. A valve regulates the amount of material which flows out of the cavities through the probes. The method by which the rolls are used comprises introducing wet steam into the cavities, maintaining its pressure at a constant level. Since the temperature of wet steam depends upon its pressure, by controlling the pressure of the steam in the cavities and maintaining it at a constant pressure the outer surfaces of the rolls can be maintained at a constant desired temperature, irrespective of the effect of the temperature of the material being calendered or of ambient temperature.

摘要： A leak detector comprises a detector head which is to be scanned across a surface to detect a signal gas eminating from the surface. The opposite side of the surface from the head is supplied with a signal gas under pressure so that signal gas passes through leaks in the surface. Detection of signal gas by the head should then constitute detection of a leak. A curtain 1 of barrier gas is provided around a sample inlet 2 to protect the inlet from spurious signal gas. Orifices 36 provide narrow high velocity jets 38 which impinge on the surface S within curtain 1 and break up jets such as 34 of signal gas which escape under the curtain 1 without allowing the signal gas to reach the sample inlet.
