Abstract: Method and apparatus for detecting bulged and sunken sidewalls and incorrect widths on paneled containers.Containers to be inspected are moved along a conveyor. Two groups of three LVDT's (generally opposite from one another) are utilized to measure the distance between each of three points on the container sidewall and a reference line. The measurements are fed to a circuit which determines the deviation of one of the three points from a line passing through the remaining two points. The amount of deviation is utilized to determine whether or not the sidewall is bulged or sunken. Measurements from each pair of opposing LVDT's are fed to a circuit which determines the width of the container at three different heights. The width values are compared to predetermined limits in order to determine if the container width is acceptable.The timing of measurements is controlled by the use of photocell sensors, which detect the passage of a container past particular reference points.

Abstract: A fluid collection apparatus is disclosed which is useful in separating blood serum or plasma from blood cellular and particulate matter. The apparatus comprises an elongated hollow body closeable at both ends with a self sealing septum near one end. The septum includes a central cavity extending axially from one end of the septum and terminates in a web portion. The septal web portion is pierced by a composite piston member which includes a passageway equipped with a filter. Fluid, therefore, flows through the filter, the piercing means and into the hollow body. A flange on the composite piston extends laterally of the hollow body and sealingly engages the inner wall of a tube filled with a sample of mixed materials.Upon withdrawal of the apparatus, the composite piston remains sealed in the sample containing tube. The web portion of the hollow body reseals on withdrawal of the piercing means to prevent leakage.

Abstract: This invention provides an apparatus for mounting, driving and steering the wheels of a high mobility wheeled vehicle, such as those used over roadless terrain in tree harvesting operations. Each vehicle wheel is mounted on a rotatable hub which is in turn journaled on the end of a wheel drive housing. The housing is medially pivoted to the wheel suspension structure of the vehicle for steering movements and has a driving motor mounted on the inner end of the housing and connected to the wheel hub through an appropriate gearing system. The pivotal mounting of the drive housing is preferably located at the end of a walking beam arm which is disposed at a substantial horizontal angle with respect to the longitudinal axis of the vehicle to provide clearance for steering movements of the vehicle wheel. The steering motion is imparted to the drive housing by an actuator which is connected between the inner end of the drive housing and the inner end of the walking beam arm.

Abstract: The present invention relates to an apparatus for forming and applying a plastic sleeve to a rigid base article, such as a glass bottle. A blank of plastic is wrapped and seamed around the fingers of a stripper sleeve enclosing a mandrel. The stripper sleeve holding the plastic sleeve is extended along its longitudinal axis telescopically over a preheated bottle positioned above and longitudinally aligned with the mandrel and the stripper sleeve. Clamping means, such as a plurality of vacuum fingers, extend downwardly and hold the plastic sleeve in position while the stripper sleeve with its fingers is retracted to its original position. The heat of the bottle causes the plastic sleeve to shrink slightly such that it is held in position relative to the bottle when the clamping means is removed. The bottle and plastic sleeve are then subjected to a thermoconstrictive operation.

Abstract: Apparatus and method for measuring the volume and shape of a falling gob of glass. Two cameras are used to make section by section measurements of the horizontal extent of the moving gob. Timing of the measurements is controlled so as to cause measurements to be made at equal increments of the motion of the gob. The measurements are made 90.degree. apart with respect to the gob and are utilized to determine the volume of each section of the gob. The volumes of the individual sections of the gob are then summed to determine the total volume of the gob. An image of the gob is generated on a television screen to aid in the determination of the shape of the gob.

Abstract: This invention relates to the art of coating glassware while the ware is moving through an annealing lehr which is provided with a cooling section near the exit end of the lehr. The cooling section is of the continuous recirculation type providing an arrangement for generally cooling the ware to a relatively even temperature even though the ware is moving through the lehr in multiple rows and columns. The ware is moved through the lehr on a lehr belt which is formed as a webbed belt and constitutes a foraminous conveyor. A lubricious material in the form of a vapor or mist of an organic, non-metallic coating material selected from the group consisting of polyolefins, fatty acids and their derivatives is injected into the recirculating cooling air in the cooling section of the lehr to thereby form a durable lubricious coating on the exterior surfaces of the glass article. The articles, at the time they are passed through the cooling section, will be at a temperature between 200.degree. F. and 400.degree. F.
