Patent number: 5755074Abstract: A down-article indicator which automatically adjusts for the height difference of articles, such as bottles, when article size is changed for a new run on a machine conveying articles. A pivotably mounted height sensing arm, located on one lane of the machine, down stream from an array of freely pivoting detecting arms, is connected by an adjustable mechanical linkage to a pivoting bracket holding a retro-reflective photo eye in proper location with respect to the detecting arms so that the detecting arms do not break a light beam from the photo eye during normal operation. A non-upright article will cause a detecting arm to pivot and break the light beam to stop the machine. As a new group of articles having a different height moves into the down-article indicating station, the height sensing arm automatically moves the photo eye to its proper location for the new height articles.Type: GrantFiled: March 21, 1997Date of Patent: May 26, 1998Assignee: Riverwood International CorporationInventor: Shawn M. Fetters

Patent number: 4803744Abstract: This invention is concerned with an improved air bed system. In this invention, the bed occupant can control the firmness of the bed. Two inflatable bladders are used with a pre-set pressure differential between them. The pressure in the lower bladder is always kept high enough to prevent bottoming of a bed occupant. The pressure in the upper bladder can be adjusted by the occupant to his or her own personal comfort level. The invention may also include various medical devices which are fluid powered, thus taking advantage of the presence of the pressurized working fluid. The invention may further include a warning circuit which senses the departure of an occupant from the bed and generates a warning signal in response thereto.Type: GrantFiled: May 19, 1987Date of Patent: February 14, 1989Assignee: Hill-Rom Company, Inc.Inventors: William H. Peck, Michael E. Poehner

Patent number: 4751754Abstract: A hydraulically operated hospital bed with dual hydraulic power systems for operation with or without electrical service. The bed has its head and thigh/leg elevation functions performed by hydraulic cylinders. A control circuit meters the introduction and removal of hydraulic fluid from these cylinders so an occupant of the bed is not subjected to any sudden movement. In case of an emergency requiring the bed occupant to be in a supine position (the need to perform CPR), the normal control circuit is bypassed by an emergency circuit that allows much faster than normal lowering of the head and thigh/leg portions of the bed.Type: GrantFiled: April 2, 1987Date of Patent: June 21, 1988Assignee: Hill-Rom Company, Inc.Inventors: David W. Bailey, Michael J. Duwell, William H. Peck

Patent number: 4724555Abstract: A hospital bed footboard is provided which can be moved from the normal, vertical position of a bed footboard to a horizontal position overlying the bed. The support for the footboard in the overbed position is of a fully cantilevered nature so no impediment is placed to approaching the patient from the sides of the bed, nor is the overall width of the bed increased. The footboard when positioned over the bed can serve as a shelf for holding monitoring and life support devices during patient transport.Type: GrantFiled: March 20, 1987Date of Patent: February 16, 1988Assignee: Hill-Rom Company, Inc.Inventors: Michael E. Poehner, Jeffrey R. Welling

Patent number: 4523904Abstract: In a blow molding apparatus where a plurality of sets of molds are mounted on a wheel rotatable about an axis and the molds are moved toward and away from one another to enclose a parison and the parison is blown to the confines of the cavity between the mold sections as the wheel rotates by the application of air, an apparatus for controlling the application of the air comprising a valve assembly associated with each set of molds on the wheel and comprising a valve which is opened and closed to control the flow of air to the mold. The valve assembly includes a rotatable cam for moving the valve to open and closed positions, a starwheel associated with the cam, and a first actuator mounted at a first position along the path of the wheel for engagement with the starwheel to rotate the cam and open the valve and a second actuator mounted at a second position along the path of the wheel for engagement with the starwheel to rotate the cam and close the valve.Type: GrantFiled: March 28, 1984Date of Patent: June 18, 1985Assignee: Owens-Illinois, Inc.Inventor: Merritt W. Martin

Patent number: 4514209Abstract: The feeder tube in a molten glass gob feeder is mounted in a holder which is supported in the feeder structure by a pair of opposed hollow shafts. The shafts are vertically adjustable by the fact that they have their lower ends threaded onto vertical screws. The vertical screws are mounted for rotation about their vertical axes, in unison, to effectively raise or lower the shafts as desired. A scale and pointer arrangement indicates the tube height relative to the feeder bottom. The feeder tube is mounted in the holder such that reciprocation of a plunger in the tube will not raise the tube relative to the feeder.Type: GrantFiled: December 1, 1983Date of Patent: April 30, 1985Assignee: Owens-Illinois, Inc.Inventor: Eustace H. Mumford

Patent number: 4513860Abstract: A bottle carrier for carrying a plurality of bottles having a body portion and a neck portion and a closure which is attached to the neck of the bottle which comprises a generally flat blank formed of a material that is flexible and elastic. The blank comprises a first part defining a central portion and a second part defining a band which is severable from the first part and is adapted to be stretched about a group of bottles. The first part comprises a plurality of openings in spaced rows for receiving the necks of the containers and engaging the necks below the closures. In order to meet the requirements of adequately securing the bottles in the carrier and at the same time, being able to apply the carrier to the bottles rapidly by automatic machines, the carrier includes the following relationships: (1) minimum widths of the webs between the openings for receiving the necks of the bottles and the periphery of the carrier, (2) the stress on the webs must be less than 550 p.s.i.Type: GrantFiled: September 9, 1983Date of Patent: April 30, 1985Assignee: Owens-Illinois, Inc.Inventor: Roger R. Rhoads

Patent number: 4512792Abstract: The cooling wind for the molds on a glass bottle forming machine is controlled by a damper which is set by hand and positioned in the air passages from the section box or base of a glass forming machine and a nozzle base bolted to the top of the section box. As a further control for the air a piston operated vane positioned such that it will shut off the air to the air passages upon receipt of an air signal from the timing system of the machine is provided and is to be operated each cycle of the machine to prevent cooling air from impinging on bare glass.Type: GrantFiled: July 11, 1983Date of Patent: April 23, 1985Assignee: Owens-Illinois, Inc.Inventors: George W. Irwin, Eustace H. Mumford

Patent number: 4511385Abstract: A centerline cooled forehearth for conditioning molten glass, wherein the sides of the flow channel of the forehearth are provided with external sheets of insulation. The channel is covered by a roof having vertical vents therethrough along the centerline with the usual burner blocks and burners spaced along the sides of the upper edge of the channel. Flue blocks are positioned immediately above the burner blocks, and their lower surfaces extend toward the centerline of the channel a greater extent than the burners, thereby serving as reflectors for the heat from the burners along the side walls of the channel.Type: GrantFiled: October 17, 1983Date of Patent: April 16, 1985Assignee: Owens-Illinois, Inc.Inventors: Marvin L. Barkhau, Joseph J. Kujawa

Patent number: 4268975Abstract: This invention relates to an apparatus for effecting the uniform pre-heating of thermoplastic parisons of the type that are introduced into a blow molding machine for fabrication into a blow molded article. The invention provides a hopper which is intermittently supplied with batches of parisons and through which the parisons move by gravity. A convection heating zone is provided in the hopper to uniformly heat each parison passing therethrough, and a temperature equalization zone is provided adjacent to the heating zone. The parisons are removed from the temperature equalization zone by a continuously moving parison conveyor which forms part of the temperature equalization zone.Type: GrantFiled: January 28, 1980Date of Patent: May 26, 1981Assignee: Owens-Illinois, Inc.Inventors: Wayne E.
