Abstract:

A cross sealer for a bag making machine includes a frame with an upper seal bar unit and a lower seal bar unit in aligned opposed relation. One is movable seal bar unit which includes a rigid support beam of a lightweight construction and a light weight seal bar connected to the beam by a plurality of adjustable stud units for adjusting the position of the seal bar. A rotating shaft spans the cross sealer and is connected by a plurality of eccentric linkages to the beam between side plates of the frame. The linkages support the beam and seal bar and transfers the sealing force onto the beam and bar for moving the bar into sealing engagement across the width of the web. The opposed seal bar unit is similarly constructed with a beam and a seal bar with the units interconnected by adjustable stud connectors. The second seal bar unit is mounted as a substantially stationary unit and includes a plurality of substantially fixed connectors supporting of the fixed beam along a plurality of locations to form a relatively rigid beam support. Alternate fixed beam supports include air cylinders to provide a cushion support for the seal unit.

Abstract:

A slush hydrogen production device ( ) utilizes a hydrogen slushifier magnetic refrigerator ( ) having a wheel ( ) of material exhibiting the magnetocaloric effect. The wheel is rotated through a magnetic field of varying intensity around the circumference of a wheel housing ( ) created by the windings of superconductive magnets ( ). The material of the wheel ( ) follows a magnetic Carnot cycle as the wheel rotates ( ) through regions of low temperature heat transfer and high temperature heat transfer. Liquid hydrogen is supplied to the regions of low and high temperature heat transfer through inlet pipes ( and ). Gaseous hydrogen is produced in the high temperature heat transfer region and vented away by an outlet pipe ( ). Solid hydrogen is produced in the low temperature heat transfer region by direct solidification upon the magnetic wheel ( ); and is removed by scrapers ( ) and deposited in a compartment ( ) where it mixes with liquid hydrogen to form slush hydrogen. A second magnetic refrigerator ( ) may be used to keep its magnets and the magnets of the hydrogen slushifier magnetic refrigerator ( ) at a temperature region suitable to maintain superconductivity.

Abstract:

A flat plastic bag is formed from a side gusseted tubular web. The bag is formed with an open end and a opposite spaced end seal. Hinge crease patterns are formed in each of the gusseted portions at the bottom end of the bag. The pattern includes a two ridge upper leg and a three ridge bottom leg which are formed by a cold sealing process. A bag making machine includes a web supply which is passed through a web feed supply section to form the gusseted web. The gusseted web is sent through a forming section. The segment is first formed with the patterns of two bags in immediately adjacent relationship and located to the opposite sides of a common line defining the end of the adjacent bags. The web is formed into two bag segments with the creases located at each of the segment ends. The web is passed through a unit creating the seal and simultaneously severing the upstream segment.

Abstract:

The rotary dipole active magnetic regenerative refrigerator (10) of the present invention comprises a stationary first regenerative magnetic bed (12) positioned within a stationary first inner dipole magnet (14), a stationary second regenerative magnetic material bed (16) positioned within a stationary second inner dipole magnet (18), an outer dipole magnet (20) that rotates on a longitudinal axis and encloses the inner dipole magnets (14, 18), a cold heat exchanger (22), hot heat exchangers (24, 26), a fluid displacer (28), and connective plumbing through which a heat transfer fluid is conveyed. The first and second regenerative magnetic beds (12, 16) are magnetized and demagnetized as the vector sums of the magnetic fields of the inner dipoles magnets (14, 18) and the outer dipole magnet (20) are added together upon rotation of the outer dipole magnet (20), such magnetization and demagnetization causing a correlative increase and decrease in the temperature of the magnetic material beds (12, 16) by the magnetocaloric effect. Upon magnetization of any particular magnetic material bed (12 or 16), fluid flow is forced therethrough in the connective plumbing by the fluid displacer (28) in the direction from the cold heat exchanger (22) to one of the hot heat exchangers (24,26). Upon demagnetization of any particular magnetic material bed (12 or 16), fluid flow is reversed by the fluid displacer (28) and is forced in the direction from one of the hot heat exchangers (24, 26) to the cold heat exchanger (22).

Abstract:

A magnetic refrigeration apparatus (10) is modular in design, so that housing modules (14) are alternately stacked with superconducting magnet pairs (24). Each module (14) has a wheel (16) that is rotated through the module (14), the wheel (16) having cutout regions (18) into which elements (20) of magnetic material are inserted. Each cutout region has two elements (20) separated by a wave spring, the wave spring biasing the elements (20) against the housing module (14) so that the elements (14) are in slidable contact with the module (14) upon rotation. In operation, the wheel (16) carries the elements (20) cyclically between high and low magnetic field zones. In low field regions the elements (20) are cooled by the magnetocaloric effect and heat exchangers absorb heat from either a stagnant subcooled superfluid helium bath or a forced-flow subcooled superfluid helium stream. In high field regions the elements (20) are heated by the magnetocaloric effect and a force-flow stream of liquid helium passes through the high temperature heat exchangers absorbing heat from the magnetic refrigeration apparatus (10).
