A method and mechanism for continuous wrapping of objects in a product package having a reclosable zipper thereon, providing a continuous sheet of thermoplastic film with a reclosable rib and groove fastener profile extending therealong parallel to the formation axis of the film with the profiles interlocked to form a flattened closure, guidingly wrapping the sheet around the object, simultaneously guiding the interlocked fastener to an upright position relative to the object, and flattening the...

A method and apparatus for mounting a panel on a rail member having first and second resilient legs separated by a channel. A groove disposed along a first side of the panel receives a portion of one of the resilient legs of the rail member. The groove extends from a lower surface of the panel toward an upper surface of the panel so that the upper surface extends over the resilient leg received in the groove. The groove includes a first side surface with a first inclined portion and a second sid...

A high resolution continuous tone medical image printer is capable of printing a high resolution image on a plurality of different sized media. In a normal resolution mode, a medical image of m.times.n pixels is printed on a first sized media with a variable pixel clock operating at a first pixel clock rate, and in a second resolution mode where the medical image of m.times.n pixels is printed on a second sized media larger than the first sized media in either or both the line scan direction and...

A wrapping machine and a method for wrapping a plastic foil web (F) around an object. A gripping and cutting device (11) is connected to a lifting frame (3) supporting a circular guide track of a foil dispenser (6) so as to be vertically movable with the lifting frame. In the method, the wrapping action is started from a freely chosen point relative to the vertical direction of the object and ended correspondingly at a freely chosen point relative to the vertical direction of the object.

In a wrapping machine for wrapping a plastic foil web (F) around an object, a gripping and cutting device (11) is connected to a lifting frame (3) supporting a circular guide track of a foil dispenser (6) so as to be vertically movable with the lifting frame.

An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greate...

A liquid light guide system for ultraviolet light is disclosed that has a light shaping arrangement for the emitted light, a stable liquid core and sheath and reliable and effective end closures. The end closures include a metal crimping arrangement that utilizes two layers of deformable materials to prevent cracking of endplugs.

A termination for a light guide having optical cladding tubing and a liquid core includes a volumetric change device configured to allow fluid flow out of the tubing whenever the liquid core expands and to allow fluid flow into the tubing whenever the liquid core contracts, an end plug fixed to the tubing to retain the liquid in the liquid core within the tubing and the end piece and a crimping piece for holding the end plug in place.

A circuit for generating a clock or sampling signal, the circuit including: a semiconductor quantum dot laser element including a region of quantum dots, wherein the region of quantum dots is characterized by an emission distribution having a half-width of at least about 10 meV; and drive circuitry connected to the quantum dot laser element for operating the quantum dot laser element as a mode-locked laser that outputs a periodic, uniformly spaced sequence of pulses, wherein the clock or samplin...

An electronic device package is made by first making in a stencil member (11) an opening (12) in the shape of a closed loop that surrounds an inner portion (13) of the stencil member. The closed loop is a continuous opening except for a plurality of web members (15), each of which extends across the opening to secure the inner stencil portion to the remainder of the stencil member. A glass slurry (7) is forced through the opening of the stencil member onto a first substrate (18) so as to form on...
