Title: High speed interfolder
Inventor: KAUPPILA GREG
IPC: B31B1/14
Filed: 2006-10-10
Abstract: An interfolding apparatus including a knife roll rotatable about an axis and operable to cut successive sheets from a stream of web material issuing from a source in a downstream direction. A folding roll is positioned downstream of the knife roll and is rotatable in a first direction at a first roll speed. An additional roll is disposed adjacent to the folding roll and is rotatable about an axis in a second direction at a second roll speed. The additional roll is operable to receive the successive sheets and release the successive sheets in the downstream direction toward the folding roll. The folding roll and the additional roll define a nip therebetween, the successive sheets passing through the nip. The first roll speed of the folding roll is different from the second roll speed of the additional roll, the difference in speed between the folding roll and the additional roll operable to overlap adjacent portions of the successive sheets onto the folding roll.

Title: Methods and systems for designing primers and probes
Inventor: KEDEM GILEAD
IPC: G16B30/10
Filed: 2006-11-29
Abstract: The invention provides methods for designing polynucleotide primers and probes that are optimized for hybridizing to a plurality of target nucleic acid variants by employing scoring and/or ranking steps that provide a positive or negative preference or "weight" to certain nucleotides in a candidate nucleic acid sequence. The particular scoring or ranking steps performed depend upon the intended use for the primer and/or probe, the particular target sequence, and the number of variants of that target sequence. The methods of the invention provide optimal primer and probe sequences because they hybridize to more target nucleic acid variants than primers and probes in the prior art.

Abstract: The present invention provides a separator for use in a roller element bearing assembly including two identical separator rings, each having a plurality of cooperating cut-out portions formed at predetermined intervals and circumferentially about an outer planar surface. A decrease in the thickness of the two separator rings is realized at the cut-out portions. A plurality of rivets are positioned within the plurality of cooperating cut-out portions to clamp the two separator rings together.  The decrease in the thickness of the separator rings where the rivets are positioned enables shorter rivets to be used, thus minimizing buckling of the rivets and fracture of the rings, as well as a continuous un-interrupted piloting surface.

Abstract: A method for assembling a ball and socket assembly (10) includes loading a housing (14) with a resilient preload washer (28), an inner bearing (30), a ball stud (12) and an outer bearing (36). A loading tool (50) forcefully compresses the assembled components, as a unit, to an overload compression condition (54), and then reduces the compression until an ideal compression condition (56) is achieved. The outer bearing (36) is staked in position while the loading tool (50) holds the assembled components in the ideal compression condition (56). Following the staking operation, the loading tool (50) can be removed, and a final crimping operation permanently sets the outer bearing (36) in position and holds the articulating components in the ideal, pre-load clearance established. The subject method is particularly well-suited for high production set-ups in which precise pre-load clearances must be achieved at high through put rates.

Abstract: Facilitation of web page rendering using dynamic rendering controls. A server identifies a representation of a page to be downloaded to a client. The representation includes a dynamic rendering control that may be used to render a portion of the page. Rather than leaving it to the client to gain access to the initial set of data that is to be used by the dynamic rendering control to properly render, the server estimates the initial set of data that is to be used, and transmits a network response that includes the estimated initial set of data. When executing the rendering component, the client may simply use the data provided in the network response to render the portion of the page, rather than having to gain access to the data from a network source.

Abstract: A phasor representation of an electrical entity at a geographical location in a multiple phase AC electric power system is produced by receiving a synchronization signal from a remote source, producing a sampling time signal in response to the synchronization signal and a local reference time signal, and producing samples representing an amount of the entity in respective ones of the phases in the AC power system in response to the sampling time signal and the electrical entity in respective ones of the phases in the AC power system. A transformation is performed on the samples to produce a two-axis rotating reference frame representation of the electrical entity in a two-axis rotating reference frame. For each sample, a representation of a sampling time associated with the sample is produced. The two-axis rotating reference frame representation and the representation of the sampling time comprise the phasor representation.

Abstract: This invention relates to methods of shaping the anterior surface of the eye for controlling the progression of refractive error of the eye, in particular, myopia. The method employs the fitting of orthokeratology lenses having a precisely shaped posterior surface adapted to accurately shape the peripheral region of the eye. The method includes the steps of assessing central and peripheral refractive error parameters for the eye, determining the optimal anterior surface profile for the eye, including at both the optical centre of the cornea and at a selected optical periphery of the cornea, which would result in a desired refractive correction to achieve good vision for the eye and the desired peripheral refraction (curvature of field) for the eye for controlling progression of myopia. Accurate measurement of the shape of the pre-treated eye is important, thereby enabling a corresponding lens profile to be designed or selected so that the treatment process achieves a post-treatment peripheral profile which optimally focuses peripheral rays anteriorly of the retina, thereby controlling the progression of myopia. The invention extends to a lens manufactured so as to optimally treat the peripheral region of the eye.
