Abstract: A slitting and scoring machine includes an upper tooling roller and a lower tooling roller that cooperate to define a tooling nip. Each tooling roller includes an alternating series of coaxially arranged annular knives, annular dies, and annular mandrels. A web of insulation is drawn through the tooling nip to simultaneously (i) cut the web into strips, (ii) score the strips in a manner that promotes the forming of the strips, and (iii) partially form the strips into modified U-shapes. Each strip includes a longitudinally extending middle segment and a pair of longitudinally extending side segments that extend away from the middle segment in a divergent manner to define a longitudinally extending channel. Longitudinally extending grooves are formed by the scoring at the junctures of the middle segment and the side segments. The scoring / grooves promote the divergent shape of the strip. In an end profile view of the strip, the middle segment and each of the side segments are generally straight, and an obtuse angle is defined between each side segment and the middle segment. Each strip is formed into a roll, so that a first length of the strip and a second length of the strip each extend around a common point. At least a portion of the second length is disposed within the channel of the first length.

Abstract: An advantageous scheduling template slot ordering for use in establishing a scheduling order of events such as transmitting communication signals in a communication network is determined by assigning at least two initial slot positions to a particular signal class and then determining a regularity measurebased on a lower bound for the regularity measure of such assignments and the remaining unassigned slot positions. This lower bound for the regularity measure of the unassigned slots is advantageously based on a hypothetical assignment of fractions of the slot positions to different signal classes instead of limiting the assignment of a slot to a single signal class. This fractional slotassignment produces a regularity measure that is better than or equal to a corresponding regularity measure based on assigning a whole slot to a particularsignal class. The lower bound of the regularity measure is then compared with a threshold regularity measure, such as from a known reference scheduling template. If the threshold regularity measure is lower than the determined lower bound, then it is known that the reference template would provide a more desirable regularity of events than any template having the assigned slot positions to that particular signal class. As a consequence, other slot assignments can be compared to the reference template to rapidly identify scheduling templates with enhanced regularity characteristics.

Title: Vertically adjustable wheel assembly
Inventor: MANDEL SHELDON W
IPC: B60B33/06
Filed: 1998-05-22
Granted: 2004-11-23
Abstract: A vertically adjustable wheel assembly for movably supporting an appliance cabinet or the like upon a supporting surface includes a housing, a supporting bracket, a wheel unit, an adjusting rod, an adjusting screw and various elongated mounting members. The wheel unit is defined by a pair of spaced rollers that are interconnected by a reduced diametric portion. The wheel unit is rotatably attached to the support bracket by an axle member, while the adjusting rod is also mounted for rotary movement by the support bracket.      The support bracket is pivotally mounted to the housing, with both the wheel unit and the adjusting rod being permitted to rotate relative thereto. The adjusting screw extends through a frontal portion of the housing and it is threadably connected to the adjusting rod such that rotation of the screw causes pivoting of the support bracket relative to the housing and movement of the wheel assembly between fully extended and fully retracted positions. With the rollers of the wheel unit being laterally spaced, the adjusting screw is permitted to extend between the rollers when the adjustable wheel assembly assumes the retracted position. The arrangement represents an extremely compact vertically adjustable wheel assembly that can be advantageously preassembled and attached to a refrigerator cabinet or the like as a unit.

Abstract: L'invention concerne un instrument pour mesurer une douleur ou la sensation de nausée chez un patient. L'instrument de mesure induit une douleur dans une partie arbitraire du corps du patient, en appliquant un courant électrique. L'instrument de mesure permet d'augmenter le courant appliqué à cette partie du corps jusqu'à ce que la douleur induite soit ressentie par le patient comme étant égale à la douleur/nausée existante. Le courant est appliqué depuis une source de courant placée dans l'appareil de mesure, par l'intermédiaire de fils métalliques (H. I) et d'électrodes (C, D), lesquelles sont appliquées sur la partie du corps où l'on veut induire une douleur. Quand la douleur induite est ressentie comme égale à la douleur/sensation de nausée du patient, les électrodes sont détachées du corps et la valeur de la douleur est enregistrée et affichée sur un écran (F).

Abstract: The present invention relates to a method of and an apparatus for purifying the exhaust gas of an internal combustion engine. The invention is comprised of an NOx purifying catalyst arranged in an exhaust gas passage, The NOx purifying catalyst is made of a composite material containing at least one kind of element selected from alkaline metals and alkaline earth metals, at least one kind of element selected from rare earth metals, at least one kind of element selected from platinoid metals, and titanium (Ti). The NOx purifying catalyst adsorbs NOx in the exhaust gas onto the surface when the exhaust gas is lean, and reduces the adsorbed NOx to N2 when the exhaust gas is stoichiometric or rich. The exhaust gas is purified by adsorbing NOx in the exhaust gas in the NOx purifying catalyst when the internal combustion engine is being operated under a lean condition, and by setting, after the adsorption, the exhaust gas to a stoichiometric state or a rich state for 0.5 second to 4.5 seconds to reduce the NOx adsorbed in the NOx purifying catalyst to N2 through catalytic reaction with the reducing agent.
