The drive device and the motor housing move with the drive spindle as co-vibrating units during an operation of the separator. The drive device is connected to the machine frame below the bearing at a lower axial end of the bearing via one or more joint elements.

A unitary elastic mold and cutter combination configured to mold and cut moldable material is disclosed herein. The mold and cutter combination comprises an elastic mold cavity having an elastic bottom wall with an embossed inner surface and an elastic sidewall extending from and unitary with a perimeter of the bottom wall. An elastic cutting blade extends from and is unitary with the sidewall of the mold cavity and is configured to cut moldable material and maintain a substantially consistent perimeter upon cutting. The cutting blade comprises a cutting edge disposed between an inner cutting blade surface and an outer cutting blade surface. The mold and cutter combination may have an elasticity sufficient to release molded material therefrom by hand stretching, wherein the cutting edge, inner cutting blade surface, and the inner surface of the sidewall of the mold cavity are stretched by an amount sufficient to release the molded material.

An improved liner having an elastic securing mechanism that may be placed in a vessel to form and maintain a barrier between the vessel and objects contained therein. The liner includes an elastic securing band secured around the perimeter of the open top end of the liner using a plurality of spaced-apart tack welds or rivets. In one embodiment, the liner material is folded over the elastic and ultrasonic sealing is used to burn through the elastic and seal the folded liner material to itself thereby securing the elastic to the liner. In use, the liner is placed within a receptacle of the vessel and the open top end is folded outward and downward over a rim of the vessel such that the elastic engages an outside of the vessel to form a secure and snug fit of the liner to the vessel. Advantageously, a failure to a portion of the elastic is limited to that portion of the elastic only and propagation of the failure is limited by the rivets.

A yarn supply apparatus for elastic yarns in knitting machines having abruptly fluctuating yarn consumption. A yarn wheel, around which the yarn to be supplied is wrapped, furnishes the yarn to a yarn store located between a knitting station and the yarn wheel. A closed-loop controller responsive to yarn tension operates the yarn wheel via a low-inertia drive motor. The yarn store is embodied as an essentially straight segment of yarn in the yarn path in which yarn is guided so it can expand freely. The combination of a low-inertia drive motor, a yarn store that utilizes the intrinsic elasticity of the yarn, and a closed-loop controller that monitors the yarn tension by means of a sensor device makes it possible to use the yarn supply apparatus for supplying elastic yarns and to keep the yarn tension essentially constant even when the demand for yarn fluctuates abruptly.

The two contact wires (1, 2) of the elastic contact line system are located along the cantilever parallel to the first contact wire (4), which is, in turn, clamped over the entire length of the cantilever. All three contact wires (1, 2, 4) are affixed on several multiple clamps (9) in the area of the cantilever (5), which clamps are located in a distributed manner along the cantilever. The multiple clamps (9) are located in recesses (12) of the cantilever.

The invention involves foaming soaking compositions that have some or part of the anionic surfactant present in the same replaced with an extended chain anionic surfactant.

A method of dispensing adhesive onto a stretched elastic strand includes applying a first volume of adhesive onto a first portion of the elastic strand, applying a second volume of adhesive onto a second portion of the elastic strand, and applying a third volume of adhesive onto a third portion of the elastic strand. The second volume is less than the first and third volumes. When the elastic strand is adhered to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive to resist creep at the opposing ends. The reduction of adhesive in the second or central portion between the opposing ends significantly reduces the adhesive add on in the personal disposable hygiene product.

Abstract:
In large-scale quantitative proteomic studies, scientists measure the abundance of thousands of proteins from the human proteome in search of novel biomarkers for a given disease. Penalized regression estimators can be used to identify potential biomarkers among a large set of molecular features measured. Yet, the performance and statistical properties of these estimators depend on the loss and penalty functions used to define them. Motivated by a real plasma proteomic biomarkers study, we propose a new class of penalized robust estimators based on the elastic net penalty, which can be tuned to keep groups of correlated variables together in the selected model and maintain robustness against possible outliers. We also propose an efficient algorithm to compute our robust penalized estimators and derive a data-driven method to select the penalty term. Our robust penalized estimators have very good robustness properties and are also consistent under certain regularity conditions. Numerical results show that our robust estimators compare favorably to other robust penalized estimators. Using our proposed methodology for the analysis of the proteomics data, we identify new potentially relevant biomarkers of cardiac allograft vasculopathy that are not found with nonrobust alternatives. The selected model is validated in a new set of 52 test samples and achieves an area under the receiver operating characteristic (AUC) of 0.85.

Atherosclerotic cardiovascular diseases are rooted in childhood. Vascular intima-media thickness (IMT) and elasticity are early surrogate markers of atherosclerosis. In adults, cardiorespiratory fitness is associated with enhanced arterial elasticity and decreased IMT.

Fitness was favorably associated with aortic IMT and elasticity in adolescents. The association was independent of several cardiometabolic risk factors. In fit adolescents, the increase in IMT during the preceding 6 years was smaller compared with low-fit peers. (Read the full article)

This paper estimates the elasticities of government revenue and expenditure items with respect to the output gap for European Union (EU) countries. These elasticities are used by the European Commission, as part of the EU fiscal surveillance process, to calculate the semi-elasticity of the budget balance as a percentage of GDP with respect to the output gap.

This paper re-estimates the elasticities of government revenue and expenditure items with respect to the output gap for OECD countries. These elasticities are used by the OECD to calculate cyclically adjusted fiscal balances. The study updates the earlier 2005 study using the most recent datasets and tax codes, the coverage being confined in this paper to 35 countries, the 34 OECD member states and Latvia.
