Abstract: The efficiency of heat transfer to a furnace tube or coil in a furnace for cracking ethane, propane or naphtha feedstocks, or a mixture thereof may be improved by providing protuberances on the surface of the tube or coil having i) a maximum height from 3 to 15% of the coil outer diameter, ii) a contact surface with a coil, or a base, which area is 0.1%-10% of the coil external cross section area, and iii) a geometrical shape which has a relatively large external surface containing a relatively small volume.

Abstract: Single site reactor/catalyst continuity in a dispersed phase reaction in terms of initial activation and subsequent deactivation may be improved by treating the support with a metal salt. The activator and catalyst are then deposited on the treated support. The resulting catalyst has a lower consumption of ethylene during initiation and a lower rate of deactivation. Preferably the catalyst is used with an antistatic agent.

Abstract: The oligomerization of ethylene using a chromium catalyst and an aluminoxane activator is well known. The undesired formation of polyethylene as a by-product is also known to occur during prior oligomerization processes. We have discovered that the use of an aluminoxane that is prepared by non-hydrolytic means provides a highly productive activator (co-catalyst) for ethylene oligomerization and mitigates the undesired formation of by-product polyethylene.

Abstract: High performance thin-film, transistors are entirely processed at temperatures not exceeding 150° C., using amorphous multi component dielectrics based on the mixture of high band gap and high dielectric constant (K) materials. The sputtered or ink jet printed mixed dielectric materials such as Ta2O5 with SiO2 or Al2O3 or HfO2 with SiO2 or Al2O3 are used. These multicomponent dielectrics allow producing amorphous dielectrics to be introduced in high stable electronic devices with low leakage currents, while preserving a high dielectric constant. This results in producing thin film transistors with remarkable electrical properties, such as the ones produced based on Ga—In—Zn oxide as channel layers and where the dielectric was the combination of the mixture Ta2O5:SiO2, exhibiting field-effect mobility exceeding 35 cm2 V?1 s?1, close to 0 V turn-on voltage, on/off ratio higher than 106 and subthreshold slope below 0.24 V dec?1.

Abstract: The present invention provides low profile, thick (“stubby”) longitudinal fins having a cross section which is a parallelogram, trapezoid or a triangle extending from 10% to 100% of a coil pass and comprising from 3 to 45 weight % of a coil in a radiant section of a furnace for thermally cracking one or more of paraffins and naphtha. The fins provide an additional surface through which heat may be transferred to the coil making the coil more efficient reducing greenhouse emissions.

Abstract: A method and system are presented for monitoring a process sequentially applied to a stream of substantially identical articles by a processing tool, so as to terminate the operation of the processing tool upon detecting an end-point signal corresponding to a predetermined value of a desired parameter of the article being processed. The article is processed with the processing tool. Upon completing the processing in response to the end-point signal generated by an end-point detector continuously operating during the processing of the article, integrated monitoring is applied to the processed article to measure the value of the desired parameter. The measured value of the desired parameter is analyzed to determine a correction value thereof to be used for adjusting the end-point signal corresponding to the predetermined value of the desired parameter for terminating the processing of the next article in the stream.

Abstract: A composite armor plate includes a fracture layer placed adjacent to a ceramic layer. The ceramic layer provides a ballistic resistant layer that receives a ballistic impact and propagates a compression wave. The fracture layer is placed behind the ceramic layer and absorbs a portion of the compression wave propagating out in front of the ballistic impact. The absorbed compression wave causes the fracture layer to at least partially disintegrate into fine particles, which dissipates energy in the process. To cause a higher degree of fracturing (and thus larger dissipation of compression wave energy) the fracture layer includes a plurality of resonators embedded in a fracture material.
