An electronic device comprises a touch screen and is configured to enter a lock state upon the fulfilment of a predetermined condition. The device is configured to display one or more images on the touch screen when the device is in the lock state, of which images one or more includes at least one predetermined point. The device is further configured to detect a touch on a predetermined point in one or more images and to deactivate the device lock state upon detection of a predetermined number of touches on successive images including a predetermined point.

Methods and systems for hydroprocessing heavy oil feedstocks to form an upgraded material involve the use of a colloidal or molecular catalyst dispersed within a heavy oil feedstock, a hydrocracking reactor, and a hot separator. The colloidal or molecular catalyst promotes hydrocracking and other hydroprocessing reactions within the hydrocracking reactor. The catalyst is preferentially associated with asphaltenes within the heavy oil feedstock, which promotes upgrading reactions involving the asphaltenes rather than formation of coke precursors and sediment. The colloidal or molecular catalyst overcomes problems associated with porous supported catalysts in upgrading heavy oil feedstocks, particularly the inability of such catalysts to effectively process asphaltene molecules. The result is one or more of reduced equipment fouling, increased conversion level, and more efficient use of the supported catalyst if used in combination with the colloidal or molecular catalyst.

The present invention is a process for transalkylating aromatic hydrocarbon compounds, the process comprising introducing an aromatic hydrocarbon feed stream into a transalkylation zone to yield high-purity benzene as a byproduct while meeting transalkylation objectives. The feed stream contacts a catalyst in the transalkylation zone under conditions adjusted to control benzene purity as well as transalkylation performance.

With devices and methods for reducing the contamination of a sensor, a sensor or sensor element—preferably a hot film air-mass meter—is deactivated when a software function integrated in the electronic control unit detects a possible contamination or a media carry-in. The sensor is deactivated using a high-side switch in the voltage supply or a low-side switch in the ground connection, wherein the media carry-in detection and the switch control are carried out by the control unit or an evaluation unit in the sensor. After the sensor is deactivated, a substitute signal is optionally generated that replaces the missing output signal of the sensor.

In a particular embodiment, a method includes modifying an output impedance associated with the input receiver. In response to modifying the output impedance, the method restricts an output voltage at an output node of the input receiver. Particular embodiments of an input receiver circuit are also disclosed.

Shown is a latch pin for use in a valve lifter and a valve lifter including the same. The latch pin for selectively latching within a pin chamber provided in the valve lifter is configured as a whole as a cylindrical pin with one end in the shape of a spherical crown, wherein a stepped flat is formed on radially one side of said one end and is dimensioned to be received within the pin chamber to engage with an axial latching surface thereof. On the top side of said one end, a first relief is formed by beveling the spherical crown, and on the radially other side opposite to the stepped flat across said first relief, a second relief is formed by beveling the spherical crown, wherein the second relief radially adjoins the first relief and circumferentially adjoins a remaining pin face in the shape of the spherical crown.

The present invention relates to a method of preparing an aromatic compound from acetylene, which includes synthesizing an aromatic compound from an acetylene-containing reactant gas in the presence of a zeolite catalyst for the aromatization of acetylene, and subjecting the zeolite catalyst deactivated by the coke formed in the aromatization of acetylene, to plasma treatment at ambient temperature and pressure so as to selectively remove the external cokes and partial internal coke, thereby regenerating the zeolite catalyst; a method of regenerating the zeolite catalyst used in the aromatization of acetylene by plasma treatment; and a regenerated zeolite catalyst for the aromatization of acetylene, prepared thereof.

This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B®), nitric acid, acetic acid and / or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.
