Abstract: A lunchbox having a base part (2) having a food cavity (40) for receiving food; a lid (1) sealingly, closing the base part (2); and a closure (3) for closing the lunchbox. The closure (3) has at least one locking element. At least one lifting-element clamp (30, 31) is provided, which lifts the lid (1) from the base part (2.) when the locking element is in a position in which it is moved with respect to a closed position. Preferably the locking element and the lifting element are a single component formed by a clamp. This lunchbox is suitable for transporting, storing and preparing meals by optionally heating and steaming the food. The lunchbox allows safe opening of the lid without the risk of scalding the user and also ensures optimal sealing.

Abstract: A portable lunchbox (1) for storing, transporting and preparing food, comprising a food cavity (10) for receiving food; a heating cavity (20) for receiving water; a heating element (80) for heating water in the heating cavity (20); a switch device (50) which can be switched from a first state to a second state; wherein the lunchbox (1) is designed in the first state of the switch device (50) to heat food arranged in the food cavity (10), and in the second state of the switch device (50) to steam food arranged in the food cavity (10). This lunchbox enables various kinds of meals preparation in a simple manner.

Abstract: A quadric reflector can have an approximately conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror can be positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the quadric reflector into the aperture or reflect light emitting from the aperture onto the quadric reflector. The overhang enclosure can have a substantially conical shape which eliminates secondary reflection resulting from the environmental light reaching the aperture twice. Using the overhang enclosure to absorb the secondary reflection eliminates or minimizes banding.

Abstract: A composition and a process for straightening hair are disclosed. The process includes coating keratin fibers with a composition comprising a thermally-activated agent and a guanidine moiety containing adjuvant compound and contacting the coated keratin fibers with a heating device at a temperature of at least 185 C for sufficient time to modify the keratin fibers.

Abstract: A process for recovering ethanol obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and ethyl acetate and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. The ethanol product is recovered from the residue stream.

Abstract: The present invention is directed to processes for recovering ethanol obtained from the hydrogenation of acetic acid. Acetic acid is hydrogenated in the presence of a catalyst in a hydrogenation reactor to form a crude ethanol product. The crude ethanol product is separated in one or more columns to recover ethanol. In some embodiments, less than 10 wt. % ethanol is recycled to the hydrogenation reactor.

Abstract: In one embodiment, the invention is to a process for producing multi-carbon alcohols, including butanol and/or hexanol. The process comprises the step of reacting ethanol in a reactor to form a crude product comprising butanol, ethanol, and water. The process further comprises the step of separating at least a portion of the crude product in a first distillation zone to form a first distillate comprising ethanol and a first residue comprising butanol, and water. The process further comprises the step of separating at least a portion of the first residue in a second distillation zone to form a second distillate and a second residue comprising butanol.

Abstract: A process for recovering ethanol obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and ethyl acetate and a residue stream comprising ethanol, acetic acid and water. Acetal byproduct can be reduced or removed through configurations of hydrolysis secondary reactors. The ethanol product is recovered from the residue stream.

Abstract: A process for producing ethanol and, in particular, to a process for reducing the concentration of acetic acid in a crude ethanol product by esterifying unreacted acetic acid with an alcohol.

Abstract: A process for recovering ethanol obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and ethyl acetate and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. Unreacted acetic acid can be reduced or removed through configurations of esterification secondary reactors. The ethanol product is recovered from the residue stream.

Abstract: An embodiment of the invention is directed to retaining customers for a wireless-service provider (“carrier”). A ratio is calculated based on a number of incoming calls received by a mobile device and a number of outgoing calls originating from the mobile device. The ratio is also based on locations of callers that originated the incoming calls. The ratio is compared to an influencer threshold. When the ratio is greater than the influencer threshold, then a subscriber associated with the mobile device is indicated to be an influencer that potentially affects decisions of other subscribers regarding whether to cancel or maintain their subscriptions with the wireless service. An incentive is provided to the influencer to increase the likelihood that the influencer will retain a subscription with the wireless service, thereby increasing the likelihood that other subscribers who might be influenced by the influencer will retain their respective subscriptions.
