Discloses novel biodegradable high performance hydrocarbon base oils useful as lubricants in engine oil and industrial compositions, and process for their manufacture. A waxy, or paraffinic feed, particularly a Fischer-Tropsch wax, is reacted over a dual function catalyst to produce hydroisomerization and hydrocracking reactions, at 700 DEG F.+ conversion levels ranging from about 20 to 50 wt. %, preferably about 25-40 wt. %, sufficient to produce a crude fraction, e.g., a C5-1050 DEG F.+ crude fraction, containing 700 DEG F.+ isoparaffins having from about 6.0 to about 7.5 methyl branches per 100 carbon atoms in the molecule. The methyl paraffins containing crude fraction is topped via atmospheric distillation to produce a bottoms fraction having an initial boiling point between about 650 DEG F. and 750 DEG F. which is then solvent dewaxed, and the dewaxed oil is then fractionated under high vacuum to produce biodegradable high performance hydrocarbon base oils.

A touch-sensitive device accepts single-touch and multi-touch input representing gestures, and is able to changing a parameter of a gesture responsive to introduction or removal of a point of contact while the gesture is in progress. The operation associated with the gesture, such as a manipulation of an on-screen object, changes in a predictable manner if the user introduces or removes a contact point while the gesture is in progress. The overall nature of the operation being performed does not change, but a parameter of the operation can change. In various embodiments, each time a contact point is added or removed, the system and method of the present invention resets the relationship between the contact point locations and the operation being performed, in such a manner as to avoid or minimize discontinuities in the operation. In this manner, the invention avoids sudden or unpredictable changes to an object being manipulated.

The disclosed textures are particularly useful as anti-reflecting covers for displays, and as directly molded anti-reflecting surfaces in eyeglass lenses. Other applications such as covers for artwork, and improved solar cells are made practical by the invention.

High performance flow batteries, based on alkaline zinc/ferro-ferricyanide rechargeable (“ZnFe”) and similar flow batteries, may include one or more of the following improvements. First, the battery design has a cell stack comprising a low resistance positive electrode in at least one positive half cell and a low resistance negative electrode in at least one negative half cell, where the positive electrode and negative electrode resistances are selected for uniform high current density across a region of the cell stack. Second, a flow of electrolyte, such as zinc species in the ZnFe battery, with a high level of mixing through at least one negative half cell in a Zn deposition region proximate a deposition surface where the electrolyte close to the deposition surface has sufficiently high zinc concentration for deposition rates on the deposition surface that sustain the uniform high current density. The mixing in the flow may be induced by structures such as: conductive and non-conductive meshes; screens; ribbons; foam structures; arrays of cones, cylinders, or pyramids; and other arrangements of wires or tubes used solely or in combination with a planar electrode surface. Third, the zinc electrolyte has a high concentration and in some embodiments has a concentration greater than the equilibrium saturation concentration—the zinc electrolyte is super-saturated with Zn ions.

A single-tilt-rotor VTOL airplanes have a tiltable rotor attached to an elongated power pod containing the collective and cyclical pitch mechanism, and transmission. The power pod is pivotably attached to a base that is slidably mounted on a pair of slotted guide beams attached on top of the roof of the fuselage. The guide beams run longitudinally from the front of the aircraft to past the center of gravity (CG) of the aircraft in order to transport the power pod from the front section to the center section when converting from the horizontal cruising mode to the VTOL mode. In the horizontal cruising mode, the power pod perched horizontally on top of the fuselage front section with sufficient clearance for the rotor to rotate in front of the aircraft. Upon transitioning to the VTOL mode, a telescopic actuator is used to pivot the power pod vertically while a cable-winch system is used to move the entire power pod and base assembly rearwardly to stop at the center of gravity of the aircraft, and vice versa, thus allowing the power pod to travel significantly rearward and forward as required for proper balancing of vertical lift as the power pod pivots 90 degrees during transition from VTOL mode to the cruising mode. A single piston engine, or a single or pair of turbofan engines, mounted slightly to the rear of the CG, have drive shafts that can be clutched and mated onto respective receiving shaft from the transmission within the power pod in order to power the tiltable rotor. The engine is also attached to a propeller for horizontal propulsion, or if turbofan engines are used, jet thrust is generated for horizontal cruise. A small anti-torque rotor or ducted fan toward the tail of the aircraft is mechanically coupled to the engine via a drive shaft to provide the necessary side-way thrust to overcome the main rotor's torque. In the horizontal cruising mode, the tiltable rotor is allowed to windmill slowly at a minimum rotational speed necessary to maintain the integrity of the rotor blades. The same propulsion principle can be applied to VTOL airplanes having more than one tiltable rotor, thereby can potentially increase the speed, range and reliability of current twin-wing-mounted-tilt-rotor aircraft. A pair of high-aspect-ratio wings on both sides of the fuselage provide highly efficient lift during cruising flight with very little induced drag. Conventional horizontal and vertical tail planes are used for directional stability in the cruising mode.

A system and method for protecting against spam messages. An incoming filtering message system receives an anti-spam policy configuration message and forwards the message to a trusted environment, such as a smart card. The configuration is forwarded to the trusted environment over a secure channel, such as an encrypted tunnel. An anti-spam filter is created based upon the message. Upon receiving a potential spam message at the apparatus, the incoming filtering message system retrieves at least one of the created anti-spam filters and applies the anti-spam filter to parameters of the potential spam message. If after applying the filter, it is determined that the potential spam message is an actual spam message, the actual spam message is either sent to a junk folder and later deleted or immediately deleted. Alternatively, a user of the apparatus may be queried to confirm that the potential spam message is an actual spam message.

A DQPSK optical signal is split by the splitter 1 into Data 1 and Data 2 systems. For each system, a phase-modulated optical signal is converted into an intensity modulated electric signal, and clock reproduction and data reproduction are independently carried out for each system. While a phase difference occurs between the data of each system, a clock signal having an intermediate phase of the reproduced clock of each system is generated to latch data of both systems by using the clock signal. This results in the data of both systems having the same phase.
