Abstract: A multigrade lubricating oil composition with enhanced anti-wear properties for use in an internal combustion engine comprises (a) a base oil comprising at least 90% by weight of the base oil, of one or more basestocks selected from the group consisting of base stocks derived from Fischer-Tropsch synthesised, waxy, paraffinic hydrocarbon material by processes comprising hydrocracking and/or hydroisomerisation, Group II basestocks, Group III basestocks and mixtures thereof; (b) one or more dispersant viscosity modifiers in a total amount of 0.15 to 0.8% by weight of the composition; (c) one or more dispersants in a total amount of active dispersants of 1.5 to 3% by weight of the composition; (d) one or more detergents; and (e) one or more metal dihydrocarbyl dithiophosphates.

Abstract: Smooth, preferably variable-sweep fluid collection device surfaces disposed into opposition with wind, river, surf, ocean or tidal currents generate enhanced velocity fluid flows at length driven into onboard work-extracting disc turbines at advantageous angles of attack. Keyed to shafts turning freely through optionally extendable volutes, disc turbines comprising a dense population of smooth, axially fixed or adjustably spaced discs conducting preferably laminar flow between adjacent elements develop significant torque through boundary layer adhesion and viscous shear-stress between fluid layers. Exhaust of disc turbine throughput into divergent channels drafting into external currents of initially higher than ambient velocity and lower pressure may reduce turbine discharge backpressure, rapidly clear system throughput, and allow normally disadvantageous drag to be utilized to develop greater work generation.

Abstract: Apparatus and method for adding one or more additives to an engine lubricant, whilst the lubricant is circulating within an engine having an engine lubricant filter with a by-pass valve which opens when the pressure of the lubricant passing through the filter exceeds a pre-determined back-pressure value in which the apparatus further comprises an additive chamber containing one or more additives operably connected to the by-pass valve such that when the by-pass valve opens at the pre-determined back-pressure, at least some of the lubricant is caused to flow through the additive chamber and contact the one or more additives.

Abstract: A device, system, and method are directed towards determining a suggested characteristic for an event. At least two events are determined. In one embodiment, at least one characteristic is determined for one of the event. A plurality of other characteristics is determined for the other event. The characteristics of the two events may be determined implicitly from communications during the events or from user input. Based on a relationship between the determined characteristics, the suggested characteristic for the event is then determined. In one embodiment, the relationship is defined as a match of characteristics. The event may then be modified based on the suggested characteristic. For example, a suggested member may be invited to join the event, or the event's time, location, or name may be changed. If the other event is current or pending, the event and the other event may be combined.

Abstract: A tubular body comprises an inner hollow core and an outer casing of one or more strips of self mechanically inter-engaging helically wound material having a higher yield strength than that of the core material. Also provided is a method of forming the tubular body comprising the steps of winding the outer core onto the inner core and an end connector for use with said tubular body when said body is provided with helically extending detents on an outer surface thereof.

Abstract: A device, system, and method are directed towards determining a start and/or an end time for a spontaneous event. A mobile device user creates a group for the spontaneous event, and sends the members an invite. During the event, members share media content and/or text messages with other members. Based, in part, on a flow of media content and/or text messages between the members, a determination of a start time and/or end time of the spontaneous event is automatically performed. The start time may be based on when the group is created and/or revised when a flow rate of the media content and/or messages exceed a threshold. The end time may be based on the flow rate being less than another threshold. The location of the spontaneous event may also be determined based on a location of the member's mobile devices during the event.

Abstract: A system and method for controlling an optical light source is provided. A current source drives the light source, while the voltage across and the current through the light source is measured. The voltage and current are converted to digital signals and sent to a neural network, which generates a modeled optical output power of the light source and a modeled value of the optical wavelength. A control circuit receives the modeled optical output power and wavelength and sends a control signal to the current source to minimize the difference between the desired power output and the modeled output power. In addition, a control signal is sent to a Peltier driver to control the temperature of a Peltier cooler in order to increase or decrease the wavelength emitted by a laser diode.

Abstract: A polarization twist, space-fed, E-scan planar phased array antenna. The phased array antenna incorporates a polarization twist, space-fed architecture. A plurality of unit cells are formed wherein each cell incorporates a large plurality of phased array elements and associated phase shifters. The space-feed architecture enables 2-bit phase shifters to be employed while still producing low antenna sidelobes. The phased array elements, phase shifters, and associated control circuits for controlling the phase shifters are all preferably formed on one surface of a MMIC substrate. This further simplifies significantly the cost and complexity of manufacturing and testing the E-scan phased array antenna. The antenna can therefore be used in applications where an E-scan phased array antenna would have been too costly to employ.

Abstract: The present invention provides for a tool holder for use by fishermen, handymen and the like. The tool holder comprises a holster portion having a pocket of a size for holding a tool, the pocket being formed from a front and base connected together along the sides thereof and having an open top. The tool holder includes a belt loop portion for attaching the holder to the belt of a user. The holster portion is suspended from the belt loop portion through a moveable connection which allows the holster portion movement from front to back and side to side simultaneously. This allows the holster portion to remain suspended in a generally vertical orientation independent of the movement of the user thereby reducing the possibility of interference of the holster to freedom of movement of the user.

Abstract: Apparatus including a disintegrating head and a mixing head each having a stator and a co-operating rotor. The rotors are mounted at axially spaced locations on a common shaft and the stators are supported with the inlet to each stator facing axially of the shaft, away from the other stator. The disintegrating head has a stator formed of a plurality of stator elements arranged at angulary spaced locations on a base member. Each stator element has a cutting edge which is inclined outwardly of the element in a direction away from the base member. Associated with the disintegrating head is a shroud which serves to retain large lumps of material in the vicinity of the head.

Abstract: A mixing device comprising cooperating rotor and stator elements wherein a stator blade is arranged at the inlet to the stator element for cooperation with an axially outer end of at least one rotor blade. In use, fibrous material which is drawn into the stator element by rotation of the rotor element is shredded by the action of the cooperating rotor and stator blades. The material is then expelled radially outwardly from the stator element and is subjected to high shearing forces, which effect further mixing and disintegration, as it passes between a radially center edge of a rotor blade and the stator elements.
