Abstract: The engine lubricating system can become contaminated with carbon deposits and sludge. Sludge is where the combustion by-products that have entered the oil base saturate this oil base, thus forming a thick carbon rich substance. Sludge is not wanted within the engine. Sludge and or carbon deposits in the motor oil cause problems. Such carbon deposits form in the motor oil from heat, pressure, and namely combustion gases that have leaked pasted the piston rings. Turpentine and terpenes, hereafter referred to as “terpenes”, have shown that these chemicals can breakdown carbon which has been deposited within the engine's oil base.

Abstract: Porous media containing undesired substances, e.g., perfluoroalkylated substances, are treated by mixing the porous media with a solid fuel comprising organic material. The mixture is heated to 200° C. to 400° C. to initiate smoldering combustion and an oxidizer gas is forced through the heated mixture such that the smoldering combustion is self-sustaining until the mixture reaches a PFAS destructive temperature and the perfluoroalkylated substances are thermally destroyed. A system is provided for conducting the treatment. The system includes a source of wax, wood chips, sawdust, tire scraps, waste rubber compounds, coal, granular activated carbon, solid fat, and combinations thereof as solid fuel. A mixer is provided for mixing the porous media with the solid fuel. An ignition system including static heating elements and a gas blower are provided for forcing heated oxidizer gas through the mixture such that self-sustaining smoldering combustion of the mixture is initiated and sustained.

The yoke further is configured to rotate the primary and secondary mirror about a third axis. The secondary mirror is configured to move from a stowed position in which the optical assembly is positioned to receive an image from a field of view to a deployed position in which the optical assembly is positioned to receive an image from a field of regard.

Abstract: The testing of various chemicals has yielded new chemicals and chemical mixtures for the use of removing carbon deposits from the internal combustion engine. Some of these chemicals and chemical mixtures have proven to work better across many different carbon types than other chemicals that were tested. These chemical terpenes are typically produced from plants. One standard terpene mixture is known as turpentine. The chemical turpentine and chemicals found in turpentine have been determined, through our research and testing, to be extremely effective at removing the carbon that is produced within the internal combustion engine.

Abstract: Examples of the present disclosure relate to techniques for headlamp heater control. In examples, a headlight assembly comprises a heater, which is used to prevent or remove condensation/precipitation on a lens of the headlamp assembly. Given it may be difficult for an individual to know when to manually turn the headlamp heater on, an electronic control unit (ECU) may evaluate a set of rules to determine when to automatically enable or disable the headlamp heater. The rules may be associated with atmospheric conditions outside the vehicle, the state of the vehicle (e.g., whether windshield wipers are turned on, whether windshield defog is enabled, whether a mirror heater is turned on, etc.), and/or user input received by an ECU of the vehicle, among other examples.

Abstract: Detecting a leak from a site in a sealed system with a source of pressurized gas which is capable of passing through the site, a composition of matter which adheres to the surfaces of the system and which is capable of showing the presence of the gas escaping from the site. The method includes: injecting gas into the system to a pressure in excess of the surrounding pressure, and covering the external surface with the composition to identify the location of the site by the interaction of the escaping gas with the composition. The composition is foam that includes a surfactant which forms a least one bubble in the presence of escaping gas and an indicator which changes color in the presence of the escaping gas. The leak is an opening down to at least the size of a hole 0.001? in diameter. A gas detector may also be used.

Abstract: This invention relates to compositions of matter formulated to work in conjunction with CO2 gas for identifying the exact leak site location of small and large leaks in sealed systems. The leak finding compositions of matter foam, or are in the form of a foam, when applied to the one or more external surfaces of a system, that is closed and pressurized with CO2, where a leak site location is suspected. This foam then changes color from a first color to a second color over the exact leak site.

Abstract: At times, it may be desirable to determine that a client system is, or to determine the number of client systems that are, presenting particular dynamic content when an auditable event occurs in the dynamic content. One manner of making the determination may include accessing presentation time information that indicates the time(s) at which one or more client systems present particular dynamic content and accessing event time information indicating the time(s) at which one or more auditable events occur in the dynamic particular content. Based on the presentation time information and the event time information, it may be possible to determine that a client system is, or to determine the number of client systems that are, presenting particular dynamic content when an auditable event occurs in the dynamic content.

Abstract: This invention relates to cleaning the induction systems, the combustion chambers and exhaust systems of internal combustion engines. And, more particularly, to chemicals and mixtures of chemicals for removing the different types of carbon deposits encountered in internal combustion engines used in “road vehicles”. Carbon deposits were taken from the induction systems of these road vehicles for the purpose of bench testing such carbon and product development. More specifically, chemicals (i.e., solvents) and chemical mixes (i.e., solutions) have been accurately tested on such harvested carbon deposits for their ability to remove the various types of carbon deposits that accumulate within road vehicle internal combustion engines. Additionally this invention also relates to apparatus for delivering chemicals and chemical mixes.

Abstract: Described is a linear conveyor for advancing vehicles through a vehicle washing system. The linear conveyor includes a pair of reciprocating platforms having a plurality of counterweighted and pivotally connected pawls. The pawls are biased such that they are angled upwards and in a forward direction at rest. Alternating motion of the reciprocating platforms causes a vehicle to move forward along the linear conveyor by pressing the pawl into the rear of the tire in a forward motion, while a rearward moving reciprocating platform slides underneath the tires of the vehicle on an opposite side of the vehicle.

Abstract: The present device is an electronically controlled safety system for use in firearms, comprising a shape memory actuator configured to connect a mechanical locking interface to a trigger mechanism interface comprising a point of connection to a firearm's trigger mechanism. This shape memory actuator can be controlled by use of an authentication system comprised of an RFID module and a control module. The user of the firearm can provide authorization to place the firearm in the armed position by placing an RFID tag having an activation code near the RFID module, which can then activate the shape memory actuator through the control module. When the mechanical locking interface is connected to the trigger mechanism interface a firearm's trigger mechanism is locked in place and the firearm is in a safe position and when the mechanical locking interface is not connected to the trigger mechanism is in an armed position.
