Abstract: An automatic variable gain amplifier is provided. The automatic variable gain amplifier automatically adjusts the amplification of a signal, and in one embodiment, an ion signal, based on the amplitude of the peaks of the signal. The automatic variable gain amplifier detects the peaks of the signal, compares them to a threshold value, and, based on this comparison, varies the amount by which the signal is amplified. The automatic variable gain amplifier produces a composite output waveform for an input waveform with an amplitude that may vary over a plurality of orders of magnitude.

The paint roller paint saving pan is configured to provide access to the roller pad by a rigid tool to scrape excess paint therefrom.

Abstract: Disclosed is a method of manufacturing a glycerol carbonate (GC). The method includes a bio-catalyst reaction for generating the GC and byproducts generated by reacting a reactant solution using a lipase of a bio-catalyst. In this instance, the reactant solution is prepared by adding glycerol, a glycerol-containing composition, or a dimethyl carbonate (DMC) in a reaction solvent.

Abstract: A method and apparatus for sensing particulates within an exhaust flow are provided. The methods and apparatus utilize a soot sensor that includes opposed electrodes separated by an insulator. Preferably, a gap is formed between the electrodes and the insulator to prevent electrical current from flowing therebetween. The soot sensor, when positioned in an exhaust flow, will accumulate a layer of particulates on an outer surface thereof. As the layer of particulates increases the particulates will bridge the two electrodes permitting current flow. The sensor is configured with a proper geometry and potential difference between the electrodes to generate currents in the milli-amp range. Further, the sensor is configured to have a regenerative effect that causes the bridge to be broken when particles sees to impinge the soot sensor.

Abstract: A yoke type quick opening closure is provided. A torque bolt shares loads of the yoke with a drawbolt, and a separate safety bolt is provided. A common wrench interface feature is also provided.

Abstract: A fuel delivery and control system is provided including a dual pump fluid circuit configuration comprising a fixed positive displacement pump sized to supply the main engine burn flow ranging from above windmill through cruise, a positive displacement actuation pump including a variable pressure regulator, wherein the actuation pump is sized to supply fluid to engine actuators, valves and other hydraulically operated engine components and a pump flow sharing system interconnecting the two pumps. The combined flow from the two pumps is sufficient to meet the engine flow demand for windmill relight and maximum flow conditions. During cruise or normal operating conditions, the pumps operate in completely isolated flow circuits, minimizing recirculation and therefore heat input into the fuel supply system.

Abstract: The present invention relates to a device for introducing a liquid into a gas flow, more preferably for an exhaust system of an internal combustion engine. The device includes a chamber, an injection device and a channel. The channel with a circumferential region of an inlet section protrudes into the chamber and there on an inner side facing the gas flow has a surface. Said surface is arranged offset to the inside with respect to a channel profile. The proposed design results in improved evaporation of the liquid introduced into the gas flow.

Abstract: A dental prosthesis removal tool includes a handle portion and a top portion, the top portion including a head portion and a beak portion. The beak portion is configured to engage both a maxillary dental prosthesis and a mandibular dental prosthesis without the tool needing to be reoriented. The dental prosthesis removal tool makes it possible for a dental prosthesis wearer to remove dental prostheses without the user placing his or her fingers inside of his or her mouth. The dental prosthesis removal tool also allows a denture wearer to remove dental prostheses without bending, work hardening, or breaking metal clasps contained in some dental prostheses. The dental prosthesis removal tool further allows a denture wearer to more comfortably remove his or her dental prosthesis, promoting better patient compliance with maintenance procedures and oral hygiene.

Abstract: An apparatus that prevents collapse mode and sling-shot mode of the accumulated air spring vibration isolation system is presented. The apparatus is contained in an air spring which is connected to accumulator. The apparatus blocks air flow to the accumulator when the air spring is attempting to bottom out, resulting in a soft pneumatic stop for the suspended mass. High pressure air within the air spring at its lowest height is evacuated to the accumulator, thus precluding a “sling shot” reaction of the suspended mass. The apparatus incorporates a double acting air cylinder with an orifice disk attached to a piston shaft end and an orifice contained within the air spring head. The upper air cylinder volume is vented to the air spring interior compartment through an unrestrictive orifice and the lower air cylinder volume is vented to the high pressure source through a highly restrictive orifice.

Abstract: A forced return solenoid that includes an electrical winding configured to create an electromagnetic field when electrical current flows through the winding, an electrical terminal configured to be connected to a source of electrical energy, and a moveable contact plate configured to be moved into contact with the electrical terminal. Embodiment of the forced return solenoid include a plunger configured to move axially in response to the electromagnetic field generated by the electrical winding. Movement of the plunger in one direction causes the moveable contact plate to connect with the electrical terminal. Movement of the plunger in the opposite direction causes an impact intended to break the connection between the moveable contact plate and the electrical terminal. Embodiments of the forced return solenoid further include a return spring configured to move the plunger in the second direction, wherein the impact means comprises a removable snap ring affixed to the plunger.

Abstract: A flow rate meter that includes a container of known and fixed volume. Electrodes, or sensors, are placed inside the container at several different heights. An electronic circuit uses the electrodes, or sensors, to measure the time it takes this container of known and fixed volume to fill a certain distance with water or water-based solution. The electronic circuit calculates the flow rate in engineering units from this elapsed time by knowing the volume of the container between the fixed electrodes.
