Abstract: A discharge cut-off valve for an air compressor is provided. The discharge cut-off valve includes a hinged leaf valve within the recessed portion of a cylinder head manifold. The hinged leaf valve is rotatably anchored at a first end to a joint pin and is guided at a second end by a guide pin. In the on-load phase, the hinged leaf valve is seated over an unloader vent opening while a discharge vent opening is uncovered. In the off-load phase, the hinged leaf valve is seated over the discharge vent opening while the unloader vent opening is uncovered. As a result, compressed air is prevented from escaping the discharge port of the air compressor during the off-load phase, obviating the need for a down-stream turbo cut-off valve in an air dryer, for example.

Abstract: A system for the identification and subsequent rating of domains based on a result derived from a proprietary algorithm configured to detect when a new domain is registered, correlate the domain to registrant data, cross-check the data based on domain proximity to known-malignity, and output a proximity score employed to convey the potential for malicious content or intentions available or to be served as content accessible via the domain. The system is equipped with a dynamic domain database configured to provide near-real-time domain registration data across all domain extensions, facilitating the detection and scoring of new domains as soon as practicable after their inception. Domains are routinely re-evaluated for score consistency, helping to better maintain the security of visitors to websites hosted, or automated connections to infrastructure present on the domain.

Abstract: A compressor for a vehicle air supply system includes a manifold, a cover, a gasket, an inlet, and an outlet. The manifold and cover are fixedly stacked together, and define a fluid channel system between them. The gasket extends laterally from between the manifold and cover. The fluid channel system includes an inlet air passage extending from the inlet to a cylinder inlet, a discharge air passage extending from a cylinder outlet to the outlet for discharging compressed air to the outlet, and one or more coolant channels that can be fed with a coolant to cool at least the discharge air passage. The inlet air passage, the discharge air passage, and the coolant channel(s) extend laterally, defined by wall faces of the discharge air passage. The wall faces comprise turbulator fins protruding into the discharge air passage. The turbulator fins create turbulence in the discharged compressed air flow.

Abstract: A pressure monitoring device for use in an air system of a vehicle and for controlling a compressor comprises an input air connector for connection to an air tank and for receiving an input pressure from the air tank. A first signal air connector can output a pneumatic ON-load signal for adjusting the compressor to an operation mode. A second signal air connector can output a pneumatic OFF-load signal for adjusting the compressor to a non-operation mode.

Abstract: A cylinder head for a compressor includes a closure device that can be adjusted between an unactuated position (off-load) in which the compressor delivers air and an actuated position (off-load) in which the compressor is running in an idle mode, a pneumatic control device having a control cylinder and a control piston that can be moved in the control cylinder, a spring device that prestresses the closure device into the unactuated position (on-load), and a driver configured to couple the control piston to the closure device. The closure device closes a compressed air passage in the unactuated position (on-load) and clears the compressed air passage in the actuated position (off-load), and the driver is permanently connected to the closure device and can be driven by the control piston.

Abstract: A method and kit for game hunters to track the blood trail of wounded game at night using an ultraviolet light comprising (i) a portable electric powered light that emits a beam of light in a distinct ultraviolet electromagnetic wavelength range and (ii) eyeglasses with colored lenses to look through to dampen glare and reflection of the ultraviolet light off the terrain. The method comprises of shining the ultraviolet light and lluminating the terrain area suspected of having blood. The blood that is present will absorb the blue ultraviolet light and turn darker making it easier for a hunter to follow the blood trail left by the wounded animal so that it may be recovered.
