Abstract: A fire exposure protection sprinkler assembly includes a fluid supply line configured to provide fire exposure protection fluid and a fire exposure protection sprinkler. The fire exposure protection sprinkler includes a body coupled to the fluid supply line and configured to receive the fire exposure protection fluid, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow, a housing having a pair of legs arranged opposite the housing of each other and having an aperture, and a deflection assembly having a pair of guide pins coupled to a deflector and the housing and disposed within each of the apertures of the legs, wherein the deflection assembly is configured to extend from the housing, wherein the deflection assembly is configured to receive the flow of the fire exposure protection fluid while extending from the housing.

Abstract: A sprinkler system includes a fitting, at least one tube, at least one fluid distribution device, and an actuator. The fitting connects with at least one pipe, defines an opening, and includes a seal. The seal has a closed state in which the seal seals the opening and an open state in which the seal does not seal the opening to allow fluid flow from the at least one pipe through the opening. The at least one tube connects with the fitting on an opposite side of the seal from the at least one pipe. The fluid distribution device is connected with the at least one tube. The actuator receives a detection signal indicative of a trigger condition and causes the seal to change from the closed state to the open state to allow the fluid flow through the opening responsive to receiving the detection signal.

Abstract: Systems and methods described herein are directed to a sprinkler to provide fire protection. The sprinkler system can include a deflector portion, a head portion, a thermal trigger portion, a trigger seat, or a tubular outer structure. The tubular outer structure can define an internal water flow channel. The water flow channel can extend along a longitudinal axis between an inlet and an outlet. The trigger seat can include a tubular exterior. The tubular exterior can be coupled with the tubular outer structure. The trigger seat can include a component. The component can occlude a flow of fluid through the dry pendent sprinkler assembly. The component can maintain the thermal trigger portion in position. At least one portion of the tubular exterior of the trigger seat can protrude into the water flow channel at an angle towards the longitudinal axis.

Abstract: A fire exposure protection sprinkler assembly provides fire exposure protection for one or more windows and includes a fire exposure protection sprinkler, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow from the fire exposure protection sprinkler, and a housing having a pair of legs, with each of the legs having an aperture. The assembly also includes a deflection assembly configured to extend from the housing due to gravity and activation of a cover plate, with a deflector configured to disperse the fire exposure protection fluid over the one or more windows so as to wet the one or more windows.

Abstract: There is provided a system and mechanism for substantially reducing or substantially eliminating vibration or noise of a doctor blade of an image forming apparatus during operation. The system and mechanism provided includes at least one contact in communication with a doctor blade surface, e.g., a front surface, to substantially reduce or substantially eliminate vibration and/or noise associated with a doctor blade during image forming.

Abstract: A magnetic roller for electrophotography comprises a foamed resin magnetic material. A method of producing a magnetic roller comprises the steps of providing magnetic filler, a resin binder and a foaming agent in a closed mold; activating the foaming agent in the closed mold; and removing the resulting formed roller from the mold.
