Abstract: A pendent residential fire prevention sprinkler has a frame structure extending from the sprinkler body, and a system for blocking an outlet to prevent fluid from passing through the outlet until occurrence of a predetermined condition and for unblocking the outlet in response to occurrence of the condition. A deflector is supported by the frame structure at a predetermined distance from the outlet, at a position to be impinged upon by the fluid leaving the outlet. The deflector has a central portion and a peripheral portion, and slots formed in the periphery, defining tines therebetween. The slots include a first plurality of slots, each of which extends inward from the deflector periphery with a uniform width, a second plurality of slots, each of which has a first portion and a second portion between the deflector periphery and the slot's closed end, where the first portion has a width that varies at different points, while the second portion has a uniform width.

Abstract: A selectable detent relief valve of this invention is used to operate a hydraulic detent mechanism on a manually operated spool valve. This design has three modes of operation, no-detent, continuous detent and kick-out detent. The no-detent position allows flow to pass through the relief valve, from a first port to a second port and bypass the relief function. The pressure created, disengages the detent mechanism in the spool valve. The spool always returns to neutral position as long as pressure is present. The continuous detent position blocks the flow from a first port to a second port. The kick-out detent position allows flow to pass from the first port to the second port to override (kick-out) the detent mechanism in the spool when the pressure is greater than 2600 psi.

Abstract: Positioning assembly for positioning a sensor in a body having an environment contained therein. The assembly includes generally-annular adapter and fastening members. The adapter member is provided as extending intermediate an upper first end and a lower second end, and further as having an inner surface configured for a threaded engagement with an externally-threaded terminal portion of the sensor, and an outer surface including a bearing portion. The annular fastening member has an inner surface receivable coaxially over the outer surface of the adapter member and an outer surface configured for a threaded engagement an opening formed within a wall of the body. With the fastening member being received over the adapter member and the adapter member being threadably engaged with the sensor terminal portion, the fastening member is threadably engagable with the body wall opening for movement into an abutting, force-transmitting contact with the bearing portion of the adapter member.

Abstract: A ball valve has a body with a cylindrical bore extending axially inwardly from the exterior of the body and defining a valve chamber. Inlet and outlet passages extend from the exterior of the body inwardly to the chamber. A ball valve member is disposed within the chamber and has an operating stem extending axially within the chamber to a position exterior of the body. A mass of packing material surrounds said ball valve member and substantially fills a portion of the chamber. The packing material initially has a smooth cylindrical outer configuration which matches the cylindrical surface configuration of the chamber. The body further includes a plurality of splines extending axially along the interior surface of the chamber. A flat washer and a packing ring are located around the operating stem of the ball the valve member, and a packing nut applies a bias force through the washer to the packing.
