Lidded vessel made from resilient plastics for laboratory use with a tubular vessel which has a vessel base at one end, a vessel opening at the other end, a retaining region on the inner wall of the vessel and an insertion region between the vessel opening and the retaining region, a lid which has a lid base and a stopper on one side of the lid base and which may be inserted through the vessel opening into a sealing position in the vessel, in which a sealing region of the stopper is placed on a sealing seat on the inner wall of the vessel, and a sliding ring and a retaining ring on the periphery of the stopper, the sliding ring having a lower coefficient of sliding friction relative to the insertion region than the retaining ring has relative to the retaining region and, when mounted, slides over the insertion region and is placed in the sealed position of the retaining ring on the retaining region.

A circular parachute includes a circularly shaped canopy having a skirt band and a plurality of cascaded, Y-shaped main suspension lines connected to the skirt band that converge downwardly to a suspension line junction. Each main suspension line includes a lower segment that branches into at least two upper segments. One embodiment includes a canopy with a vent band and Y-shaped vent suspension lines that converge downwardly to a vent centerline. A generally planar reefing device for slowing the opening of the canopy defines a plurality of openings through which the main suspension lines extend. In one reefing device embodiment, a strip of material (e.g., a nylon strap) is folded into multiple strip segments arranged in a five-point star configuration. Eyelets in the form of brass grommets extending through the strip segment junctions form suspension-line-receiving openings.

A locking device for a leaf pivotally mounted in a frame, the leaf having a leading face, a trailing face, a bottom edge and side edges, and being pivotally moveable relative to the frame between an open position and a closed position, the locking device comprising at least a first cam rotatable between an unlocked condition and a locked condition, the plane of rotation of the cam being perpendicular to the plane of the leaf when in the closed position, wherein in the locked condition the cam is engageable with a cam engaging surface on the leaf or the frame, engagement of the cam with the cam engaging surface preventing the leaf from moving away from the closed position.

An aircraft door mechanism includes a solenoid connected to a support assembly. The solenoid displaces the latch pin between a solenoid energized and a solenoid de-energized position. A catch assembly rotatably connected to the support assembly is positioned to engage a 3-½ degree or less taper portion of the latch pin in the solenoid energized position. When the latch pin moves to the solenoid de-energized position, a latch bolt supported by the door rotates the catch assembly. The latch bolt includes a distal bulbous end which multiplies the force applied to the door to rotate the catch assembly. If the latch pin is extended, a substantially greater force is required to force the latch pin to the solenoid de-energized position owing to the reduced taper of the latch pin. Authorized door entry is therefore easier and unauthorized door entry is made more difficult.

The invention belongs to the technical field of valve equipment, and in particular, relates to a right-angled manual valve based on a pilot structure. The right-angled manual valve comprises a valve body, wherein a valve cover is fixedly mounted above the valve body; a support frame is fixedly mounted above the valve cover; the internal of the support frame is in threaded connection with a pilot rod; a rotating handle is mounted at the upper end of the pilot rod through a thread; a locking nut is in threaded connection between the pilot rod and the rotating handle; the pilot rod and the valve core are matched and provided with a pressure plate; the other end of the pilot rod is in threaded connection with a pilot valve core; the external of the pilot valve core is matched and provided with a valve core closing plug; the external of the valve core closing plug is in threaded connection with a valve core; a feed port is formed in one side, far from the valve core, of the valve body; and a discharge port is formed below the valve core. The valve adopts the pilot structure, can realize quick opening, is low in opening torque, and largely prolongs the service life.

The invention relates to an easy-opened environmental-protection oral liquid packaging bottle which comprises a bottle body and a bottle cover, wherein the bottle body comprises a bottle body and a bottle opening, the bottle cover is installed on the bottle opening in a sealing way through an inner barrel, anti-theft clamping platforms which are buckled with each other are respectively arranged at the inner surface of the bottle cover and the outer surface of the bottle opening of the bottle body in a corresponding way, the bottle is made of plastic materials, a horn-shaped opening is arranged at the bottom of the bottle cover, the diameter of the lower opening of the horn-shaped opening is slightly larger than the bottle body, two sides of the bottle cover are symmetrically provided with vertical thin-wall guide opening grooves, raised positioning pins are arranged at the inner wall of the horn-shaped opening of the bottle cover, and vertical positioning grooves are arranged at the shoulder of the bottle body. The oral liquid packaging bottle is scientific and reasonable in structural design, adopts an innovative easy-opened design, is convenient to open for use, has an anti-theft function, is a disposable oral liquid bottle, has the outstanding advantages of strong environmental protection, and good safety and sanitation performance, and also has the advantages that the cost is low, the machining and the manufacturing are easy, the package and the conveyance are convenient, and the like.

A pressure balanced valve for an expander of a Rankine cycle heat recovery system includes a valve body that extends along a longitudinal axis. The valve body includes a valve head and an intermediate flange structure spaced apart from each other along the longitudinal axis. The valve body defines an internal flow channel having at least one output port and at least one inlet port. The at least one output port of the internal flow channel is defined by a cylinder chamber side of the valve head. The at least one inlet port of the internal flow channel is defined by a valve stem side of the intermediate flange structure. The internal flow channel is operable to communicate fluid pressure between the cylinder chamber side of the valve head and the valve stem side of the intermediate flange structure.

A method for operating a mineral material crusher, a system including a crusher, and a crushing plant. The mineral material crusher, includes a first crushing element and a second crushing element, defining a crusher gap therebetween. The crusher gap is maintained using at least one hydraulic cylinder, the hydraulic liquid pressure in at least one of the hydraulic cylinders is measured and hydraulic liquid is evacuated from the hydraulic cylinder when the hydraulic liquid pressure exceeds a set opening pressure limit. During the crushing process the following steps are repeated: generating, based on the hydraulic liquid pressure measurement, a representative value of a normal hydraulic liquid pressure in the at least one hydraulic cylinder caused by the crushable material in that crushing application; comparing the generated representative value and the set opening pressure limit; and selecting opening pressure limit which is higher than the measured normal hydraulic liquid pressure.

The invention relates to an opening and closing mechanism, specifically a cushioning opening and closing mechanism, which belongs to the technical field of toolboxes. It includes a sealed box and an opening and closing plate. The inner side of the sealing box is connected to the opening and closing plate through a telescopic strut assembly. There are strut avoidance grooves on both sides of the opening and closing plate; one end of the sealing box and the opening and closing plate is connected into one body through a damping hinge; The body is provided with a lock, and the lock can lock the sealed box body and the opening and closing plate.
