A conveyor grate for the transport and cooling of bulk material, for example cement clinker, comprises a grate floor having multiple planks (12), adjacently situated transverse to the direction of transport on associated support structures and operationally moved longitudinally relative to one another individually or in groups, with moving gaps (14) designed as blow openings situated therebetween, and a method for operating such a conveyor grate. The mutually facing side edges or side edge regions of two adjacent planks (12) form two complementary, mutually engaging profiles between which the moving gap (14) is formed. In the method according to the invention, at least a quantity of the cooling air is blown through the moving gaps (14) which is sufficient to blow the moving gaps (14) completely open.

Two embodiments of a guard are provided for protecting a padlock securing stanchion levers in their door locking position. An opening in the front wall of the guard permits its use with padlocks having long shackles as well as those with regular length shackles while retaining the compactness not normally retained for the extended length of the shackles. The preferred construction lock guard has a pitched roof and a pair of legs on its laterally outer sides extending downwardly behind the stanchion lever at laterally opposite sides of the stanchion latching mechanism that increase stability, rigidity of the housing and protection of the latches.

An integrally bladed rotor disk (20) for a turbine, including rotor blades (40), which are joined in a substance-to-substance bond to a disk element (30), and a sealing device (60) for preventing or reducing the extent to which cooling air is able to flow from a high-pressure side (12) of the rotor disk (20) through openings (24) on the rotor disk (20) to a low-pressure side (14) of the rotor disk (20).

The invention relates to an elevator car door lock device and an elevator. The elevator car door lock device comprises a belt, a door vane base, a first oscillating bar, a second oscillating bar, a horizontal crossbar, a telescopic device and a car door lock hook. The belt is connected with the first oscillating bar, and the first oscillating bar and the second oscillating bar are connected to the door knife base in a rotating mode. One end of the horizontal crossbar is connected with the car door lock hook, and the other end of the horizontal crossbar is provided with a protruding block. The protruding block abuts against one side, far from the first oscillating bar, of the second oscillating bar. The telescopic device comprises an energized magnet, a connection rod, a limit plate, a push plate and a telescopic spring, wherein the telescopic spring is arranged on the connection rod in a sleeving mode. The second oscillating bar is provided with a through hole matched with the connection rod, one end of the connection rod is connected with the limit plate, and the other end of the connection rod penetrates through the through hole and is connected with the push plate. The two ends of the telescopic spring abut against the push plate and the face, opposite to first oscillating bar, of the second oscillating bar respectively. According to the elevator car door lock device, the stroke difference between a landing door and a car door is greatly reduced, synchronicity between the landing door and the car door is improved, the length of an upper sill of the car door is greatly reduced, and an elevator well can be designed to be narrower.

Probe pins related to the present invention are formed from a material which consists essentially of one or more elements selected from the group consisting of platinum, iridium, ruthenium, osmium, palladium and rhodium. A material obtained by adding one or more elements selected from the group consisting of tungsten, nickel and cobalt to this metal may also be used.

Cam belt, particularly for agricultural machinery, produced from a polymer provided with reinforcement inserts, has cams on the inner side of the cam belt that are used to drive cam belt. A first flank faces in the running direction of cam belt and a second flank faces in opposite direction. Cams are spaced apart from one another by gaps in a predefined division, and gaps are delimited by first flank and second flank of two adjoining cams and a base which connects two flanks. During operation of cam belt carrier of a cam wheel resting against second flank of one of adjoining cams and against the base of a gap engage with the gaps. On outer side of belt, functional elements are fixed by a fastener which from inner side of the belt passes through the cam belt and the functional elements via at least one through hole.

A radome for housing a radar system comprises a plurality of interconnected curved radome thermoplastic composite material panels, each curved radome thermoplastic composite material panel having a plurality of interconnecting edges, a foam core, an inner skin, an outer skin, and a plurality of three-dimensional fiber bundles tying the inner skin and the outer skin to each other through the foam core, inhibiting delamination. The radome includes a hydrophobic exterior surface that is self-cleaning and requires zero maintenance for 25 years.
