Abstract: First and second endless conveyor arrangements respectively comprise a first and a second endless conveyor having a first and a second run. The second run adjoins the first run, and they together define an elongated path for fibrous material which is to be transported gripped between the runs. The first elongated endless conveyor comprises a plurality of parallel endless first elongated conveyor sections arranged side-by-side to define a plurality of elongated parallel first intermediate spaces extending along substantially the entire length of the first run. The second conveyor is similarly constructed so as to define similar second intermediate spaces. Along substantially the entire lengths of the first and second runs, the aforementioned sections of the conveyors project in direction from the respective run towards the other run into respective ones of the intermediate spaces of the other conveyor.

Abstract: One or more pantographs are connected below a working base and are connected with a main cylinder horizontal or inclined in respect to a supporting base so as to be driven to be extended or contracted. One or more comparatively short auxiliary telescopic cylinders are erected below the working base. During the initial phase of upward movement of the working base the auxiliary cylinders will act directly to push up the working base and, when it has been elevated to a predetermined height, the pushing force is shifted to the main cylinder so that the working base may be further elevated through the pantographs.When the working base is lowered, the pantographs and main cylinder will be compactly folded.

Abstract: During the manufacture of bricks, either before or after such bricks are introduced to the kiln for drying, selected brick from spaced positions in at least some of the rows are mechanically displaced to corresponding positions in upstream, downstream, or otherwise adjacent rows to effect an inter-row movement of some, but fewer than all of the bricks in any particular row. According to the invention, the selected bricks may be either pushed, lifted, lowered or combinations thereof from one row and transferred to a different row. One translating device designed for this technique is a snaggle-tooth pusher which engages and pushes some, but not all of the bricks in a row or rows. The selected bricks may be initially separated from the other bricks by means of either the snaggle-tooth puller, or by means of a vertically movable support plate which operates in conjunction with a slotted support plate immediately thereabove to remove and lower selected brick.

Abstract: An atomizing device for mixing or atomizing fluids without moving parts and comprising, in combination, a hollow tube which has a substantially cylindrical inner wall and a core member situated within the tube in substantial coaxial relationship with and spaced from the inner wall. The surface of the core member includes at least one non-intersecting helical channel which extends substantially continuously for the length of the channel. Also, channel-forming means is provided about the core member in close proximity with the surface thereof and with the inner wall of the tube, which comprises at least one layer of at least one non-intersecting helical winding. Each winding in any single layer is in the opposite direction to each winding in the next or adjacent layer and each winding in the layer nearest the core is in the opposite direction to the helical channel formed in the core member.

Abstract: The invention relates to connecting members for the ends of adjacent tubs of a scraper conveyor for the use in mines in which each tub comprises two side members.The supporting partition of each connecting member has a rear face serving as a support for one of the retaining flanges and extends transversely up to the corresponding side member or up to its extension. The supporting partition is located at the rear end of the projecting portion of the male member. The width of the lateral access opening for each partition is less than the maximum dimension of the cross-section of the corresponding locating slot of the partition. The junction zones between the lateral access opening and the locating slot at the partition constitute a lateral locking means for the connecting rods relative to the partition.

Abstract: A coupler for a trailer and the like, the coupler having a body and cap hinged together at a front portion and closeable along parting faces and having an internal cavity formed by the body and the cap for the ball which is conventionally secured to either the trailer or the towing vehicle. The body forms a major portion of the ball cavity and includes a ball centering upper surface which extends substantially laterally across the upper surface of the cavity, forming a self-centering bearing surface for the ball. An automatic closing device is formed on a front portion of the cap and body wherein insertion of the ball into the ball cavity automatically closes the cap with respect to the body. The closing device includes a protrusion on the cap at an opposite side of the hinge where the cap encloses the ball cavity. The protrusion extends through an aperture in the body and projects into the ball cavity when the cap is in an open position.

Abstract: A nozzle which produces a wide liquid jet includes a housing open on one side with two longitudinal edges, one of which forms one edge of the nozzle aperture with the other edge of the nozzle aperture formed by the free end of a wall connected to the other longitudinal edge of the housing. Bolts are distributed over the width of the nozzle aperture outside the nozzle aperture for adjusting the wall over the nozzle width to slightly deform the wall and change the thickness of the nozzle aperture.

Abstract: A counting and grouping apparatus for receiving articles such as fruit, marshalling the articles so as to fill up a number of parallel supply lines for presenting a number of the articles in line abreast in the leading positions in the supply lines, the number in the line abreast being equal to (or a fraction or multiple of) the number of articles to be counted into a group and a moving belt conveyor bearing at intervals along its length lines of fingers in line abreast across the belt, which fingers align with the leading position of the supply lines and shift the line of articles in said leading positions onto the conveyor belt as the fingers pass the exit ends of the supply lines. Gates are described for blocking one or more of the supply lines to control the number.The fingers have an upright operating position for picking off the articles and a non-operating position folded down on to the belt.

Abstract: A high velocity liquid jet cutting nozzle in which a nozzle member is supported in communicative connection with the outlet end of a high pressure liquid pipe by means of a mounting which is seated in a cup-shaped holder which is connected to the outlet end of the pipe.To provide a coherent, stable jet at liquid pressures of the order of 60,000 psi, the nozzle member is formed from a piece of artificial sapphire, such as a watch or instrument jewel, having a circular aperture diameter of between 0.05mm. and 0.40mm.
