Title: Screen panel center retainer system
Inventor: LANE TRACY LEONARD
IPC: B07B1/46
Filed: 2012-03-13
Granted: 2016-09-06
Abstract: A screen panel center retainer system for a vibrating separatory machine utilizes a center retainer that is provided with a retainer base which is adapted to be secured to screen stringer rails of a vibrating separatory machine. A pair of retainer channel legs form an upper portion of the center retainer and have screen panel edge receiving slots. A locking strip, having a wedging tongue, is used in conjunction with the center retainer. The wedging tongue is insertable into the channel on the center retainer which is defined by the two retainer channel legs. Flow control dams and cross dam retainers are used in conjunction with, and in addition to the center retainers and locking strips. The cross dam retainers are provided with locking strip end receiving pockets to compensate for changes in the length of the locking strips. The screen panel center retainer system is configured to provide a functional, universal installation of screen panels on vibrating separating machines.

Abstract: The invention relates to a tower for a wind energy plant having walls which are produced at least partially from individual wall sections made from a wooden material, the wall sections being connected to one another via connecting means, and to a method for erecting a tower of this type. It is therefore an object of the invention to provide a tower for a wind power plant, which tower makes a greater rotor blade length possible with an unchanged height of the tower of the wind power plant and with an unchanged projection of the rotor beyond the tower outer side as viewed from the tower center axis. The object according to the invention is achieved by virtue of the fact that an falsework is provided at least partially in the tower interior, by way of which falsework the wall sections are connected in a retentive manner, and the wall sections are arranged on the falsework in such a way that a surface line which is produced in the case of a vertical section through the tower wall which is formed from wall sections has a gradient which becomes greater as the tower height increases.

Abstract: A hydraulic fluid coupling for attaching two hydraulic hoses that comprises an inline swivel joint to prevent twisting of the hoses. The coupling comprises a first and second coupling portion, with the second coupling portion rotatable relative to the first coupling portion. There are two bearings and a ring shaped piston that slides toward the second bearing in response to fluid pressure inside the coupling. Engagement of the piston with the second bearing urges the second coupling portion towards the first coupling portion, against the action of fluid pressure between the first and second couplings. This reduces the load on the first bearing and transfers some of that load to the second bearing, thereby making it easier to rotate the second coupling portion.
