Title: Sistema de monitorizacion de tensiones en anclajes de obra.
Inventor: DIMAS SUAREZ JUAN MANUEL
IPC: G01L1/24
Filed: 2008-08-26
Granted: 2011-02-09
Abstract: Sistema de monitorización de tensiones en
anclajes de obra. 
     El sistema permite la monitorización de
tensiones de manera que sus mediciones no se vean falseadas por el
efecto de corrientes eléctricas parásitas. Para ello, a partir de la
estructuración de un anclaje convencional, constituidos mediante una
cabeza (2) y una armadura (3) rematada en un bulbo o zona de anclaje
(4), la invención centra sus características en el hecho de que el
citado anclaje incorpora una serie de sensores de fibra óptica (5),
los cuales se montan en serie en un solo cable de fibra óptica, de
forma solidaria a una barra de acero corrugado (4), de manera que
con el citado cable de fibra colabora un interrogador (6) que envía
una señal óptica y recibe una longitud de onda reflejada por cada
sensor de fibra óptica (5), interrogador (6) susceptible de ser
conectado a un ordenador (7) para análisis de los datos
obtenidos.

Title: Device for emptying refuse containers
Inventor: DELLE KLAUS
IPC: B65F3/08
Filed: 2000-06-02
Abstract: The invention relates to a device for emptying refuse containers into a collecting bin (3), comprising a lifting device (5) with a carriage unit (6) and at least one swivel device (20) mounted on the lifting device, on which a receiving device (10) grasps the refuse container. A four-bar guide (30a,b) arranged on the swivel arm (40a,b) and provided with an upper guide rod (31a,b) and a lower guide rod (32a,b) supports the lifting frame (11) with the receiving device (10). The upper guide rod (31a,b) extends beyond its pivot point (34a,b) as far as the collecting bin (3) and forms an actuating lever (33a,b), whereby a cylinder piston device (21) pivots between the free ends thereof and the carriage unit (6). When the cylinder piston device (21) is actuated, its pivot point (25) on the four-bar guide (30a,b) moves along the arc of a circle (25) between both pivot points (34a,b,37a,b) on the four-bar guide (30) on the swivel arm. This improves the limited ground clearance of vertically conveying lifters and increases height capacity for receiving containers onto the inventive device. The cylindrical piston device is substantially protected against damage.
