Patent FR-2475599-A1 (FR)
Inventor: COELUS GASPAR
IPC: E02D11/00
Filed: 1980-02-13
Abstract: 1. A process for driving into the ground or removing from the ground elements such as piles (1), tubes or sheeting piles (60) in which - a given amount of kinetic energy is formed by moving a ram (14, 70) which is directed in the diretion of movement of the head of the element (1, 60), - the ram (14, 70) is gradually slowed down by resilient means (19, 68) integral with the head of the element (1, 60) which accumulate the kinetic energy in potential form, the resulting force of the deceleration being communicated to the head of the element (1, 60), - the potential energy accumulated by the resilient means (19, 68) and which has not been absorbed by the movement of the element (1, 60) is retransferred to the ram (14, 70) in the form of kinetic energy, characterized in that : - this energy is increased by the action of hydraulic cylinders (21, 22 and 71) and this energy is transformed into potential energy corresponding to a greater height of the ram (14, 70) above the head of the element (1, 60), - the ram (14, 70) is driven back towards the head of the element (1, 60) while transforming the potential height energy into kinetic energy.

Title: Bentonite slurry as grout substitute - contg. quicklime for ground consolidation, preventing collapse or caving in of walls
IPC: C09K17/10
Filed: 1980-07-01
Abstract: Substitution of a grout based on bentonite and cement, a cement milk, a mortar or a concrete for a bentonitic slurry contd. in a cavity is described. The improvement comprises utilising a bentonitic slurry contg. a quantity of lime which corresponds to or slightly exceeds the amt. of lime needed to confer the max. rigidity tothe slurry.

Abstract: In the housing (1) of the float valve there is axially displaceably arranged a valve body which interacts with an inlet nozzle which is fitted in the inlet nipple (3). The valve body is controlled by a float (6) via a lever linkage (8). The float is arranged in a float housing (5) which has, at the bottom, a discharge opening (5a) controlled by a control float (9). The water flows through a discharge pipe (4) into the flushing cistern, the discharge pipe passing through the centre of the float (6) and the float housing (5). The float (6) is screw-connected to a float pipe (7) which can move axially on the discharge pipe (4) and bears, at the top, an annular groove (7b) into which the lever linkage (8) engages. The float valve has an extremely compact and therefore space-saving construction.
