Abstract: A gas burner for burning a gas with a low calorific value. The gas burner may be for burning a synthesis gas issuing from the gasification of biomass.

Abstract: A leno device uses the link mechanisms (31, 31?) to derive the movement of its half shaft (28) from the movement of its pull or lifting shafts (2, 3). The link mechanisms (31, 31?) connect the shaft rods (4, 5) of the pull or lifting shafts (2, 3) to the half shaft (28), whereby a connecting rod (32, 32?) extends between the two pull or lifting shafts (2, 3) from the top to the bottom through said shafts. The upper end of the connecting rod (32, 32?) is connected, on both sides of the connecting rod (32 32?) via connecting levers (33, 34, 33? 34?), to the joints (36, 37, 36?, 37?) that are connected to the upper shaft rods (4, 5) of the pull or lifting shafts (2, 3).

Abstract: A governor for controlling a hydraulic transmission including a housing, a flyweight assembly rotatable within the housing, an axially movable hydraulic transmission control valve within the housing connected to the flyweight assembly for axial movement in one direction within the housing in response to rotation of the flyweight assembly within the housing, a spring axially biasing the valve for axial movement in the opposite direction within the housing, means for sensing an underspeed condition of the transmission and including hydraulic elements responsive to the underspeed condition in excess of a predetermined condition for axially shifting the valve.
