Granted: 1992-07-07
Abstract: TENSIONER WITH INCREASED ARCUATE MOVEMENT               ABSTRACT OF THE DISCLOSURE         A belt tensioner comprising a pivoted structure carrying a pulley for rotation about a rotational axis and mounted on a fixed structure for pivotal movement between an increased range of angular movement.  The pulley is operatively positioned with respect to its rotational axis and the pivotal axis of the pivoted structure such that the lever arm to the pivotal axis through which the generally constant belt load force acts on the pivoted structure increases at a decreasing rate and then decreases at an increasing rate throughout the range of movement of the pulley between its first and second positions in a direction toward the second position.  The spring assembly is operatively associated with the pivoted structure so as to apply a spring torque to the pivoted structure which increases at a decreasing rate and then decreases at an increasing rate throughout the range of movement of the pulley between its first and second positions in a direction toward said second position.

Title: Cartridge to expel fluids under pressure
Inventor: REUTER INGOLF
IPC: F42B3/02
Filed: 1988-08-05
Granted: 1992-08-11
Abstract: Abstract The present invention discloses a cartridge (1) that is used to expel fluids at high pressure.  An essential element of the cartridge (1) is a driver (4) that is located axially between a propellant-charge chamber (2) and a fluid chamber (3).          On the flat end face (7) of the driver (4) there is an end piece (21) that is retained by a shape-locking or force-locking fit; this can be separated axially from the driver (4) by the pressure of the fluid flowing into the fluid chamber (3), and moved forwards towards the muzzle of the weapon.  Both the driver (4) and the end piece (21) lie closely against the inside wall of the bore (15) or the cartridge case (13).  When the propellant charge (27) is fired, the drive (4) expels a column of water, together with the end piece (21), into the shot holes of a gallery core in a gallery and thereby breaks up the rock of said core.

Title: Process and apparatus for processing slag from garbage incinerators
Inventor: SCHWYTER LEO
IPC: B03B9/04
Filed: 1989-06-15
Granted: 1995-08-08
Abstract: The slag that is formed in garbage and waste incinerators is cleaned of coarse material and iron directly after the slag outlet from the incinerator.  Separation into two fractions takes place after coarse cleaning, in a fractionating unit.  One of the fractions contains all the particles that are smaller than 2 mm.          At the same time, the dust is separated by a suction system.  Dust and particles smaller than 2 mm contain practically all the soluble harmful substances and have to be processed and stored observing special precautions.  The remaining, cleaned slag is dry, and can be used as construction material.  The process and the apparatus avoid the use of a water bath, so that no energy is needed for drying.
