Abstract: A system for dismantling installations present in a building (10) kept at a reduced pressure by virtue of a ventilation system. A hood (28) is brought above the installations to be dismantled. During the dismantling a fan (36) makes it possible to extract in the middle part of the hood (28) the air containing the aerosols due to the dismantling operations. After purification, a proportion of the gases is returned to the hood (28) and flows out at the periphery of the latter, thus creating a dynamic confinement region around the said installations. Another proportion of the gases is sent to the extraction pipework (18) in order to maintain the desired reduced pressure inside the building (10), the air entry (15) of the latter having been gradually shut off.

IPC: H02P25/024
Filed: 1989-01-13
Abstract: In the torque control method for multiphase electronically commutated electric motors, especially for synchronous motors (SM), a constant torque response is achieved by the required current values (I@, I@) for the phases to be regulated being formed independently from the torque regulation parameter (M
) and the rotor position. A dedicated current regulator (IR, IS) is allocated to each current phase to be regulated. The method allows a required current value (I@, I@) to be specified for each phase to be regulated, for any predeterminable torque response, as a function of the respective rotor position. A separate regulation of the required current values (I@, I@) ensures that the current which is commutating on relieves that which is commutating off precisely and hence no system-dependent torque interruptions occur. <IMAGE>

Abstract: The invention relates to a seal which comprises two lateral parts and an upper part. Each of these parts consists of inflatable beads made of an air-tight material which bear against the vehicle. The upper part runs to the left and the right in a vertical guide rail and each of the two lateral parts is suspended on rollers in a horizontal guide rail. The lateral parts and the upper part are preferably inclined towards the wall of the building at their bottom. The lateral parts can also bear against the wall of the building with their lower end. The movement mechanism for each of the parts consists of a cable- winding pulley with a drive device, a traction cable which runs over deflecting pulleys and is attached to the cable-winding pulley and to the outer end of the lateral parts or at the bottom part of the upper part, and a device for inflating and, if appropriate, deflating the sealing parts. Elastic traction elements which, in the case of the lateral parts, engage before the point at which the traction cable is distributed into three cables and are mounted at the bottom of the surround, and in the case of the upper part are mounted at the end of the traction cable and are fastened at the top of the surround so as to run over a deflecting pulley, ensure a constant tensioning for the traction cables and thus prevent the cables from unwinding. <IMAGE>

Abstract: In a pump apparatus in which the action of a piston (3) draws fluid into and pumps fluid from a valve chamber (1), a partition is provided between the piston cylinder (21) and the valve chamber (1). The partition is able to transmit the force of the piston action, and for this purpose the cylinder (21) side (A) of the partition contains a suitable liquid medium that transmits the actuation of the piston (3). A screening (19) means is provided in a passage between the partition (18) and the valve chamber (1) to screen out particles in the fluid that exceed a prescribed size. The overall effect is to eliminate wear to working parts of the valve caused by entrained particles. In addition there is a valve device (8,9) which prevents bounce or vibration of valve-­pieces during high pressure/high speed pumping operations.
