Title: Regeneration of contaminated solvents from dry cleaning of textiles
Inventor: BAUMANN WALTER DR ING
IPC: B01D3/06
Filed: 1995-03-01
Abstract: In a process for regenerating a contaminated solvent,contaminants whose boiling points lie above that of the solvent are sepd. in an evaporative first stage (26), whilst contaminants whose boiling points are below that of the solvent are sepd. in a condenser (40) in which the solvent is condensed (41) and the more volatile contaminants, which may include water, leave as a vapour (61). The improvement is that the temperature of the vapour of the contaminants and of the condensed solvent at their respective outlets from the condenser are controlled independently of one another using a separate cooling circuit whose coolant passes through the condenser. Also claimed is an appts. for the process comprising an evaporator (26) and a condenser (40) through which a coolant flows from a separate cooling circuit, by means of which the temps. of the liq. and vapour streams leaving the condenser can be independently controlled.

Title: Solar energy storage to power buildings
Inventor: SCHAEFER ERNST DR MED
IPC: H02J7/35
Filed: 1995-05-29
Abstract: In the recovery of the energy requirements of buildings, sodium hydroxide is broken down using solar energy into sodium and water, with oxygen release. When energy is required, oxygen is produced by the bringing together of sodium and water, together with a release of heat. The oxygen is subsequently combusted giving out further heat energy, and additionally produces electricity in combustion engines through a generator.

IPC: H02P8/14
Filed: 1995-06-16
Abstract: A method and a device are proposed for actuating a step motor. The step width and direction of rotation of the step motor (9) are determined in a control device (13) and forwarded to a control system (20) for actuating the step motor (9). At each step timing signal from the control device, a step is executed. The step width given by the control unit (13) is subdivided by the control system (20) into a number of smaller sub-steps whose individual step widths are less than that given by the control device. Those sub-steps are forwarded to the step motor (9) in a number of time-offset pulses from the actuating circuit.

Filed: 1995-11-04
Abstract: The clutch has a device for compensating for wear on the friction linings (7) by moving the pressure plate (3) axially toward the counter-pressure plate (6) through distances commensurate with the wear. To compensate for wear, an annular adjusting member (17) is (a) movable relative to either the housing (2) or the pressure plate, is (b) supportable by either the housing or the pressure plate, is (c) at least indirectly biased by a clutch spring (4) against either the housing or the pressure plate and has (d) its adjustment movement blocked as a function of at least one parameter which develops in use of the clutch. The blocking action may be against displacement in at least one of two directions. The directions include a displacement in the direction of the axis and a displacement in a circumferential direction of the pressure plate relative to that of the housing and the pressure plate. Embodiments are described in which the chosen parameters are rotary speed and temperature. The former employs a variety of centrifugal devices and the latter a bi-metallic strip.
