Title: Regeneratable adsorber for solvent vapour - comprises condenser and inflatable buffer store, for use with dry cleaning systems
Inventor: SIEBER HELMUT
IPC: B01D53/04
Filed: 1990-07-26
Abstract: Hot air or steam regeneratable vapour adsorber, comprising a condenser and an inflatable buffer store for the temporary holding of air-vapour mixt. during regeneration phase. More specifically, a chamber for solvent treatment of goods is connected to an adsorber contg. adsorbent material, e.g.  activated carbon, molecular sieve material, etc. Vapour from chamber is transferred by pump in the direction of arrow via condenser, into the adsorber. Purified air is discharged along lone, in direction of arrow, back to the adsorber in a closed circuit with valves open. After closing valves, regeneration is by hot air, produced in the heater and supplied via pump through lines. Displaced vapour, and air, enter the condenser which is temporarily overloaded and slightly pressurised. With valve open, the excess air vapour mixt. enters and inflates the bladder. As the vapour is condensed and the residual air cools, the bladder deflates, and valve can be closed in readiness for further adsorption. USE/ADVANTAGE - Compact solvent recovery system for solvent-cleaning machines e.g. for textiles, metal objects, electronic components.  A single adsorber unit system which avoids discharge of desorbed vapour to the outside environment.

Patent DE-4035977-A1 (DE)
Inventor: RICHTER BRUNO DIPL ING
IPC: G01B11/24
Filed: 1990-11-12
Abstract: The proposal is for an opto-electrical measuring process for determining cross-sectional dimensions especially of web-like objects with reference to at least one straight line at the cross-sectional periphery and touching it at at least two points, and devices for implementing this process. A light beam which is moved inside a measuring area in a parallel shift exceeds limits of a shadow of the object in the measuring area at measurable places in the measuring area. The same light beam after being deviated or another light beam is used to provide point illumination of the surface of the object at a predetermined angle and the distance of the light beam axis at the position of a given shadow border to this illuminated point is found by its display at an angle differing from the illumination angle and the evaluation of the position of the image by triangulation calculation laws. By shifting the entire measuring system in relation to the orientation of the cross-section of the object and about an axis parallel to its longitudinal axis, the curve of the distance found undergoes a detectable unsteadiness which is characteristic of that shifted position of the measuring system at which the axis of the light beam at the position of the given shadow boundary touches the cross-sectional periphery at at least two separate points.

A preloading coil spring (38) connects the locking ring to the driven bush and together with friction brings the blades rapidly to rest. USE/ADVANTAGE - Fast action clutch for portable power tool. Positive drive without dependence on friction. Simple design.
