Title: Process for the production of a textured yarn
Inventor: BAUER KARL DR ING
IPC: D02G1/16
Filed: 1981-08-24
Abstract: A multiple-thread synthetic continuous yarn undergoes a blowing treatment, in such a way that individual filaments project in regions from the yarn body as snarls, loops, arcs or the like. Downstream of the blowing nozzle, the yarn thus treated undergoes a singeing treatment, with the result that the snarls, loops, arcs or the like are opened and a length of the projecting individual fibres which is to be predetermined is maintained. The singeing treatment can take place before or after a thermosetting operation. The yarn can be revived, before the singeing, by means of a special preparation. The yarn can be singed in the false-twisted state. The singeing treatment can take place in a stabilising zone, in which the yarn undergoes elongation, as a result of which metastable loops are eliminated. In the machine for carrying out the process, the singeing device is located downstream of the delivery unit following the blowing nozzle.   <IMAGE>

Title: Compressed air generating unit for air bubble bathing systems with digital operating display and microprocessor-controlled operating program
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1982-03-17
Abstract: In the compressed air generating unit for an air bubble bath all operational elements and all display elements are combined in a clearly divided operation and display field which is hermetically sealed against penetration of water from the outside, meaning greater safety for equipment and user. The digitally displayed values (e.g. temperature of bath water or atmospheric humidity) which are measured by appropriate sensors on the hose nozzle on the bath water side or on the compressed air generating unit itself are processed with the aid of in-built microprocessors and transformed into commands for the air bubble heating, motor speed regulator, etc. (e.g. thermostat function for bath water). Another task of the microprocessors is the control of the air bubble bath program, e.g. interval operation with "recovery phases" which are programmed either by the bather or at the factory and can be conveniently called up on the keyboard.
Patent DE-3210236-A1 (DE)
Title: Process for the purification of a waste gas stream contaminated with vaporous and/or gaseous pollutants
Inventor: NITSCHE MANFRED DR
IPC: B01D53/02
Filed: 1982-03-20
Abstract: In a prepurification stage, the unpurified waste gas stream is cooled and prepurified in a mass transfer and heat exchange column (2) by a cooled circulating liquid entering in countercurrent at the head of the column (2) via a distribution device (4), some of the pollutants being washed or condensed from the waste gas stream and collected in the column bottom. The waste gas stream prepurified and cooled in this manner is conducted to a final purification stage via an absorber unit, in which the pollutants are adsorbed except for a small residue. The waste gas stream purified in this manner is discharged, while the pollutants deposited on the adsorber packing are expelled during the regeneration of the adsorber packing and are returned into the heat exchange and mass transfer column, where they are subjected to the prepurification together with further unpurified waste gas stream introduced into the column (2). <IMAGE>
Patent DE-3214103-A1 (DE)
Title: Toboggan
Inventor: LUECKE HANNS W
IPC: B62B13/12
Filed: 1982-04-16
Abstract: Toboggan with broad, long, ski-like runners, which permits reliable use even on so-called ski slopes by means of a series of constructional features. These features are both the long runners which cover a large area and can be tilted in a controllable manner in the travel direction to the left and to the right, as a result of which oblique descents down inclines are also possible. At the same time, displacement of the centre of gravity with respect to the slope is additionally achieved, which promotes stability on the slope. In this respect, this structure behaves like a skier who travels with his skis tilted in transversely with respect to the slope. The excellent cushioning of the driver against jolts from the surface he is travelling over is achieved by means of the tubular frame which is open at the rear and on whose upper side the seat is mounted. (Effect approximately as in a steel tubular chair which has the same tubular frame construction.) Additional inherent suspension is achieved by means of freely protruding runner tips and ends. There are braking devices on the two runners which can be actuated both individually and together for overall braking by means of foot pressure. A change in the travel direction takes place by means of braking of the runner on one side with simultaneous angling off of the two runners with respect to the side of the braked runner.

Title: Expanding dowel with setting-force indication
Inventor: LIEBIG HEINRICH
IPC: F16B13/00
Filed: 1982-07-13
Abstract: The dowel (14) exhibits a slit expanding sleeve (20) which can be expanded by at least one expanding body engaging in the inner end of the bore, preferably two expanding bodies (26; 28) engaging in the inner end and outer end of the bore. A threaded bolt (30) engages in the expanding body (26) at the inner end of the bore, which threaded bolt is led freely displaceably through the expanding sleeve (20), the optionally provided expanding body (28) at the outer end of the bore, and a spacer sleeve (32) adjoining at the bore-opening end. The threaded bolt then terminates in a bolt head (34) or bears a screwed-on nut, and beneath said bolt head or nut there is arranged a shim (30) which lies on the upper side of a workpiece (10) to be fastened and through which the spacer sleeve passes in a displaceable manner. A tube section (36; 50) is arranged between the spacer sleeve (32) and the expanding sleeve (20) or the expanding body (28) at the outer end of the bore. The dimensions and material properties of this tube section are selected such that it is crushed by axial compressive forces when the dowel is tightened and, when the predetermined setting force has been reached, said compressive forces are of such a magnitude that the yield point of said tube section is reached. Between the bolt head (34), or the nut, and the shim (38), a follow-on element is provided which can be deformed in the axial direction and compensates for the follow-on of the spacer sleeve (32) occurring when the setting force has been reached due to the yielding of the material of the pipe section (36; 50). <IMAGE>
