Title: Tent with a dome-like configuration
Inventor: HANGLEITER ULRICH
IPC: E04H15/40
Filed: 1983-08-16
Abstract: The invention relates to a tent with a dome-like configuration, which has a mesh-like or grid-like framework, comprising bars, and a tent skin. The bars are made of a flexibly bendable polymeric material and are linear in the dismantled state of the tent, whereas, in the installed state, they are bent in correspondence with the dome configuration. Joint pieces are arranged at the points of intersection of the framework, to which joint pieces the bars, extending from joint piece to joint piece, are detachably connected. At points distributed over the circumference, in each case one framework part, having bars which extend at an acute angle towards one another, projects in such a way that the framework, in the dismantled state, forms a planar mesh or grid which bulges out to form a self-supporting dome configuration by exerting an inwardly directed stressing force on the projecting framework parts. The tent skin is detachably secured to the upper side of the framework.

Filed: 1983-09-20
Abstract: A process is disclosed for the purification of a gaseous stream contaminated at least with CO2 and H2S. The gaseous stream is preheated and subjected, in the presence of recycled SO2, to a catalytic conversion of H2S into elemental sulfur. The thus-obtained sulfur is separated, and the residual gas, which contains at least H2S, SO2, CO2, and water, is freed absorptively from SO2 after oxidative conversion of H2S to SO2. It is proposed that the residual gas, after oxidative conversion of H2S to SO2, is cooled in heat exchangers, preferably regenerators, and is subsequently scrubbed with a solvent consisting predominantly of tetraethylene glycol dimethyl ether.

Title: Metallic vacuum chamber having low eddy-current losses, for an accelerator having magnetic alternating fields, and a method for its production
Inventor: BANTHAU RUDI-HEINZ
IPC: H05H7/18
Filed: 1985-05-06
Abstract: The vacuum chamber according to the invention for a particle accelerator avoids numerous disadvantages (including a high space requirement and correspondingly poor utilisation of the magnetic field, a very high technological cost, including that for the metallisation and subsequent welding of the end zones of the ceramic segments, and the impossibility of matching the cross-section in an optimum manner to the beam aperture) initially by using metallic materials as the wall material. This is made possible by reducing the eddy-current losses in the chamber wall to a tolerable level, such as 60 watts per continuous chamber meter at an operating frequency of 12.5 Hz, by using a thin-walled (for example 0.1 to 0.3 mm wall thickness) elliptical tube (1) consisting of a metal having a high (at least 0.7  OMEGA  mm<2>/m) electrical resistivity, whose strength is increased by means of attached reinforcing ribs (2) of a material which is the same or similar. For production, the ribs are placed parallel onto the tube, whose circumference is somewhat smaller than that of the openings of the ribs, expediently with the assistance of a gauge (4), and the tube is thereafter upset, by drawing a mandrel (3) through it (which has a circumference which increases counter to the drawing direction) so far that the ribs are seated rigidly on it and can subsequently be firmly soldered or welded. Annular grooves (5) are cut into the elliptical mandrel, in which grooves (5), projecting [lacuna] somewhat beyond half the circumference ... Original abstract incomplete. <IMAGE>

Title: Two-keyboard electronic guitar, with an electronic neck
Inventor: PAVELEANU ION-AUGUSTIN
IPC: G10H1/34
Filed: 1985-05-28
Abstract: Two-keyboard electronic guitar with a built-in electronic neck and a special set of keys as the first keyboard and a set of keys built into the body of the guitar as the second keyboard. This instrument permits the majority of musicians who have some knowledge of the guitar to make use of further developments in keyboard microelectronics while playing. This effect arises because the guitarist must press down the strings to produce the desired notes, and at the same time the keys situated underneath are also pressed down, producing a contact inside the neck in accordance with each individual note of the fingerboard, the signal being further processed via the electronic line, as in a normal keyboard. The special electronic guitar neck, which comprises a plurality of removable parts in accordance with the spacing and the rods of the frets of the guitar fingerboard, is used for this purpose. The parts can therefore be replaced and repaired. The new instrument for a new musical era!
