Patent DE-3513602-A1 (DE)
Inventor: GRABOWSKI GUNTHER
IPC: C02F3/08
Filed: 1985-04-16
Abstract: Simple and inexpensive hollow reactors in the form of spirals of corrugated plastic tubes, which are coiled in the same direction and clamped in large numbers adjacent to each other in a drum-like cage for use in biological waste water purification. This drum-like cage is mounted so that it can rotate in a waste-water-filled tank, in such a way that only the outer spiral turns project above the water level. During rotation in the opposite direction, each emerging tube end admits air, which on further rotation is trapped as a bubble in the spiral and is transported because of its inertia to the underwater spiral end. In this process the liquid contained in front of it in the tube is displaced and an equal volume is admitted at the inlet opening from the surrounding waste water. The air emerging from the inner spiral end rises upwards in individual bubbles between the spiral reactors. While part of the emerging waste water is entrained by the suction effect of the bubbles, the other part can flow away out of the laterally open inside space.

Title: Practising box for saxophones and clarinets
Inventor: WERTHER IRON
IPC: G10G7/00
Filed: 1985-07-18
Abstract: The practising box for saxophones and clarinets is a compact soundproof box, which reduces the volume of woodwind instruments to room level. There are three different sizes, for alto saxophone, tenor saxophone and for soprano saxophones and clarinets. The practising boxes are adapted to the instruments. The boxes have an aperture on the front side and the lid, through which aperture the instrument is introduced into the box. The mouthpiece projects through the opening in the lid. The openings on the front side are inserted in such a way that the musician can play the instrument without hindrance. The insides are soundproofed with structural foamed material. The outsides of the boxes are covered with artificial leather and are provided with handles and case corners. The practising boxes have the advantage that they reduce the volume of the instruments to room level over their whole registers, without altering alternation within the registers. The practising box is an alternative to inadequate conventional soundproofing devices and to expensive and bulky "practising chambers".
