Title: Non-return valve, especially a nozzle non-return valve
Inventor: WOLTERS HANS RICHARD
IPC: F16K15/06
Filed: 1981-10-27
Abstract: The invention relates to a non-return valve, especially a nozzle non-return valve, for installation in gas or liquid pipelines, consisting of a housing which has mechanically machined holders on its inside for the internal fittings which consist of a valve plate or ring and, if applicable, nozzle bodies. Because of the housing, which consists of cast metal, the non-return valves, especially of large sizes, are very heavy and expensive.

Title: Device for the introduction of gas or air into liquids and/or for circulation or generation of flows in liquids
Inventor: LIND HELGA
IPC: B01F7/00
Filed: 1981-11-12
Abstract: In a device for the introduction of gas or air and/or for the generation of flows in liquids or liquids with solids, for example in activation tanks for the biological treatment of effluents, the flows are generated by at least one propeller mounted on the free end of a shaft dipping into the liquid, and the gas is introduced under pressure through one or more gas feed line(s) ending in the region of the propeller(s), where the gas or the air is broken up by the propeller into extremely fine bubbles, taken along by the flow and finely distributed in the liquid by turbulence. In this way, it was possible considerably to increase the introduction of gas or air as compared with the known devices in which the gas or air is drawn in by the vacuum produced during the generation of the flow. Since, moreover, the generation of a flow and the introduction of gas are mutually independent, the device can be used selectively and alternately both for nitrification (flow generation with simultaneous oxygen introduction) and for denitrification (flow generation without oxygen introduction) in treatment plants. <IMAGE>

Title: k<2>-quadrature amplitude-modulation system with reduced bandwidth requirement
Inventor: BESSAI HORST
IPC: H04L27/34
Filed: 1983-02-01
Abstract: With the invention, the bandwidth requirement of k<2>-quadrature amplitude-modulation (QAM) systems (k = number of amplitude stages, k<2> = number of signal states) is intended to be reduced. A transmitting-end digital transverse filter structure with a low-pass character is used for this purpose, in which the binary input signal undergoes a binary k-stage coding prior to the conventional QAM coding. From statistically evenly distributed binary signals, the digital transverse filter structure generates k-stage signals with only single-stage transitions between consecutive symbols. It thus causes the relevant signal components to shift towards lower frequencies. At the receiving end, the k-stage coding is reversed in each case by means of k-1 threshold value discriminators, digital differentiators and flip-flops. In the case where k = 3, i.e. in a 9-QAM, no flip-flops are required in the decoder (Fig.1). <IMAGE>

Title: Jacket concrete composite wall hollow on the room side
Inventor: WEBER HILAR
IPC: E04B2/86
Filed: 1983-02-15
Abstract: The innovation relates to a jacket concrete composite wall hollow on the room side, in which, unlike the specific jacket concrete walls, there is arranged only on the outside of the outer walls a damping- material jacket, preferably made of rigid foam or laminated lightweight panels. On the room side, i.e. on the inside of the outer walls and on both sides of the supporting inner walls, there is arranged in the innovative wall a hard a one-way thin form which is reinforced against the concrete pressure by means of lath pieces arranged at intervals and applied in a rib-like manner. After application of the room-side wall covering, room-side hollow layers are created, which bring about a functional improvement in relation to the typical jacket concrete wall. The supplementary shell effect of a room-side hollow layer improves the airborne noise protection, brings about additional heat protection and makes possible efficient insertion of installation lines of all types, in other words also those which can serve for wall heating and wall cooling. The connection of the different composite wall/jacket shells to form a concrete-receiving form (Fig. 1) takes place in this case by means of clamping elements (Fig. 3) of the locking laths (5), which are connected by means of nailed in (8) band-iron pieces (7), and these locking-lath pieces (5) engage behind the lath ribs (1) of the thin form (2) in the jogs (4) of the rib laths (1), while, in the outer walls, the outer locking lath (5) ...
