Patent DE-4203293-A1 (DE)
Title: Recirculating swimming pool water treatment - uses trickle gassing in an ozone reactor connected to an ozone generator
Inventor: DEPPING WILHELM
IPC: C02F1/78
Filed: 1992-01-31
Abstract: To treat recirculating water with ozone, at swimming pools, the water passes in a counter flow through an ozone reactor connected to an ozone generator for trickle gassing, before passing under system pressure through a pressure filter. Air is fed under pressure into the upper part of the ozone reactor (1), filled with the untreated water. The water level is depressed to a given level, and a mixt. of air and ozone is fed under system pressure into the lower part of the ozone generator (10) by an underpressure to give suction. The upper section of the ozone reactor (1) has a connection to an air compressor, with a connection system at the lower section, above the water level, to a water ring compressor (9) between the reactor (1) and the ozone generator (10). The air compressor is activated until the water level in the reactor has been depressed to a given level (19). The water ring compressor (9), which sucks ozone from the ozone generator (10) by an underpressure, then delivers an ozone/air mixt. under system pressure into the ozone reactor (1) above the water level (19). USE/ADVANTAGE - The method is for treating recirculating water in swimming pools, which uses a simple system at lower pressures than conventional assemblies, to give lower installation costs.

Patent DE-4244207-A1 (DE)
Inventor: SACHER DOMINIC
IPC: F16B7/04
Filed: 1992-12-24
Abstract: For the rapid and simple releasable connection of two tubes (pipes), preferably of a load-bearing system, the invention proposes a tube clip which has a basic element (2, 8), for example in the form of a section of a circle cross-section, and two pins (3) attached on the inner wall of the basic element. The pins (3) each engage through two mutually aligned through-passage bores in the end regions of the tubes which are to be connected, and the basic element snaps onto the tubes, widening in an elastic manner in doing so. The tube clip can be fastened rapidly without the aid of a tool, sits securely on the tubes, in the tension region of the load-bearing member in the case of a load-bearing system, and can be rapidly and simply removed again without the tube surface being scratched, for which reason the tube clip is also extremely well suited for powder-coated tubes. <IMAGE>

IPC: D06F75/38
Filed: 1993-05-14
Abstract: In an iron with a soleplate, on which a heating subassembly is fastened so as to bear sealingly thereon over a large middle surface region, the soleplate having an upper layer of a metal of good thermal conductivity and a lower layer of a wear-resistant material, it is proposed that the lower layer of the soleplate consist of fine steel and be combined unreleasably with the metal layer of good thermal conductivity to form a composite material, and the heating subassembly be fastened in its edge regions to the soleplate. The bimetallic effect of the soleplate taking effect during heating ensures a particularly good large-area bearing of the soleplate on the heating subassembly.

Title: Mechanical two-circuit braking system
Inventor: WIELAND DIETER DIPL ING
IPC: B27B17/08
Filed: 1993-09-11
Abstract: Braking systems known hitherto for hand-held tools, in particular for portable electric chain saws, comprise a mechanical safety brake which is susceptible to wear and an electrical coasting brake which has complicated circuitry. The novel braking device provides, as coasting brake, a coasting brake which works purely mechanically, is constructionally simple to realise and inexpensive (cost-effective) and has a high functional reliability. The coasting brake is a brake which acts mechanically on a rotational part and is capable of being actuated by releasing a switch lever for starting the drive motor. The mechanical two-circuit braking system is particularly well suited to installation in electrically operated hand-held tools, in particular chain saws.
