Title: Rapid deicing system for canals and ports - blows compression warmed air into water through perforated pipes
Inventor: HUBRICH CHRISTOPH DIPL ING
IPC: E02B15/02
Filed: 1974-07-12
Abstract: The system for rapid deicing of ship canals and ports used pneumatic heating which transfers large quantities of heat rapidly into water. The heating source is preferably a Roots blower. The air which is warmed on compression by the polytropic process at constant volume is blown into the pipeline under water and it is allowed to escape into the water. The warmed air is blown through noncorroding plastics pipes, which can be used in salt water. The heat transfer is efficient owing to turbulent outlet from pipe perforations which ensure fine distribution of bubbles. These perforations are arranged on the underside of pipes to minimise blocking up effects when not in use. The blowers (2) on the short (1) pump air into pipe (6) in water and the pipes can be positioned to improve water circulation.

Title: Furniture with support columns and stabilising transverse feet - has lightweight easily fixed decorative flaps and concealing sturdy feet
Inventor: QUAPP HANS
IPC: A47B91/06
Filed: 1974-08-19
Abstract: The table or furniture unit comprises a U-shaped support frame wherein the web forms the upright support column T mounted on horizontal stands or feet (5) in the form of cross-beams (5, 6) made of a metal section and covered by decorative flaps (7, 8). The inner walls of these flaps (7, 8) run at a distance to the sides of the cross-beams on account of the inner dimensions of the flaps which are larger than the cross-section of the beams so that the flaps can be secured in their position relative to the support beams (5, 6) by means of inwardly projecting distance webs (9). These decorative flaps can be provided with a central opening so that they move up and down on the telescopic column. They an also be made of plastics, for example in the injection moulding process in various colours.

Title: Particle size distribution measurement apparatus - uses reference and measuring light beams and has particle filters in measuring beam
Inventor: HOLLAENDER WERNER
IPC: G01N15/02
Filed: 1975-10-04
Abstract: The apparatus for measuring the size distribution and number of small particles consists of a filament lamp light source and condenser lens. The light produced by the lens is parallel and of even intensity over the cross-section. It is focussed onto a transparent airtight measuring chamber divided by a filter membrane. Aerosol particles pass into the chamber and the light transmission of the filter is subsequently altered. A differencing arrangement uses part of the light source output as a reference signal. This is reduced in intensity by polarised filters or similar means. The reference beam and the measuring beam passing through the filter are passed through an opto-electronic processor which determines the number of separated aerosol particles.

Title: Staple fibre twisting process - uses successive counter swirling air streams to give core with outer strands twisted round in opposite direction
Inventor: GOETZFRIED KONRAD
IPC: D01H1/115
Filed: 1975-11-20
Abstract: The fibres are twisted in an air stream in opposing spirals. When the sliver has been drawn out and broken into individual untwisted strands, they follow the converging path of a triangle into the entry of the twisting tube. The counter currents of the airstreams develop a twisted yarn core, the outer strands being continuously twisted round it in an opposite direction. Process gives a high-speed mfg. operation delivering a yarn of high tensile strength.

Phenolic OH vicinal to phosphite ester bond increases anti-oxidative and light-stabilising activity of (I). (I) are solid and can be admixed to plastics together with the other solid stabilisers. In an example, methyl-(4,6-di-tert. butyl)pyrogallol phosphite was prepd. from 0.7 mol 4,6-di-tert.-butyl pyrogallol and 1.5 mol. trimethyl phosphite.
