Title: Multi-effect film evaporator - has evaporator surfaces, in effects where heat flux is critical, increased in area
IPC: C02F1/04
Filed: 1975-10-15
Granted: 1982-01-11
Abstract: Multi-effect film evaporator plant has evaporator surfaces, in those effects where the heat flux is critical in terms of scale formation or liq. film dry out, increased in area relative to the other effects. The risk of scale formation due to critical heat flux is greatest at the highest temp. effect evaporator surface and a reduction of overall temp. operating range may be avoided by having an enlarged evaporator surface area in that effect relative to the majority of the effects. The risk of dry out, i.e. complete diapperarance of liq. film, is greatest at the lowest temp. effect evaporator surface and the area of this surface is pref. enlarged relative to the majority of the effects. If the heat flux in any effect is too high instead of reducting the temp. range across the whole plant the surface area in that effect is enlarged. This reduces the temp. driving force within that effect and permits the evapn. temp. range to be restored to its full value. An overall saving in total area of evaporator surface can be achieved even through the surface area in one effect is increased.

Abstract: 1386732 Seaming non-metallic sheet material FIRESTONE TIRE & RUBBER CO 1 Feb 1973 [7 June 1972] 5200/73 Heading B5K The edges of two reinforcing cord-fabric plies having a coating of a compound of natural or synthetic rubber which is not vulcanized or cross-linked, the cords of each ply being parallel to each other and to said edges, are butt joined by bringing said edges together with the cords in each ply arranged parallel to the cords in the other ply and subjecting said abutting edges to sonic or ultrasonic vibrations to join the edges without causing cross-linking or vulcanization of the compound. The fabric, e.g. tyre cord fabric, may comprise parallel cords of rayon, nylon, polyester, steel or glass. In splicing apparatus, Fig. 1, a power source (not shown) supplies electrical energy to six converters 11 which change electrical energy into mechanical energy and which are connected to six boosters 12 which increase the magnitude of the mechanical energy. The boosters 12 are connected to separate (ultra)sonic horns 13 which are brought into contact with and apply a predetermined pressure to the plies 40 to be spliced by hydraulic or pneumatic cylinders 14. These plies 40 are supplied by a conveyer belt 20. To ensure that the pressure applied during splicing is uniform, the belt 20 is backed by plates 30 supported by an air bag 31.

Patent NL-192151-B (NL)
IPC: G11B20/12
Filed: 1986-02-24
Abstract: A method and apparatus for storing and reading digital information, in which the recorded information is protected by a double symbol correcting code involving interleaving between the codes and also employing an additional, optional error correcting code. The information is organized in sectors, which are arranged such that following the synchronization and header information sub-header information is provided to indicate different sub-modes of operation of the playback apparatus. During playback, when a first sub-mode indication value is detected, this means the sector contains further error protection information, that is, the optional error correcting code, for which purpose a special decoder is activated. When the sub-mode detector detects a second sub-mode indication value, this means that further user information is present at the location where the optional error protection information would have been, and the special decoder is not activated.
