Patent GB-2278430-B (GB)
Title: Heat exchanger
Inventor: BOWMAN JOHN EDWIN
IPC: B21D53/04
Filed: 1994-03-25
Granted: 1997-04-23
Abstract: A heat exchanger comprises a plurality of substantially similar plates 10, with a pair of ports. Each plate is turned 90 DEG  in the same direction relative to the adjacent one so that the ports align to provide a pair of separate series flow paths which are interleaved between the plates. The angular alignment of the ports is controlled by the regular polygon shape of the plates. The plates are clamped together and sealed for example by furnace brazing. The ports are defined by oppositely extending stub tubes 54, 56. The plates preferably have dimples or other projections in opposite directions from both faces. Also disclosed is a method of producing substantially identical heat exchanger plates which have different patterns of projections (42, figure 1). The different patterns being obtained by locating or not locating projection forming punches in recesses in the dies used to form the plates. <IMAGE>

Title: Sound-permeable cover, in particular for loudspeakers, as well as method for making said cover
Inventor: JUST GUENTER
IPC: B29C45/14
Filed: 1992-02-14
Abstract: Sound-permeable cover, especially for loudspeakers, having a flat, sound-permeable material and a grid-like plastic structure on each of the two sides of the material, the two plastic structures being connected together substantially only in the region of the contact surfaces of the grid webs 1, 2 through the interspaces of the filaments 6 of the sound-permeable material 3 and to the sound-permeable material 3 to form a one-part body 1,2,3. One of the plastic structures consists of material that the sound-permeable material 3 has penetrated. The process for manufacturing a sound-permeable cover provides that the sound-permeable material is placed between two half-moulds for the grid-like plastic structures in an injection moulding machine, that plastic is subsequently injected from one side of the sound-permeable material and the feed of further plastic is stopped when the plastic has penetrated the sound-permeable material and has also filled the opposing mould. <IMAGE>
