  • Patent number: 4067647
    Abstract: A dual film strip projector projects images onto at least one screen from a pair of film strips, each of which is advanced in programmed timing independently of the other. The film strips are contained in a cartridge that is readily insertable in the projector, and the timing of the advance of the frames of each film strip is automatically controlled by control signals recorded on a magnetic tape in another cartridge insertable in the projector. The projector includes dual illumination systems, projection lenses and film strip advancing devices. Operation of the projector is entirely automatic in that the control signals on the magnetic tape operate the pair of film strip advancing devices.

  • Patent number: 4057231
    Abstract: The invention relates to a process for automatically deslagging a cupola furnace and to an improved cupola furnace using this process.According to the invention the bottom of the crucible is permanently connected to atmosphere via a siphon sill whose level is determined so that the interface between pig iron and slag is sometimes above and sometimes below this sill. The side wall of the cupola furnace has on the one hand a taphole for the pig iron opening into the crucible level with the hearth and which can be sealed with a plug and on the other air blowing tuyeres in the upper part of the crucible, as well as a siphon linked with the crucible for the supply thereof by means of a passage whose lower edge is adjacent to the bottom of the crucible and whose upper sill extends below the maximum permitted pig iron level determined by the siphon outflow, whereby the maximum permitted slag level is located below the nozzles.

  • Patent number: 4048344
    Abstract: A process for preparing a tea extract is disclosed in which a heated aqueous tea slurry is confined in a first zone separated from a second zone by a liquid-pervious barrier, a body of extraction liquid is maintained in said second zone to permit diffusion of tea solubles from the tea slurry into the extraction liquid, the volume of the slurry being 0.5 to 2.5 times the volume of the body of extraction liquid. After a suitable contact time, the extraction liquid and slurry are removed from the zones and the tea solubles diffused in the extraction liquid and present in the slurry ultimately are combined, intervening processing including, for example, stripping and removing of aromatic volatiles before a final extract product is provided.
