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.

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.

Abstract: This invention relates to the fritting of ceramic products, in particular ceramic products of small or of very small dimensions, for example those intended for use in the electronics industry.A process for fritting ceramic products wherein the products to be fritted which have been preheated to a given temperature are directly exposed to a hyperfrequential electro-magnetic field to raise the products to a temperature which causes fritting.

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.

Abstract: The invention consists an automatic continuous process (kinematic) machine for the manufacture of glass objects characterized in that it comprises, between the blanking drum and the finishing drum, a sliding beam whose sliding motion enables the time period between the vehicles leaving the blanking drum and their entry into the finishing drum to be regulated instantly and precisely while the machine is in operation.

Abstract: This invention relates to a device for non-destructive measurement of the extent to which a surface layer of a material has been affected by a superficial treatment. The device has an emitter of ultrasonic waves and a receiver therefor, the emitter and receiver being movable over the arcuate surface of a semi-cylindrical block which is applied to the material being studied. The emitter and receiver can be moved until the ultrasonic beam is reflected by the surface of the material and measured, means being provided for precise measurement of the angle formed between the emitter and receiver.

Abstract: The invention relates to an apparatus for the electrolysis of water which operates under pressure and can be started up without injecting nitrogen.
