Patent ES-351234-A1 (ES)
Title: Improvements in or relating to the Cooling of Rolls
IPC: B21B27/10
Filed: 1968-02-26
Abstract: Apparatus, suitable for cooling or lubricating the roll of a rolling mill, comprises a curved member 30 which extends longitudinally of the roll and carries pads which contact the roll and which define passageways through which cooling or lubricating liquid can flow. The liquid, which is conveniently water, or oil and water, is supplied through a pipe to the rear of the member 30 and, after being guided through channels and then apertures in the member and through the passageways to the roll surface, it exits through further pipes 37. Extending longitudinally between the pads are blades of plastics material which scrape the roll surface and prevent the formation of a film of steam on the surface. Each end of the member 30 is carried by a threaded rod 25 which carries a bracket 22 attached to a fixed support. Adjustment of a spring-loaded nut 27 permits the loading of the member 30 against the roll to be varied.

Title: Process for continuously incorporating modifiers into molten glass
IPC: C03B5/173
Filed: 1970-02-20
Abstract: Solid particulate material such as colorant to be added to and homogenized with molten glass in a melting furnace, is deposited into a reservoir over and subjected to the hot atmosphere of the furnace and thereby melted.

On the planar surface the filaments spread out into a smoothly and downwardly flowing stream of uniform minute thickness which passes into the molten glass without turbulence and without entrainment of air bubbles. If required, additional heating means for the solid particulate additive or frit, may be provided.
Patent ES-378828-A1 (ES)
Title: Multistation analytical photometer and method of use
IPC: G01N33/48
Filed: 1970-04-20
Abstract: In a rotary cuvette photometric analyser, a rotary disc 11 has a multiplicity of first chambers 12 connecting with radially outwardly disposed second chambers 14 connecting in turn withlower third chambers 16, for providing soild free samples to surrounding cuvettes 9. The first chambers are adapted to receive liquid samples and reagent. On slow spinning of the disc, both liquids are transferred by centrifugal force to second chambers 14, where they are centrifuged to yield a precipitate. A transparent cover 18 prevents leakage of liquid from the chambers 12, 14. The supernatent liquid flows down bores 15 into third chamber 16 when the disc stops rotating. The supernatent is then transferred into cuvettes through bores 17 by further rotation of the disc. The supernatent is then diluted in the cuvettes, and its transmittance measured by light passing through two transparent rings 4, 6 and bores in keeper plates 2, 8, whose intensity is measured by a detector 22 incorporating a photomultiplyer. Current from a tachometer 23 and revolution detector 26 is fed to a signal generator 24, so that pulses of light from each cuvette can be distinguished by a pulse scanner 25 during each revolution, and then fed to a pulse peak readout 27. The analyser may be used with two liquids which do not form a precipitate when mixed in the second chambers 14, but react slowly and require prolonged incubation. In this case, the disc is kept rotating slowly until the reaction is complete.
