Patent ES-358668-A1 (ES)
Title: Method of dispensing a refrigerated beverage
IPC: B67D1/00
Filed: 1968-09-30
Abstract: In a method and apparatus for making and dispensing a carbonated semi-frozen confection, a pressurized carbonator 12 is supplied with water by a pump 14, carbon dioxide from a pressurized tank 22, and a freezing- point depressing syrup from a tank 25 the syrup is ejected by gas pressure and pressure regulators 24, 26 ensure that at the carbonator the syrup supply pressure is greater than that of the gas supply. The carbonated liquid passes through a thermostatically-controlled precooler 35 to a freezer 37 having a constantly rotating scraper-stirrer 45, where part of the liquid freezes into pure ice crystals increasing the degree of carbonation and sweeteners of the remaining liquid, there being regulated by controlling the refrigerating system 42 in dependence on a consistency sensor 44. The confection is dispensed through a valve 48 having less resistance to flow than the path between the carbonator and freezer the pressure in the carbonator being hydrostatically transmitted to the freezer when the valve 48 is closed. The freezer has a manual bleed valve 38 to ensure that no pocket of gas accumulates therein. The carbonator is suspended from a loadswitch 19 which actuates pump motor 15 and valves 17, 32 to supply materials switches 21, 27, 31 shut down the refrigerating systems in the absence of any one ingredient. A safety control 41 detects the presence of ice to prevent freezing of the pre-cooler and a centrifugal switch 47 shuts down the refrigerator system 42 if rotation of the scraper-stirrer 45 should cease. The carbonator has a snifter valve 56 which passes gas in either direction but prevents back-flow of liquid so that increase of pressure in the carbonator due to ice formation in the refrigeration system will cause gas to be vented at 55 and a valve 28 enables gas instead of syrup to be delivered to the carbonator to empty it. The carbonator may be replaced by a pre-mix tank filled with all the ingredients of the confection or, for instance, a soft drinks bottling plant.

Patent ES-444487-A1 (ES)
Title: Volatile liquid supply equipment and processes and apparatus for introducing volatile cross-linking agents into polyolefin compounds and for the extrusion of cross-linking polyolefin compounds
IPC: B29C48/29
Filed: 1976-01-14
Abstract: In accordance with an exemplary embodiment of the instant invention, a volatile cross-linking agent such as liquid peroxide is introduced, at ambient temperature and under atmospheric pressure directly into the input of an extruder at the same pressure as a polyolefin compound to be cross-linked. The resulting compounds are put under pressure within the extruder as the temperature increases so that the mixture reaches its definitive shape at the extruder output and may be fed directly into a hot cross-linking enclosure which is maintained under pressure. The peroxide is thus incorporated in a single operation permitting complete control of the ingredients mixed and allowing perfect homogenization of the mixture while defusion and consequent loss of the highly volatile peroxide are avoided. The system for introducing the highly volatile cross-linking agent includes a peroxide storage tank, a filling pump, a feed vessel, an incremental feed pump with a pressure meter, a flow meter and numerous safety features. These elements control the flow, temperature and ambient conditions of the cross-linking agent feed system within a controlled environment to ensure the safe and precise handling of a highly volatile liquid while at the same time controlling the feeding of the liquid as a function of the material processed by the extruder so that the percentage of the cross-linking agent inserted at the input to the extruder remains at a constant, predetermined percentage, regardless of extruder speed variations. Additionally, various additives which are soluble in the volatile cross-linking agent may be introduced within the feed system therefor in sufficient amounts for effecting protection of the resulting polymer without altering the efficiency of the feed system or that of the additive so that the entire process may be carried out at the processing site without initial preparation of various mixtures to be further processed.

Patent ES-450024-A1 (ES)
Title: Apparatus and method for separating opened end flocks from a transporting air stream
IPC: D01G23/08
Filed: 1976-07-09
Abstract: The connecting duct which directs the flock-laden air stream into the chute is provided with a restriction as well as with a ring duct for directing air impulses into the duct via openings on opposite sides of the duct. The restriction causes the air stream to accelerate and, since the air flow is closer to one opening, rather than the other, a reduced pressure is created on that side. This, in turn, causes a pulse of air to travel from one end of the ring duct to the other. The air pulse continues into the connecting duct to deflect the flock-laden air stream towards the other opening. This sequence then continues in rapid fashion to allow an even deposit of the flock in the chute.
