Title: Rotary diesel engines equipped with a turbo-supercharger
IPC: F02B37/00
Filed: 1965-05-29
Abstract: A rotary-piston diesel engine as described in Specification 1,107,081 in which each working chamber includes a cylindrical combustion chamber 9, Fig. 1, extending the full axial extent of the piston 3, an air inlet valve 18, Fig. 2, and an exhaust valve 19, to create turbulence in the working chambers by the movement of the centre of gravity of the chamber in its cyclic increase and decrease in volume, by the rotation of air in the combustion chamber and by the curved and tangential positioning of each inlet duct with respect to its working chamber includes a helicalcentrifugal turbo-supercharger 40 driven by a helical centripetal turbine 37 by the exhaust gases. Each combustion chamber 9 is connected by a lagged pipe 34 controlled by a blow-off valve 27 to drive the turbine 37 which in turn drives the rotor 40 of the supercharger 40. With five working chambers there are five pipes 34 equally spaced around the turbine and five pipes 42, leading one to each inlet duct. The engine includes a flywheel 15 and a counterweight 16 at either end of the engine shaft. The inlet, exhaust and blowoff valves are opened and closed in timed sequence by cams and linkage driven from the engine shaft. The inlet valve remains open from top dead centre with a conventional angular lag of from 30 to 60 beyond bottom dead centre, then closes and remains closed together with the exhaust and blowoff valves during compression and part of expansion until pressure has been reduced to 40 to 55 p.s. i. whence the blow-off valve 27 is opened to supply the turbine with exhaust gases. At substantially bottom dead centre the exhaust valve 19 also opens and for some time inlet and exhaust valves remain open with the exhaust valve closing just prior to top dead centre. Simultaneously with the opening of the exhaust and blow-off valves the inlet valve is partially opened to provide scavenging or alternatively a small scavenging valve may be provided which may also be utilized to cool the rotor at its hottest point.

Title: Machine for heat sealing continuously moving work-material sheeting in the manufacture of bags of plastics materials
IPC: B31B50/64
Filed: 1968-08-17
Abstract: Machine for heat-sealing continuously moving workpieces of plastics film e.g. tube sections for making bags, has a plurality of heatsealing jaw sets secured to endless conveyer chains, each heat-sealing jaw set being arranged to be energized in dependence on the machine cycle and to be de-energized by means of a timing element after a predetermined interval of time. Tubular material is cut into bag lengths S, each of which is fed at position 37 into a pair of retaining and heat-sealing jaws 8-37, mounted on conveyer chains 2, 21. Heat-sealing begins when the workpiece enters on the lower run of the conveyer. The retaining and sealing jaws are guided by rollers in suitable guide rails and are closed by a pair 38, 381 of a series of pairs of rails, acting on rollers 89, 891 to close the heat-sealing jaws 86, 91 (Figs. 3-5, not shown). The rails 38, 381 are pivotally mounted on levers 58, 59 60, 61 &c. and acted upon by a respective piston-cylinder unit 63-72 through a corresponding beam 82. These units are controlled by respective cams 145-154 driven by the machine which cams also operate time relays in the heating circuits, to interrupt the heating current after a pre-set time interval. Current is conveyed to the heating jaws through current collectors 101, 1011 from a common neutral bar 102 and a respective bus-bar 48 of a series of bus-bars 48-57. After the heat sealing the heating jaws are separated through release of the rails 38, 381 by the piston-cylinder unit. Subsequently the retaining means are opened and the bag deposited on a delivery container. The arrangement is such that each corresponding cam, piston-cylinder unit, pair of rails and current collectors control one of a number (10 as shown) of heat-sealing jaw sets along the lower run of the conveyer and as each set leaves said control a further set is introduced at the beginning of the run, thus enabling, say 10 out of say 30, heat-sealing jaws to be operative at the same time.

Patent ES-415824-A1 (ES)
Title: Blade for applying a flowable substance to a moving article
IPC: D21H23/00
Filed: 1973-06-12
Abstract: The coating machine employs a blade which has a chamber between the blade proper and the moving article to receive a pressurized supply of a flowable substance. The blade is pressed perpendicularly towards the path of the moving article under a force which is opposed by the pressure of the flowable substance to cause the blade to float on a cusion of the flowable substance. This force can be generated by directing the flowable substance into a thrust chamber on the far side of the blade while the chamber on the near side of the blade receives the substance at a lower pressure via restricted passageways. The difference in pressures provides the resultant thrust force.
Patent ES-419083-A1 (ES)
Title: Hydrogen fluoride recovery process
IPC: B01D47/00
Filed: 1973-09-26
Abstract: Crude hydrogen fluoride gas is fed into a gas cooler wherein the gas is cooled by evaporating a recirculating liquid stream containing liquid hydrogen fluoride. This liquid stream removes sulfur impurities from the crude gas. The recirculating stream is recycled through the gas cooler a sufficient number of times until the sulfur impurities build up to a particle size that is easily removed by conventional liquid-solid separating techniques such as filtration. A portion of the recirculating stream is continuously drawn off and the sulfur particles are removed. The cooled gas is taken off overhead and subsequently condensed to form crude liquid hydrogen fluoride. The removal of the sulfur in the gas cooler prevents the buildup of sulfur coatings on the heat transfer surfaces of the condenser and subsequent processing equipment.
