Patent ES-314773-A1 (ES)
Title: Dust collector
IPC: B01D46/04
Filed: 1965-06-30
Abstract: A plurality of outward-flow bags 22, of a gas filtering apparatus, are cleaned periodically by shutting off the filtering flow, at outlet 12, opening a valve 18 causing a gentle reverse flow so that the bags collapse, and then directing charges of compressed gas upwardly from nozzles 26b, 27b, 28b whereby the bags are re-expanded, the charges being reflected down the bags again by their closed upper ends, the resulting shaking of thebags removing dust therefrom which falls into hopper 6. The nozzles are spaced along conduits 26, 27, 28 supplied through quick-acting valves (Fig. 2, not shown), operated together or in sequence, which open for periods which determine the degree of re-expansion of the bags, which is set to correlate with the setting of valve 18. Outlet 12 communicates with an induction fan 16, and valve 18 with atmosphere or with the high-pressure side of fan 16. Conduits 26-28 may have down-curving open ends (Fig. 3, not shown) to remove solids from the conduits. A number of housings 1 may operate in parallel from one dirty gas supply 11, and each is cleaned in turn or on accumulating sufficient dust. In another embodiment (Fig. 4, not shown), the bags (221) are tubes open at both ends, dirty gas is supplied to a common inlet chamber (37) at the upper ends by a "forced-draught" fan (40), and initial collapse of the bags is induced by closing the inlet valve (42) to the housing and opening a valve (44) which connects the hopper with the lowpressure side of the fan (40). The bags are then all re-expanded together, the inlet chamber reflecting the charges back again.

The bricks may have tongued-and-grooved ends to ensure location with adjacent bricks.
Patent ES-350594-A1 (ES)
Title: Polishing of glass
IPC: B24B7/24
Filed: 1968-02-17
Abstract: Apparatus for polishing the surface of a glass article comprises a rotatable polishing head 28, support means 18 for the article, and drive means 14, 17, 26 operative to cause relative movement between the head and support means such that, in a polishing period of normal duration, each part of the surface of the article is polished to substantially the same extent but the drive is indeterminate at least to an extent such that in a polishing period of normal duration the polishing head does not repeatedly follow exactly the same path over the surface. The support means 16 consists of a table 16 which is mounted on a carriage 13 for oscillating movement about a vertical pivot by a piston- and-cylinder unit 17. The carriage has rollers 12 engaging guideways 11 in a bed 10 and is reciprocable by a piston-and-cylinder unit 14. A pillar 21 is disposed on each side of the bed, the pillars being interconnected by beams 22 supporting rails engaged by the wheels of carriage 24 carrying the polishing head 28. The carriage is reciprocatable along the rails by a piston- and-cylinder unit 26, and the head 28 is rotatable by a toothed belt driven from an electric motor 30. The spindle of the head is spliced or keyed to a bush in the carriage 24 and is vertically movable by a piston-and-cylinder unit 31. The periods of reciprocation of each unit 14, 17, and 26 differs from the others so that during oscillation of the table 16 within limits determined by switches 52 and reciprocation of the carriage 13, 24, the polishing head does not follow repeatedly the same path over the article being polished. The reversing of the units 14 and 17 is controlled to avoid excess polishing of the edges of the article by four proximity switches 44 which are adjustably carried by the carriage 24 and respond to metal strips carried by flexible supports mounted on the table 16 a predetermined distance from the edge of the article being polished. At least one of the units 14, 17, 26 is pneumatic and the others may be pneumatic, hydraulic, or unsynchronized electric motors. The polishing head 28, Fig. 6, consists of a metal disc 32 carrying a circular pad 33 formed on its lower surface with grooves 34. The disc is secured to a plate 35 which is urged by springs 41 on bolts 39 against a ball 36 located in conical recesses in the plate and a housing 37 secured by a key 38 to the spindle 29, a gap being provided between the plate and housing to permit tilting of the head relative to the axis of the spindle.

Title: Eccentric wheel accumulators
IPC: B65G47/28
Filed: 1974-06-26
Abstract: This is an improvement in an accumulator conveyor of the type in which the application and release of the propelling force is effected through changes in the vertical positioning of a propelling member supported on rollers having a flattened portion. A particular feature of the invention is the provision of pairs of coaxially adjacent rollers, eccentric in cross section and rotatable relative each other between a stationary dwell position when positions of least radius are in phase with each other and a drive position wherein portions of least radius are out of phase with each other. In the drive position, the rollers rotate jointly together in out of phase relationship, forming a circular roller maintaining support for the propelling member at a constant vertical position.

Patent ES-443665-A1 (ES)
Title: Means and method for controlling the occurrence and the duration of time intervals during which sparks are provided in a multicylinder internal combustion engine
IPC: F02P15/10
Filed: 1975-12-18
Abstract: A control system controls the occurrence and the duration of time intervals during which sparks may be provided in the cylinders of an internal combustion engine driving a crankshaft as a function of operating parameters of the engine. Sensors sense parameters such as the vacuum in the carburetor, the position of the throttle and the torque of the crankshaft and provide corresponding signals. A distributor provides a pulse signal. Each pulse in the pulse signal has a width corresponding to a predetermined rotational displacement of the crankshaft. A counter with associated logic circuitry counts clock pulses in an up-direction during the occurrence of a pulse of the distributor pulse signal. When the counter counts down to a particular count, a decoder triggers a one shot multivibrator to provide a pulse, each pulse provided by the one shot multivibrator corresponds to the start of a spark time interval. A preset circuit receives the sensed parameter signals and presets the decoder so as to select the particular count to control the time of occurrence of the spark time intervals. A second counter is loaded with clock pulses at a reduced rate, simultaneously with the loading of the first counter. During the unloading of the first counter, the second counter is inactive. However the second counter is then unloaded at a faster rate when the spark time interval is started. Upon reaching a zero count, a spark time interval is terminated. An ignition system provides sparks to cylinders during each spark time interval.

Title: Injection blow molding process
IPC: B29B11/08
Filed: 1976-02-20
Abstract: In an injection blow molding process for making plastic receptacles, an injection station is provided for injection molding a parison of selected configuration. An expansion and blowing station follows for initially expanding the parison to a predetermined length, and thereafter the parison is blow molded into a predetermined lateral and final configuration to thereby biaxially orient the molecular structure of the parison. An ejection station is provided for removing the finished product from the apparatus. The parison is transferred along a first path away from the injection station, along a second path which is normal to the first path and then along a third path parallel to the first path to the expansion and blowing station. At the same time, a finished product is transferred from the blowing station to the ejection station along a corresponding path. The blow molding station is adjustable or interchangeable so that different size containers can be molded without changing the size of the injection cavity. The apparatus may also be designed with a core pin arrangement to insert a liner within an outer plastic parison shell prior to the blow molding process at which time the liner and parison shell will weld together to form a finished container. Close temperature control is provided with the parison being maintained with a desired temperature range to retain the biaxial orientation. Finally, the apparatus is designed to facilitate removal of the finished product to further work stations for subsequent work thereon.
