Title: Pneumatic dust collection system
IPC: B01D46/71
Filed: 1971-08-20
Abstract: A pneumatic dust collection system includes a housing which defines a dust-air chamber portion, a flushing air chamber portion and a clean air portion arranged one above the other. A separating wall between the flushing air chamber and the dust-air chamber is penetrated by fittings for suspending filter hoses in the dust-air chamber portions which communicate through the fittings into the flushing air chamber. A connecting tube extends from the clean air chamber into the interior of each filter hose fitting and the filter hose which is carried thereby and defines an annular flow space between the interior of the hose and the flushing air chamber. This annular flow space may be closed off by an inflatable member which is disposed at the connection of the fitting to the separating wall. At this annular space the connecting tube includes a widened portion around which the flow is diverted and which is located opposite to the inflatable membrane. The interior of the inflatable membrane is connected to an air pressure line and it is inflated to close the annular flow passage between the interior of the filter hoses and the flushing air chamber. The apparatus includes a control system for controlling flushing air to the flushing air chamber and for filling this chamber before the membrane is deflated. An over and underpressure control is connected between the clean air chamber and the dust-air chamber to maintain a selected pressure difference between the clean air chamber portion and the dust-air chamber portion during operation. The flushing air chamber and the control line for supplying the air to the chamber is closed by a rapid depressurizer member which is closed by a signal from a preferred output of a monostable fluid mechanism element. An overpressure in he flushing air chamber causes the depressurizer to open rapidly.

Title: Method and means for regulating the tensioning of workpieces in multi-pass cold-drawing apparatus
IPC: B21C1/12
Filed: 1972-05-30
Abstract: The tensioning of elongated tubular workpieces during transport through a multi-pass cold-drawing apparatus is regulated by changing the speed of discrete electric motors which drive work advancing drums located downstream of successive reducing dies. The speed of the motors is regulated in response to electric signals which are produced by first pressure gauges serving to measure the peripheral forces of the drums and second pressure gauges which measure the retarding forces of the preceding reducing dies. The evaluating circuit employs discrete first and second amplifiers which are respectively connected with the first and second pressure gauges, differential amplifiers each of which receives signals from a first and a second amplifier, rated value selecting devices which furnish preselected signals of constant intensity, and signal comparing circuits which compare the preselected signals with signals furnished by the corresponding differential amplifiers and produce motor-adjusting signals.

Patent ES-417772-A1 (ES)
Title: Carburettors provided with a starting device with an eccentric flap valve
IPC: F02M1/10
Filed: 1973-07-31
Abstract: The eccentric flap valve is situated in an air intake of the carburettor upstream of the intake system for the primary air/fuel mixture, and actuated by the air flow against the effect of a first thermostatic member which tends to close it when the temperature of an element of the engine is below a given limit. A "fast idling" cam cooperates with a second thermostatic member, to partly open the usual throttle member of the carburettor when the flap valve is at least partially closed. Pneumatic means sensitive to the pressure which exists in the intake pipe downstream of the throttle member control the opening of the valve when the pressure diminishes. Stop means with several positions, limit, in variable manner as a function of the position that they occupy, the movement of the pneumatic means. Means sensitive to the ambient temperature control the position occupied by the stop means.
Patent ES-419550-A1 (ES)
Title: Method of preparing a continuously cast ingot for rolling or the like
IPC: B21B1/088
