Patent ES-476411-A1 (ES)
Title: Driving circuit for piezo-electric multimorph transducer
IPC: H01L41/04
Filed: 1978-12-28
Abstract: A piezo-electric transducer, such as, a bi-morph leaf, comprised of a pair of piezo-electric elements which are oppositely poled in opposite directions and interposed between inner and outer electrodes with each element being bonded to the other at the respective inner electrodes, is provided with a drive circuit applying a drive voltage across the outer electrodes, one of which is desirably grounded, for deflecting the transducer, and which clamps the voltage at the bonded together inner electrodes to a relatively small maximum value at least in response to a polarity of the drive voltage opposed to the direction in which one of the piezo-electric elements is poled so as to avoid substantial depolarization of at least that one element. The foregoing arrangement is particularly desirable in an apparatus in which a magnetic head is moved along a track on a magnetic tape or other record medium for reproducing information signals recorded in such track which the bi-morph leaf supports the head for deflecting the latter in a direction transverse to that along the track in response to the drive voltage.

Title: Valve packing
IPC: F16K3/26
Filed: 1979-10-23
Abstract: A two-member valve plug comprises a lower plug member 23 and an upper plug member 22 which are in a generally axially spaced relation on the valve stem. Packing 35 is held in a snug-fitting condition between the lower and upper plug members by an axially resilient member 41 which acts between one end of the valve stem and the valve plug to urge the lower and upper plug members together. When the two-member valve plug closes a fluid passage, a force is transmitted by the valve stem directly through the upper plug member to the packing to form a leak-tight seal for the valve plug. The stem force is also transmitted through the packing and lower plug member to generate a seating force between the valve plug and a seat 17.

Patent ES-8306648-A1 (ES)
Title: Random droplet liquid jet apparatus and process.
IPC: B41J2/06
Filed: 1982-02-03
Abstract: Fluid or liquid jet marking apparatus and process wherein the treating fluid or liquid (10) is in the form of ink, dyestuff or other printing, marking or coloring medium, is delivered under pressure to an array of jet orifices (14) from which the medium issues continuously as streams (16) that break randomly into discrete droplets in flight. The moving random droplets are selectively charged as they pass through a selectively energizable electrostatic field (18). The paths of charged droplets are controlled by a deflection means (20) which establishes a second electrostatic field through which the droplets pass. Depending on whether the droplets are charged, they are either caught by a collector (22), or impinge on a receiving substrate such as a textile, paper or any other desired medium, product or substance. In the apparatus, the streams (16) break up randomly into droplets. Since the apparatus is not provided with a separate stimulator, vibrator or perturbation device, the orifice plate can have virtually an unlimited cross-machine length. It has been found that by controlling certain equipment parameters, such random droplet breakup can occur within a narrow distribution around a mean droplet size to produce results very much the same as with perturbed systems that use separate, regularly cyclical varicosity inducing means, and in many cases are superior to perturbed systems in a large variety of applications as the lenght of the orifice plate is not limited in size. The undesirable effects of droplet to droplet size and spacing variation become narrowed with increased pressure on the fluid or liquid supply and decreased diameter of the jet orifices.

Title: Automatic shut off circuit for fluid nozzle - uses air cooled temp. sensitive resistor whose temp. increases when fluid restricts air flow
IPC: G01F23/24
Filed: 1983-01-07
Abstract: The hand held nozzle for filling oil reservoirs on mechanical equipment has a manually operated on/off valve in the flow line. A magnetic proximity detector senses that the valve is in the OFF position and its output controls a relay with multiple contacts. Adjacent to the outlet nozzle is a compressed air pipe outlet in which a positive temperature coefficient resistor (6) is mounted. This is connected to the inverting input of an op. amp. (22) while a reference voltage (23) is connected to the noninverting input. When the oil reservoir is almost full the temperature at the resistor increases due to restricted air flow. The op. amp. output drives a relay (R1) driving transistor (27) to issue a control signal to an electrovalve. An LED (28) visually indicates the end of the filling cycle.

Patent ES-8503549-A1 (ES)
Title: Method for facilitating the subsequent debarking of trunks by friction
IPC: B27L1/00
Filed: 1984-04-12
Abstract: It is possible to reduce the time required for debarking trunks by friction, for example for dry debarking in a drum for debarking trunks intended for conversion into wood pulp, by means of the prior processing (treatment) of the trunks. During combustion of the bark which has been removed, the latter must be as dry as possible. According to the present invention, the pretreatment, in particular of trunks which are difficult to debark, is improved in such a way that adhesion of the bark to the wood is greatly reduced without it being necessary to supply water to the trunks. This is achieved in that rigid beaters 9, which are joined in an articulated manner to a shaft 13 of a driven rotor which extends essentially transversely to the longitudinal direction of the trunks, are made to collide against the trunks 5 over an area and with an impact force which are sufficient to weaken the union between the bark and the wood through fatigue and/or transportation of moisture, induced mechanically, from the inner bark to a meristem layer which is located between the bark and the wood and which joins them together. The arrangement for pretreatment preferably includes at least one pair of rotors which has rotors 7, one above and one below, of a working width such that it is possible to process simultaneously a plurality of trunks placed side by side.
