Patent ES-486655-A1 (ES)
Title: Multifrequency receiver
IPC: H04L27/26
Filed: 1979-12-06
Abstract: Reception of valid two-out-of-N incoming multifrequency signals is realized by employing a multifrequency detector (FIG. 1, 102) including a plurality of filters (FIG. 2, 202-1through 202-N) and a corresponding plurality of comparators (206-1 through 206-N). The comparators are jointly responsive to output signals from the filters and to a threshold level (RMS REF) dynamically generated (via 204) in response to the incoming signal for generating output pulse signals (103-1 through 103-N) representative of multifrequency tones which exceed the threshold level (RMS REF). The pulse signal outputs (103-1 through 103-N) from the multifrequency detector (102) are evaluated (by 105) to determine whether two and only two tones are present which meet a prescribed criteria. The criteria is that each tone be present for at least a predetermined minimum portion of a prescribed sampling interval and that both tones be present for at least a predetermined number of consecutive sampling intervals. Out-of-band signals are rejected while increasing receiver sensitivity to inband signals by maintaining the peak amplitude of outputs from the filters generated in response to a single tone incoming signal having a frequency midway between the center frequencies of adjacent ones of the filters (202-1 through 202-N) in prescribed relationship to the magnitude of the threshold level (RMS REF) generated in response to the single tone incoming signal (see FIG. 4). In one example, the peak amplitude of the filter outputs is substantially equal to the magnitude of the threshold level (RMS REF, FIG. 4).
Patent ES-8101726-A1 (ES)
Title: High pressure diaphragm pump.
IPC: F04B43/00
Filed: 1979-12-07
Abstract: A high pressure diaphragm pump has a diaphragm 2 which carries a valve poppet 7 on its upper surface. The valve poppet 7 fits into a flared portion 6 of a passage 4 for hydraulic fluid. When the diaphragm 2 restores to the position shown in Figure 1, the valve poppet 7 closes the passage 4 and prevents the diaphragm being punched back into the passage by excessive fluid pressure on the opposite side of the diaphragm. The diaphragm is made with flat edges 10, 11, 12 so that it can easily be mounted in a housing by means of three easily formed components 13, 14, 15. A small axial compression between components 14 and 15 is all that is necessary to keep the diaphragm in place during operation.
Patent ES-489163-A1 (ES)
Title: Billet transfer from supply on to roller conveyor - by slide jaw picking up at top and depositing near bottom of inclined track
IPC: B65G59/06
Filed: 1980-03-04
Abstract: The mechanism transfers individual heavy long objects, partic. billets, from a supply and along an inclined track to a longitudinal conveyor such as a series of rollers. It comprises a transfer slide with support jaw which receives an individual billet from the supply when the slide is in its uppermost position along the track and deposits it on the rollers as the slide travels down the track to its lowermost position. The slide may be reciprocated by the piston rod of a hydraulic cylinder actuator, which may be coupled to the slide via pivoted link arms.
Patent ES-8102868-A1 (ES)
Title: Sliding gate valve
IPC: B22D41/38
Filed: 1980-05-29
Abstract: A sliding gate valve of the type in which refractory gates (17, 17') are sequentially disposed in operative position beneath the pour opening from a teeming vessel, such as a tundish, is effective to throttle the metal flow stream from the vessel. Means (84) for positioning the gates in order to control the degree of throttling of the flow stream are independent from the means (74) for disposing the gates in their working position within the valve mechanism whereby the flow stream can be terminated without adjusting the throttling configuration of the valve. Means are provided, when the valve employs a pour tube (19) attachment, for selectively changing gates and pour tubes in unison, or independently from one another. The valve mechanism and its replaceable refractory components are designed for the supply of fluids for cooling these members and for the injection of inert gas to stir molten metal in the flow passage during holding periods.

Title: Circuit arrangement for disabling keys of a control device for an signal box
IPC: B61L21/04
Filed: 1982-04-07
Abstract: The subject matter of the invention is a circuit arrangement for disabling keys of a control device in an signal box in which, in addition to manual control operations, triggering of signal box processes is also performed by means of automatically operating devices (self-signal box mode, number signal box console, computer control, remote control). The deactivation of the keys takes place automatically during the access of the automatic devices and safeguards the automatic signal box mode against faults resulting from simultaneous activations of keys. In order to safeguard the signal box console against being operated by unauthorised persons, the deactivation of the keys can also be performed by the operator for example by means of a breaker mechanism, the automatic signal box mode continuing undisturbed.

Title: Head for driving timber crate-staple - uses orbital U=section press to bend wire retained by mandrel and pushed away by trailing pusher sliding between legs
IPC: B27F7/28
Filed: 1982-04-23
Abstract: The stapling head is used to make crates, with a cutting and bending press (8,9) which acts with a counter cutter (24) cum wire (27) guide and a retractable wire-retaining mandrel (30). The latter acts with a staple-pusher (10) to which the re-action is provided by an anvil (35) applied to the timber. The bending press may have a 'U' section with the staple pusher fitting between its legs, both components having a curved profile whilst being built onto separate levers (5,6) with a common fulcrum (2). The locus of the profiles coincides with the fulcrum, the fulcrum axis is normal to the staple drive (F), and the axis is offset so that the repose position of the head is outside the swept path of the bending component and the pusher. The drive for the levers ensures sequential action and the bending component leads the pusher.

Patent ES-8305127-A1 (ES)
Title: Weighing apparatus such as scales for weighing people.
IPC: G01G19/52
Filed: 1982-07-24
Abstract: The long levers (3a and 3b) are capable of pivoting at one of their ends on a knife (2a and 2d), and two short levers (4a and 4b) are also capable of pivoting at one of their ends on a knife (2b and 2c). At their other end, the short levers (4a and 4b) are coupled by means of a coupling system (9 and 9a) to the long levers (3a and 3b). The other ends of the long levers (3a and 3b) are engaged at a very short distance one from the other with a force transmitting system (29) which is suspended on the free end of a flat spring (18, 21) provided with gauges (20) for measuring the bending of the spring. The gauges are connected to a read-out system through an electric circuit. The force exerted by the long levers (3a and 3b) is applied on a force transmitting system at a very short distance from the plane of symetry of the flat spring (18, 21). As a result, the force received by the flat spring is practicaly vertical and equal (or proportional) to the force exerted by the load on the tray, even when the load is unevenly distributed on the tray or when the tray is slightly deformed under the load the accuracy of the measurements is therefore not affected in the above mentioned adverse circumstances.

Title: Method and device for measuring the velocity of moving objects.
IPC: G01S17/42
Filed: 1982-12-17
Abstract: The invention relates to a method and apparatus for measuring the velocity of a moving object. Measuring beams composed of sequences of optical pulses are directed towards the object which is to be measured and follow such object. Based upon transit time measurements of reflected pulses there are formed distance values and distance difference values. While taking into account the time interval of the pulse sequence there are computed velocity measuring values and velocity values computed from homogeneous groups of values are displayed as reliable velocity values. By means of a measuring beam deflection system there are directed measuring beams into defined solid angle sectors towards the object which is to be measured, and reliable velocity measuring values computed from homogeneous groups of measuring values from the measuring channels correlated to the individual solid angle sectors are displayed as binding or valid velocity measuring values if there is present a confirmation of the value from further solid angle sectors.
