Patent ES-8105804-A1 (ES)
Title: Cutting apparatus for sewing machines
IPC: D05B65/02
Filed: 1980-09-19
Abstract: The invention pertains to a cutting apparatus for sewing machines disposed downstream of the machine's sewing zone. The apparatus includes a cutting blade and a protective guard for the blade both of which have independent actuating devices. The actuating devices are effective in moving the guard and blade between one position which provides clearance for the workpieces being advanced along the machine's work surface and another position where they are operatively associated with the workpieces. A timing element is operatively associated with both actuating devices and is effective in causing the protective guard to be moved toward the workpieces prior to movement of the blade.
Patent ES-8200302-A1 (ES)
Title: Coiling yarns
IPC: A23G3/02
Filed: 1980-09-26
Abstract: A hollow multi-layered yarn package includes layers of mutually concentric annular yarn courses (36) in which the yarn passes between successive courses at regions (37) which are staggered about the axis of the package. The package is produced by coiling the yarn on a yarn coiler and then transferring the coiled yarn to a rotating yarn receiver (32). To form the concentric annular courses the coiler is moved towards or away from the axis of rotation of the yarn receiver (32) after each successive annular course has been formed.

Patent ES-8401653-A1 (ES)
Title: Combined radio and magnetic energy responsive surveillance marker and system
IPC: G08B13/24
Filed: 1982-09-03
Abstract: A surveillance marker has a semiconductor connected between arms of a dipole antenna, one arm being of non-ferrous conductive material and the other of high permeability low coercivity material such as permalloy. Higher coercivity magnetizable pieces are disposed adjacent the low coercivity arm, and all is sandwiched between paper or other insulating layers. The marker is detected by a combination of RF field and low frequency magnetic field generating and receiving units that energize a master alarm only when both units simultaneously detect the marker signals. Magnetizing the higher coercivity pieces suppresses a signal that would otherwise be reradiated by the marker from the high permeability arm thereby rendering the marker undetectable.

Title: Antitheft alarm device e.g. for suitcase
IPC: G08B13/14
Filed: 1982-12-29
Abstract: EP--98913 A (+22.3.82, 13.4.82, 23.8.82 (2), 14.10.82, 7.12.82, 15.12.82, 21.12.82 (3) 24.12.82 (2) -ES- 510664, 511397, 515186, 515187, 516506, 518012 518238, 518343 (5) (6), 518567, 518568)  The device is disposed on or in an object to the protected and the conductive sphere is caused to be positioned in a given zone (D1) where it causes closure of either switch of a pair of switches but not both switches simultaneously. The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)

Title: Engine oil level detecting device
IPC: G01F23/00
Filed: 1983-02-18
Abstract: A device for measuring the oil level in the sump of an internal combustion engine. A resistive wire probe extends into the oil contained in the sump.

Patent ES-8503166-A1 (ES)
Title: Integrated optic device.
IPC: G02F1/125
Filed: 1983-09-29
Abstract: In the case of an optical beam coupled to a waveguide (2) of an integrated optic device by means of a prism coupler (3) or a grating coupler for maximum coupled optical energy the coupling angle ( theta ) must be strictly controlled. This is achieved by controlling the temperature of the device, rather than the conventional mechnical control techniques, since theta is dependent on various parameters, such as the refractive indices of the prism and waveguide, which are themselves temperature dependent. Dynamic control of the optical throughput of the device is thus achievable by means of an electronic feedback loop circuit controlling the temperature of the device accordingly. A solid state laser printer may include a surface acoustic wave device based on such an integrated optic device as a laser beam deflector. A laser beam modulated with the information to be printed is coupled to the waveguide of an acoustic wave device and acoustic waves generated in the waveguide employed to scan the light beam over a photo-sensitive surface moving transversely to the scan direction.
Patent ES-8406739-A1 (ES)
Title: Zero crossing circuit.
IPC: H01H51/12
Filed: 1983-10-21
Abstract: A microprocessor-based zero crossing circuit produces in response to an input command provided by closure of a switch (18) an output signal (13, 14) which is synchronised with the zero crossing points of an a.c. supply and includes a predetermined delay. By this means the output signal (13, 14) may be used to operate or control operation of, for example, a circuit breaker for the a.c. supply in order to minimise contact arcing. The circuit is useful in an electricity supply meter when the input command on input 12 is generated by a credit or prepayment mechanism which acts to cut-off an a.c. supply on expiry of credit. Following a cut-off command on input 12 the circuit produces the synchronised output signal (13, 14) appropriately delayed to take into account the operating time of the circuit breaker so that its contacts (20, 21) open as nearly coincident as possible with a zero crossing point of the supply.

Title: Equalizing circuit for series-connected switches.
IPC: H02H7/10
Filed: 1984-05-29
Abstract: An equalizer circuit for switches connected in series between a voltage source (21) and a load (16), each switch (4, 11) being connected in parallel with a respective equalizing capacitor (2, 9) via a respective diode (7, 8). The circuit further includes a transformer (20) having a plurality of windings (6, 13) connected in series with respective diodes (5, 12), with each switch having a respective winding-diode series connection connected in parallel therewith. In this manner, electrical energy initially stored in the capacitors is transferred to be stored in magnetic form by the windings when the switches are closed and is re-used when the switches are opened to accelerate charging of the less charged capacitors until all the capacitors reach the voltage of the most charged capacitor. The invention is particularly applicable to semiconductor switches such as transistors or gate turnoff thyristors connected in series and needing protection against exposure to excessive voltages due to differences in switching times between switches.
