Patent ES-460293-A1 (ES)
Title: Sewing machine
IPC: D05B47/04
Filed: 1977-06-30
Abstract: In a zig-zig sewing machine an automatic adjustment is provided for obtaining the correct values for stitch-length and upper thread tension in sewing fancy seams or button holes by moving a setting knob for such seams to the required symbol. The adjustment is made independently of the existing setting established for stitch-length and thread tension by the use of a pattern selector which in addition to selecting a required pattern activates controls for cloth feed and over-thread tension by a cam and linkage system which transmits movement from the pattern selector directly to an adjustable cullis and thread brake.

Title: Hand bicycle pump with pressure preselection and display means
IPC: F04B49/24
Filed: 1977-07-30
Abstract: A hand bicycle pump of generally cylindrical configuration essentially comprising a pump body adapted to be reciprocated on a pump rod. An air circulation chamber communicates at one end through the compression piston with the compression chamber in the pump body and at the other end via a check valve with a connector adapted to couple temporarily the pump to an inflation valve of an inflatable body, e.g. a tire. The desired inflation pressure is preselected by rotating a sleeve, accessible from outside the pump, having an index, relative graduations along a slot in the pump body. The sleeve varies the spring force exerted against one end of a piston control member, the other end of which is subjected to the pressure inside the inflatable body so that once the desired pressure is reach the control member is displaced axially to bring the compression chamber into communication with the atmosphere. In one embodiment valving is effected by a valve control member which embodies the control member too, and in another embodiment the air circulation tube is axially moveable and a valve disc is provided at the end thereof closest the compression chamber for interrupting communication when the desired pressure is reached. In both embodiments pumping pressure is partially compensated for to prevent untimely communication between the compression chamber and the atmosphere when the pump is reciprocated faster than air can be admitted to the inflatable body.

Patent ES-474780-A1 (ES)
Title: Core box
IPC: B22C7/06
Filed: 1978-11-03
Abstract: A core box, made of two parts, to produce a sand core for foundry moulds, has a recess along the edge of cavity on one of the two halves. A compressible elastic seal, e.g. made of silicone rubber, is laid into this recess before the two halves are joined together. This prevents the production of burrs on the cores which would leave V-grooves, i.e. stress raisers, in the casting, and have to be removed by manual fettling.
Patent ES-475897-A1 (ES)
Title: Disc reproducing system for compensating mechanical imperfections
IPC: G11B3/10
Filed: 1978-12-11
Abstract: The effects of vertical perturbations of a gramophone disc record surface resulting from e.g. record warp and rumble are reduced by sensing the perturbations and compensating therefor by closed loop or open loop means. Thus a reference path adjacent the groove tracked by the main stylus may be tracked, e.g. by a supplementary stylus riding on the lands of the disc surface or photoelectrically. A reference path signal may then be derived by a reference path sensor 104, and this signal is then applied to a preferably closed loop servo 95, 98, 100, 112, 114, 97 which moves the disc 9 itself up and down to tend to null out the reference path signal. Alternatively the compensation is applied by causing the tone arm to track the reference path by a servo technique or by mechanical coupling within the cartridge or electrically by subtracting the reference path signal from the main stylus signal, or by a combination of such techniques.

Title: Instrument carrier enabling star to be tracked continuously - comprises motor driven assembly for rotation and inclination of instrument, depending on star position
IPC: G12B5/00
Filed: 1980-07-04
Abstract: An astronomical instrument is used to follow the course of a star of satellite and is mounted on a carrier which is driven continuously around an axis. This method does not require sensors and is therefore useable during the night or day or during bad weather. An instrument carrier comprises a primary axis in the form of a screw (11) which is rotated in a fixed tube (12) by a motor and reduction gear assembly (15). A nut (18) in the tube moves a drive arm (32) which in turn moves an inclining arm (33) attached to an instrument (45) to allow it to be orientated as a function of the inclination of the star. The instrument is mounted in a pivoting frame (40) which is able to rotate as the motor shaft rotates to permit tracking of the star in two directions.

Patent ES-8106368-A1 (ES)
Title: Fiber optics liquid level and flow sensor system
IPC: G01D5/26
Filed: 1980-11-28
Abstract: A fiber optics level sensor (FOLS) or flow sensor (FOFS) system for use in hazardous environments, process control, and industrial and environmental control applications. The system includes a pair of fiber optic bundles arranged between a remote sensor and a control module. The remote sensor detects the position of a movable vane-which is mechanically coupled to a float in the sensed environment-by means of a transmission gap between confronting ends of the pair of fiber optic bundles. The control module includes a light output device driven by an oscillator which thereby generates pulses of light which are optically coupled to the end of one of the bundles. The end of the other bundle is coupled to a photodetector which generates electrical pulses in response to the returning light pulses. The electrical pulses are amplified and then gated through a sampling circuit which is internally synchronized by means of and in resonse to the oscillator. The gated electrical pulses are then coupled to a staircase generator the output of which is coupled to a comparator. When the output of the staircase generator falls below a predetermined level the output of the comparator changes state to provide an indication that the vane has interrupted the light path in the gap. The output of the comparator controls a relay which is coupled to an external utilization device such as an alarm or a valve control.

Patent ES-8405205-A1 (ES)
Title: Brush wear detector
IPC: H01R39/58
Filed: 1983-08-03
Abstract: A brush wear detector comprised of an L-shaped leaf spring having the outer end of its longer leg mounted on a first insulating member in fixed relationship to a spring support for a self-winding, brush-biasing spring. A second dielectric member is secured to the leaf spring between the ends thereof and projects outward from the leaf spring into engagement with an uncoiled section of a brush-biasing spring. The free end of the leaf spring is held away from engagement with the brush-biasing spring support, thereby being electrically isolated from it, when a new brush is mounted in operating position under the brush-biasing spring. When the brush becomes worn a pre-determined amount the brush-biasing spring moves in a direction away from the second dielectric member and so enables the leaf spring to force its free end into electrically conducting engagement with the electrically energized spring support. Establishment of that conductive relationship produces a signal that actuates a brush wear indicating circuit that is operatively connected to the leaf spring.
