Title: Electrical cartridge fuselinks and method of manufacturing such fuselinks.
IPC: H01H69/02
Filed: 1980-12-02
Abstract: A fuse element for an electrical cartridge fuse comprises a fusible wire secured to opposite end zones of an insulating strip by metallic layers sprayed onto the end zones. The insulating strip has a slot therein between the end zones to prevent the fusible, central section of the wire from contacting the strip. The fuse element is disposed in an insulating barrel and the layers are soldered to end caps of the barrel to connect the fusible wire thereto. Fuse elements of this construction are produced by disposing a fusible wire along a continuous strip of insulating material formed at equally spaced intervals with slots and spraying the metallic layers onto the strip between the slots so as to adhere the fusible wire to the strip. Thereafter, the strip is severed at the zones between the slots so as to produce individual fuse elements. This method of manufacture facilitates the production of cartridge fuses utilizing small diameter fusible wires.

Patent ES-8306846-A1 (ES)
Title: Shut-off valve for liquid or gaseous fluids
IPC: F16K31/365
Filed: 1981-06-09
Abstract: A valve housing with a horizontal partition between an inlet port and an outlet port coacts with a hollow plunger which is vertically displaceable above that partition and has a lower end fitting into an aperture thereof traversed in an upward direction by an incoming fluid. The plunger is guided in a surrounding sleeve threadedly connected at its bottom with the valve housing and at its top with a cap having a boss traversed by a stem which is integral with a control handle threaded onto that boss. The lower end of the stem adjoins an elastic membrane which is clamped between the cap and the sleeve and which bounds a fluid space above an end wall of the sleeve this space permanently communicates via channels in the sleeve and external flutes in the plunger with the outlet port of the housing and is further connected through a tubular neck of that end wall with the interior of the plunger and thus with the inlet port when the membrane is lifted off this neck. In such a case the pressure of the incoming fluid, acting upon an internal shoulder of the plunger, raises the latter off the partition to establish a direct flow path between the two ports. When the stem is lowered to let the membrane obstruct the neck of the sleeve wall, the plunger returns by hydraulic pressure to its flow-blocking position.

Title: Serial printer with sentence memory
IPC: B41J5/30
Filed: 1981-10-30
Abstract: The electronic typewriter with a carriage supporting a front wheel, has a sentence memory and display, for word processing. A print pressure table controls hammer duration (using a counter) depending on the character size, for uniform print density. A print pitch table controls print pitch, and ribbon feed (using a counter), according to character width. The front wheel can be exchanged according to character size/pitch, the table outputs being multiplied by coefficients depending on the wheel to reduce memory size. Feedback through an RC circuit is used near the target position in positioning the front wheel, and also the carriage. Carriage position is indicated on one of three scales according to pitch selected. Sheet feed can be controlled (using a counter) from the keyboard, via the sentence memory. A counter can scan the keys, a two bit latch corresponding to an actuated key being set to prevent repeated output of the corresponding count, the latch being then decremented on each scan. The display has a secondary character generator for characters not common to all countries.

Title: Recovery of a cumene/alpha-methylstyrene fraction from a mixture thereof with phenol and water
IPC: C07C67/00
Filed: 1982-06-07
Abstract: A process is disclosed for the recovery of a cumene/alpha-methylstyrene fraction from a mixture thereof with phenol and water. Said mixture is introduced into a fractionation column at conditions to separate an overhead fraction comprising cumene and alpha-methylstyrene and a phenol bottoms fraction. A vapor stream comprising cumene, alpha-methylstyrene and a phenol-water azeotrope is withdrawn from an intermediate level of said column and condensed to form an organic phase and an aqueous phase comprising phenol. The latter is discharged, and the former is recycled to the column. The overhead fraction thus requires substantially less caustic to neutralize the residual phenol container therein.
Patent ES-8304595-A1 (ES)
Title: Stable aqueous film-forming dispersions.
IPC: C09D167/00
Filed: 1982-06-28
Abstract: Preparation of stable aqueous dispersions of particles of film-forming polymer, the particles comprising at least one pre-formed polymer and at least one polymer formed in situ ("multi-polymer particles"). The inadequate stability exhibited by many previously known film-forming systems based on multi-polymer particles, especially in the presence of co-solvents, may be overcome by preparing the particles in the presence of a stabilising compound which is an amphipathic compound with a hydrophilic-lipophilic balance (HLB) value of at least 8 and whose lipophilic portion comprises at least one ethylenic double bond. The dispersions of this invention are useful as the film-forming components of coating compositions.
Patent ES-8405540-A1 (ES)
Title: Circuitry for controlling a CRT beam.
IPC: G09G1/12
Filed: 1983-01-05
Abstract: Beam characteristics, including writing speed, slope, position and intensity, are controlled by circuitry which includes a single digital-to-analog converter (210) sample-and-hold circuitry (250, 260, 270) and a pair of active integrator circuits (280, 290). A microprocessor is adapted to control these circuit components. A data multiplexer (230) selectively applies the DAC output to a preselected sample-and-hold circuit means. The microprocessor is operative to provide digital words to the DAC representative of the differential X and Y values of a line segment to be drawn. The analog representations of these digital words are coupled to the integrators. The outputs of the active integrators provide the deflection signals causing deflection of the CRT beam. The apparatus is particularly adapted to drawing a series of connected line segments, due to the integrator operation. A line segment length may be scaled simply by varying the time interval the analog signals are applied to the integrators, while the writing speed remains constant. The apparatus can also be adapted to display a pseudo-raster scan field.

Patent ES-8600521-A1 (ES)
Title: Dual field of view sensor.
IPC: H04N3/08
Filed: 1984-03-23
Abstract: A dual field of view sensor, particularly adapted for use as a forward-looking infrared night vision detector, includes a single detector (24) for receiving a light signal and developing an output electrical signal therefrom. A rotating polygon scanner (16) having a plurality of reflective facet (14) thereon receives light (12, 34) from two separate optical systems (10, 32) and directs the light onto the facets (14) of the scanner (16) at positions offset by one-half the facet angle such that the light beams alternately strike a facet and the juncture between two facets. The reflected light is then directed through a beam splitter 40 onto the detector in an alternating, interleaved sweeping motion. The beam splitter permits only one at a time of the light (12, 34) from entering the detector. In one embodiment, both optical systems include a steerable dual field of view telescope. In a second embodiment, a transparent display (60) such as an LCD panel, impresses a data image on one light beam (52) and the signals developed from that and another light beam are combined to drive a display. In a third embodiment, the two light beams represent the input to a stereoscopic viewing system, and the separate signals developed therefrom are used to drive a pair of small helmet-mounted displays for individual viewing by the wearer's left and right eyes to provide stereoscopic night vision viewing.
