Title: Thermally-responsive bimetallic starting switch for motors
IPC: H01H61/00
Filed: 1967-07-05
Abstract: A starting device for a single-phase A.C. motor 3 comprises a bimetal switch 7 in series with the auxiliary winding 5, the switch being kept open by an additional heater consisting of a resistor 13 of high positive temperature coefficient. The switch has one or two strips of bimetal 9, 12 initially heated by the current in the auxiliary winding when the switch opens this current flows through the P.T.C. resistor, rapidly heating it and so reducing the current, the heat keeping the contacts open. In alternative constructions (Figs. 2 and 3, not shown), the P.T.C. resistor is a block of material to which the bimetal strips are directly attached, e.g. by sintering, and in one case there is a single bimetal strip, semicircular at the top, so that when the switch opens this part rapidly cools, thereby increasing the gap.
Patent ES-343178-A1 (ES)
Title: Arrangement for combining subtitle information and video signals at the television transmitter
IPC: H04N5/278
Filed: 1967-07-19
Abstract: The invention relates to an arrangement for producing a composite picture in which a television picture 10, Fig. 1, is blanked over an area 12 to produce a dark background against which there is displayed a text 11 of bright letters, the arrangement being characterized by the use of counters which respond to the text signal to measure the height 15 of the text and so control the picture blanking that the text is properly located within the background with blank areas 13 and 14 above and below the text. In Fig. 2, the picture signal, which appears on lead 30, is blanked in a circuit 27 and has the text signal, which appears on lead 16, added in a mixer 32 The presence of a text signal is detected by a counter 23 which responds to the first (i.e. top) line of text and makes a count of picture lines corresponding to a complete frame less the number of lines (typically two or three) corresponding to area 13. At the completion of the count an output pulse is produced which initiates operation of a second counter 25 which responds to the text signal applied over lead 33 and functions to measure the height of the text. A signal to control blanking stage 27 is produced on lead 26, the signal commencing with the pulse from counter 23, lasting throughout intervals corresponding to areas 13, 15 and persisting for a further interval (four lines) corresponding to area 14. To allow for texts occupying two lines another counter 40 is provided which functions in the same manner as counter 23 to control counter 25 but is arranged to respond to the text signals corresponding to the second line. To this end the text signals are applied to the counters 23 and 40 by way of a change-over switch 21, 38 which is operated after the first line of text by counter 35 which responds to the text signal. Picture drive pulses on lead 34 reset counter 35 and switch 21, 38 at the end of each picture. The text and picture signals are synchronous but the text-signal may be applied to lead 16 at a time during the picture interval such that the first signal to appear does not correspond to the top of the first line of text. This will cause operation of counters 23 and 40 at the incorrect times and produce faulty reproduction of the text. To prevent this the text signals are applied via a gate 17 which is controlled by the picture frequency pulse so that the gate transmits in response to a picture drive pulse only after text signals have appeared on lead 16.

Patent ES-359716-A1 (ES)
Title: Automatic Slack Adjusters
IPC: F16D65/60
Filed: 1968-10-30
Abstract: An automatic slack adjuster of the type having a worm and worm-wheel includes a oneway clutch device 12 surrounding a shaft 5 rigid with the worm 4, the device 12 being rotatable relative to the shaft 5 in one direction of rotation, clutched to the shaft 5 in the other direction and looked against rotation when the brake is applied. The worm 4 and shaft 5 are urged in the direction in which a lever 1 is moved to apply the brakes, i.e. clockwise as seen in Fig. 2, by belleville washers 6. As the lever 1 is rotated to apply the brake, the device 12 which is provided with teeth moves a rack 20 slidable on a member 21 to take up a lostmotion Y which corresponds to the normal brake clearance, the member 21 being spring urged against a stop 23. As the lever is rotated further the reaction on worm 4 is sufficient to overcome the force of the washers 6 so as to clamp the device 12 between the worm 4 and a shoulder 17 on the lever 1. Should there be an excessive brake clearance is when the lost motion Y is taken up the brake is not yet applied, as the lever 1 is rotated further the device 12, not having been, clamped, is rotated relative to the shaft 5 in one direction by its movement relative to the rack 20, which is held stationary with the member 21 by a spring 22, to measure the excessive clearance until the brakes are applied to clamp the device 12. Upon release of the brake the device 12 is rotated in the other direction so as to clutch the shaft 5 to rotate the worm 4 in a direction to cause the worm-wheel 3 to close the brake clearance. The one-way clutching of the device 12 may be provided by faces (13) on the radially inner surface of the device 12 which faces each constitute one of a pair of relatively inclined faces with the outer surface of shaft 5, and a roller (14) situated between each of these pairs of faces, Fig. 1 (not shown). The slack may be adjusted manually by a nut 30.

Patent ES-410293-A1 (ES)
Title: Universal miniature connector for plural conductors
IPC: H01R4/24
Filed: 1972-12-21
Abstract: The connector is a basic-splice unit of three parts: an index strip, a connector module, and a cap. The index strip has alternately peaked and flat indexing teeth which help split the wire pairs. The strip acts as a temporary wire holder when dressing in wires to be joined. The connector module contains a double-ended slotted contact element. The module top is similar in design to the index strip top and performs the same functions. The module has two rails along its length which accommodate an optional bridge-connector block. The connector module snap-mounts to the indexing strip. In this process the slotted beam contact element penetrates the insulation and makes contact to the wire while the connector module bears down on the wire on each side of the contact element to firmly snug it in place. Between each tooth of the index strip, a cantilever beam forces the wire against a snubbing brace of the connector module, deflecting differing amounts depending on the wire gauge.

Patent ES-462365-A1 (ES)
Title: Method and apparatus for the detection of a specific binding protein
IPC: G01N33/78
Filed: 1977-09-14
Abstract: The invention provides a method for detecting and determining one component of the reaction between a specific binding protein, e.g., an antibody, and the corresponding bindable substance, e.g., an antigen, by utilizing the affinity of these components for binding one another, in an automated system utilizing a continuously flowing stream of liquid. The method is carried out by introducing successive mixtures of the sample specimen with a set amount of one component of the reaction in tagged form and another, carrier-bound, component, into the liquid stream so that the individual mixtures remain separate, incubating the mixtures and continuously introducing same into a separating system in which at least a portion of the liquid phase is separated from the solid phase, and measuring the amount of the tagged component in one of the separated phases as a measure of the unknown component to be detected. For instance, an unknown antigen in a serum sample is contacted with a solid carrier bound antibody, the mixture incubated, the antigen now bound to the solid phase antibody, removed from the other mixture components and reacted with an additional marked antibody acting against the antigen, to form a sandwich containing solid-bound antibody/antigen/marked antibody, and then separating the solid phase from the liquid phase containing the remaining free-tagged antibody and determining the tagged antibody in either fraction as a measure of the serum antigen initially present.
