Patent ES-372986-A1 (ES)
Title: Self-seeking electronic switching network
IPC: H04Q3/52
Filed: 1969-10-29
Abstract: In a self-seeking PNPN diode switching network comprising two or more sections isolated by ordinary diodes, cyclically applied end markings cause the PNPN diodes to turn on and off periodically under the control of RC circuits associated with each column of a matrix until such time as the PNPN diodes in a complete path are simultaneously conductive and the ordinary diode included in this path is forward biased. The latter diodes limit the fan-out current and also the possibility of cross-talk due to their property of isolating sections of the network until only a single path therethrough can fire. The PNPN diodes fire according to the rate effect. In Fig. 1, the application of potential +V 2 to a network inlet 11 and of - V 1 to a network outlet 16 causes a first and last matrix diode, e.g. D1 and D5 to break-down whereupon capacitors C1 and C4 apply positive and negative markings to the second and third stage matrices wherein diodes such as D2 and D4 may break-down. Thereafter with C2 and C3 charged respectively positive and negative, ordinary diode D3 is forwardly biased so that the existence of a through path is signified and a holding current can be supplied. In general the end-markings are not applied simultaneously so that the above sequence of events would not occur on first application of these markings. In Fig. 3, the completion of a path after the third application of end-markings is shown. At tl the potential at inlet point 11 has risen to a value sufficient to fire D1 and thence D2 whereas at the outlet point 16 the end marking does not fire D5 and thence D4 until t3 when D1 and D2 have already turned-off due to current starvation. At this time however capacitors C1 and C4 which discharge 50 times more slowly than they charge and capacitors C2, C3 which discharge 1000 times more slowly than they charge are all charged to some extent so that the next application of end marking pulses the various firing times t5-t7 are much closer together than the initial firing times t1- t4. However simultaneous firing does not occur until the next appearance of an endmarking at t8, it being irrelevant now which endmarking occurs first. Furthermore, by virtue of the construction of the network, the original oscillatory frequencies fpn and fqn, of the first and last stage crosspoints rapidly increase until the diodes are turning on and off without reference to the cyclically applied end-markings. When this occurs a through path will then fire also without reference to the timing of the endmarkings. The final self-oscillating frequency of the crosspoints is governed by how fast the diodes in a single row or column can be turned on and off by the potential oscillations in the two RC circuits on each side thereof.

Title: Air brake antilock control
IPC: B60T8/46
Filed: 1974-05-16
Abstract: An antilock control valve for use with an air brake system on a vehicle which also includes an antilock control system capable of detecting actual or potential locking of the braked wheels and providing a signal to actuate the antilock valve.

Title: Method of detecting a leak in any one of the vacuum interrupters of a high voltage circuit breaker
IPC: H01H33/668
Filed: 1976-01-29
Abstract: Discloses a method of detecting a leak in any one of the vacuum-type circuit interrupters of a high voltage vacuum circuit breaker comprising a plurality of normally series-connected interrupters located within a tank of the circuit breaker containing pressurized gas. Through small openings in the wall of the tank, a first set of conductive rods are inserted to make electrical connection with predetermined terminals of the interrupters. Through other small openings in the tank wall, a second set of conductive rods, insulated from the tank wall, are inserted to make electrical connection with predetermined other terminals of the inrterrupters. These predetermined terminals are such that the interrupters are connected electrically in parallel between the first and second sets of rods. Between said first and second sets of rods a test voltage is applied to the interrupters in parallel that is of sufficient value to produce a high probability of dielectric breakdown within any interrupter stressed by said voltage that has lost its vacuum, thus providing an indication of such a loss of vacuum.

Patent ES-461908-A1 (ES)
Title: Thermocompressor utilizing a free piston coasting between rebound chambers
IPC: F01B11/00
Filed: 1977-08-26
Abstract: A thermocompressor is disclosed as including a free piston which coasts upwardly and downwardly in a bypass region of a cylinder between cold and hot rebound chambers at cold and hot ends of the cylinder located at the top and bottom of the cylinder. A compressible fluid alternately flows downwardly and upwardly between the cold and hot cylinder ends via the cylinder bypass in response to the alternate upward and downward coasting of the piston. This alternate fluid flow, in conjunction with a thermal lag heating chamber, regenerator, and cooling chamber, causes an alternate heating and cooling of the fluid which produces a cyclical fluid pressure variation utilizable for driving a load. Although the regenerator, and generally the cooling chamber, are located in the bypass, the thermal lag heating chamber is located beyond the bypass and communicates separately with the lower or hot end of the cylinder for thermal lag driving of the piston during a hot rebound portion of the cycle. During the upward coasting of the piston, fluid is directed out of the hot end of the bypass in a substantially defined stream which flows through a portion of the volume of the hot cylinder end and thence into the heating chamber via a heating chamber inlet port and inlet conduit, thereby producing the required heating during coasting. The inlet port is positioned within the cylinder and very close to the lower or hot end of the bypass for capturing substantially all of the above-mentioned stream of fluid substantially independently of the choice of fluid. The lower or hot end of the free piston is concavely shaped such that it does not strike or undergo substantial frictional contact with the cylinder end-wall defining the inlet port and inlet conduit even though the lower edge of the piston moves below the port during the hot rebound.

Title: Induction system for an internal combustion engine
IPC: F02B31/00
Filed: 1978-11-22
Abstract: Several embodiments of internal combustion engines having relatively large main induction passages and relatively small auxiliary induction passages for delivering a charge to the chambers of the engine. Valve means control the proportion of flow to the chambers through the respective passages so that the low and medium charge requirements are supplied primarily by the auxiliary induction passage. This causes improved turbulance in the chamber at the time of combustion and promotes smooth running, good fuel economy and reduction in unwanted exhaust gas constituents. In conjunction with one feature of the invention, means are provided for accelerating the rate of valve movement during the transition from mixture supply from the auxiliary to the main induction passages to improve performance. In accordance with another feature of the invention, an arrangement is provided for permitting compact placement of the control valves.

Patent ES-478576-A1 (ES)
Title: Digital pulse generator with end-stop detection and control
IPC: H02M1/084
Filed: 1979-03-13
Abstract: A firing pulse generator for sequential firing of thyristors digitally synthesizes time dependent references associated in succession with the respective thyristors with a hard pulse, and predetermined critical counts on a time dependent reference are identified representing the first and second end-stops defining the permissible fire-angle range. A substitute for the hard pulse is generated when the hard pulse is advanced, and when it is retarded in relation to predetermined limits, e.g. the end-stops. The time dependent reference is generated over a range sufficient to cover the permissible fire-angle range defined by the end-stops. Blocking of an illegal hard pulse is effected independently from the generation of a hard pulse. Pulse suppression is performed independently from the generation of a hard pulse, or of a substitute pulse.
