Patent ES-258432-A1 (ES)
Title: Process for preparing shaped articles of uranium silicides
IPC: C01B33/06
Filed: 1960-05-28
Abstract: <PICT:0908941/III/1> <PICT:0908941/III/2> Shaped articles of uranium silicide are prepared by heating an intimate mixture of U and Si particles in a mould under vacuum to at least 450 DEG C. but below the fusion temperature, e.g. 625 DEG -675 DEG C. for 1 hr., and setting the coherent porous product by heating under vacuum at a higher temperature, e.g. 1400 DEG -1550 DEG C. to obtain a non-porous product. The second stage heating is preferably carried out, out of the mould and may, as the product is a conductor, be effected by passage of an electric current, or by induction. The U and Si mixture in the proportions for the required silicide are compacted in graphite mould 1 by vibration to apparent densities 5,8, 5,6, 4,4, or 3,7 for U3Si2, Usi, USi2 or USi3 respectively. The mould 1, which tapers from the centre towards each end, and is made up of sections joined by force-fitted collars 3, is placed in stainless steel tube 4. When the pressure in tube 4, which is connected through assembly 5 to a vacuum pump, is 10-5 mm. Hg, it is placed in tubular resistance furnace 9. The silicide rod B is cooled, removed from the mould and placed in silica tube 10, which is connected to vacuum through 11 and mounted on movable carriage 13. Fixed induction coil 27 heats the rod, and relative displacement of the carriage to the coil ensures that the hot zone travels through the rod. Fixed tubular resistance furnaces 26 ensure absence of an excessive temperature gradient in the rod. U3Si is also referred to in the Specification.

Patent ES-291521-A1 (ES)
Title: Circuit arrangement for use in a color television receiver
IPC: H04N9/24
Filed: 1963-09-10
Abstract: In a colour television receiver circuit comprising a cathode-ray tube 7 the screen of which incorporates (a) strips for producing an indexing signal of frequency fi which is applied to a frequency divider 4, and (b) " run-in " strips for producing a signal of frequency fo which is applied to cause the divider to operate in the correct phase, means are provided for establishing a minimum value of beam current during a line scan, so that in the absence of a video signal there is sufficient current to ensure the continuous operation of the frequency divider, and for producing a value of beam current during at least a part of the " run-in " interval which is substantially higher than said minimum value. Valve 11 forms a part of the frequency divider 4 and during the interval when the divider is operating, i.e. during the interval t 1 to t 2 in Fig. 3, it is biased negatively by rectifiers 13, 14 so that a potential change is produced across anode load 16, 17 as shown in curve c. Valve 19 is biased to cut-off by line flyback pulses and produces a potential change in the same load as shown in curve b. The resulting combined signal is as shown in curve a and is applied to cathode 10 of tube 7 which is otherwise biased so that beam cut-off occurs at level 21. The tube beam is accordingly (1) cut-off during the fly-back interval t 2 -t 3 , (2) established at a predetermined minimum during the line interval t 1 -t 1 , and (3) established at a substantially higher value during the " run-in " interval t 3 -t 1 . The magnitude of the higher value is determined by selection of resistors 16 and 20. In a second embodiment, Fig. 6 (not shown), the signal from valves 11 and 19 is applied through an inverter stage to control a gate stage through which the combined monochrome and chrominance signal is applied to the cathode-ray tube grid. The operation is such that the gate is cut-off during the " run-in " interval and a pulse of appropriate amplitude established in the video signal. The cathode-ray tube is blanked at the cathode by a circuit which establishes the desired minimum value of current during the line interval. A third embodiment, Fig. 4 (not shown) is identical with that shown in Fig. 1 of Specification 1,026,128. Specification 975,622 is referred to in connection with details of the frequency divider. Specification 1,026,126 is referred to in connection delay requirements of the circuit. Reference has been directed by the Comptroller to Specifications 926,183 and 954,941.
Patent ES-297999-A1 (ES)
Title: Improvements in and relating to electronic arrangement for the automatic control of rail brakes
IPC: B61K7/12
Filed: 1964-03-25
Abstract: In an arrangement for releasing a retarder in a railway classification yard when the speed of a vehicle being retarded has been reduced to a desired value, the vehicle speed is determined by the time intervals between signals generated by a number of equi-spaced wheel detectors positioned adjacent the retarder track. The wheel detectors C are formed in groups 01, C2 &c., each of which is connected via a gate P1, P2 &c., and amplifier 4 to a bi-stable circuit 3 and a counter 6. The counter, the " return to zero " circuit 7 and decoder 9 act to control the gates P1, P2 &c., so that once the rear wheel of the vehicle enters the retarder only signals generated by this wheel are applied to the bi-stable circuit. This circuit, Fig. 5, opens when switched to one of its stable states a gate P10 which controls the passage of pulses from oscillator 13 and pulse former 14 to a counter 12 and when switched to its other state controls the passage of the pulses to a counter 121 via gate P101. When the number of pulses counted in a switching sequence increases to a predetermined value, which is a function of the required release speed for the vehicle then the decoder, e.g. 31 associated with the counter energized during that sequence emits a signal which via a register 41 is applied to one input of a coincidence circuit 38. If, during the next sequence, the number of pulses counted in the other counter reaches the predetermined number then a signal is applied via register 411 to the second input to the coincidence circuit which then generates an opening signal for the retarder. Ensuring coincidence between the counts in successive switching sequences prevents mis-operation due, e.g. to wheel bounce. Further apparatus described in Specification 1,032,382, is provided which modifies the predetermined number in accordance with the deceleration of the vehicle and the time lag in operation of the retarder to ensure the vehicle leaves the retarder at the required speed.

Title: Hydraulic machine
IPC: F04D29/16
Filed: 1967-02-09
Abstract: A hydraulic turbine or pump in which water is supplied to a running seal when the runner is being driven in the unloaded and empty state is provided with a lip to deflect the water leaving the seal into a discharge duct and away from the principal faces of the runner so as to reduce resistance losses. In the case of a centrifugal pump having a runner 2 mounted on a horizontal or vertical shaft 1 which also carries a turbine and an electrical machine, water is supplied to seals 7, 10 through ducts 14, 16, respectively, when the pump is being driven in the empty state. Water leaving seal 7 is deflected by lips 20, 31 on the runner 2 into discharge ducts 22, 32, respectively, and a similar lip 21 deflects the water leaving seal 10 into a duct 23. Thus the sealing water does not flow to the clearances between the principal faces 18,19 of the runner and the adjacent stator parts 3,4 and resistance losses are reduced. Air is also supplied in the regions of the seals through ducts 26, 27, 34 ducts 26, 27 may lead to the clearances between the runner faces 18, 19 and the stator parts 3.4. All the air and water ducts are provided with control valves. In a modification, Fig. 2 (not shown), the deflecting lips are mounted on the stator and comprise rings (38, 42) of metal, rubber or plastic mounted in annular grooves (37, 41) in the parts 3, 4. The same construction is applicable to a turbine.
