Title: Fluid pressure control valve
IPC: F16K11/10
Filed: 1967-12-15
Abstract: A valve for unloading a compressor 14 supplying fluid pressure to a reservoir 18 via passages 20, 22 and non-return valve 32 has a valve 36 between the inlet passage 20 and an exhaust chamber 60 connected to a piston 26 responsive to the pressure differential between passages 20, 22. The exhaust chamber 60 is connected to atmosphere via aperture 43 in end closure 44 and a slide valve formed by a lip cup 48 on the valve 36 and a sleeve 59 which moves downwardly against spring 68 when the inlet pressure rises due to connection 82. The latter movement positions the lip cup against flange 84 closing communication between the exhaust chamber 60 and atmosphere which previously was via flutes 58 opposite the lip cup. When the outlet pressure rises to overcome spring 56 the exhaust valve 36 opens to allow fluid pressure from the inlet to pass into chamber 60 in which it acts on lip cup 48 to again move it opposite flutes 58 and open the exhaust valve wide and to atmosphere. When the inlet pressure is substantially atmospheric spring 68 returns sleeve 59 to its upper position and when the outlet pressure drops exhaust valve 36 closes.

Patent ES-359228-A1 (ES)
Title: Test circuit for reactor safety control system
IPC: G21C7/36
Filed: 1968-10-16
Abstract: In a nuclear reactor safety control system, a test circuit is provided which eliminates the need to remove the control system from service during test. In the control system the clutches holding the plant control rods are released, so as to shut down the reactor, when the variables monitored, such as primary coolant flow, water level, load and neutron flux vary from acceptable values. The control system test circuit is provided with an independent power supply and a manually actuated test switch. To test a section of the control circuit, it is first rendered inoperative to prevent tripping the reactor and is then tested by the manual operation of switches which effect energization of indicating lights if the circuit is in order. When the circuit sections have been tested separately, they are next tested in conjunction, to check the clutch release circuits, the reactor trip being prevented, and a further set of indicating lights being used.

Title: Improvements in or relating to flexible structural plate pipes and the like
IPC: E01F5/00
Filed: 1970-01-31
Abstract: A curved corrugated plate P, e.g. of metal or rigid plastics material such as superpolyamide, has assembly-apertures 7, 8, 9, 10, 11, 12 on the flank portions of the corrugations, arranged in at least one row adjacent each of longitudinal edges 3, 4 and the circumferential edges 5, 6. The apertures of the opposite edge portions are positioned on the flanks of the corrugations so that when two similar plates are assembled with their corresponding edge portions overlapping to form part of a segmented structural plate pipe or the like, pairs of apertures align coaxially. As shown, plate P in Fig. 1 comprises two rows of apertures adjacent each of the edges 3 and 4. Each pair of aligned apertures receives a fastening element, e.g. a bolt and nut optionally including a washer. Each plate may be provided with one or two corner-notches 17 to obviate having to deform the overlapping corner portions during the axial assembly of annular structures V2, V3 (Fig. 3) to form a pipe. (The circumferential edges of each plate are formed by male and female flanks of the corrugations so that the male flank of one plate fits against the female flank of an axially adjacent plate). The plate may be used as part of segmented structural plate pipes of non-circular cross-sections (Fig. 12, not shown), or non-annular sections.
Patent ES-386979-A1 (ES)
Title: Improvements in and relating to integrated capacitor memories
IPC: H03H11/26
Filed: 1970-12-31
Abstract: An integrated capacitor memory used inter alia for delaying transit times of A.F. and V.F. signals comprises a chain of capacitors between which charge can be transferred via a corresponding chain of transistors in response to control signals applied through their bases, the capacitors being constituted by the collector-base capacitances of the transistors, which are formed in islands on a common substrate. Independent signals can be applied to each transistor (Fig. 1, not shown) to give the maximum delay time per transistor but the number of switching sources can be reduced with only a slight loss of delay time by arranging the transistors in a series of groups (Fig. 6) and applying a common signal to the corresponding transistors in each group, which preferably have a common base region with an N+ underlayer, as in the Fig. 10 structure (not shown), which lacks the final diode D of the Fig. 6 circuit. The circuit operates as described in Specification 1,175,600. In Fig. 10 (not shown) the transistors are of lateral type with the emitter and collector zones formed by diffusion into an epitaxial N-type base layer, which may be contacted at one or several points, on a P-type silicon substrate.

Patent ES-476287-A1 (ES)
Title: Signal transfer system for time division switching centres
IPC: H04Q11/04
Filed: 1978-12-22
Abstract: This relates to line signalling arrangements for use in a time division multiplex (TDM) switching centre in which pulse code modulations (PCM) is used. In a "supervision" phase, line signalling is extracted by an access control unit (ACU) at the centre's input for transmission to the centre's central processors however in a "register" phase line signalling is exchanged on a single bit of the PCM channel through the connecting network between the ACU and a multiregister (MR) used for call control. This handles the whole of the signalling functions for that channel in conjuction with the central unit. The control of the ACU and the MR as far as the temporary implementation of this signal transfer system and its control are concerned is effected by setting up a mutual recognition procedure between ACU and MR by detecting a particular signalling condition.
