Patent ES-295375-A1 (ES)
Title: Fluid actuated control system for controlling liquid transferring units
IPC: F15B11/08
Filed: 1964-01-16
Abstract: Apparatus for controlling the operation of a unit for transferring liquid in dependence on the valve of a parameter associated with liquid contained in vessel comprises a jack 1 which controls the transferring apparatus, such as a pump or valve, the fluid pressure supplied to opposite sides of the jack from a supply 2 being controlled by valves 19,21. When the parameter reaches a predetermined valve, a pressure pulse is supplied through a conduit 7 and flows through a normally open valve 14 to open a valve 15 which permits flow from the conduit 2 through branch 18 and normally open valve 17 to cause valve 19 to open and valve 21 to close whereby the piston 1b of jack 1 moves to the right to start transference of liquid. The pulse pressure in conduit 7 also closes a valve 13 and opens a valve 11 the latter valve thereby operates a whistle 12. With the valve 19 open, a branch 16 receives pressure fluid to open a valve 20 in parallel with valve 15 when the pulse pressure ceases, the valve 13 again opens and pressure in pipe 16 moves the valve 14 to connect the conduit 7 to the valve 17. The valve 15 is also closed when the pulse ceases, but flow through conduit 18 continues through valve 20. When a second pulse is received, the fluid flows through valve 14 to actuate valve 17 which opens the conduit 18 downstream of the valve to exhaust thereby closing valve 19 and opening valve 21 to move the piston 1b to the left. Conduit 16 is also open to exhaust through valve 19 thus closing valve 20. When the pulse ceases, valve 13 again opens and the actuating pressure of value 14 is exhausted to move the valve back to the open position and thus valve 17 to open position.

Title: Marking circuit arrangement having means for suppressing marking potential
IPC: H04Q3/52
Filed: 1964-01-25
Abstract: In order to reduce interference in a switching network composed of a number of stages of matrices of bi-stable electronic cross-points each marking voltage employed to establish a conducting channel through the cross-points is disconnected from the cross-points it controls as soon as one of the cross-points becomes conducting. As shown in Fig. 6 a PNPN transistor 1 comprising a cross-point in one switching stage can be switched to its conducting state to provide a speech path by way of a link 5 to a further stage where the path may be continued over a PNPN transistor such as 2. If the cross-point 1 is required in a speech path its emitter is connected to 24 volts and its base is switched from 30 volts, connected over normally conductive transistor 21, to 16 volts by a marking pulse on terminal 16 which cuts off transistor 21. As cross-point 1 switches to its conductive state the appearance of 24 volts on the link 5 triggers a one-pulse generator 27 causing the collector of transistor 21 to rise to 30 volts and thereby discontinue the effect of the marking pulse on terminal 16. Instead of being triggered by the voltage on the link 5 connected to an outlet of the switching stage the one-pulse generator may be triggered by the current pulse which occurs in the inlet to the stage, this arrangement being particularly suited to the last stage of the switching network. The network is of the kind described in Specification 849,873. A check that the network operates correctly when a path is set up across it may be carried out as described in Specification 1,003,773.

Patent ES-360340-A1 (ES)
Title: Improvements in and relating to a Method of Measurement of Electric Charges
IPC: G01T1/142
Filed: 1968-11-16
Abstract: The charge on a capacitor C c is determined with the aid of an electro-meter of capacitance C e from three voltage measurements, for each of which a variable D. C. supply (across AD, Fig. 1, not shown) is adjusted to bring the moving element of the electro-meter into a constant reference position. The three measurements are made: (1) with the capacitor and electrometer in series across the supply, the capacitor initially carrying the charge to be measured (2) as (1) but with the capacitor initially discharged (3) with the electro-meter alone across the supply. The supply voltage required to attain the reference position is measured in each case, enabling the unknown charge to be deduced without calibrating the electro-meter and without knowing the value of C c or of any stray capacitance c in parallel with it. Fig. 2 shows a practical arrangement for measuring the charge on an ionization chamber to determine the radiation dose absorbed by it. The ionization chamber itself (not shown) comprises a cylindrical outer electrode and a central electrode, and is fitted into a brass sleeve 6 on the earthed casing 1 of the apparatus. A pin 13, spring-urged towards the chamber, connects the central electrode to the quartz fibre 8 of the electro-meter. The outer shell 9 of the electro-meter is insulated from the casing 1 and connectible via push-button switch 23 to the variable voltage supply. Plunger 35 enables pin 13 to be earthed to discharge the electrometer and the ionization chamber. The quartz fibre is illuminated by a lamp 38 (gas tube) and viewed through a microscope 39. For safety an earthed flexible contact 40 is arranged to engage the pin when the ionization chamber is not in place.

Title: Method and apparatus for protecting the core of a nuclear reactor
IPC: G21C9/00
Filed: 1975-08-01
Abstract: A method and apparatus for protecting fuel rods in a nuclear reactor core under conditions of a major break in the coolant inlet piping connected to the reactor inlet nozzle. A multi-venturi protector which includes multiple parallel dislosed venturies is mounted in the inlet nozzle. The characteristics of the venturi protector are such that coolant flow through the protector into the reactor is unimpeded, but reverse flow through the protector is restricted when a break occurs in the inlet piping. The resistance offered to such reverse flow permits reactor coolant and emergency core coolant to remain in contact with the reactor core for a time sufficient to allow the fuel rods to decrease in temperature to a low safe level.
