For the purpose of preparing for the ignition operation the first switch 12 is arranged to be in its conductive state in the first instance and assume its non-conductive state when the first component winding 6 carries sufficient current for adequate ignition energy, while the second switch 3 is arranged to be in its conductive state and as the instant of ignition is approached the first switch is again arranged to assume its conductive state and the second switch to assume its non- conductive state, so that, with regard to the primary winding of the ignition coil, only the flow of current in the first component winding 6 has to be interrupted by the first switch 12 at the instant of ignition, while the second component winding 9 has already been de-energized by the non- conductive state of the second switch. An electrical storage member (capacitor 40), is used for changing over the first switch 12 (transistors 14) into its non-conductive state when sufficient current for adequate ignition energy is present in the first component winding. A threshold valve switch 46, which for example operates in the manner of a Schmitt trigger, is provided and the output 47 of the switch 46 is used to control the transistors 49 and 14. As shown a mechanically operated circuit breaker 29 is used to control the ignition system.

Title: Nuclear reactor including a fluidic shut-down system
IPC: G21C7/22
Filed: 1973-10-01
Abstract: 1423188 Fluid regulation ATOMIC ENERGY OF CANADA Ltd 1 Oct 1973 [10 Oct 1972]  45749/73 Heading G3H [Also in Divisions F2 G4-G6] In a nuclear reactor shut-down system, a fluidic vortex valve, Fig. 5 and a fluidic control valve, Fig. 4 are employed to control the entry of a liquid neutron absorber into the reactor core [see Division G4-G6]. The vortex valve comprises three control ports 61,62, 63 by which gas normally enters a vortex chamber 70 tangentially to be discharged through an outlet port 69; and three supply ports 64, 65, 66 which communicate with a common supply chamber 67 connected, in the system, to tubes in the reactor core into which the neutron absorber is admitted to achieve shut-down. During normal operation, the pressure field created in the chamber 70 is such that no flow passes from the tubes through the supply ports and the pressure created at the supply ports maintains the tubes pressurized thereby to exclude the neutron absorber from the tubes. The absence of gas flow into the chamber 70 from any two of the three control ports 61-63 results in the valve being switched to a state in which flow from the tubes through the supply ports 64-66 occurs, thereby depressurizing the tubes with the result that the neutron absorber enters the latter. Gas flow to each control port 61-63 is controlled by a respective control valve in which a monostable fluidic element 84 is combined with an electrical actuator 90. The element 84 comprises a supply port 87, a control port 86 and outlet ports 88, 89. The actuator 90 comprises a coil 91 wound around a nozzle 92 adjacent, whose end remote from the element 84 is a flexible diaphragm 93 carrying a member 94 of magnetic material. In the one state of the valve a conduit 96 connects the control port 86, via the open-eneded nozzle 92, with a low-pressure suction source, and the gas supplied via supply port 87 discharges from element 84 via outlet port 89. When coil 91 is energized, nozzle 92 acts as an electromagnetic core to attract member 94 whereby nozzle 92 becomes closed off by abutment with the diaphragm 93. As a result, the gas supplied to supply port 87 now discharges from outlet port 88.

Abstract: 967,125. Sterilizing liquids. SEPARATOR A.B. Dec. 4, 1962 [Dec. 4, 1961], No. 45773/62. Heading A2D. In the pasteurisation or sterilization of liquids by direct injection of steam into the liquid to raise its temperature to a predetermined value which is maintained for a determined time interval, and thereafter evaporating off the steam condensed in the liquid in a vessel under vacuum simultaneously with the reduction in the temperature of the liquid, if the liquid does not reach the predetermined temperature, it is diverted into a return pipe for renewed steam injection, after condensed steam has been evaporated off in another vessel under vacuum. Referring to the drawing, a liquid such as milk, fruit juice and other nutritive or medical liquid from a container 2 after pre-heating in heat-exchanger sections 7 and 8, is subjected to steam injection in a device 10 and thereafter the condensed steam is evaporated off when normal operating conditions apply, in a vessel 16 held under vacuum by a pump 18; the liquid may then be cooled in a cooler 21, homogenized and bottled. If the thermoresponsive controller 40 detects that the liquid has not reached the pre-determined temperature during the steam injection, the flow is diverted at the 3-way valve 14 to a further vessel 22 maintained at the same vacuum as vessel 16 through a communicating pipe 25; the flow is then returned for re-heating either directly through a line 28 or, after cooling in heat-exchanger section 31, through line 32 or at any point of the liquid path through the sections 7 and 8 of the heat exchanger.
