Title: Apparatus for preventing damage by explosion and fire due to liquid fuels in containers
IPC: A62C3/06
Filed: 1932-09-02
Abstract: 400,396. Preventing and extinguishing fires. GUT, J., 11, Rue Philippe de Girard, Paris. Sept. 2, 1932, No. 24543. [Class 47 (ii).] A device for preventing damage from fire or explosion due to injury of a receptacle for inflammable liquid comprises means for relieving the pressure in the receptacle and for releasing an extinguishing medium. As shown, a perforated pipe 3 in the fuel tank 1 is surrounded by a strainer 5 and is connected to an external tube 6, the fuel being isolated by a frangible diaphragm 7. Above the diaphragm is a piston 9 on the stem of which a pin 10, carrying a perforated disc 11, is loosely mounted. A container 14 for extinguishing medium is held at the upper end of the tube 6 by a spring 17. The disc 11 normally is held in its lower position by a spring catch 12. If there is risk of fire, increased pressure in the tank 1 breaks the diaphragm 7 and forces the piston 9 up the tube 6. The excess pressure is thereby relieved through perforations 8 and, at the same time, the pin 10 opens the valve 16 of the container 14, allowing the extinguishing medium to escape and blanket the tank.

Title: Circuit arrangement for charging a battery of storage cells
IPC: H02J7/14
Filed: 1974-06-03
Abstract: 1450238 Automatic control of voltage and current SIEMENS AG 3 June 1974 [25 March 1974] 24561/74 Heading G3R [Also in Division H2]  A circuit for charging a battery 2 comprises a voltage increasing circuit 6 and a comparator 13 for controlling the output voltage Uc of the voltage increasing circuit, the comparator receiving at its first input a voltage U* equal to the gassing voltage of the battery and at its second input the charging voltage Uc of the battery. The battery may be in an aircraft provided with a D.C. generator 3 the output voltage Un of which may not be sufficient to charge the battery at its gassing voltage particularly since the gassing voltage varies with temperature. The reference gassing voltage U* supplied by a potentiometer 14 is therefore corrected by a temperature dependent voltage U*z supplied by a thermistor 17 and compared with the charging voltage Ub in the comparator 13. The output of the comparator is supplied to a circuit 12 which controls the mark-space ratio of the output signal of a circuit 11. The circuit 11 controls the switching of a thyristor or transistor 8 in the voltage increasing circuit 6 which includes a choke 7 and a capacitor 10. The voltage Uc across the capacitor exceeds the supply voltage Un by an amount dependent on the mark-space ratio of the output signal from the circuit 11 so that the charging voltage for the battery always equals the gassing voltage at the ambient temperature. A charge current limiting circuit including a thyristor or transistor 23 is also provided, the current flowing through a resistor 21 and a limit value current set by a potentiometer 22 being supplied to a circuit 20 which controls the transistor. If the supply voltage Un should exceed the permissible battery charging voltage, a diode 19 enables a signal to be supplied from the comparator to the circuit 20 to switch off the transistor 23.

Title: Improvements in or relating to optical instruments
Inventor: MAXWELL PETER DOUGLAS SCOTT
Filed: 1956-08-10
Abstract: <PICT:0835422/III/1> The growth of air-borne spores in an optical instrument, which interferes with vision, is prevented by providing one or more narrow passages into the instrument through which all air entering or leaving the instrument due to changes in atmospheric conditions must pass, and coating the surfaces of the passages with radioactive material, the radiation from which destroys any spores carried into the instrument with the air.  A theodolite is described in which a tortuous air passage 24 is formed between relatively rotatable parts 22 and 21 by an annular plate 23 carried by the part 22 and projecting into an annular groove formed by the part 21 and a member 17 attached thereto which carries the horizontal glass circle 16.  The plate 23 is coated with zirconium which has been exposed to a hydrogen-tritium mixture to form zirconium hydride and tritide. The bound tritium emits b -rays which destroy any air-borne spores passing through the gap.  The passage is provided with a restriction 2-3/1000 inch in width by bevelling the inner periphery of the annular plate 23 to prevent ingress of microscopic particles or insects.

In a thermal switch employing an expansible fluid under pressure in a container as the heatsensitive element, rupture of the container is caused to open a safety switch in series with the main switch so as to prevent the continued supply of heating fuel in circumstances in which it was not required. The element-shown comprises a diaphragm 18 adjustable by a screw 14 and acting through a button 20 on a snapacting switch comprising levers 28, 38 and a tension spring 36 to open and close contacts 48, 50. Contacts 60, 66 of a second switch in series therewith are carried by members 58, 64 secured to opposite sides of the diaphragm. Normal movements of the latter do not affect contacts 60, 66 owing to a pin-and-slot connection 68, 70 between members 58, 64, but if the diaphragm collapses, member 58 pivots about the right-hand end of slot 70 and opens contacts 60,66.
