Patent GB-294260-A (GB)
Title: Improvements in and relating to carburetters for internal combustion engines
IPC: F02M13/02
Filed: 1928-07-20
Abstract: 294,260. Seignol, E. July 21, 1927, [Convention date]. Spray carburettors. - In carburetting-apparatus wherein fuel has to be lifted by suction to the atomizing point, means are provided to ensure substantial constancy in the height through which the fuel is lifted, notwithstanding considerable variations of level in the main supply tank. Atomizing devices comprising Venturi tubes 9. 10 for normal and 9<a>, 10<a> for slow speed running are carried in a block mounted on the top of the main fuel tank 2. The throats of the Venturi tubes communicate through chambers 8, 8<a> and tubes 7, 7<a> respectively with the bottom of a chamber 1, a float 4 in which actuates a valve 5 for controlling the communication between the chamber and the main tank. The top of the chamber is open to the atmosphere through a pipe 6. The float maintains the fuel at a constant level N<1> and therefore the lift in the tubes 7, 7a is constant until the level N<1> varies, but even in that event the variations in lift will be relatively small since, by using a large float placed near the bottom of the main tank, the height h of the level N<1> will be small. The rich mixture for slow running is conducted through a tube 13 to a bye-pass 14 having an air inlet 16. The rich mixture for normal running is conducted through a tube 11 to the throat of a Venturi 12 in a secondary carburetting device to which air is admitted through a port 17 controlled by a spring-loaded sector valve 18 to a disc 20 on which suction is transmitted through a conduit 23, 22.

Title: Improvements in thermostatically controlled electric switches
IPC: H01H37/48
Filed: 1924-09-09
Abstract: 239,361. Marks, E. C. R., (Hart Manufacturing Co.). Sept. 9, 1924. Thermostats. - A switch for electric heaters, ovens, &c., in which a heat-responsive device operates the switch through adjustable controlling mechanism, has the switch housed in a rotary cover provided with means for seating or adjusting this control mechanism. As shown in Fig. 2, a pivoted switch arm 12 carries at its free end an insulated contact 26 co-operating with lower or upper fixed contacts 10, 11. The contacts 10, 11 are secured to metal terminal plates 22, 23 on the insulating base 20, current being led to the contact 26 through a blade spring anchored at one end in a slot 28 of a terminal plate 29 and pressing the contact arm 12 upwards with its other end. The arm 12 is pivoted by forming a recess near one end opposite a corresponding recess in the upturned end of a fixed bracket 19. The operation of the switch is produced bv a carbon rod 14 resting in a metal tube 13 which is screwed into the base 21. Against the upper end of the rod the shoulder 35 of an intermediate rod 15 is pressed by the spring 36. The rod 15 is slotted at 33, Fig. 4, a lever 30 passing transversely through the slot. The lever 30 is pivoted at a fixed point 31, its free end bearing on the lever 12 near its pivotal point. An adjusting screw 40 is screwed down into the hollow upper part of the rod 15, its lower end bearing on the lever 30. Thus, when the rod 15 moves down under spring pressure owing to the differential expansion on heating of the carbon rod 14 and metal tube 13 the lever 30 is rotated and so moves over the contact arm 12, the arrangement of levers being such that a switching over action occurs with a comparatively small movement of the rod 15. To set the temperature at which the switch operates the rotatable cover 41 which houses the switch is provided with an adjustable plate 45 carrying a downwardly projecting plate 44 engaging the slot of the adjusting screw 40. The range of operation indicated by graduations on the cover is adjusted by rotation of the screw 40 with the cover removed, the cover being afterwards placed in position with the plate 44 engaging the slot of the screw 40, and after final adjustment, of the position of the plate 44 relative to the cover, this plats is clamped in position by screws 48.

Abstract: 962,898. Semi-conductor pulse circuits. TELETYPE CORPORATION. May 30, 1963 [June 6, 1962], No. 21617/63. Heading H3T. A circuit for momentarily de-energizing an electromagnet comprises a capacitor charged via an inductor and discharged via the electromagnet. Fig. 1 shows a control circuit for a high speed tape perforator. The electromagnet 10 is normally energized by current from source 21, adjustable by resistor 22 and temperaturecompensated by a thermistor 23, so as to deflect the reed 15 upwards. Each time a trigger pulse is received at 26, silicon controlled rectifier 29 becomes conductive, charging capacitor 32 resonantly via inductor 31. After one halfcycle, SCR29 becomes non-conductive and capacitor 32 discharges resonantly via transistor 34 and winding 14, overcoming the energizing current from source 21 and allowing the reed 15 to execute one cycle of oscillation. Zener diode 36 limits the voltage across transistor 34 and, with diode 41 dissipates the energy in 32, 14 after each discharge. Spurious triggering by noise is prevented by the biased diode 28. The inductor 31 and capacitor 32 should resonate at the natural frequency of the reed 15. Specification 889,504 is referred to.
