Title: Liquid fuel dispensing pump
IPC: B67D7/26
Filed: 1972-04-17
Abstract: 1402911 Petrol pumps DRESSER EUROPE SA 17 April 1973 [17 April 1972] 17742/72 Heading A4T A liquid fuel dispensing pump 1 which blends two base grades of liquid fuel comprises an electric reset motor (46) adapted to reset indicating drums to zero when an actuator 3 is operated upon removal of a nozzle 2 from the pump housing, an interlock shaft 27 for switching on and off a computer controlling the indicating drums, and coupling means 21, 23, 26 operated by the reset motor in order to rotate the interlock shaft to thereby switch on the computer. When the nozzle is inserted into the pump housing the nozzle engages a link 6 which via a plate 8 rotates a reset shaft 9 against the action of a spring 5 to the position shown in Fig. 2. The petrol blend is selected by a knob 43 which, if not correctly set, causes an interlock plate 16 to be moved into such a position that the shaft 9 cannot be rotated to start the pump when the nozzle is withdrawn. In operation, the knob is set to the desired blend and the nozzle removed from the housing thereby allowing the shaft 9 to be rotated by the spring 5. Rotation of the shaft, via a crank (44) Fig. 3 (not shown), operates a switch (45) which energizes a reset motor (46). Rotation of the motor rotates gears (48) 20 thereby resetting the indicator drums to zero. After a half revolution of the gear 20, a switch (51) is operated thereby starting the pump motor. A cam 21, Fig. 4, is mounted on the gear 20 so that during said half revolution a lever 23 is operated rotates a shaft 27 via a crank 26 and pin-and slot device; such rotation of the shaft 27 switches on the computer. The lever is locked in this position by means of a spring-loaded latch 29, 29a. When the nozzle is re-inserted into the housing, the shaft 9 is rotated causing a crank 34, Fig. 4, to contact an arm 29b on the latch 29 thereby releasing the latter so that the lever 23 moves under the action of the spring 28 to rotate the shaft 27.

Abstract: 613,484. Electromagnetic induction heating. ARNOT, A. E. R., and SHAY, Ltd., J. E. July 13, 1946, No. 17776. [Class 39 (iii)] [Also in Group XXXVII] In apparatus for heating irons, kettles and like appliances by electromagnetic induction and comprising means for automatically opening and closing the circuit of an electromagnet 14 when the appliance is laid in place and lifted respectively, the electromagnet is movably mounted on a base 13 by means of four parallel spring-arms 34 so as to move downwardly when an iron 11 or the like is placed on it and return when the iron is lifted. The current to the electromagnet is controlled by a switch (see Group XXXVII) comprising a small horseshoe magnet 15 which is attracted towards the magnetic body 11 of the iron when in position so as to close a pair of switch contacts in series with the electromagnet, and the initial upward movement of the iron and electromagnet together releases the horseshoe magnet 45 and cuts off the current thereby destroying the attraction between iron and electromagnet and facilitating removal of the former. An adjustable thermostat (see Group XXXVII) may also be provided, its setting being controlled by a knob 68 on the brass casing 15 containing the switch mechanism, or, alternatively, temperature control may be provided by a regulating switch having tappings to various points on the electromagnet winding. A small lamp 75 shines through a red window 79 in the casing 15 to indicate when the current is on. In Fig. 7 (not shown) the construction of Figs 1-6 is applied to an electric hot plate for heating a kettle or saucepan, the switch mechanism being located beneath the hot plate in a lateral projection on the base plate. The electromagnet 14 is in the form of a laminated core having three upwardly facing poles (Fig 2, not shown) and an exciting coil 23 wound in the spaces between the central pole and the outer ones. The coil may be of aluminium strip covered with an anodised oxide film coating for insulation, or it may be enamelled or oxide-coated copper wire or strip. The electromagnet may be embedded in a heat-resisting plastic filler to exclude moisture, or a cover may be provided with holes through which the poles project slightly. A.C. noise may be eliminated by letting into the electromagnet poleface shading rings which delay the flux through the shaded portion so that maximum magnetic attraction occurs at different times on different parts of the pole-face.
