An electric stove is provided with at least one spillage tray 26 immediately beneath a range housing several heating elements, the tray extends over at least the area of the space below the range over which at least two of the heating elements are located. In one form of cooker, four spirally wound elements 5-8, Fig. 1, are mounted on spacer cap 22 having radiating arms 23 of invented channel section which are mounted over a support framework 13-18. The framework is held in place by adjustable screws and locking rings 19, 19a, 19b or 20, 20a, 20b. Alternatively the spiral may rest on a grooved spider support. A cover plate 9, Fig. 2, apertured to allow egress of the elements is provided. The levels of the element surfaces relative to the plate 9 are adjustable in independent pairs (i.e. rear or front rows) by screw means 19 or 20 and the elements are rotatable about an axis 45. Immediately the heating element is mounted a drip tray 26, having domed protuberances 29 and 30 under the heating elements to allow spillage from the elements to run into copier parts 31, 32, and 33 of the tray. Below the tray is mounted a grill element 34 and a reflector 39 may be interposed between the two to reduce the heating effect of the grill element on the tray.

Abstract: 1399391 Spray carburetters ROBERT BOSCH GmbH 15 Sept 1972 [17 Sept 1971] 42795/72 Addition to 1336606 Heading F1B A fuel injection system for mixturecompressing, spark ignition, internal combustion engines having continuous injection into the inlet manifold as claimed in Claim 1 of Specification 1336606 in which the return force is regulated by a flat-seat valve having a diaphragm serving as a movable valve member, the initial stress of a primary spring in the flat-seat valve loading the movable valve member being variable in dependence upon engine operating characteristics and the initial stress of a secondary spring opposing the primary spring being variable in dependence upon the amount of oxygen present in the exhaust gas of the I.C. engine. The system includes a measuring element 3 which moves in a conical portion 2 of the intake pipe in dependence upon the air-flow and which, through its mounting arm 8, moves the spool 11 of a fuel metering valve 7. The movement of the spool is opposed by fluid pressure in a chamber 34 enclosing the end face 12 of the spool. The fluid is fuel taken through a throttle 35, from the main fuel line 17, which is fed by a pump 15 from a tank 16. The pressure in the line 33 is regulated by a valve 37 which comprises a diaphragm 41 and a fixed valve seat 42, and controls the flow of fluid from the line 36 back to the tank 16. The diaphragm 41 is pressed against the valve seat by a primary spring 43, which also abuts a flange on a cup member 47. The position of the cup is varied by a push-rod 46 which bears on a cam 44 mounted on the spindle 45 of the throttle valve 6, so that the position of the cup is representative of the engine operating conditions. A secondary spring 48 opposes the primary spring and at one end abuts an internal shoulder in an armature 49 which is free to slide on a sleeve 50, inside a solenoid coil 51. An oxygen probe in the exhaust gas stream controls the current flow to the coil 51, so that the solenoid is either energized, resulting in enrichment of the mixture being supplied, or is de-energized.

In an electric timepiece the balance comprises two ring members 1 and 2, Figs. 1 and 2, carrying opposed axially magnetized cylindrical magnets 3, 4 which, as the balance swings, embrace two adjustably mounted coils 13, 14 connected respectively to the input and output of a transistor. Counterweights 5 and 6 are riveted to the rings 1 and 2 respectively. A decoupling disc or winding 18 is located between the coils 13, 14. A ferromagnetic member 10, 11, 12 the central part of which may be axially magnetized, completes the magnetic flux path. In a modification, Fig. 3a, a metal member 25 is located diametrically opposite the coils 13, 14 to provide an eddy current damping effect which compensates for variations in the supply voltage. The member 25 is radially adjustable. Temperature compensation is also effected if the member 25 is made of a material having a negative resistance-temperature coefficient. The eddy current damping member or a shortcircuited winding located between the coils serves to eliminate back-coupling between the coils at large amplitude of balance swing and so provide amplitude stabilisation. A neutralising condenser may be used to eliminate backcoupling. The whole assembly may be located in an evacuated magnetically screened casing. A regulating coil short-circuited by an external variable resistor may be provided.
