Title: Improvements in or relating to Magnetic Fluid Flow Control Valves.
IPC: F16K31/06
Filed: 1968-05-03
Abstract: 1,198,557. Valves. ROBERT BOSCH G.m.b.H. 3 May, 1968 [5 May, 1967], No. 20988/68. Heading F2V. A flow control valve, which can be operated either by means of an electromagnet or by means of a manually operable actuator, comprises an armature 1 which is movable within the electromagnet coil windings and between upper and lower valve seats 12 and 5 respectively, a spring-loaded pin 7 which urges the armature into engagement with the upper seat 12, and a hollow plug 11 which has formed on its under-surface the upper seat 12 and disposed within it an adjustable screw-threaded stop member and a grooved plunger 16 which is urged by a spring 15 into engagement with the stop member, a tapered portion of the plunger being capable of entering seat 12. In the state of the valve shown, flow from an inlet 4 takes place through seat 5 and an axial passage 6. Upon moving the armature downwardly, as by energization of the electromagnet or by depressing plunger 16 until it engages the top end 9 of the armature and so moves it into engagement with seat 5, the inlet is closed and flow can take place to an outlet, constituted by the free end of plug 11, via axial armature grooves 10, seat 12 and interior of plug 11. Should it be desired to retain the inlet closed for long periods, then the stop member is screwed downwardly until the plunger moves the armature into engagement with the lower seat. In an alternative construction (Fig. 3, not shown), prolonged retention of the armature in its lowermost position can be achieved by means of a plunger similar to the one above and a stop member which has a cylindrical outer surface and carries a pin which is movable in a groove formed in the plug, the inner end of the groove having a radially extending portion such that downward movement of the stop member accompanied by a quarter-turn rotational movement places the pin in the radial portion wherein it remains until the stop member is moved similarly but in the reverse direction.

Title: Improvements in or relating to burner devices for liquid fuel
IPC: F23D11/44
Filed: 1955-07-21
Abstract: 807,763. Liquid fuel burners. PHILIPS' GLOEILAMPENFABRIEKEN N.V. July 21, 1955 [July 24, 1954], No. 21152/55. Class 75(1) In a liquid fuel burner in which fuel flows to a plurality of vaporizers 1 each connected to a burner 9 or 10 by way of a valve 16, a nozzle 3 and a mixing tube 6, 7 or 8 one burner 10 serves as an auxiliary burner to heat two or more vaporizers 1 including that of the auxiliary burner. The vaporizers 1 are each provided with one or more ribs 17 which may be of a width such as nearly to adjoin those of adjacent vaporizers. All vaporizers are interchangeable and detachably mounted. Each nozzle 3 is cleared by a pricker 5 attached to the valve spindle 16a. A heat conserving shield 4 is placed over the ribs 17 of the vaporizers. The vaporizers are preheated by igniting fuel in a trough 11. The trough 11 is filled from an inclined channel 12 the bottom of which is provided with a series of indentations so that when the fuel is ignited at the upper end of the channel 12 the flame is propagated by the fuel in the indentations 13 to the trough 11. 'The ends 23, 24 (Fig. 4), of the vaporizer 1 are detachable to facilitate removal of a valve spindle 16a and a spring 15 and subsequent cleaning. The liquid fuel is forced to flow through the helical channel formed between the convolutions of the spring 15 so that a relatively long path formed thereby prevents the heated fuel or gas flowing to the inlet end of the vaporizer 1. The tube 1 and the valve spindle 16a are made from poor heat conductive materials.
