Abstract: 1470467 Magnetic switch MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 Feb 1975 [4 Feb 1974] 4703/75 Heading H1N [Also in Divisions H5 and H2] Energization of an ultrasonic frequency induction cooking apparatus in the absence of a magnetic cooking vessel 18 is prevented by a pan detector which comprises a magnetic contact unit 36 connected in the energization circuit of the induction heating coil 18 and a magnet 32 which is movable between two positions depending on the presence or absence of the vessel 18 to open and close the contact unit 36 a second permanent magnet 35, opposed to the movable magnet 32 substantially cancelling the weight of the movable magnet 32 and helping to maintain the movable magnet 32 adjacent the vessel bottom despite the tendency of the movable magnet 32 to lose its magnetism due to high frequency heating thereof. The movable magnet 32 is disposed in a sealed metal housing 33 and the contact unit 36 is shielded from the high frequency flux by a magnetic shield 39. The energization circuit for coil 17 comprises a full wave rectifier 12 fed from A.C. mains, a chopper inverter circuit comprising a filter inductor 19 a commutating inductor 20, a filter capacitor 21 a commutating capacitor 22 and an S.C.R. 23 and a feedback diode in inverse parallel relationship, and the pan detector 10. A gating pulse generator 25 is provided to excite coil 17 at an ultrasonic frequency. A gate 26 connected to the pulse generator 25 passes gating pulses to S.C.R. 23 when rendered conductive by a zero point sensing a pulse generating circuit 27 which is connected to a bus-bar 15 to sense the zero voltage point of the full wave rectified voltage of rectifier 12. Once the gate 26 is enabled by the zero point sensing circuit 27 it passes gating pulses to the S.C.R. through circuit 28 provided the contact unit 36 of pan detector 10 is closed. Thus the oil 17 is energized at ultrasonic frequency.

Patent GB-346511-A (GB)
IPC: D06M15/693
Filed: 1930-02-15
Abstract: Threads, yarns, filaments, fibres, fabrics, or garments of material of artificial origin consisting of or containing cellulose or cellulose derivatives such as cellulose acetate or other esters or ethers of cellulose are improved by treatment with rubber latex.  The tendency of fabrics to slip, ladder, or run is diminished by the treatment.  The rubber latex, alone or in colloidal solution or suspension with insoluble white or coloured pigments or with vat dyes to which may be added graphite, may be applied over the whole surface or in parts by the application of a thickened paste by stencilling, printing, &c., the material being, in some cases, previously treated with a swelling agent to facilitate the absorption of the dressing. The rubber latex may be applied together with vulcanizing agents. Examples of insoluble substances for applying with the latex dispersion are zinc oxide, red lead, aluminium hydroxide, barium sulphate, zinc sulphide, calcium phosphate, vermilion, Prussian blue, graphite, Anthrene jade green (colour index No. 1101), and Ponsol Blue 3G. In some cases, and particularly when it is desired to reduce the lustre, the material is treated with an insoluble substance before the latex treatment.  For example, barium sulphate may be deposited on the material by treatment with a soluble sulphate a material which has been impregnated with barium thiocyanate.  A dull black finish may be obtained on fibres of organic derivatives of cellulose by dyeing the material black and then delustring by the method described above.  The material may be dyed before or after the treatment with the rubber latex, and in the case of material to be dyed in the presence of an acid, such dyeing should always precede the latex treatment.  In examples, a fabric of cellulose acetate yarn is treated with a bath containing rubber latex and ammonium thiocyanate; a similar fabric is treated in a bath containing also an aqueous dispersion of graphite; and a satin fabric composed of acetone-soluble cellulose acetate is treated in a bath containing latex and zinc oxide.  Specifications 296,450 and 296,451, [both in Class 140, Waterproof &c. fabrics], are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the application of the treatment to artificial material other than that referred to above, and also to material of animal and vegetable origin.  This subject-matter does not appear in the Specification as accepted.
