<p>1,155,587. Control of motors. PHILIPS GLOEILAMPENFABRIEKEN, N.V. 28 June, 1966 [1 July, 1965], No. 28954/66. Heading H2J. The circuit of a washing machine having a wash motor 2 and a centrifuging motor 3 switched in sequence by contacts B, C actuated by a cam driven by a further motor 1 is arranged as shown so that even if B and C are momentarily open together the cam motor 1 continues to run to complete the change over. Although motors 1 and 3 are in series their impedances are such that only cam motor 1 will run. At change over contacts B open and C close thereby disconnecting 2, short circuiting 1 and fully energizing 3. D is a manually or programme operated switch. The wash motor 2 may be controlled by means not shown to run e.g. for 5 sees., stop for 10 sees., then restart in the same or the opposite direction.</p> |
