Title: Improvements in or relating to devices for changing the magnetisation of a magnetic circuit
IPC: H03K17/80
Filed: 1961-05-09
Abstract: 917,814. Multi-stable magnetic storage devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 9, 1961 [May 12, 1960], No. 16845/61. Class 40 (9). A magnetic core in which several discrete remanent states are utilized is switched from one state to another by a short-duration pulse applied through a gate PS to a winding W2, the gate being opened to terminate the switching action as soon as a rapid change of flux density is detected. The core may comprise a yoke D of material having a substantially rectangular hysteresis loop, Figs. 2 and 4, which is associated with a magnetically soft core A and enables the inductance of a winding W1 to be varied. When a short-duration pulse is applied by a source PB, the circuit potential is distributed between winding W2 and a series inductance L. As soon as the core magnetisation increases from BO to B<SP>1</SP>0, for example, a rapid flux change commences and the voltage across winding W2 increases. This change is detected by a differentiating circuit CR, and an output is applied over a rectifier G to a monostable trigger MS which closes the gate PS. The core flux then reverts to a new remanent value B1, and the monostable trigger resets after termination of the short-duration pulse from PS. In a modification the output from a further winding W3, Fig. 7, may be used to control the gate. In another modification, Fig. 6, the further winding W4 is wound orthogonally, and is pulsed prior to the energization of winding W2 to establish a cross flux. An output pulse is then produced in W4 as soon as the longitudinal core flux developed by W2 is sufficient to reduce the transverse magnetisation. Fig. 7 also includes an additional magnetically-soft core E having windings W5, W6, this core being provided to neutralize the small output developed in winding W3 during the initial charge of magnetisation from the value BO and before the change of flux becomes pronounced.

[Also in Group II] An automatic device for sorting conical roller bearings comprises a pair of sorting rollers 4 which separate parts whose largest diameters are too small or too large, and a sorting disc 13 which separates those parts which are too long, have an incorrect taper, or are in an upside down position, the bearings falling by gravity from the rollers 4 to the disc 13 and then by a feed tube 26 to a machine tool P. A conveyer 2 carries the bearings to the rollers 4 and those which are separated by the rollers fall into reject containers 7, 12 according to whether their largest diameter is too small or too large respectively. Parts whose largest diameters are correct pass through the end portions 10 of the rollers and on to the disc 13, an opening 9 being provided in the tube 8 to prevent the rollers being jammed by an excess of bearings accumulating in that tube. An automatic clutch operated by spring-loaded balls (not shown) acts to stop the disc 13 if the rate of feeding at P is greater than the rate of working of the machine tool. Bodies other than conical bearings, and different sizes of bearings may be sorted by an exchange of the sorting disc 13 and of the end portions 10 of the rollers.
