Title: Improvements in magnetic core storage devices
Inventor: BEUREL JEAN
IPC: G11C11/20

Abstract: 1,066,380. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 14, 1963], No. 32649/64. Heading H3B. In a data storage device in which read-out is performed by applying an interrogation signal comprising an alternating part to the magnetic storage elements of the device so as to develop an alternating output signal representing a binary digit by its phase relationship to a phase reference, the output is obtained in true or complement form by selectively changing the phase relationship of the interrogation signal to the phase reference. Oscillations from a parametric cell 1 of phase O or # with respect to a reference phase are superposed on a D.C. in a mixer 10 and applied on wire 14 to a selected column winding 16 of matrix 12 so as to produce an output oscillation of phase O or # if a " 1 " is stored in core 15 or no oscillation if an " 0 " is stored on read wires 17. The latter are each connected to a parametric cell 20 also connected to a reading wire 19 of auxiliary core 18, the arrangement forming a majority circuit favouring the read wire 17 signal. In order to read out the true value of the bits stored in cores 15 the inputs to cell 1 at 3, 4, 5 are such that the output oscillation is of phase O with respect to the reference oscillation and since the core 18 is threaded by wire 19 in the opposite direction to cores 15 the output oscillation of cell 20 will have a phase # in the case of reading an " 0 " from core 15 and an oscillation of phase O in the case of reading a " 1 " from 15. In order to read out the complement value the inputs 3, 4, 5 are such that the interrogation signal has phase # with respect to the reference phase and in this case a core in state " 1 " results in an output from cell 20 of phase # and a core in state " 0 " results in an output of phase O. Writing-in of information is as described in Specification 1,038,299 and the arrangement may also be used in a two-core per bit arrangement as described in Specification 1,061,485

Abstract: 1447138 Flocked rubber sheets YALECO INDUSTRIES INC 26 July 1974 [27 July 1973] 33044/74 Heading B2E [Also in Division D1] A material is formed from a flexible non- porous sheet of natural or synthetic rubber having uniformly distributed throughout its body and over at least one surface thereof, natural or synthetic flock fibres, the total amount of fibres being from 0.5 to 10% by wt. of the material. Preferably the material is formed by blending the rubber and flock fibres, calendering the blend to form the sheet, and distributing the flock fibres over at least one surface of the sheet which is at an elevated temperature to adhere the fibres. In a preferred process, the blend 11 is is fed between the nips of rollers 12 to form two plies 13, 14 which are laminated by roll 15 to form the sheet 16. Rolls 17 control the temperature of the sheet before it is uniformly coated with flock fibres supplied to respective bins 19, 22 enclosing rotating rolls 18, 21 having brushes. Scrapers 23 remove excess fibres which may be recycled to the bins 19, 22. The calendering rolls 12 and temperature control rolls 17 may in addition stretch or otherwise change the dimensions of the sheet. Also the flock fibre coating stations may use an electrostatic device. Once the sheet is coated it may be passed through an oven to cure the rubber, or may be bulk cured. Suitable natural rubbers are listed and examples of synthetic rubbers are olefin, butyl, chloroprene, neoprene, isoprene and nitrile rubbers, S.B.R., polybutadiene, diene modified ethylene-propylene copolymer, and acrylate rubber. Mixtures of rubbers may be used. The rubber may contain conventional curing agents and fillers such as carbon black, clay, TiO 2  or SiO 2 . The fibres may be natural, e.g. cotton, wool or silk, or synthetic, e.g. nylon, rayon, polyester, cellulose acetate, polyacrylic, or modacrylic, polyolefinic, or a combination of any of the above.
