Title: Nondestructive-readout memory device
IPC: G11C11/15
Filed: 1967-06-15
Abstract: 1,123,658. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 15 June, 1967 [15 July, 1966], No. 27674/67. Heading H3B. [Also in Division H1] A non-destructive-readout memory device comprises a pair of anisotropic magnetic films having parallel easy axes of magnetization, each film being disposed in the flux return path of the other film so that the magnetic coupling between the films provides two stable states for data storage in which the respective easy axis magnetizations of the film are in antiparallel relationships and one film is thicker than the other. In the normal quiescent state of a bit of a word organized memory, Figs. 1, 3, the stray flux of the bottom film F1 is closed through the top, thicker, film F2, while the stray flux of the top film F2 closes partly through the bottom film F1 and partly through a magnetic keeper 22 supported by a bit/sense line 12. The magnetization vectors M1, M2 of the two films extend in anti-parallel directions along the easy axes EA of the two films, the respective directions determining the bit to be stored. In order to read a selected word from the store the appropriate word driver 14 is activated to send a read pulse IR through the corresponding word line 10 which returns through ground plane 16 resulting in the magnetization of the bottom film F1 being rotated into the hard axis direction M1<SP>1</SP>, Fig. 4, aligned with the read field HR. The stray magnetic field of film F1 which is anti-parallel with vector M1<SP>1</SP> is applied to the top film F2 but since this film is much thicker than film F1 the vector M2 is rotated through an angle much less than 90 degrees and has a component parallel M2<SP>11</SP> and transverse M2<SP>1</SP> to the easy axis of the film. The component M2<SP>11</SP> provides a bias field HB in film F1 The rapid rotation of the vector M1 in the lower film F1 induces a signal in sense line 12 connected to amplifier 18. When the read pulse terminates vector M2 rotates into its normal position and bias field HB acts on vector M1<SP>1</SP> in film F1 to restore it to its normal position. In order to write a word of information into the store, word driver 14 or a separate word driver sends a pulse through word line 10 and the bit drivers 20 send a pulse of appropriate polarity through bit lines 12, the latter pulses terminating after the word pulse. The pulses result in the magnetizations M1, M2 of the two films assuming like polarities along the easy axes, Fig. 9, both fluxes being closed through the keeper film 22 M4. Immediately after the films have attained this state a pulse resembling a read pulse is sent through the word line which produces a field similar to HR and places the magnetizations into the positions M1<SP>1</SP> and M2 shown in Fig. 4. When the pulse ends the selfrestoring action of film F2 returns M2 into its original position but biases M1 into an antiparallel direction shown in Fig. 3.

Abstract: 956,529. Dividing dough &c. BREAD RESEARCH INSTITUTE OF AUSTRALIA Ltd. July 19, 1962, No. 27865/62. Heading B5A. A dough or batter cutting machine comprises a dough chamber 7, containing dough which is forced by gas pressure applied above towards an orifice 8 (Fig. 3) and allowed to emerge as reciprocating blades 10 open and close. The orifice diameter is varied by two shutter plates 28 closed or opened by a hand wheel 71 and attached mechanism. The blades 10 open and close by means of shafts 29 and arms 32, the shafts 29 being rocked about their axes by a cam and lever arrangement (Fig. 5, not shown). The cam also actuates a gate 75 which locates each tin 9, on a moving belt, under the orifice 8 to receive a dough piece. The cam is rotated via a clutch device which incorporates a lever 56 for stopping and starting, so that the machine can be stopped only with blades 10 closed. A sensing rod 61 detects electrically when the dough level drops to a certain point and stops the machine. The upper portion 7A of the chamber hinges back for cleaning. The dough may be forced out of orifice 8 by gas pressure applied via a conduit 14 or chamber 7 may have a mechanically or hydraulically operated piston, or weights may be used. Means may be provided to vary the gas pressure, and the blade speed is controllable by a variable speed drive 18.

Filed: 1973-06-12
Abstract: 1415027 Analogue to digital converter TAKEDA RIKEN INDUSTRY CO Ltd 12 June 1973 [13 June 1972] 27952/73 Heading H3H In an anaolgue to digital converter, the analogue input is converted to a coarse digital signal and a flux proportional to this digital signal is set up in a magnetic core in opposition to that due to the input. The magnitude of the remaining flux is cancelled by current in another coil and this current is digitized to provide a fine signal. As shown, the analogue signal is first applied to the A/D converter via switches S1, S2 as shown and the four figure digital output is fed via S4 to the most significant stages of output D. The digital output is also fed to controller C which selects the corresponding top on winding Nx on core M. The combination of source of voltage E, differential amplifier A 2  and resistance R 2  supplies a current proportional to E through winding Nx. Switches S 1  and S 3  are operated and a current proportional to the analogue voltage is generated in winding N 1 . The resulting fluxes in core M are in opposition and the remaining flux is sensed using winding Nd. The sensing apparatus compriss oscillator 0 of frequency f, transformer H with centre top secondary earthed, winding Nd, Bond pass filter F (passing 2f), f blocking filter F 2  and demodulator Q. The output of Q is a D.C. voltage proportional to flux. This controls the current in winding Nc to reduce the core flux to zero and the voltage drop across resistor R 3 , which is proportional to the current in Nc is digitized in the A/D converter and fed via the right hand side of swtich S 4  to the least significant stages of display D.
