Title: Method and means for addressing matrix memories
IPC: G11C11/06
Filed: 1964-01-31
Abstract: 1,058,051. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 31, 1964 [Jan. 31, 1963], No. 4246/64. Heading H3B. The magnetic switching matrices SM1, SM2, Fig. 4, for the rows and columns of a magnetic data store SpM are each divided into a plurality of blocks I-IV, the switch cores being threaded by row and column conductors R1, R2 and by a bias conductor 1AL common to all the blocks of a matrix, and the cores in each block being threaded by a respective blocking conductor 1BL1-1BL4, 1BL1<SP>1</SP>- 1BL4<SP>1</SP>. The matrix cores are normally biased beyond saturation from 1AL, and a core in a selected block is switched by simultaneously energizing the row and column conductors, and at the same time either energizing the blocking conductor associated with the block in which the core required is located, or alternatively energizing all the blocking conductors except that associated with the selected block, depending on whether the blocking current opposes or aids the bias. Each switch core has the usual output conductor which is connected to either a row or a column winding of the data store. The switching matrices are shown in more detail in Fig. 5, the blocking current opposing the bias so that it is applied only to the switch matrix block required. To reverse the magnetic state of a single switch core, an address control causes transistors SR1, SR2 to be cut off so that diodes D1, D2 become positively biased in the forward direction. At the same time a selected row and a selected column conductor in the respective groups TR1, TR2 are energized by opening a transistor gate c-f, g-k in each of the groups. The bias current is effective for the whole of the operation and is determined by the potentials 30v. + 12v. - 12v. during the various operational steps, the bias circuit being common to both matrices. The blocking current is applied to the selected block by the address control opening a transistor gate BLTl-BLTn, this current causing the selected switch core to reverse its state. Subsequently the column and row conductors are de-energized in turn by switching on transistors SR1, SR2 so that a - 12 v. potential blocks the diodes D1, D2. The removal of the column and row currents and the cessation of the blocking current causes the core to be restored to its initial state by the bias. Similar control is applied to both matrices.

Filed: 1974-01-30
Abstract: 1482561 Ultrasonic fluid-flow measurement LUCAS ELECTRICAL Ltd 15 Oct 1974 [30 Jan 1974] 04261/74 Heading G1G A fluid-flow measurement device e.g. for use in measuring air-flow in a fuel injection system, consists in measuring the variations produced in ultrasonic vibrations transmitted across the fluid-flow in the outlet passage from a vortex chamber into which the fluid flows at inlets in the periphery thereof. Air enters vortex chamber 21 through inlets 22 and passes in continuous vortex motion out through outlet tube 23 on the periphery of which are mounted TX transducer 24 and RX transducer 25. It is stated that the modulation imparted to the received ultrasonic signal is generally dependent on the rate of fluid-flow. The flow-rate may be monitored on a C.R.T., which is arranged to display phase difference signal between the transmitted and received signal. Examples are given, Figs. 3-6, (not shown) of various waveforms produced by differing flow-rates. The received signal alone may be alternatively displayed, Figs. 7-12, (not shown). In another embodiment the individual peaks and/or troughs in the modulated waveforms may be counted electronically over a given period of time to provide a digital fluid flow-rate read-out. In a further embodiment, Fig. 13, (not shown), a detection circuit is used to determine electronically, the transmitted/received phase relationship, having two output terminals (33, 34) whereby for an in phase condition, one terminal is negative, for 180 degrees out of phase, the other terminal is negative and for, 90 degrees phase shift, the polarities are equal, the frequency of the output being used to measure the fluidflow-rate.

Abstract: 1472970 Purified phosphoric acid RHONEPOULENC INDUSTRIES 31 Jan 1975 [1 Feb 1974] 4336/75 Heading C1A Very pure phosphoric acid solutions are prepared by the-counter-current extraction of wetprocess phosphoric acid solution in the presence of sulphuric acid and water by means of a waterimmiscible organic solvent, contacting the resulting organic phosphoric acid solution with an aqueous solution containing phosphate and calcium ions (prepared from calcium phosphate, phosphoric acid and water such that the Ca<SP>2+</SP> content is from 2-6% by wt. as CaO), in order to precipitate the sulphate ions as suspension in the aqueous solution washing the phosphoric acid in organic solvent with water and separating the organic phase from the aqueous washing phase, and subjecting the organic phase to liquid-liquid contact with an aqueous phase to transfer purified phosphoric acid to the aqueous phase and separating off the organic solvent from the product. The second step is preferably performed continuously within a recycled flow of aqueous phosphate and calcium ion-containing solution. The organic solvent is generally a C 4 -C 8  aliphatic alcohol such as isobutyl alcohol, and it may be collected after the last step, possible purified, before recycling for the extraction step. After the washing step the organic extract may be treated either with water to produce an aqueous solution of phosphoric acid or with a neutralizing compound such as alkali metal or ammoniacal compound, to give a partially neutralized phosphoric acid, e.g. (mono) sodium phosphate.
