Patent GB-1265712-A (GB)
IPC: G11B20/14
Filed: 1969-03-17
Abstract: 1,265,712. Magnetic data storage. LEACH CORP. 17 March, 1969 [21 March, 1968], No. 13812/69. Heading G4C. In a binary data handling system, a continuous signal in which the two bit types are represented by a transition at the bit cell boundary with or without a mid-cell transition respectively, is decoded without utilizing any clock signal into a square wave train in which the two bit types are represented by respective constant levels occurring for substantially a full bit cell duration, clock pulses in synchronism with substantially the mid-cell locations of the bit-representing levels being derived from selected transitions in the continuous signal utilizing gating by the bit-representing levels. In Fig. 1, NRZC data is modulated with a clock to give a transition at each bit cell boundary, and a mid-cell transition for each 1, and after filtering at 27 is recorded as an analogue waveform on magnetic tape 30 (or drum or disc) without saturation. On reading, the waveform is amplified 32, low-pass filtered 33 and then compared with itself one-bit delayed 36, after limiting 35, 37, in EXCL-NOR (i.e. equivalence) gate 55, the output of which is low-pass filtered 40 to remove noise spikes due to phase errors, and limited 41 to provide a data output 13 in NRZC form. Clock signals, having a pulse at each mid-cell position of the data at 13, are produced at 23 from the data at 13 and the output of limiter 37 (delayed by a half-bit at 42 to compensate for the half-bit delay produced by filter 40). Delay 42 produces true and inverse outputs from which capacitors 46, 47 (Fig. 3) produce pulses representing negative and positive transitions in its input respectively. The negative and positive transition pulses are passed by NANDs 126, 125 respectively if not inhibited by the set states of flip-flops 146, 145 respectively, each passed pulse being applied to the clock output 23 via NAND 150. If the data at 13 is 1, NANDs 136, 135 are enabled to pass the pulse from 126 or 125 to set flip-flop 145 or 146 respectively. If the data at 13 is 0, the clock pulse at 23 resets both flip-flops 145, 146 via NAND 155. Both flip-flops are also reset if they are both in the set state together, via NAND 111. Thus the first transition pulse during a data 1 is supplied to the clock output and inhibits the next transition pulse, whereas any transition pulse during a data 0 is supplied to the clock output and no inhibition results.

Abstract: 1289090 High density thoria UNITED STATES ATOMIC ENERGY COMMISSION 13 April 1970 [1 May 1969] 17547/70 Heading C1A Thoria of high density or good solubility is prepared from an aqueous solution of thorium nitrate by continuously mixing the said solution with an ammonium hydroxide solution at a temperature in the range 180- 200 F. and controlling the mixing process so as to maintain the pH at a value which is equivalent to a pH of 5À0-6À5 at room temperature (25 C.). The product of this process is a filterable precipitate which can be further processed to produce different highly compacted forms of thoria. A glassy gel-like thoria is produced by peptizing with a small amount of nitric acid (3-10 ml./16 of TL), heating to a temp. in the range 100-175 F. and drying. A chalky white thoria powder is obtained when the filter cake from precipitation of thoria is washed with a dilute solution of NH 4 OH before drying. By using known compacting methods thoria having an apparent density up to 80% of the theoretical density of thoria can be obtained, the thoria being readily soluble in aqueous acidic media as desired.
