Title: Improvements in or relating to storage circuits

IPC: H03K3/315
Filed: 1963-11-11
Abstract: 1,063,698. Metrix stores. STANDARD TELEPHONES & CABLES Ltd. Nov. 11, 1963, No. 44378/63. Heading G4C. [Also in Division H3] An electrical storage element comprises a tunnel diode biased by current fed via a resistance so as to be capable of assuming one of two stable states, the element being set to one or other of its states by voltages applied to one electrode of the tunnel diode and via conventional diodes or transistors to the other electrode of the tunnel diode. As shown in Fig. 9, the tunnel diode TD can be switched from its low voltage state to its high voltage state by raising the potential at C1A and reducing that at RT1 and reset by reducing the potential at C1A and increasing that at RT1. The diodes may be replaced by complementary transistors (T1, T2) as in Fig. 8 (not shown), or one diode and one transistor may be used (Figs. 6, 7, not shown). Tunnel diode storage matrices.-Fig. 9 shows part of a word organized storage matrix in which writing is effected by pulsing the appropriate row and column writing terminals such as RT1, C1B. The data is read out destructively by pulsing the appropriate column reading terminal such as C1A. If the state of any of the tunnel diodes TD is changed by the reading pulse, a pulse will be induced in a winding (Fig. 5A, not shown) coupled to the appropriate inductive differentiating winding such as L1. In Fig. 11 (not shown), writing is effected by pulsing the two appropriate column and row wires. Non-destructive read out is effected by pulsing the wanted words read column wire such as CCA1 and detecting the current change in the appropriate row wire such as RR1. Reference has been directed by the Comptroller to Specification 940,966.

Title: Method of selecting seismic reflections
IPC: G01V1/28
Filed: 1962-12-03
Abstract: 1,018,904. Seismic prospecting. SOCONY MOBIL OIL CO. Inc. Dec. 3, 1962 [Dec. 29, 1961], No. 45606/62. Heading H4D.  A signal characterized by a readily definable peak and indicative of the time of occurrence, in, a reflection seismogram, of reflections from a unique stratigraphic sequence in the earth is produced by correlating a function representative of the seismogram with a function (other than the former function) representative of the reflectivity characteristic of the unique sequence. In the described embodiment the former function is derived directly from a field seismogram trace A (Fig. 2, not shown) which may be produced by known recording means 20 (Fig. 1, not shown), whilst the latter function comprises a reflectivity function C (Fig. 2) derived from a conventional velocity log B (Fig. 2) which may be produced by known means such as e.g. the logging tool 26 (Fig. 1). The correlation of the two functions is effected by the arrangement shown in Fig. 3 in which the first function derived by " playing back " the field seismogram by means of device 20, is recorded via head 35 on a rotating magnetic record 34 and reproduced by heads 36 ... 41 the angular spacings of which, in terms of the travel time of the seismogram on drum 20a of device 20, correspond with the times t 1  ...t 5 , the latter, as shown at B (Fig. 2), being the relative time occurrences of the reflectivity amplitudes C (Fig. 2) related to the velocity contrasts at the interfaces 12-17 (Fig. 1) and derived from the modified velocity log B (Fig. 2). This modification consists in converting the normal velocity log 27 (Fig. 1) to a form in which velocity is plotted as ordinates versus two-way travel time as abscissa to provide the same time base as that of the seismogram A (Fig. 2). The outputs from the reproducing heads 36 ... 41 are then supplied via polarity reversing switches 48 ... 53 and adjustable gain amplifiers 42 . . . 47, the polarities and gains of which are adj usted in accordance with the polarities and amplitudes of the plots f-a respectively of B or C (Fig. 2), to an adding circuit 66 the output of which is fed to a (e.g. photographic) recorder 68. In operation, a succession of seismograms are played-back by device 20 resulting in the production of a succession of correlograms D 1  . . . D 4  the position of the correlation peaks 21 (see also Fig. 2) in the various traces with respect to timet 0  being indicative of the nature of theselected stratigraphic sequence; e.g. in the present case the progressively earlier arrival times of the peaks 21 indicate that the sequence has an " up-dip " characteristic.

The helices are connected to a H.F. generator 14 to form external electrodes for a discharge in the tube. To fix the impurity the tube may contain sintered glass particles or dehydrated inorganic zeolite. Oxygen or water is introduced through pipe 18 into krypton or xenon flowing through pipe 20 to the U-tube 2. The gas from tube 2 containing O 2 , CO 2  and H 2  is passed over activated alumina 24 to absorb CO 2 , over heated Cu or CuO to oxidize H 2  to form water vapour and to fix excess O 2  and then through a drier 28 to form water vapour.

Abstract: 1320554 Molybdenum oxides; ammonium molybdate; sodium; potassium molybdates AMERICAN METAL CLIMAX Inc 30 Sept 1970 [2 Oct 1969 (2)] 46586/70 Heading C1A Molybdenum oxide as such or in the form of molybdate is prepared by heating and agitating an aqueous slurry of particulate molybdenum disulphide bearing material while it is in contact with an atmosphere containing free oxygen at a partial pressure of at least 50 p.s.i., e.g. 300-600 p.s.i. Molybdate is produced when the slurry is alkaline. The particulate material may have an average particle size less than 200 U.S. mesh. The slurry may be heated to a temperature of at least 80‹ C. and the atmosphere present may either be air or pure oxygen. The slurry may contain up to 40% by weight of the particulate material. The solid product containing molybdenum oxide may be filtered off, washed with ammonium hydroxide to provide a solution of ammonium molybdate, the solution concentrated to provide crystals of ammonium molybdate, and the crystals calcined to provide molybdenum oxide. When molybdate is produced, the aqueous alkali may be sodium, potassium or ammonium hydroxides, the corresponding molybdate solution being formed. The pH of the slurry may be maintained at above 7 to 12. If ammonium hydroxide is used the molybdate solution may be reduced with hydrogen to yield molybdenum dioxide which may be heated in air to yield molybdenum trioxide.
