A ring counter is divided into groups, the first stage of each being operated by external means, whereby failure of the counter at any time is confined to the particular group in which the failure occurs.  The ring counter, which may be used for controlling a railway signalling system, is divided into groups of stages 1-9, 10-19 and so on, the stages being operated one by one under control of pulses alternately on leads S1 S2 and operation of the preceding stage, in known manner. Synchronously with the pulses on leads S1, S2 pulses are applied over lead S to a binary cascade counter of known type. When stages B and D of the binary counter are on, indicating a count of 10, AND gate " &1 " energizes stage 10 in the ring counter and similarly the first stage of each group is energized when the binary counter reaches the appropriate count. The groups of the ring counter may be continuous so that the binary counter is merely an addition to the normal control.

Title: Process for the production of aromatic hydroperoxides, carbinols, ketones and carboxylic acids
IPC: B01J31/18
Filed: 1955-01-28
Abstract: Aromatic hydroperoxides, carbinols, ketones and carboxylic acids are made by subjecting an alkyl-substituted aromatic hydrocarbon or an aromatic compound containing at least one alkyl group and at least one other group directly attached to the nucleus, to the action of molecular oxygen in the presence of a phthalocyanine of iron, cobalt, nickel or copper as catalyst at a temperature of not less than 60 DEG C., the phthalocyanine having previously been purified by dissolution in cold concentrated sulphuric acid, dilution of the solution to an acid content of about 10 per cent by volume, and boiling the precipitate so obtained with a dilute aqueous alkali-metal hydroxide, water and alcohol in succession.  Material which is not dissolved in the sulphuric acid is removed before dilution of the solution.  Small amounts of a hydroperoxide and relatively small amounts of weakly alkaline or amphoteric materials such as alumina and/or magnesia may be added to the reaction mixture.  The reaction may be conducted at atmospheric or elevated pressures.  p-Toluic acid may be oxidized by the process to give terephthalic acid.  In examples: (1) cumene and (2) p-nitrocumene are oxidized in the presence of copper phthalocyanine to give cumene hydroperoxide and p-nitrocumene hydroperoxide respectively, the latter yielding acetone and p-nitrophenol on acid cleavage with perchloric acid; (3) cumene, (4) p-xylene, and (5) n-butyl p-toluate are oxidized in the presence of cobalt phthalocyanine to give respectively a mixture of acetophenone and dimethyl phenyl carbinol, p-toluic acid, and mono-n-butyl terephthalate.

Title: Multi-aperture magnetic core "not" gate
IPC: H03K17/82
Filed: 1965-01-22
Abstract: 1,036,261. Circuits employing magnetic storage devices. AMP Inc. Jan. 22, 1965 [Jan. 28, 1964], No. 2822/65. Heading H3B. A logical NOT circuit comprises a magnetic storage core 10 having a major aperture 12, and outlet and inlet minor apertures, 14, 16, the inner and outer core limbs 1, 2 formed by the inlet aperture being wound with signal and clock pulse windings X, Y, respectively, the major aperture being associated with a clearing winding 24, and the outlet aperture being threaded by a prime winding 26 and by an output winding Z which is wound in figure-of-eight fashion over the two limbs 3, 4 defined by the outlet aperture. Initially the core flux is established about the major aperture by energizing the clearing winding. A binary one signal and a clock pulse each reverse the flux direction in the respective limb 1, 2. If a binary one signal is applied after a clock pulse the direction of the flux about the major aperture becomes wholly reversed and the priming signal which is subsequently applied is without effect. The core flux distributions are such that when the core is partially switched by the clock pulse, fully switched by the binary one pulse and subsequently cleared, equal and opposed voltages are induced in the two halves of the figure-of-eight output winding and the logical NOT operation is therefore obtained. A binary zero is characterized by the absence of a signal in winding X with the result that the core is in the partially switched state established by the clock pulse when priming is about to take place. The core flux distribution produced by the clock pulse is in a reversal of flux direction in limb 2 which causes a partial flux reversal in each of limbs 3 and 4, no effective output being obtained in the output circuit. When priming takes place the flux in limb 3 is restored to its original direction and the flux in limb 4 wholly reversed, again no resultant output being produced in the figure-of-eight output winding. Finally, when the core is cleared the flux in limb 4 is fully reversed and an effective output is induced in one half only of the output winding. The priming and clearing windings may be connected in series.
