Abstract: 998,260. Vibratory mechanism. J. N. WILSON. March 20, 1962 [March 20, 1961], No. 10052/61. Heading F2X. [Also in Division B1 Apparatus for agitating a slurry comprises a series of containers arranged to form a closed group, means connecting them alternately at top and bottom for flow therethrough, and a rotary impeller in each container. As shown, there are four octagonal rubber-lined containers 1 to 4 supported by a platform 5 mounted on springs 6, the containers being vibrated by out-of-balance weights 17 rotating with a shaft 15 journalled in bearings 16 fast with the container structure. There is a rubber-covered rotary impeller 8 in each container, mounted on the rigid framework 10 independently of the containers. The slurry is introduced through a port 20 at the top of cell 1, passes down cell 1, up cell 2, down cell 3, and up cell 4. It is then discharged through port 24 or recirculated in whole (for batch operation) or in part through transfer port 25, control being obtained by regulating the relative heights of ports 24, 25 and/or by valve means. The cells may be of any number and of hexagonal, circular or other cross-section.

Title: Improvements in or relating to electric motor control arrangements
Inventor: FRIEDLANDER ERICH SIEGFRIED
Filed: 1957-03-28
Abstract: 831,820. Control of A.C. motors. GENERAL ELECTRIC CO. Ltd. March 13, 1958 [March 28, 1957], No. 10215/57. Class 38 (3). [Also in Group XXXV] A wound rotor induction motor 1 feeds power back into the A.C. supply by having its secondary circuit 9 connected to a frequency converter 10 comprising two groups of grid-controlled mercury arc rectifiers, the two groups being relatively arranged in opposite sense between the lines 9 and 16. The control grids of the individual rectifiers are supplied from transformers in a control unit 11 which is coupled to a phase-shift device 12. The amount of power returned to the A.C. source, and therefore the torque of the motor, is controlled by a signal applied to lines 13, this control signal being dependent upon speed error, the stator or rotor current or other condition of the motor which is required to be maintained constant. When the motor is running at full speed, the secondary windings are short-circuited by switch 14, so preventing the feed-back of current except during acceleration or deceleration periods. The transition from driving to reversecurrent braking is effected by reversing main contactors 5, 6, changing the tapping on autotransformer 15, and adjusting the grid voltage of the converter to a suitable value. Provision may also be made for direct-current braking.

Title: Catalytic reduction of aromatic mononitro compounds
IPC: C07C213/02
Filed: 1962-03-19
Abstract: Aromatic mononitro ethers are reduced to the corresponding amino compounds by treatment with hydrogen at about 25-125 DEG  C. in the liquid phase in the presence of a catalyst of the platinum group having a surface area of at least about 150 square inch per gram, the reaction mixture being so agitated that the water formed in the reaction remains in the mixture and is finely dispersed therein.  No solvent is added.  The catalyst may comprise platinum, palladium, ruthenium or rhodium on a charcoal or alumina support and may be in pelleted, granular or powder form.  The process may be effected at atmospheric or raised pressure and may be a batch process or a continuous process.  In the latter event the reaction mixture may flow successively through two containers, a supply of catalyst being present in each container or the catalyst being allowed to flow from one container to the other.  Examples are given of the reduction of o- and p-nitroanisole, o- and p-nitrophenetole, 2-nitrodiphenyl ether and 2,5-dimethoxynitrobenzene to the corresponding amino compounds.

Title: Improvements in or relating to analogue to digital conversion systems
IPC: H03M1/12
Filed: 1966-03-11
Abstract: 1,140,074. Analogue to digital converters. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. 11 March, 1966 [12 March, 1965 (2)], No. 10708/66. Heading G4H. In an analogue - to - digital converter system of the type comprising a digital part 10, Fig. 3, for generating a feed-back balance voltage for comparison at 11 with the input voltage the comparator output serving to control the digital part so as to achieve a balance, the feed-back voltage has added to it a small auxiliary voltage and this is compared with the input at 31 and the comparator output is used to control the value in the digital part 10. If the value arrived at is "8" the feed-back voltage 41, Fig. 4, is just less than the input voltage 40. This auxiliary voltage #v when added to the voltage 41 exceeds the input 40. The output from comparator 31 is then effective to cause the value to step down to "7" and the process repeats, the input 40 being still less than the combined signal. When the value is stepped down again to "6" the input exceeds the combined signal. The value is then restored to "7" and this is read out to the output store 32. Instead of using two comparators 11 and 31 a single comparator may be used, switched first to balance the feed-back voltage and then to compare the input with the feed-back voltage increased by the auxiliary voltage. The auxiliary voltage, in another form, is alternating. In the form of Fig. 9 (not shown) the input voltage is applied to a chain of comparators having successively lower reference signals derived from a potentiometer. A logic circuit identifies the comparator with the highest reference voltage exceeded by the input. The auxiliary voltage is added or subtracted from the input voltage when the switch is changed over. The auxiliary voltage may be alternating in this form also. The auxiliary voltage defines an amplitude range and determines the channel to which a signal corresponding to any input signal shall be applied. The apparatus is for analysing the amplitudes of pulses derived from a nuclear detector, a pulse being sent to one of a number of counters according to the amplitude range of the pulse.

When R1 and R2 are aliphatic residues they may be straight or branched chain, e.g. methyl, ethyl, propyl, isopropyl, butyl, hexyl, 2-ethylbutyl, octyl, 2-butyloctyl, lauryl, octadecyl or 2-chlorethyl, or aliphatic radicals containing thiocyano, cyano or ester groups.  Specified aromatic residues are phenyl, 2- or 4-chlorophenyl, 2 : 4-dichlorophenyl, 4-nitrophenyl, 4-methoxy-phenyl, naphthyl and 4-diphenyl.  Other specified residues are benzyl, cyclohexyl and tetrahydrofurfuryl.  The reaction is preferably effected at 70-100 DEG  C. and if desired an inert solvent such as benzene, toluene, dioxane, or hexane may be present.  The reactants are preferably reacted in the ratio of one mol. of thiourea or alkyl thiourea to one mol. of the phosphorus compound.  In examples: (1) thiourea is heated with diethyl phosphite for 17 hours at 80 DEG  C. to yield white crystals which consist of a condensation product of equimolar amounts of the reactants; (2) thiourea is heated with dimethyl phosphite for 15 hours at 70 DEG  C. to yield a crystalline condensation product of equimolar amounts of the reactants; (3) thiourea (10 parts) is heated with chlorophosphoric acid diethyl ester (23 parts) for 15 hours at 80 DEG  C. to yield a colourless resin which on recrystallization from boiling ethyl alcohol yields white crystals.  Other phosphite starting materials specified are dibutyl- and diphenyl phosphite.  The products are stated to be useful as lubricant additives and in the manufacture of agents for combating pests.
