Patent GB-302324-A (GB)
Abstract: 302,324. Compagnie Francaise d'Exploitation des ProcÚdÚs Plinatus. (Assignees of Plinatus, W.). Dec. 14, 1927. [Convention date]. Adhesives.-A method of joining wood, metal, glass &c. together or to fabrics, leather, paper &c., consists in the steps of stirring a cellulose ester or esters with an aqueous emulsion of a highboiling solvent or solvents (such as glyceryl benzoate, diethyl phthalate, di- or tri-butyrin), heating the mixture to evaporate the water, pressing and rolling the resultant powdery material into a thin layer, applying the said layer between the surfaces to be joined and effecting cohesion by pressure and increased temperature, allowing the whole to cool under pressure. The cellulose ester is stated to be in the gel condition. In an example, 100 parts of wet dispersed nitro-cellulose i.e. nitrocellulose stirred with water until in a seemingly swollen condition, is treated with an emulsion of 20-60 parts of diethyl phthalate and 50 parts of water. The mixture is heated until the water evaporates and a powdery mass is obtained. Resins, such as shellac, colophony, Kauri, congo, zanzibar, elemi, pontianak, may be added in powder form to the cellulose ester gel, preferably immediately before use. Specifications 246,272 and 249,600, [both in Class 70, Indiarubber &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a dry binding agent or adhesive comprising one or more cellulose esters containing a high-boiling solvent or solvents in fine distribution therein, with or without additional substances such as resins. In an example, 700 grms. of dry collodion wool, 300 grms. of water and 600 grms. of dibutyrin are kneaded in a vacuum kneader, and the water evaporated under vacuum. The granular product may be rolled to a foil. Other examples, in one of which dammar resin is included, are given. This subject-matter does not appear in the Specification as accepted-

Patent GB-1113523-A (GB)
Title: Method for the production of monocyclohexylamine
Filed: 1965-07-19
Abstract: Monocyclohexylamine is prepared by the reductive amination of cyclohexanone by contacting cyclohexanone with a stoichiometric excess of ammonia and hydrogen in an ammonia-hydrogen gas mixture in the presence of a hydrogenation catalyst and dicyclohexylamine, at a temperature below 230 DEG  C. and at a pressure of 1-8 atm.  The preferred hydrogenation catalyst prepared by reducing a nickel catalyst, such as nickel hydrate, nickel oxide or nickel hydroxide, at a temperature below 450 DEG  C., reoxidizing by passing a gas containing free oxygen over the reduced catalyst, and again reducing by passing a gas containing free hydrogen over it at a temperature below 250 DEG  C.  Preferably, the nickel catalyst is reoxidized until the ratio of reduced nickel to total nickel is between 55% and 65% and finally reduced with hydrogen at a temperature below 250 DEG C.  The specially prepared catalyst may be supported on a conventional support and may contain basic substances or promoters such as sodium silicate, calcium oxide, magnesium oxide or zirconium oxide.

IPC: G01M15/04
Filed: 1923-12-08
Abstract: 229,427. Highfield Electrical Co., Ltd., Highfield, F. W., and Taylor, H. E. Dec. 8, 1923. Dynamometers, rotaryabsorption.- A motor generator is coupled to an engine whereby the running-in of the engine may be carried out in two or more stages at different speeds and finally the engine may be run under its own power which is measured electrically, the generator supplying electricity through a supplementary circuit to other motor generators of a similar plant or back to supply mains. The motor generator a is compound wound having a series winding b with regulating resistance d, and a shunt winding c provided with a regulating resistance e. The parts c, e may be combined with a shunt discharging circuit containing a suitable, resistance f to prevent sparking when the supply circuit is broken. In series with the machine are arranged a watt-meter h with a central zero, an overload. relay i, a minimum current relay j, a differential relay k, a switch and a maximum power relay m. The supplementary circuit n and a switch o are also provided. The motor generator may be mounted on a torque cradle. The main switch is first closed and a button pressed to close the switch l. The machine a runs as a motor driving the engine at a slow speed. The power consumed is indicated by the watt-meter h and the relay closes the circuit of a red lamp showing that the machine is operating as a motor. If the current taken is excessive owing to excessive resistance to rotation in the engine the relay i opens the circuit. If the current is normal the engine rotates at a slow speed until when the running becomes easier the current becomes a minimum The relay j then causes a white lamp to show to the attendant that the first stage is completed. The resistance d and series field winding b are cut out causing the motor to be driven at a higher speed. As before, the current falls as the engine becomes easier and the lamp shows again when the minimum current is reached. The switch l is now opened and the switch o closed the resistance d being adjusted and the engine run under its own power to drive the machine a as a dynamo. The timing of the ignition and regulation of the carburettor &c. is attended to, and the switches o, l reversed. The current is now diverted to supply which is indicated by a lamp. The watt-meter indicates the power developed and when a predetermined maximum is reached, the relay m causes another lamp to indicate this state. A number of such systems may be arranged in parallel and so connected that the power generated in one or more may be used for running-in purposes in others.

Title: Improvements in magnetic core storage devices
IPC: G11C11/06
Filed: 1953-11-12
Abstract: 740,952. Non - contact - making relaysÀ BURROUGHS CORPORATION. Nov. 12, 1953 [Nov. 13, 1952], No. 31391/53. Class 40 (4). [Also in Group XIX] A non - destructive readout circuit for a bistable magnetic core which includes input means for applying magnetizing fields of one polarity or the other thereto and an output winding, comprises an interrogating winding and an energy storage device associated therewith to form a ringing circuit, means for supplying to the input means a signatpulse of amplitude and duration sufficient to change the magnetization of the core without producing any significant oscillations in the ringing circuit, and means for applying a pulse through the interrogating winding of such amplitude and duration as to change the magnetization in the core if it is in a certain one of its two states and create oscillations in the ringing circuit which supply switching energy to the core when the interrogation pulse is terminated. A positive current pulse applied to a winding 28 can be used to set the core 27 in a state of positive remanence. A similar pulse applied to a winding 29 will set the core in a state of negative remanence. To determine the state of the core without changing it, a much shorter " interrogation pulse " is applied to a winding 30. This pulse tends to drive the core to a state of negative remanence and if it finds that core in the positive state the high impedance met with in driving the core causes a high voltage to be developed across the winding 30 and a capacitor 37 to be charged up to this voltage. As the state of the core is changed an output pulse is developed across a winding 31. After the core has reached negative saturation the winding 30 presents only a low impedance through which the capacitor 37 discharges with a ringing effect which causes it to charge up again in the opposite sense, and when, subsequently current flows in the reverse direction there is just sufficient energy stored in the charged capacitor to drive the core back to its initial (positive) state of remanence. If an interrogation pulse finds the core in the negative state of remanence the low impedance presented by the winding 30 prevents any build-up of charge on the capacitor 37 and the core is left in its initial (negative) state. In this case, since the state of the core is not changed during the interrogation pulse, there will be no significant output pulse on the winding 31. Other embodiments are described in which (i) the capacitor is connected across an additional winding on the core, and (ii) an inductor is employed instead of the capacitor.
