Title: Improvements in or relating to automatic signalling devices
IPC: H04L15/22
Filed: 1929-05-17
Abstract: 312,090. Chauveau, L. L. E. May 19, 1928, [Convention date]. Addition to 303,839. Morse code signal transmitting arrangements.- In the signalling system described in the Parent Specification wherein Morse code signals are selectively transmitted under 'the control of a code drum and a selector, comprising two series of bars disposed at right angles and carrying adjustable contacts which facilitate selection of any desired signal, arrangements are provided whereby the apparatus is stopped after the transmission of a signal and the transmission of an additional signal is effected. As shown, the distributor BA which effects the sequential transmission of the signals is provided with an additional contact L17 which effects stoppage of the motor M of the code drum (not shown). The motor M is started to initiate signal transmission by operating a switch I' into engagement with a contact MA to energize winding 1 of locking relay GA over contact C<3> and thereby close the motor circuit over contact G<1>. The code drum and distributor BA are then rotated continuously until when the switch I<1> is reset at the termination of signalling and the distributor engages contact L17, winding 2 of relay GA is energized over lead FN, A to de-energize relay GA and open the motor circuit. The distributor DS is adapted to transmit, if desired, a signal, e.g., twelve dashes of four seconds duration, additional to those described in the Parent Specification. In order to include the distributor DS in the cycle of operations the lead FN, A is removed and the switch I<1> is operated into its starting position to energize a relay DV over a circuit including contact L17 of the distributor BA. The relay DV withdraws a locking member VR from engagement with a cam CA to permit rotation of the distributor under the control of a motor (not shown) and transmission of the signal by means of relay MN. Energization of relay DV opens the circuit of relay GA at contact C<3> to prevent operation of motor M. At the end of signal transmission contact PC on the cam CA causes operation of locking relay ART which de-energizes relay DV and allows locking-member VR to reengage the cam to stop the distributor. Upon release of relay DV, relay GA operates and the motor M drives the distributor BA to transmit the signals as described in the parent Specification. As soon as the distributor BA leaves contact L17 relay ART is released and at the termination of signalling relay DV is re-energized over contact L17 to again release the distributor DS and repeat the cycle of operations, which is continued so long as switch I<1> engages contact MA. In a modification, the motor M may be utilized for driving the distributor DS, the relay DV being adapted to effect the engagement of the motor either with the distributor DS or the distributor BA and its associated code drum.

Title: Improvements in and relating to aluminium stearate solutions and process of preparing the same
IPC: H01B3/18
Filed: 1941-12-03
Abstract: 557,411. Aluminium soap solutions. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 3, .1941, No. 15557. Convention date, Dec. 4, 1940. [Classes 1 (iii), 91 and 95] [Also in Groups IV, V and XXXVI] A solution comprising an aluminium soap and suitable for use in producing coatings and films, e.g. insulating coatings, or textile sizes, for waterproofing, and for addition to lubricant oils is obtained by the admixture of an aluminium soap, a solvent therefor, ammonia, ammonium stearate or an amine, and a polar solvent. The aluminium soap, e.g. the stearate or palmitate is dissolved in a hydrocarbon solvent, e.g. toluol, benzol, naphtha, petroleum spirit, and ammonia is passed into the solution until it becomes pasty; further ammonia may be introduced while heating the solution. The polar solvent which is added may be a low molecular alcohol, cresylic acid, nitro-benzene or in some cases a plasticizer such as tricresyl phosphate. Alternatively ammonium stearate or an amine may be added to the aluminium stearate solution or in a further method the aluminium soap is mixed with about its own weight of solvent and about one tenth of the calculated amount of concentrated ammonium hydroxide is added to produce aluminium hydroxide and ammonium stearate; further hydrocarbon solvent and the polar solvent are then added. In each case a solution of relatively low viscosity is obtained. When the solution is made with an amine a small proportion of zinc stearate may be added to prevent decomposition. Insulating compositions of high dielectric strength are produced by the addition of the aluminium soap solution to alkyd resin varnishes, e.g. to a linseed oil modified glycerol phthalate resin. Glass fibre insulated wire may be coated with such compositions.

Title: Improvements in the production of oxides of nitrogen from ammonia by catalytic oxidation
IPC: C01B21/26
Filed: 1920-06-15
Abstract: The gas-mixture containing ammonia and oxygen is preheated in part by the gases leaving the contact apparatus and in part by the gasiant heat emitted by the contact mass, the gas-mixture in the latter stage being in contact only with such materials as have no catalytic influence on it, for example, china, fire-clay, magnesia, or the like, and traversing a space in advance of the contact mass preferably not less than 0.5 metres in length, for example of 0.8-1.2 metres.  To prevent premature reaction in the gas-mixture when iron preheaters are used, it is preferred to cool the reaction gases, which are at a temperature of 700 DEG  C., to a temperature not exceeding 400 DEG  C., for example by using them for steam-raising; and, when iron preheaters are employed, it is also advantageous to preheat the gas-mixture preliminarily to a temperature of about 100 DEG  C. in order to obviate injury to the main preheater.
