Title: Improved electrolytic treatment of metals
IPC: C25F3/02
Filed: 1948-09-01
Abstract: 683,462. Electrolytic polishing. CHALIN, C. E. J., CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, and EPELBOIN, I. Sept. 1, 1948 [Jan. 17, 1948; July 13, 1948], Nos. 23096/48 and 23097/48. Class 41. [Also in Group XXXV] In a method for electrolytic polishing of metals in a cell containing an electrolyte in which a current passes between the body to be polished, as anode, and a cathode immersed in the bath, the current amplitude is constantly modified to maintain the resistance between the superficial layer of the anode and the cathode substantially at its maximum throughout the polishing operation. The best polishing occurs when the resistance is substantially at its maximum. The resistance may be measured between the whole anode and the cathode, between the cathode and an auxiliary anode in parallel with the main anode, or between the main or auxiliary anode and an auxiliary cathode having a fixed potential. In the arrangement shown in Fig. 1, a cell 10 contains a cathode 12 and an anode 11 which may be the body to be polished or an auxiliary anode. The electrodes 11, 12 are connected to a source of direct current through a rheostat 13 and are also connected to the horizontal plates of a cathode-ray tube 16. The vertical plates of the tube are connected to the terminals of a variable resistance 19 which is kept constant during the polishing operation. By reading the indications given by the cathode-ray tube it is possible to determine the value of the resistance corresponding to the best polishing. The control of the resistance may then be obtained automatically by means of apparatus shown in Fig. 4. A device 20, which is a detector provided with a filter circuit, controls a relay 21 which in turn controls a rheostat 13. When the resistance registered by the device 20 deviates from the previously-determined optimum value, the relay 21 is actuated and reacts upon the rheostat 13 to restore the resistance to its desired value. In a modification the cathode-ray tube apparatus shown in Fig. 1 may be replaced by a superposed alternating current device comprising a generator, the frequency and current of which are fixed, and a detector measuring the alternating e.m.f. at the terminals of the cell. The resistance 19, Fig. 1, is replaced by a resonant circuit comprising, for example, an inductance coil. Instead of the device 20, Fig. 4, a registering device may be used. with superposed alternating current and the relay 21 and rheostat 13 may be replaced by thyratrons.

Title: An improved railway gravitation shunting yard
IPC: B61L17/02
Filed: 1930-08-01
Abstract: 356,894. Warning signals for railway shunting yards. VEREINIGTE EISENBAHN-SIGNALWERKE GES., Siemensstadt, Berlin. Aug. 1, 1930, No. 23263. Convention date, Aug. 27, 1929. [Class 105.] A lamp signal, operated from the signal-box, is provided for each track of a shunting yard to warn shunters of the ap. proach of a vehicle on that track ; the signal is extinguished by the arrival of the vehicle. Each signal is controlled througl a counting gear r, Fig. 2 ; when the control key t is pressed, the relays of the counter is ener. gized to close the contact z and light the lamp signal l; when the vehicle en. ters its track, it passes over a short track circuit, and the track relay closes a contact ml to energize the relay za of the counter and open the contact z. After one of the keys t has been depressed, all of these keys are locked until the vehicle passes over a short track circuit at the entrance to the yard. If now one or more vehicles are to follow the first on the same track and the key t is pressed again before the first vehicle enters the track, de-energization of the sliding track relay and energization of the counter relay za by this first vehicle will not restore the counting gear to its normal position, and contact z will remain closed, and the lamp alight, until the last vehicle of the series enters the track. Instead of the signals being controlled by interlocked keys, they may be controlled by an accumulator, Fig. 5. This comprises two sets of bars crossing one another, one set being connected to relays q which control the signals while the other bars of the other set are successively connected to a bus-bar by a sliding contact s which is stepped on to the next bar by passage of a .vehicle over the track circuit at the entrance to the yard; the sequence in which the signals are released is determined by plug connections u between crossing bars. If these are already track circuits on the points, these may be used for cancellation of the signals ; in this arrangement the contact m1 of the track relay is connected to the relays Zla, Z2a, Fig. 7, of the counting gears of the two tracks connected by the points, through contacts u +, u -, one of which is closed in each position of the points, so that only the counting gear corresponding to the position of the points is affected. Treadle contacts may be used in place of track circuits. Specifications 304,586 and 313,147, [both in Class 104 (i), Railway and tramway crossings &c.], are referred to.

Filed: 1936-08-28
Abstract: 479,536. Refrigerating. MAIURI, G. Aug. 28, 1936, No. 23635. [Class 29] Absorption machine.-In cooling air and other fluid, refrigerant is evaporated under progressively increasing partial pressure in an inert gas to produce cold along a range of temperature, and the fluid is cooled by contra-flow heat exchange with the evaporating refrigerant. The range of temperature is produced along the evaporator d. The inert gas and the liquid refrigerant are both cooled by counter-flow with the evaporating refrigerant before they enter the evaporator and the total pressure in the latter is arranged to be only slightly greater than the maximum partial pressure of the refrigerant. The partial pressure, and therefore the temperature, of the evaporating refrigerant passes through a wide range as it flows in counter-current with the fluid to be cooled which passes through jacket q. The inert gas is circulated between the evaporator d and the absorber e by a fan h. The boiler a is provided with a heating coil a' and baffles a<4> and a cooling coil a<3> serve to rectifv the vapours produced. In an alternative construction of evaporator the inert gas and liquid refrigerant pass through helical pipes entwined with a pipe conveying the fluid to be cooled. The refrigerant drips from a wick on to the coils and flows down over them in counter flow to the fluid therein. Propane ethane or ethylene are proposed as refrigerant and alcohol as an absorbent.
