IPC: H01J1/18
Filed: 1929-09-12
Abstract: 318,933. British Thomson-Houston Co., Ltd., (Assignees of Relyea, W. I.). Sept. 12, 1928, [Convention date]. Vacuum tubes. - A filament 5, Figs. 2 and 3, for a valve or incandescent lamp is maintained in tension by two supports 12 on either side of the filament, a member 14, preferably U - shaped, spanning the supports, and springs 13 held under compression and arranged between the member 14 and the supports, and preferably mounted in recesses in the supports. A twisted, stranded member 15 of molybdenum is wound tightly around the member 14, and ends in a loop 25 supporting the loop of the filament. A helix 16, of tungsten or other refractory metal, wound around the filament or the loop 25, prevents. welding action at the place of contact between the filament and loop. The ends of the filament are secured to leads 4 mounted in a stem 2, on which is fitted a slotted cylindrical cap having a perforated plate 9 carrying the supports 12. A sheet of copper mesh may be interposed between the stem and the cap, and the cap is secured around the stem by clamps 17. A quartz spacer 7 with staggered wires may be mounted between the leads 4. A cylindrical anode, not shown, is carried by rods 22, Fig. 4, fixed to a slotted member 19 which is closed by a perforated plate 20. The anode lead 23 passes through and is secured to the plate.

Title: A process for the production of lubricants
Filed: 1939-10-13
Abstract: 533,933. Lubricants; refining talloel. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). Oct. 13, 1939, No. 27832. [Classes 32 and 91] [A Specification was laid open to inspection under Sect. 91 of the Acts, May 6, 1940] Lubricants for internal combustion engines contain soaps of talloel and polyvalent metals, preferably basic soaps of zinc, magnesium, calcium, or aluminium. Up to 5 per cent. is suitable. Fractions of talloel may be used, the ratio of resinic to fatty acids therein is preferably adjusted to one as by distillation, and the talloel may first be purified, e.g. by treating a solution in gasolene at 25‹C. with 5 per cent. concentrated sulphuric acid, removing the acid tar, mixing in 10 per cent. of adsorbent e.g. Terrana bleaching earth, distilling off the gasolene, heating to 150‹C. while blowing in steam or inert gas, cooling, and filtering. In one example, crude talloel is distilled under reduced pressure with steam until 85 per cent. passes over ; the first 15 per cent. is discarded; the remainder is heated to 200‹C. with 25 per cent. excess of zinc oxide, water being added from time to time. 1-2 per cent. of the basic soap is added to lubricating oil.

Title: Radiation type thermometric device
IPC: G01J5/12
Filed: 1949-10-31
Abstract: 664,029. Radiation pyrometers. WING- FOOT CORPORATION. Oct. 31, 1949 [June 2, 1949], No. 27869/49. Class 40 (iii). [Also in Group XXXV] A radiation thermometer comprises an element receiving heat from the body of which the temperature is being measured, a thermocouple with its junction in contact with the element feeding an indicator and means in series with the thermocouple and the indicator for compensating for errors due to ambient temperature, this means including a resistor in series with the thermocouple and its connector lead and a further pair of thermocouples measuring respectively sound and ambient temperature and developing a correcting signal in the resistor proportional to the temperature difference. As shown, two plates 39, 40 which may be of copper foil and which are blackened on their upper sides and brightplated on their lower are supported on wooden pegs in an insulated block 38. To the underside of each plate is attached the junction of a thermocouple A, B. These thermocouples are of constantan-iron and are connected by leads passing through the insulated block to terminals beneath. The iron connection 65 from thermocouple A passes in an insulated sleeve through the hollow tubular body 8 of the instrument which is fastened to a supporting plate 5 by a flange 3. The constantan connection of the same thermocouple is fastened direct to a screw 69 in the thermocouple housing. The iron connection from thermocouple B also passes direct to this screw, while the constantan connection is connected to the junction of a constantan resistor 70, the other end of which is also attached to screw 69 and forms with iron wire 68 a third thermocouple C. The output to the measuring instrument is by way of iron wire 65 and a constantan connection from the junction of constantan wire 61 and resistor 70. The circuit connections are shown in Fig. 6. Thermocouples A and B both produce an output depending on the temperature being measured. The output of thermocouple C depends on ambient temperature. The output of thermocouples B and C are opposed and the current flow through resistor 70 as a result of a temperature difference of thermocouples B and C develops a voltage which compensates the output of thermocouple A for ambient temperature. In a modification, Fig. 7 (not shown), the two heat-receiving plates are joined at their adjacent edges by a mica strip and suspended by wires at their corners from pegs fastened in the insulating block. The Specification also describes the mounting of the thermometer close to a travelling belt on which film is being cast so as to control the temperature of a heater immediately above the belt.
