Title: Improvements in the manufacture and production of lubricating and insulating oils
IPC: C10G32/02
Filed: 1927-10-05
Abstract: 305,553. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 5, 1927. Mineral and tar oils.-Lubricating and insulating oils are obtained from coal, tars, mineral oils, and other carbonaceous materials by extracting or destructively hydrogenating the solid materials or cracking or destructively hydrogenating the liquids, and exposing the liquid or fractions thereof, in the coherent liquid phase, to the action of high-tension and preferably high-frequency electric currents. Preferably the extraction, cracking, or destructive-hydrogenation is so carried out as to produce as much product of the middleoil type as possible. The electric treatment may be conducted in presence of hydrogen or other gas, of catalysts or inert material, and at reduced, raised or ordinary pressure. In an example, brown coal is treated with hydrogen at 450‹ C. and 200 atmospheres. Of the product a fraction boiling up to 300‹ C. is treated for several hours with a current of about 10,000 volts and 500 periods. The resulting viscous products are separated by distilling off the lower-boiling constituents, these latter being again treated.

Abstract: 841,474. Capacitors. HUNT (CAPACITORS) Ltd., A. H. Sept. 14, 1956 [Sept. 15, 1955], No. 26450/55. Class 37. A method of making a wound capacitor similar to the type described in Specificaton 841,473 but wherein the backing strip is metallised and undergoes the demetallising process before application of the dielectric coating. An embodiment is shown in radial section in Fig. 5. in which two composite strips are wound together without removal of the baking strip 31. Metallised layers 32, 33 are first applied on opposite faces and adjacent margins 36, 37 are then demetallised. After applying dielectric layers 34, 35 the strips are wound together with demetallised margins on opposite edges so that the backing strips are in the field-free space between electrodes of like polarity. Fig. 6 shows an embodiment in which a single composite strip is used. The backing strip 38 is first treated as in Fig. 5, and then at least one further metallised layer 43 is applied to each side. By forming demetallised margins 45, 46 on opposite edges of alternate layers, each dielectric layer is sandwiched between electrodes of opposite polarity whilst the backing strip remains in a field-free space. It is stated that the composite strip may be wound so that the backing strip may form part of the dielectric. The invention may be applied to capacitors made by the processes described in Specifications 647,573, 680,843. Specification 841,475 also is referred to. Reference has been directed by the Comptroller to Specification 736,479.

[Also in Group XXXVI] A bridge circuit, Fig. 3, for comparing the phases of two sources GS, GR of alternating or pulse voltage has equal impedances Z2, Z4 in two opposite arms, rectifiers D1, D2 shunted by load resistors 59, 60 in the other opposite arms, and equal impedances Z1, Z3 across the diagonals, the first source GS being associated with the diagonal impedance Z1 and the second source with the arm impedance Z2. Output D.C. voltage representing the phase difference in sign and magnitude is taken between the anodes of the rectifiers D1, D2. The arrangement is such that if either of the sources GS, GR is inoperative no output is obtained. Fig. 2 shows the phase detector arranged for synchronizing the linescan oscillator of a television receiver with the incoming synchronizing pulses. The pulses are separated and inverted by the valve 38 and are applied between the earthed anode of the rectifier D2 and the cathode of rectifier D1, the two cathodes being separated by the impedance Z4 comprising condenser 55 and resistance 56. Pulses 24 derived at 52 from the scanning generator are applied through resistor 53 and condenser 54 to a condenser 51 which is connected between the rectifier anodes. A seriesconnected impedance Z3, connected between the anode of D1 and the cathode of D2, is equal to the internal impedance Z1 of the valve 38 and condenser 49 ; and the impedance of the network Z4 is made equal to that Z2 associated with the source of the pulses 24. If the rectifiers D1, D2 and their load resistors 59, 60 have the same ixnpedance, the bridge is balanced to give zero output when either of the two systems of pulses is applied alone. Specification 667,521 is referred to.

Title: Improvements in or relating to methods of preparing new resinous compositions from cyclopentadiene and liquid coating compositions containing same
Filed: 1947-10-10
Abstract: Resinous compositions useful in paints and varnishes are prepared by heating together cyclopentadiene and tall oil at a temperature above 400 DEG  F. and in the liquid phase. p  Superatmospheric pressure is employed and the reaction may be carried out in sealed pressure vessels or by circulation through a reaction tube.  The cyclopentadiene may be in the form of its dimer or its Diels-Alder polymers (trimer, tetramer or pentamer) which depolymerize at the reaction temperature.  The cyclopentadiene or its Diels-Alder polymers may also be initially heated to 400-500 DEG  F. to form liquid and solid polyene resins which are then reacted with the tall oil.  The products are of lower acid number than the starting materials and may be liquid or solid.  The softer and liquid products may be esterified with polyhydric alcohols, e.g. glycerine, pentaerythritol and ethylene glycol, yielding synthetic drying oils of improved resistance to water, acid and alkali.  The solid products which are of pale colour, may be incorporated directly into drying oils such as raw or bodied linseed oil and are soluble in aromatic and naphtha solvents.

Abstract: 156,569. Miller, W. J. Jan. 5, 1920, [Convention date]. Blowing; delivering molten metal.-Relates to a press and blow machine of the camoperated, rotary-table, turnover parison type. The parison mould I, finishing moulds J and mould bottoms 60 are mounted on a continuously rotating table E. The molten metal flows continuously from an orifice 194, Fig. 23, and is cut off by shears 195 into charges which fall through a funnel 135 into the mould I. Suction is applied to the top of a piston 112, Fig. 1, which carries the plunger 113. This raises the plunger and also draws down the charge into the neck mould. A parison mould cover is then applied and compressed air is admitted to the top of the piston 112. This retracts the plunger 113 and blows the parison. The parison mould I is then opened and the neck mould is swung over by means of rack and pinion gear 93, 92, shown on the right of Fig. 1, so as to deposit the parison in the finishing mould J, where it is blown by a horizontally hinged blowhead. The finishing mould J is then opened and the ware discharged by tilting the bottom 60. The air ports in the stationary plate G are shown in plan in Fig. 20 and developed into a straight line in Fig. 21. As the blowing port in the rotary table E passes below the ports 172, 173, 174, 187, blowing air passes to the particular mould. The amount of air is regulated according to the size of the mould by turning off some of the valves V, Fig. 21.
