Title: Cellulose base wrinkle composition
IPC: B05D5/06
Filed: 1946-02-05
Abstract: A wrinkle-drying coating composition comprises a wrinkling oil and a cellulose derivative.  A wrinkling oil is defined as one which includes conjugated double bonds in its chemical structure. It may be a native oil such as tung oil and oiticica oil, or it may be a modified oil such as dehydrated castor oil (blown or unblown), blown linseed oil, and an alkali isomerized oil prepared from a normally non-drying oil such as peanut or cotton-seed oil. The cellulose derivative may be cellulose acetate of 37-39 per cent acetyl value, cellulose acetate of 43-45 per cent acetyl value, ethyl cellulose, or cellulose nitrate.  Preferably, 10 to 50 parts of cellulose derivative are mixed with each 100 parts of wrinkling oil.  Solvents or diluents, e.g. naphtha, toluene, or xylene, are added to obtain a composition of the desired viscosity for application.  Pigments may also be incorporated in the coating compositions.  The pigment may be added in the form of a paste made with wrinkling oil.  The composition may be applied to paper, fabric, or other flexible base material by spraying, spreading, or rolling.  The resulting coating may be dried at 130 DEG  F. for 30 minutes and then at 180 DEG  F. for 30-60 minutes.

Title: A process for the treatment of lubricating oils
IPC: B01J27/043
Filed: 1960-02-02
Abstract: Petroleum lubricating oil which contains polycyclic aromatics is refined by selectively hydrogenating the polycyclic aromatics at 316 to 427 DEG  C. and 36 to 212 kg./cm.2 absolute (i.e. 500 to 3,000 p.s.i.g.), preferably at 343 to 400 DEG  C. and 85 to 165 kg./cm.2 absolute, in the presence of a hydrogen- and hydrogen sulphide-containing gas and nickel sulphide catalyst in which the atomic ratio Ni:S is 1,3 to 3:1, preferably 1,4 to 1,8:1.  The oil to be treated may be unrefined, partly refined, or a lubricating oil fraction, and is preferably deasphalted or asphalt-free but not dewaxed.  The treating gas contains hydrogen sulphide and hydrogen in a molar ratio of 0,0002 to 0,02, and the uptake of hydrogen by the oil is 17,8 to 53 standard m.3/m.3 of oil at a liquid hourly space velocity of 0,1 to 5, preferably 0,2 to 1, volumes of oil per volume of catalyst.  The treated oil is particularly suitable as a base to which viscosity index improves such as a copolymer of 2-methyl-5 vinyl pyridine with lauryl, stearyl and methyl methacrylates, or a copolymer of N-vinylpyrrolidone and lauryl methacrylate, are to be added.  The nickel sulphide catalyst is most suitably prepared by passing a mixture of the oil to be treated together with a small quantity of carbon disulphide through a pelleted catalyst bed, which comprises by weight 40% nickel in the form of nickel carbonate composited with granulated kieselguhr, and maintained at 375 DEG  C. and 106 kg./cm.2, at a space velocity of 1 vol./hr. Alternatively, the catalyst may be prepared by mixing or impregnating suitable supporting materials, e.g. alumina, silica, thoria, zirconia or titania, with reducible nickel salts, followed by conventional drying and/or pelleting procedures.  If desired, the salts can then be reduced to metallic form before sulphiding. Other methods of preparing the catalyst are by sulphiding nickel with hydrogen sulphide, by reacting finely divided nickel metal with carbon disulphide, and by reducing higher nickel sulphides with hydrogen.

Title: Improvements relating to the reduction of distortion of high-frequency currents, particularly applicable to wireless telephony
IPC: H03G5/06
Filed: 1919-02-18
Abstract: 143,309. Western Electric Co., (Western Electric Co.). Feb. 18, 1919. Attenuation equalizers and similar impedance networks.-In systems in which a high-frequency carrier wave of frequency C is modulated by lowfrequency waves, such as speech waves, of frequency S, the modulated wave is made up of three components C, C+S, and C-S, and as the transmission circuit or aerial, which is tuned to frequency C, is not in tune to the currents of frequency C+S, these currents are transmitted or radiated with reduced intensity, which varies with the value of S, so that speech waves, containing currents of several frequencies S, are considerably distorted, the waves of higher frequency being more attenuated than those of lower frequency. According to the invention, this distortion is compensated for by introducing in the low-frequency wave, at the transmitting or receiving station, a certain amount of distortion in the opposite direcion to that incident to the transmission of the modulated wave. Secret signalling may be effected by intentionally distorting the waves so as to render a signal unintelligible to all receiving- stations not equipped with means for compensating for the distortion. In the transmitting-system for wireless telephony shown in Fig. 2, the microphone circuit I is coupled to the input circuit II of the modulator M through a circuit V tuned to a frequency near or above the upper voice frequencies, so that waves of lower voice frequency are attenuated more than the waves of higher frequency. The voice currents are combined with the high-frequency currents from the generator 3 by the modulator M, the output circuit of which is connected to the aerial, which radiates more efficiently the waves of lower frequency, so that the received waves are substantially free from distortion. In modifications, the tuned circuit V is replaced by a resonance transformer, or by a combination of resistance and inductance. Alternatively, the compensation may be introduced at the receiving-station, as shown in Fig. 5, in which the received distorted waves, amplified by the valve A, are led to a circuit 29, 30 tuned to the carrier frequency and are then rectified by a detector D, the plate cricuit of which is connected to a resonance transformer 25, 26, which is more efficient for waves of the upper speech frequencies, thereby introducing the necessary compensation for distortion.

Title: Fuel injection pump
IPC: F02M59/00
Filed: 1941-03-28
Abstract: 543,561. Fuel injection pumps. EICHELBERG, G. March 28, 1941, No. 4243. Convention date, March 30, 1940. [Class 102 (i)] In a fuel injection pump for internal combustion engines, fuel stored under pressure is injected by providing relief of pressure in the fuel feeding pipe, so as to provide both a preliminary injection and a main injection, by means of a single piston 7 co-operating with an enclosed relief chamber 12 which communicates by a passage 11 and a port 16 with the piston cylinder 15. In the lower dead-centre position shown, complete relief is obtained by the suction pipe 18 and port 17 communicating with the upper part of the cylinder 15, an axial passage 23, a groove 22, and a radial port 24 in the piston, and the port 16. When the piston rises, the groove 22 and a control edge 21 on the piston cut off the chamber 12 and the suction pipe 18, and the pressure in the fuel feeding pipe rises. A radial piston-port 25 then reaches the port 16, and the chamber 12 communicates with the pressure feed pipe, thus lowering the pressure therein, and causing a preliminary injection. After this, the groove 22 reaches the port 17 and the pressure feed pipe is brought into communication with the suction pipe 18, again lowering the pressure therein, and causing the main injection. The groove 22 may be replaced by an inclined groove extending over part only of the periphery of the piston, with a radial port diametrically opposite it, and the port 25 also may be associated with a similarly shaped inclined groove, so that rotation of the piston, by means of a sleeve 13 and a rack 14, controls the amount of fuel injected, the timing of the main and preliminary injections, or the complete elimination of the preliminary injection.
