Inventor: PREUSS AUGUST-WILHELM
IPC: C10M159/18
Filed: 1989-02-24
Abstract: To avoid an unacceptably high exhaust gas back pressure when operating diesel engines equipped with a particle filter in the exhaust gas stream, an engine lubricating oil is used that has a catalytically active content of an iron compound in an amount of 5 to 20,000 ppm. The use of the additive facilitates the regeneration of the diesel particle filters by burning, especially under operating conditions of the diesel engine that lead only to relatively low exhaust gas temperatures. Iron compounds proposed are ferrocene, ferrocene derivatives, and iron salts of organic acids.

Title: Improvements in or relating to the production of moulded ceramic bodies, ceramic coatings and the like
IPC: C04B33/13
Filed: 1938-01-04
Abstract: In the production of moulded ceramic bodies, layers and coatings by sintering granular and powdered materials, e.g. insulating metallic oxides such as oxides of aluminium, magnesium, beryllium and chromium, an aqueous solution of aluminium formate is used as a binder.  In the case of moulded bodies, the body is formed by thoroughly mixing, e.g. in a grinding-mill, the ground material, preferably aluminium oxide with a solution of aluminium formate, if necessary with additional water, until the desired plasticity is attained, the mixture being then shaped and sintered.  For coatings, preferably more liquid is added to form a paste-like slip into which the article to be coated is dipped or through which, e.g. in the case of a wire, it is drawn.  The coating may also be applied by spraying. The invention is especially intended for the production of insulating bodies, layers and coatings such as are used in the vacuum tube art, e.g. retaining and spacing members for the electrodes, insulating layers between the heating filament and the equipotential layer in indirectly heated cathodes, insulating coatings for wires, &c.

Abstract: 468,628. Valves ; cylinders and pumps. KIPFER, P. Jan. 3, 1936, No. 319. Convention date, Jan. 3, 1935. [Classes 7 (ii) and 7 (vi)] Exhaust ports 4 at the upper end of the cylinder are controlled by the upper edge of a sleeve valve 2, ports 8 in which control, together with the piston, scavenging - air inlet ports 7 and combustion air or mixture inlet ports 10, so as to close the latter after the valve has passed its maximum velocity on its up-stroke. The sleeve valve ports 8 may be divided into two rows as shown. The ports in the cylinder and sleeve valve, both for inlet and exhaust, have the edges towards which the gases flow rounded off, whereas the sides from which the gases flow are made sharp-edged. The Specification as open to inspection under Sect. 91 describes also the following subject-matter : The scavenging and combustion air or mixture may be supplied by compressors driven by the engine or an auxiliary motor, or by a turbo-compressor driven by the exhaust gases, and the mixture may be formed externally of, or within the cylinders. The exhaust gases from cylinders whose exhaust periods overlap little or not at all may be collected in a common spiral housing of a corresponding turbine rotor, or each cylinder has its own sector in the same turbine rotor. In radial-cylinder engines, the exhaust turbine compressor is arranged centrally with respect to the crank shaft, the exhaust gases being led through radial pipes from the cylinders to the corresponding turbine sectors, and the scavenging or combustion air or mixture being introduced directly into the cylinders through short connections from the turbocompressors. In engines with the cylinders in rows, the exhaust turbo-compressors are connected up laterally of the rows, or between them, with their axes in planes at right angles to the crank shaft, and so that the shortest conduits are obtained for all connections. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the oxidation of organic compounds of high molecular weight
Filed: 1929-01-05
Abstract: 327,707. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 5, 1929. Fatty acids; esters.-In the oxidation of hydrocarbons of high molecular weight, such as paraffin wax, by means of gaseous oxidizing agents, the formation of hydroxy-carboxylic acids is largely prevented by making the working conditions gradually milder as the reaction proceeds, for example, as regards the temperature, concentration, pressure, or velocity of the said gaseous agents. Suitable oxidizing agents are the higher oxides of nitrogen, or mixtures containing them, such as is obtained by the oxidation of ammonia, or air may be used. A catalyst such as zinc or aluminium stearate, metal enolate, or metal phosphate may be present if desired. In the examples, a crude paraffin wax is oxidized in three stages by means of a mixture of nitrogen oxides, the temperatures at these successive stages being 110, 90, and 60‹ C. respectively; the product contains less than 10 per cent of hydroxy-carboxylic acids and only 8 per cent of unsaponifiable substance. In a second example for the oxidation of paraffin wax with nitrogen oxides, the reaction is carried out while gradually reducing the velocty of flow of the oxidizing gas, the product in this case containing about 6 per cent hydroxy-carboxylic acids. An example is given of the oxidation of paraffin wax in a cyclic manner, the oxidation being carried out in a series of autoclaves; the first autoclave, which contains the starting material is subjected to the highest temperature and pressure and is fed with nitrogen dioxide. The gas leaving this autoclave contains a proportion of monoxide, and is passed into the second autoclave which is at a slightly lower temperature and pressure, and contains partially oxidized wax from the first autoclave. This is repeated for any number of stages, fresh material being continuously pumped into the first autoclave, and the partially oxidized material being continuously passed to the next lower autoclave, in which the oxidation is continued under slightly milder conditions. Under these conditions, the product contains only 3 per cent of hydroxy-carboxylic acids. Other examples are given of the oxidation of American fuel oil by a mixture of air and nitrogen oxides, and of paraffin wax by means of air; the conditions of oxidation are made gradually milder in the first case by reducing the rate of flow of the oxidizing gas, and in the second by lowering the temperature.

Abstract: 874,997. Latches. WILMOT-BREEDEN Ltd. Jan. 11, 1960 [Jan. 8, 1959], No. 709/59. Class 44. Relates to fastening devices of the type in which two parts between which relative angular and translatory movement occurs during a fastening operation, one of which parts is urged in the angular sense towards and into a relative coupling position and requires the application of a positive turning movement during a releasing operation. According to the invention, the two parts each comprise two separate portions, two of which initially engage during the translatory movement to produce relative angular movement of the parts in the uncoupling direction and the other two portions enter into coupling engagement at the end of the fastening operation. As shown, applied to a vehicle door latch a stationary keeper part 1 is provided with projecting portions 5, 6 and 7, and a bolt part 3 which is rotatable against spring loading about an axis 4 is provided with projecting portions 8 and 9. The arrangement is such that during translatory movement of the parts 1 and 3, the parts move to a safety lock position, Fig. 2 and thereafter to the coupling position shown in Fig. 3. A fixed member 24 incorporating a spring loaded wedge 26 provides restraint, in the coupling position, in a direction transverse to the fastening direction. The latch is operable externally of the door by a push-button (not shown) which acts along a line A ..... A Fig. 5 on a lever 34 which in turn displaces a cam plate 30 carried by the part 3. The cam plate is also movable internally of the door by a lever 44 a portion 47 of which bears on a portion 48 of the cam plate 30. A locking portion 49 on the lever 44 co-operates with the lever 34 when the lever 44 is moved in the opposite direction to that for releasing the latch, to block operation by the push button.
