Title: Process for modifying aluminium and alloys consisting mainly or partly of aluminium without any added silicon
IPC: C22C1/02
Filed: 1931-08-24
Abstract: Aluminium and its alloys containing no added silicon are improved or modified by adding to the molten metal or alloy, mixtures consisting of fluorides which alone have no modifying effect, or double fluorides, and one or more alkali metal carbonates.  Fluxes such as alkali chlorides, borates, &c. may be incorporated in the mixtures to reduce their melting temperatures.  For alloys containing aluminium which melt at high temperatures such as aluminium bronzes, steel containing aluminium, or precious metal alloys, the reaction mixtures are used without such fluxes.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter:-applying the modifying process in direct combination with the electrolytic reduction of aluminium and its alloys, the alkali carbonate in this case being added to the fluorides used, for example to electrolytes containing cryolite; combining the process with known modifying processes, for example by adding metallic sodium to the molten metal through a covering of the reaction mixture; subjecting the modified alloys, particularly aluminium copper alloys treated with lithium carbonate, to a heat treatment consisting in annealing at temperatures above 400 DEG  C., quenching and ageing. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to optical projection apparatus or photographic copying apparatus
IPC: G03B27/36
Filed: 1948-09-10
Abstract: 672,776. Optical projection and photographic copying apparatus. KODAK, Ltd. Sept. 10, 1948 [Sept. 10, 1947], No. 23851/48. Classes 97 (i) and 98 (i). In one form of the invention a projection lens and a support for an object are optically aligned with an image receiving member and are connected to rollers screw-threaded on a rotatable rod and in frictional contact with a cone whose apex is directed towards the'image receiving member. In one embodiment of this form of the invention, as shown, the negative holder 11 and lens 12 are supported by brackets 23, 25 in which are journalled rollers 26, 27 screw-threaded on the lead screw 20 and frictionally engaged with a cone 29. A shaft 38 carries a handle 44 and a pin 43, and is axially movable to engage the pin with either of the bevel pinions 36, 37 to drive either the lead screw or cone through pinions 34, 35 respectively. The lead screw moves the holder 11 and lens 12 equally to change the image size, not taking-account of focus. Rotation of the cone moves them in a ratio which, it is shown, if the apex of the cone is located in the surface 13, is such as to bring the image into focus without changing its size. In a modification of the invention a separate lead screw, used for adjustment of the lens, is journalled in the bracket 23 and belt or chain driven from the roller 26. A member journalled in the bracket 25 is screw-threaded on this lead screw and is belt or chain driven from the roller 27. In a further modification the roller 26 is screw threaded on the outside of a sleeve threaded on the main lead screw. The outside of the sleeve has a thread of the same pitch as, but of opposite hand to, the main lead screw. The sleeve is secured to the roller 27. If the pitch of the lead screw, the position of the cone apex and the relative points of contact of the rollers 26, 27 are suitably chosen, rotation of the cone changes the image size and maintains focus automatically. Rotation of the lead screw is used to focus an image initially. By driving the lead screw and cone in a fixed ratio the effective position of the cone apex can be moved.

Title: Improvements in the purification of fuel oil
IPC: C10G33/06
Filed: 1947-08-28
Abstract: High-viscosity fuel oil normally used for burning under boilers is rendered suitable for diesel engines and gas turbines by heating it to a temperature at which any emulsions are broken, treating it in a centrifugal separator provided with means for effecting continuous discharge of water as the heavier component and oil as the lighter component so as to free the oil from the water and a part of the solid impurities not dissolved in the oil which are contained in it, and then treating the oil in a second centrifugal separator which is of the clarifier type, at a temperature lower than that of the first separation, to remove the remaining undissolved solid impurities from the oil.  The feed of boiler fuel oil is preferably kept as constant as possible, for example by pumping the oil to the separator by means of a constant speed pump having a volumetric capacity corresponding with that of the separator.  The decrease of temperature between the separations should be at least 10 DEG  F., and preferably 20 DEG  F. or more.  The first separation may be carried out at about 180 DEG F. and when the treated fuel is intended for use in gas turbines the oil inlet and outlet pipes of the separators should be hermetically connected to the bowl so that the oil does not become aerated. Aeration may be further prevented by the use of a so-called paring disc.  The channels of the bowl of the first separator may be so dimensioned as to offer minimum resistance to the flow of the oil and water and wings or other devices may be provided to prevent the liquid from slipping in the channels, all for the purpose of reducing the displacement of the boundary surface between oil and water caused by variations in the throughput and in the ratio between oil and water in the mixture. Specification 243,666, [Class 91], is referred to.  Reference has been directed by the Comptroller to Specification 616,908.
