Title: Improvements in or relating to reversing means for internal combustion motors
IPC: F01L13/00
Filed: 1924-06-23
Abstract: 217,925. Bolinders Mekaniska Verkstads Aktiebolag, J. & C. G. June 23, 1923, [Convention date]. Reversing.-In a device in which the earlier injection of fuel is effected by adjustment of the fuel pump 2 or its plunger 3 relatively to the actuating member 5, the pump or plunger being retained in the reversed position until the earlier pump stroke has been effected, the quantity of fuel injected for reversal is the same as a normal injection. As shown, the member 5 reciprocates on a stepped surface 4. An abutment member 6 in the rear end of the pump is connected by a cross-piece 7 and links 11 to a sleeve 12 slidable on the front part of the pump. A boss 13 on the pump plunger is held by a spring 14 in engagement with the end of the sleeve 12. A reversing lever 17, pivoted on the sleeve 12 and connected by links 22 to the member 4, is normally held in the position shown by a spring 20. For reversing, the lever 17 is moved to the left in Fig. 1, and on encountering a fixed stop 25 it moves forward the sleeve 12 and the members 4, 6, a member 18 on the lever 17 engaging beneath a fixed member 19. The pump plunger is prematurely actuated, and at the end of its stroke it strikes the member 6, returning the sleeve 12 and the member 4 to their normal positions.

Title: Copolymers of 3-methyl-1-butene and their preparation
IPC: C08F210/00
Filed: 1958-05-13
Abstract: Copolymers of 3-methyl-1-butene and an unbranched alpha-unsaturated olefin are made by polymerizing a mixture of the butene and olefin in the presence of a catalyst composed of an organometallic compound, or metal hydride selected from <FORM:0895330/IV (a)/1> where R is hydrogen or a monovalent hydrocarbon radical, and R1 and R2 represent hydrogen or a monovalent hydrocarbon radical, or a halogen when no hydrogen is present in the molecule, and one or more halides of the metals titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, or tungsten.  Specified olefins are ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-nonene, 1-decene and 1-dodecene.  The polymerization is generally effected in a hydrocarbon medium such as benzene, toluene, xylene, methylcyclohexane, cyclohexane, hexane, heptane, or kerosene.  The Specification contains an extensive list of catalyst components.  The preferred catalyst components are triisobutyl aluminium, and vanadium or titanium trichloride.  A grinding medium, e.g. glass bead, may be present in the polymerization mix.  Isotactic copolymers may be obtained when less than 7% of the copolymerizable mix is the unbranched olefin monomer.  The catalyst is preferably formed in situ during polymerization.  The copolymers may be used as condenser tapes, and as films and coatings, e.g. in electrical insulation.

Title: Improvements in the production of carbon disulphide
IPC: C01B31/26
Filed: 1947-06-11
Abstract: Carbon disulphide is prepared by reacting hydrocarbons, particularly methane, at a temperature between 350 DEG  and 700 DEG  C. with elemental sulphur in slight excess in the presence of a catalyst consisting of silica gel, fuller's earth, bauxite, activated alumina or clays of the type used to remove colour or gumforming constituents from petroleum oils.  The catalysts may be impregnated with a promotor consisting of metal compounds of the 5th, 6th, 7th and 8th groups of the Periodic Table; in particular activated alumina impregnated with chromium oxide is mentioned.  The hydrocarbon is preferably preheated to reaction temperature and the sulphur to the same or lower temperature; in the latter case the reaction chamber is also heated.  The reaction products are cooled sufficiently to liquefy only the unreacted sulphur, which is recycled, and the carbon disulphide is extracted from the gaseous reaction products by known means.  Specification 265,994, [Class 1 (ii)], is referred to.

As shown, two rows of cars 12, Figs. 1, 2, 3, run on concentric undulating monorails 10, 11, the crests in each rail being arranged opposite the troughs in the other. Each car 12 has a rear wheel 13 concealed within the car body running on the track, and at its forward end is pivoted by a shaft 14 between concentric driving rings 15, 16 or 17, 18. The driving rings run by means of rollers 19 on tracks 20, 21, 22, 23 and the pairs 15, 16 and 17, 18, rigidly connected by the shafts 14 and, if desired, by further stays, are rotated in opposite directions by one or more symmetrically disposed pinions 26 meshing with racks 24, 25 on the rings 16, 17, the pinion 26 being driven driven through shaft 27, gearing 28 and shaft 29 by an electric motor 30. Rigidly supported boarding platforms 32-35 and steps 36 leading thereto are provided. A central cylinder 37 is fitted with scenic representations and rotated in a direction opposite to that of the inner circle of cars by motor 30 through shafts 43 and one or more pinions 42 meshing with a rack 41 rigid with the wall 37 which is mounted by a footring 38 and rollers 39 on a track 40.

Class 110(iii) In a gas turbine plant which includes a separate output turbine e, the gas supply to the output turbine is controlled by a change-over valve a so that gases either pass to the turbine or by-pass the turbine; an orifice f being disposed in the by-pass and the size of the orifice being such that the pressure drop across the orifice is equal to that across the turbine under the same conditions of mass flow and inlet temperature. In a second embodiment in which the gases are re-heated before passing to the output turbine, two orifices are provided in conjunction with two change-over valves, so that when the turbine is being by-passed, some gas passes through one orifice to a heat exchanger in which air is pre-heated before passing to the main combustion chamber, while the remainder of the gas passes through the second orifice direct to atmosphere. The quantity of gas passing through the heat exchanger is sufficient to provide the necessary, rise in the air temperature.
Patent GB-159527-A (GB)
Abstract: 159,527. Marks, E. C. R., (National Equipment Co.). Sept. 15, 1919. Disc mills.-The invention consists in the improved construction of reducing surfaces on the faces of discs which may be used in refining apparatus of the type disclosed in Specification 17074/12, and is an improvement on the disc construction disclosed in Specification 133,476; Specifications 20861/14 and 108,331 also are referred to. The disc is cast in sectors r with half. holes 10 for attaching to a backing-plate, each sector comprising a series of angularly spaced radial main feeding-grooves 18 extending from the central feed-opening to the inner boundary of an annular series of pockets 20 on the outer portion of the disc, each main feeding- groove being intersected at an acute angle by many auxiliary feeding-grooves 19 so that the substance to be refined may be distributed in fan-like form from the main feeding-grooves to the outer pockets. The main feeding-grooves have one longitudinal face normal to the outer surface of the disc, the other longitudinal face sloping upward from the bottom of the normal face. These grooves are of gradually decreasing depth and width from the centre of the disc, and are of relatively large dimensions compared with the auxiliary feeding-grooves. The auxiliary feeding-grooves are all substantially of the same width and depth having one normal and one sloping face. They are of progressive lengths and terminate at their outer ends in small progressively increasing distances from the centre of the disc. The pockets are in two series one A, B, C, &c. eccentric to, and the other A-A<3>, B-B<3>, &c. concentric with, the axis of rotation of the disc. The number of pockets in each series increases from the inner boundary which is nearer to the centre than to the periphery of the disc, " filling-in " pockets 21 being placed where necessary. The pockets are parallel to one another and to the auxiliary feeding-grooves and their small dividing-walls 22 stop the flow of the substance directly in a radial direction, their dividing-walls 23 preventing the flow directly in a circumferential direction, the result being that the flow between opposed discs takes place in a sinusoidal form throughout the pockets to the periphery. The half holes 10 have meeting- shoulders 12, and to provide a good bearing upon the cast surfaces a washer 15 is disposed between the shoulders and the head of the fixing bolt, the mating-surfaces of the bolt and washer being slightly curved to compensate for irregularities in casting.
