Title: Improvements in or relating to carbonisation of coal and other carbonaceous material
IPC: C10B49/04
Filed: 1925-03-13
Abstract: 231,159. International Combustion Engineering Corporation, (Assignees of Runge, W.). March 21, 1924, [Convention date]. Coking and carbonizing processes.-Powdered coal or other carbonaceous material is carbonized by showering through a rising stream of hot combustible gases, the volatile products being withdrawn together with the hot gases at the upper part of the carbonizing zone which is maintained at a temperature not above 1500‹ FA finely-divided semi-coke is obtained. The gases introduced have a calorific value of at least 125 B.T.U. Powdered coal from a hopper 52 is fed through a depending shell 48 having a fan 50 into the vertical retort. Hot gas from a producer 6 is passed through a dust remover 8 and heater 10 to a chamber 29 in the lower part of the retort and rises through the retort in counter-current to the falling coal. The gases and vapours pass into an annular space between the retort jackets which acts as a dust depositing chamber and are led by a pipe 38 to n dust separator 14, washer 16, hydraulic main 18, and condenser 20. The residue is discharged into a cooling chamber 4 acting as a heat exchanger through which a fluid such as air may circulate to be heated. Air thus heated is employed in the burners 22 of the heater 10 and is also passed by a pipe 21 into the jacket of the dust separator 14 to prevent condensation therein. To increase the temperature of the gases in the retort jacket a pipe 58 conveys the hot gas directly by branch pipes 60 to the jacket and branch pipes 61 are provided to introduce these gases into the retort. In a modification the retort jacket may be supplied with heated air and the distillates passed direct to the cleaning plant and the hot producer gas may be admitted tangentially to the inner walls of the retort so as to produce a whirling motion.

Filed: 1930-03-05
Abstract: 350,387. Ornamenting pencils. ANGLO PENCIL CO., SMITH, M., and PRITCHETT, R., Bank Chambers, Pelham Street, Nottingham. March 5, 1930, No. 7167. [Classes 93 and 146 (iii).] Pencils and like articles are ornamented by providing the surface with a sensitized coating, and passing the articles in succession through an apparatus for exposure under a negative, the prints being subsequently developed and fixed, and toned if desired. A matt surface of pigmentized cellulose ester and gelatine varnish may be provided as an undercoating on which the gelatine or collodion sensitizing emulsion is applied. Finally a coating of nitro-cellulose varnish is applied to protect. the print. In the apparatus shown, the pencils 2 are fed from a hopper 8 by means of a plunger 3 reciprocated by solenoids 4, 5 alternately energized when a brush member 19 contacts with contact elements 20, 21 mounted on a rotating drum. The pencil is pushed from the hopper 8 between oppositely-rotating feed-rollers 9 into the printing- chamber 10, and a negative 12 is brought down into contact therewith by the action of solenoids 14, the circuit being completed by the brush 19 and a strip 22 on the drum. Further rotation of the drum causes the member 19 to make contact with a strip 23, thereby lighting a lamp 16 to make the exposure. Subsequently the brush moves out of contact with the strips 23, 22, thus permitting the negative to move upwards under spring action, and the exposed pencil is ejected by the incoming pencil. Mechanical means may be substituted for the electrical means described. Dipping-machines such as are described in Specification 325,638, [Class 95, Paints &c.], may be used for applying the sensitized emulsion, and for developing and fixing.

Filed: 1976-03-12
Abstract: 1497562 Machine tool control A TACK 12 March 1976 [25 Feb 1975] 7846/75 Heading G3N A control device for a machine tool computes feed increments for successive passes by forming a mathematical combination of a stored feed increment and a constant. The constant can be subtracted from the increment to give a series of corrected increments forming an arithmetic progression or the constant and increment can be multiplied, the constant being less than one, to give a series of corrected increments plotted as a decreasing exponential curve. The increment and constant are stored in analog or digital form and can be manually set on a panel Fig. 3 (not shown) with an LED display 29. Digital stores 31, 32, 33 receive the total, increment and constant from switches 21, 22, 23 on the panel. A signal appears on line 34 at the end of a machining pass to multiply the increment by the constant, the product in accumulator 35 being written back in store 32 as the new increment. The product is also subtracted from the total feed 31. The machine tool can be a relieving, screw cutting or grinding lathe, a milling or a grinding machine, and tool drive is effected by a stepping motor controlled by pulses from gate 40 until comparator 43 indicates that the increment in accumulator 35 has been reached. The angle of the cut α Fig. 1 (not shown) is set via switch 26 in store 44 and this controls the X, Z feed directions.

Title: Process for the synthesis of hydrocarbons from mixtures of carbon monoxide and hydrogen
IPC: C07C1/04
Filed: 1939-03-11
Abstract: 526,814. Gas purifying processes. POTTS, H. E. (Naamlooze Vennootschap Internationale Koolwaterstoffen Synthese Maatschappij). March 11, 1939, No. 7909. [Class 55 (ii)] [Also in Group IV] Gases containing carbon monoxide and hydrogen, obtained by the gasification of carbonaceous materials and intended for the synthesis of hydrocarbons containing two or more carbon atoms, are freed of their organic sulphur content by heating them to a temperature of at least 1000 ‹C. and removing the hydrogen sulphide formed. The impairment of the activity of the catalyst used for the synthesis is thereby reduced. The heating is carried out in heat accumulators or exchangers, which preferably contain filling material such as burnt lime, burnt dolomite or bauxite. Preferably the gases are kept in the hot zone for a period of 0.5 to 1 second. The heat may be supplied to the zone directly, or indirectly by introduction of oxygen for regulated combustion of part of the gases. According to the examples (1) water gas obtained by the gasification of brown coal is passed at 1200 ‹C. over bauxite at such a speed that it remains 0.5 second in the hot zone ; the hydrogen sulphide is removed by means of iron oxide. (2) a carbon monoxide-hydrogen mixture obtained by gasifying brown coal with oxygen is passed at 1100‹C. over quartz fragments, the gas remaining 3/4 second in the hot zone; after passage over iron oxide to remove hydrogen sulphide; the gases are used for hydrocarbon synthesis. In each case a better yield is obtained than when the gases are purified only by contact with alkalized iron oxide at about 300‹C. and the life of the catalyst is increased. Specification 14200/09, [Class 55 (ii)], is referred to. The Provisional Specification gives minimum temperature of 800‹ C. and refers to the simultaneous removal of the hydrogen sulphide.
