Title: Method for the utilisation of methane
IPC: C01B3/36
Filed: 1926-01-28
Abstract: 247,176. Patart, G. Feb. 7. 1925. [Convention date]. Void [Published under Sect. 91 of the Act]. Methyl alcohol; oxygenated organic compounds.-Mixtures of carbon monoxide and hydrogen for the catalytic production of methyl alcohol and other oxygenated organic compounds are obtained by the incomplete combustion of methane. The methane is mixed with about one-half its volume of oxygen and the mixture injected into a mass of coke maintained at a high temperature of about 1000‹ C. The coke may be replaced by wood, charcoal, coal, or a refractory substance. The gases pass, preferably in a horizontal direction, through two nozzles which are symmetrically disposed at the lower part of a chamber containing the incandescent mass. It is advantageous to preheat the injected gases, preferably at the expense of the heat of the issuing gases; the nozzles may be protected by water circulation. The issuing gases consist substantially of carbon monoxide and hydrogen in the volume proportion of 1 : 2, but a deficiency of hydrogen may be made up with fresh gas. Usually the heat produced by the combustion suffices to maintain the reaction temperature; if not the percentage of oxygen employed may be slightly increased to effect combustion of a part of the fuel. The ash from this combustion may be either withdrawn by the gas current, or melted by periodic injection of excess of oxygen, preferably in presence of a flux, and discharged in the molten state. The methane may be obtained from natural gas or coal distillation gases, or may be separated from the products obtained in the methyl alcohol synthesis itself.

Title: Scanning means for central-controlled telecommunication, particularly telephone exchange systems
IPC: H04Q3/54
Filed: 1968-01-18
Abstract: 1,162,934. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 18 Jan., 1968 [25 Jan., 1967], No. 2693/68. Heading H4K. In a remote concentrator, monitoring of subscriber's lines is effected by a scanner of the last-work type located in the concentrator and effective to inform a central control located in the main exchange only of the conditions (a) calling line, and (b) hang-up at end of call. The scanner comprises two ferrite core stores one of which contains the condition of each line at the last scan while the other one contains the current line condition. Suitable logic effects a slight delay in the scan cycle if a change of condition is found so that the new condition can be stored in the last look store. The identity of the subscriber is transmitted to the main exchange by marking tens and units (order) wires and a 0 or 1 bit is sent over another order wire to identify the type of change detected. Comparison between the present state and last-look stores is inhibited, during dialling, if the caller does not dial within a set time, or if the line circuit is held (as by noise) even though the subscriber has hung up. The main exchange may incorporate buffer stores so that information from a plurality of simultaneously scanned concentrators can be dealt with successively. The use of reed relay or cross-bar switching networks is envisaged.

Abstract: 469,808. Centrifugal separators. REFINING, Inc. Jan. 31, 1936, No. 2963. Convention date, Aug. 1, 1935. [Class 23] Materials which do not readily flow at ordinary temperatures are separated from liquids in a centrifugal bowl, to which external heat is applied to overcome the normal refrigerating effect due to the rotation of the bowl, so that the material slips uniformly along the bowl wall. The method is particularly applicable to the separation of soap stock from glyceride oil treated with alkali. The flange 3 of the frame 1 supports ball bearings 45 carrying the shaft 38 with a flanged top 37 to which the centrifugal bowl 14 is secured. Cylinders 30, 31 are arranged inside the bowl to increase the distance travelled by the liquid. The neck of the bowl is carried in a spring- mounted bearing 23. The bowl is supported in a closed chamber in the frame, to which steam is admitted by the pipe 50, while the condensate leaves by one or more outlets 51 placed above the flange 3. A heating coil 52 with an inlet 53 and an outlet 54 may also be located round the bowl. The mixture enters by the pipe 25 and passes through the passages 29 into the lower part of the bowl 14. The heavy soap stock slips upwardly on the warm bowl wall and passes through the passage 59, between the cover 15 and a conical member 16, to the outlet 201 and the pan 7. The separated oil passes inwardly through the openings 33, down and up the insides of the cylinders 31, 30 to the space 19<1> and the pan 5. Gum may be added to the mixture supplied to vary the surface tension of the soap stock against the bowl wall. The neck of the bowl may be heated by a steam pipe 57. The flange 37 forms an umbrella shield to protect the bearings 45 which are lubricated by oil supplied through a pipe 46 and drained by a pipe 47. Links 9 pivoted on lugs 10 hold the collecting pan 7 to lugs 11 on the frame 1.

Abstract: <PICT:0378374/III/1> <PICT:0378374/III/2> Plastic edible dairy products such as cheese and butter are pasteurized by heat produced by mechanical working of the product e.g. by passing the product through a constriction resulting in the production of heat by frictional action, homogenization being simultaneously effected. Cheese and like solid products are ground or shredded before the treatment.  In the example given, the material 46 is fed into a hopper 10 from which it passes to between a fixed surface 27 and a rotating surface 39 formed on a disc 28 secured to a shaft 25 rotated at high speed from an electric motor.  The surfaces 37, 39 are spaced slightly apart to define a minute constriction on passage through which the required heat is generated in the product.  The constriction can be adjusted in size to vary the temperature produced by raising or lowering disc 28, which slides on an extension 27 of the shaft 25, by a nut 40 engaging a thread on the shaft, a washer 42 and a lock-nut 44 being provided.  Longitudinal movement of shaft 25 is prevented by means of a sleeve 26 adjustably secured thereto by a narrow screw 43 and engaging a bearing 23.  Curved grooves 45, Fig. 3, may be provided on the surface 39 of disc 28 together with correspondingly formed and directed grooves on the surface 37. The grooves 45 extend to beyond the hopper orifice 38 to affect travel of the product through the constriction even when surface 37, 39 are in direct contact.  The pasteurized product is discharged to a removable container 53, a scraper 49 removing the product from the rotating disc 28.  Apparatus for use in the process forms the subject-matter of Specification 378,376.
