Title: Process for the production of valuable products, in particular paraffin wax from substances containing bitumen, such as coals, shales and the like
IPC: C10G73/42
Filed: 1935-06-17
Abstract: Paraffin wax is obtained by treating coal, shale, or other bituminous material with such organic solvents and under such mild p  conditions that only waxes, resins and other bituminous materials are dissolved, the asphaltic and phenolic bodies and humic acids being practically neither extracted nor decomposed, and hydrogenating without substantially cracking the extract at 20--500 atmos. and either below or above 300 DEG  C.  The residual coal or like may be destructively hydrogenated.  The extraction is preferably carried out below 300 DEG C. and at 5--200 atmos. pressure, usually with 1--10 parts by weight of solvent for 0,25--4,0 hrs.; it may be in stages, e.g. of rising temperature and/or pressure, and it may be repeated with the same or with different solvents, the extract preferably being removed after each stage.  Solvents specified are benzene, toluene, xylene, tetrahydronaphthalene, ethyl or other alcohol, ethers such as ethyl ether, amyl acetate, acetone, carbon disulphide, chloroform, and carbon tetrachloride.  Hydrogenating gases specified are hydrogen, mixtures of hydrogen and oxides of carbon, hydrogen sulphide, methane, ethane, and other gaseous hydrocarbons.  Hydrogenation of extracted matter, with or without retained solvent, is effected (1) at 200--300 DEG  C., by passing 0,1--3,0 kg. per hr. per litre of catalyst through a reaction vessel containing molybdenum sulphide, tungsten sulphide, or other sulphide of Groups 5, 6 or 8; or (2) at 300--450 DEG  C. with the catalysts finely distributed through the material; suitable catalysts being compounds of metals of Groups 5 and 6, or of tin or of iron, e.g. iron sulphide; or molybdic acid or tin oxalate mixed or not with oxide of zinc or magnesium or other compound of a metal of Group 2.  The catalysts may be on carriers, e.g. coke, active carbon, silica gel, alumina, fuller's or other bleaching earth.  The extract is separated from the residue by decantation, filtration, or centrifuging.

Title: Time division multiplex system
Inventor: GARA GEORGE
IPC: H04J3/04
Filed: 1968-04-10
Abstract: 1,212,902. Pulse modulation circuits; transistor gate and hold circuits. STANDARD TELEPHONES & GABLES Lfd. 10 April, 1968, No. 17377/68. Headings H3T and H4L. In a circuit for demodulating amplitude modulated pulses in a time division multiplex system, the incoming signals are supplied via a transistor VT 1 , gated at the time positions in the multiplex cycle of the channels in use, by pulses applied to its base, to the emitter of a normally cut off transistor VT 3  of one of the demodulating circuits. During the initial portion of a gating pulse, collector current for VT 1  flows via a diode D 1  but shortly after the start, and terminating before the end of these gating pulses, pulses at the corresponding channel time position are applied to the base of a normally cut off transistor VT 2 . This causes VT 2  to conduct and its collector potential to rise to almost + 12 volts so that current flows in R 1  and the base of VT 3  is clamped at approximately + 5À7 volts due to diode D 2  conducting. The emitter of VT 3  will be at about +5 volts so that diode D 1  will be blocked and the current through VT 1  will be diverted to VT 3 , the potential across R 2  being proportional to the amplitude of the input signal and causing capacitor C 1  to be charged accordingly. At the end of the pulse applied to VT 2 , VT 2  and VT 3  are cut off and diode D 1  becomes conductive, D 3  being reverse-biased so that capacitor C 1  retains its charge. C 1  is coupled to an audio-amplifier consisting of a Darlington pair VT 4 , VT 5  filtering being added as required. The transistor connected to the base of VT 1  provides an indication to control circuitry (not shown) as to which time slots are busy and also clamps the base potential of VT 1 .

Title: Improvements in or relating to methods for the oxidation of saturated aliphatic hydrocarbon gases
IPC: C07C47/04
Filed: 1943-10-21
Abstract: <PICT:0606554/IV(b)/1> Saturated aliphatic hydrocarbon gases particularly methane or ethane are oxidized by contacting with sulphuric acid of at least 75 per cent concentration or sulphur trioxide at a temperature of at least 200 DEG  C. and in the substantial absence of free oxygen either in the presence or absence of a catalyst.  Catalysts which may be used are the compounds of the metals having atomic weights above 50 and particularly of the metals of the first and eighth periodic groups.  Specified metals are iron, cobalt, nickel, copper, silver or a mixture thereof and these metals may be supplied to the acid as the metals themselves or as salts or other compounds, e.g. as the sulphates, nitrates or chlorides.  It is preferred to use mixtures of cobalt, nickel or iron compounds with silver or copper compounds.  Natural gas may be oxidized by the process to yield formaldehyde from its methane content and some acetaldehyde as well as some formaldehyde from the ethane present. Methanol is also formed from the methane but its formation is practically negligible at temperatures of 275 DEG  C. upwards.  The process may be carried out by contacting the hydrocarbon gases with sulphur trioxide or with sulphuric acid vapours at high temperatures in an apparatus closed to the air or by using the sulphuric acid in the liquid phase.  In the apparatus shown in the drawing sulphuric acid is supplied through line 7 to an insulated tower 1 which is heated, e.g. by means of electrical resistance elements 4 embedded in the insulating jacket.  The hydrocarbon gas enters the tower through line 2 which passes through a sealed closure at the base of the tower above which a perforated plate 6 supports a packing, e.g. beads or rings of glass or carbon.  The treated gas passes through line 8 and through a cooler and condenser 9 in which the formaldehyde or other oxidation product is condensed.  The cooled products then pass into a container 11 from which the condensate may be withdrawn at will through line 12.  Uncondensed vapours pass into a body of water maintained in a vessel 13 and remaining gases pass into the vessel 15 in which they are washed preferably with an alkaline liquid such as a solution of sodium hydroxide.  Residual gases which consist almost entirely of unreacted hydrocarbons are returned to the reaction tower by a pump 18.  Sulphuric acid may be supplied at intervals or continuously during the operation and in the latter case a corresponding withdrawal of acid takes place through line 21. Concurrent flow of the gases may be employed.  The gases treated may be admixed with carbon monoxide, hydrogen or aromatic hydrocarbons derived from coke oven gas, so long as these contain substantially no free oxygen.

Abstract: 1423781 Electro-physical measurement-fluidflow SYBRON CORP 12 April 1973 [17 May 1972] 17637/73 Heading G1N The invention relates to removing, in three stages, unwanted components from the signal in an M.H.D. flowmeter. For this purpose a pair of voltages are derived between the earthed conduit (or shield) and electrodes 5, 6 respectively. After preamplification these voltages are firstly combined in a differential amplifier 19 to cancel out the common-mode signal and then passed secondly to a phasesense sensitive detector to reject the directly induced quadrature component signal, and thirdly to a dividing circuit 24 having a reference dependent on the magnet-energizing-current to eliminate the effects of variation in the magnet field strength. The preamplifiers 13, 14 are preferably individually screened and potted, and mounted in an outer shield 18 surrounding the amplifiers 19, 20. This outer shield may form part (electrically) of the magnet shield. The details of the preamplifier construction form the subject matter of Specification 1423782.

Filed: 1921-06-29
Abstract: 169,430. Siemens & Halske Akt.-Ges. Sept. 18, 1920, [Convention date]. Signal and like lamps.-In a signalling lamp, red and green sources of light are provided and indications are given by the use of the red source alone or in combination with the green source, the green source being sufficiently strong to render the red light ineffective. T h e sources may consist of electric lamps or lamps having mechanically-operated shutters. As applied to railway signalling, a red lamp 6, Fig. 1, arranged so that its direct rays cannot pass outside the lamp case, throws light on to a matt surface of ground glass, milk glass or the like, so that a red indication is given at an orifice 1 in the case. When a green lamp 7 is brought into use, its rays, meeting the matt surface, are sufficiently strong to predominate over the red rays. Modified arrangements involve the use of prisms. In another form, screens 2, 3, 4, Fig. 4, of clear glass are used, the red light from lamp 6 being reflected from the screen 4, while green light from the lamp 7 passes through the screen 4, predominating over the red light. When electric lamps are used, any form of indicator may be used in the lamp circuits. Lenses may be used between the sources of light and the screens or prisms, or at the orifice of the casing. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention is applicable generally to lamps employing two or more differently coloured light sources, and that indications may be given by the sources in combination or by one source alone, or one source may predominate over the next. The sources mav be of complementary colours. This subject-matter does not appear in the Specification as accepted.
