Title: Electronic timing system for internal combustion engine
IPC: F02P5/155
Filed: 1970-12-14
Abstract: 1327449 Timing ignition FIAT SpA 14 Dec 1970 [31 Dec 1969] 59317/70 Heading F1B [Also in Division G1] Apparatus for controlling the ignition timing of an I.C. engine in accordance with a predetermined relationship between angular speed n, Fig.1, and angle of advance # comprises means for producing pulses i 1 , i 2 , Fig.2, corresponding to points P 1 , P 2  in the cycle, fixed relative to the top dead centre PMS, which are fed to a unit E generating a triangular voltage H, whose amplitude depends on the speed n, which is compared at G with a reference voltage A  s  to produce an ignition pulse i c  at the correct angle when their values are equal. The pulses i 1 , i 2  are produced by the passage of a magnetic stud T on the fly-wheel D past detectors at points P 1 , P 2 . The first pulse i, initiates the side 1 of the triangular voltage H, the second pulse i 2  produces the peak voltage 2 and the other side 3 of voltage H and the amplitude of the apex of the triangle is proportional to the angular speed. Thus, when the descending side 3 of voltage H is compared at G with the reference voltage As it produces an ignition pulse i c  at # o , Figs.1 and 4, when the speed n is zero, at # max  when the speed is n max  or greater, and a desired relationship A o -B between n = o and n = n max . A third pulse i 3  may be obtained at a point P 3 , Fig.2, corresponding to an angle # min , which enables the ignition angle to be maintained at # min  between zero speed and a predetermined lower speed value, Fig.9 (not shown). The ignition angle can also be made dependent on auxiliary parameters e.g. temperatures.

Title: Catalytic reforming
IPC: A63H33/16
Filed: 1969-12-15
Abstract: 1,236,299. Reforming gasoline. TEXACO DEVELOPMENT CORP. 15 Dec., 1969 [30 Dec., 1968], No. 60999/69. Heading C5E. A process for improving the octane rating of hydrocarbons boiling in the gasoline range wherein a mixture of hydrocarbons and hydrogen is passed through at least three reforming zones in contact with a reforming catalyst under reforming conditions and wherein the mixture is subjected to heating between the several reforming zones, comprises (a) heating the effluent from a first reforming zone to provide a mixture having a temperature at the inlet to a subsequent reforming zone which is lower than the temperature T 1  of the mixture at the inlet to the first reforming zone and thereafter (b) providing a feed to a later reforming zone having a temperature at the inlet which is higher than the inlet temperature to said subsequent reforming zone. The catalyst may be platinum or alumina. The feedstock may be light or heavy straight run gasoline or hydrotreated cracked gasoline. Conditions are conventional.
Patent GB-659379-A (GB)
Abstract: 659.379. Generation of fuel gas. NEWBY, H. (Badische Anilin- &- Soda-Fabrik). Oct. 13, 1949, No. 26303. [Classes 55(i) and 55(ii)] ] A process for producing fuel gas from finely divided fuel comprises feeding the fuel with an oxygen containing gasifying agent into a chamber where a partial gasification by the heat of combustion occurs, then passing the ungasified fuel and gaseous products tangentially into one end of a cylindrical gasification chamber proper, the fuel being kept in spinning movement by tangential jets of gasifying agent in the second chamber until it is completely gasified, gas being withdrawn axially from the other end of the chamber. In one form, the apparatus consists of a chamber 3 into which powdered coal, which may be mixed with steam, enters through a pipe 1 whilst an air and oxygen mixture enters through pipe 2, combustion and partial gasification occurring in the chamber. The unburnt fuel and gases pass through a funnelshaped extension 4 of the chamber which leads tangentially into a cylindrical chamber 6. Tangential jets 7 spaced along the chamber introduce further gasifying agent and serve to keep the fuel spinning in the chamber. The fuel is thus completely gasified, the fuel gas produced passing out through an axial opening 8. A temperature of 1700‹C. is produced in chamber 6, this causing slagging of the ash, the slag running off through a tapping hole 9. In an example, the gasification of -5 5 metric tons of brown coal produced 12,500 cubic metres of gas of composition 56 per cent CO and H2; 20 per cent CO, and H20 and 24 per cent N2.

In this arrangement an imperforate diaphragm may alternatively constitute the wall 9. A second embodiment, Fig. 2, has the two sound chambers 13, 18 communicating directly with the compression chamber 10. A diaphragm may optionally seal off the conduit 4, in which case a suitable movement transmitting linkage must be used. Specificaton 653,844 is referred to.

Patent GB-2066298-A (GB)
Title: A method for the production of materials for contact members
IPC: H01H1/02
Filed: 1980-11-13
Abstract: It is the object of the invention to combine in one method the advantages of the powder-metallurgical production and the melting-metallurgical production of materials for contact members of vacuum switches from CuCo, CuFe or CuCr alloys. This is brought about in that CuCo, CuFe or CuCr melt, which latter is in two phases, is degassed, deoxidised and atomised. Depending on the composition of the powders, sintering in the solid state, with a liquid phase or the impregnation of skeleton bodies is possible. By alloying Cr with Cu, there comes about the possibility of the melting-metallurgical degassing in a vacuum induction furnace, since it is not necessary to reach the melting point of the Cr of approximately 1900 DEG C but only the liquidus temperature of the Cu-Cr system of 1470 DEG C has to be reached. Although two melts of different composition arise above this temperature, homogeneous alloys are brought about by the simultaneous atomisation of the two melts.
