Title: Compensating fluctuations of gas combustive quality
Inventor: SCHEFFLER PETER
IPC: F23N1/00
Filed: 1968-10-07
Abstract: 1,219,952. Burner controls. KOMBINAT MESS-UND REGELUNGSTECHMK DESSAU VEB. 7 Oct., 1968, No. 47390/68. Heading F4T. Apparatus for compensating the effects of fluctuations in the combustive quality of a fuel gas in a main conduit 1 on the rate of heat output and flame form at main burners 22 comprises a first regulating burner 9 with cone height sensing means 5 operating a valve 3 via a regulator 4 to control the extent of admixture of a secondary gas, e.g. air, hydrogen or a gas having a greater flame propagation rate than the fuel gas, from a conduit 2, with the fuel gas, and a second regulating burner 18, having means 17 sensitive to the rate of heat output of its flame, to control a pressure regulator 15 via a regulator 16 and thus to control the pressure of the fuel gas-secondary gas mixture supplied to the main burners 22 and the regulating burners 9, 18. Throttles 12, 13, 14 and 20, 27, are connected to the burners 9 and 18 respectively to ensure that the cone height and heat output rate are functions of those of the main burner flames. If a secondary gas other than air is used, air is supplied by a separate conduit 27. The cone height sensing means 5 includes a probe conduit 6 having an input choke 7 connected to the secondary gas supply 2 and a nozzle 8 extending coaxially of the burner tube and terminating at a pre-determined height above the end of the burner tube. The size of nozzle 8 varies depending on whether it lies inside the relatively cool core of the flame, or in the hot outer portion, and so give rise to a varying pressure difference between the ends of the probe 6 and a corresponding adjustment of valve 3 is effected by the regulator 4. The means 17 is a heat exchanger transferring heat to a constant flow of a heat carrier e.g. water or air, the temperature of the carrier being converted to a thermo-electric voltage fed to the regulator 16. The main burners, which may have flame retention ports if they are of high output, are fed with primary air via throttles 24. If burners 22 consume relatively little gas, the "feedback" conduit 11 may be replaced by a conduit 25.

Title: Quantity level gauge
IPC: H03M1/00
Filed: 1972-10-20
Abstract: 1393738 Digital level gauge PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 Oct 1972 [25 Oct 1971 12 Nov 1971 29 June 1972 13 Oct 1972] 48406/72 Heading G4H A quantity level guage has a plurality of light emitting indicators, each responding to a different level and means to vary the intensity of at least one indicator in dependence on the level. The quantity is expressed as a voltage and this is applied to a plurality of voltage comparators, each with a different reference voltage and each associated with one of the light-emitting indicators. The embodiment described is a vehicle fuel gauge. Variable resistors 6, 7 operated by a float in the fuel tank provides a base emitter voltage to TR1 from the power supply (1 is positive), as TR1 conducts a voltage proportional to the level in the tank is generated across emitter resistor 3. This voltage is applied to the bases of transistors TR2, TR4, TR5 and TR6 which have lamps 8, 9, 10, 11 respectively connected between their collectors and the positive-rail and the base and emitter resistor and the diodes where appropriate are arranged such that each transistor conducts sufficiently to light the associated lamp brightly at a different predetermined voltage. For example, lamp 8 may be at the desired brightness when the tank is one quarter full, with intensity reducing to zero when the tank is empty. Similarly lamp 9 may be at full brightness with a half-full tank and zero brightness at the quarter-full position. Generator G produces an intermittent voltage which will cause lamp 8 to flash from the intensity determined by TR2 base voltage to full brightness-this flashing becoming more noticeable as the tank level nears zero. This flashing may be applied to any or all of the lamps. The lamps may be connected via a decoding circuit so that only one lights at a time. A circuit with a time constant of 1-10 seconds or hysteresis circuit may be used to damp out fluctuations in input voltage.

Title: Alkylation of isobutane
Inventor: GOLDSBY ARTHUR RAYMOND
IPC: C07C2/62
Filed: 1965-11-26
Abstract: A process for the alkylation of isobutane comprises the steps of (1) contacting used sulphuric acid containing water and oil contaminants with propylene to form a product containing dipropyl sulphate; (2) contacting said product with a paraffinic hydrocarbon (e.g. isobutane) to form a raffinate and an extract comprising dipropyl sulphate and paraffinic hydrocarbon; (3) passing said extract into an alkylation zone in which a major proportion of said dipropyl sulphate is used to alkylate isobutane in the liquid phase in the presence of sulphuric acid alkylation catalyst, free sulphuric acid being liberated; (4) passing at least part of said catalyst containing unreacted propyl sulphates to a separate alkylation zone in which butylene and substantially all of said unreacted propyl sulphates are used to alkylate isobutane; (5) withdrawing at least part of the reaction mixture from stage (4); and (6) separating the withdrawn mixture into hydrocarbon and catalyst phases.  If the paraffinic hydrocarbon used in step (2) is a normal paraffin, all or part of it is desirably flashed from the extract before passing the extract to step (3).  The process economises in H2SO4 since used acid is converted back to 100% acid via dipropyl sulphate.

A method of producing a friction clutch engaging load spring having an annular component of sheet spring metal, one of the radially inner and outer edges of the annular component being movable axially relative to the other to apply or release an axial load, comprises feeding spring metal strip 12 from a reel 11 between rollers 16 and along a circular path between bend rollers 14 and 15 so that successive pairs of bend rollers engage the edges of the strip 12 and bend the strip into a ring with the width of the strip lying radially of the ring. As the leading edge of the strip emerges from the last pair of rollers 16 it is diverted from the vertical so as to be directed alongside the portion of strip extending between feed-rollers 13 and the first pair of rollers 16. The feed rollers 13 are stopped just before the leading end of the strip returns to the first pair of rollers 16 and the single turn of strip severed from the remainder of the strip. The ends of the one turn coil are welded together so as to form a flat ring which is then coned by conventional methods. In a second embodiment the ends are joined by severing the edges so that one of its ends defines a tongue 17 and the other defines a notch 19. In a third embodiment the rollers 16 of each pair are arranged with their axes parallel to one another and at an angle to the vertical plane, the axes of each of the rollers 16 which engage one side surface of the strip 12 lying in a conical surface of revolution. Thus the closed ring formed by joining the ends together will have the required conical shape so that no additional operations will be necessary.
