Title: Steam Reforming Process to make Fuel Gas
Inventor: NICKLIN THOMAS
IPC: C10G47/00
Filed: 1966-06-22
Abstract: 1,196,413. Making fuel gas. GAS COUNCIL. 14 June, 1967 [22 June, 1966; 22 Feb., 1967], Nos. 27929/66 and 8446/67. Heading C5E. A lean gas, i.e. one consisting essentially of H 2  and CO, is reacted at elevated temperatures in the presence of a nickel-uranium catalyst with steam and a hydrocarbon feedstock under such conditions that the reaction is exothermic or thermally neutral, to produce a gas comprising H 2 , CH 4 , and oxides of carbon. An essential condition of the reaction is that the Operating Ratio (O.R.) is less than 0À06, the O.R. being the Initial Inert Ratio (I.I.R.) divided by the Carbon Ratio (C.R.), the I.I.R. being the proportion, expressed as a fraction, of gases present in the dry lean gas (other than H 2 , CO, CO 2 ), and the C.R. being the ratio of the weight of carbon in the feedstock added to the lean gas to the total weight of carbon content in the lean gas (both referred to a given time). A two-stage process is described, the first stage producing the lean gas by steam reforming a hydrocarbon feed at elevated temperature over a catalyst which may be the same as the nickel-uranium one employed in the second (inventive) stage. The catalyst, which in the second stage may be a fixed or fluidized bed, comprises Ni and/or NiO and U 3 O 8  and/or UO 3 , optionally on a carrier of aluminium oxide or alkaline earth metal oxide, such catalysts being described in Specifications 1,039,206, 1,196,411 and 1,196,412. The final gas may be diluted with lean gas which has by-passed the second stage reactor. Reaction conditions are described in detail for both stages.

Title: Improvements in date indicators
IPC: G04B19/253
Filed: 1937-03-24
Abstract: 478,551. Date-indicators. JISKRA, Z. March 24, 1937, No. 8611. Convention date, March 30, 1936. [Class 106 (iv)] A date-indicator comprises four discs, Figs. 1-4, which carry indicators of the day name, month name, date figure and units figure of the year number, the discs having peripheral teeth which are engaged by an actuating pawl Z, Fig. 9. The discs shown in Figs. 1-3 have apertures for exposing the data on the discs of Figs. 2-4. A fifth disc, Fig. 5, indicates " forenoon " and " afternoon " through an aperture P<4>, Fig. 9, in the back of the casing. The pawl Z is carried by a lever Y, allowed to rock clockwise suddenly every twelve hours. The direction of this rocking is anticlockwise in Figs. 1-6. The pawl Z is spring-pressed against a shaped gap M, Fig. 6, in a fixed plate, the end of the pawl being wide enough to engage the teeth of all the superposed discs, Figs. 1-5. At midday, the pawl engages a shallow tooth 2 of the disc of Fig. 5 and is thus held out of contact with the other discs and advances this disc only. At midnight, a deep tooth 3 on this disc allows the pawl to advance this disc, the day-name disc, Fig. 1, and the date-figure disc, Fig. 3. This last disc advances through a smaller angle than the other two because the portion fg of the gap M in the fixed plate masks the teeth of the said date-figure disc. The date-figure disc has long teeth 30, 31, 1, 2 in operative position at the end and beginning of a month so that this disc is advanced the necessary extra steps at the end of a short month unless the long teeth are masked by the long teeth 1 of the monthname disc, Fig. 2. The teeth of these two discs are so arranged that the dates are correctly altered every day throughout the year. The date figure, in addition to the month name, for the 1st of each month (and also for the 2nd March) is shown on the month-name disc, being advanced on both the first and second days of the month (and also on the 3rd March). At the end of February in a leap year, a high tooth 3 on the year number disc, Fig. 4, is in position to co-operate with the teeth of the other discs to cause 29th February to be indicated.

Abstract: 1,029,887. Automatic speed controls. GENERAL ELECTRIC CO. March 5,1963 [March 7,1962], No. 8701/63. Heading G3R. The armature 10 of a D.C. motor is supplied through controlled rectifier 12 and is connected in series with resistor 14, a parallel circuit comprising inductance 16 and resistors 18, 20. An adjustable resistor 22 is shunted across resistors 18 and 20. A signal indicating the speed of the motor is derived from terminals 2, 5, this signal being applied to comparator 24 which also receives a reference signal. The error signal is supplied to firing circuit 26 associated with the rectifier 12 for varying the conductive periods of the rectifier. The ripple component of the speed-indicating voltage between the terminals 2 and 5 may be reduced by adjusting the magnitude ratio of the resistors 18, 20, 22 to the inductance 16, further correction, if necessary, being effected by adjusting resistor 14. In another arrangement inductance 32 is connected in series with the motor and is extended by a lower winding 34. A portion of the inductive voltage developed across winding 34 is derived from potentiometer 36 adjustment of which reduces the ripple component of the voltage derived from the terminals 2, 5, (Fig 4, not shown).

Title: Improvements in carburetters for internal combustion engines
IPC: F02M7/11
Filed: 1919-04-07
Abstract: 144,830. Dodson, E. April 7, 1919. Spray carburettors.-A comparatively weak mixture at all throttle openings except about the full openings and a rich mixture at the full openings is obtained by providing a conduit between the induction passage and the top of the float chamber, a regulating-member in such conduit, interconnecting the carburettor throttle valve and the regulating member, and providing a manually-controlled air leak from the top of the float chamber to the atmosphere or to the carburettor air inlet. The float chamber 1 is connected to the induction passage by a pipe 10 which may be branched to opposite sides of the throttle valve, as described in Specification 135,956. An adjusting-nipple 16 may be inserted in the upper branch 14. A barrel 11 is inserted in the pipe 10, and contains a spring-loaded plunger 12, Fig. 2, actuated from the spindle of the throttle valve 6 through a cam 7. The plunger has in its lower end a slot 24 which works in conjunction with a recess 25 to control the flow of air. The air leak is controlled by a cock 21 from which a pipe 20 passes to the top of the float chamber and a pipe 22 preferably to the air inlet 4. The cock 21 may be near the driver and provided with a dial 34 and pointer 35 to indicate the extent of its opening. The cock, which may be actuated from the throttle valve, provides a restriction which is long in proportion to its bore, and is constructed as shown in Fig. 3. The periphery of the plug cock 30 is grooved at 31, and the air has to pass through this groove except when the cock is fully open, at which position the air passes directly from pipe 20 to 22 through radial and axial bores. To prevent leakage due to corrosion, the barrel 11 is made of bronze and the plunger 12 either of rustless steel or of ordinary steel impregnated with a non-corrodible metal. In a modification, the pipe 10 communicates with the induction pipe through a permanently open calibrated orifice in the trunnion of a barrel throttle valve, the trunnion being also ported to control the air flow. In a further modification, the pipe 10 is controlled by a plug-valve actuated from the throttle valve through linkage mechanism. In a still further modification, the plunger may be actuated through a wedge-shape member adjustable along a slot in a lever by which it is carried.
