IPC: C01B3/12
Filed: 1972-08-07
Abstract: 1400065 Hydrogen-rich gas SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 7 Aug 1972 36809/72 Heading C5E A hydrogen-rich gas is produced by subjecting carbon monoxide and hydrogen-containing gases and steam to catalytic co-shift conversion in at least two stages in series with intermediate cooling between the stages, part of the gases by-passing the first stage(s) in the series and passing directly to the subsequent stage(s). The conversion may be carried out in at least three stages in series, at least the first two stages operating at high temperature, e.g. 325 to 600 C., and the last stage operating at low temperature, e.g. 175 to 325 C., part, e.g. 10 to 90% by volume, of the gases by-passing the first stage(s) and passing directly to the subsequent high temperature stage(s). Elevated pressures may be used. All the steam may be introduced into the first stage. Intermediate cooling between stages may be carried out by heat exchangers and/or boilers, or by water injection. The gases may contain more than 10% by volume carbon monoxide and may be obtained by the partial combustion of carbonaceous material. The percentage of carbon monoxide in the gases entering the low temperature stage is less than 5% by volume on a dry gas basis and less than 2% in the hydrogenrich synthesis gas leaving that stage. The shift catalysts may be metals of Groups VIb, VIIb and VIII or oxides or sulphides thereof and various carriers are named.

Title: A combination of a peltier cooling unit with a dry rectifier
IPC: F25B21/02
Filed: 1959-10-30
Abstract: 908,476. Semi-conductor devices. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Oct. 30, 1959 [Nov. 3, 1958], No. 36903/59. Class 37. The current through a rectifier is used to produce a Peltier cooling effect on the rectifier itself. Fig. 2 shows a PN junction rectifier consisting of an electrode 6 to which an N-type germanium plate is soldered with an antimony solder to form an ohmic connection and an indium counter electrode 8. Arms 9 and 10 are soldered respectively to electrode 6 and to the counter-electrode. Arm 9 is a solid solution of bismuth telluride and antimony telluride of P-type while arm 10 is an N-type solid solution of bismuth teluride and bismuth selenide. Copper heat-exchanging arms 11 and 12 are soldered to arms 9, 10. Forward current through the rectifier causes the junction between 6 and 9 and 8 and 10 to act as the cold junctions and the junctions 9, 11 and 10, 12 as the hot ones. The barrier layer should be as close as possible to the carrier electrode. This may be done by using P-type germanium for plate 7 or by using a different type of solder. The arms of the cooling elements may be soldered direct to a semi-conductor body to provide N- or P-type conductivity (Fig. 3, not shown). Adjacent dry rectifier 18, 19 may have a common heat-exchanger (Fig. 4) and the carrier electrode of the rectifier may be extended to form a large cooling arrangement for cooling spaces adjacent the rectifier.

Title: Pneumatic method and device for an internal combustion engine braking and re-starting in the opposite direction
IPC: F02N9/04
Filed: 1975-09-11
Abstract: 1516523 Starting, stopping and reversing internal combustion engines SOC D'ETUDES DE MACHINES THERMIQUES 11 Sept 1975 [26 Sept 1974] 37337/75 Heading F1K The invention relates to a method of braking an internal combustion engine and starting it in the opposite direction. The engine is provided with a compressed-air starting system comprising a starting air master valve 5 supplying the cylinders 11 through their individual starting valves 9 and connected to a source of compressed air 1 which is itself connected through a cut-off or isolating valve 17 to a pilot compressed-air distributing device 14 driven mechanically from a camshaft of the engine in order to alternately supply and discharge sequentially the pneumatic single acting actuators 44, 45 for opening the starting valves which are adapted to be closed automatically by means of return springs 47. The method consists of successively discontinuing the feeding of the engine with fuel, shifting each cam-shaft to a position for running the engine in the opposite direction, opening the cut-off valve or isolating valve 17 while keeping the starting air master valve 5 closed during the period of slowing down of the engine and then in opening the starting air master valve 5 after the engine braking is achieved and further preventing or obturating the exhausts 27 of all the starting valves in order in a manner known per se, keeping the latter under the pressure of pilot compressed-air and locking them in the open position during the whole braking period in order to slow down the engine by the pumping effect of compressed-air acting on the pistons of the engine via the open starting valves 9 and opening the starting air master valve 5 as well as the exhaust of the starting valves when the engine has slowed down to a rotary speed at which the braking by the starting main compressed air becomes more efficient then the braking by the pumping effect. An obturating valve may be provided on each exhaust conduit 27 of the pilot compressed-air distributing device 14 and control means may be provided for the starting air master valve and each obturating valve which control means is monitored or slaved by engine rotary speed detecting means.

Title: Improvements in or relating to the removal of iron impurities from aqueous solutionsof sodium carbonate and bicarbonate
IPC: C01D7/26
Filed: 1955-12-30
Abstract: Iron impurities, for example in the form of colloidal hydroxide or ferrite or ferrate, are removed from an aqueous solution of sodium carbonate and/or bicarbonate by the addition of a metal sulphide. The aqueous solution may be a complex liquor bled off from a cyclic process for the production of sodium sesquicarbonate.  Metal sulphides specified are those of lithium, sodium, potassium, zinc, strontium, barium, calcium, lead, bismuth, cadmium and nickel.  Where a substantial proportion of sodium bicarbonate, e.g. 5 per cent, is present, the molecular proportion of metal sulphide to iron impurity should be at least 3 to 1, and may be as much as 10 to 1.  A ratio of 4-6 to 1 is preferred.  The temperature may be in the range room temperature to 200 DEG  F.  The use of temperatures below 125-130 DEG F. result in greater removal of iron, while the use of temperatures above such temperature result in increased speed of reaction and filtration rate.  Mild agitation may be employed.  The reaction time may be 15 mins.  A coagulant and filter aid, e.g. zinc oxide, lead oxide, magnesium chloride, calcium chloride, or barium carbonate may be employed.  0.1-1 per cent of a saturated solution of calcium chloride is suitable.  The coagulant and filter aid may be added 2 or more minutes before the metal sulphide.

Patent GB-380468-A (GB)
Abstract: 380,468. Anti-aircraft gunnery. VICKERS-ARMSTRONGS, Ltd., WATSON, J. P., and PARKER, S., Vickers House, Broadway, Westminster. March 16, 1931, No. 8103. [Class 92 (ii).] Relates to anti-aircraft sight-correcting apparatus as described in Specification 236,250, [Class 92 (ii), Ordnance &c.], in which the vertical and lateral deflections d, D for speed of target are calculated from the following equations :- Sin d = RE (ST cosec Sp) Sin D = RT (ST cosec Sp) X cos Sp Sec Sf where RE and RT are the angular rates of elevation and training, Sp and Sf the present and future angles of sight, and ST the product of Sin Sf and the time of flight. According to the present invention, the displacement of a member in accordance with ST is utilized for the mechanical interpretation of the factor (S1 cosec Sp) which is common to both formulµ, and the result is combined with the other factors involved in determining the said deflections. As in the prior Specification, handles b, c are rotated in following the target in elevation and azimuth and the members so marked on the drawing are rotated in accordance with the factors RE, Rt and Sp. The calculated deflections d, D appear as movements of pointers B<9>, C<6> which are counterbalanced by movements conveyed to the pointers through differential gears B<8x>, C' by operating handles d, D which control motordriven variable-speed gears d<3>, D<2> and register the deflections on dials d<x>, D<x>. In the present invention, a shaft E<1> is rotated in accordance with the factor ST by combining, through a differential gear E<6>, a movement in accordance with target height set by handle E<2x>, with a movement obtained from a cam E<x> which is rotated in accordance with Sf and translated in accordance with target height. The product ST cosec Sp appears as a sliding of a member B5 which is influenced by a lever B<4> adjusted in accordance with ST, and by a cam B<2> and slide B<3> in accordance with cosec Sp. The movement imparted to the member B<5> is communicated to rollers B<6> and C<2> and is thereby introduced into the calculation of both Sin d and Sin D. The factors cosec Sp and sec Sf are introduced by the cam c<10> and the slide c<7> respectively which combine to influence a roller C3 in the calculation of Sin D. For the more accurate calculation of Sin d, the complementary error may be introduced by the apparatus F. The fuze settings are determined by a cam G rotated in accordance with Sf and displaced axially in accordance with ST. If desired, the major portion of the fuze setting may be calculated by multiplying linkage H‹, Fig. 4, in accordance with the range (H cosec Sf) where H is the target height, the small correction necessary at any point of the trajectory being applied to the fuze dial h through a differential gear H7 by a cam H<8>.
