Title: Pulse feeding catalytic conversion process
IPC: B01J8/00
Filed: 1959-01-22
Abstract: By means of a process in which pulses of feed material are periodically introduced into a "carrier" (i.e., a gaseous or liquid medium) which passes continuously through a catalytic conversion zone, olefin, aliphatic and naphthenic hydrocarbons may be dehydrogenated (and optionally isomerised or alkylated) using a catalyst comprising (a) chromia, molybdena or palladium or platinum supported on, e.g., alumina, or (b) Fe2O3, Cr2O3 and K2CO3. Conversions specified are propane, butane, butenes and cyclohexane, respectively, to propylene, butene, butadiene and benzene; n-pentane to isopentene to isoprene; methylcyclopentenes and methylcyclopentanes to cyclohexanes and aromatic hydrocarbons; and propane or propane/butane mixtures to C6-8 hydrocarbons.ALSO:<PICT:0847768/III/1> An inert or reactive carrier such as a gaseous or liquid medium is continually passed through a catalytic conversion zone, and pulses of feed material are periodically introduced so as to obtain continuous separation of at least a portion of at least one conversion product, the conversion products being thereafter recovered from the carrier.  The carrier and reactants may be liquid or vaporous.  The process may be applied to dehydrogenation of aliphatic hydrocarbons such as (a) butylene, preferably with a Fe-Cr-K oxides catalyst, e.g. at about 700-800 DEG F., and (b) a paraffin, e.g. butane, with an Al-Cr oxides catalyst at about 850-900 DEG F.; catalytic separation of deuterium from HD is also mentioned.  The carriers specified are:- (i) reactive with feedstock-ammonia in aminolysis, water or steam in hydrolysis; (ii) inert gas-nitrogen, helium (in examples), steam, flue gas, carbon mono- and di-oxide, oxygen, hydrogen, hydrogen sulphide, hydrocarbons; (iii) inert liquid-benzene, liquefied butane, water, alcohols and ethers.  Catalysts mentioned, other than under (a) and (b), are chromia, molybdena, Pt-alumina or Pd-alumina, while the following catalyst compositions are specified: (1) Fe2O3 (70-80, e.g. 71%) -Cr2O3 (3%) -K2CO3 (17-27, e.g. 26%; (2) Cr2O3 (3.7%) -Al2O3 (96.3%).  Fig. 4 shows a reactor which may be used in carrying out the process of the invention:- into the annular conversion zone 20, a carrier fluid is introduced by lines 25, 30, while the distributing arm 36 introduces feed material as it is rotated, whereby the feed components form a flow path through the said zone which is in the form of a helix, the carrier fluid and conversion products being withdrawn through line 40.

Title: Composite article and method of joining preformed parts to form such article
IPC: C03C10/00
Filed: 1957-01-23
Abstract: 822,272. Joining ceramic articles. CORNING GLASS WORKS. Jan. 23, 1957 [Feb. 1, 1956], No. 2484/57. Drawings to Specification. Class 87(1) [Also in Groups XXIII and XXXVI] Preformed ceramic parts are joined together by sealing glass which is subsequently devitrified. The sealing glass should be a soft glass, and when used for joining glass parts, e.g. the panel and funnel of a cathode ray tube, should have a softening temperature at least 40C. below the sealing temperature and preferably below the annealing temperature of the glass parts. It may be applied to the parts to be joined by powdering and mixing with a binder to form a suspension, coating the parts and subsequently heating. After formation of a seal by heating the assembly to a predetermined temperature the sealing glass is devitrified by heating it for a further period either at the sealing temperature or a higher temperature, depending on the type of glass, until at least part of the glass is converted to a crystalline phase. The method is described in detail for several types of joint; compositions of suitable lead-zinc-borate sealing glasses are given together with information on the use of stress evaluations from birefringence measurements for the selection of suitable glasses and temperatures. Specifications 613,896 and 629,049 [both in Group XXIII] are referred to.

Title: Improvements in or relating to gear changing apparatus
IPC: F16H35/14
Filed: 1930-01-24
Abstract: 334,823. Lildal, J. J. Jan. 25, 1929, [Convention date]. Controlling variablespeed gearing.-Gearshifting upon a vehicle is selected by depressing one of a number of levers 1, Fig. 3, and effected by effort from a constantly - driven shaft 60, Fig. 2, through a one-revolution clutch 10. The levers 1 act through cables &c. 2 upon lift levers 4, Fig. 1, for the different speeds, and a lift-lever 3 for neutral. The levers 4, 3 are loose upon a rockshaft 5 to which is 'secured a bar 6 normally resting upon these levers. When any one lever 4, 3 is lifted, the bar 6 is raised, rocking shaft 5, which through a linkage 9 puts in the clutch 10. If one of the levers 4 has been lifted, one of a set of pawls 45, Figs. 2 and 6, is raised into the plane of one of four springs 69 on two T-shaped levers 34a, 35a, Fig. 1, which serve to move two gear selector bars, not shown, into positions 38, 40, 41 and 42, 39, 43 respectively. The pawls 45 are loosely pivoted on a shaft 46, which is thrust to the right of Fig. 6 through a bell crank lever 50 when cam 21 turns once. The engagement of clutch 10 causes shaft 15 to turn once only, an element 12, Fig. 1, and a spring terminating the movement. Cams 21 and 16 are thus turned. Cam 16 disengages the main or engine clutch and regulates the fuel supply to the engine. Cam 21 moves the pawls 45 simultaneously and also first brings the change gearing to neutral. This neutralizing is effected by a push-rod 23, Fig. 2, which strikes a nose 72 on a plate 70, Fig. 6, which pivots at 71 and strikes projections 68 on the four short arms of the levers 34a, 35a, Fig. 1, and brings these levers to neutral. In the subsequent group movement of the pawls 45, the one that has been selectively raised strikes a snug 69 and turns one of the T levers to operative position as in the case of lever 34a, Fig. 1. If instead of one of the pawl-lifting levers 4, the blind lever 3 has been raised, the rod 23 alone acts to leave the gearing in neutral. At the end of the power effort, the lever, pushbutton &c. 1, Fig. 3, is raised to indicate completion. The change is facilitated and cushioned by a spring drive in shaft 60, inclines on the ends of pawls 45, and springs in links such as 36, 37, Fig. 1.

Title: Method for flattening the curve of evolution of heat of fuel elements within the core of a fast reactor
IPC: G21C1/02
Filed: 1976-01-22
Abstract: 1510432 Reactors ELECTRICITE DE FRANCE SERVICE NATIONAL 22 Jan 1976 [10 Feb 1975] 02540/76 Heading G6C In a method for flattening the curve of evolution of heat of fuel elements within the core of a fast reactor, wherein the core is constituted by vertical fuel elements each having an axial passage of sufficient diameter to permit the flow of molten fissile material in the event of a power excursion, the diameter of the axial passage is reduced from the elements of the control region of the core to the peripheral elements, the reduction in diameter being proportional to the reduction in neutron flux density. The method can be employed as a complement to the conventional method of producing a variation in the degree of enrichment or as a substitute for this method by retaining a constant enrichment. Each fuel element, Fig. 3, comprises a metallic can 12 housing fissile material 14 in which is formed a hollow axial passage 16, and is provided with a solid upper blanket 18 and a lower blanket 20 constituting a first catchpot 22. A second catchpot 26 of refractory material is located at the extreme lower end of the fuel element, forming the base of a fission-gas expansion chamber 24. The fissile material 14 may comprise a stack of pellets of UO 2  or mixed UO 2 -PuO 2 . The diameter of the axial passage progressively decreases between the centre, 28, of the fuel element and the lower end, 30, of the fissile material 14. This decrease in diameter is such as to maintain the maximum temperature of the fuel below a predetermined temperature. In the event of a fast power excursion, the temperature and pressure of the gas within the passage 16 increase much faster than those of the gas within the catchpot 22 and the chamber 24. The gas is thus impelled downwards, with the result that the fall of molten fuel under the action of gravity will be considerably accelerated particularly at the level of the effective nozzle at the lower end of the fissile material 14.

Title: Improvements relating to gaseous fluid flow systems operating in supersonic velocity conditions
IPC: G01P5/14
Filed: 1945-02-01
Abstract: 603,155. Gaseous fluid flow systems operating under supersonic velocity conditions. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and SMITH, A. G. Feb. 1, 1945, No. 2611. [Class 4] [Also in Group XXXV] In a gaseous fluid flow system in which, when operating at the design point, velocity conditions obtain giving rise to a shock wave, means are provided for measuring the static pressure at two spaced points in the direction of flow, one on either side of the position at which the shock wave forms, and for controlling the conditions of operation of the system in accordance with the indication of the pressuremeasuring means to maintain a low and a high pressure upstream and downstream of the points respectively. Fig. 1 shows a supersonic wind tunnel with static pressure orifices A, B, C, of which B and C are located so as to include between them the zone in which the shock wave at the junction of the supersonic and subsonic sections form, and A is located well upstream of the zone, while Fig. 2 shows an aircraft wing with a variable-area air inlet 26 for operating under supersonic velocity conditions. The size of the air inlet is varied by pivoted flaps 27, and static pressure leads A, B, C are formed in a central casing 29. In each case, under normal conditions with the shock wave D located between B and C, the points A and B are at the same pressure, lower than that at C, but if conditions are such as to cause the shock wave to move upstream between A and B the pressure at A remains unaltered while the pressure at B rises to the value at C. The pressure orifices A, B, C may be connected to gauges, and the speed of the electric motor 3a or the jacks 28 controlling the flaps 27, controlled manually in accordance with the indications of the gauges. Fig. 3 shows an automatic control system in which the orifices communicate with pairs of capsules 5, 6 and 7, 8 respectively, which are interconnected by rigid links 9, 10 operating, through links 11, 12, switches 17, 22 which operate a device F for controlling the speed of the compressor motor 3a or the setting of the jacks 28. The circuits made by the switches 17, 22 are determined by the positions of the links 11, 12 in accordance with the pressures communicated to the capsules 5, 6, 7, 8.
