Title: Conversion of gaseous olefins to motor fuel
IPC: C10L1/02
Filed: 1955-02-16
Abstract: Light olefins are converted into products including a gasoline-range liquid by a process which comprises introducing an olefinic feed mixture containing 40-80 mol. per cent of C3-C4 olefins and 60-20 mol. per cent of an inert diluent together with 0.2 to 3 mols. of water per mol. of olefin into a hydration zone containing a hydration catalyst under conditions conducive to reducing the olefin concentration in the unconverted feed to less than 50 mol. per cent while converting at least 20 per cent of the feed olefin into a partially oxygenated liquid boiling between 50 DEG  and 220 DEG  C., passing at least an olefin-containing portion of the effluent from the hydration zone to a polymerization zone containing a polymerization catalyst under conditions conducive to converting at least 90 per cent of the unconverted olefin into polymer gasoline boiling between 50 DEG  and 220 DEG  C., and separating low-boiling products from gasoline-range liquid.  In a preferred embodiment a feed consisting of 60 mols. of propylene and 40 mols. of propane is mixed with 60 mols. of water and hydrated at 1700 p.s.i.g. and at 225 DEG  C. in the presence of pelletized reduced tungsten pentoxide. The crude product is expanded to a pressure of 300 p.s.i.g. and the gasoline range hydration product separated off.  This may consist of 55-96 per cent of isopropyl alcohol, 3-35 per cent of diisopropyl ether, 0 to 10 per cent of acetone and 1 to 25 per cent of propylene polymer, and may be used directly as a motor fuel or may be blended with virgin naphtha, thermally or catalytically cracked gasoline, reformed or hydroformed naphtha, alkylate, polymer gasoline, hydrocodimer or tetraethyl lead.  The unconverted feed consisting essentially of 49 mol. per cent of propylene and 51 mol. per cent of propane is recompressed to 1000 p.s.i.g. and is polymerized in the presence of kieselguhr impregnated with phosphoric acid to form C6, C9 and C12 polymers boiling between 55 DEG  and 205 DEG  C.

Title: Improved device for recording the warp of railway tracks
IPC: B61K9/08
Filed: 1932-02-19
Abstract: 385,780. Recording-apparatus. MAUZIN, A. E., 41, Boulevard de la Gare, Paris. Feb. 19, 1932, No. 5024. Convention date, Jan. 18. [Class 106 (iv).] Recording by co-ordinates.-The warp of a railway track is obtained by recording the variations in the vertical distance between the centres of two tensioned cables connected respectively to the diagonally related wheels of a vehicle bogie running on the track. The bogie axles are extended at 5.. 8 and carry ball-bearings 9.. 12 to which are diagonally attached the ends of cables 45, 46 respectively The latter pass over pulleys 21 rotatably mounted in carriages 13, 14, Fig. 3, slidable in vertical guides 19, 20 and biased by springs 44 to maintain the cables tensioned. The vertical displacement between the carriages, variations in which thus indicate the warp, is recorded by means of a Bowden wire 22 connected to carriage 14 ; the sheath 23 thereof is connected to carriage 13, and the other end of the wire actuates a stylograph 26, Fig. 2. The ballbearings 9.. 12 may be laterally slidable in bushes forming the connecting points for cables 45, 46, the bushes being fixed relative to the bogie frame. Should the warp exceed the tolerance limit, a contact 35 of the stylograph closes at 36, Fig. 5, the circuit of a magnet 37 the armature 38 of which permits a clockworkactuated disc 39 to rotate from one notch to another, during which time a circuit is closed at 40 to energize a magnet 41 which opens a valve 42, a stream of paint from a tank 43 being thereby projected on to the track. The valve 42 may actuate a style to record its operations on the moving band of the stylograph 26 or on a separate moving band. By connecting another Bowden cable to the bogie, and its sheath to the vehicle body, the positions of the curves along the track may be recorded on one of the moving bands, both of which are suitably calibrated by contact devices operated from one of the driven wheels.

Title: Arithmetic circuitry
IPC: G06F7/495
Filed: 1959-02-13
Abstract: 847,996. Digital electric calculating-machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 13, 1959 [Feb. 14, 1958], No. 5028/59. Drawings to Specification. Class 106 (1). A circuit for correcting the result of binary true or complement addition of binary coded decimal digits includes a register for simultaneously indicating the orders of the result, a first result line on which signals appear representing the result indicated by the register, a second result line on which signals appear representing a corrected result, and means for gating signals to output from either the first or second lines dependent on whether a decimal or binary carry occurs as the result of true or complement addition respectively. Digits are represented in the 1, 2, 4, 8 code, taking the B 1 , B 2'  B 4  and B 8  positions in a word. On true addition, if no decimal carry occurs the required result is that indicated in the register, if a decimal carry occurs the result is the indicated result less 10. In complement addition the 15's complement of the subtrahend is entered in the adder and a 1 is entered in B 1  time of the low order digit of the minuend and subtrahend. If there is a binary carry on complement add (carry from the B 8  position) the result is negative and the required result. If there is no carry it is necessary to convert the result to 10's complement form. A comparison of results indicated in the register and the corresponding required results for addition or complement addition of two binary coded decimal digits is made and it is noted that (1) B 1  in the register is always the same as B 1  of the desired result; (2) on true add without decimal carry or complement add with binary carry the B 2 , B 4  and B 8  bits in the register are those of the required result; (3) on true add with decimal carry or complement add without binary carry B 2  in the register is the complement of the required B 2 ; (4) B 4  is one in the required result if for true add with decimal carry the register contains (a) ones in B 2  and B 4  or (b) zeros in B 2 , B4 and B 8 , or if for complement add without binary carry in the register (a) B 2  is one, B 4  zero or (b) B 2  is zero, B 4  and B 8  one; (5) B 8  is one in the required result if for true add with decimal carry in the register B 2  is one, B 4  and B 8  are zero, or for complement add the register contains ones in B 2'  B 4  and B 8 . A conversion circuit is described based on these relationships using coincidence gates and operated by B 1 , B 2 , B 4  and B 8  timing signals and signals representative of true or complement add operations and binary or decimal carry or no carry conditions.

Title: Closure method and means for the ends of nuclear fuel rods having a very thin sheath
Inventor: ALFILLE LUCIEN
IPC: G21C3/10
Filed: 1965-02-05
Abstract: 1,085,382. Fuel elements. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Feb. 5, 1965 [Feb. 13, 1964], No. 5189/65. Heading G6C. The end of a flexible metal sheath into which nuclear fuel is inserted to constitute a fuel rod is closed by inserting the fuel in the sheath so that one end of the sheath extends beyond the corresponding end of the fuel, inserting in this end of the sheath a metal plug having a peripheral outwardly raised edge until the sheath projects beyond the edge of the plug, mounting a metal ferrule around the end of the sheath in correspondence with the edge of the plug, and heating the extending end of the sheath and the adjoining parts of the ferrule and plug so as to weld the sheath, ferrule and plug together. The thicknesses of the plug edge and the ferrule are substantially greater than that of the sheath whereby a portion of the welding heat is dissipated in the plug edge and the ferrule sufficient to prevent breakdown of the sheath. The thickness of the ferrule is preferably at least as great as that of the plug edge. The method of closure is described with particular reference to the fuel rod of Specification 978,737 which has a stainless steel sheath of thickness less than 0À1 mm. Several embodiments are described and in that shown in Fig. 5, in order to provide axial locking of a steel sheath 1 between a plug 7 and a ferrule 10, both also of steel, the upturned edge 9 of the plug comprises a flange 15 joined to the edge 9 by a curved junction 16 to allow inward folding of the sheath 1 by plastic deformation, and the ferrule 10 comprises an upper flange 17<SP>1</SP> locking the folded end of the sheath 1. The right-hand side of the Figure shows the assembly before welding, the arrow 11 indicating the direction in which the welding device is pointed, while the lefthand side shows the completed fuel rod with the sheath 1, the plug 7 and the ferrule 10 being joined by a weld 12. The ends of the plug 7 and ferrule 10 opposite to the weld 12 are rounded so as to prevent the sheath 1 from being cut or broken during swelling or contraction of the latter. The application of the invention to the closure of a sheath for which the use of a massive plug 18, through which thermocouples may extend, for instance, makes it necessary to resort to lateral welding of the sheath to a turned edge formed by a lateral flange 19 is shown in Fig. 6. The flange 19 is provided with a curved junction with the plug body such as to allow flaring of the sheath 1, ferrule 10 also having a curved edge corresponding to that of the flange 19 and, outwardly thereof, having a chamfered edge 20 adapted for the reception of the melt forming the weld 12.

Abstract: 1,038,141. Valves. CARBONARO M.C. Feb. 8, 1963 [Feb. 10, 1962], No. 5249/63. Heading F2V. [Also in Division F4] A thermal valve for controlling the gas flow to a burner comprises a diaphragm 26 adapted to close a gas orifice 28 and urged to an open position by a spring 27. A rod 29 is urged against the diaphragm by a bimetal strip 16 adapted to be heated by two resistances disposed in grooves in a steatite element 15 to open the valve and connected to the burner control circuit. The action of the bimetallic strip is adjusted by a screw 34, screwed into the strip and abutting the end of the rod. If the current fails the rod can be displaced to open the valve by pushing inwardly a plate 32. The plate remains in this position because the bimetal strip 16 applies the plate against the sides of guide slots in the valve casing. When the current returns the valve is held open by the heated bimetal strip and the plate is returned by a spring 33.
