Abstract: 1,272,770. Removal of sulphur oxides from gas streams. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 5 Aug., 1969 [7 Aug., 1968], No. 37701/68. Heading C1A. Sulphur oxides, i.e. sulphur trioxide and sulphur dioxide are removed from gases containing them by contacting such gases, in the presence of free oxygen with a melt at a temp. above 150‹ C. said melt consisting of one or more ammonium borates and/or ammonium phosphates containing a minor amount, e.g. so the melt contains 0À01 to 15% by wt. of metal, of one or more metal compounds which are soluble in the melt and which promote the oxidation of the sulphur oxides the molar ratio of H 2 O/(B 2 O 3 +P 2 O 5 ) of the melt being less than 3 and the molar ratio NH 3 /(B 2 O 3 +P 2 O 5 ) being greater than 0À5, The preferred metal content is 2-8% by weight of the melt. Metals exemplified are those in the following groups of the Periodic Table according to the " Handbook of Chemistry and Physics 1964", Ib, Vb, VIb, VIIb, VIII and the rare earth metals of Group IIIb and Tl. The metal may be added to the melt as an oxide, hydroxide, carbonate, nitrate, phosphite, sulphate borate, selenate, or aluminate. Before being subject to the sulphur oxide containing gas the melt may be pretreated with H 2  and/or CO. Preferably the molar ratio B 2 O 3 /P 2 O 5  in the melt is less than 1, e.g. less than 0À15. The molar ratio H 2 O/(B 2 O 3 +P 2 O 5 ) in the melt is preferably in the range from 1À5 to 2À7 and the molar ratio NH 3 /(B 2 O 3  + P 2 O 5 ) in the range from 1 to 3. Preferred metals added are copper, nickel, and didymium (defined as a mix of rare earths containing mainly La, Nd, and smaller quantities Pr and Sm) and they may be present in the melt in an atomic ratio Cu : Ni : Di = 1 : 1 : 0À1 up to a total content of 5% by wt. The oxygen required for the process may be present in the gas or the melt or may be added, e.g. in a volume ratio O 2 /SO 2  in the range 3 to 10, to the sulphur oxide containing gases. Iodine may be added to the melt as one or more covalent metal iodides, e.g. in an amount of 0À1 to 1% by weight of I 2  added as Ni, Co, Cu, Ag, Ce or Ti iodide. Various recipes for melts are given. The melt may be regenerated by treatment with COH 2  or mixture thereof, e.g. at 300‹ C. Alternatively the melt may be regenerated electrolytically using graphite electrodes. The melt may be supported on a carrier during the process and the carrier may be fluidized.

Title: Suspended railway system
IPC: B61C13/04
Filed: 1974-08-29
Abstract: 1479438 Elevated railways DEMAG AG 29 Aug 1974 [29 Aug 1973] 37775/74 Heading B7L In an elevated railway system comprising a trolley 2 having first and second wheels 6, 8 for engagement respectively with upwardly and downwardly facing surfaces of a rail 1, the spacing of the wheels is greater than that of the rail surfaces and the trolley has, or is adapted to have when loaded, its centre of gravity spaced longitudinally of the rail from the first wheel 6 such that the trolley tends to tilt about the axis of the wheel 6 to bring the second wheel 8 into engagement with the rail, the trolley being tiltable in the opposite direction to disengage the wheel 8 from the rail whereby the trolley may be displaced laterally of the rail to remove the trolley from the rail.  When the trolley is on a section of rail inclined as shown in Fig. 2 a line 20 through its centre of gravity is displaced towards a line 19 passing through the first wheel 6 as compared to the position of line 20 when the trolley is on a horizontal section of rail as in Fig. 1. If the rail inclination increases above that shown in Fig. 2 the line 20 may pass to the same side of line 19 as the wheel 8 so that the latter is caused to tilt out of engagement with the rail and for this reason a further wheel 8a may be provided to contact the rail when such tilting occurs. The wheel 8a is readily removable so as not to prevent the tilting process necessary to remove the trolley from the rail. When the trolley is on a section of rail inclined oppositely to that in Fig. 2 the spacing between lines 19 and 20 always increases above that in Fig. 1 whatever the rail inclination and thus the wheel 8 will always engage the rail. The trolley may have a frame 3 formed with a yoke 3b carrying the wheels 6 and a yoke 3c carrying the wheel 8 and guide wheels 9. The frame may carry a plate 3e on which electrical collector contacts are mounted for engaging conductors 18 on the rail. A motor 16 drives the wheel 6 and is located on the frame such as to displace the centre of gravity of the trolley to one side of the line 19. A bracket 14, 15 suspended from the yoke 3c is provided with bores 15a for suspending loads from the trolley.

Abstract: 1,167,604. Sewing machines. BEJOSS Ltd. 16 Jan., 1968 [19 Jan., 1967; 17 Aug., 1967], Nos. 2856/67 and 37901/67. Heading DIG. A presser foot for use on an overedge sewing machine has means for mounting the presser foot on the machine for pivotal movement about a horizontal axis transverse to the length of the foot, a trailing end extending from said pivot means, and means mounting a first cutting member, having a cutting edge for co-operation with a second cutting member mounted for movement with the stitch feed mechanism, with said edge in overhanging relation adjacent a transverse edge provided on said trailing end. As shown a pin 4, laterally extending from the presser bar 3, is pivotally received between a semi-cylindrical recess 5 formed in the presser foot 1 and a plate 6 secured to the presser foot. The trailing end 9 of the latter carries a post 10 to which is pivoted a bar 11. A block 12 is adjustably secured to bar 11 by a.screw 13 and is formed in its lower surface with a recess in which is mounted a knife blade 14 and into which projects a tongue 15 on end 9. A leaf spring 16 bears on bar 11 to bias block 12 downwardly. Block 12 is adjusted to align blade 14 with a knife edge 24 on a bar 22 secured to the feed bar 18. The arrangement is thereby such that work passing under the presser foot raises block 12, and when the trailing edge of the block passes block 12 the latter drops, whereby edge 24, on the next ascent of the feed bar 18, cooperates with blade 14 to sever the stitch chain. In a modification leaf spring 16 is replaced by a compression spring. In a further modification the upper knife blade is mounted on a downwardly-biased leaf spring projecting rearwardly from end 9.

Abstract: 810,695. Curving; drawing; winding and reeling. COULTER & McKENZIE MACHINE CO. Inc. Dec. 12, 1956 [Jan. 16, 1956], No. 37919/56. Class 83 (4). In a die box to cast and position a wire as it is pulled therethrough, a body portion 10, Fig. 1, is rotatably mounted on a base 11 and carries a transverse rotatable shaft 24 so mounted that the axes of rotation of the shaft and the body are perpendicular to and intersect each other, a die member 27, through which the wire is pulled, being positioned in the shaft 24 at the intersection of the axes so that the die 27 is universally adjustable about its centre point by independent means for rotating the body 10 and the shaft 24, each of the adjusting means including a relatively long lever arm so that a large adjusting movement results in a small movement of the die. A worm 32, Fig. 2, adjustably attached to the base 11 and meshing with a gear sector 31 attached to the body 10 provides adjustment for the die about axis XX by rotating the body 10 about a shaft 23 which may be locked in position by tightening a splitcollar 13. A second worm 35 is adjustably attached to the body 10 and meshes with a gear sector 34 attached to the shaft 24 which carries the die 27 in a countersunk recess 26. Rotation of the worm 35 causes rotation of the shaft 24 thus giving adjustment of the die 27 about the YY axis. Adjustment for wear on the gear teeth is effected by pivoting the journal brackets 41 and 36 of the worms about pins 42 and 37 respectively by rotating eccentric sleeves 43 and 39 in slotted holes. Wire to be drawn or guided enters the die box through an inlet opening 18, passes through the die member 27, which may draw, cast and position or only cast and position it, and leaves the box through the conical exit opening 20 to be wound about a drawing block or capstan. Back tension to effect the cast in the wire is provided by a tensioning roller when a drawing die is not in use.

Abstract: 1277219 Vehicle headlamps ROBERT BOSCH GmbH 29 July 1969 [30 July 1968] 37989/69 Heading F4R In a motor-vehicle headlamp for producing an asymmetric dipped beam comprising a parabolic reflector 1, a halogen bulb 10 situated with its filament located in front of the principal focus F of the reflector and a mask or hood 8 surrounding part of the bulb to define the form of the beam radiated by the headlamp, those parts of the mask which define the upper boundary of the beam, viz. its side edges 9, fit tightly against the envelope of the bulb 10 while the remainder of the mask is spaced from the envelope in order to allow cooling air to flow between the mask and the envelope. As can be seen from Fig. 1 an aperture 12 is cut in the lower part of the mask to permit increased flow of cooling air. A screen 14 preventing direct emission of light is attached to a bracket 15 extending from the mask. Light passing through the aperture 12 and reflected upwards from the reflector 1 is refracted back in a downward direction by means of prismatic ribs 13 in the lower half of the front lens 2. To prevent light refracted upwards by the short stepped portions of the ribs 13 from causing dazzle, these stepped portions are shaped so as to cause an additional sideways deflection of the light. The bulb-holder incorporating the mask 8 is made of aluminium to provide good heat conduction and has a blackened cooling cylinder 19 attached to its rear by a clamp 18.

[Also in Group XXXVI] A variable quantity produces a change in a capacitance which forms part of a tuned circuit coupled to another tuned circuit having the same resonant frequency; one of the circuits forms a generator of oscillations which are fed to the other circuit and the phase difference between the voltages across the two circuits is measured. In Fig. 1 the generator 4 passes signals via the condenser 6 to the tuned circuit 2 normally resonant to the signals so that voltages 90 degrees apart in phase are applied to the first and third grids of the valve. Variation of the quantity to be measured (e.g. pressure, displacement) changes the capacitance 1 so that the circuit 2 is no longer resonant to the signals and the phase of the voltage across it changes. The anode current of the valve is then altered and the anode voltage is registered at 5 which may be e.g. a cathode-ray oscilloscope. In a modification (Fig. 2, not shown) the variable capacitance 1 is connected across the generator 4 instead of across the circuit 2, and thus varies the operating frequency.
