Abstract: 1419848 Production of chlorinated or sulphochlorinated alkanes BADISCHE ANILIN- & SODA-FABRIK AG 11 April 1973 [12 April 1972] 17365/73 Heading C2C Chloro and/or sulphochlorinated alkanes with more than 5 carbon atoms are prepared by passing the alkane in the liquid phase at a rate of 0À1 to 30 K per hour per litre of reaction space upwardly through a reaction zone whose longitudinal axis forms an angle of from 1À5 to 70 degrees with the horizontal, co-currently with the chlorine, or chlorine and sulphur dioxide, which are passed at a rate of 0À1 to 20 K per hour per litre of reaction space with a velocity of the gas layer of from 2 to 30 metres per second and a residence time of the gas layer in the reaction zone of from 2 seconds to one minute. For the production of monosubstituted alkanes, less than the stoichiometric amount of chlorine and a ratio of 0À5 to 0À9 mole of chlorine per mole of sulphur dioxide (in the case of sulphochlorinated alkanes) may be used. For the production of multisubstituted alkanes, 105 to 120% by weight of chlorine per mole of alkane and 110 to 170% by weight of sulphur dioxide per mole of alkane may be used. A reaction temperature within the range of 20 to 160 C. may be used but where simultaneous chlorination and sulphochlorination is conducted, the range may be 60 to 120 C. The gas pressure may range from 1 to 4 atmospheres. The process may be carried out in an inert organic solvent and under light irradiation, e.g. sunlight, mercury vapour lamps or fluorescent tubes. The reaction may be performed in a tube of length 10 to 100 metres and internal diameter 0À01 to 0À10 metre. The products may be used as pesticides, plasticizers or solvents.

Title: Improvements relating to variable electrical delay lines
IPC: H03H7/34
Filed: 1964-04-27
Abstract: 1,066,596. Variable delay lines. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. April 27, 1964 [April 25, 1963], No. 17380/64. Heading H3U. A variable delay line comprises a coil wound on an axis, and a conductor extending axially thereof but angularly adjustable about an axis offset from the axis of the coil although parallel thereto; the distance of the conductor from the coil can thus be altered to vary the capacitance of the delay line. In Fig. 1 the coil 2 is wound on a former 1 which carries an axial strip of conducting material 8. An insulated support 6 carries a similar conductive strip 7 whose distance from the strip 8 can be altered by rotating the support 6. The members 1 and 6 can be glass or paper tubes carrying thin metal sheets, which are preferably divided into axially parallel strips to reduce eddy current losses. The member 6 can be outside the coil. The absolute delay time can be reduced by omitting the conductive material 8. Additional variation can be obtained by axial movement of the member 6 if the strip 7 does not extend the full length of the coil. The eccentricity of the member 6 can be produced by the insertion of a strip of foam rubber on one side (Fig. 3, not shown). In use, the line is fed from a generator through a, resistance equal to its characteristic impedance, and similarly terminated at its far end (Fig. 2, not shown). For use in the line circuits of a PAL colour television receiver, the line is connected in series with a fixed delay line whose delay time is slightly less than that of one scanning line.

Abstract: 460,367. Making envelopes. SMITHE MACHINE CO., Inc., F. L. June 21, 1935, No. 17911. Convention date, July 13, 1934. [Class 94 (ii)] In a machine for making window envelopes, the blanks are delivered in a fanned-out pack with the overlapping bodies of the leading blanks free from contact with each other in the window areas and means are provided for engaging the leading margin of the foremost blank in advance of the leading margin of the second blank for pulling it clear of the blank. Envelope blanks 1, gummed on the sealing flaps, are delivered in overlapping relation by a drying conveyer 11 to an extensible table 8, with two adjustable portions situated above the level of the table 16. The feed rolls 14, 15 and sectors 22 operate upon the blanks, which sag under gravity in the space therebetween, to separate them so that the window edge of the one blank shall not catch upon the edge of the window of the following blank. A resilient tongue 23a extending through the window openings of the blanks may be fitted to aid separation. The blanks, now clear of each other, are advanced by pins 21 on a conveyer 20 and fed to belts 27, 28 where gum is applied around the window opening at 40, against a counter roller 44, and a window patch is affixed at 70, 70b. Patch material 50 from a reel 49 is severed by a cam-operated knife 55 in its passage past a block 54, the severed patch being sucked to an adjustable rotatable spring- urged sector 70 which presses the patch to the blank against a grooved counter roller 70b. The hollow shaft 71 of the patch applying sector. 70 is driven at variable speeds by the mechanism of Fig. 8 so that the sector may be at rest at the time the patch is severed by the knife 55 and moving at the speed of the blank during application of the patch thereto. In this Figure, the shaft 71 is driven through a toggle 94, 95 from a gear 92. The links 94, 95 of the toggle are pivoted to a pin 96 carrying a cam roller 97, influenced by a cam track 101, the position of which may be varied by slots 104 and clamping bolts 105, 106. In the event of no envelope blank being in position to receive a patch, the latter is sucked to the bed-cylinder 70b and carried away, being stripped therefrom by fingers 108 engaging grooves 109 therein. The envelope blanks are prevented from adhering to the cylinder 70b by a stripper 110. Belts 90 then re-align and convey the partly formed envelopes away for completion.

A belt conveyer 100, Fig. 3, for discharging cargo over the side of a ship at the end of the hatch-deck is fed by an elevator 93 from a belt conveyer 58 running along the hatchdeck. In the arrangement of Figs. 1, 3, the belt conveyer 58 receives material from a grab 56, Fig. 1, supported over a hatchway by a travelling bridge 4 as described in Specification 952,840. The conveyer 58 may be situated on the centre line of the ship between hatchways when each hold has two hatches side by side. The bucket elevator 93 discharges on to a reversible endless belt conveyer 96 via a hood 94 and a cross-feeder 95. Conveyer 96 feeds either of two overside belt conveyers located on opposite sides of the ship and supported on pivots 99 by booms 102S, 102P. In a second embodiment a conveyer 58, Fig. 6, mounted along one side of the hatches discharges into a boot 92 of a bucket elevator 93 which raises the cargo to an overside belt conveyer 100A via an apron belt conveyer 116. Conveyer 100A is pivotally mounted and supported by a samson post 120P and a boom 102P. A second conveyer 100B is attached to the first and supported by a post 120S and a boom 102S. The conveyers 100A, 100B are identical and either can be used alone. Fig. 9 illustrates an embodiment in which two reversible conveyers 58S, 58P extend lengthwise of the ship and may each comprise two reversible halves arranged end to end. Cargo is raised by bucket elevators 93S, 93P to overside conveyers 100. By providing appropriate conveyers 100 cargo can be discharged at either side both fore and aft.  In a further embodiment, cargo passes from a single conveyer 58, Fig. 12, up an elevator 130 and from there either directly to an overside conveyer 100, or through a removable by-pass trunk 137 to a second elevator 131 which feeds an overside conveyer on the opposite side of the ship. A similar arrangement may be used with two longitudinal conveyers sited one at each side of the ship, thus making possible the discharge of cargo at four points. Specification 952,840 is referred to.
