Title: Process for cracking hydrocarbon oils
Filed: 1927-04-29
Abstract: 284,507. Dubbs, C. P. April 29, 1927. Hydrocarbons, cracking. - In a process for cracking hydrocarbon oils, in which the oils are heated under pressure to cracking temperature in the pipes 7 of a furnace 8 and are then passed into a reaction chamber 11 under reduced pressure, the vapours produced being passed through a dephlegmator 2 and condenser 17 to a collection chamber 18, the incondensable gases produced in the reaction are led from the chamber 18 through tubes 28 in a separate furnace 29 where they are superheated substantially above the temperature in the furnace 8 and then injected through a pipe 35 into the liquid in the reaction chamber 11. The crude oil is passed from a pipe 1 through the dephlegmator 2 to condense the heavier reaction products and the mixture obtained is forced into the tubes 7 by a pump 5. The incondensable gases may be obtained from an outside source and the supply to the tubes 28 may be regulated by adjustment of a valve 26<a> on a bye pass 26. The oils are preferably heated to about 850‹ F. in the cracking zone under a pressure of 300 lbs. per square inch while the incondensable gases are heated to 1200-1500‹ F. Specification 249,604 is referred to.

Title: Improvements in or relating to the manufacture of slivers, rovings and yarns of staple fibres
IPC: D01G1/08
Filed: 1947-04-30
Abstract: 632,697. Making slivers, rovings and yarns of stapled fibres. POOL, W., and McGILL, A. April 30, 1947, No. 11620. [Classes 120 (i), 120 (ii) and 120 (iii)] A process for the conversion of a bundle of continuous filaments into a continuous product made of staple fibres comprises gripping the filaments of the bundle at two spaced points, forwarding the gripped filaments from the first of said points towards the second at one linear speed and from the second point onwards at a greater linear speed so as to stretch the filaments between the two points, and at a third point, between the two points subjecting the filaments to sharp and rapidly repeated impact so as to break, at said third point, some of the filaments that have been stretched to a degree substantially short of that at which they would break under tension. Slivers 1 from cans 3 are led to flattening bars 7 and thence between tensioning roller sets 8, 9, 10. Between roller pairs 12, 13, 19, 20, which may include leather &c. belts 16, 21, the flattened sliver is subjected to a " draft of 5 or more and while tensioned below its breaking point, is subjected to impact by a straight edge 26 vibrating at 2,000 oscillations or more per min. The impacts break the filaments of the sliver and form a continuous stapled product which is subject to a false twisting device at 30 and lubrication at 31. After passing through a further false twisting device 38 and a "stuffing- box," the crimped sliver is collected in a rotating coiler can 44. In a modification, the stapled sliver is fed by rollers from the false twister direct to a flyer for winding it on a bobbin as a roving. In a further modification, the stapled product is fed direct to a ring spinner for winding on a bobbin as a coarse yarn. Specification 582,949 is referred to.

Abstract: 610,777. Copying and carving stone. JAQUES, J. M., and GILDERSLEVE, C. April 16, 1946, No. 11679. [Classes 124 and 145 (i)] A multiple carving machine comprises a series of rotatable cutters or carving tools 4, and a tracing stylus 8, mounted on a fixed support, and a work-piece carrier 18 rotatably mounted on supporting means adjustable for moving the carrier 18 relatively to the cutters into and out of carving position, and to permit the carrier to be rotated to present either of oppositely disposed faces of the work-pieces b to the cutters for carving. Work-pieces b and a pattern a are carried by holders 21, mounted on the carrier 18 which is rotatably mounted in arms 15 by stub shafts 19, which allow the carrier 18 to move axially against a spring 20. The arms 15 are pivotally mounted at 16 on side plates 10 pivoted at 11 to uprights 2. The work is brought into the carving position by raising the arms 15 against a spring 17 by means of a handle 30, the side plates 10 being depressed if necessary against a spring 13 and the sliding and pivoting movements of the carrier 18 in the arms 15 allow the cutters to travel over one face of the work under the control of the stylus 8. The carrier 18 may now be rotated in the arms 15 through 180 degrees to bring the opposite faces of the work-pieces into the carving position. The work holders are rotatably mounted in the carrier 18, and after a pair of opposite sides have been carved as described above, the holders are turned through 90 degrees and the carving operations repeated.

A starting and operating circuit for a gaseous discharge lamp with preheating of the electrodes 6, 7 controlled by a glow thermal relay tube 13 consists of a series circuit from the domestic supply through an inductance 10 and capacitator 9, through the electrode 6, the relay 13 and electrode 7 back to the supply: This circuit gives a leading power factor and according to the invention a saturable reactor 14 is' connected in parallel with the lamp, and its constant in association with those of 9 and 10 are so chosen that during the starting period with the relay 13 open it becomes saturated and its inductance,falls to a low value ; a high peak voltage is developed across it sufficient to produce a glow discharge in the relay 13 and cause its closure. The resulting drop of voltage across 14 causes the glow discharge to cease . and when the relay cools down, while the electrodes are being heated, it opens giving the necessary " kick " to start the discharge and leaving the reactance in circuit at a high value in its unsaturated state. An additional lamp in a circuit with a lagging power-factor may be connected between the electrode 6 and the full winding of a high-leakage auto-transformer.

Title: Improvements relating to electrical crossover filters

Abstract: 734,346. Transformers. TANNOY, Ltd., and CROWHURST, N. H. Nov. 11, 1953 [Aug. 15, 1952], No. 12323/52. Class 38 (2). [Also in Group XL (b)] An audio frequency transformer for separating the high and low frequencies on either side of the cross-over frequency comprises a primary winding 1 tightly coupled with a first secondary winding 4 and loosely coupled with a second secondary winding 5, this second secondary winding 5 in turn being tightly coupled to a tertiary winding 6 across which is connected a condenser C. Low frequencies are developed by the second secondary winding 5 at the terminals L, F for supply to one loud-speaker unit, the high frequencies being developed across the two secondary windings 4, 5 oppositely connected in series, so far as frequencies below the cross-over frequency are concerned, at the terminals H, F for supply to a second loud-speaker unit. The loose coupling between the two pairs of windings 1, 4 and 5, 6 introduces leakage inductance and this inductance value together with the capacitance of the condenser C determines the cross-over frequency. Thus, by providing the tertiary winding 6 with tappings the cross-over frequency can be adjusted. In such a case however, the primary and secondary windings are also provided with tappings in order to allow impedance matching with change of cross-over frequency. The tappings may be logarithmically arranged to have the same ratio as the cross-over frequencies. When the windings are tapped the sections between different tappings may be of different size conductors. To effect the tight couplings the windings may be in two sections arranged one about the other and a magnetic shunt between the two pairs of windings may effect the magnetic leakage.

Abstract: 323,699. Field, M. B. April 20, 1929. Magnetic compasses.-In a quick acting, dead beat, liquid magnetic compass an annular card, of small diameter in relation to the diameter of the bowl, is supported by wires which are extended to bear damping blades operating in the liquid surrounding the card. These wires are bent downwards to clear a lubber wire attached to the bowl and the damping blades are generally about midway between the card and the bowl. The cover consists of a plano convex lens inclined to the horizontal. The annulus 1 is supported by wires 4 projecting radially outwards from the pivot carrying dome 5 and carrying the damping blades 3 which can be of other shapes besides that shown. The magnets 2 are circularly bent forming in effect interrupted rings with N and S poles at opposite ends of a diameter. The bends in the wires clear the lubber wire 7.
