Title: Methods and apparatus for manufacturing telecommunication cables
Inventor: ASH BERNARD EDWIN
IPC: H01B13/02
Filed: 1962-03-27
Abstract: 939,674. Electric cables. STANDARD TELEPHONES & CABLES Ltd. March 27, 1962, No. 11630/62. Class 36. [Also in Group XXV] In a telecommunication cable comprising conductors grouped e.g. in pairs or quads, the groups are imparted different angles of lay by twisting each group randomly the amount of change in the angle of lay of each group being determined both by a random value selected from a range and the average twist already imparted to the group. Insulated wires 20, 21 are drawn from drums 2 and twisted together inside a hollow shaft 19 which is rotated by a motor (not shown). The twisted group is passed around a capstan 5 to a take up drum. The capstan drive assembly comprises a pilot motor 7 driven by a power pack 11 and a tachogenerator 13 driven by the capstan. The output from the tachogenerator 13 is in series with a control unit 15 comprising a random voltage generator 16 which has its output sampled at regular intervals by a gating circuit 17. A bias generator 18 is in series with the gating circuit 17. The tacho-generator 13 generates a voltage which is passed through a long-time-constant filter 14 which produces an average value for the period of time constant. This average voltage is therefore proportional to the average of all angles of lay which are produced within the period of time constant of the filter 14. The output from the filter 14 is in series with the bias generator 18 and the gating circuit 17 and is added to the output of the latter and applied to the power pack 11 which drives the motor 10 at randomly selected speed, which in turn changes the angle of lay at randomly selected rates for equal periods of time. Fig. 2 shows another control circuit producing the capstan driving voltage. A random voltage is produced by noise from a neon tube N. Switches S 1  and S 2  are opened and closed alternately with a period of e.g. 10 millisecs. and when closed the instantaneous random voltage is stored in a capacitor C, connected to the grid of a paraphase integrating valve 3. When the switches are opened as shown an output from V 3B  is produced, the rate of change of which is proportional to the deviation of the grid voltage. A fraction of the anode potential V 3A  is smoothed by resistors R 13 , R 14 , R 15  and R 16 , and capacitors C 3  and C 4  so that the potential across the capacitor C 3  is an average of the output voltage. This is combined in series with the voltage charge in capacitor C 1  and produces the output.

Patent GB-314621-A (GB)
Title: An improved sprag for motor vehicles and the like
IPC: F16D41/07
Filed: 1928-04-21
Abstract: 314,621. Miller, W., and Lamb, H. T. April 21, 1928. Locking by frictionaL detents. - A spragging device for motor vehicles and the like comprises a single-acting wedge co-operating with a ball or roller and a stop whereby in one direction of rotation the wedge is forced into frictional engagement with one of the clutch members. The drawings show a sprag combined with a freewheel clutch in connection with the transmission shaft of a motor vehicle. The sprag is of the kind described in Specification 309,372 and comprising a casing 1 secured to the gear-box and provided with a liner 2 with which engages a series of wedge-members 9 connected by springs 11 to stops 10 secured to the rotatable member 3. Rollers 7 are interposed in recesses in the member 3 between the wedges and a ring 8 freely rotatable on an inner part of the member 3. When the vehicle is driven in the forward direction and the member 3 in the opposite direction to that of the arrow, the stops 10 carry the wedges round and free rotation is permitted. If the vehicle tends to move in the reverse direction, the wedges assisted by the springs lag behind and the rollers engage the wedges. When it is desired to render the sprag inoperative, stops 5 slidably carried by the member 3 are thrown into position to engage the wedges and prevent them from lagging. The sides of the recesses for the rollers in the member 3 may be curved as shown or, if straight, may be lifted over to prevent the rollers from exerting pressure on the wedges by centrifugal action, this being undesirable during forward running. The sprag device may also take the form of any of the freewheel clutches described in Specification 310,564, [Class 80 (ii), Gearing, Variable-speed &c.], with the exception that the wedges are single-acting and abut at their wide ends against stops secured to the roller-container member while the narrow ends of the wedges abut against the sliding stops. The free-wheel clutch shown is of the kind shown in Figs. 1 and 2 of Specification 310,564, [Class 80 (ii), Gearing, Variable-speed &c.], the members 3 and 12 forming respectively the driving and driven members thereof. The sliding stops 5, 6 for the sprag and clutch are carried by a common sliding collar 4 operated by the rod and bridle 13, 14. Thus when the collar is moved to the left, the sprag is rendered inoperative and the free-wheel clutch becomes bi-directional so that the vehicle may be driven in reverse. This operation may be effected automatically when the gear lever is put into reverse position as described in Specification 310,564, [Class 80 (ii), Gearing,. Variable-speed &c.].

Patent GB-722930-A (GB)
Title: Improvements in or relating to the coking of heavy mineral oil products
IPC: C10B55/10
Filed: 1952-05-13
Abstract: Heavy oils such as crude, reduced crude, residuals, shale oil and tars are processed by cracking in the presence of a small amount of added coke under such conditions as to convert the oil into coke, distillable oil and gas, and passing the products of cracking to a fluidized solids bed maintained at a sufficiently high temperature to remove the distillable oils, the coke being retained in the bed.  The vapours may be fractionated to give the required range of products. Cracking is substantially complete before the products pass to the fluidized solids bed so that no additional cracking occurs in the bed which acts solely to separate the coke and distillable oils in the cracked products. In Fig. 1 feed from line 10 mixed with seed coke from line 16 is preheated at 12 and cracked in drum 14 for 2 to 240 minutes at 750-950 DEG F. and 100-3,000 p.s.i. pressure.  Steam or a low boiling oil diluent may be added to the feed through line 18. The products are fed via line 22 through a pressure reducing valve either to a spray <PICT:0722930/III/1> <PICT:0722930/III/2> <PICT:0722930/III/3> 38 above a fluidized solids bed in vessel 24 or to a pipe 44 submerged in the bed.  Distillable products pass overhead and are fractionated at 42.  Coke is retained in the bed, excess coke being withdrawn at 84.  Heat for the fluidized bed is obtained by partially burning some of the coke in heater 64, the heated coke being returned to the vessel 24.  Residuals from fractionator 42, containing carried-over coke from vessel 24 are preferably recycled to preheater 12.  In the apparatus of Fig. 2 the feed is cracked in a coil 112 immersed in the fluidized solids bed and terminating in a reducing valve 126 and nozzle 124 above the level of the dense phase.  Heat for the bed is obtained by feeding into the bed an oxidizing gas at 134 and partially burning the coke in situ.  In a similar apparatus Fig. 3 (not shown) heat for the bed is supplied indirectly by withdrawing some of the coke and passing it mixed with an oxidizing gas through a coil immersed in the lower part of the fluidized solids bed below the cracking coil.  In a further arrangement, Fig. 4, the feed is initially vacuum distilled in column 208 after being preheated in coil 204, residue from the distillation being cracked in coil 216, after addition of seed coke and if desired a light oil diluent via line 219.  The cracked products are fed to fluidized solids bed 226, vapours passing to column 208 where they assist distillation and are scrubbed by the feed from line 206, removing heavy products and carried-over coke.  The fluidized bed is heated in the same manner as in the apparatus of Fig. 3.

Abstract: 290,660. Jackson, L. Mellersh-, (Koppers Co.). April 27, 1928. [A Specification was laid' open to inspection under Sect. 91 of the Acts, May 21, 1928]. Materials for purifying; scrubbers and washers.- Hydrogen sulphide is removed from fuel gas by means of an ammoniacal liquid which is subsequently aerated in the presence of other catalyst consisting of a metallic compound, e.g. the oxide of hydroxide of iron, cobalt or nickel, in such amount as to promote the oxidation of sulphide to thiosulphate while avoiding the liberation of hydrogen sulphide or sulphur. The treatment is preferably effected prior to complete removal of ammonia from the gas, which passes through an absorber 1 in countercurrent with an ammoniacal suspension of metallic compound. Fouled liquid passes into an enclosed spray chamber 5 through which air or oxygencontaining gases are drawn by an exhauster 7, the chamber being filled with spray or fog by means of rapidly rotating cylinders 6 partially immersed in the liquid. The air which contains ammonia removed from the solution is conducted through a saturator 13 of known type, escaping through a conduit 17. Regenerated liquid is returned to the absorber 1. Concentration of am. monium thiosulphate in the liquid gradually rises and when it reaches a predetermined point a portion of liquid is passed through a filter press 25 for removal of catalyst and adventitious sulphur, to a reaction vessel 27 having a number of foraminous aerators 28 and steam coils 30 which heat the liquid to near boiling point, converting the ammonium thiosulphate to sulphate. Vapours containing sulphur dioxide are led through a conduit 32 to the spray chamber 5. The sludge produced by evaporation in the chamber 27 or a separate vessel may be forced by a pump 33 to the saturator 13.
