Title: Improvements in and relating to Vaporizing Hydrocarbons and Producing Hydrocarbons having Low Boiling Points from Hydrocarbons having High Boiling Points.
Inventor: DAY DAVID TALBOT
IPC: C10G9/00
Filed: 1917-11-16
Abstract: 119,440. Day, D. T., and Day, R. B. Sept. 28, 1917, [Convention date]. Hydrocarbons, distilling and cracking; bulk evaporators; spray evaporators. - Hydrocarbon oils are vaporized by causing hot products ot combustion free from oxygen to bubble through them. The process is used for removing gasoline from oils that are subsequently to be cracked by spraying into hot products of combustion under pressure as described in Specification 113,264. Hot gases formed by combustion in a chamber 1 are led by a conduit 8 into a cracking-chamber 10 into which oil is sprayed by a nozzle 11. The hot gases, together with the products formed by cracking at a temperature of at least 360‹ C., are led by a pipe 15 to a perforated pipe in the base of the vaporizing-chamber 16. The gases after bubbling through the oil are led, together with the gasoline formed by vaporization, by a pipe 19 to a fractionating-tower 20 maintained at least 190‹ C. The low-boiling hydrocarbons that escape condensation are led by a pipe 23 to a condenser. The crude oil under treatment enters the fractionating-tower 20 by a pipe 22 and trickles downwards. The oil thus heated, together with products formed by condensation, flows through a pipe 21 to the vaporizing-chamber 16. The oil after it has been freed from gasoline in the vaporizing-chamber, is pumped through a pipe 17 to the spraying-nozzle 11.

Title: A method of or apparatus for electrical load dispatching in an alternating current power distribution system
IPC: H02J3/06
Filed: 1958-05-27
Abstract: 858,608. Parallel operation of alternators. SHIPLEY, R. B. May 27, 1958, No. 16908/58. Class 38 (4). An alternating current power distribution system is arranged for economic load sharing between a plurality of generators, which are interconnected to the load through a transmission network having appreciable power losses, by choosing one of the generators as a reference and bringing each of the other generators into economic balance therewith, such balance being attained when each of the other generators is set to render a matrix quantity substantially zero, the quantity being expressed in the Specification by a complex mathematical formula. In Fig. 1 are shown two generators 10, 18 supplying a load 15, the interconnecting network being shown as comprising resistors 11, 13, 16 and reactors 10, 14, 17, whilst the generator 10 is chosen as a reference. Current transformers 19, 20 are included in the network connections to the generators 10, 18, respectively, with resistors 21, 22 connected across the secondary windings of the current transformers. The voltages appearing across resistors 21, 22 are connected in series aiding relationship and subtracted from the terminal voltage of the generator 10, the resultant voltage being applied to a potential transformer 23, the transformation ratio of which represents the incremental generating cost of generator 18. Thus the voltage appearing across the secondary winding of transformer 23 represents a voltage multiplied by the incremental generating cost for generator 18 whilst in similar manner the voltage on the secondary winding of transformer 24 represents the reference voltage of generator 10 multiplied by its incremental generating cost. The outputs from the secondary windings of transformers 23, 24 are subtracted and the resultant voltage applied to terminals 26 of a null-reading instrument 25 to the other terminals 27 of which is applied the reference voltage of the generator 10. Economic balance is achieved when the instrument 25 gives a null reading; with any other reading an attendant is required to operate the throttle control of generator 18 until a null reading is secured on instrument 25. A null reading is given when the formula referred to earlier is satisfied. In this embodiment all the elements 10 to 18 are actual parts of the power distribution system. In a further embodiment is shown a system wherein minimum use of actual parts of the power distribution system are used, certain of the components being simulated by electrical quantities.

Title: Improvements in Electrically Operated Overhead Lifting Gear.
Inventor: VAUGHAN WILLIAM HENRY
IPC: B66B5/08
Filed: 1917-11-17
Abstract: 117,019. Vaughan, W. H., and Wood, F. Nov. 17, 1917. Overwinding and overrunning, preventing.-An electrically-operated overhead lifting-gear is provided with a device actuated by the lifting rope for stopping the winding drum at any desired point of the raising or lowering operation. The winding drum a and related parts are shown in front elevation in Fig. 3, in plan in Fig. 4, and in side elevation in Fig. 5. A guide d, Fig. 4, has a projection d<1> engaging with the rope groove of the winding drum a and has also a rope-guiding slot d<2>. The guide slides on a bar d' and carries a roller c engaging in a slot in a bar f connected at one end to a multiplying lever g pivoted to a bracket at its upper end and to a sliding plate h at its lower end. The sliding plate has an approximately central aperture through which passes a pin i on the brake-operating cam i<1>, the arrangement forming a lost-motion connexion allowing the sliding plate at the ends of its travel to rotate the cam i<1> from the operative position shown in Fig. 3, in which the brake straps k<3> are not in contact with the brake drum k<1>, to the inoperative vertical position in which the spring-pressed brake straps engage the brake drum and, as the cam i' is mounted on the controller-operating shaft j, to put the controller n simultaneously into the off position. The slot in the bar f is so dimensioned that when the roller c of the rope-guide reaches the left-hand end of the slot. the mechanism stops the controller and applies the brake at the desired point in the winding operation. A similar .action takes place during unwinding except that movement of the roller e towards the right can be varied by altering the position of the adjusting set-screw p and so varying the limit of the unwinding operation.

IPC: G01V3/10
Filed: 1957-05-29
Abstract: 860,197. Electric tests. RANK CINTEL Ltd. May 29, 1958 [May 29, 1957], No. 17031/57. Drawings to Specification. Class 37. In known systems for detecting magnetic or electrically conductive bodies, the coupling between coils connected to an amplifier input and output respectively is varied by the presence of the body so that the circuit oscillates. In order to distinguish between different bodies which cause the circuit to oscillate at frequencies which differ only slightly, the oscillator output is caused to beat with the output from a separate oscillator, the frequency of which is of the same order so that the difference frequency which may be in the audible range enables objects to be distinguished. Earphones may be used and a filter circuit may be connected between the mixer output and the indicator device or between the oscillator output and the mixer to assist in separating a desired signal. The input coil is shunted by a tuning condenser and the output coil may be shunted also so that it is resonant at the same frequency as the input.

Title: Improvements in or relating to the treatment of sewage and other waste liquors
IPC: C02F3/12
Filed: 1950-07-11
Abstract: 688,650. Treating sewage. KESSENER, H. J. N. H. June 15, 1951 [July 11, 1950], No. 17277/50. Class 111 In the purification of sewage and other waste liquors by activated sludge and aerating means which includes the step of causing a circulation cf the sewage a controlled portion of the already more or less purified sewage, before the portion has been settled and whilst it is being aerated, is added to less or still less purified sewage whilst the passage of sewage directly in the other direction is prevented. Sewage enters a tank 1 through inlets 5, Fig. 2, encounters sludge flowing in at 8 and flows through an opening 9 in a wall 3 to a second tank 2 which it leaves by a weir 6 and outflow channel 7. Rotary surface aerators 10, 11, preferably as disclosed in Specification 445,352, are provided, one in each tank, Fig. 3, and are mounted in bearings 15, Fig. 2. The aerator 11 in tank 2, Fig. 3, projects liquid from that tank as a spray through openings 16 provided in the separating wall 3 above the common liquid level 17. Less pure liquid similarly sprayed by the aerator 10 in tank 1 towards tank 2 is prevented from passing through the openings 16 by plates 18, Figs. 2 and 3, one being opposite each opening and adjustably spaced from it by mechanism 20, 22, to 24. The spacing is adjusted to control (or prevent, when the plate is in contact with the wall), the amount of sewage being fed through the opening 16. In Fig. 4 each aperture 27 extends into the liquid and has connected with it a trough 32 with closed ends the mouth of the trough being located in, and wholly above the liquid level in, the tank 1. Transfer of sewage is effected by the aerator 35 and is controlled as to amount by an adjustable weir 37. In a further modification (not shown) the trough has its mouth above the liquid level in tank 2 instead of in tank 1, the adjustable weir is on the right of the wall 3, and the aerator in tank 2 is to the right of the trough and sprays sewage into it.
