Title: Improvements in the catalytic cracking of hydrocarbons
IPC: C10G11/18
Filed: 1945-03-29
Abstract: <PICT:0589847/III/1> Gasoline of low acid heat is produced by passing heavy hydrocarbon oil vapours into a zone through which hot cracking catalyst is circulated, separating from the cracked products a fraction having an end boiling point not higher than 400 DEG F, and containing only C5 and higher hydrocarbons, and recycling a portion of this fraction to the cracking zone.  Gas oil, fed through line 15, is mixed in line 12 with a suspension of hot regenerated catalyst in the recycle fraction, and the mixture is introduced into reaction vessel 10 at such velocity that a dense phase with an upper level at 26 forms therein.  The amount of recycle fraction in the mixture may vary from 10 per cent. to 60 per cent. of the fresh feed.  The reaction products are withdrawn through separator 34 and line 38 and passed to fractionating column 42 from which various fractions are removed.  The lightest constituents, from the head of the column, are condensed in condenser 113 and passed to gas separator 114 from the top of which C4 and lighter gases are withdrawn through line 115 while, from the bottom, is withdrawn a C5-300 DEG F or a C5-400 DEG F gasoline.  A portion of this gasoline is pumped through line 28 for use as the recycle fraction, hot regenerated catalyst from regenerator 62 being added to it from standpipe 14 before it is mixed with fresh gas oil and re-introduced into the reaction vessel 10. The remainder of the gasoline is withdrawn from the system through line 136.  A slurry of catalyst in heavy cracked oil is removed from the scrubbing section 41 of tower 42 and is withdrawn from the system via line 122, or admixed with fresh feed in line 15. In a modified method of operating, the fresh feed is introduced through line 13.

Title: Method and system for determining aboard an airplane its position  with respect to an airport landing strip
IPC: G01S5/14
Filed: 1974-02-22
Abstract: 1444046 Aircraft position determining system ELECTRONIQUE MARCEL DASSAULT 22 Feb 1974 [26 Feb 1973] 8111/74 Heading H4D The Specification describes a method and system for determining the position of an aircraft approaching an airport runway P, which comprises, a plurality of beacons 12, 14, 16, positioned at fixed known positions relative to the runway, a central airport transmitting station which generates measurement pulses produced by an atomic clock and enables individual beacons in a predetermined order to transmit a measurement pulse and information corresponding to its altitude. The aircraft has aboard a receiving and computing system linked to a less accurate clock, and a memory, storing the position of the beacons, which operate so that the aircraft's position is ascertained by processing a plurality of received measurement pulses, each representing the aircraft's distance from a particular beacon, so that the aircraft clock is brought progressively into synchronism with the airport clock thereby allowing the aircraft's space and time co-ordinates to be computed. Provision is made in the computing system to take account of the aircraft's speed and heading. The ground equipment includes the atomic clock which is linked to a master transmitter which first transmits a pulse code, e.g. a 3  in Fig. 4 which enables one particular beacon, and at a particular carrier frequency. The beacon then converts the master transmitter carrier frequency, e.g. from 1À5 GHz to 1À7 GHz, and retransmits a measurement pulse, e.g. c 3  received from the master transmitter after the pulse code enabling the beacon. The measurement pulse C 3  may be preceded, for each beacon by a pulse code b 3  corresponding to that beacon's altitude so that the aircraft computer may make the necessary adjustment. The master transmitter may have provision for monitoring the transmission from each beacon to check on the accuracy of the time measurement pulse transmitted. The aircraft receiver, tuned to the beacon frequency, e.g. 1À7 GHz, receives the information in a computer 52 (Fig. 5), which also receives from memory 54 the co-ordinates of the transmitting beacon, and from a system 56, the aircraft's estimated position Œ500 m. The computer estimates the position of the beacon, and includes the transmitted altitude information at input 51. The time of reception of the measurement pulse is compared with the time of occurrence of the aircraft clock pulse, and the time scale of the aircraft's internal clock is progressively brought, on successive receptions of measurement pulses, into synchronism with the ground based atomic clock, using recursive filtering techniques in computer 52. Provision is made, in the absence of a beacon in a particular position, for the measurement to be skipped until the next measurement pulse, or if a beacon is in a position other than that stored in the aircraft memory, for that beacon to transmit along with the information in pulse, e.g. b 3 , its actual co-ordinates.

Title: Improvements in automatic or semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1925-03-30
Abstract: 255,917. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), and Wright, E. P. G. March 30, 1925. Automatic exchange systems.-The earlier outlets of subscribers' line switches lead direct to selector trunks, while the later outlets give access over secondary switches to a separate group of selector trunks which are only brought into use at peak periods. The secondary switches may be of the pre-selecting type, or may be arranged to pro-select a trunk only if the next secondary switch on either hand is engaged. Pre-selective hunting is prevented if all the outlets of the division to which the switch belongs are busy, and the switches are marked busy by a connection from the test wiper to the incoming test circuit. When an outlet falls free a series of starting relays operate in succession to start different subdivisions of the switches on their pre-selective hunt. The chain of starting relays is common to several division of secondary switches, each relay controlling the starting of one or more switches in each division. When the secondary switch shown in Fig. 3 is seized, relay A is energized in a circuit over the subscriber's loop from battery and ground on the a and b wipers, locks itself through the wiper PI to ground at the switch ahead, and grounds the wiper P2, the terminals of which are multiplied but have no other connections. When the connection is released, relay B which till then was short-circuited at PI becomes energized in series with relay A. Relay B de-energizes relay A, energizes magnet R to step the switch to its next terminals, and relapses. If either of the relay Ax, Ay is energized (these being the A relays of the next switches on either hand) a circuit is prepared for relay B to the wiper P2, so that if the wiper is on a busy trunk the relay B is energized again and the switch steps on. When all the outlets from a division are busy a chain circuit energizes relays GB3R, GB4R which open the circuits of magnets R to prevent hunting. When an outlet falls free a circuit is momentarily closed by the relays GB3R, GB4R to energize a series of starting relays SR1 - - SR3, Fig. 4, each of which closes a holding circuit to the next, so that after ener. gizing simultaneously they fall off in succession. The starting relays, through their armatures 10, control the connection of battery to the B relays, Fig. 3, so that the sub-divisions of secondary switches are successively enabled to start hunting as the corresponding SR relays relapse.

[Classes 72 and 82 (i)] In the production of steel at suitable casting temperature from molten steel obtained in a converter, the steel is first de-phosphorized either in the converter if it is a basic converter or in a ladle if the converter is either acid or basic, transferred to a basic converter not substantially contaminated by phosphorus containing slag and whose lining is not substantially impregnated with such slag and then acted upon in the basic converter with such a quantity of a reducing agent, the oxide of which has a high heat of formation, e.g. silicon, that by blowing for a very short time, e.g. 15 seconds to 1 minute, the combustion of the reducing agent evolves a quantity of heat which is sufficient to bring the steel to the high temperature necessary for casting either directly or after a subsequent de-oxidation. Manganese may be added before the short blowing which is effected in the presence of a slag rich in alumina and in alkaline earth and/or alkaline bases used in such quantity that after the blowing it is still basic. If excess of the reducing agent is added to the steel, the balance is incorporated in the steel. Alloying ingredients, such as chromium, nickel, molybdenum or vanadium may be introduced into the converter during the short blowing either in metallic form or in the form of oxidic compounds which are placed in the slag and reduced by the reducing agent. Specifications 404,300, 521,254 and 533,671 are referred to.
