Skips; load, engaging.-In a blast furnace skip hoist the cover of the charging skip is provided with two flaps, which when open allow passage of the hoist pulley &c., but which are closed automatically as the skip is lowered on to the furnace mouth. The skip 14 is suspended by a rod 8 from a pulley block 15 of the hoisting mechanism, and during the charging operation is lifted from the ground level into a travelling framework 13 at the furnace top, which moves it horizontally into position over the furnace mouth. During the lifting of the skip, the cover 1 is supported within, but independently of, the framework 13, and the flaps 3 are held open to allow passage of the pulley block 15 by the engagement of arms 6 with cam surfaces 29. The skip is lifted until it passes between arms 12, which prevent lateral swing, and until it raises and supports the cover 1. When in position over the furnace mouth, the skip is lowered and the cover 1 descends with it, the arms 6 during the movement escaping from the vertical portions of the cam surfaces 29 and allowng the flaps 3 to close. To prevent accidental disengagement of the skip rod 8 from the carrier 16, a locking-device is provided consisting of a pivoted bolt 18 connected bv a link 25 to a crank-disk 20 carried by the pulley block. The bolt is operated by the arms 22, 23 which strike against the cover 1 during the raising and lowering of the skip.

Title: Improvements in road traffic control systems
IPC: G08G1/08
Filed: 1939-06-13
Abstract: 530,332. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and HERWALD, N. June 13, 1939, No. 17264. [Class 118 (ii)] In a vehicle-actuated system in which the right of way period granted to one traffic lane at an intersection may comprise two phases during the first of which right of way is given also to an opposing traffic lane, the second phase is introduced only in response to detectoroperation in the first lane after a demand has been registered by a further traffic lane. A system for controlling cross-roads, the phase conditions being indicated in Fig. 1, is described with reference to Fig. 2. (not shown) but certain relays appearing therein are referred to below for identification purposes. The invention may be applied also to the control at a T-junction. In phase 1, the A and D detectors both control the right-of-way extension relay RW, while the B and C detectors are connected to the same demand relay BD. Operation of the latter immediately connects the A detector to its individual demand relay AD, which, if operated before the speed timer relay, takes precedence over BD, and causes transfer to phase 2. The previous demand is stored by BD, and transfer to phase 3 occurs after any extensions due to the operation of RW, or after the maximum green period. In phase 3, the A and D detectors are connected to the same demand relay DD. If, on the other hand, AD is not operated, BD, is effective at once and phase 2 is cut off. In a similar way, phase 4 is introduced between phases 3 and 1 when a demand in lane A or D is followed by operation of the C detector. Specifications 408,706, 427,832 and 509,695 are referred to.

Title: Improvements in the refining of hydrocarbon oils
IPC: C10G21/10
Filed: 1937-06-22
Abstract: <PICT:0489456/III/1> In the Edeleanu process of treating hydrocarbon oils with sulphur dioxide, the oil is treated together with a raffinate obtained subsequently with liquid sulphur at a temperature just below the critical solution temperature, separating the raffinate and extract, and cooling the extract whereby a second raffinate separates and is returned to the first stage.  The raffinate and extract are thereby obtained in pure form without the use of very low temperatures.  The extraction may be effected in a series of mixing and settling vessels or in a tower where the solvent and oil flow in counter-current.  A wax-containing oil is extracted at 35 DEG  C. with a mixture of benzene and sulphur dioxide.  After separation into layers, the extract passes through a cooler 2 at 0 DEG  C. to a settling chamber 3.  The separated upper layer of second raffinate is withdrawn through a pipe 4 and returns to the first extraction zone.  The final extract is drawn off through a pipe 5 into a second cooler 6 from which sulphur dioxide vapours are drawn off, and the cold extract is used as cooling liquid for the cooler 2. The final raffinate is then dewaxed and treated p  with fuller's earth.  Specification 433,197 is referred to.

Title: Improvements in submarine signalling apparatus
IPC: G01S1/72
Filed: 1930-06-05
Abstract: 354,903. Detecting and locating subaqueous sounds; switching systems. WALKER, W. L., 1907, Park Avenue, New York, U.S.A. June 5, 1930, No. 17376. [Class 118 (ii).] Apparatus for receiving subaqueous sounds comprises sound receivers, switches for selectively connecting one of the receivers to a transformer, a condenser connected in shunt with a portion of the secondary winding of the transformer and sound - detecting means, e.g. telephones, connected to the transformer. The receivers may comprise microphones located at different points on the ship, the sounds from the microphones being compared as to intensity and the direction of the sound source estimated. To aid this estimation the resistance in the circuit may be varied until the sounds from two microphones appear to be of equal intensity. When it is desired to connect any one of four microphones PA, PB, SA, SB, to the telephone 60, two switches are provided. The former switch comprises four conducting discs 2 .. 5 rigidly secured to an insulated shaft moved by a handle. Brushes 27 .. 38 bear on these discs which are so shaped that a movement of 45‹ in one direction or the other may connect either the brushes 31 .. 34 or the brushes 35 .. 38 with the brushes 27 .. 30, thereby connecting either receivers PB, SB or PA, SA with brushes 23, 25, 22, 24 of the second switch. This is similar to the first switch but contains only two discs 7, 8 and their corresponding brushes 21 .. 26. A 45‹ movement of this second switch will connect either the brushes 23, 25 or 22, 24 to the brushes 21, 26, thus selecting one of the two receivers previously selected by the first switch. A constant current is supplied to the receiver from a battery 20, through a switch 18 (protected by a condenser 19), choke 17 and brushes 21, 26. Current variations caused by received sounds pass along a line 52, through the primary winding 12, 11 of an autotransformer 9 and through a condenser 16 to the line 53. A portion of the autotransformer winding is shunted by a condenser 10 bought into circuit by a switch 15. This condenser is of greater capacity than that required for resonance at the receiving frequency and is stated to eliminate undesired noises. The telephones 60 are connected across the secondary winding of the transformer 9 and are short-circuited by discs 1, 6 and brushes 44, 45, 39, 40, when the selecting switches are in their neutral positions. A rheostat 50 shunted across the secondary winding 9 enables the intensity of the telephone sounds to be varied. Construction of switches. The conducting discs are eccentrically-shaped and are mounted on a shaft 68 covered with insulation 74 and operated by a handle 70 having a pointer 71. Upon the discs bear springy contact strips mounted on bars 64, 65, 66 forming the switch framework. A spring-pressed roller 80 engages locating notches in a disc 75 and a screw 84 in the same disc engages screws on the endplate 62 to limit the extent of rotation of the switch.

Title: Improvements in or relating to a method for producing purified water from aqueous saline solutions
Inventor: FRENCH MICHAEL JOSEPH
IPC: C02F1/00
Filed: 1964-04-28
Abstract: 1,074,144. Purifying saline solutions; refrigerating. BRITISH PETROLEUM CO. Ltd. May 25, 1965 [April 28, 1964], No. 17539/64. Heading F4H. In a method of obtaining purified water from an aqueous saline solution by contacting the solution with a paraffin having 1 to 4 carbon atoms per molecule to from a hydrate, the hydrate is washed first with incoming untreated solution, which is thus pre-cooled, then with part of the purified water. As shown, sea-water from line 15 passes through a first washing stage 12 and line 18 to a vessel 10 where it is contacted with propane introduced through line 21 and expansion valve 30 to form propane hydrate which is removed through line 19. The concentrated brine passes through line 16 to a second vessel 11 and is contacted with propane from line 22 and expansion valve 31, propane hydrate being removed through line 20 and concentrated brine through line 17. The hydrates are combined and passed through first and second washing stages 12 and 13 to a hydrate-decomposing stage 14 for direct contact with compressed propane vapour from compressors 50 and 51. From stage 14, liquid refrigerant is returned to vessels 10 and 11 and purified water is discharged through line 29, part of the water being passed through line 25 to the second washing stage and, after use, being forwarded through line 26 to line 15. Additional cooling in stage 14 is provided by withdrawing propane vapour therefrom, compressing it in compressors 52, 54, liquefying it in heat exchanger 55 then expanding it through valve 56 into a receiver 57, a liquid/vapour stream from the latter being supplied to the inlet of compressor 54. Liquid propane from the receiver is further expanded in valve 32 and supplied to stage 14. The incoming sea water in line 15 may be additionally pre-cooled in heat exchanger 58 which is supplied with liquid propane from receiver 57 through line 59, the propane being returned to the intake of compressor 52. The output streams 29 and 17 of the process may be used to cool propane in heat exchanger 55, which may also be cooled by sea-water not used in the process, and seawater in line 15. Temperature and pressure conditions for the process are specified. In a modification (Fig. 1, not shown) only a single hydrate-forming vessel is employed.

Patent GB-1020789-A (GB)
Title: Improvements in or relating to active alumina
IPC: C01F7/441
Filed: 1963-05-06
Abstract: Active alumina granules are produced by selectively calcining alumina trihydrate to produce a transition alumina (i.e. an intermediate decomposition product between the stable hydrated crystalline form and the completely anhydrous corundum) which is capable of at least partial rehydration, agglomerating the calcined material by mixing with water to produce granules of the desired configuration, curing the granules by immersion in water until substantially rehydrated alumina is obtained and then activating the granules by heating to obtain a transition alumina. The initial calcination may be accomplished by passing alumina trihydrate through hot gases at 1300 DEG  to 1400 DEG  F., and the trihydrate is advantageously calcined to a loss on ignition of 5 to 10%.  The calcined alumina may be ground prior to agglomerating and the granules formed are preferably of diameter between 0.093 and 0.132 inch.  The granules may be cured in water at about 95 DEG  C., either continuously or batch-wise.  The granules may be activated by heating at from 500 DEG  F. to 750 DEG F., preferably 550 DEG  to 700 DEG  F., most advantageously at 600 DEG  F.  The active alumina granules produced have a high hydrocarbon adsorption capacity, especially for hydrocarbons containing at least five carbon atoms.  Regeneration is carried out by heating the saturated adsorbent after use to boil and vaporize the hydrocarbon content. The adsorbent is then cooled, and may then be used for further hydrocarbon recovery adsorption.ALSO:Hydrocarbons may be separated by adsorbtion using active alumina granules prepared by calcination of an alumina trihydrate (see Division C1).  The alumina granules selectively adsorb C5+ hydrocarbons, and can be used in the recovery of natural gasoline from natural gas.
