Title: Improvements in or relating to the fractionation of free fatty acids
IPC: C11C1/00
Filed: 1947-11-13
Abstract: A relatively unsaturated fraction is separated from a mixture of free fatty acids substantially free from oxidized fatty acids by introducing the mixed fatty acids into a vertical column at a point between the ends thereof, introducing a polar solvent substantially immiscible with a non-polar petroleum hydrocarbon solvent of lower specific gravity used in the process into the column at a point above that at which the acids are introduced, introducing the hydrocarbon solvent into the column at a point below that at which the acids are introduced, maintaining a temperature within the column at which the components of the mixture remain in the liquid state but below that at which the hydrocarbon solvent phase and the polar solvent phase are completely miscible, and withdrawing a relatively less unsaturated raffinate and a relatively more unsaturated polar solvent extract from opposite ends of the column.  The non-polar solvent may be a paraffinic hydrocarbon such as iso-octane and the polar solvent may be furfural.  A list of other polar solvents which may be used is given.  The mixed fatty acids fractionated may be those of marine oils, such as menhaden, sardine, whale or cod oil, or those of linseed, tung, soya bean, cottonseed, perilla, and palm oil, or of fats such as lard and tallow.  The volume ratio of polar to non-polar solvent may range from about 4 : 1 up to 10 or more of the latter to one of the former.  The volume ratio of the fatty acid mixture to that of the solvent mixture may range from 1 : 1 up to 12 parts of the solvent mixture to one part of acids.  The extraction column and the feed conduit for the fatty acid mixture may be furnished with jackets through which temperature control media are circulated. Specification 658,967 is referred to.

Title: Improvements in or relating to electrical boosters
Inventor: MARTIN LEONARD JOHN
IPC: H01H9/00
Filed: 1954-10-21
Abstract: 782,988. Automatic regulators. BRENTFORD TRANSFORMERS, Ltd. Oct. 18, 1955 Oct. 21, 1954], No. 30392/54. Class 38 (4). In an automatic voltage regulator an electric motor operates a multi-contact switch against a mechanical bias which returns the regulator to its minimum voltage position if the voltage falls to zero and uncouples the motor from the switch. In Fig. 2, an electric motor 1, under the control of the voltage of an electric power supply line, adjusts, through an electromagnetic clutch 2 and sprocket chain 6, a shaft 5 to which is coupled a multi-contact type voltage regulator (not shown) which thus maintains the supply voltage constant automatically. If for any reason the voltage falls to zero, clutch 2 is automatically de-energized so that motor 1 is uncoupled and the voltage regulator moves to its minimum position due to the effect of gravity on one of its moving parts and/or the effect of a weight (not shown) suspended from a cable 22 wrapped round a drum 21 on shaft 5. The weight is in two parts one of which is detached automatically at a certain point during descent so that the effect of the weight is reduced as the regulator approaches its minimum position. A pointer 8 and meter 20 indicate the position of the voltage regulator. A switch 1a may be operated to de-clutch motor 1 at any time and removal of an inspection cover (not shown) allows a pawl to engage a ratchet 30 associated with drum 21 so that the weight cannot fall during inspection and can only be raised by operation of a hand wheel 35.

Title: Improvements in electric interlocking plants for railways
IPC: B61L7/06
Filed: 1931-11-03
Abstract: 385,700. Railway-points control. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Nov. 3, 1931, No. 30482. Convention date, Nov. 25, 1930. [Classes 104 (i) and 105.] Apparatus for the transfer of the control of points from the signal cabin lever to a local yard lever is so arranged that the change back to the cabin lever control can only be effected when the cabin lever is in a position corresponding with the points setting. The transfer apparatus comprises a manual switch LB and a relay LR with contacts 14, 15, 16, 18. The cabin lever VS actuates contacts 1 .. 6 and is subject to locking by a locking relay SM. The lever VS when moved also moves a changeover switch BS to apply a high-voltage battery A for the points operation and on completion of such operation a magnet KM releases the switch BS which is returned by a spring F and re-inserts a low-voltage battery B. To transfer the control to a yard lever LM the switch LB of the transfer apparatus is opened to de-energize the relay LR and the cabin lever VS is put to a mid-position operating the change-over switch BS to apply the battery A over contacts 13, 6, 15 to the yard lever LM and lamp L<2> which lights up indicating that this lever LM now has control, Fig. 4, and may be moved to the position shown to actuate the points motor M over the points circuit controller MS. To return to cabin control the transfer switch LB is closed and the cabin lever VS moved to an end position which must correspond with the points setting to permit the relay KM to be energized to close its contact 19 and pick up the transfer relay LR which is then held by its stick contact 14 and closes its contact 16 to apply the battery to cabin lever contact 4 in readiness for operation of the points motor when the cabin lever VS is next put over. The circuit to relay KM is over contacts 13, 5, contact 9 or 8 of points-controlled device MS according to the setting of the points, and contact 2 in the correct position of the lever VS. Approach locking is effected by a track relay SR which de-energizes the locking relay SM to lock the cabin lever VS. If, however, the points are under the yard lever control the cabin lever VS is not locked as the relay SM remains energized over back contact 18 ; the cabin lever may therefore be moved to an end position and if it is then in correspondence with the points setting the relay KM is energized and permits an interlocked proceed signal to be cleared. The yard lever cannot now operate the points as the contact 6 is now open. In the end positions of the points the motor M is earthed over the contacts 12, 3 and 7 or 10. The transfer switch LB may be mechanically coupled with the cabin lever VS or this switch LB may mechanically actuate the contact 6 which is then separate from the cabin lever VS. The transfer switch LB may be replaced by a manual switch operating the contacts 14, 15, 16 and locked by the relay LR during yard lever control. A single transfer relay LR may control a number of points.

In one embodiment (Fig. 3) the fusible linkage comprises a wire loop 29 which is supported from a hook 31 and passes beneath a block 19 of flux at the lower end of a height-adjustable head. The hook 31 supported from a rod 6 movable in a cylinder 11 to effect movement of the contact member 3. Motion of rod 6 is transmitted to member 3 via a compression spring and means are provided for indicating the pressure with which member 3 contacts the welding electrode 35. The device is set up so that it presses the electrode into the joint, the block 19 pressing on the electrode in advance of the contact member 3. In use, a plurality of devices are spaced along the electrode and adjusted to exert the same pressure. A welding current source is connected to the devices. As the arc fuses the electrode to approach the first device, the fusible linkage melts, allowing rod 6 and hence contact member 3 to spring upwardly releasing the electrode. The succeeding device then proceeds to supply current so that the arc continues. In the second embodiment (Fig. 6) the fusible linkage comprises a fuse wire 39 which, in use, contacts the electrode 35 and which is connected, through a perforated guide pipe 40 to a non- fusible wire 29<SP>1</SP>. In performing welding a butt joint or a fillet weld can be executed. The electrode is retained in spaced relation with the workpieces by the use of insulating spacers.

Abstract: 1,183,576. Dyeing process and apparatus. F. JONES. 29 June, 1967 [9 July, 1966], No. 30949/66. Headings DIB and D1L. Substrate materials, e.g. polyesters and polyamides, are dyed by passing a dye-charged gas over or through the substrate material at an elevated temperature at which the dyestuff diffuses into the substrate material, the dye-charged gas being produced by passing a carrier gas, e.g. air, steam or nitrogen, over heated solid volatilisable dyestuff. Anthraquinone disperse dyes are used. The carrier gas may be heated to volatilise the dye and may contain further substrate conditioning compounds. A closed system containing both substrate and solid dye may be used through which the carrier gas is continuously recirculated, the flow direction being optionally reversed. In an apparatus for carrying out the above process carrier gas from blower 11 takes up volatilisable dye from a tray in dyebox 17, is passed through a change over butterfly valve 8 which controls the direction of carrier gas flow through the kier openings 5 and 6, and is then circulated over or through the substrate in kier (4) provided with a heating means (24). The carrier gas is then returned to the blower 11. The conduits may be provided with electrical band heaters to maintain the carrier gas temperature and the apparatus may be cleaned of deposited dye by reheating the system and passing the carrier gas over a cold spot e.g. a cooling tube instead of the dye tray to deposit the entrained dyestuff.
