Title: Improved pneumatic coupling system for railway cars
Inventor: COPE GEOFFREY WILTON
IPC: B61G5/08
Filed: 1970-09-17
Abstract: 1278200 Rail vehicle couplings DRESSER INDUSTRIES Inc 17 Sept 1970 [2 Oct 1969] 44437/70 Heading B7T An automatic coupling system for rail vehicles having a main air line 40 interposed by a main valve operable by means 44, consists of a knuckle coupler which on an intentional uncoupling has its knuckle opened by a ram 100 supplied with pressurized air from means 44 when lever 87 opens valve 47, thus allowing the air to pass from line 53 to the ram via lines 74 and 92, needle valve 95, check valve 97 and reservoir 93. On separation of the vehicle, line 74 is vented since it is uncoupled from counter line 74<SP>1</SP>, but the ram 100 continues to urge open the knuckle until the air in reservoir 93 has been vented through check valve 95, after which the piston 102 returns under spring pressure. The line 40 when pressurized causes the vehicle brakes to remain in their off position and valve 41 is opened on the vehicle being coupled or unintentionally uncoupled, and closed on intentional uncoupling by the means 44. On coupling, plunger 58 is depressed and air in chamber 62 is compressed exerting a pressure on head 55 of valve spool 56. The spool is depressed and pressurized air from line 40, via either check valve 50 or 60 and lines 51, 52 is directed into line 65 which acts on head 66 of spool 67. The spool 67 is depressed and held in this position by spring and ball 75, and pressurized air from line 51 may pass into line 77 and act on head 39 of valve 41 to open it. On an unintentional uncoupling the pressure would be relieved from head 55 due to the retention of its original position of plunger 58 and spool 56 would lift closing off line 52 and venting line 65 through port 86. The spool 67 will still allow air to pass to line 77 keeping valve 41 open due to spring and ball 75. The retention of valve 41 in its open position allows venting of pipe 40 and application of the vehicle brakes. On intentional uncoupling, when lever 87 is moved to pressurize line 74, the air therein acts on head 68 of spool 67 thus moving it upwards, closing line 76 and venting line 77 through port 89. The pressure on head 39 is then relieved, closing valve 41 and retaining pressure in line 40 so that the brakes are not applied. In a modification, the reservoir is replaced by a valve and the ram is vented through this valve into line 51 on an intentional uncoupling. Further the knuckle of the coupler may be opened when the vehicle is not coupled to another vehicle by operating a valve which supplies pressurized air to the ram. If a rail vehicle provided with a system according to the invention is coupled to a vehicle without the system the system on the first vehicle can be operated by pressure supplied through a line 116 coupled to the second vehicle.

Abstract: 1,021,088. Control of A.C. motors. ALLMANNA SVENSKA ELEKTRISKE A.B. Dec. 11, 1962 [Dec. 11, 1961], No. 46653/62. Heading H2J. The driving system of an asynchronous motor comprises primary winding 5 supplied from network 9 through slip-rings 10, and secondary winding 4 associated with rectifier 1 and inverter 2 whereby power is fed back from the winding 4 to the network 9. Speed regulation is effected by means of the inverter 2. The motor also has a braking system comprising short-circuited rotor winding 6, and stator winding 8 which is supplied from variable voltage source 7 connected to network 11. The windings 6, 8 have a different pole-number from the windings 4, 5. When the inverter 2 is adjusted to reduce the speed of the motor, the secondary current falls to a low value whereby a control signal is applied to source 7 to render the braking system effective. The braking torque is reduced when the speed approaches the desired value by regulating source 7 in accordance with the secondary current or other speed-responsive factor. The winding 8 may be connected for providing a reverse torque, and a resistor may be connected in series with winding 6. Reversal of the winding 5 is prevented until braking has taken place. In another arrangement, the primary winding 12 of the driving system is placed on the stator and is formed as a double star-connected winding. The braking field is produced by controlled rectifier 15. Secondary winding 13 of the driving system has two parallel groups per phase to form a short-circuited winding for the braking system having a pole-number different from that of the driving system. The winding 13 is connected to frequency changer 14, Fig. 2 (not shown). In a further embodiment the motor has a squirrel-cage rotor 21, the stator winding having phase coils 20 supplied with direct-current from source 18 for braking. An inverter 19 is supplied from rectifier 17. Source 18 is controlled from rectifier 17 to provide braking current when the power of the driving system drops to a low value, Fig. 3 (not shown).

Title: A process for separating droplets of one liquid from a second liquid which is immiscible with the first
IPC: C10G33/06
Filed: 1963-11-28
Abstract: A fine dispersion of two immiscible liquids is passed through a layer of polyolefin fibres, whereby small droplets are coalesced into larger droplets to facilitate subsequent separation by settling.  The fibres may be polypropylene, of 3100 N diameter, preferably 1060 N, and at least 10, preferably 100, times as long.  Other polymers and/or copolymers of C2-C5 olefines of molecular weight 50,0001,000,000 are applicable. The fibres may be loose, forming a layer 5100 cm thick, supported on or between perforated plates or mesh and weighted down by loose rocks or gravel.  Alternatively the fibres are in the form of felt, in a layer 130 cm thick.  Sections of felt may be piled up in a column, or rolls of felt may be stacked end to end therein, interstices between turns in adjacent rolls being staggered.  The free space in the fibres is 7598%.  In use, any solid matter is filtered off and the 'mixture' settled to separate large droplets; then the 'mixture' is passed through successive layers of fibres, with settling stages between each layer.  The optimum velocity through layers is 0.110 cm/sec.  The layer of gravel used to weight loose fibres may assist coalescence and a gravel layer may be separated from a fibre layer by a gap, the two layers comprising one coalescing unit.  Applications are separation of acids or alkalies from hydrocarbons, and water from oil-water emulsions.

Title: Improvements in or relating to apparatus for imparting a twist to yarn
Inventor: GILCHRIST REGINALD SELBY
IPC: D02G1/08
Filed: 1963-11-29
Abstract: Low tenacity, e.g. diacetate or triacetate, yarn is highly twist-crimped by passing the yarn over or through a heating or setting zone whilst under a low tension, i.e. not more than 0.09 gms./denier, so as to allow the yarn to shrink to the extent determined by the temperature of the yarn within the zone, thence through a twisting apparatus which the yarn enters at the same low tension.  The yarn is twisted by frictional engagement with two or more endless tracks which, with acceptable slip, rotate the yarn without pretension being applied thereto.  The tracks are formed by the inner surfaces of annular members which are supported and driven by endless belt and pulley mechanism and are so disposed in spaced planes in the general direction of yarn travel that, in use, the yarn is diverted by the engaging surfaces of successive tracks alternately in opposite directions so as to follow a zig-zag path therethrough.
