Title: Control of fluid flow processes
IPC: B01D3/42
Filed: 1968-01-03
Abstract: 1,207,195. Distillation and liquid/liquid extraction columns, control. MONSANTO CO. 3 Jan., 1968 [4 Jan., 1967], No. 396/68. Headings B1B and B1F. [Also in Division C5] A distillation or liquid/liquid extraction column is regulated by an analytical device which measures a property representative of the composition of an effluent stream from the column, and sends a signal to an automatic controller, of the non-continuously variable type, which regulates the flow-rate of an effluent stream so that the rate periodically changes from one preset value to another. As shown, a mixture-to-be-separated, e.g. a mixture of ethylbenzene and xylene isomers, is fed through line 11 into distillation column 11 A bottoms product, comprising the heavier components of the feed mixture, is withdrawn through line 12. The overhead vapour, comprising the lighter components, is led through line 13 to condenser 14. Part of the condensate is refluxed to the column through line 15, and the remainder is withdrawn from the system through line 16. The composition of the product stream in line 16 is measured by analyser 17 which sends a signal to controller 18. This controller regulates valve 19 so that the flow-rate in line 16 is at the higher of two predetermined values when the purity of the overhead product is above the desired purity, and regulates the valve so that the flow-rate is at the lower of the two values when analysis shows that the overhead product is below the desired purity. The analysis may be carried out by chromatography. If the composition of the bottoms product is to be controlled, this may be effected by measuring the temperature-differential between a point in the lower section of the column and at the reboiler inlet. A liquid/liquid extraction column may be controlled by an analyser, controller and two-set valve associated with the bottoms product from the column.

Title: Improved apparatus for measuring the flow-velocity of gases in the flues of furnaces and the like
IPC: G01L7/00
Filed: 1922-01-06
Abstract: 174,338. Siemens & Halske Akt.-Ges Jan. 20, 1921, [Convention date]. Gas meters.-In apparatus for measuring the draught in the flues of boiler furnaces, and alsc for measuring the carbonic acid content of flue gases, use is made of the variation in the resis. tance of an electrically-heated wire which is exposed to the cooling effect of air or gases induced by the flue draught or drawn from the flue. In the apparatus two points of the furnace flue in which the draught is to be measured are connected by pipes 5, 6 to chambers 1, 2 respectively open to the atmosphere at 7, 8. The chambers 1, 2 contain electrically heated measuring-wires 3, 4 arranged as two arms of a wheatstone bridge, the other two arms of the bridge being indicated by the resistances 10, 11. According to the difference of pressure at the two points of the furnace flue, air flows at different velocities through the pipes 5, 6 and cools the electrically heated wires to different degrees. The temperature difference of the wires is a measure of the pressure difference in the flue, and theerfore a measure of the velocity of the draught. The temperature difference of the wires 3, 4 is measured by determining their resistance difference by the galvanometer 9. In some cases it is sufficient to determine the partial vacuum at one point only in the flue. In such a case one of the chambers 1, 2 is shut off so that it contains air only, air being drawn by the flue through the other chamber. When it is desired to measure the carbonic-acid content of flue gases, one of the chambers 1, 2 is filled with air and closed while the flue gases are drawn through the other. Owing to the lower conductivitv of carbonic acid a greater heating effect of the wire over which it flows is produced, and the temperature of the wire thus constitutes a measure of the carbonic acid content.

Abstract: 861,174. Valves. CONSILIA-FIDUCIAIRE. Jan. 7, 1958 [Jan. 8, 1957], No. 578/58. Class 135. [Also in Group XXVIII] An aerosol valve comprises a non-metallic cylindrical chamber 3, 4, Fig. 2, incorporating an upper part 4b joined to a main portion 4a by an annular resilient part 8 ; the portion 4a has a depending conical part 3 leading to a socket 15 for a pipe 16, Fig. 1, within the aerosol container 1. A flange in part 3, Fig. 2, supports an upstanding stem 5 with a valve head 6, and the pressure fluid in the container 1, passing through a passage 9 in the flange, acts on the part 8 so pressing the tapered part 4b against the head 6. Upon depressing a button 7, the part 4b leaves the head 6 and allows the fluid to emerge in atomized form from an outlet 12 which communicates with an annular chamber 11 in the button via a port 13. A protrusion 10 in the chamber 11 acts as a button stop when it abuts the head 6 ; a whirling motion is imparted to the fluid in chamber 11. A spring, not shown, may be disposed between the diaphragm and flange. The valve is secured in the container 1, Fig. 1, by forming the neck 2, as shown, around the body 4, the whole being enclosed in a metal sleeve 17. In another embodiment the body is formed with a radial flange that is supported by a plate, both of which are turned over at the outer end with the lip of the container into a scroll of more or less than 360 degrees.

Abstract: 1,124,576. Measuring magnetic fields. RELIANCE ELECTRIC & ENG. CO. Jan. 6, 1966, No.694/66. Heading G1N. [Also in Division G3] A Hall generator 10 for measuring a magnetic field is provided with an adjustable excitation current supply 18, Hall voltage output leads 26 and a calibration coil 32 supplied from a signal generator 36. The Hall voltage ouput signal Eh contains a component fk representative of the magnetic field produced by the coil 32 and a component fs representative of the magnetic field to be measured. The component fk is isolated by a filter 42 and from it is produced a direct voltage Ek which is compared by means of a chopper 54 with a standard voltage E std, any error signal being applied to control a servomotor 5 which operates in association with the source 18 to adjust the excitation current in a sense to reduce the error to zero. Thus the excitation current is automatically varied to correct for variations in the Hall effect voltage caused by changes in an ambient condition such as temperature, so that the signal fs, which is applied to a suitable analysing circuit 40 over a low pass filter 38 is rendered independent of such changes, and the relationship between a given change in magnetic field and the resultant change in Hall voltage is maintained constant. The comparator and regulating circuit may take different forms and three modified circuits are described with reference to Figs. 2, 4 and 6 (not shown).

Abstract: 782,846. Filling-machines. MEDWAY PAPER SACKS, Ltd. Jan. 9, 1956 [Jan. 10, 1955], No. 721/55. Class 94(1). In a filling machine for sacks, &c. which incorporates weighing and agitating devices, connection is provided between these devices whereby when agitation is initiated, the weigh beam is held stationary. The machine may comprise agitating apparatus 7 as described in Specification 743,538, this apparatus being driven by a motor 17 and brought into operation by a solenoid 18. Actuation of the solenoid causes a lever 10 to pull downwards by means of two Bowden cables 11 (one only shown), one side 4 of the weigh beam 2 whereby the beam is rendered stationary. In operation, a sack is placed on the filling nozzle 3 and a handle 5 pulled down to open the feed gate and to set off an electrical timing device. When the sack is three quarters full the feed gate is closed automatically and agitation with consequent immobilization of the weigh beam commences. After a period determined by the timing device, agitation ceases and filling may be completed by a dribble feed or by hand. A further period of agitation is then initiated by a manual switch to complete the process. An electrical connection between the weigh beam and agitator may be provided in lieu of the mechanical connection shown. The first period of agitation may be initiated by the shutting of the feed gate instead of as above.

A switch for flashing vehicle signal lamps comprises a metal frame 17 carrying an electromagnet relay core 18 and a fixed contact 22, and pivotally supporting an L-shaped armature 32 having contacts 27, 34. A spring arm 23 carrying a contact 25 and mounted on an insulating base 16 is biased towards the contact 22, a high-resistance wire 30, when cold, holding the contacts 22, 25 disengaged. Closure of a selector switch 15 to energize a pair of signal lamps 13, 13<SP>1</SP> or 14, 14<SP>1</SP>, completes a circuit from battery 11, core 18, frame 17, conductor wire 26, resistance wire 30, arm 23, conductor wire 42, relay coil 35, conductor wires 43, 46, to the lamps. The resistance 30 limits the current to a value insufficient to illuminate the lamps or to operate the relay. Expansion of the wire 30 upon heating permits contacts 22, 25 to engage whereupon the wire is short-circuited and the increased current illuminates the lamps, and the armature 32 is operated to close contact 27 upon the upper end of contact 25. Operation of the armature thus completes a further shunt circuit around the wire 30, and contact 34 engages a contact 36 to energize a pilot lamp 12. As wire 30 now cools, contact 25 leaves contact 22 under " no-load conditions and arcing does not take place due to the further shunt circuit; also, the movement of contact 25 along contact 27 cleans these contact surfaces and the contact 25 eventually disengages contact 27 to deenergize the lamps and the relay, a fast break being produced by an armature spring 38. The wire 30 then heats up again and the cycle is repeated. Should one of the signal lamps of the selected pair be faulty the current through the coil 35 is insufficient to operate the armature. Specification 729,250 is referred to.

Abstract: 1413768 Rollers AVERY PRODUCTS CORP 8 Jan 1974 [2 Feb 1973] 00734/74 Heading F2U The surface of a web-guiding roller is shifted axially during rotation in response to the bodily displacement of the roller as by an hydraulic cylinder 26. The roller body 30 is supported by ball bearings 23 on a non-rotary shaft 21 which is keyed for axial movement in a block 14 provided with a boss 15 so that it can be clamped in any angular position by a split block 12. The block 14 also carries a cam plate 47 in which rides the follower 45 of an arm 44 attached at its opposite end to the non-rotary inner ring 41 of the swash plate. When the shaft 21 is bodily displaced by the hydraulic cylinder 26 automatically in response to sensors monitoring the lateral deviation of the web, the arm 44 moves to tilt the swash plate about a pin 49 to cause pins 51 on the rotary ring 42 of the swash plate to reciprocate slats 32 which are covered with an elastomeric surface 34 and slide on ball bearings in dovetailed grooves. For some web materials the steering action may be improved by adjusting the angular position of the pin 49; this may be done during operation by loosening the bolt 53 of the split block 12, rotating the block 14 and consequently the shaft and pin 49 and then retightening the bolt 53. If desired the roller may be covered with a rubber sheath, the axial motion being imparted to it by the slats.
