Title: Substituted Phosphanilic Acids and their production
Inventor: CHRISTENSEN BURTON GRANT
IPC: C07F9/38
Filed: 1968-01-29
Abstract: 1,189,772. Halo-substituted phosphanilic acids and intermediates therefor. MERCK & CO. Inc. 29 Jan., 1968 [31 Jan., 1967], No. 4531/68. Heading C2C. The Specification describes and claims compounds of the general formula in which R 1  is H or Br and R 3  is H, or R 1  is F and R 3  is H or F; and R 2  is F or, provided that R 1  and R 3  are not both H, R 2  is H. The compounds, other than those in which R 2  is F, are prepared by reducing the corresponding nitrobenzene phosphonic acid either chemically e.g. by a reducing agent such as (NH 4 ) 2 S, or catalytically e.g. by reduction with H 2  and a noble metal catalyst such as Pd on BaSO 4  or PtO 2 , or by H 2  and Raney nickel. The nitrobenzene phosphonic acid may be prepared from the corresponding nitroaniline by treating the latter with a nitrite (e.g. NaNO 2 ) in the presence of fluoroboric acid to give a diazonium fluoroborate which is then reacted with a phosphorylating agent such as a phosphorus trihalide in the presence of cuprous ion (e.g. Cu 2 Cl 2 ). The invention also includes the production of 3-halo phosphanilic acids by first reacting a 2-halo (e.g. 2-chloro, bromo or fluoro)-4-nitroaniline with phthalic anhydride to form a phthalimide which is isolated and then reduced, suitably by catalytic hydrogenation in an acid medium such as glacial acetic acid, e.g. in the presence of a noble metal catalyst, to produce an N-(2-halo-4- aminobenzene) phthalimide. The latter is then diazotized and the diazonium salt converted into the corresponding phosphonic acid as above. Specified products are 2-fluoro-2-bromo-, 3- fluoro- and 2,6-difluoro-4-aminobenzene phosphonic acid. The compounds have bactericidal properties. In Example 3, 2,6-difluoro-4-nitrobenzene phosphonic acid is prepared from 2,6-difluoro- 4-nitroaniline by the method described above. In Example 4, N-(2-fluoro-4-nitrobenzene)- phthalimide is prepared by reacting 2-fluoro-4- nitroaniline with phthalic anhydride. It is converted into the corresponding amino compound by reduction with H 2 /Pd on BaSO 4 , in glacial acetic acid. The amino compound is converted into its diazonium fluoroborate by reation with fluoroboric acid and NaNO 2  at 5‹ C. In Example 3, 2,6-difluoro-4-nitroaniline is prepared by heating liquid ammonia with 2,6-difiuoro-4-nitroanisole in a bomb-tube at 100‹ C.

Patent GB-1221926-A (GB)
Title: Method of control of distillation columns
Inventor: AUCKLAND MICHAEL HILTON TAYLOR
IPC: B01D3/42
Filed: 1967-01-31
Abstract: 1,221,926. Distillation columns; control. BRITISH PETROLEUM CO. Ltd. 25 Jan., 1968 [31 Jan., 1967], No. 4582/67. Heading BIB. [Also in Division C5] The continuous distillation of a multi-component feed mixture, such as crude petroleum, in a distillation column is automatically controlled to maintain the minimum allowable difference between the temperature of at least one liquid or vapour withdrawal stream from the column and a theoretical reference temperature (TRT), defined as the bubble point or dew point of a perfectly fractionated liquid or vapour cut, by measuring the temperature at the withdrawal point and operating the column so as to increase the amount of heat withdrawn from the column above the withdrawal point, if the temperature difference exceeds the minimum. As shown, the feed is introduced into column 1 through feedheater 13 and line 27, the flow of heating-medium being controlled by controller 11 and temperature-sensing device 12. A bottoms product is withdrawn from the column through line 28. The overhead vapour flows to condenser 2; and a portion of the condensate is withdrawn as overhead product through line 23, the remainder being refluxed to the column through line 22. A cooler (not shown) and lines 25, 26, provide a circulating reflux system below the withdrawal point 24, the flow in the circulating system is controlled by valve 19 and flow-controller, 17. The quantity of heat removed by the circulating reflux system is measured by device 18 which receives signals from temperature-sensing devices 14, 15 and a flow-measuring device 16. The temperature of the side-cut removed via line 24 is measured by device 7. The TRT is derived by a device 8 which receives information concerning the flow-rates of the feed and product streams from device 9. The difference between the withdrawal temperature and the TRT is calculated by device 10 which sends signals to either or both controller 11 and device 18. An increase in the temperature-difference increases the feed temperature and/or decreases the quantity of heat removed by the circulating reflux system. The temperature of the overhead vapour is measured by device 4 which sends a signal to the controller 5 of valve 6, so that an increase in the vapour-temperature causes the flow of top reflux supplied via line 22 to increase. In the distillation of crude petroleum, sidestreams comprising naphtha, kerosine, light gas oil, and heavy gas oil may be withdrawn from the column. The sidestreams may be steam-stripped, the stripper overheads being returned to the column; and steam-injection may be used in the main column.

Abstract: 559,510. Making turbines. BRITISH THOMSON-HOUSTON CO., Ltd. March 22, 1943, No. 4604. Convention date, March 28, 1942. [Class 83 (ii)] [Also in Group XXVI] A bladed wheel or fixed nozzle diaphragm is formed of a disc 10 with a rim 11 having radial projections 12, usually crescent or aerofoil shaped, upon which are fixed curved hollow blades 13 preferably by stitch or spot welding 14. Where a shroud ring 15 is fitted, internal projections 18 are likewise secured to the blades. The ring ends 16 are rabbeted together at 17. To form the projections 12 the rim of the disc is machined along two lines parallel to the rim edge, and diagonally across the rim to form a rectangle for each projection. The projections are then shaped on a milling and copying machine. The blades are produced by forming and pressing thin sheets of steel and the rear edges being fused together. On the shroud band, the projections may be produced as described above, or by a punching and forming process, and may be tapered from front to rear. Fig. 8 shows a turbine casing 36 supporting a diaphragm 37. The latter includes a nozzle structure having spaced partitions 38 with ends secured to an inner band 39 and an outer band 40 respectively. The band 40 is welded to the ring 44 by welds 45, and the band 39 welded to a disc 46.

Abstract: 699,334. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 21, 1952 [Feb. 27, 1951], No. 4617/52. Class 38 (iii) When a split phase induction motor 1 is at a standstill and a two-way switch 16 is moved to engage contact 8, a field winding 2 of the motor is energised through coil 9 of relay 10, contact 14 of relay 13, and contact 23 of speedresponsive switch 22, the other field winding 3 of the motor being energised through capacitor 7 whereby the motor starts in one direction of rotation. The lifting of the relay 10 opens contact 15 to prevent operation of the relay 13, and engages contacts 32, 34, so that, when the motor speed reaches a predetermined value and the speed responsive switch 22 opens its contact, the winding 3 is disconnected but the winding 2 remains energised for normal running of the motor. Movement of the switch 16 to engage contact 11 causes the relay 10 to drop and the field windings of the motor are inter-connected through switches 27, 28, and the capacitor 7 for braking operation until the motor speed falls sufficiently to allow contact 23 to close. The field winding 3 is then energised through contact 15, coil 12, and contact 23, the field winding 2 being energised through capacitor 7 so that the motor is started in the reverse direction. When the centrifugal switch again opens, the energisation of the field winding 3 is maintained through contacts 33, 35.

Title: A system of connections for telephone installations
IPC: H04Q1/446
Filed: 1928-02-14
Abstract: 299,295. Siemens & Halske Akt.- Ges. Oct. 22, 1927, [Convention date]. Manual exchange systems. - In systems in which signals are transmitted over a telephone line by alternating currents of a frequency within the voice range, the receiving arrangements comprise linked rectifiers I, II, associated with filter circuits F1, F2, the latter of which passes only the signal frequency whilst the former passes all other frequencies but rejects the signal frequency. Signal currents passing through filter F2 and rectifier II operate relay M, but if other frequencies are, present the operation of rectifier I renders rectifier II non-conducting so that a momentary speech current of signal frequency will not operate relay M. A high resistance and condenser in the grid circuit of the rectifier II render the current in relay M independent of changes in the amplitude of the signal frequency, provided this is above a definite critical value. An amplifier may be inserted between filter F1 and transformer Ue3. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the anode circuit of the rectifier I includes a relay controlling normally-closed contacts in series with relay M or with a further relay controlled by relay M. This subjectmatter does not appear in the Specification as accepted.

Title: Improved power machine for use in the cutting of the pile of pile fabrics thereon
IPC: D06C13/08
Filed: 1920-02-18
Abstract: 162,443. Fleming, J. H. Feb. 18, 1920. Feeding and registering webs. - In a machine for cutting the pile of pile fabrics, the material is drawn under tension through the machine by a roller driven by a resilient power device, and is allowed to pass over a second roller driven by a high-speed motor, which is stopped when the cutting-knife assumes an inoperative position, thereby applying an overload which the resilient motor is unable to overcome, the travel of the fabric thus being stopped. As shown, the fabric is drawn through the machine by a roller c, Fig. 1, driven by a pneumatic motor or a power-driven frictionclutch, and travels past a brush roller c<2> to a scray e and to a driven roller d, from whence it passes to the cutting-knife l, guide-rollers being provided. The roller d is driven through wormgear by an electric motor k<3>, and the knife carried by a bar o is guided on rods o<5> and is traversed across the fabric by means of hand-operated screwed rod o<6>. The knife l has a haft l<1>, Fig. 4, adapted to rest on the fabric, and is provided with an iron armature l<2>, which during normal working is held by an electromagnet carried by the bar o, a metallic projection l' on the haft normally contacting with parts on the electromagnet device to complete the circuit for energizing the magnet and for driving the electric motor k<3>. The magnet device is slidable under the influence of a spring in a slot in the bar o and carries brushes m<6> making contact with strips o<2> on the bar. When the knife assumes an inoperative position, the circuit is broken by the projection l<3> ceasing to make contact with the magnet device or by the parts m<6>, o<2> being moved out of contact.

Abstract: 988,905. Screwing-up. REED ROLLER BIT CO. Feb. 8, 1962, No. ;4933/62. Heading B3N. A pneumatic rotary tool comprises a normally-open valve 33 to control air supplied to the motor 7, means 46 for locking the valve open, means 65 to unlock and close the valve in response to a predetermined torque and means 50 to reopen and lock the valve when the pressure drops below a predetermined level. In operation, when the tool has been used for screwing-up a nut, resistance to rotation causes a driving shaft 19 to stop, while continued rotation of the motor causes balls 21 to be carried round a hexagonal member 20, thus forcing them outwardly and moving a clutch member 14, 12 rearwardly. The clutch has a shoulder 29 which moves the rod 55 rearwardly and releases the locking catch 46 from beneath a shoulder 52. Release of the catch allows air entering passages 9, 59 to force the valve 33 upwardly and cut off the air supply to the motor. When pressure in the line is cut off, the spring 50 forces the valve back to its open position and re-engages the catch. Several tools 32, Fig. 4, may be operated from a common valve 65.
