Patent GB-898757-A (GB)
Title: Production of amides
Inventor: YEOMANS BERTRAM
IPC: C07D213/84
Filed: 1959-12-22
Abstract: Aliphatic, aromatic and heterocyclic amides involatile in steam are prepared from the corresponding nitriles, which are water-soluble and steam-volatile, by feeding an aqueous solution of the nitrile into an intermediate stage of a distillation column within which water is refluxing, feeding an aqueous solution of a base having a pH greater than 9 into the column or its kettle and removing the amide produced from the base of the column. Specified bases are ammonia, piperidine and hydroxides, and carbonates of the alkali metals.  The examples describe the preparation of isonicotinamide from 4-cyanopyridine using (a) ammonium hydroxide, and (b) sodium hydroxide as the base; and 3-cyanopyridine is similarly hydrolysed to nicotinamide.  The aqueous solution of cyanopyridine may be supplied as a solution, also comprising picoline and some ammonia, obtained in the production of the cyanopyridine by reaction of the corresponding picoline with ammonia and oxygen.  Propionitrile and benzonitrile are also specified starting materials.

Fuel elements comprising fuel particles coated with pyrolytic graphite and contained in a graphite envelope or embedded in a graphite matrix are disentegrated to separate the coated particles from the graphite of the envelope or matrix by reacting the fuel elements with ferric chloride at a temperature in the region 290- 350‹ C. The pyrolytic graphite is not affected. An apparatus for carrying out the method comprises, Fig. 2, a reaction container, having chambers 1, 2, rotatable about its horizontal axis by a motor 8 and heated by coils 3, 4, 5. The chamber 1 is charged through a sealable aperture 6 with the fuel elements and with the ferric chloride and the entire container is heated to 290-350‹ C. by the coils 3, 4, 5 so that the graphite disintegrates. Chamber 2 is now cooled but chamber 1 is brought to 400‹ C. by the coils 3, 4 so that the ferric chloride evaporates and passes through aperture 2b in partition 2a into chamber 2 where it condenses for re-use, the conical plug 9 being withdrawn from the position shown to open the aperture. The contents of chamber 1 are removed through the aperture 6 by tilting the platform 11, the plug 9 then obstructing the aperture 2b to retain the ferric chloride in chamber 2.

A liquid atomizing nozzle, particularly for use in gas turbine engines, comprises a housing 24 containing a cylindrical swirl chamber 44 to which fuel is tangentially supplied through a passage 26 and exits through an aperture 46, there being snugly received within chamber 44 a sleeve 30 which has an opening 32 defined by the free end of a reed 34 integrally formed with the sleeve. The angular position of the sleeve is such that reed 34 overliespassage 26 and fuel pressure causes the reed to deflect toward the interior of chamber 44, as shown by the phantom lines, thus allowing passage of fuel through opening 32. The quantity of fuel entering chamber 44 will be proportional to the pressure of the fuel. The side 37 of the opening opposite the free end of the reed is bevelled.

The apparatus disclosed in Specification 956,968 is modified in that the lens is stationary and the characters are carried on a movable endless surface in the form of a closed loop. The matrix band, Fig. 6, comprises sections 102 each being a film strip located on a steel band 100 and having character areas 162 arranged in nine rows of alphabets of different type faces. Three adjacent sections 102 are used, for upper case, lower case, and figures &c., these sections being repeated along the band. Alternatively, all the characters may be on one film matrix on the band or on a chain. The band has timing slits 37 and slits 39 indicating the end of a sector, which co-operate with photo-cells, Fig. 9. The interval between characters is 20 units. There may be two projection areas, Fig. 12, each including a cathode-ray tube, to scan two adjoining sections 102 simultaneously and project them on to the same area of the film. A prism 30, Figs. 9 and 10, or 210, 211, Fig. 12, is movable to select the type face, and a lens turret 45, Fig. 10, is rotatable to select point size. The two prisms, Fig. 12, can be used to merge two type faces in one line. The ray tube beam is directed to the desired character at the desired instant, as in Specification 956,968 and may be positioned by using a monitor tube 219 and slave tube 220, Fig. 13. The control circuit shown in Fig. 7 is similar to that shown in Fig. 14 of Specification 956,968, but is modified in that the storage 235 is divided into three storage sections 16, 15, 21, for character displacement values, accumulated width value, and composition instructions. Line spacing of the film 8, Fig. 10, is controlled by an electromagnetcontrolled roller 206 and a magnet-operated clamping plate 204. Alternatively, the characters can be projected in the order in which they appear on a printed sheet at a slower operation by means of the control system shown in Fig. 11, which omits the sorting circuits indicated at 18, 19, 20, 82, 12 and 126 in Fig. 7. In this case, the most frequently used characters are repeated along the matrix band.

The harness strap 10 has length adjusting means e.g. two snubbing buckles connected by a short length of webbing in the lap strap portion so that the strap may be adjusted without displacing the buckles from the middle of the lap strap. The strap 10 makes running connections with the anchor points I, II by means of two D-rings 8, 9 which are restrained against upward movement by straps 11, 12. At the third anchor point III the ends of the strap 10 are formed into loops 18, 19 (Fig. 3) and are passed through a slot 17 on a fitting 14 and are held in place by a pin 20. The pin 20 is attached to a tab 21 to enable the pin to be withdrawn quickly and the tab 21 is provided with a press stud 23, 24 so that the tab 21 can be fitted around the straps to prevent accidental release. In a modification (Figs. 4, 5 not shown) the two loops on the end of the strap 10 are secured by separate pins provided by the two arms of a U-shaped member on the tab 21.

An edging stand, which rolls the edges of a strip 12 being fed to a tube welding plant, includes a pair of edging rolls 14, 14<SP>1</SP> which are continuously oscillated in a vertical plane during rolling. The working life of the rolls is thereby prolonged. Each roll is oscillated by rotation of a threaded shaft 21 driven from a motor 17.

The rolls are each pivotally mounted at 27 in a frame 26, rotation of a turnbuckle 28 adjusting the inclination of the roll relative to the frame. The two frames are movable towards and away from each other by rotational adjustment of a threaded rod 30.

Abstract: 1437807 Measuring line impedance SIEMENS AG 1 Oct 1973 [29 Sept 1972] 45826/73 Headings G1U [Also in Division H2] Line impedance is measured by determining the values of the current through, voltage across and rate of change of current in the line for two different time instants. The rate of change may be replaced by the change in current over a predetermined time and the voltage and current values may be sampled at two instants or averaged over the predetermined time. The measured impedance is used to detect the location of a fault on the line. The six measured values are processed to provide the resistive and inductive components R 1  L of the impedance as follows:- and where A 1  D represent the current values; B, E the rate of change current; C 1  F the voltage values. In the embodiment, six values of voltage and current are sampled and stored 28, 29. Four groups of three values each are averaged (e.g. 32-35) to provide the values of voltage and current 51, 52, 54, 55 and the rate of change values are determined by differencing 36, 37. The six values A-F are then processed according to the required equations above to provide values representing R and L. At each processing stage, gates are provided which detect the completion of processing and operate relays to pass the processed outputs to the next stage Fig. 1, (not shown).
