Title: Preservation of materials
Inventor: MORLEY JOHN SELWYN
IPC: D21C9/00
Filed: 1953-05-18
Abstract: The invention comprises new compounds of the formula <FORM:0757999/IV(a)/1> where the phenyl nucleus A is substituted with at least one halogen atom and may also have other halogen atoms and/or alkyl radical substituents of not more than 4 carbon atoms; where X represents O or NH, and Y represents Cl when X is O or Y represents OH when X is NH; and where R and R1 are hydrogen or alkyl radicals of not more than 4 carbon atoms, and may be the same or different.  Compounds where X is O and Y is Cl may be obtained by reacting the corresponding compound where X is O and Y is OH with a halide or oxyhalide of phosphorus or with thionyl chloride at a temperature above 50 DEG  C., or by reacting the corresponding oxazoline derivative with hydrogen chloride.  In examples 3:5-dichloro-2-hydroxy-benzoic - N - b  - chloroethylamide is prepared by reacting 3:5-dichloro-2-hydroxybenzoic-N-b -hydroxyethylamide with phosphorus oxychloride and reacting 2-(31:51-dichloro-22-hydroxyphenyl) oxazoline in chloroform with ether saturated with dry hydrogen chloride. Compounds where X is NH and Y is OH may be prepared by reacting the corresponding compound where X is O and Y is Cl with an excess of ammonia at a temperature above 50 DEG  C.  In an example 3:5-dichloro-2-hydroxybenz-N-b -hydroxyethylamidine is prepared by reacting 3:5 - dichloro - 2 - hydroxybenzoic - N - b -chloroethylamide with a concentrated aqueous ammonia solution.

Title: Improvements in or relating to electric motor controllers
IPC: B60L3/00
Filed: 1934-05-08
Abstract: 438,197. Actuating controllers. WILSON, H. G. A. R., Davenset Works, Evington Valley Road, Leicester. May 8, 1934, No. 13899. [Class 38 (iii)] A controller comprises an automatically operated pivoted arm 5, means 15 whereby the arm can be positively moved to and held in a normal inoperative position, said means being capable of actuation independently of the arm to release the latter for automatic action, a series of contacts 1 arranged in a row in the direction of the length of the arm so as to be respectively at different distances from the pivot 8, said arm when released operating contactually upon the contacts 1 in succession commencing with the one nearest the pivot, and time delay means 11 for controlling the movement of the arm when it is released. Depression of a pedal 16 against the action of springs 17 withdraws a rod 15 from the arm 5 which is then free to move under the influence of a spring 9 to bring a contact strip 6 into sequential engagement with the contacts 1, the rate of movement being determined by the adjustment of the spring 9 and a dash-pot 11. When the pedal 16 is released it is moved upwardly by its springs 17, and the rod 15 forces the arm 5 against the action of the spring 9 to its raised inoperative position, a spring 13 moving the piston of the dash-pot also upwardly in readiness for the next operation. Partial operation of the pedal 16 gives the sequential closure of a corresponding number of contacts 1. The contacts 1, 6 may control electromagnetic switches. The spring 13 may be so arranged that it is fully extended or is weakened when the arm 5 is in its normal position, and increases its strength as the arm 5 moves downwardly. The contacts 1, which are carried by a strip 2 mounted at an adjustable angle to the horizontal, are each pivotally mounted and biassed upwardly by a spring. The contact strip 6 is adjustable, and an adjustable stop 23 limits the downward movement of the pedal 16. The rod 15 may have a slotted connection with the arm 5, and the arm may be guided by a bifurcated plate 29.

The springy flange 6 snaps past the projections 9 and the spool is thus secured in position. The mouth of the cage is formed with an outwardlv directed shoulder 11 which guides the entering spool. Specification 292,004 is referred to.
Patent GB-727106-A (GB)
Title: Improvements in the filtration of sludges
IPC: B01D37/00
Filed: 1953-05-19
Abstract: A process for the continuous filtration of amorphous precipitation sludges comprises plotting a filtering efficiency curve for the sludge, i.e. curve with the rate of filtration of the sludge for a given filter area on the ordinate and the solids concentration of the sludge on the abscissa, determining the point on the curve at which the initial relatively gently-ascending portion gives way to a relatively steeply-ascending portion, and applying sludge to the filter at a concentration corresponding to a point on the steeply-ascending portion of the curve substantially past the point at which the curve begins to ascend steeply.  The concentration may be effected in any known manner, e.g. with thickening or settling devices.  The concentration of a cobalt hydroxide sludge is increased from 30 g./l. to about 1,200 to 1,300 g./l., the resultant filter cake having a moisture content as low as from 40 to 50 per cent. Mixed iron-compound-containing sludge on being concentrated from 120 to 1,200 g./l. yields, after filtration, filter cakes having a moisture content as low as from 30 to 35 per cent.

Filed: 1944-07-24
Abstract: 582,474. Printing-surfaces. NATIONAL CASH REGISTER CO., Ltd. (National Cash Register Co.). July 24, 1944, No. 14079. [Class 100 (ii)] A resilient porous printing-surface which is maintained constantly moist by capillary attraction, is formed by a process in which the porous surface is built up upon a web of material such as water soluble polyvinyl alcohol which is removed after the printing-surface is formed by moulding. A mixture of finely comminuted rubber or rubber substitute such as a butadiene copolymer and a vulcanizing ingredient the particles of which can pass through a screen of 325 mesh to the inch, is mixed with a filler such as sodium nitrate the volume of which is 45 per cent. of the total volume of the mixture. Other fillers such as powdered metals, sodium carbonate, ammonium sulphate, or watersoluble poly-vinyl alcohol may be used. The mixture is dissolved in a volatile solvent such as methyl-ethyl ketone and applied to the web of polyvinyl alcohol to form a coating .02 inches thick. The uncoated side of the web is then placed on a thermo-setting matrix, and a similar mixture of rubber and filler but of coarser grain capable of passing a screen of 25 to 100 mesh to the inch is applied to the layer of finer mesh and the whole mass in the mould is compressed to a pressure of 250 to 6,000 lbs. per square inch, and is vulcanized at 307‹F. in or out of the mould. The backing web is then removed by washing or stripping, and the filler medium washed out in a solvent such as hot water or acid. In Fig. 1 the moulded plate is illustrated and comprises a layer 10 of a fine porous surface formed with a printing design 15, and a layer 11 of courser pores. The layers 10, 11 are soaked in ink at a temperature above 100‹C. The layer 11 may have a third layer 12 of fabric, felt, ribbon, blotting paper or a porous plate bonded thereto in the mould, and a wick 13 may keep the printing-surface supplied with ink. The printing-plate is claimed in Specification 582,475.

IPC: C01B17/04
Filed: 1972-03-27
Abstract: 1384095 Preparation of hydrogen sulphide SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 27 March 1972 [29 March 1971] 14262/72 Heading C1A The total sulphur content of Claus off-gases is decreased by passing them at a temperature above 175‹ C. together with hydrogen and carbon monoxide, over a Group VI and/or a Group VIII metal catalyst supported on an inorganic, oxidic carrier to reduce the sulphur dioxide to hydrogen sulphide and the off-gases thus treated are subsequently contacted with an adsorbent or absorbent to remove the hydrogen sulphide produced, the quantity of hydrogen and/or carbon monoxide required for the reduction being already present in the Claus off-gas by the addition of hydrocarbons and/or carbon dioxide to the Claus process from which the off-gases originate. The catalyst may contain molybdenum, tungsten and/or chromium as Group VI metal and/or a metal from the iron group as Group VIII metal. Suitable inorganic oxidic carriers include alumina and the Group VI and/or Group VIII metal catalyst may be used in sulphided form. After or simultaneously with the reduction, the off-gases may be contacted at a temperature of between 200‹ and 350‹ C. with a solid catalyst for the conversion of carbonyl sulphide and/or carbon disulphide into hydrogen sulphide. Suitable catalysts for the conversion of carbonyl sulphide and/or carbon disulphide into hydrogen sulphide include alumina, bauxite, activated clays, aluminium phosphate, thoria and magnesium chloride. The absorbent for the H 2 S produced may be solid (e.g. active carbon), or liquid such as an amine, heterocyclic base or alkanolamine. Additional oxidants or catalysts as listed in the Specification may be incorporated in the absorbent.

Title: Speed modulating arrangement
IPC: B41J1/20
Filed: 1973-03-26
Abstract: 1424764 Automatic control of speed COMPAGNIE HONEYWELL BULL 26 March 1973 [29 March 1972] 14380/73 Heading G3R [Also in Division H2] A D.C. motor mechanically connected to a rotating load through a torsion bar is fed with both D.C. and a pulsed current having a repetition rate corresponding to the natural resonant frequency of the load and torsion bar system, the respective amplitudes of the two currents being controlled so that the speed of the load periodically falls to zero. As shown in Fig. 5a, 31 is the load and 33 the motor linked by torsion bar 32. When current supplied to the motor is periodically reversed at the resonant frequency of the system mechanical oscillations will be generated having an amplitude dependent on the maximum current supplied. When the above system is used to drive the type carrier 1 in a printing machine a control system, Fig. 10, is used, in which the output of tachometer 91 is fed into two circuits, one, a peak detector and filter 92 from which is obtained a signal SVM proportional to the velocity modulation and the other a low pass filter 93 giving an output signal SV proportional to the mean velocity. Signal SV is fed into two comparators 94A,94B and is compared in one with the modulation signal SVM and in the other with a mean velocity reference signal SVR. The output signals E 1 , E2 from the comparators are used to control a D.C. current source 95B and a pulse current source 95A respectively. Pulses from a voltage/frequency converter 96 have a frequency proportional to the mean  speed of the carrier 1 and are fed through a phase converter 99A to control the frequency of pulse generator 95A. The phase converter is controlled by an error signal from comparator 94C which represents the positional error of the type carrier with respect to the hammers.  In a further embodiment Fig. 11 (not shown) the amplitude of the oscillatory movement of the type carrier is detected and compared with a reference signal (SP), which is a constant determined by the spacing of the hammers, the error signal being used to control the pulse current source. A number of methods of arranging the mechanical drive are suggested Figs. 7a-7e (not shown) in some of which two motors are used, one of which may be asynchronous and supplied from an A.C. source.

Patent GB-311341-A (GB)
Title: Improvements in and relating to dynamo-electric machine windings
IPC: H02K3/28
Filed: 1929-05-09
Abstract: 311,341. British Thomson-Houston Co., Ltd., (Assignees of Chase, D. D.). May 9, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Windings.-The armature winding of a dynamo electric machine .consists of a number of independent circuits with the coil sides of the different circuits interspersed in different slots. The circuits may be wound for different voltages or numbers of phases or may be operated independently or connected in parallel if they are exactly similar. The invention is particularly applicable in the case of a synchronous alternating current generator, the. winding of which comprises two parts or circuits, which can supply equal or unequal loads to different external circuits, the parts being magnetically coupled in a manner to introduce reactance between the separate circuits and permit power to flow therebetween within safe operating limits. Fig. 1 shows a two layer lap winding for a two pole, two circuit, threephase alternator. The winding coils are shown as having a fractional pitch and the three phases of one are A1-A4, A2-A5 and A3-A6, while the three phases of the other circuits are B1-B4, B2-B5 and B3-B6. The common terminals A4, A5, A6 and B4, B5, B6 may be arranged to connect the winding parts in star or delta. The winding parts A and B are located in alternate slots, and in order to avoid the effect of the two voltages being out of phase by an angle corresponding to one slot pitch, the lead of the circuits is alternated in adjacent phase belts. For example, as shown in Fig. 2 which shows phase A2-A5 of one winding and phase B2-B5 of the other, the coil sides of the two circuits are arranged in alternate slots, but whereas the first slot 9 in the phase belt in the centre of the Figure is occupied by a, coil side of circuit A, the first slot 21 in the succeeding phase belt is occupied by a coil side of circuit B. Instead of disposing the sides of the two winding parts in alternate slots, two coil sides of one part located in adjacent slots may be succeeded by two coils of another circuit of corresponding phase in the next two adjacent slots. In the case of machines having a number of poles greater than two the leads of the circuits in adjacent phase belts may be varied, for example, one circuit may lead under two poles, or lag under two succeeding poles. The machine may be used to interconnect bus sections of bus-bar systems in generating or sub-stations or it may be used as a synchronous motor, starting being effected with one winding only or with both windings in series.

King-pin jaws 38 pivoted at 40, Fig. 2, are releasably locked in place by a yoke 42 retractable to the right against a spring 44 by movement of a slide plate 46 having a cam slot 48 engaged with a follower 50 on the yoke. A pair of hollow levers 54 pivotally mounted at 60 by torsion rubber bushings to the underside of the fifth wheel plate 28 provide anchorages for air bag springs 74, see also Fig. 7 (not shown). The bags are inflated by an air line 86, Figs. 8 and 9 (not shown) directly or via the hollow levers through an opening 84, Fig. 7. The levers 54 are also trunnion mounted on blocks 90, and a U-shaped tie 112 depends from each side of the plate 28 and encircles a rubber washer or bumper 110, see also Fig. 4 (not shown) thus limiting relative movements between the plate 28 and the levers 54. The apparatus is not limited to the use of air springs 74 but would employ other types of springing. Figs. 10, 11 (not shown) illustrate a height control valve 120 and its linkage interposed in an air line 86, the valve controlling the amount of air in the springs 74 as the load varies during operation and uncoupling.
