Title: Improvements in or relating to epoxy resins
Inventor: HOLLOWAY MAURICE WILLIAM
IPC: C08G59/52
Filed: 1966-04-20
Abstract: 1,141,206. Aniline derivatives. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 8 May, 1967 [20 April, 1966], No. 17382/66. Heading C2C. [Also in Division C3] The Specification discloses the preparation of aminophenoxy compounds, aminophenylamide compounds, aminophenylurethane compounds, aminobenzoate compounds and aminophenyl compounds. The aminophenoxy compounds are prepared by reacting the appropriate di- or tri-bromo compound (1À5 or 1 mole) with 3 moles of the potassium salt of 3- or 4- nitrophenol in dimethylformamide under reflux. The nitrophenoxy precursor compound is isolated by pouring into water followed by recrystallization from acetone. This is subsequently reduced with paleadized charcoal and hydrazine hydrate. The solid amines are recrystallized from a hydroxylic solvent and the liquid amines by distillation. Compounds prepared are (1) 1,5 - bis - (4 - aminophenoxy)- pentane; (2) 1,10 - bis - (3 - aminophenoxy) - decane; (3) bis - (3 - aminophenoxy derivative) of polyethylene glycol (M.W. 300) and 1,2 - bis - (2 - (3 - aminophenoxy) - ethoxy) - ethane. Examples of aminophenylamide compounds are: (1) N,N<SP>1</SP> - bis - (3 - aminophenyl) - sebacamide; and (2) N,N-dimethyl-N,N<SP>1</SP> - bis - (3 - aminophenyl) - sebacamide. These are prepared by first reacting the acid chloride of the dibasic acid with a nitroaniline or an N- substituted nitroaniline followed by reduction as previously described. Aminophenylurethane compounds are prepared by reacting an aromatic diisocyanate with a di- or tri-hydroxy compound to give an isocyanatophenylurethane compound which is subsequently hydrolysed to the corresponding amine with conc. HC1. The example described is the bis-aminotolylurethane derivative of polyethylene glycol (M.W. 300). The aminobenzoates are prepared by reacting the appropriate diol or triol with 3- or 4-nitrobenzoyl chloride. The nitroprecursor obtained is then reduced to the corresponding amine. Triethylene glycol bis- (4 - aminobenzoate) is a typical example. The only aminophenyl compound disclosed is 1,6 - bis - (4 - aminophenyl) - hexane. This is prepared from a Grignard reagent of #-phenylpropylbromide (3 moles) and hydrocinnamaldehyde (2.5 moles). This gives 1,6-diphenylhexan-3-ol which is distilled through an alumina tube at 350‹ C. to give 1,6-diphenyl-hex- 3-ene. Catalytic hydrogenation of this compound followed by nitration and reduction gives the desired diamine.

Title: Electric regulators
IPC: H02P25/10
Filed: 1927-07-06
Abstract: 275,582. Electrical Research Products, Inc., (Assignees of Stoller, H. M., and Morton, E. R.). Aug. 4, 1926, [Convention date]. Regulation, automatic. - For automatically regulating speed or frequency of a dynamoelectric machine, a thermionic valve is arranged so that the grid potential changes responsively to changes of speed, the anode current being amplified and used electromagnetically to change the voltage of supply in a compensatory sense. The Figure shows an arrangement for maintaining constant speed of an alternating current repulsion motor 5 supplied from mains 6 through a transformer 9. A high frequency induction type generator 11 driven by the motor feeds a tuned circuit containing an inductance coil 19 the ends of which are connected to the grid and filament of a thermionic valve 15. Change of the grid potential due to change of speed of the motor varies the anode current of the valve, which, after being amplified and rectified by two valves 16, 17, excites a direct current winding 10 of a variable inductance device 7 connected in the feeding line of the motor 5. The arrangement is such that increase of speed brings about increase of inductance and consequently decreased effective feed voltage. To obviate hunting action the anode circuit and the grid circuit of the responsive valve 15 are interlinked through a transformer 28. Specifications 275,784 and 297,153 are referred to.

Patent GB-744687-A (GB)
Title: Improvements in or relating to fluidized hydroforming process
IPC: C10G35/14
Filed: 1953-06-30
Abstract: <PICT:0744687/III/1> In a hydroforming process wherein hydrocarbon fractions are contacted with a dense fluidized catalyst which is continually withdrawn and regenerated in a fluidized state whereby carbonaceous deposits are burnt therefrom, the spent catalyst particles are maintained under regenerative conditions in the regeneration zone for at least 35 minutes and preferably for 1 to 5 hours.  The extended regeneration time can be achieved by enlarging the regenerator to increase holding time or by using a plate column regenerator wherein spent catalyst is supplied to the top of the column and passed via downcomers from plate to plate countercurrent to the regenerating gas which is supplied below the lowest plate at such a velocity as to maintain a dense fluidized bed of catalyst on each plate.  Cooling coils may be provided at one or more of the plates to control the temperature. In an alternative regenerator, Fig. 2, spent catalyst suspended in air or other carrier gas is introduced through cone 112 into the upper zone of regenerator vessel 110, the remainder of the regeneration gas being introduced via nozzles in the vicinity of 112 and through distribution cone 115 at a velocity, e.g. 0.6-1.0 ft. per second, sufficient to form a dense fluidized bed of catalyst 116 in said upper zone.  The average time of residence in this upper zone is less than 15 minutes and may be as little as 3-5 minutes.  The portion of the regenerator below 112 is a low velocity zone, provided with baffles 123 and 124, through which the velocity of regeneration gas is sufficient only to maintain fluidity so as to ensure countercurrent contact between gas and catalyst, and wherein the catalyst is maintained in contact with the said gas for at least 35 minutes.  The regeneration temperature in the upper zone may be controlled by passing water or other heat-exchange fluid through cooling jacket 130. Alternatively an arrangement of cooling coils with a primary coil entirely below the dense bed level and a secondary coil partly above and partly below, may be used, permitting adjustment of heat-exchange by variation of bed level.  The regenerator is operated at 50-500 lbs. per sq. inch pressure and at temperatures of 1050-1200 DEG F. preferably 1075-1125 DEG F.  The regeneration gas may be air but air diluted with flue gas to 1 to 5 per cent O2 concentration is preferred.  Suitable catalysts include Group VI metal oxides such as molybdenum, chromium or tungsten oxide, or mixtures thereof, preferably supported on activated alumina or zinc spinel.  Minor amounts of promoters such as silica, calcium oxide, ceria or potassium oxide may be included in the catalyst.

Title: Boring or drilling and like machine tools
IPC: B23Q5/32
Filed: 1940-12-24
Abstract: 543,878. Boring and drilling. TURRETTINI, F. Dec. 24, 1940, No. 18109. [Class 83 (iii)] To give a quick return motion to the spindle 2 of a boring or drilling machine, the quill 4 in which it is mounted is driven by a rack and pinion 6 from a worm and worm-wheel 8 which is coupled to the hollow shaft 11 of the pinion 6 for a slow drive. The coupling comprises a spring plunger 9 engaging a hole in a disc 10 which is keyed to the shaft 11 at 12. The disc 10 can be moved by a bar 13 actuated by hand levers 31 to clutch the shaft 11 to the worm-wheel 8 to start the slow speed drive, and the return motion is started by energizing an electric motor which drives a worm 15 and at the same time a switch is operated to energize an electromagnet 21. The worm 15 drives a worm-wheel 16 free on the shaft 11 and when the wheel 16 rotates it is caused to move to the left by the action of balls 17 in a cage 18 on inclined grooves 16a, 19a in wheels 16, 19 both free on the shaft 11. The movement of wheel 16 to the left actuates a pin 20 to displace the disc 10 and so declutch the slow drive, and the balls transmit the fast drive to the wheel 19 which drives a wheel 24, and this wheel is clutched to a wheel 26 by the energization of the electromagnet and the wheel 26 drives a wheel 27 keyed to the shaft 11 at a speed which is the reverse of and greater than the original speed. A switch is operated to de-energize the magnet 21 when the tool has been withdrawn fully.
