Abstract: 522,143. Closing paper containers. JAGENBERG WERKE AKT.-GES. March 10, 1939, No. 7809. Convention date, May 23, 1938. [Class 94 (i)] In closing paper containers, which may be as described, in Specification 374,757, the upper ends of the walls are flattened and turned over at right angles, and compressed transversely to the axis of the vessel to form a reinforcing rib. As shown, the top is flattened and folded over as in Fig. 2, and introduced between discs 10, 11, Fig. 7. The die 10 is fixed and the die 11 is advanced towards it to engage the lower part of the double fold. The die 11 is spring held in relation to a jaw 12, which continues its advance so that an abutment z turns the top part of the fold at right angles. A die 16 advances and compresses the fold into the form shown. The faces x, y are inclined to prevent material from being forced downwards. The dimensions are such that the vertical thickness of the rib is greater than that of the part held between the dies 10, 11. If the containers are of paraffin paper, the jaws may be heated. The containers may be such as are described in Specification 521,530.

Abstract: Fine grain photographic developers are manufactured by combining p-phenylenediamine with an o-dihydroxybenzene, substituted or not, or a substituted p-dihydroxybenzene, by bringing together aqueous solutions of the components in the presence of a reducing agent of acidic character.  In an example, p-phenylenediamine is dissolved in sodium bisulphite solution, treated with decolourizing charcoal, filtered hot, and mixed with a hot solution of pyrocatechin in potassium metabisulphite solution.  The pyrocatechin may be replaced by pyrogallol or chloroquinol.  Specification 466,625, [Group XX], is referred to.

[Class 75 (i)] A crude oil burner comprises an annular vaporising pan 12 having a bottom sloping from a ridge 35 to a sump 30 and fitting closely on the bevelled upper edge of a lower pan 18, a cover 8 for the pan 12 having an upward extension 7 forming with the pan wall 25 a vapour outlet slit 9, and a jacket 26 for preheating the air entering the burner through tangential slots 15 in the lower edge of the pan 12 and through holes 23, 24 in the pan wall 25. At starting the pan 18 is turned by a handle 33 to cause a slight gap between the pans 12, 18 by the engagement of inclined parts 36, 37 of their contacting surfaces and oil is supplied to the inlet 28 of the pan 12 through a pipe bent to prevent the entrance of air. This oil overflows into the pan 18 at a hole 31 in the sump 30 and is there ignited by a match thrown through the gap between the pans. The flame ascends to the chimney 1 through the aperture 29 in the pan 12 and around a heat-conducting column 27. Vaporisation of the oil in the pan 12 is thereby effected and this vapour passes through the slit 9 to burn with air entering through the holes 29, 24, whirling of the flames being caused by inclined vanes 4, 19 on the cover 8 and pan 12 respectively. The pan 18 is then turned back to its original position sufficient air for the combustion of the reduced quantity of oil reaching the pan 18 entering through the slots 15. The lower surface of the pan is covered with heat insulating material 34 protected by a plate 20.

Title: Improvements in after-treatment of vinylidene cyanide interpolymers
IPC: C08F8/00
Filed: 1957-03-14
Abstract: Interpolymers are prepared from a mixture containing vinylidene cyanide and a minor proportion of b -methylene-b -propiolactone, and then treated with a compound containing active hydrogen to open the lactone rings and produce dye-receptive groups in the polymers.  The monomer mixture may contain a third ingredient, e.g. vinyl acetate. Substances mentioned for cleaving the lactone ring are ammonia, aliphatic or aromatic amines, phenols, alcohols, hydrogen sulphide, thiols, hydrogen chloride, sulphuric acid, phosphoric acid, phosphinic acid, acetylene, malonic acid or its esters and acetoacetic ester.  Polymerization may be effected in solvents, e.g. benzene, toluene, xylene, chlorbenzene or nitrobenzene with a free radical catalyst at - 15 DEG  to 100 DEG  C., by heating in a non-solvent for the vinylidene cyanide, e.g. hexane or heptane, or simply by agitating the mixed monomers with a catalyst.  Catalysts mentioned are per-compounds, e.g. peroxides, perborates or percarbonates, or compounds such as a ,a 1-azodiisobutyronitrile, a ,a 1-azo-bis-(a ,b -dimethylbutyronitrile) and a ,a 1-azobis-(a -cyclo-propionitrile).  The interpolymers are soluble, e.g. in dimethylformamide, dimethyl sulphoxide, nitromethane, acetonitrile or tetramethyl urea, and shaped articles, e.g. rods, fibres or films may be formed from the solutions.  In the examples interpolymers are prepared from vinylidene cyanide on b -methylene-b -propiolactone with or without comparatively large amounts of vinyl acetate, the interpolymers are dissolved, treated with : I, hexamethylene diamine; II, phosphoric acid; III, methyl amine; IV, 2-(2-aminoethylamino)-ethanol, monoethanolamine, tetraethylenepentamine or ethylene imine; V and VII 2-(2-aminoethylamino)-ethanol; VI, hexamethylene diamine or ethanolamine.  Films or fibres prepared from the treated solutions were dyed with different dyestuffs.  Untreated interpolymers or treated interpolymers which did not contain the lactone rings could not be dyed.  Specifications 681,120, 683,655, 685,016, 688,339, 726,068, 726,269, 726,863 and 726,866 are referred to.

In an automatic pilot in which an error signal is a sinusoidal function of error, a signal derived from the error signal is added to the error signal to linearize it. In an instrument landing system for an aircraft, the output of a radio receiver, which is dependent on displacement of the aircraft from a localizer radio beam, is applied through a computer to amplifiers respectively controlling a servo-operated rudder and servo-operated ailerons to maintain the aircraft on the beam. A follow-up motor, which takes up a position corresponding to the heading of the aircraft as determined by the output of an earth inductor compass, drives a signal generator developing an A.C. heading error signal. This signal, the magnitude of which is a sinusoidal function of the error is rectified and applied to control the control grid and suppressor grid potentials of a pentode valve amplifying a portion of the error signal to produce a component which when added to the original error signal produces for application to the computer a signal the magnitude of which varies linearly with the error.

Plunger 52 bears on lever 64 supported at one end on adjustable pivot 62 and bearing at its other end on contact actuating button 12. Turning member 8 turns spindle 10 which in one direction, clockwise looking at Fig. 2, rotates cam 22 which pivots lever 32 about pivot 30 to depress stud 40a, stud-head 40, one of plates 42 and plunger 52. A second cam (24), Fig. 5 (not shown) is mounted on spindle 10 at its other end and clockwise rotation of spindle 10 brings cam (24) against pivot 30 or that cam (24) cannot move. Rotation of spindle 10 anticlockwise looking at Fig. 2 causes spindle 10 to rotate in cam 22 until flat 10a on spindle 10 engages nib 22d on cam 22 which urges cam 22 against pivot 30 so that cam 22 cannot move but cam (24) can rotate pivoting lever (34), Fig. 5 (not shown) depressing stud 38, which is similar to stud 40a and stud head 40, to depress the top upper trifurcated plate 42 shown in Fig. 3 to depress plunger 52. Plunger 52 is depressed by the upper or lower plates 42 acting on flange 52a of plunger 52. Plunger 52 is located on a peg 54 the lower part of which is square and the upper part round, the outer arms 42b of plates 42 fitting on one side of flange 52a to retain plunger 52 in sub-assembly 2 and the central arms 42a of plates 42 engaging the other side of flange 52a to depress it. Lifting plunger 52 clear of the square part of peg 54 and rotating it enables flange 52a to be engaged by one or both of plates 42 or that plunger 52 is depressed by rotating member 8 in one direction only or the other only or both. There is a retractive spiral spring (28), Fig. 5, round spindle 10. A sealing gasket 44 terminating in ends 44a is between the two housings 2a and 4a, and there is a sealing gasket 58 round spindle 10 where it leaves housing 2a, gasket 58 forming a pocket, Fig. 4 (not shown) so that liquid attempting to enter tightens the seal provided by gasket 58.
