Abstract: 832,129. Levelling coke oven charges. KOPPERS G.m.b.H., H. March 4, 1958 [March 4, 1957], No. 6995/58. Class 51 (2). An open-topped trough 13, of shape and size corresponding to the levelling bar opening 4 of a coke oven door 2, surrounds the leveller bar 5 mounted between rollers 6 on a coke pusher machine. Coal dropping out of the oven during levelling is taken from the bottom outlet of a collector 8 to an outlet 11 above the leveller bar 5 by a chain conveyer 10. The trough 13, guided by T-section pieces secured to reinforcing side pieces 14 and engaging slots between angle-irons fastened to members 18 on each side of the frame of the coke pusher machine, is axially displaceable on the pusher machine and is urged against the leveller bar opening 4 by the action of counterweight 28 through linkage 25, 24 on draw rods 20 running between roller guides 22 on the members 18. A draw cable 29 enables the trough 13 to be withdrawn. The length of the trough 13 is sufficient for the coal falling from the outlet 11 above the leveller bar 5 to fall into the trough to be returned to the oven by the leveller bar. A shoot 31 pivoted to the oven end of the trough 13 hangs vertically when the trough is withdrawn, but when the trough engages the door 2, the lower end of the shoot engages the wall of collector 8, to close any gap between the coke oven door 2 and the trough 13.
Patent GB-621044-A (GB)
Title: Improvements in or relating to synthetic resinous compositions
IPC: C08G14/06
Filed: 1946-03-06
Abstract: Synthetic resins are prepared by reacting an aminodiphenyl or an aminodiphenylmethane, each having one amino group on either or both of the phenolic nuclei with an aldehyde, e.g. formaldehyde, acetaldehyde or benzaldehyde and incorporating with the product 10-20 per cent of its weight of an acid-catalysed novolak resin. If desired, phenol, aminodiphenyl and formaldehyde may be simultaneously reacted together in presence of an acid catalyst. The amino body may be reacted with sufficient aldehyde to form a product incompatible with a novolak and then further reacted with phenol to yield a product which is compatible.  The products may be mixed with fillers, hardening agents, lime, mould lubricant and a pigment to yield moulding powders suitable for making high-frequency electrical insulation with good moisture resistance.  Suitable fillers are mica, amphibole, asbestos, or alumina.  In the examples: (1) mono-o-aminodiphenyl is reacted with formaldehyde, in the presence of an acid catalyst, and the produce heated with a novolak to yield a brittle resin which becomes heat hardening with the addition of hexa-methylene-tetramine; (2) mono-o-aminodiphenyl and formaldehyde are refluxed in the presence of concentrated hydrochloric acid, the product dehydrated under vacuum and heated with a novolak resin; (3) phenol, mono-o-amino-diphenyl and formaldehyde were reacted in the presence of concentrated hydrochloric acid; (4) mono - para - aminodiphenyl - formaldehyde condensation product prepared with concentrated hydrochloric acid was reacted with novolak resin as in example (2); (5) 4,41-diaminodiphenyl - formaldehyde condensation product was prepared in the presence of concentrated hydrochloric acid and excess formaldehyde.  The product was reacted with phenol to yield a complex compatible with a novolak resin; (6) a condensate of 4,41-diaminodiphenyl methane with formaldehyde was prepared as in example (5) and was reacted with excess phenol to yield a product compatible with novolak.  Moulding materials were prepared from the products of the examples mixed with 10 per cent hexamethylene tetramine, lime or lubricant, and powdered mica and moulded pieces were prepared which were tested for electrical properties and compared with resins containing anhydro-formaldehyde-aniline.  The properties of moulded products from powders containing 3 and 6 per cent hexamethylenetetramine are also given and composed with those of products of unmodified novolak resins and of anhydro-formaldehyde-aniline modified novolaks.  The Specification as open to inspection under Sect. 91 covers the use of the amines per se as additions to novolak resins.  This subject-matter does not appear in the Specification as accepted.

Title: Improved method of mounting hinged doors
IPC: E05D3/10
Filed: 1932-03-11
Abstract: 394,767. Hinges. PRESSED STEEL CO. OF GREAT BRITAIN, Ltd., Cowley, Oxford, and FERNBERG, E. B., 11, The Drive, Edgware, Middlesex. March 11, 1932, No. 7375. [Classes 65 (i) and 65 (ii).] In a door mounted on hinges of the kind comprising two members hinged together and each hinged to an attachment plate, the hinges are so constructed that the angles between the axes of the joints of each hinge (when opened out flat) are different from those of the other hinges, so that the tendency to distortion under the weight of the door is different for each hinge and these tendencies will nullify one another. One of the hinges is shown opened out flat in Fig. 4, and comprises two parts 10 hinged together about.an axis 12, each part 10 being hinged to an attachment plate 9 about an axis 11 ; the three axes intersect in a common point which lies on the axis of rotation of the door, and the axis 12 bisects the angle between the axes 11 or, in the case when the axes 11 coincide, the axis 12 is at right angles to the axes 11. Fig. 1 shows a door mounted on three hinges having different angles between their axes 11, 12. The door and door-post, of pressed sheet steel, are formed with recesses 21 in which the hinges are fixed and which receive the leaves 10 when the door is closed. The maximum opening of the door is affected both by the angle between the axes of any hinge and by the angle which the outer axes of the hinge make with the horizontal when fixed ; the hinges are preferably set at different angles, according to the angle between their axes, so that the load is shared equally between them when the door is open. One or more of the hinges may be mounted with the leaves 10 projecting upwardly. One or more hinges of the ordinary type may be used in conjunction with these hinges. Stops may be provided at one or more of the axes of any of the hinges to limit the extent of opening. In order to impart a rising movement to the door on opening, so that it closes under its own weight, the middle leaves 10 of the hinges are made of different lengths ; the axis 12 does not then pass through the intersection of axes 11, but is parallel to the bisector of the angle between axes 11 or, if axes 11 are coincident, it is perpendicular to them.
