Filed: 1929-12-05
Abstract: 337,254. De Gaillard et Cie, H. Feb. 16, 1929, [Convention date]. Regenerators and regenerative fittings.-The chequer work of a hot blast stove &c. is composed of a, stack of tubes g of regular or irregular hexagonal shape, the tubes having a bearing against each other, in the direction of maximum strain, on two opposite sides and. along two edges, and having bye-pass apertures k into the passages h between them. Such passages have a cross-sectional area at least equal to the bores of the tubes. Different directions of bearing contact e.g. o-w, o<1>-w, Fig. 5, are obtained by using a set of hexagonal junction tubes contacting on all sides. The tubes are supported by members l resting on small girders m, lines of such members being connected by cross-bars, p.

Abstract: 523,040. Typewriters. ROYAL TYPEWRITER CO., Inc. Dec. 22, 1938, No. 37389. Convention date, Dec. 30, 1937. [Class 100 (iv)] Keys.-For varying the touch of the type actions the anchor plate 20, to which all the action springs 27 are attached, is movable under the control of a handwheel 32 which projects through a slot 41 in a coverplate 40 fitted in an opening in one of the side frames 6 of the machine. The side plates enclose and mask from view the type actions 7-19. The wheel 32 is attached to the shaft of a worm 31 which actuates a worm wheel 33 on a shaft 34 to which is fitted an upwardly extending arm 35, Figs. 1 and 3. to which is connected a link 32 attached to an extension of the anchor plate 20. Movement of the arm 35 thus actuates the plate 20 and controls the tension of the springs 27, the action of which on the plate 20 is balanced by an adjustable counter spring 47. The arm 35 is bent as shown in Fig. 3, to form an upper arm 36 which acts as a pointer and moves behind an arcual slot 42 in the plate 40, which is fitted with a transparent cover and is graduated so that an observer who actuates the wheel 32 can readily view the extent of adjustment by watching the pointer 36. The shaft 34 is mounted in a bracket 28, and its movement is limited by a stop 51. Specification 466,136 is referred to.

Title: Production of high carbon pitches and pitch compositions
IPC: C10C1/16
Filed: 1928-12-27
Abstract: 303,163. Barrett Co., (Assignees of Miller, S. P.). Dec. 29, 1927, [Convention date]. Condensing processes; pitch.-In coke oven or gas retort plant the ovens 5 are connected to valve boxes 7 communicating with collector mains 8, 9, into one or other of which the gases are directed by means of valves 10 according to the stage of distillation. " Rich " and " lean gases are thus collected separately in the mains and cooled by ammonia liquor sprays 11. Tarry oil constituents are separated from the gases which are then treated in plant for extraction of ammonia and light oils. Tar condensing in the collector mains is separated from ammonia liquor and that from the " lean " gas mains, possessing a relatively high free carbon content, is pumped into a short main or still 31 connected to a number of ovens. The tar is atomized into the hot gas stream by a rotating cylinder 34 or other means and is distilled. pitch being withdrawn at an outlet 36. Volatile constituents pass with the scrubbed gas through a settling tower 46. which may contain packing, to a condenser. To prepare composite products of intermediate carbon content and melting point the high carbon pitch may be blended with various kinds of tar or a lower melting point pitch. The hot pitch may be supplied to a chamber 41 in a stream caused to intermingle with a stream of tar &c. Vaporized oil is led to a condenser 45. The tar employed may .be previously subjected to partial distillation to dehydrate it or free it from lower boiling point oils. Tars of a lighter character than that obtained in the collector main may be separated in the cross-over mains and condensers and these may also be distilled providing a relatively large proportion of oil and a small amount of pitch. Specifications 289,378, 303,164, and 303,165 are referred to.

In Fig. 1 fibre web 5 is unwound from supply roll 4 and deposited onto film 2 which is pulled over table 3 where the fibre web is impregnated with hardenable resin by means of applicator 6. A second film 8 is then deposited on to the impregnated fibre layer and the laminate passed through squeeze rollers 9 and then through oven 10 where it is given an undulated or other shape, and heated to gel the resin. The upper cover 8 is then peeled off and wound onto roll 11 and the impregnated fibre layer coated with resin by means of applicator 12, e.g. by spraying or by means of a wiper, and curing effected in oven 13. If desired the laminate may then be inverted and the film 2 removed to permit the application of another resin layer to the other surface of the resin impregnated fibre layer. The resin used for the protective layer may be the same as or different from that used to impregnate the fibre layer. The protective layer, which may be applied in the liquid or gel state, may comprise acrylic or polyurethane resins and metallic gloss effect lacquers.
