Filed: 1920-04-26
Abstract: 142,467. Goodyear Tire & Rubber Co., (Assignees of Upson, R. H.). May 1, 1919, [Convention date]. Steering and balancing.-Means for automatically counteracting the directional instability of aircraft comprise a subsidiary vane mounted on a vertical pivot on the rudder, and so connected to the rudder that the action of lateral wind pressure on the vane tends to turn the rudder in the direction required to counteract the yawing of the craft which has produced, or is the result of, the lateral pressure. The vane is adjustable by the pilot for use as a relay device to produce a corresponding adjustment of the rudder. Similar, but horizonta.l, vanes may be used in connexion with the elevators for counteracting pitching. The invention is stated to be applicable to heavier.-than-air craft, captive balloons, boats, submarines, &c. Figs. 1 and 2 show a vertical vane 17 pivoted in extensions 16 carried by the forward portion 14 of the rudder 12 pivoted at 15 to the fixed fin 11, the pivots of the vane and rudder being in front of their centres of pressure. An arm 19 carried by the vane is connected by cords 20 to an arm 18 pivoted under the hinge 15 and normally fixed on the air-ship, but adjustable relatively thereto by means of control wires 21. Lateral wind pressure produces a displacement of the vane and rudder, as indicated in dotted lines in Fig. 2; or adjustment of the arms 18 and vane 17 effects a corresponding adjustment of the rudder. The rudder may further be operated by the usual control wires 22, as shown in Fig. 3, which, however, illustrates a modified form of vane 24, which is hinged at 25 to the rudder and provided with a slide 26 free to move along a rod 27.

Patent GB-357168-A (GB)
Title: A process for the production of slabs from fibrous material
IPC: C04B28/02
Filed: 1930-04-14
Abstract: 357,168. Moulding insulating slabs containing wood wool. PLETSCHER, E., 19, Grendel, Lucerne, Switzerland. April 14, 1930, No. 11711. Convention date, April 14, 1929. [Classes 70 and 87 (ii).] In a process for the production of insulating slabs from wood wool and air-hardening cementitious material a mass of wood wool, without previous impregnation with chemicals, is first moistened with water by dipping, then has just sufficient dry hydraulic cement and/or gypsum sprinkled or dusted on it to coat the wood wool with a thin film of the cementitious material, whereafter the mass is stirred and finally laid in a mould to harden under moderate pressure. Various kinds of hydraulic cement, such as Portland cement, Grenoble cement, &c., can be used; also the gypsum can have materials added to it, such as marble dust, to make it harder. When cement is used the mass must remain somewhat longer in the mould, since the cement hardens less quickly than the gypsum. The Specification as open to inspection under Sect. 91 (3) (a) comprises also processes in which fibrous material is dipped in a mixture of the coating substance with water, taken out, allowed to drain, and placed in the moulds, or the fibrous material may be mixed with the correct quantity of the coating substance and water and the draining dispensed with. The cement may have materials, such as water glass, added to it to make it bind more quickly. A moulding machine is also described in which moulds arrive successively over a press which closes them after filling and over a machine for ejecting the finished slabs. A turntable 4, mounted on an axle 2, carries a number, for example eight, rectangular moulds 6 in a frame 5. The covers 7 of the moulds are locked by bolts and the floors 8 rest on adjustable cross members 9. A press is situated under one mould and consists of a hand-wheel 21 which extends the elbow levers 15. After the mould is filled, the cover 7 is held by the bolts 33 and the mould is raised by the press until the cover is level with its upper edge. The ejecting machine is similar to the press but has two projections on the platform 11 which raise the floor 8 of the mould. In a modification shown in Fig. 4 (Cancelled), instead of being mounted rotatably, the moulds run from the press to the ejecting machine along rails 50 and return empty along rails 51. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to web tensioning apparatus for printing or other machines
IPC: B65H23/08
Filed: 1940-07-15
Abstract: 543,300. Feeding webs. GOSS PRINTING PRESS CO., Ltd. July 15, 1940, No. 11721. Convention date, May 4. [Class 100 (i)] The tension of the web fed to a printing or other machine is controlled by a friction member pressed against the surface of the web supply roll, the friction member being anchored at one end and attached at the other end to a drum urged to rotate by a motor acting through an eddy current clutch. The friction member may comprise belts spring anchored at their lower ends and attached at their upper ends to a drum 34, Fig. 3, constantly urged to rotate by a motor 30 which, as indicated, may operate a number of drums controlling a number of webs. The motor 30 drives a shaft 31 which, through worm gear 36, 37, Fig. 2, drives a spindle 38 to which is fixed the outer element 40 of an eddy current clutch,the inner element 45 of which, carrying the winding 49, is fixed to a spindle 53 operatively connected by a sprocket pinion 62 and chain to the drum 34. The winding 49 is connected to slip rings 50, 51 against which bear brushes 60 connected to leads 109, 110. Lead 109 is connected directly to a direct current generator 104 driven from a motor 102 supplied from the mains 100 which also supply the motor 30. The other lead 110 is connected to a switch arm 119 controlling the selection of one of a number of resistances 112 .. 114 which are connected to a variable resistance 111, the switch arm of which is connected to the generator 104. The resistances 112 .. 115 are of different values and each has a number of tappings connected by spring arms 118 to contacts 116 which are normally open but adapted to be pressed together sequentially to short circuit more or less of the resistance by one arm 120 of a lever 72 carrying a pilot roller 14 round which the web passes on its way to the machine. Shock absorbers 70 control the movements of the lever 72. The resistance 11 is initially adjusted manually in accordance with the width of the roll in use and the resistance 112 .. 115 is selected by means of the switch arm 119. The variation of the resistance of the selected resistance 112 .. 115 due to movements of the pilot roller 14 cause varying amount of the power of the motor 30 to be applied to the drum 34 thus keeping the tension of the web substantially constant. When the machine is slowed down or the web breaks, the decreased tension of the web causes the roller 14 to move to the left in Fig. 3 short curcuiting much or all of the selected resistance 112 .. 115 increasing the current to the clutch and thus applying a greatly increased pressure to the brake belts.

IPC: D02G3/00
Filed: 1927-05-04
Abstract: 270,727. Bonnard, G. May 10, 1926, [Convention date]. Degumming silk.-In the production of chappe yarn from silk crape waste, the material is broken up into shorter threads in a waste opener, the threads are then separated into parallel lines in a carding machine or in a set of carders in which the filaments are broken further. The sliver is then cut up if necessary into lengths to ensure the freeing of ends of filaments, and to obtain a length of filament of 4 centimetres or upwards. The mass is then treated in boiling water (to which a little soap may be added) for about 30-40 minutes, the filaments being kept in motion to facilitate untwisting thereof and to avoid the formation of compact masses. The material is then rinsed and dried, and consists of a somewhat short staple chappe which may be carded, combed, drawn and spun with or without admixture with other fibres such as wool to form a mixed yarn. Wool crape waste may be similarly treated.
