Filed: 1926-07-21
Abstract: 262,671. Golland, H. S. July 21, 1926. Mules.-In an arrangement of the kind described in Specifications 230,368 and 238,804 for cross-winding yarn in mules, in which the operating-mechanism is carried by short shafts supported in brackets mounted on the mule carriage, the short shafts b, Fig. 1, are also supported from the winding-faller shaft c by pendent brackets b<1> and the movements of the shaft c are communicated to the mechanism through a lever e and link e<1>. The link e<1> is connected to a plate f loose on the shaft b, and carrying a disc h with teeth h<1> adapted to mesh with teeth g<1> out in a disc g fixed to one of the supporting brackets a and loose on the shaft b. The disc h also carries a cam h<2> engaging a bowl i<1> on a loose plate i, carrying a pinion engaging teeth g<2> on the disc g. The pinion j turns on the stud k<1> with the ratchet j<1>, Fig. 2, and draws wound a pawl o and the plate k on which it is mounted. A pin k<3> on a plate l centred on the shaft b engages a slot k<2> in the plate k whereby movement is transmitted through a link m to the cross-winding shaft d and the sickles n<2> and wire n<3>. The connection between the link m and the plate l is adjustable to regulate the movement of the wire n<3> without varying the inclines on the copping-rail. During the outward run owing to the raising of the winding-faller, a member p centred at p' on the bracket a is moved by the engagement of a slot f<3> in the plate f with a pin p<2> on the member to bring the end p<3> under a bowl i<4> on the plate i to lock it in position. During backing-off the end of the link e<1> encounters a stop i<5> on the plate i and holds it in position. The cam q operated by pinions j<2>, j<3> supports the bowl q<1> on the plate k. The bowl rests in the depression in the cam during the formation of the cop-bottom and thereafter on its annular periphery. The pawl o is disengaged from the ratchet j<1> by the projection o<2> before backing-off. Specifications 22988/02, 4848/07, 1470/14, 184,386, and 195,018 also are referred to.

Patent GB-365190-A (GB)
Title: Improvements in or relating to gyroscopic systems for controlling dirigible objects such as aeroplanes
IPC: B64C1/00
Filed: 1925-07-18
Abstract: 365,190. Gyroscopic apparatus. COOKE, P. A., Royal Aircraft Establishment, South Farnborough, Hampshire. July 18, 1925, No. 18393. [Class 97 (iii).] In an automatic control system of the type in which a single universally mounted gyroscope controls both yaw and pitching movements and in which a follow-up system is employed, the gyroscope is arranged with the rotor axis in the fore and aft direction of the dirigible body and the system comprises means sensitive to the component of total acceleration along the fore and aft axis and means for applying torque determined by this component to precess the rotor axis in the longitudinal vertical plane. The invention is shewn applied to a gyro control system of the type described in Specification 365,186 having a rotor 1 either electrically driven or driven by air jets supplied with pressure air through a hollow bottom pivot of the azimuth ring 6 to which the jets are attached. Course changing means such as described in Specification 365,189 are shown at 23, Fig. 1. The inherent tendency of the pitch ring 4 to precess due to the rotation of the earth is counteracted by putting the rotor and gimbal system out of balance by a weight 40 on the azimuth ring so arranged that in unaccelerated motion there will be no couple about the azimuth axis so long as this axis is vertical. Precession of the pitch ring causes operation of the elevators and hence tilting of the azimuth axis whereby the component of gravitational acceleration acting on weight 40 exerts a couple round that axis thus precessing the pitch ring back again and applying elevator until the azimuth axis is again vertical. A lever 41, Fig. 2, pivoted on frame 8 is arranged to bear at one end on a pin 42 on the azimuth ring eccentric to its axis. The lever carries a coiled spring 43 connected so that its torque opposes the torque exerted by weight 40 when the azimuth axis is inclined backwardly. A winding arrangement 44 permits the spring torque to be varied to enable the pitch ring to be maintained in equilibrium for any desired angle of climb. A stack of aneroid diaphragms 45 is mounted on frame 8 so that when expanding it bears on to opposite end 46 of lever 41 and opposes the spring torque. The stack 45 may be adjustably anchored to frame 8 by screw and nut gear 47, 48 driven by a small air motor the air supply to which is controlled by a two-way valve. The rate of change of height then depends on the pressure of air supplied to jets which can be set by a reducing valve. The control system may be adjusted so that the craft turns with the azimuth axis vertical with the engine throttled right back by arranging that the lever 41 is lifted clear of the pin 42. Specification 365,187 also is referred to.

Filed: 1942-12-29
Abstract: 560,581. Valves; valve gear. WILKINSON, F. M. Dec. 29, 1942, No. 18440. [Class 7 (vi)] [Also in Group XXVI] Packing for a rotary spherical valve comprises two or more pairs of intersecting spring compression rings 5, 6 mounted in grooves cut in the surface of the valve and secured against rotation either by their intersection or by pegs on the rings engaging in sockets in the grooves. A large port may be lined with a bush having packing rings on its outer surface, the inner end of the bush being held by an inclined shoulder in the port and the outer end being formed with concentric lands to increase the pressure per unit area with which centrifugal force holds the bush against the valve seating. As shown in Fig. 4, an oscillatory motion is imposed on the rotation of the valve. A sleeve 21 is rotated about a stationary shaft 28, to which is keyed a bevel gear 23, by a chain and sprocket 26 and a crank-pin 25 rotatably mounted in the sleeve is keyed to the valve 27 and a bevel pinion 24 meshing with the bevel gear 23 so that rotation of the bevel pinion 24 about the. fixed gear 23 oscillates the valve and also rotates it about the axis of the crankpin 25.

Title: Improvements in or relating to the bonding of rubber to metal
Inventor: GURNEY WILLIAM ARTHUR
IPC: C08J5/12
Filed: 1954-06-23
Abstract: Natural or synthetic rubber is bonded to metal by applying to the metal surface a layer of a phenol-aldehyde resin containing a reactant for the formation of a polyhydroxyphenol-aldehyde resin, applying to the layer a vulcanizable rubber composition containing a reactant for the formation of a polyhydroxyphenol-aldehyde resin, applying to the layer a vulcanizable rubber composition containing a further reactant capable of condensing with the first reactant to form a polyhydroxy-phenol-aldehyde resin under vulcanizing conditions, or containing a compound capable of generating such a reactant, and vulcanizing the rubber composition.  The vulcanizable rubber composition containing the further reactant or generator therefor may be applied as a thin layer to the resin layer and a further layer of a vulcanizable rubber composition is applied to the thin layer prior to vulcanization.  Preferably the phenol-aldehyde resin layer contains a free poly-hydroxy-phenol, e.g. resorcinol, xylenol, or phloroglucinol, and the rubber composition contains paraformaldehyde, metaldehyde, formaldehyde, furfuraldehyde, or acetaldehyde, or a compound capable of generating an aldehyde under vulcanizing conditions, e.g. hexamethylene tetramine, or acetaldehyde-ammonia.  In an example a metal plate is coated with a solution in methyl ethyl ketone of a phenol-formaldehyde resin containing free resorcinol, and to the coating is applied a solution in ethylene dichloride of a vulcanizable rubber composition containing paraformaldehyde or hexamethylene tetramine.  A layer of the vulcanizable rubber composition free from paraformaldehyde, hexamethylene tetramine, and solvent is then applied to the coated surface and the assembly vulcanized at 307 DEG  F. for 20 minutes.
