Title: Improvements in or relating to brake and landing flaps for aircraft
IPC: B64C13/00
Filed: 1942-07-25
Abstract: 576,093. Controlling aircraft. WESTLAND AIRCRAFT, Ltd., and DIGBY, F. J. W. W. July 25, 1942, No. 10424. [Class 4] An aircraft is fitted on each side with upper and lower braking and landing flaps, the flaps on each side being operated by strut, members meeting at a common pin point which is controlled by at least one of two independently operable jacks respectively for use during braking and landing. In one form, upper and lower flaps a, bare actuated by struts f, h meeting at a common pivot k which is connected to two independently operable jacks m, n connected to fixed points o, p on the aircraft. When the jack m is actuated, the flaps a, b are splayed apart through equal angles to act as air brakes, the jack n swinging freely about its pivot without change of length. When the jack n is actuated, both flaps are depressed to act as landing flaps, the lower flap moving through a greater angle than the upper flap, the jack m turning freely about its pivot o and remaining unchanged in length. The flaps are arranged outboard of the engine nacelles of a twin-engined aeroplane, the nacelles enclosing the actuating mechanism. An additional flap v, inboard of the engine nacelle, is depressed simultaneously with the depression of the flaps a, b by means of a link t connected to a bracket u on the upper surface of the flap v, and to a lever s on a shaft r extending from the nacelle where it is connected to a pair of levers q actuated by links i, on each side of the jack n, connected to the pivot k. The flap v controls the outlet for cooling air from a radiator arranged within a duct in the wing which is slightly open in the normal position and is opened further as the flap v is depressed. Fig. 9 shows a modification in which the two jacks m, n are connected to two levers 11, 4 pivoted at fixed points 12, 6. The lever 11 is connected to an upper braking flap a by a link 13. The lever 4 is connected by a link 7 to the junction of two links 9, 10 connected between the lower flap b and the junction of the link 13 with the lever 11. The lever 4 is connected by a torque tube 5 to a lever pivoted at 16 and having an arm 15 connected at 17 to a link for actuating the inboard flap v. In this case the flap a is not depressed as the jack n is actuated to depress the flaps b, v.

Title: Improvements in or relating to the production of metallic coatings on the surfaces of metals
Inventor: CLAYTON ERITH TAINTON
IPC: C23C24/04
Filed: 1951-03-22
Abstract: Metal articles are provided with a continuous coating of another metal by embedding them in a mass of clean malleable non-laminar particles of plating metal and impacting the particles so as to flatten and bond them on to the surfaces of the artcles in interfitting layers at a temperature below the melting point of the plating metal but high enough to permit the necessary distortion and flattening of the particles, the operation being carried out in a water-free gaseous or evacuated environment.  The plating of small articles such as nails, nuts, bolts and other small hardware, preferably after cleaning by pickling or abrasive tumbling, may be carried out by tumbling them together with the plating particles, and optionally additional impacting material such as steel shot, in a tumbling mill, in which the air is dried by the action of the plating particles, or to which a non-oxidizing gas (e.g. from solid CO2) is supplied, or which is evacuated.  The method is described as applicable to the coating of zinc, magnesium, aluminium, iron and steel articles with Al, Zn, Cd, Sn, Pb, Cu, Ag, Mg and Ni.  The temperature is preferably chosen so that while the metal particles do not melt on impact, they reach the minimum recrystallization temperature. Specification 740,075 is referred to.

Title: Improvements in or relating to roller bearings
Inventor: LAMM AKE MAGNUS
IPC: F16C25/06
Filed: 1962-03-19
Abstract: 990,553. Bearings. SKEFKO BALL BEARING CO. Ltd. March 19, 1962, No. 10475/62. Heading F2A. A method of determining an axial dimension of a part of a tapered roller bearing which has a guide-ring engaging the ends of the rollers having the greatest diameter and has a guidering urged into engagement with the rollers, so that the bearing when finally assembled has a desired pre-load or clearance, comprises applying a known load to the guide-ring and towards the rollers through members which can be displaced axially in relation to one another, one of which is integral with the inner race and the other of which acts directly or indirectly on the guide-ring, and measuring a dimension which changes on relative axial movement of said members and is equal to, or is related in known manner to, the required dimension. In an embodiment the bearing has an inner race 11, Fig. 1, mounted on a shaft 14, an outer race 10 mounted in a recess 16 of a casing 15, and rollers 12 abutted by the guide-ring 13 which is engaged by a spacer-ring 17. The guidering 13 and the spacer-ring 17 are mounted on a spacer 26 and loading is effected by tightening a nut 28 on the shaft 14 which urges a coupling-member 27 towards the rollers. The thickness of the spacer-ring 17 determines the desired pre-load or clearance in the bearing. In order to determine the required thickness of the spacer-ring 17, the latter is removed along with the member 27 and the nut 28, and a device comprising telescopic members 40, 41, Fig. 2, is positioned on the shaft 14, the member 40 being attached to the shaft by a nut 42 so as to bear against the sleeve 26 and retain the parts in their assembled positions. The required load is applied by supplying pressurized fluid through a pipe 43 to a sealed space 44 between the members 40, 41 so as to force the latter against the guide-ring 13. The distance between faces 40b and 41b of the members 40, 41 is the required thickness of the spacer-ring 17 and may be determined by measuring a related distance " Y " between faces 41a and 40a of the members 41, 40. In modifications, the load is applied by springs of known ratings; and the pre-loading or clearance is effected by a spacer located between the guide-ring and the inner race, the required thickness of the spacer having been pre-determined by replacing the latter in the assembly with a plastically-deformable ring and applying the load thereto, the final thickness thereof being relative to the required thickness of the spacer. Specifications 990,551 and 990,552 are referred to.

Title: Improvements in and relating to mechanism for lifting floating bodies
IPC: B66D1/48
Filed: 1934-04-10
Abstract: 432,861. Winches. POLLAK, J. E., 20, Holborn, London.-(Kampnagel Akt.- Ges. vorm. Nagel & Kaemp; 4, Barmbeckerstrasse, Hamburg, Germany) April 10, 1934, No. 10722/35. Divided out of 433,392, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 23, 1935. [Class 78 (v)] [See also Group XXXIII] In winches for lifting and lowering floating bodies which are rising and falling owing to wave motion, means is provided for giving the lifting hook a similar up-and-down movement to that of the body before attachment of the hook thereto, thus preventing collisions between the heavy hook and the body, which may be a fragile structure, such as a sea-plane. The hook 12 is carried by a rope 11 wound round a drum 10 freely mounted on a shaft 19 and on an extension 16 of the casing of a main motor 13. The motor pinion 26 drives the drum 10 through a gear-wheel 25 meshing with a toothed ring 27 fixed inside the drum 10, the wheel 25 being carried on a frame 18 fixed to the shaft 19. A secondary drum 50 is fixed to the shaft 19 which is driven through pinions 21, 22 by a secondary motor 14. A cable 51 wound on the drum 50 passes freely through a guide 52 on the hook 12. Fixed to the drum 50 is a ratchet wheel 30 adapted to be locked from rotation in one direction by pawls which are automatically electrically retracted when the current to the motor 13 is switched off. In operation the cable 51 is attached to the floating body and the effect of the motor 14, which may be electric or weight-operated, is to maintain the cable 51 taut. The shaft 19 thus oscillates in time with the wave motion, and imparts its swing to the drum 10, the motor pinion 26 being held against rotation, when the motor 13 is not energized, by an automatic brake 28. The hook 12 thus rises and falls with the waves, and its position relative to the floating body can be adjusted by operation of the motor 13, thus facilitating attachment. On energizing the motor 13 the ratchet 30 is gripped and therefore the shaft 19 held stationary, thus allowing the rope 11 to lift the load. The motor 14 may be replaced by a weight attached to a rope, or may be arranged inside the drum 10. The differential effect on the hook 12 may be obtained by two separate drums, one driven by the motor 13 and the other by the motor 14, the drums carrying the ends of a single rope reaved over a pulley on the hook. Specification 433,392 is referred to.

Abstract: 493,876. Intercommunication systems. GRAHAM & CO., Ltd., A., and VAUGHAN, C. H. April 17, 1937, No. 10976. [Class 40 (iv)] In an intercommunication system in which calls are guarded against intrusion by unwanted parties and in which conference calls may be set up, each station includes a key and a relay controlled thereby appropriate to each other station for setting up calls thereto, the relay being prevented from operating if the corresponding station is engaged. The Figure shows two stations A, B of a 5-station system having a home wire and a guard wire for each station, these being connected to terminals L, S at that station and to terminals corresponding to that station at the other stations. The subscriber at A wishing to call station B lifts the combined instrument HM, operating springs CS, and throws key AKB, which connects battery over terminal S to the guard wire. Relay AAS energizes and completes the local circuit of the instrument HM in series with an impedance Z, the junction point being connected through condenser K to terminal L. Relay ARB energizes provided station B is idle, connects terminal L by way of terminal LB to the home wire of station B and applies battery by way of terminal SB to the guard wire of that station to operate the buzzer BZ and relay BAS thereat. Lifting of the instrument at B completes the local circuit which is connected through condenser K to the home wire. The connection is broken when key ARB is restored, and if the instrument is replaced without restoration of the key, the buzzer at A will operate. A third party may be brought into the connection by operation of the appropriate key at either A or B, and may be subsequently excluded by restoration of the key. If on the other hand station B is engaged, its guard wire is connected to battery either locally or at another station, and relay ARB which is connected thereto by key AKB is short-circuited and cannot operate. Relay AG therefore energizes, opens the local instrument circuit to prevent possible overhearing and lights lamp EL. The subscriber may leave the circuits in the calling condition, and the subsequent extinction of the lamp indicates when the wanted station becomes idle.
