Abstract: 301,199. Rope, F. M. Nov. 22, 1927. Steering and balancing.-For moving the elevator, rudder or ailerons of an aircraft or the control surfaces of a watercraft a lever is fulcrummed about an axis fixed to the control surface at an acute angle to the hinge axis and its free end is constrained to move in a plane to which the fulcrum axis is not normal. An aircraft rudder is shown having an inclined spindle 7 fixed thereto to form the fulcrum of a lever 4 provided with a guide wheel 5 moving between vertical guides within the fuselage. The end of the lever 4 is moved vertically to effect movements of the rudder by cables, or by rack and pinion or screw and nut gear actuated by the rudder bar or a servo motor. More than one lever may be used in order to distribute the torque along the hinge axis, and these levers may be moved together in the same direction or they may be moved towards or away from one another. The guides 6 may be replaced by a radius rod or by a second lever pivoted about a transverse axis passing through the hinge axis 2 of the rudder. Where unequal displacements on the two sides of the mid position are required as in aircraft ailerons the spindle 7 is set in a plane making an acute angle with the median plane of the control surface instead of in a plane normal thereto.

Title: Improvements relating to aircraft propulsion systems and power units
IPC: F02C3/08
Filed: 1939-12-09
Abstract: 577,971. Gas turbines. WHITTLE, F. Dec. 9, 1939, No. 31883. [Classes 110 (i) and 110 (iii)] A centrifugal compressor with intake eyes on both sides of the plane of rotation discharges tangentially through a series of outlets to a corresponding plurality of combustion chambers in which the general direction of flow is axial. The combustion products pass to an annular nozzle chamber and so through a nozzle ring to a turbine which exhausts axially. The compressor outlets, the combustion chambers and the ducts to the nozzle chamber are arranged symmetrically about the common axis of the compressor and turbine. The unit may be used for generating shaft power or for jet propulsion of aircraft. The impeller 1 has radial vanes 1A on each side of the annular web 1B and is arranged in a casing having intake eyes 2A, 2B, a radially convergent part 2C, and a parallel walled diffuser part 2D fitted with fixed vanes 2E and provided with a series of tangential outlets. Air trunks 3, bolted to the outlets have bell mouths 3A entering combustion chambers consisting of cylindrical air casings 5 surrounding flame tubes 7A in which the fuel burners 11 are located. Adjacent air casings are interconnected by trunks 5A surrounding trunks 7F connecting neighbouring flame tubes. Each group of burners is connected to a supply chamber 23 and these chambers and the pilot burners 6A are respectively connected to ring main supplies by pipes 23A, 6B. The combustion chambers and burners are described in Specification 577,972, [Group XI]. Elbows 7D and ducts 7E carry the combustion products to a nozzle ring 8 feeding a single stage axial flow turbine 12. The ducts 7E are double walled, the interwall space carrying cool air from the chambers to the turbine. The turbine exhaust flows through an annular chamber, formed by a frustro-conical wall 10A and a stream-lined fairing 11 supported by three stream-lined hollow struts 11A, to the propulsion jet. The turbine wheel has an integral shaft 12B splined into a quill shaft 13 secured to the rear side of the impeller. A stub shaft 14 secured to the forward side of the impeller drives fuel and oil pumps through pinion and worm gearing. The shafts are carried by a bearing 15 and a rear bearing in an extension 16 of the compressor casing. The rear bearing may be air cooled as well as lubricated, the air serving to blow the oil on to the bearing. A scavenge pipe 18 collects the oil. Oil to both bearings may be fed through nozzles associated with an air stream. Water jackets 11D, 17 are arranged on either side of the turbine wheel. Specification 347,206, [Group XXXI], also is referred to.

Title: Direct current electroluminescent phosphor crystals, and direct current electroluminescent panels
IPC: H05B33/14
Filed: 1961-09-06
Abstract: A method of preparing D.C. electroluminescent phosphor crystals comprises applying stress to photofluorescent, substantially non-D.C. electroluminescent, triboluminescent phosphor crystals, the stress being insufficient to break the crystals but sufficient to extinguish the photofluorescent and triboluminescent properties of the crystals and to make them D.C. electroluminescent.  The crystals can be embedded in a viscous film before being stressed and the film can be of a resin which is cured after the crystals have been stressed.  The viscous film can contain an epoxy resin, a phenolic resin intermediate, and polyvinyl methyl ether in a weight ratio of about 56 : 32 : 12. The crystals can be sprayed into the film, the later-arriving crystals striking the embedded crystals and stressing them. Alternatively, the embedded crystals can be stressed by spraying them with hard particles which are of a material different from the crystals and which do not react with them, e.g. other phosphors, silicon dioxide, clays, nitrides, carbides and metal particles.  In a further example the phosphor crystals, embedded in a resin film, are stressed by an electrical discharge apparatus, such as a Tesla coil.  Other methods referred to are the use of ultrasonic waves, overlaying the film containing the crystals with a polymer film and passing a roller over its surface, placing a glass plate over the embedded crystals and applying an angular force, and incorporating the crystals in a vehicle to form a printing medium, the crystals being stressed while the medium is being printed on a substrate. Phosphors referred to are ZnS(Mn), ZnS(Mn, Cl), ZnS(Cu, Mn), ZnS(Pb, Mn), ZnCdS(Mn), ZnCdS(Cu, Mn) and ZnCdS(Pb, Mn).  Some of these phosphors also contain KCl, ZnO and a trace of Si.
