Title: Improvements in reaction operating lift producing devices for aircraft
IPC: B64C29/00
Filed: 1957-06-21
Abstract: 866,099. Aircraft. BERTIN ET CIE. June 21, 1957 [June 25, 1956 ; March 1, 1957], No. 19586/57. Class 4. [Also in Groups XXVI and XXVIII] An aircraft comprises a structure having a load carrying body and a gas generator, and an ejector comprising a wall external to or at the periphery of the structure and defining an air passage open at both ends and having its axis vertical when the aircraft is in its takeoff attitude, a jet forming nozzle external to or at the periphery of the structure, and facing downwardly when the aircraft is in the said attitude, and a duct leading from the gas generator to supply the nozzle with gas and thus induce a downward flow of air through the nozzle. Figs. 1 and 2 show a fuselage 1 with a pylon 2 supporting a longitudinally extending arm 3. Two gas turbines 8 and 9 with a common air intake 10 discharge into conduits 8a, 9a feeding manifolds 6a, 7a respectively through rotary joints. The manifolds discharge downwardly through annular nozzles 6, 7, entraining air through convergent-divergent ducts 4, 5 to provide lift. The two ducts, nozzles, and manifolds can be tilted together about the axes of the rotary joints to provide propulsive thrusts. The gas turbine exhausts are also connected to rearwardly pointing nozzles 16 controlled differentially for your control, and to nozzles 21 pointing downwardly and controlled differentially for roll control. By-pass nozzles 21a are controlled by valves to vary the exhaust flow to nozzles 6 and 7, Fig. 10, shows a form in which an annular manifold 135 is fed with gas under pressure through tubes 138.leading from the fuselage 133 and also supporting the manifold, and the gas is discharged through an annular nozzle 137, entraining air through the space between the fuselage and manifold. In Fig. 11, a convergent slot 101 is formed in a wing 122, and air is entrained through the slot by gas discharged from a nozzle 103 surrounding the slot. When the device is not in use, the lower wing surface is faired by a plate 123 movable by a jack 124. In Fig. 12 (not shown), air is similarly entrained through a slot formed between twin fuselages. Figs. 3-6 (not shown), disclose aircraft each deriving lift from four convergent divergent vertical ducts dispersed at the corners of a rectangle. Air is entrained through each duct by a downwardly discharging nozzle on the axis of the duct, fed from a gas turbine. The nozzles may be controlled differentially to control the aircraft. The aircraft of Figs. 5 and 6 comprises a platform and fore and aft loading ramps. In a similar embodiment, Figs. 8 and 9 (not shown), the ducts are universally mounted. In Fig. 7 (not shown), a duct is formed between an annular wing and an internal concentric fuselage, which comprises a rearwardly discharging gas turbine. The exhaust of this may be diverted to two annular nozzles within the duct. Fuel may be burnt in the exhaust or the entrained air within the duct. Ducts such as those of Fig. 1 may be made from. annular steel reinforcements and canvas or plastic walls.

Title: Production of pantothenaldehyde and acetals thereof
IPC: C07C233/00
Filed: 1951-08-20
Abstract: Pantothenaldehyde or acetals thereof are prepared by reacting a -hydroxy-b ,b -dimethyl-g -hydroxy butyryl amide with acrolein or acetals thereof.  The reaction may be carried out in the presence of solvents which are inert to the reactants, e.g. absolute ethanol or methanol and with heating and stirring.  The hydroxyamides employed may be prepared by reacting a  - hydroxy - b ,b  - dimethyl - butyrolactone with dry ammonia gas in a solvent, e.g. methanol; alternatively the solid lactone may be used in absence of solvent. In examples: (1) a -hydroxy-b ,b -dimethyl butyrolactone is reacted with dry NH3 whilst cooled with ice, the hydroxy amide formed is dissolved in absolute ethanol and reacted with acrolein at 35-40 DEG C. yielding pantothenaldehyde; (2) the acrolein in (1) is replaced by its dimethyl acetal resulting in the formation of pantothenaldehyde dimethyl acetal; the diethyl acetal may be formed similarly.

Title: Improvements in or relating to thermo-electric devices
IPC: G01K7/06
Filed: 1943-12-01
Abstract: 577,109. Thermo-couples. CLARK, C. H. W., SUGDEN, J. A., and STEATITE & PORCELAIN PRODUCTS, Ltd. Dec. 1, 1943, No. 20052. Drawings to Specification. [Class 53] A thermo-couple intended for use as a pyrometer has one of its elements formed of a ceramic body consisting of or including titanium dioxide so as to be electrically conducting. The other element may comprise a metal. In the form described in detail the ceramic element is in the form of a tube housing the other element. The end of the tube at which the " hot " junction occurs is closed and the junction is effected by electroplating the metal, nickel for example, of the other element on to the inside of the bottom of the tube, the metal element being completed by wire attached to the plating but insulated from the tube. The cold end of the tube may also be plated to afford good electrical contact for completing the circuit. Both ends of the tube may be closed and the tube filled with a reducing gas to prevent conversion of the titanium oxide to its yellow non-conducting form at high temperatures and to permit the use of the base metals, carbon or silicon carbide for the second element. Results are given ,for a thermo-couple having the ceramic element in the form of a rod consisting of 96À5 per cent. titanium dioxide and 3À5 per cent. clay and the metallic element of platinum, showing a sensitivity of about 0À6 millivolts per degree C over a range from-68 C. to 1360 C. Similar results are obtained with a ceramic element in the form of a tube having 97À6 per cent. titanium dioxide, 2À0 per cent. clay and 0À4 per cent. beryllium oxide. The ceramic element may be of strip or other form as well as of tubular or rod form. Methods of producing suitable ceramics are described in Specification 467,113, [Group V].

Title: Improvements relating to the copying of lenticular film
IPC: G03C7/14
Filed: 1937-07-20
Abstract: 493,804. Copying lenticular colour films. ORTHOCHROMA FILM-GES., and ADAM, M. July 20,1937, No. 20090. [Classes 98 (i) and 98 (ii)] Registration between the lenticles of the original and copy films, in printing by contact or projection, is secured by providing the films with edge markings corresponding to the lenticles and projecting these on an enlarged scale on a projection surface and using them for registration. The markings may be formed by planing off the upper surfaces of the lenticles in the margin and filling the depressions with coloured material. Preferably, different colours are used for the two films, e.g. blue and yellow, register being correct when the mixture colour (green) is seen without fringes. To avoid the formation of a moire pattern, the lenticles of the picture area of the original film may be removed chemically or mechanically, or filled with a filler having the same refractive index as the material of the film. To avoid variation of the angle between the lenticulation of the film and its edges, the films may be cut to the correct width simultaneously with the embossing of the lenticles, dished cutters mounted obliquely being preferably used. Fig. 4 shows an apparatus for projection printing. The films are passed through gates 11, 12, one at least of which is adjustable laterally, and one of which is capable of rotation in its own plane. Copying is effected by the objective 14 which is adjustable axially and laterally. To obtain correct transverse movement of the objective, when this is moved axially, to compensate for shift of the edge of the image, the lens carriage 22 carries a roller 25 bearing on a bar 26 carried by a block 29 and adjustable as to inclination by a micrometer screw 27. To compensate for wandering of the lenticulations across the film, optical flats 33, 33<1> controlled by snail cams are provided. The register marks on the film edges are projected by lens systems 15, 15<1> onto a screen 16. Fig. 9 shows the arrangement for contact printing. The films 11, 12 are fed past a narrow slit 13 having enlarged ends so that images of the margins may be projected by objectives 15 onto the screen 16. One gate 19 is rotatable in its own plane to secure parallelism of the lenticles. The relative positions of the films can be adjusted by rollers 43, 43<1> bearing on them.

Abstract: 583,327. Actuating controllers and brakes. RANSOMES, SIMS, & JEFFERIES, Ltd., and RANSOME, D. P. Oct. 18, 1944, No. 20115. [Class 38 (iii)] In vehicle; crane, or like control gear wherein a setting lever 1 can be moved to unfasten the locking bolt 15 and to displace the crank 7 from a neutral position, so that operation of a pedal or the like, acting through rod 12, will move the crank 7 and the controller drum spindle 19 in a direction (" forward or " reverse ") determined by whether the lever 1 is in position I or II (Fig. 2), the angular motion of the locking bolt 15 turns the cam 22 to move the brake lever 21; thus the movement of the setting lever 1 to either side of the neutral position will take off the vehicle brake. The cam 22, which is fixed on shaft 11, engages pin 23 on the lever 21; the latter turns freely on spindle 19 and actuates the brake through rod 24. The bolt 15 is slidably mounted on a member 16 secured to shaft 11. The lever 1 slides through sleeve 2 pivoted at 3 and is pivotally connected at 5 to lever 6 which carries the bolt 15 and has a slot 9 engaging the crank pin 8. A spring 18 can move the bolt 15 downwards, the lower end of the bolt entering a central hole or gap in a lock plate comprising two mutually inclined plates 17. Specification 558,139 is referred to.
