Title: Improvements in or relating to screw propellers
IPC: B64C11/34
Filed: 1930-05-08
Abstract: 353,560. Screw propellers. AUTO. MATIC PROPELLER CO., Ltd., Vickers House, Broadway, Westminster.-(Assignees of Lougheed, V. ; 2121, New York Avenue, Washington, U.S.A.) May 8, 1930, No. 14184. Convention date, July 1, 1929. [Class 114.] Screw propeller blades are mounted in sockets on the boss and retained against centrifugal thrust by a group of flexible tie elements comprising a length or lengths of wire wound back and forward between each blade and the hub. The blade 1 has on its root portion a disc 2 and this is connected to a disc 3 on the hub socket by means of a wire 4 which is preferably slightly inclined to the axial direction. The wires are maintained in tension when the propeller is at rest by a cushion or spring pad 5. The tie elements are maintained at slight angles to the blade axes by a spring 7 normally tending to keep the blade arm 11 against a stop 8. When the propeller is revolving centrifugal forces acting on the blade produce a restoring couple to draw the flange 2 outwardly, to bring the wires 4 into parallel position and thus to rotate the blade into a new angular attitude. The maximum angle is limited by means of a stop 12. Upon a predetermined rate of revolution of the propeller the tie elements may be arranged so as to decrease the pitch angle. In a constructional form the boss is made in two parts bolted together and held by clamping rings 18. Situated fixedly therein is a ring 21 having a flange 3 which has its edge notched. The split ferrule 20 of the blade root has a notched edge 2 and the wires 4 are wound over the notches in both these members 2, 3. To maintain the tension, the blade root rests on a spring plate 5 and for controlling the pitch variation there is a plate 28 on the blade root and a plate 29 on the boss which are provided with intermeshing radial plates 32, 33, respectively, between pairs of which are rubber blocks 7. Movement of plate 32 relative to a fixed plate 33 is limited by the length of the slot 12 in a ring 8 fitted over the edges of the plates and fixed by its close fit with the plates 33.

Abstract: 606,508. Automatic - control systems. QUARTZ & SILICE. June 6, 1945, Nos. 14267 and 14268. Convention dates, June 7, 1944, and March 24, 1945. [Class 38 (iv)] [Also in Groups XXXVIII and XL (b)] Temperature.-In an optical pyrometer of the type in which the brilliance of a furnace is compared with that of a lamp filament, a photocell is arranged to give an A.C. output proportional to the difference between the brilliance of the lamp and that of the furnace. The Figure shows an arrangement in which light from furnace window S passes through lens O, shading wedge B, apertures D and D<SP>1</SP>, and falls on photocells C and C<SP>1</SP>. Filaments F and F<SP>1</SP> are connected in series to a common heating source and are of slightly difference thicknesses so that one is brighter than the other. These filaments are vibrated in and out of the views of cells C and C<SP>1</SP> so that unless their respective brilliances are the same as that of the background illumination provided by the furnace, cells C and C<SP>1</SP> will give A.C. outputs which are amplified and rectified by devices A and A<SP>1</SP> and the resultant D.C. voltages applied in opposition to instrument G. Since F and F<SP>1</SP> are of different brilliances, the D.C. voltages will not each reduce to zero at the same background illumination, but there will be an intermediate background illumination at which they cancel, meter G deflecting one way or the other according as the background brilliance and hence the temperature deviates from this intermediate value. Meter G may operate a circuit breaker to maintain the furnace temperature constant or operate a motor which moves wedge B, and also a temperature indicating pointer so that the abovementioned intermediate background illumination is restored, as in Fig. 3 (not shown).

The refractory material may be glass, e.g. petalite or a borosilicate or lithium aluminosilicate glass, porcelain, lithium alumino-silicate, alumina, zirconia, tungsten carbide or silicon carbide, a metal such as nickel or stainless steel or silicon. In the example, Fig. 1, green sheets of silicon are formed into a heat exchanger, Fig. 2 (not shown), for a Sterling engine the silicon being converted into silicon nitride during heat treatment. A layer formed from a slurry of silicon powder, polyvinyl butyral, dibutyl phthalate and methyl ethyl ketone was deposited on a carrier, dried, removed from the carrier, edge trimmed and sixteen of the layers were rolled down to give a composite sheet <SP>1</SP>/ 16  inch thick. Apertures were then punched to form sheets 1-4 which are painted with ethanol and stacked under a weight whilst the ethanol evaporated. The assembly, including a refractory tube 5, was then heated to 200‹ C. in air and held at this temperature for ten hours, followed by heating to 400-500‹ C. in air. Heat treatment in a nitriding furnace followed; the Specification includes a temperature-time schedule for the heat treatment. Instead of ethanol, toluene may be used.

Title: Improvements in and relating to fluid actuated compressors
IPC: F04B27/02
Filed: 1927-05-31
Abstract: 272,884. Pescara, R. P. June 17, 1926, [Convention date]. Actuating pumps by fluid-pressure motors.-A compressor comprises a motor cylinder 16, utilizing fluid under pressure, between coaxial compressor cylinders, the motor and compressor pistons being integral; the pistons are connected by synchronizing links and levers 27, 21, which control the admission and exhaust of the motive fluid. This fluid may be steam, or air from the compressors heated for example by combustion of fuel admitted by the air inlet means. Steam &c. is admitted through chambers at opposite sides of the motor cylinder, each chamber having a rotary distributing plate 31 having inlet slots 32 adapted to register with slots 35, in a stationary plate, opening into the cylinder. The plate 31 is pivoted on a stub shaft carried by the stationary plate. The lever 21 is pivoted by a sleeve 45 on the collar 44 of the plate 31, which turns on the stub shaft, the sleeve being formed with a notch engaging an abutment 43 on the plate to oscillate the plate. The fluid exhausts through a passage 49 controlled by a valve 51 carried by a spring-pressed piston 53. The cylinder space at the back of piston 53 communicates through pipes 57 with openings 58 in the fixed plate, and through pipes 62 with the extremities of the motor cylinder. The openings 58 are caused to register with openings 66 in the oscillating plate 31 a little before the openings 32, 35 come into register. At the end of the outstroke, the pipes 62 are opened to the interior of the motor cylinder. while the supply of fluid to the cylinder is cut off. The valve 51 is opened by its spring and the fluid escapes. As the pistons return under the action of residual compressed air, the levers 21 rotate freely at first and afterwards engage and rotate the, plates 31. The slots 66 are first brought to register with the openings 58 to admit the fluid behind the valve piston 53 and close the valve, since the motor pistons then cover the outlets of the pipes 62. The slots 66 admit fluid up to the end of the stroke. The fluid remaining in the motor cylinder is thus compressed, and when the ports 32, 35 register it has attained the pressure of the fluid supply. On the outstroke, the. inlet ports are closed near the beginning and the outlet valve opened towards the end of the stroke. Specifications 268,773, 268,782, 272,212, 290,416, 293,133, 293,477, and 294,967 are referred to.
