Title: Rotor blade
IPC: B64C27/473
Filed: 1946-06-17
Abstract: 613,288. Rotor blades. ROTARY RESEARCH CORPORATION. June 17, 1946, No. 18166. Convention date, June 21, 1945. [Class 4] A rotor blade for rotating wing aircraft, including an elongated envelope having a leading edge and a trailing edge has means connected with the envelope for adjusting the relative lengths of the two edges. The blade shown in Fig. 1 has, as the result of shrinkage warping of the envelope 12, the locus line 17 of centres of pressure swept back from the torsional axis 18 (which is in line with attachment spar 13); by means of the above adjustment such a blade may be flexed to bring the line 17 into coincidence with line 18; according to one form of the invention a blade may be originally produced with a forward swept centre-ofpressure line 17 when at rest but which, as the result of drag-forces, become straightened in flight; the adjustment device according to the invention may also be used for obtaining such a forward-swept line which becomes straightened in flight. In Fig. 5 is shown a blade, with a tubular attachment spar 13 near the leading edge and to which the envelope 12 is secured, and having an adjustment device comprising a threaded rod 19 screwed into blade tip 14 and received at its inner end in a clamp 22 bolted on the spar 13; a nut 26 is screwed up on the threaded rod to provide the adjusting tension. In a modification an adjusting thrustrod is placed near the trailing edge of the blade.

Title: Improved method and apparatus for generating, relaying, rectifying, transforming and amplifying alternating or pulsating currents
IPC: H01J31/06
Filed: 1924-07-30
Abstract: 220,297. Fisk, E. T. Aug. 9, 1923, [Convention date]. Thermionic amplifiers, detectors, and generators.-In a valve for use as a rectifier, relay, amplifier, or oscillation-generator, the electronemitter is located in the field of a reflector which is polarized electrically or magnetically when arranged within the envelope, or magnetically when arranged outside the envelope so as to produce a beam of electrons passing to two or more electrodes. The beam is oscillated between the anodes by a grid or by a transverse electric or magnetic field. In the rectifier shown in Fig. 1 a filament 22 is mounted in the focus of a parabolic reflector 26 connected with the negative terminal of the heating battery 21. Two anodes 18, 19, connected through a battery 20 and an indicator or like circuit 27 with the filament, are mounted one on each side of an anode 17, which is connected with the battery 20 through a high resistance 35. An inductance 13, coupled with an inductance 12 in the aerial circuit, is connected with two deflector plates 14, 15. The beam is normally concentrated on the anode 17, but is deflected on to the anodes 18, 19 alternately by the varying charges on the plates 14, 15 so that rectified impulses are received in the circuit 27. In the relay or amplifier shown in Fig. 2 an oscillatory circuit 43, comprising a condenser 44 and an inductance 45, is connected between the anodes 18, 19, and the midpoint of the inductance 45 is connected with the battery 20. The circuit 43 is tuned to the frequency of the incoming signals. In a modification, two inductances in a tuned circuit are coupled with inductances connected between the anodes 18, 19 and the battery 20. In one arrangement for generating oscillations the inductance 13, Fig. 2, is omitted and the plates 41, 42 are connected with the ends of the inductance 45. In the generator shown in Fig. 6 the ends of the inductance 45 are connected with the anodes 18, 19 and with deflector plates 41, 42 on the opposite sides as shown, and the phase is corrected by inserting a condenser 70 in each of the connections to the plates 41, 42.

Title: Improvements relating to dyeing silk black
IPC: D06P1/34
Filed: 1923-04-03
Abstract: Silk, either alone or in mixed goods, such as with cotton, is dyed black by treatment in a bath of fustic and haematin extracts to which an iron salt, such as "black iron," is subsequently added, and the colour fixed by means of tannic acid and tartar emetic.  In an example, silk piece goods are first entered into a boiling bath of haematin and fustic, to which "black iron," "blue stone," and acetic acid are afterwards added, and then treated in a second bath of haematin and soap and finally in successive baths of tannic acid and tartar emetic.  They are cleansed in a boiling soap bath, washed and acidulated.  The dyeings produced by the process are stated to be fast to warm soapy water but not fast to boiling soapy water.

Abstract: 1,105,419. High voltage switches. VYZKUMNY USTAV ENERGETICKY. 28 April, 1966 [14 Dec., 1965], No. 18593/66. Heading H1N. [Also in Division H2] In a disconnecting switch arrangement for a high-voltage power transformer (not shown), the contacts 3, 4 of an isolating switch, in series with the primary winding of the transformer, are opened when an explosive charge 6<SP>1</SP> is fired by pulse generating means in circuit with a short Circuit path completed to earth by a shortcircuiting switch 15, 16, which may be operated by an explosive charge 14. The moving contact 3 of the isolating switch is operated by a piston 2 on which the gases evolved by the charge 6 act. The piston carries a buffer 9 which enters an aperture 10 to brake the opening movement of the moving contact. The pulse generator may comprise a current transformer 8 with its primary winding in the shortcircuit path and its secondary winding connected to the detonator of the explosive charge 6<SP>1</SP>. To cause the opening of the isolator to occur in the interval in which the supply is interrupted by the operation of a main auto-reclosing circuit breaker, the detonator of the charge 6<SP>1</SP> may be controlled by a relay which when energized by the transformer 8 opens contacts to permit a capacitor to be charged from the transformer. When the short-circuit current ceases, the relay releases and closes its contacts to permit the capacitor to discharge through the detonator, Fig. 3 (not shown).

Title: Hardenable compositions containing polysulfide polymers
IPC: C08L81/00
Filed: 1961-05-24
Abstract: A hardenable composition comprises a hardenable low molecular weight polysulphide polymer, 5-100% by weight based on the polysulphide, of factice, and a curing agent the active ingredient of which is lead dioxide.  The curing agent may also contain a small amount of a fatty acid, e.g. oleic or stearic acid and a softening agent, e.g. dibutyl phthalate or a chlorinated hydrocarbon known under the trade name "Arochlor."  Fillers or pigments, e.g. TiO2, powdered aluminium, chalk, silica or carbon black may also be incorporated.  In example (1) liquid and solid factice are mixed and lead dioxide, stearic acid and dibutyl phthalate are added.  60 parts of the mixture with 100 parts of polysulphide gives a paste, which hardens in 1 hour or less at 40-60 DEG C.  (2) is similar but contains TiO2 and/or Al powder. (3) uses liquid factice and calcium carbonate as filler, (4) uses solid factice without a filler. (5) is similar to (1) but omits the stearic acid and dibutyl phthalate.  The products are useful as sealing or caulking compositions.

Abstract: 380,861. Transferring blanks ; chucks. STENMAN, P. L., 32, Ostermalmsgatan, Stockholm. June 29, 1931, No. 18801. [Class 83 (iii).] In a lathe &c. chuck, particularly for holding screw blanks during threading, the blanks are fed singly through a feed tube to the chuck jaws by means of a reciprocating push rod which is magnetic so as to hold each blank in alignment with the jaws. The chuck jaws 1 are pivoted at 9 to the body and are oscillated to grip and release a blank 4 by means of rollers 13 and projections 14 on a sleeve 5 which is reciprocated by a yoke and lever 2 and cam 3. The push rod 6 retires sufficiently behind the feed tube 7 to allow a blank 4 to be inserted in front of it, whereupon the rod transfers the blank to the tube and passes through an electromagnetic coil 8 whereby it is magnetized and causes the blank to adhere to the flat end thereof in alignment with the jaws. The cam 3 opens the jaws to the full extent to allow a finished screw to drop out by gravity or be pushed out by the succeeding blank, then partially closes them to allow the shank, but not the head, of the next blank to pass through and finally closes them to grip the blank for machining. Instead of using the coil 8 and a soft iron push rod 6, the rod may consist of steel which is permanently magnetized.
