Abstract: 1,030,238. Helicopter rotors. LOCKHEED AIRCRAFT CORPORATION. Sept. 18, 1963 [Dec. 31, 1962], No. 36716/63. Headings B7G and B7W. A helicopter rotor system comprises a rotor driveshaft 26 (Fig. 1, not shown), a plurality of non-articulated rotor blades 12, 14, 16 attached to the drive shaft, a rotor control gyro having a plurality of weighted cross arms 28, 30, 32 and supported above the blades for universal tilting movement and for vertical movement, linkages 82 connecting the control gyro and the blades for changing blade pitch on relative displacement of the gyro and rotor planes, a constant velocity joint (Fig. 2, not shown) through which the gyro is driven, a swash plate (Figs. 3 and 4, not shown) below the drive shaft, and control rods 72 connecting the swashplate and the gyro and contained within the drive shaft. The swashplate is connected to the cyclic stick through hydraulic boosters and spring connections whereby movement of the stick is translated to a force on the swashplate which is transmitted to the gyro through the rods 72 causing it to precess. This produces cyclic pitch changes of the rotor blades, through the linkages 82. Each cross-arm 28, 30, 32 leads by between 30 to 60 degrees the rotor blade to which it is connected, and has at its end a mass 160 which also forms an aerodynamic lifting surface which provides speed stability by causing the helicopter to pitch nose up on increasing speed.

In teleprinter apparatus, a transmitter effecting transmission by the normal international teleprinter code is arranged to transmit a third shift signal and to transmit in this third case - shift group only those signal combinations having one definite ratio or a limited number of definite ratios between the mark and space elements of the combinations. The third shift signal may be constituted by, for example, the figure - shift signal followed by the letter G, which has no assigned upper case character, or preferably by the allblank signal, and is effective to move a typewheel to a position in which printing is effected from a third row of type. The figures 0 ... 9 may be sent as combinations in the third case group with 2 marks and 3 spaces, and the arrest of the type-wheel in a position corresponding to any other code combination results in an error sign being printed, preferably in red. When an error sign is printed, an alarm circuit may also be actuated. Additionally, signs, such as +, -, may be sent in the third case group as signal combinations with 4 marks and 1 space, all combinations other than those for the signs and numerals resulting in the printing of the error sign and the opertion of the alarm. In the column 3b, numerals are represented by combinations with 3 marks and the special signs have 1 mark and 4 spacing elements.

Abstract: 343,220. R÷ngten-ray apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. Dec. 5, 1929, No. 37369. Convention date, Dec. 5, 1928. [Class 98'(i).] Instantaneous, R÷ntgen-ray exposures are started by opening a shutter in front of the source of rays and are stopped by closing the shutter or by cutting off the discharge current from the R÷ntgen - ray tube. In a tube with an anode 1 rotated by the magnetic field of coils 3, the window 7 in the metal part 8 is closed by a cylindrical shutter 9 rotated around the tube bv the field of the coils 3, preferably at a speed slower than that of the anode 1. The shutter has two relatively adjustable parts 9, 10, Fig. 2, to adjust the size of the opening 17 and so the duration of the exposure. Movement of the shutter opens or closes contacts 14, 15 in a relay circuit controlling the circuit of the transformer supplying the tube. This supply circuit is closed when the shutter is in the position shown in Fig. 2, and, as the shutter rotates in the direction of the arrow, steady circuit conditions are established before the shutter opens, the exposure being stopped by the shutter and the supply circuit being then opened when the shutter returns to the position of Fig. 2 after one complete rotation. The Specification as open to inspection under Sect. 91 (3) (a) comprises also tubes with the circuit closing devices for actuating the shutter and the tube coupled together, and with the shutter closed whilst the preliminary load is applied to heat the cathode prior to the application to the full voltage. This subject-matter does not appear in the Specification as accepted.

Groove 24 also contains a resilient member 32 which is made of an elastomeric material e.g. synthetic rubber, and has a plurality of lands 36 whereby fluid in chamber H has access to member 26 to press it against faces 19 and a surface 30 in groove 24. Lubrication of bearings 18 is effected by leakage of fluid around journals 16 for the gears into an arcuate groove 38 situated in cover 20 in register with chamber L whereby the leakage fluid can escape to the lowpressure side of the pump. A further groove 22 in cover 20 contains an outer sealing member for said chambers. Alternatively, grooves 22, 24 may be formed wholly, or partly, in an end face of housing 10 and end faces 19 of bearings 18, respectively.
Patent GB-825691-A (GB)
Title: Improvements in the preparation of salts of epoxy-fatty acids
Filed: 1957-12-02
Abstract: Divalent metal salts of epoxidized fatty acids are prepared by initially reacting an epoxidized glyceride or oil with an aqueous solution of an alkali metal hydroxide to form the alkali metal salt of an epoxidized fatty acid, and subsequently reacting the alkali metal salt in the solution in which it is formed with a water -soluble salt of a divalent metal.  The saponification may be effected in the presence of a water-soluble organic solvent, e.g. methanol, ethanol, isopropanol, ethylene glycol or glycerol. Suitable starting material oils include epoxidized cottonseed, corn, olive, soybean, safflower and menhaden oils.  Sodium and potassium hydroxides are the preferred saponification agents. Suitable divalent metal salts include cadmium acetate, barium acetate, calcium acetate, magnesium acetate, zinc acetate, lead acetate, cadmium sulphate, cadmium nitrate and barium nitrate. The alkali metal hydroxide may be used in 10-20% stoichiometric excess, when it is desirable to neutralize the excess, e.g. with a C1-5 aliphatic monocarboxylic acid, such as acetic acid, e.g. to pH about 9, before adding the divalent metal salt.  The saponification may be effected in the presence of hydrogen peroxide, e.g. 0.1 to 3% by weight based on the epoxidized oil. Water may be added to the saponification mixture or to the neutralized saponification mixture, and the solvent may then be removed under reduced pressure.  Saponification temperatures mentioned are from 25 DEG  to 75 DEG  C.  Examples describe the preparation of the cadmium, calcium, magnesium, zinc and basic lead salts of the epoxy acids of soybean oil from epoxidized soybean oil.

Abstract: 326,572. Standard Telephones & Cables, Ltd., and Scaife, F. N. Dec. 20, 1928. Condensers of the differential type, suitable for measuring the capacity unbalance between or within the quods of a cable, are so arranged that measurements of more than one order of magnitude may be made, such as measurement of large capacity differences with moderate accuracy, and of small differences with higher accuracy. In the exploded view diagrammatic shown in Fig. 1, the moving quadrantshaped-plates 1 co-operate with two sets 3, 4 of fixed plates, and in the position shown, as well as in the position in which they are displaced 180‹, the capacity of two parts constituting the differential condenser will be the same. Some of the plates are cut away to form sets of quadrant-shaped plates 3<1>, 4', so that when the plates 1 are rotated from the position shown, only a small change of capacity takes place, whereas when they are rotated from the diametrically-opposite neutral position, a larger change takes place. The scale in the latter arrangement is coarser, and readings are less accurate, than in the former arrangement. In a constructional form, Fig. 4, two sets of fixed triangular plates 3, 4 have located between them the two sets of triangular plates 3', 4<1>, which are only half the area of the plates 3, 4, these being all mounted on pillars 11 between end plates 8, 9 in a casing 12.
