Title: Apparatus for performing work by means of magnetostriction
Inventor: HALSALL JAMES RICHARD
IPC: G05B11/01
Filed: 1953-03-14
Abstract: 728,326. Reciprocating motors. IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 12, 1954 [March 14, 1953], No. 7106/53. Class 35. A device for obtaining continuous motion from a body of magnetostrictive material comprises means for successively restraining and releasing the body in timed relation to the magnetostrictive motion. In the form shown in Fig. 3, a magnetostrictive rod 10, e.g. of nickel, is magnetized by a coil 13 and restrained by electromagnetic, e.g. magnetic fluid, clutches 11, 12 fed from the A.C. supply 20 through a phase-splitting device 21 so that they are fed with currents mutually displaced by 90 degrees. The direction of the motion of the rod 10 is determined by the phase of the current supplied to the coil 13 which is controlled from 45 degrees leading to 45 degrees lagging by a network 22 including a saturable reactor 28 controlled from terminals 31. Negative feed-back from the movement of the rod 10 is provided by a movable core 30 in a tapped inductive coil 29 in two limbs of the network. In a form, Fig. 4, employing the volumetric change of a magnetizable liquid, e.g. magnetic particles or a closed metal ring suspended in oil, the liquid is contained in a closed circuit 32 with arms 33, 34. The motion is transmitted to hydraulic bellows 36 through magnetically-controlled valve 37 and fluid is drawn from reservoir 39 through valve 38. Flexible diaphragms 40, 41, 42, 43 may be provided to separate the fluids in different parts of the system.

Title: Improvements in or relating to pressure-clearing opaque films
IPC: G03F1/90
Filed: 1963-02-21
Abstract: An opaque, pressure-clearable, porous polymer coating is formed on a support by: (a) forming on a non-fibrous support a coating of a solution of a water-insoluble liner polymer in a water-soluble dialkylamide having a boiling point of at least 100  DEG C., e.g. dialkylamide having C1-4 especially C1-2 alkyl groups, which contains a hydroxyl-containing liquid non-solvent for the polymer of boiling point not above 100  DEG C., e.g. water or a C1-4 alkanol, the amount of non-solvent being 45-97% of that required to form a hazy solution, (b) treating, e.g. by immersing, the coated support with a non-solvent for the polymer which dissolves and extracts the dialkylamtde, so coagulating the polymer and, (c) removing the non-solvent from the coating.  Specified linear polymers are those of vinyl halides, acrylic monomers, e.g. methacrylonitrile, acrylic esters, mixtures thereof and copolymers of such monomers with minor amounts of vinyl organic esters and other vinyl-type monomers, e.g. vinyl chloride/vinyl acetate/maleic acid copolymers.  Specified base materials are films of polyethylene terephthalate, cellulose esters, superpolymers, e.g. vinyl chloride-vinyl acetate copolymers, polyvinyl acetals, polystyrene, polyamides and polyesters, e.g. polycarbonates, polyethylene terephthalate/isophthalate, and esters formed by condensing terephthalic acid and dimethyl terephthalate with propylene glycol, diethylene or tetramethylene glycol and cyclohexane-1,4-dimethanol and the films described in Specification 718,422.  Specifications 741,294, 741,441 and 919,671 also are referred to.

Abstract: 664,610. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 21, 1949. [May 5, 1948] No. 7619/49. Class 38 (iii). [Also in Group XXXV] In a system wherein a D.C. motor 1 is supplied from A.C. mains 3 through rectifiers 7, 8, and the motor speed is regulated under the grid control of a master valve 38 the speed being predetermined by a variable grid resistor 34 and regulated under control of bias resistors 44, 19 responsive to variations of armature current and voltage respectively, ripple voltages in the grid circuit of the valve 38 and arising from fluctuating armature conditions, are reduced by a negative feed-back circuit for the valve comprising resistor 57 and condenser 58. The condenser 58 is short-circuited over contacts 13 of the "start" contactor 12 when the motor is at standstill. The feed-back circuit provides in addition to ripple reduction during running, proper starting conditions for the motor since the condenser 58 ensures gradual bias variation on the rectifiers 7, 8 and the consequent prevention of high peak currents to the motor armature circuit during starting. A modified system is described, Fig. 2 (not shown), wherein (1) the motor is supplied from 3-phase A.C. mains (2) the bias voltage derived from the armature current is supplied through a transformer and rectifier, a diode limiter also being included to prevent excessive armature current and (3) instead of providing a bias by resistor, a bias voltage dependent on speed of the motor is generated by a pilot generator driven by the motor.

Abstract: 288,426. Misch, O. March 21, 1927. Producers.-In a process for generating water gas from bituminous fuel, the lower end of the preliminary distillation retort 1 is heated externally by a compressed air-water gas burner 11 provided with baffles 12 for producing eddying or turbulence or by oil or coal dust burners or similar means, so as to effect an intensive local heating of the contents of the lower portion of the retort to more than 700‹ C, the temperature decreasing towards the charging hopper 3 to about 250' C. The upper end of the retort which comprises two shafts 1a, 1b, is supported on masonry 6 by means of elastic sheet iron plates 4, 5. During the " blow " air is supplied through a pipe 20, combustion gases escaping through a dust chamber x and combustion chamber 13 into heating flues 14 of the retort and thence through a waste heat boiler 16 and chimney 17. When steam is admitted through a valve 23, the air valve 21 and a register 25 between the chamber 13 and dust chamber x are closed, and the water gas produced rises through the retort, passing with illuminating gas through a pipe 26. The register 25 may be left open for a while after the air valve is closed and a small amount of steam admitted so that residual carbon dioxide and nitrogen are passed into the chimney. Part of the water gas produced is fed to the burner 11 through a pipe 9 together with compressed air through a pipe 10. Tar or tar oil may be injected into the retort if coke is not required through pipes 28 by means of steam supplied through a pipe 35. Specification 276,530 is referred to.

Filed: 1925-03-24
Abstract: 250,003. Bossong, J., and Maschinenfabrik M³nchen Kommanditges. March 24, 1925. Tobacco leaves in bundles e, Fig. 1, are loosened and separated one from another by causing them to pass between two rows of resiliently mounted rollers a, b and alternately on opposite sides of the members of a third row of rollers or other blunt members a situated between the rows a, b. The rollers &c. d or the rollers a, b are adapted to be moved laterally by cams on their spindles and, in returning under the action of springs, to impart glancing blows to the bundles e, whereby the individual leaves are loosened. The final separation of the leaves is effected by rotary fingering members f which rub the bundles against roughened wall g. When the leaves in the bundle are folded one within another, the initial separation is effected by passing the bundles between pairs of resiliently mounted rollers b, Fig. 5, driven by skew gearing b<1>, b<2> at successively greater speeds. One of the shafts i<1>, i<2> carrying the pinions b<2> may be rotated at a higher speed than the other, thus causing the leaves to be rolled off from the bundle.
