Abstract: 1,100,957. Controlling missiles. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. 4 March, 1965 [5 March, 1964], No. 9284/65. Heading B7G. A crossed wing missile is controlled by a localizer beam and carries computing equipment for measuring the distance from the beam in y and z directions, and damped accelerometers responsive to acceleration in y and z directions, signals from the computing equipment and the accelerometer being supplied to a stabilizer controlling aerodynamic control surfaces. The accelerometer is heavily damped (e.g. the damping coefficient is 15 instead of the usual 0À7), so that at the range of natural frequencies of oscillation of the missile about the localizer beam, damping is proportional to the velocity at which the missile approaches the beam, and below this range, damping is proportional to the acceleration. The accelerometer (Fig. 5, not shown) comprises a mass coupled to a variable resistor in a bridge circuit, and restrained by an electromagnet. Current from the bridges passes through the electromagnet and through a resistor and capacitor in parallel, to produce currents proportional to displacement and velocity of the mass.

Title: Improvements in and relating to gas-blast electric switches
IPC: B62D43/00
Filed: 1935-03-26
Abstract: 433,933. Fluid - blast switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. March 26, 1935, No. 9433. Convention date, March 26, 1934. [Class 38 (v)] In a gas-blast switch in which the opening operation produces the arc-extinguishing blast by means of a piston or the like under the action of an energy - accumulator, means are provided for charging the latter for the production of the compressed gas independently of the actual switching-in movement and during the switching-in operation, whereby both operations can be performed by hand. To close the switch, the arm e is moved to the dotted position in which it is held by latch k, so raising the piston b and tensioning the spring f. The arm g is then moved to the dotted position in which the movable contact a engages and seals the fixed nozzle contact c, in which position it is held by the engagement of rod h with latch m. To open, the latch k is moved by hand or by an electromagnet, so enabling the spring f to pull down the arm e and compress the air in cylinder d. Near the end of its travel, the arm e strikes the latch m and frees the rod h, the spring i lowering the contact a and releasing the compressed air from the cylinder. The arrangement ensures that the energy accumulator is charged before the switch can be closed.

Abstract: 1,084,731. Wet grinding ball mills; agitators. A. SZEGVARI. March 10, 1964 [March 11, 1963; Oct. 2, 1963], Nos. 9599/63 and 38840/ 63. Headings B1C and B2A. An agitator 2, Fig. 2, in an attrition mill for grinding and dispersing materials suspended in liquid in a vessel 3 containing a plurality of attrition elements e.g. balls 1, comprises a central shaft 6 and activators 10 carried on supports 9 projecting from .the shaft. The activators are arranged to set up intense agitation of the media in the presence of the material to be treated while rotating with the agitator and while other portions of the rotating supports moving at different radial distances from the shaft maintain relative quiescence of the media. In operation, scoops at the bottom of the agitator 2 lift the balls 1 from the bottom of the vessel, and the balls are retained by a screen 4. In a further embodiment, the activator supports 21, Fig. 7, are all of the same length and extend at right angles to the shaft in which they are positioned in holes 22 so that one end of each to which an activator 23 is attached projects from the shaft only half as far as the other end. The activators are distributed in the vessel to effect uniform agitation. In a larger vessel activators 31, 33, Fig. 10, may be provided on each support 29 to effect agitation in three cylindricale zones 1. .3. In all the embodiments the leading edge of each support tapers to a knife edge to promote minimum rotation of the attrition elements as a mass. In a further embodiment, flat plates 40, Fig. 14 provide supports for activators 42, 43 which are spaced around a shaft 41 so that no two activators move in the same annular path about the shaft. Where activators are located at different distances from the shaft, those activators which are at the smaller radial distance from the rotational axis may be larger than those at the greater radial distance.

Abstract: 211,743. Schember, K., and Joksch, R. April 11, 1923. Printed records, apparatus for giving.-A device for preventing a printed record being obtained unless the scale beam is in equilibrium comprises a pivoted feeling or locking member moved towards the beam by the rotation of a cam disc or equivalent, the mechanism being arranged so that if the locking member fails to enter a notch in the beam, the force expended on the locking device does not act on the beam but is completely absorbed by the pivot pin of the locking lever. As shown, the printing mechanism is operated by rotating a crank 9. The shaft 1 of the crank carries a cam 2 which raises a lever 14 against the opposition of a spring 15. If the scale beam 7 is in equilibrium a threearmed feeling or locking lever 4, 12, 13 enters a notch 10 on the scale beam and follows the lever 14 as far as is permitted by a pin 16. The rotation of the crank 9 may then be continued to perform the printing operation. If, however, the beam is not in equilibrium the arm 4 fails to enter the notch 10 and the arm 12 obstructs a projection 2<11> on the cam and prevents a printing operation being performed. The pressure due to the obstruction of the projection 2<11> is taken up by the pivot 14' without acting on the scale beam. After the operation of the printing apparatus has commenced, the type bar is locked to prevent a change in the resulting record, by means of a cam-operated pawl on the shaft 1.
