Title: System of control for a polyphase alternating current synchronous motor
IPC: H02P25/02
Filed: 1972-04-19
Abstract: 1379156 Automatic control of speed OTIS ELEVATOR CO 19 April 1972 [10 May 1971] 18195/72 Heading G3R [Also in Division H2] A polyphase A.C. synchronous motor has a rotor position sensing device including a pair of Hall elements, e.g. Al, A2, for controlling the supply of current to each of the stator windings A, B, C of the motor. One of each pair of Hall elements controls the supply of the 'in phase' component of the current in the respective phase winding and the other controls the supply of the quadrature component. Hall elements A1, B1, Cl are fed from a summing amplifier DAS and elements A2, B2, C2 from a multiplier QAM, both these devices receiving as inputs a desired torque signal TD and a signal +V T  representing the actual speed of the motor. In the embodiment shown, the rotor 14 of a motor for a lift 10 is mechanically coupled to the 2-pole permanent magnet rotor 16 of the rotor position sensing device which has a cylindrical stator yoke (not shown), the Hall elements being mounted on the inner surface of the yoke. Rotor 16 performs one revolution for every electrical cycle of motor rotor 14. A tachogenerator 15 feeds actual speed signals to devices DAS, QAM and also to an adder 28 which receives a command signal from speed dictation apparatus 30 which may also provide an output when the lift 10 is stationary. The output signals of elements A1, A2 are fed to circuitry 22, 23, 18 which vectorially adds them and feeds their sum via signal translating apparatus, comprising a sawtooth wave generator SWG, a pulse generator APG and an inverter circuit AI, to stator winding A. Windings B and C are similarly energized from elements B1, B2 and C1, C2.

[Also in Group XVI] A magnetic recording and reproducing machine employing an endless tape is characterized in that the tape control means comprise a magazine 1, in which the tape lays in random loops and which has two apertures each associated with a capstan and pinch roller assembly 2 and 3. A base-plate 6 mounted for rotation about its central axis has a central boss 7 and an eccentric roller 8. In the condition shown in Fig. 1, the tape is stored in the magazine and is driven by the capstan 3 which draws the tape from the opposite end of the magazine over the head 5. Fig. 2 shows the base-plate rotating and winding the tape on to the boss 7 and the roller 8. The base-plate 6 may be removed from the machine when the last loop has been disengaged from the magazine. To transfer the tape from the base-plate to the magazine both capstans draw the tape off the base-plate and feed it into the magazine. The speed of the capstan 2 is controlled by the speed of the capstan 3. Air jets 1a are provided to clear tape loops from the inlets. In a modification the boss 7 and roller 8 may be replaced by two rollers symmetrically disposed on either side of the centre of the base-plate.

Abstract: 264,125. Pharmagans Pharmaceutisches Institut L. W. Gans Akt.-Ges. Jan. 5, 1926, [Convention date]. Compound bottles and jars.-Ampoules for the separate storage of the ingredients of unstable solutions, such as medical solutions for injection. comprise a glass container for the solvent and a separate inner container for the solute so mounted that it may be caused to fall into the solvent by movement of a rod or piston operated from outside the main container. In the form shown in Fig. 1 an inner container e is mounted on a plunger d passing through the stopper c of an ampoule a and may be dislodged by upward movement of the plunger. In a modification, Fig. 2, the inner container e is mounted on a plunger m housed in a recess in the stopper c fitted with a packing sleeve i of soft rubber and held in place by a shackle j. The stopper c is formed of hard rubber, celluloid, glass, Bakelite, or the like. A second outlet n from the ampoule is closed by an elastic membrane o so that the needle of a hypodermic syringe may be passed therethrough for charging the syringe, the hole so formed being self-closing on withdrawal of the needle. In a further modification, the inner container is mounted on the lower end of the stopper and is dislodged by downward movement of the plunger. The Specification as open to inspection under Sect. 91 (3) (a) describes also a form in which the plunger has two enlarged portions of different diameters housed in a correspondingly shaped opening in the stopper which is covered externally by a capsule or membrane of celluloid or rubber through which the handle of the plungers passes. Fig. 5 (Cancelled) shows a form of construction in which a metal plunger m working in a metal stopper c is formed with grooves fitted with rubber packing rings u, v, and the stopper and plunger are covered by an elastic rubber membrane w so that the plunger may be operated without breaking or removing the membrane. It is stated also that the various ampoules and stoppers may be made of porcelain. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,068,996. Continuous casting-machines. MANNESMAN A.G. May 4, 1964 [May 3, 1963], No. 18511/64. Heading B3F. In a method of continuous casting in which the casting moves downwardly through a straight or curved mould and is discharged laterally through a curved roller cradle, the bending or straightening of the casting is commenced while the casting is still only partly solidified and is carried out in sub-divided stages, the degree of deformation in successive stages being less than that which is harmful to the material. When casting through a curved mould, the casting is brought into the horizontal through successive stages (a-b, b-c, c-d, d-e) of increasing radii. In a modification, when casting through a straight mould the casting is first bent through a curved path of successive sections of decreasing radii. and then into the horizontal through a curved path of successive sections of increasing radii.
