Title: Electromagnetic motor
IPC: H02K37/04
Filed: 1975-06-20
Abstract: 1503199 Stepping motors ELMEG ELEKTRO-MECHANIK GmbH 20 June 1975 [20 June 1974] 26294/76 Heading H2A An electric motor has a magnetically conductive movable member 8, Fig. 1, with polepieces a, o, -a . . . equispaced in its direction of movement and of length in said direction equal to said spacing, a stator 7 having at least three polepieces 2, 3, 4, spaced apart in said direction with a middle polepiece 3 having a length equal to that of the polepieces of member 8, and polepieces 2, 4, being spaced from polepiece 3 in said direction by half the length of polepiece 3 and each having a length in said direction of half that of polepiece 3, the stator polepieces 2, 3, 4 being premagnetized or premagnetizable so that 2, 4 are of one magnetic polarity and 3 is of the other, and a winding 6 on the stator 7 to influence the magnetization of polepieces 2, 3, 4 to cause stepping of member 8. The member 8 may be rotated or moved linearly. The stator 7 may be E-shaped with excitation coils 5, 6 on poles 2 and 4 and a permanent magnet 1 in pole 3. Magnet 1 may be shunted by iron paths 13, 14 having non-magnetic gaps 15, 16. Energization of coil 6 with a pulse of appropriate polarity so that the excitation Wi increases from 0 through Wi 1  to Wi 2  and back to 0 causes element 8 to move through the positions shown in Fig. 1 by one step to the right. Energization of coil 5 causes stepping to the left. Alternatively coils 5 and 6 may be connected in series, the stepping direction then depending on the polarity of the energizing pulse. In a numbered roller-type of pulse counter, which may be an up/down counter, the motor drives the rollers and has a rotor (18), Fig. 9 (not shown), forming at least part of one of the numerical indicia carrying rollers. In a self-starting synchronous motor, Fig. 10, a rotor 21 has poles 24, 25 and is rotated in the clockwise direction by two stators 26, 27 on opposite sides of the rotor axis and laterally offset from one another, each stator being constructed like stator 7 in Fig. 1 and having one or two excitation windings 6<SP>1</SP>, 6<SP>11</SP>. Stators 26 and 27 are excited by the positive and negative half-waves respectively of a rectified alternating voltage.

Title: Improvements in and relating to electric power distribution systems
IPC: H02H7/26
Filed: 1920-09-14
Abstract: 172,731. British Thomson - Houston Co., Ltd., and Trencham, H. Sept. 14, 1920. Protective arrangements.-In a power distribution system a spare cable is laid additional to the supply cables and of the same capacity as each of them, the space cable serving while the system is sound as a pilot wire in a Merz-Price type of protective system, and on fault to earth as a substitute cable which by means of switch devices replaces the faulty cable which in turn serves as the pilot wire. In the three-phase arrangement shown, employing lead-sheathed cables, the main cables 1, 2, 3 are provided with isolating switches 12 and change-over switches 13 which enable the spare cable 4 by means of its switch 13 to be substituted for any of the main cables and the faultv cable isolated. Current transformers 5 are arranged at each end of the system and connected as shown. To ensure that only faults within the section protected will operate the switches, the transformer group at one end is connected to that at the other through relays 9 by means of the spare cable, the return circuit being through earth. In the case of feeders where it is possible for faults to occur between phases, two additional transformers are arranged at each end with their secondaries connected in series and with the secondary systems of the earth fault protection transformers. The improvements are applicable also to single-phase and two-phase systems.

Filed: 1946-09-04
Abstract: 616,401. Lathes. BECHLER, A. Sept. 4, 1946, No. 26527. Convention date, June 17. [Class 83 (iii)] An oscillating tool-holder for drilling and tapping on automatic lathes is characterised in that the controlling lever 18, directed by a grooved cam 22, is made in two parts 17 and 19 articulate with one another so that any relative displacement produced between them will disconnect the cam-shaft 23 from the driving power. The two parts 17, 19 are joined by a pivot 38 and a spring-pressed plunger 35. If jamming of the tools occurs, the plunger is forced outwards, thus turning a lever arm 33 and releasing a clutch 28.

The halflines are adhesively sealed together and wrapped in a jacket 33, of, for example, plastics and fibre glass, and a rubber integument 36. Each clapper may have a second guide entry (130). As an alternative to tipping the fingers 34 with tungsten a dish-shaped article (Fig. 8, not shown) is positioned around and in contact with the contact 29, so that any arcs are struck between the plug-contact 9 and the edge of a hole (39) in the article through which the contact 9 passes.

Abstract: 174,569. Griscom-Russell Co., (Assignees of Jefferson, C.). Jan. 25, 1921, [Convention date]. Rectifiers. - Petroleum or other vapours to be fractionated are admitted by an inlet 8 to a lower shell 2 and pass upwards through pipes 26, Fig. 1, open at their lower ends and leading to pipes 11 which pass through the upper shell 1, and are cooled by a cooling-agent circulated between openings 9, 10 and caused to take a circuitous course bv a spiral baffle 20. The upper ends of the tubes 11 are secured to a hollow head 15 capable of slight movement in the casing 1 so as to allow of expansion of the tubes, and having a vapour outlet 17. The heavy fractions condensed from the vapours are withdrawn through an outlet 7. Instead of two sets of pipes, the pipes 11 may project into the lower casing, or the lower casing may contain a spiral baffle 30, Fig. 4, down which the liquid dripping from the pipes 11 will flow in countercurrent to the vapours. The amount of the vapour which is condensed is varied by varying the rate of flow or the temperature of the cooling-agent which is passed through the shell 1. The baffle 20 may be constructed as described in Specification 176,753, [Class 64 (iii), Surface apparatus &c.].

[Also in Group XI] Thermoplastic material, such as polythene, which has a low power factor at frequencies employed in high-frequency dielectric heating apparatus, is welded by applying to the material a tool which is heated by electromagnetic induction so as to cause local softening of the material, the tool being subsequently cooled to solidify the material of the weld while maintaining the weld under sufficient pressure to cause adhesion. Two sheets of material may be welded together between a pair of opposed metal jaws, each arranged in the field of a work coil capable of being supplied with highfrequency energy; when the material is softened, the electrical supply is cut off and the jaws are cooled by cooling fluid such as water which is passed through ducts in the jaws close to the working surfaces, the material being maintained under sufficient pressure to cause adhesion.

The other end of link 72 is pivoted, in the usual manner, to the mid-point on the link 53 which at its outer end carries the hydraulically operated gripper jaws 81, 82, and is pivotally connected at its inner end 52 to a sleeve 51 slidably mounted on the vertical column 50, the sleeve 51 being guided on the column 50 by a roller 62, on the sleeve 51, engaging one of a number of splineways 60 axially arranged on the column 50. The splineways 60 terminate in inclined cam ramps 65, 66 whereby when the sleeve 51 is moved by a linear motor 64 therein to the extreme upper end of the column, to fully retract the straight-line linkwork arm 53, 72 to radially inwardly move the gripper jaws 81, 82 from one work station, the sleeve roller 62 engages the appropriate cam ramps 66 to angularly index the sleeve to the next axial splineway 60 to align the straight-line linkwork arm 53, 72 with the next work station, after which downward movement of the sleeve 51 on the column again extends the straight-line linkwork arm 53, 72 to move the gripper jaws 81, 82 radially outwards to this next work station. As shown, the angular indexing of the arm is in progressive steps in one direction. Alternatively, Figs. 3 and 4 (not shown) the indexing of the arm may be controlled by a pre-set needle (23) to move in one and/or other direction as required. The straightline motion linkwork arm 53, 72 is reinforced by a further link 54 pivotally arranged to form a parallelogram with the link 53.
