Title: Starting switch for single-phase induction motors
IPC: H02P1/42
Filed: 1961-04-20
Abstract: 950,332. Thermal switches. ELLENBERGER & POENSGEN G.m.b.H. April 20, 1961 [April 23, 1960; April 15, 1961], No. 14365/61. Heading H2B. A hot wire starting switch for a single phase induction motor comprises a first contact 22 arranged for connection to a starting winding of the motor; a second contact 22 movable into engagement with the first by an angled lever 18 pivoted at 19 and attached at 25 to the free end of a hot wire 26 heated by current flowing to the motor; and a spring 30 tending to stretch the wire. The contact 24 is mounted on a spring blade 23 riveted to a terminal 8; contact 22 and the clamped end of the wire 26 make contact with further terminals 7 and 9 respectively. Current flows to the main winding of the motor through terminals 9, 7 and the wire 26. Heavy initial currents cause the wire to expand allowing spring 30 to close the contacts 22, 24; current then flows through terminal 8 to the starting winding. As motor speed increases the current falls and wire 26 contracts to reopen the contacts, de-energizing the starting winding. If the motor is overloaded, current again rises causing the contacts to close; the starting winding then provides a torque support. In the event of excessively high currents causing the wire to overheat contact 22 is moved sufficiently far to cause contact 24 to engage a further contact 39 to temporarily short circuit the wire and allow it to cool. The tension in wire 26 is adjustable by a screw 37. In a second embodiment (Fig. 14) the second contact 59 is snap acting and contacts 58, 59 are normally closed to supply current to the starting winding, these contacts being opened, by expansion of the wire, a short while after starting and maintained open by the normal current. Excessive currents cause the angled lever 66 to move sufficiently far for screw 87 to engage a contact 86 and short circuit the wire 26. The contacts may be of normally open construction as in the first embodiment (Fig. 19, not shown).

Moulding pipes and tubes; moulding pulp.- Comprises apparatus for moulding pipe sections of the type involving inner and outer moulds each capable of expansion and contraction and consists in the provision of an inner mould positively rotatable for trowelling the inner surface of the pipe. The outer mould is composed of sections 15 supported on pins 14 extending from radial plungers 8 guided in upper and lower plates 4 clamped upon columns 1. The plungers 8 aremoved inwardly, against the action of springs, by chordal cams 10 on rings 11 oscillated by plungers in hydraulic cylinders 19 acting through levers 25 and links 27. The inner mould comprises segments 49 supported between upper and lower rings 51, 50 carried by a tube 36 suspended from a framework 31, the sections being moved inwardly by springs and outwardly by wedge blocks 48 connected to a rod 42 controlled by a handlever 44. Rotation may be imparted to the tube 36 through a pulley 41, shaft 40 and gears 38, 37. The surfaces of the sections 15 are formed of grids 16, Fig. 7, having narrow slits 17 leading to drainage channels 18; similarly the inner sections 49 are furnished with grids 57 having slits 58 leading to drainage channels 58'. A head 33, Fig. 2, and cap 34 constitute the upper end of the mould and house an annular plunger 59 suspended from a crosshead 61 operable by an hydraulic piston 65. In operation, a reinforcement 81 is assembled on a base-ring 77 and surmounted by a top ring 73 and the structure aligned with the moulds and raised thereinto by a platform 82 carried by au hydraulic piston 83, the inner mould being previously contracted and the outer mould expanded. The inner mould is then expanded and the piston 65 raised causing spring fingers on the plunger 59 to engage, and lift the ring 73 above a filling-opening 93, Fig. 5, fitted with an hvdraulic closure 94. Material is then run into the mould from a hopper 92, the closure 94 being withdrawn, after which the closure, is advanced, the plunger 59 and ring 73 are forced down by operation of the piston 65 and the outer mould contracted to compress the material. After compression, the inner mould is first-contracted, then the tuba 36 is rotated and the mould gradually expanded to effect the travelling operation. The mould sections are then withdrawn and the pipe lowered from the mould on the platform 82. Washing devices are provided for the mould drainage channels and mould surfaces. The lower portions of the columns 1 are threaded to receive nuts 109 upon which the members 4 can be raised into operative position or lowered for transport. By clamping the upper plate 4 and lowering the lower one access may be had to the outer mould parts for repair &c.
