US Patent:

42388791, Dec 16, 1980

Filed:

Aug 16, 1978

Appl. No.:

5/933992

Inventors:

Cyril P. Zurlinden - La Crescenta CA
Charles W. Howe - Sunland CA

International Classification:

H01F 4102

US Classification:

29705

Abstract:

A method for manually assembling an inductor and calibrating it, and apparatus to facilitate practice of the method. Laminations are manually inserted into the ends of a hollow core of a wire-wound bobbin to build up a right hand stack of laminations and a left hand stack of laminations. Manual insertion of the laminations is facilitated by use of a stacking block which includes upright indexing posts to promote registration of the laminations. The left and right laminations are so stacked that an oversize air gap is included between the right hand stack and the left hand stack. After all the laminations have been stacked, the inductor is placed on a calibrator bed to facilitate calibration. The calibrator bed includes first and second sets of jaws which are closed along orthogonal directions under control of an operator. Closure of the first set of jaws brings the laminations into registration.

Abstract:

A machine for removing a precut length of plastic pipe from an extrusion line, providing a bell on one end thereof, and providing a chamfer on the opposite end thereof. The pipe is received in a V-shaped trough along which it is longitudinally moved as it is delivered from the extruder. At predetermined intervals, a plurality of hydraulic pushers are actuated to move the pipe laterally from the trough onto a conveyor. The conveyor is indexed to a first position in which the axial location of the pipe is corrected and the end to be belled is heated. In a predetermined sequence of events, the conveyor is then indexed to a second position in which a belling plug is inserted into the heated end of the pipe; simultaneously, the opposite end of the pipe may be provided with an internal or external chamfer. When the conveyor is again indexed, the pipe is deposited onto a suitable system so that it may be conveyed to a shipping point.
