摘要:
An apparatus and method for placing magnet wire in the slots respectively defined by spaced, parallel blades of coil transfer apparatus which lie on an imaginary cylinder thereby to form a dynamoelectric machine field winding. The wire is pushed and simultaneously guided with a motion having components in at least two mutually perpendicular directions in a path having sections respectively aligned with at least two of the slots thereby to push the wire into the slots, the path also having sections respectively within and outside of the cylinder.

An apparatus and method for placing magnet wire in slots respectively defined by the blades of coil insertion apparatus which lie on an imaginary cylinder thereby to form a circular dynamoelectric machine field winding. The wire is pushed and simultaneously guided in a circular path which overlaps the cylindrical array of blades and which is aligned with the open ends of two of the slots whereby the wire is pushed into the two slots.

A pressure sensitive occupant sensor seat switch to detect the presence of an occupant in an automobile seat. A flat body formed of electrically insulating, resilient compressible material has one or more openings extending therethrough. A pad formed of electrically nonconductive compressible, resilient, inorganic or semiorganic material having discrete electrically conductive particles dispersed throughout occupies each opening. When the pad is uncompressed, the electrically conductive particles do not engage one another. When the pad is compressed, however, the electrically conductive particles engage one another and the pad becomes conductive. Electrical conductors on both sides of the insulating body make electrical contact to the pads so that the switch assembly controls a device connected to it when pressure is applied.
摘要:
An occupant sensor seat switch for detecting the presence of an occupant in an automobile seat. One or more resilient elastomeric pads having electrically conductive particles dispersed throughout are disposed between a base and a cover member to comprise a switch assembly. The resilient elastomeric pads are electrically conductive when compressed and nonconductive when in an uncompressed condition. Electrical connections are made to both sides of each pad so that when the pads are compressed the occupant sensor seat switch is rendered conductive.

An electromagnetic relay having an electromagnetic coil, frame and a pivotable armature. The frame is a generally C-shaped magnetizable member. One end of the frame is enlarged to increase air gap area while an armature is pivoted on the other end of the frame. A contact assembly connected directly to the armature provides for normally closed as well as normally open contacts and includes a post connected to the armature as well as contact carrying arms which slide on the post.

Terminating of an electrical conductor comprising a nonconductive core having conductive means on its surface and enclosed within an insulating jacket is effected by stripping the insulating jacket from at least one end of the conductor and casting an electrically conductive anchor member on the exposed end of the conductor, the anchor member being formed from a molten metal which shrinks upon solidification to provide an exceptionally secure mechanical and electrical bond between the core and the anchor member. The exposed end of the conductor may be kinked prior to the casting of the member.

Skein winding apparatus for wire coil winding machines has a rotatable arrangement of spaced projections for initially folding wire and has associated with it a device for twisting the folded wire intermediate the spaced elements. The apparatus forms interlocked wire skeins quickly.
摘要:
A protective device for protection of a refrigeration compressor from burnout caused by short cycling. A time delay means is provided which prevents the compressor motor from being started again until a predetermined time interval has elapsed after the system thermostat has opened. If a power failure should occur, the compressor motor is prevented from being started until a predetermined time interval has elapsed after power resumption to the refrigeration system.
摘要:
A relay construction having an energizable and deenergizable electrical winding operable to effect movements of an armature to and from a switch-closing position and wherein a non-conductive, elastomeric pad is interposed between the switch contacts, the elastomeric pad containing discrete, normally separated, electrically conductive particles dispersed therein in such quantity as to render the pad electrically conductive in response to compression thereof. The pad is mounted in such position as to be compressed in response to movement of the armature toward its switch-closing position. The elastomeric pad may be impregnated with or immersed in a lubricant and may form part of an electrically non-conductive, oil impervious seal or gasket for effect an environmental seal for the operating parts of the relay.
摘要:
A terminal for coupling electrical conductors formed of different materials and arranged in confronting, overlapping relation comprises a body formed of elastomeric, non-conductive material encircling at least one of the conductors and bearing against another of the conductors, the body containing a plurality of discrete, electrically conductive particles responsive to compression of the body to establish an electrically conductive path between the conductors. Force applying means acts on the body via a force distributing member which overlies a substantial portion of the length of the body so as to apply sufficient compressive force to the body to render the latter conductive.
