摘要:
A plurality of adjacent, aligned, shaped hollow uniform building components, each having four separate distinct key channels are assembled together with a plurality of friction fitting locking keys to accomplish at least three separate distinct locks which become uniform whole friction fitting structural buildings upon alignment of like side surfaces or like end surfaces of uniform building components, together with friction fitting insertion and alignment of one of four separate and distinct shaped uniform bridge keys, then friction fit insertion of the primary locking keys into and through the primary key channels of adjacent and/or abutting uniform building components and uniform bridge keys, thereby rapidly achieving the primary lock and key joint, being the primary finished bonded joint and the primary lock of this invention. The second and third separate distinct locks of this invention are accomplished using corner locking keys to achieve the corner lock and/or center bore hole locking keys to achieve the center bore hole lock. The interior or exterior of a friction fitting structural building is enhanced with other components, including transverse locking keys to form a transverse lock, and key channels may also contain building improvement components.

A magnetic trip mechanism is provided for an electrical switching apparatus. The magnetic trip mechanism includes a magnetic member, an armature having opposing first and second ends and first and second sides, an armature restraint and a biasing element. The armature moves among first and second positions corresponding to separable contacts of the electrical switching apparatus being tripped open and closeable, respectively. The armature restraint includes first and second portions. In the first position, the first side of the armature engages the magnetic member. In the second position, the second side of the armature engages the second portion of the armature restraint. The armature restraint and the biasing element comprise a sub-assembly, which is removably coupled to the magnetic member. After being removably coupled to the magnetic member, the biasing element is chargeable to bias the armature away from the first position toward the second position.

A cradle stop assembly is provided for a circuit breaker including an operating mechanism. The operating mechanism includes a pivotable movable contact arm and a cradle member which is movable between a latched position corresponding to separable contacts of the circuit breaker being closeable and an unlatched position corresponding to the separable contacts being tripped open. The cradle stop assembly includes a first member coupled to a portion of the operating mechanism, a second member disposed opposite the first member, and a generally planar stop plate extending between the first and second members. A first stop portion of the stop plate resists movement of the cradle member beyond a first predetermined position to avoid the cradle member undesirably interfering with the pivotable movable contact arm. A second stop portion resists the pivotable movable contact arm from undesirably pivoting beyond a second predetermined position.

An apparatus for securing a musical instrument to a waist belt that is attached relative to a performer's waist. The apparatus includes a first anchor for being attached to the waist belt; a second anchor for being attached to the musical instrument; and securing structure for removably securing the first anchor to the second anchor.

An electrical switching apparatus interface assembly provides remote actuation of the operating handle of a circuit breaker. The interface assembly includes the circuit breaker, a second switching apparatus, such as an actuating handle disposed in a remote location from the circuit breaker, a connector and an operating handle attachment including a handle-engaging segment for securely engaging the circuit breaker operating handle and an interfacing segment for receiving the connector. The actuating handle is operable between ON and OFF positions corresponding to ON and OFF positions, respectively, of the circuit breaker operating handle. The connector interfaces or links the circuit breaker to the actuating handle. In this manner, when the actuating handle is moved from the ON or OFF position, the connector moves the circuit breaker operating handle in a likewise manner.
