Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
A portable, modular control means comprising: multiple power relays each having a control winding and multiple contacts whereby the contacts of said relays are connected to a source of electrical power and to respective load means; and multiple sets of switch means at locations remote from one another, whereby each set of said sets controls the switching state of all of said contacts from all of said locations of said switch means by said switch means controlling the application of said power to and removal of said power from said control windings of said relays.
Claim 2
Dependent Claim
95 words
A portable, modular control means comprising: multiple power relays each having a control winding and multiple contacts whereby the contacts of said relays are connected to a source of electrical power and to respective load means; and multiple sets of switch means at locations remote from one another, whereby each set of said sets controls the switching state of all of said contacts from all of said locations of said switch means by said switch means controlling the application of said power to and removal of said power from said control windings of said relays.
Claim 3
Dependent Claim
18 words
A portable, modular control means as claimed in claim 1, wherein: said sets are mounted within a housing.
Claim 4
Dependent Claim
25 words
A housing, as claimed in claim 2, wherein: a clip is mounted on an exterior side of said housing for attachment to a support means.
Claim 5
Dependent Claim
39 words
A portable, modular control means as claimed in claim 1, wherein: a step-down transformer having a primary winding and a secondary winding whereby said primary winding is connected, in series, to said switch means and to said control windings.
Claim 6
Dependent Claim
30 words
A portable, modular control means as claimed in claim 1 wherein: said switch means are not only located remote from one another but are also located remote from said relays.
Claim 7
Dependent Claim
94 words
A portable, modular control means for a duplex outlet receptacle, comprising: two power relays each having a control winding and multiple contacts whereby the contacts of said relays are connected to a source of alternating electrical power and to respective load means; and two pairs of switch means at locations remote from one another whereby each set of said pairs controls the switching state of each contact from both locations by said switch means controlling the application of said power to and the removal of said power from said control winding of said relays.
Claim 8
Dependent Claim
94 words
A portable, modular control means for a duplex outlet receptacle, comprising: two power relays each having a control winding and multiple contacts whereby the contacts of said relays are connected to a source of alternating electrical power and to respective load means; and two pairs of switch means at locations remote from one another whereby each set of said pairs controls the switching state of each contact from both locations by said switch means controlling the application of said power to and the removal of said power from said control winding of said relays.
Claim 9
Dependent Claim
19 words
A portable, modular control means as claimed in claim 6, wherein: said switch means are mounted within a housing.
Claim 10
Dependent Claim
25 words
A housing, as claimed in claim 7, wherein: a clip is mounted on an exterior side of said housing for attachment to a support means.
Claim 11
Dependent Claim
48 words
A portable, modular control means as claimed in claim 6, wherein: a step-down transformer having a primary winding and a secondary winding whereby said primary winding is connected to said source and said secondary winding is connected, in series, to said switch means and to said control windings.
Claim 12
Dependent Claim
30 words
A portable, modular control means as claimed in claim 6, wherein: said switch means are not only located remote from each other but are also located remote from said relays.
