Abstract
Abstract A magnetic ticket validator includes a housing having a ticket receiving channel for receiving a coded magnetic ticket with a heat source adjacent the channel in the form of a flashbulb, with an exposure slot exposing a magnetic strip on the ticket to the flashbulb and a coded masking tape, for imposition of a binary code on the magnetic strip upon initiation of the flashbulb. The heat from the flashbulb heats selected portions of the magnetic tape exposed by the mask.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
74 words
A validator mechanism for magnetic tickets comprising in combination: a housing, a channel in said housing for receiving a ticket, a source of instantaneous heat disposed adjacent said channel, said source of heat being sufficient to raise the temperature of a magnetic ticket in said channel to the Curie point, and masking means for masking selected areas of a ticket in said channel from said heat source for defining a code on said ticket.
Claim 2
Dependent Claim
74 words
A validator mechanism for magnetic tickets comprising in combination: a housing, a channel in said housing for receiving a ticket, a source of instantaneous heat disposed adjacent said channel, said source of heat being sufficient to raise the temperature of a magnetic ticket in said channel to the Curie point, and masking means for masking selected areas of a ticket in said channel from said heat source for defining a code on said ticket.
Claim 3
Dependent Claim
15 words
The validator mechanism of claim 1, wherein said mask includes areas defining a binary code.
Claim 4
Dependent Claim
13 words
The validator mechanism of claim 2, wherein said mask is a photo negative.
Claim 5
Dependent Claim
14 words
The validator of claim 1, wherein said source of heat is a flash unit.
Claim 6
Dependent Claim
27 words
The validator of claim 4, wherein said flash unit includes trigger means positioned in said channel for engagement by a ticket inserted into position in said channel.
Claim 7
Dependent Claim
17 words
The validator of claim 5, wherein said flash unit includes a xenon bulb disposed adjacent said channel.
Claim 8
Dependent Claim
34 words
The validator of claim 1, wherein said channel includes an exposure slot exposing a selected strip of a ticket disposed adajcent to said heat source, and said mask is disposed over said exposure slot.
Claim 9
Dependent Claim
18 words
