Abstract
Abstract In an arrangement of photoflash lamps, one or more of the lamps has a heat-deformable plastic control pin positioned adjacent thereto so as to become deformable due to heat generated when the lamp is flashed. The control pins are provided with specially shaped deformation zones, blackened if desired, to more readily absorb heat and become deformed when the associated lamp is flashed. The control pins are spring-loaded by a mechanism for controlling a function such as switching of electrical connections from one lamp to another as they become flashed, or for actuating indicator means for indicating whether a lamp has been flashed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
64 words
A photoflash arrangement comprising a photoflash lamp and a heat-deformable control pin, means supporting said control pin at an end thereof whereby at least a portion of the control pin is adjacent to and extends alongside said lamp, said control pin being made of a material that softens and becomes longitudinally deformable when heated from heat generated by the flashing of said photoflash lamp.
Claim 2
Dependent Claim
64 words
A photoflash arrangement comprising a photoflash lamp and a heat-deformable control pin, means supporting said control pin at an end thereof whereby at least a portion of the control pin is adjacent to and extends alongside said lamp, said control pin being made of a material that softens and becomes longitudinally deformable when heated from heat generated by the flashing of said photoflash lamp.
Claim 3
Dependent Claim
64 words
A photoflash arrangement comprising a photoflash lamp and a heat-deformable control pin, means supporting said control pin at an end thereof whereby at least a portion of the control pin is adjacent to and extends alongside said lamp, said control pin being made of a material that softens and becomes longitudinally deformable when heated from heat generated by the flashing of said photoflash lamp.
Claim 4
Dependent Claim
64 words
A photoflash arrangement comprising a photoflash lamp and a heat-deformable control pin, means supporting said control pin at an end thereof whereby at least a portion of the control pin is adjacent to and extends alongside said lamp, said control pin being made of a material that softens and becomes longitudinally deformable when heated from heat generated by the flashing of said photoflash lamp.
Claim 5
Dependent Claim
50 words
An arrangement as claimed in claim 1, in which said control pin is provided with a deformation zone intermediate the ends thereof, said deformation zone being blackened so as to more readily absorb heat from said lamp when flashed thereby permitting deformation of said control pin at said deformation zone.
Claim 6
Dependent Claim
41 words
An arrangement as claimed in claim 1, in which said control pin is provided with a deformation zone intermediate the ends thereof comprising a narRowed cross-section of the control pin at a position to receive heat from said lamp when flashed.
Claim 7
Dependent Claim
45 words
An arrangement as claimed in claim 1, in which said control pin is provided with a deformation zone intermediate the ends thereof comprising a flattened and widened section thereof facing broadside toward said lamp at a position to receive heat from said lamp when flashed.
Claim 8
Dependent Claim
22 words
An arrangement as claimed in claim 4, in which said deformation zone is blackened on the side thereof facing toward said lamp.
Claim 9
Dependent Claim
25 words
An arrangement as claimed in claim 1, in which said support means comprises means attaching said control pin at an end thereof to said lamp.
Claim 10
Dependent Claim
38 words
An arrangement as claimed in claim 1, including housing means containing said lamp and control pin, and in which said support means comprises means carried by said housing means for supporting said control pin near an end thereof.
Claim 11
Dependent Claim
39 words
An arrangement as claimed in claim 1, including a reflector positioned with respect to said lamp for reflecting light therefrom, and in which said support means comprises means attaching said control pin at an end thereof to said reflector.
Claim 12
Dependent Claim
29 words
An arrangement as claimed in claim 1, including a reflector positioned with respect to said lamp for reflecting light therefrom, said control pin being integrally formed with said reflector.
Claim 13
Dependent Claim
51 words
An arrangement as claimed in claim 9, in which said reflector is contoured to have a portion thereof relatively straight and adjacent to said lamp alongside thereof, said reflector being provided with a pair of mutually parallel slots extending into said portion of the reflector and defining said control pin therebetween.
Claim 14
Dependent Claim
108 words
A photoflash arrangement comprising a plurality of elongated photoflash lamps positioned with their axes mutually parallel to one another, a plurality of heat-deformable control pins each supported at an end thereof and respectively positioned adjacent to and alongside individual ones of said lamps, the axes of said control pins being mutually parallel to each other and to said axes of the lamps, each of said control pins being made of a material that softens and becomes longitudinally deformable when heated from heat generated when the individual adjacent lamp is flashed, the remaining end of each control pin being adapted to become movable when the control pin becomes deformable.
Claim 15
Dependent Claim
108 words
A photoflash arrangement comprising a plurality of elongated photoflash lamps positioned with their axes mutually parallel to one another, a plurality of heat-deformable control pins each supported at an end thereof and respectively positioned adjacent to and alongside individual ones of said lamps, the axes of said control pins being mutually parallel to each other and to said axes of the lamps, each of said control pins being made of a material that softens and becomes longitudinally deformable when heated from heat generated when the individual adjacent lamp is flashed, the remaining end of each control pin being adapted to become movable when the control pin becomes deformable.
Claim 16
Dependent Claim
47 words
An arrangement as claimed in claim 11, in which each said control pin is provided with a deformation zone intermediate the ends thereof at a position to receive heat from the individual adjacent lamp when flashed thereby permitting deformation of the control pin at said deformation zone.
Claim 17
Dependent Claim
28 words
An arrangement as claimed in claim 12, in which each of said deformation zones is shaped to have a substantially flat surface facing toward said individual adjacent lamp.
