Abstract
Abstract An arrangement for developing photomaterials has a rotatable drum arranged to accommodate a photomaterial, a plurality of vessels for various treatment fluids, an arm having a free end rotatably connectable with the drum and turnable together with the latter between a substantially horizontal initial position for supplying a treatment fluid from one of the vessels into the drum for treatment of the photomaterial and an inclined emptying position for discharging a used treatment fluid from the drum after the treatment, a guide arranged so that the vessels are located near one another in a stack and displaceable to the drum for filling the latter, a stepping element including the arm and arranged to displace the vessel of the stack by a respective one of the vessels in a cycle with the turning of the arm, and a lifting member provided on the arm and arranged so as to upwardly tilt the vessel which has been displaced to the drum, to its pouring position of the treatment fluid.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
170 words
An arrangement for developing photomaterials, comprising a rotatable drum arranged to accommodate a photomaterial; a plurality of vessels for various treatment fluids; an arm having a free end rotatably connectable with said drum and turnable together with the latter between a substantially horizontal initial position for suppplying a treatment fluid from one of said vessels into said drum for treatment of the photomaterial, and an inclined emptying position for discharging a used treatment fluid from said drum after the treatment; guide means arranged so that said vessels are located near one another in a stack and displaceable to said drum for filling the latter; stepping means in which said arm forms a drive part and arranged to displace said vessels of said stack by a respective one of said vessels in cycle with the turning of said arm; and a lifting member provided on said arm and arranged so as to upwardly tilt the vessel which has been displaced to said drum, to its pouring position of the treatment fluid.
Claim 2
Dependent Claim
170 words
An arrangement for developing photomaterials, comprising a rotatable drum arranged to accommodate a photomaterial; a plurality of vessels for various treatment fluids; an arm having a free end rotatably connectable with said drum and turnable together with the latter between a substantially horizontal initial position for suppplying a treatment fluid from one of said vessels into said drum for treatment of the photomaterial, and an inclined emptying position for discharging a used treatment fluid from said drum after the treatment; guide means arranged so that said vessels are located near one another in a stack and displaceable to said drum for filling the latter; stepping means in which said arm forms a drive part and arranged to displace said vessels of said stack by a respective one of said vessels in cycle with the turning of said arm; and a lifting member provided on said arm and arranged so as to upwardly tilt the vessel which has been displaced to said drum, to its pouring position of the treatment fluid.
Claim 3
Dependent Claim
65 words
An arrangement as defined in claim 1; and further comprising an inlet pipe and a pouring funnel which opens into the former and is arranged so that in said substantially horizontal initial position the treatment fluid flows from said one vessel into said drum through said inlet pipe, and when said stack has been displaced by the respective vessel the latter approaches said pouring funnel.
Claim 4
Dependent Claim
65 words
An arrangement as defined in claim 1, wherein said vessels have vessel openings, said guide means having an axis; and further comprising a plurality of travellers arranged at the side of said vessel openings so that said vessels are held by said travellers on said guide means, said travellers being displaceable along said axis of said guide means and also tiltable relative to said axis.
Claim 5
Dependent Claim
43 words
An arrangement as defined in claim 1, wherein said vessels have vessel openings and vessel bottoms, said guide means being arranged to determine a lower position of each of said vessels in which its vessel bottom is located lower than its vessel opening.
Claim 6
Dependent Claim
51 words
An arrangement as defined in claim 3, wherein said guide means includes an upper guide member provided for longitudinal displacement of said travellers and also serving as a tilting axle for said travellers, and a lower guide member for slidingly supporting a lower end region of said vessels in said stack.
Claim 7
Dependent Claim
28 words
An arrangement as defined in claim 1; and further comprising force loading means arranged to act in one direction and to displace said stack on said guide means.
Claim 8
Dependent Claim
45 words
An arrangement as defined in claim 1, wherein said stack is displaceable along a predetermined displacement path, said lifting member in said initial position of said arm extending into said displacement path and forming a stop for a vessel which follows the upwardly tilted vessel.
Claim 9
Dependent Claim
48 words
An arrangement as defined in claim 7; and further comprising a fixed stop located before said lifting member relative to said displacement path and arranged to stop said arm of said stack in said emptying position and to place a next upwardly tilted vessel to said lifting member.
Claim 10
Dependent Claim
18 words
An arrangement as defined in claim 1, wherein said lifting member is mounted directly on said turnable arm.
Claim 11
Dependent Claim
36 words
An arrangement as defined in claim 2; and further comprising an outlet pipes located under said funnel for said drum, said lifting member being fork-shaped and having a fork opening for extending said outlet pipe therethrough.
Claim 12
Dependent Claim
35 words
An arrangement as defined in claim 10, wherein said inlet pipe has a pipe space which in said initial position communicates with said pouring funnel and in said emptying position communicates with said outlet pipe.
Claim 13
Dependent Claim
33 words
An arrangement as defined in claim 2, wherein said inlet pipe is also turnable and has an end which is located at the side of said funnel and serves as a rotary valve.
Claim 14
Dependent Claim
27 words
An arrangement as defined in claim 1, wherein said guide means is formed linearly so as to provide a linear displacement of said vessels in said stack.
Claim 15
Dependent Claim
31 words
An arrangement as defined in claim 1, wherein said guide means is formed as an annularly closed merry-go-round so as to provide an annular displacement of said vessels in said stack.
Claim 16
Dependent Claim
57 words
An arrangement as defined in claim 1; and further comprising means forming a tempering bath, and an attachment provided on said means and formed so that said guide means for displacing said vessels, said turnable arm for turning said drum, and said lifting member for tilting a respective one of said vessels are arranged on said attachment.
