Abstract
Abstract An operative location or station for the examination of patients by means of X-rays, including a patients' support bed which is tiltable about a horizontal, vertically adjustable pivoting axis; including an X-ray exposure or filming installation having a picture plane oriented in parallel with the patients' support bed; a so-called overhead X-ray tube which is directed towards the picture plane; and an automatic developing arrangement for the sheets of film. The operative location is provided with transport means for the exposed film sheets which are compensatory for the vertical adjustability and inclinability of the X-ray exposure installation between the picture plane and the automatic developing arrangement, the latter of which is immovably located on the floor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
In an operative location for the examination of patients by X-rays, including a patient's support bed tiltable about a horizontal, vertically adjustable pivoting axis; an X-ray exposure installation having a picture plane extending in parallel with said patients' support bed; an overhead X-ray tube oriented towards said picture plane; and an automatic developing arrangement for X-ray film sheets, the improvement comprising: conveying means for the exposed X-ray film sheets compensating for the elevational adjustability and inclinability of said X-ray exposure installation being disposed intermediate said picture plane and said automatic developing arrangement, said developing arrangement being immovably positioned on the floor of said location, said conveying means including a conveying run for said exposed film sheets connected to said X-ray exposure installation and being jointly tiltable therewith about said pivoting axis; and at least one intermediate film sheet storage magazine adapted to be selectively aligned with said conveying run and said developing arrangement, said intermediate magazine being vertically adjustable and rotatable about a support axis extending in parallel with said pivoting axis.
Claim 2
Dependent Claim
172 words
In an operative location for the examination of patients by X-rays, including a patient's support bed tiltable about a horizontal, vertically adjustable pivoting axis; an X-ray exposure installation having a picture plane extending in parallel with said patients' support bed; an overhead X-ray tube oriented towards said picture plane; and an automatic developing arrangement for X-ray film sheets, the improvement comprising: conveying means for the exposed X-ray film sheets compensating for the elevational adjustability and inclinability of said X-ray exposure installation being disposed intermediate said picture plane and said automatic developing arrangement, said developing arrangement being immovably positioned on the floor of said location, said conveying means including a conveying run for said exposed film sheets connected to said X-ray exposure installation and being jointly tiltable therewith about said pivoting axis; and at least one intermediate film sheet storage magazine adapted to be selectively aligned with said conveying run and said developing arrangement, said intermediate magazine being vertically adjustable and rotatable about a support axis extending in parallel with said pivoting axis.
Claim 3
Dependent Claim
57 words
An operative location as claimed in claim 1, comprising a guide bracket being mounted on said conveying run; and a guide element being fastened to said intermediate magazine adapted for operative engagement with said guide bracket whereby said intermediate magazine is rotated and centered into the respective inclined position of said conveying run upon approaching the latter.
Claim 4
Dependent Claim
38 words
An operative location as claimed in claim 2, comprising coupling means for effecting movement of said intermediate magazine during changes in position of said X-ray exposure installation, said coupling means interconnecting said conveying run and said intermediate magazine.
Claim 5
Dependent Claim
26 words
An operative location as claimed in claim 1, comprising a collecting magazine being located directly preceding said automatic developing arrangement for receiving said exposed film sheets.
Claim 6
Dependent Claim
81 words
An operative location as claimed in claim 1, said conveying run including a first conveying run for exposed film sheets being directly exposed to the X-rays, and a separate second conveying run extending in parallel to said first conveying run for conveying small-sized film sheets being disposed to an image-intensifying output fluorescent screen, said intermediate magazine having support surfaces coordinated with the varying film sizes, said support surfaces being adapted to be coupled in synchronism with their respective associated conveying runs.
Claim 7
Dependent Claim
26 words
An operative location as claimed in claim 1, comprising pressure roll means for retaining said film sheets in said intermediate magazine independently of the positioning thereof.
Claim 8
Dependent Claim
17 words
An operative location as claimed in claim 4, said collecting magazine including a film sheet withdrawal arrangement.
Claim 9
Dependent Claim
22 words
An operative location as claimed in claim 7, said film sheets being withdrawn from said collecting magazine in an exposure series sequence.
Claim 10
Dependent Claim
152 words
In an operative location for the examination of patients by X-rays, including a patients' support bed tiltable about a horizontal, vertically adjustable pivoting axis; an X-ray exposure installation having a picture plane extending in parallel with said patients' support bed; an overhead X-ray tube oriented towards said picture plane, and an automatic developing arrangement for X-ray film sheets, the improvement comprising: conveying means for the exposed X-ray film sheets compensating for the elevational adjustability and inclinability of said X-ray exposure installation being disposed intermediate said picture plane and said automatic developing arrangement, said developing arrangement being immovably positioned on the floor of said location; a light-tight covered chute having a U-shaped feed hopper being located below said pivoting axis and leading towards said automatic developing arrangement; a plurality of nozzles being locaated in the walls of said chute and of said feed hopper; and means for supplying pressurized air to said nozzles.
Claim 11
Dependent Claim
152 words
In an operative location for the examination of patients by X-rays, including a patients' support bed tiltable about a horizontal, vertically adjustable pivoting axis; an X-ray exposure installation having a picture plane extending in parallel with said patients' support bed; an overhead X-ray tube oriented towards said picture plane, and an automatic developing arrangement for X-ray film sheets, the improvement comprising: conveying means for the exposed X-ray film sheets compensating for the elevational adjustability and inclinability of said X-ray exposure installation being disposed intermediate said picture plane and said automatic developing arrangement, said developing arrangement being immovably positioned on the floor of said location; a light-tight covered chute having a U-shaped feed hopper being located below said pivoting axis and leading towards said automatic developing arrangement; a plurality of nozzles being locaated in the walls of said chute and of said feed hopper; and means for supplying pressurized air to said nozzles.
