Abstract
Abstract A dispensing device, for dispensing reagent into an array of reaction wells (16) in a photographic recording apparatus, comprises an array of tubes (28) which are mounted in a support (23). The support (23) contains a common chamber (29) into which the tops of all the tubes (28) open. The chamber (29) is connected with atmosphere via an opening (32) which is sealable manually to retain liquid in the tubes (28) when the latter are immersed in a reservoir (40) and which is unsealed to dispense the liquid. The recording apparatus has a housing (10) closable at the top by part of the support (15) therethrough rests on a shutter (13) disposed above a photographic film holder (12). The plate (11) carries the reaction wells (16) in the holes (15).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
154 words
Recording apparatus comprising a holder for a multiplicity of reaction vessels, said holder comprising a plate (11) having an array of holes (15) therein for receiving an array of reaction vessels (16), a housing (10) for receiving the holder, said housing (10) being sealed to prevent entry of stray light and being fitted with an openable cover (24, 249), means (12) for holding a photographic film adjacent the underside of the plate (11), and a removable shutter (13) for interposition between the film and said plate (11), said removable shutter (13) being movable between a closed position and an opened position, in which latter position the film is exposed in use, and said plate (11) being arranged (a) to rest on and be supported by said shutter (13) when the latter is in its closed position and (b) to drop towards the photographic film when the shutter (13) is moved to its opened position.
Claim 2
Dependent Claim
154 words
Recording apparatus comprising a holder for a multiplicity of reaction vessels, said holder comprising a plate (11) having an array of holes (15) therein for receiving an array of reaction vessels (16), a housing (10) for receiving the holder, said housing (10) being sealed to prevent entry of stray light and being fitted with an openable cover (24, 249), means (12) for holding a photographic film adjacent the underside of the plate (11), and a removable shutter (13) for interposition between the film and said plate (11), said removable shutter (13) being movable between a closed position and an opened position, in which latter position the film is exposed in use, and said plate (11) being arranged (a) to rest on and be supported by said shutter (13) when the latter is in its closed position and (b) to drop towards the photographic film when the shutter (13) is moved to its opened position.
Claim 3
Dependent Claim
50 words
Recording apparatus as claimed in claim 1 wherein the shutter (13) is arranged, when in said closed position, to hold the plate (11) clear of the film and, when in said opened position, to allow the plate (11) to drop so that its lower surface engages against the photographic film.
Claim 4
Dependent Claim
45 words
Recording apparatus as claimed in claim 1 or 2, wherein a member is provided between at least one of the vessels and the film, said member having portions of different optical transmission characteristics through which, in use, light from said vessel passes to the film.
Claim 5
Dependent Claim
18 words
Recording apparatus as claimed in Claim 3, wherein the member is in the form of a disc (100).
Claim 6
Dependent Claim
20 words
Recording apparatus as claimed in claim 4, wherein a plurality of discs (100) are provided as parts of a sheet.
Claim 7
Dependent Claim
22 words
Recording apparatus as claimed in Claim 4 or 5, wherein the discs (100) have transmission characteristics which vary circumferentially of the discs.
Claim 8
Dependent Claim
18 words
Recording apparatus as claimed in claim 6, wherein the portions of different transmission characteristics are of segmental form.
Claim 9
Dependent Claim
28 words
Recording apparatus as claimed in any one of claims 3 to 7, wherein the member having portions of different optical transmission characteristics is a graduated neutral density filter.
Claim 10
Dependent Claim
32 words
Recording apparatus as claimed in any preceding claim, further including means for correlating the individual images on this photographic film with the individual reactions which are conducted, in use in the vessels.
Claim 11
Dependent Claim
40 words
Recording apparatus as claimed in claim 9, wherein the correlating means comprises identification markings adjacent to some or all of the holes (15) in the plate (11), and an illumination arrangement for transferring the identification markings onto the photographic film.
Claim 12
Dependent Claim
28 words
Recording apparatus as claimed in claim 10, wherein the illumination arrangement includes a plurality of discrete light sources and means for controlling illumination of the discrete light sources.
Claim 13
Dependent Claim
16 words
Recording apparatus as claimed in claim 11, wherein the discrete light sources are light emitting diodes.
Claim 14
Dependent Claim
29 words
Recording apparatus as claimed in claim 10, 11 or 12, including one or more fixed intensity light sources for producing one or more reference images on the photographic film.
Claim 15
Dependent Claim
28 words
Recording apparatus as claimed in claim 9, wherein the correlating means comprises a separate overlay sheet which is laid over the photographic film when interpreting the images thereon.
Claim 16
Dependent Claim
20 words
Recording apparatus as claimed in Claim 1, wherein the cover (24) carries an array of supports (129) for a reagent.
Claim 17
Dependent Claim
38 words
Recording apparatus as claimed in Claim 15, wherein the cover (24) is arranged to carry the array of supports (129) for movement relative thereto towards and away from the plate (11) having the array of holes (15) therein.
Claim 18
Dependent Claim
96 words
Recording apparatus as claimed in any one of claims 1 to 13, wherein said cover (24 or 249) or carries an array of liquid dispensing tubes (28 or 228) which extend into said housing (20), each tube (28 or 228) having an opening at a lower end thereof whereby liquid can be dispensed therefrom in use into the reaction vessels, a common chamber (29 or 241) communicates with the interiors of the tubes (28, 228), and a sealable opening (32 or 240, 244 and 245) provides communication between the common chamber (29 or 241) and atmosphere.
