Title: Device for unloading radiographic cassettes
IPC: G03D13/00
Filed: 1974-07-05
Abstract: 1512009 Unloading radiographic cassettes AGFA-GEVAERT 3 June 1975 [5 July 1974] 29998/74 Heading G2X Apparatus for unlocking and hingeing open radiographic cassettes has means for guiding the cassette forward until its locked front end engages means which displaces levers forming part of the locking means, so unlocking the cassette. Figs. 1 and 3 show two different embodiments. In Fig. 1 a platform 12 is hinged to a platform 11 by a shaft 19, which can slide in slots 20 in platform 11. On the platform are two stops 13, 14 which are resiliently mounted so as to be spring-urged upwards. When the cassette 33 (shown in broken lines in Fig. 1) is placed in position on platform 11 its lower edge rests on the stops 13, 14, and their relatively strong loading springs (27) Fig. 2 (not shown), tend to correct the positioning if the cassette has been introduced slightly askew. Platform 12 is now pivoted up against platform 11, and pushed downwards, when brackets 17, 18 fixed on platform 12 engage the top edge of the cassette, and push it downwards, against the springs (27). The lower edge of the cassette is locked by a number of levers 21 (seen more clearly in the Fig. 3 embodiment). As the cassette moves downwards, a series of hook-shaped members 24 (also seen more clearly in Figs. 3 and 5) mounted on a fixed shaft 23 engage with bars 21, which are hooked open. In the Fig. 1 arrangement, in which platform 11 is inclined, the film sheets can then slide out of the cassette under their own weight, and if the device is suitably attached to a processing apparatus, the sheets can slide directly into it. In this case the unloading station is enclosed in a light-tight box 40. Provision may also be made for photographically printing additional data on to the film at this stage. In Fig. 3 the arrangement is horizontal, so that there is no need for platforms 12 and 11 to be hinged together. A pressure roller 34 holds the cassette firmly against platform 11. In this embodiment the cassette is pushed by hand in the direction of the arrow by pushing platform 12', and hence bracket 33, in this direction.

Title: Apparatus for Feeding Sliced Bread Loaves to Sliced Bread Loaf Packaging Apparatus
Inventor: PELKMAN JAN NIEULANT
IPC: B65B35/54
Filed: 1967-07-01
Abstract: 1,167,215. Endless conveyers. JOHN PELKMAN ENG. CO. Ltd. 30 Sept., 1968 [1 July, 1967], No. 30454/67. Heading B8A. Apparatus for feeding sliced loaves 22 from two slicing machines E (one only visible in Fig. 2), to a single packaging machine (not shown) comprises two input transportation means, A, B each adapted to transport loaves from one slicing machine to a common transfer region C, an output transportation means D adapted to transfer loaves from the transfer region C to the packaging machine, and means for insuring that two loaves are not fed simultaneously to the transfer region C from the two input means A, B. Loaves are fed along alternately between respective pairs of guides 25, 26 and 27, 28, to the transfer region C by flight bars 21 of an endless chain conveyer 13. Switches 51, 51 between the guides of each pair are in parallel with each other in a circuit controlling the packaging machine drive. Thus a loaf passing over and thus closing one of the switches 51, while the other switch remains open, has no effect on the apparatus. It two loaves are fed by the same flight bar 21 they arrive simultaneously over the two switches 51, 51 which are thereby opened together. This stops the packaging machine, and the conveyer 13 which is driven by this machine. Loaves are fed sequentially to the conveyer 13 from each slicing machine E by the action of an oscillating delivery arm 47 of the machine E, which co-operates with a stationary loaf-delivery plate 48. The arm 41 is actuated by a cam 44 on a shaft 46 which makes one revolution for each loaf fed to the machine E. The two cams 44 respective to the two machines E are 180 degrees out of phase. A gate member 33, 34 is pivotable by the passage of the loaves themselves or may be power driven in synchronism with the movement of the loaves. The guides 25-28 are supported from above at 61; other guides 35-38 are supported in a similar manner at 62. The guides are laterally adjustable to suit loaves of different size. Lower guides 65 of nylon are provided below the flight bars 21 and are supported by adjustment devices 32.

Abstract: 341,860. Gaseous-fuel furnaces; bakers' ovens. BAKER PERKINS, Ltd., Hythe Road, Willesden, London.-(Assignees of Engels, E. O.; Saginaw, Michigan, U.S.A.) Oct. 11, 1929, No. 30903. Convention date, Oct. 13, 1928. [Classes 51 (i) and 51 (ii).] In gas-fired bakers' and other ovens or chambers of the indirectly heated type, having within the oven chamber combustion flues or conduits enclosing the burners, the combustion products are exhausted from the heating-system by a jet of non- explosive diluent gas, such as air or steam, directed into the exhaust pipe or flue. By this means the accumulation of combustible gases in the system, and particularly in long exhaust flues, is prevented, and the risk of explosion is minimized. In the apparatus shown the combustion flues 2 are U- shaped, and are connected to feed and exhaust headers 4, 6 respectively. A combustible mixture is fed to the header 4 from a mixer supplied with air under pressure through a connection 5, and from this connection a pipe 9 delivers a jet of air into the exhaust flue 8 at a point close to the oven. The exhaust flue is reduced in diameter just beyond the air nozzle.
