Patent GB-1390678-A (GB)
Title: Dispensing measured volumes of liquid
IPC: B01L99/00
Filed: 1972-03-20
Abstract: 1390678 Dispensing measured volumes of liquid for testing AGA AB 20 March 1972 [26 March 1971] 12910/72 Heading B8N A measured volume of liquid is obtained for testing by causing liquid to flow from a reservoir via a tube, e.g. a capillary tube, to the level 1, the flow being caused by the application of pressurized gas at 11 or suction at 16. During the flow a valve 7 maintains the orifice 1 closed. Upon the leading liquid/gas interface reaching the level 1, a detector 14, 15 causes mechanism 8 to move the valve 7 away from the orifice to allow gas at a pressure greater than or equal to that at 11 to enter the tube. The volume of liquid between the orifice 4 and the level 1 is thus dispensed, and the liquid in tube portion 3 will return to the reservoir. The process may be repeated automatically, in which case the mechanism 8 automatically causes the valve 7 to move to close the orifice, e.g. when the rear meniscus of the liquid volume passes a particular level in the tube portion 2 and actuates a detection device (not shown). In the modified apparatus of Fig. 2, a suitable pressure differential between liquid surface in the container 9 and outlet 16 will, when aperture 4 is closed, cause liquid to flow into container 21 as well as along the tube. When level 17 is reached a detector device will cause aperture 19 to be closed, and liquid will continue to flow along the tube 20 until level 18, or level 1 is reached, at which point a detector device will cause termination of gas supply to container 9 and apertures 4 and 19 to open to allow introduction of pressure gas into the tube to force that volume of liquid between aperture 4 and level 18 or level 1 and in container 21 through outlet 16.  The detection device 14, 15 may be movable to enable variation of the volume dispensed, or a selected one of a plurality of stationary detection devices may be used for the same purpose. An additional detection device between the aperture 4 and level 1 may be used to detect the number of liquid 1 gas interfaces and to activate an alarm if more than two interfaces are sensed during each dispensing operation. Alternatively the additional detection device may be placed between the level 1 and the outlet end 16, and at a distance from the level 1 corresponding to the distance between level 1 and aperture 4. Thus if a gas bubble is present in the volumes to be dispensed the front and rear menisci will not be detected simultaneously and an alarm will be given.

Abstract: 561,058. Delivery apparatus. GOSS PRINTING PRESS CO., Ltd., and WHITEHEAD, W. A. Sept. 28, 1942, No. 13606. [Class 100 (i)] A device for delivering sheets in counted batches comprises an S-fly 10, which normally delivers the copies x with their folded edges undermost on a conveyer band 12, is constructed with one or two flipper arms 20 having pockets 21 for receiving the last sheet y of a quire and causing it to be displaced relatively to the remaining sheets. The arms 20 are mounted so as to be oscillated about a pivot 24 by'means of a cam 28 which raises the pockets 21 from the position shown in Fig. 2 to a position in which the pockets can strip a sheet from the blades 11 of the S-fly. The arms 20 then drop to the position shown in Fig. 2 and displace the sheet y, and the arms are then withdrawn laterally out of contact with the sheet y by means of face cams 29 which cause pivotal movement about pivots 22 in order to withdraw the pockets laterally out of the plane of the sheets. Slotted sheet guides 40 prevent the counted sheet from following the pockets. After withdrawal of the pockets, the arms 20 are first raised and then moved laterally inwards at the correct time to engage the next counted sheet. The lower jaws of the pockets 21 are shorter than the upper ones so as to facilitate withdrawal of the pockets, and the construction set forth permits of reduced sensitivity of timing and setting of the movement of the flippers since they do not have to avoid contact with other copies leaving the fly.
