Title: Apparatus for dispensing parenteral fluid
IPC: A61M5/148
Filed: 1967-06-24
Abstract: Apparatus used for transfusion comprises a gas-tight rigid casing 21, 22, compressible reservoir 23, 30 adapted to contain the substance to be transfused and mounted in the casing, an outlet 32 for connecting the reservoir to a catheter, a valve in the casing for introducing pressurized gas into the casing, so as to compress the reservoir and eject its contents, and an adjustable valve member 33 for regulating the outlet flow from the reservoir, there being a wire or thread 50 passing through and maintained in the opening of the valve member and extending into the interior of the reservoir for preventing adhesion of the walls of the reservoir at least in the proximity of the wire or thread. As shown, the casing is of a transparent material 22 within a' metal envelope 21 and flexible containers 23, 30 form the reservoir and contain physiological liquid and plasma respectively, the liquid and plasma being mixed and ejected through the outlet tube 32 from the apparatus by compressed air 26 introduced into the casing through a valve (not shown). The containers are initially separated by a membrane 31 which is ruptured by air pressure acting on the containers when an outlet valve 33 is first opened. A wire 50 may be arranged to extend into the containers to prevent the walls of the containers closing together completely and so preventing the plasma solution being ejected and this wire may be manipulated to cause the rupture of the membrane. The valve 33 (see also Figure 2, not shown) which controls the rate of ejection of the solution, comprises pincer jaws (39) arranged to clamp the ejection tube 32, the valve also including a pointer (38) which indicates the amount of transfusion time in hand. The metal envelope 21 may have a slit through which the containers can be observed. The reservoir may be of an elastic and transparent material.

Patent ES-369228-A1 (ES)
Title: Mark read apparatus using small raster
IPC: G06K7/10
Filed: 1969-07-07
Abstract: Each mark area 25 is scanned by a light spot in a plurality of parallel lines to produce a sense signal each time the spot crosses a mark, and the sense signals are examined to determine whether the scanned mark is valid. Scanning operation.-An external source, e.g. a computer, supplies terminals 56, 58 with signals representing the co-ordinates of a starting point A and sets latch 66 so that controls 54, 48 position the beam of CRT 46 at point A, H and V beam position signals being fed back to control 54. Latch 66 is then reset and logic 78 starts a fast scan downwards. When a timing mark 22 is detected by photomultiplier 43, the V beam position signal is stored at 80, and a predetermined distance later in the vertical sweep (position B) the V beam position signal is stored at 82, the reset signal to counter 96 is removed and a small raster scan is started. The first up-sweep scan in which timing mark 22 is not crossed is detected at 84 and an H beam position signal corresponding to the centre of mark 22 is stored at 86. Logic 90 causes a fast left sweep to be superimposed on part of the next up sweep CD (VSR1-VSR20) to cause a jump to the first mark position. Scanning of the first mark position continues for 20 up sweeps (counter 102) when a jump EF is made (VSR1-VSR30), the gap between mark positions being greater than that between timing mark 22 and the first mark position. Scanning continues in this manner until the end of the last mark position G when counters 100, 102 set latch 66 to cause the CRT beam to be retraced to position H (actually the same as B) under control of the signals stored at 82, 86. Detection of the next timing mark and scanning of the next row take place in a similar manner. Mark signal processing.-Timing circuit 76 rejects narrow pulses from thin marks. Logic 88 provides a gating period for mark sense signals during part of each up sweep, VSR16- VSR30 for timing marks 22 and VSR8-VSR30 data mark positions, the timing marks being displaced vertically from the rows of mark positions. Logic 92 receives the mark positionidentifying signals DA1-DA12 and provides a signal on a corresponding output provided a minimum number of mark sense signals are detected during the scanning of a mark position. Logic 94 provides an output if a small number of mark sense signals are obtained during scanning of a mark position e.g. for a partially erased mark and gives an indication (not necessarily unambiguous) of which position is involved.
