Title: Selective chemical sensitive devices
IPC: H01L29/78
Filed: 1976-03-11
Abstract: 1529743 Chemical sensitive field effect transistor UNIVERSITY OF UTAH 11 March 1976 [12 March 1975] 09752/76 Heading G1N [Also in Division H1] A chemical sensitive field effect transistor com prises a semi-conductor substrate 30, two diffusion regions 32, 34 of opposite doping polarity, electrical insulation 36 covering at least part of the diffusion regions and the substrate between the doped regions and a chemical selective system 38 overlying the insulator 36 between the doped regions. The chemical selective system reacts with certain substances to modulate an electric field produced between the diffusion regions 32, 34 which comprise the transistor source and drain. Preferably all of the device, except the chemical selective system 38 is covered by an insulating layer 44. The chemical selective system may be ion selective, selective to particular gases or selective to particular enzymes or substrates. As shown in Fig. 1, the system 38 may comprise a membrane of PVC, polyurethane or silicone rubber, impregnated with an ion exchanger e.g. calcium didodecylphosphate for calcium specificity. The membrane may also comprise a solid state or crystal ionic conductive membrane. A third alternative comprises a hydrophobic polymer membrane of which is swelled by the action of a hydrocarbon derivative with protein reactive groups. Antibodies, antigens enzymes and substrates can be fixed to the reactive groups to form the selective device. The polymers may be PVC, polyurethane, polycarbonate, PTFE, epoxy resin or cross-linked polyester and typical hydrocarbon derivatives are n-deconol, n-hexanol, n-decylamine, n-hexylamine. The Figure 2 transducer functions by the setting up of a potential related to solution concentration relative to reference electrode 48, this potential affecting the source-drain current of the FET. A second embodiment (Fig. 3) comprises a layer of insulation 66 arranged over substrate 60 and diffusion regions 62, 64. Two electrodes 68, 70 of noble metal separated by a rare earth fluoride are fixed to insulator 66 as shown and the outer electrode is covered by a selective gas permeable membrane 74. Gas diffusing through membrane 74 alters the current supplied between electrodes 68, 70 and the transistor source-drain current. In a modification, membrane 74 may be replaced by a membrane containing immobilized enzyme or substrate (e.g. glucose or lactose oxidase in agar) or the constant current source and membrane may be replaced by an ion selective membrane overlaid with an immobilized enzyme or substrate containing membrane. The transistor may be situated in a needle tip for insertion into a patient or in one half of a dual lumen catheter. It may also be mounted against a hole in the wall of a tube, through which a test fluid flows. A plurality of transistors, responsive to different materials may be integrated on to a single substrate. The transistor gain gives the device a good signal to noise ratio.

Title: Apparatus for metering and distributing fluid
IPC: G01F15/07
Filed: 1958-03-26
Abstract: 857,796. Dispensing liquids. SOC. D'ETUDES D'INVENTIONS ET DE BREVETS S.E.I.B. March 26, 1958 [March 26, 1957], No. 9755/58. Class 116 [Also in Group XXIX] Liquid metering apparatus comprises a pump and flow meter and one or more stops arranged in the path of a meter-driven element at a point corresponding to the quantity to be delivered, or the price of the quantity, and the contact of the element and stop automatically causes the closing of the delivery valve of the apparatus. The stops comprise press-studs 27 bevelled and notched at one end so that when one stud is pressed in to engage a hole 33a in a spring- loaded plate 33, the plate is depressed to release a previously-depressed stud and then returned to lock the stud being pressed. A shaft 11 driven by the fractional delivery indicator carries a cam 12 and a sleeve 14 journalled on the shaft 11 carries a cam 15 and has a pinion 24 which is driven by the totalizing mechanism and is rotatable on the sleeve but can be coupled to it by a coil spring 26 connected to a ratchet wheel 25. A rack 19 provided with a latch 29 is engaged with a pinion 18 connected to a shutter 20 which has a nose 20a masking a notch 15a in the cam 15, the shutter normally rotating with the cam as it is held against a stop 15c Ly a spring 22. During delivery, the delivery valve 28 is held open by a lever 31 bearing on the cam 15 and the motor drives the shaft 11 and cam 12 and, through the spring clutch 26, the sleeve 14 and cam 15. Slightly before the full quantity has been delivered, the latch 29 engages the selected pressstud, thus arresting the rack 19 and the shutter 20. The cam 15 continues to rotate, tensioning the spring 22, and the notch 15a is uncovered so that the end of the lever 31 can fall into it and allow the valve 28 to close partially. Delivery at a reduced speed continues through a by-pass 28b until the end of the lever 31 can fall into a notch 12a in the cam 12 and allow the valve 28 to close completely. When the operator hooks up the delivery nozzle, the pump is stopped and a spring 37 opens the valve 28 against the diminishing pressure of the liquid and withdraws the end of the lever 31 from the notches. The operator zeroises the apparatus by rotating the shaft 11 and this causes a pawl to turn the ratchet wheel 25 so that the grip of the spring clutch 26 is released and the cam 15 and rack 19 can be spring-returned to their initial positions.
