Abstract: 1435374 Discharging liquids by gaseous pressure MICROMEDIC SYSTEMS Inc 25 April 1973 [1 May 1972] 19565/73 Heading F1R [Also in Division G1] Liquid is transferred from a vessel 18 through a dip tube 22 by applying air-pressure to the vessel through an opening 82 so that the flow of air passes over the dip tube to clean it. Air is supplied to a chamber 78 in a head 54 and through which the tube 22 passes and flows to the opening 82 and also to an opening 74. The vessel 18 is mounted on a guide which is raised to cause the mouth of the vessel to seat on a seal 62 in the head 54. Further raising causes the mouth of the opening 74 to engage a seal 72 on a plate 70 and the dip tube to enter the vessel. The quantity of liquid discharged may be controlled by a solenoid actuated valve (26) Fig. 6 (not shown) controlled by a timing device (108) started when a rise in pressure in the vessel due to closing of the opening 74 is detected. In a modification, Fig. 5, a crank mechanism 146 operates a slide 142 round which the dip tube 152 is looped so that the tube is inserted into the vessel 120 in a separate operation. As described the apparatus comprises pairs of vessels and duplicate discharge arrangements.

Abstract: 1277762 Blood sampling apparatus MICROMEDIC SYSTEMS Inc 16 July 1969 [26 July 1968] 35716/69 Heading A5R Apparatus is provided for obtaining a blood sample from a patient's finger using a collector device 15, Fig. 11, of the type disclosed in Specification 1277761 having a tube 32 and a resilient funnel member 35 with incisor lancets 38a, 38b, the apparatus having a mounting 12, Fig. 2, having a through passage 12c in which the collector 15 is supported, a striker mechanism having a releasable member 17 adapted to strike a lower end of tube 32 to force lancets 38a, b into a patients' finger placed over funnel 35, a finger holder 8, and means for periodically varying the intensity of clamping of said holder. Holder 8 is pivoted at 7 and has a pin 8c which during pivoting of the holder engages member 17, to pivot the latter against springs 14, and then releases member 17 which consequently strikes tube 32. Holder 8 is retained in its clamping position by engagement of teeth 8f with a grooved rod 29 on a lever 25, the degree of clamping being varied by a massaging-type movement of a finger support 6 on a lever 19 driven through an eccentric by a motor. The first drops of impure blood are absorbed by a pad 40 in funnel 35, the remaining sample passing into tube 32 until a light beam, passing through tube 32 from a source to a photo cell in mounting 12, is interrupted, whereupon a solenoid coil 23 is energised and attracts an armature 22 on a lever 21, the end of which lever thus becomes engageable with a projection 19a on lever 19 to move levers 21 and 25 thus releasing holder 8 which is acted on by a return spring 11, the actuation of the solenoid also stopping the motor. Holder 8 may alternatively be released and the motor stopped via a push button 4. In an alternative embodiment, Figs. 13-16 (not shown) the finger is clamped and massaged between a fixed swell (45) on a casing (42) and a sponge pad (46) secured to a stirrup (41) pivoted on an eccentrically driven pin (43).

Abstract: 1281353 Reciprocating pumps MICROMEDIC SYSTEMS Inc 15 Aug 1969 [16 Aug 1968] 40900/69 Heading F1A A pump, e. g. for metering liquids in laboratories, comprises a piston 3 reciprocable in a cylinder 1 in synchronism with a rotary face valve 6 driven by a wheel 72, the cylinder 1, valve 6 and a coupling member 30 being mounted in a casing 37, 38 which is removably mounted by bayonet pins 50, 51 in bayonet slots 53, 54 in a ring 55 pivoted in a frame 59, a releasable locking pin, Fig. 4 (not shown), preventing rotation of the casing in the ring. A spring 34 biases valve member 6 against valve seat 5 to provide sealing when the casing is detached from the frame, additional spring-loading during operation being provided by spring 63 acting through ball 60 and coupling member 30. Valve 6 may be of P. T. F. E. and has grooves 25, 26 for alternately connecting cylinder port 12 to inlet and outlet ports 20 in seat 5, Figs. 2 and 3 (not shown). The grooves 25, 26 may be arranged in the form of a cross, or may be arcuate. Coupling member 30 has sawtooth projections, Figs. 4 and 5 (not shown), for engaging drive pins 70, 71 of wheel 72. The locking pin passes through one of the trunnions supporting ring 55 and is spring-loaded into an axial slot in casing 38, a bevel 69 depressing the pin for entry of the casing into the ring.

Abstract: Apparatus for repeatedly metering and dispensing, by means of a piston pump, predetermined quantities of liquid via a switching valve to which are connected inlet and outlet conduits for the liquid. The pump and the valve are actuated in timed relation by a drive mechanism powered by an electric motor which is controlled by selectively operable means that automatically cut off the motor supply once the piston has completed a stroke. There are also provided means for varying the length of the piston stroke to adjust the volume of said quantities and means for displaying to the outside a number indicative of this volume.

Abstract: 1282004 Linkwork; bearings MICROMEDIC SYSTEMS Inc 15 Aug 1969 [16 Aug 1968] 40899/69 Headings F2A and F2K Rotation of an input shaft 3 is converted into reciprocating movement, of variable amplitude, of an output member 43 by a mechanism comprising a crank-pin in the form of a rod 14 which is driven in such a way as to describe a core having an axis 26, Fig. 2, a runner 27 within which the rod 14 can slide, screw-and-nut mechanism 46, 47 for adjusting the longitudinal position of the rod 14 relative to the runner 27, and a yoke member 42 connected to output member 43 and to a rod 31 which guides the runner 27 and is constrained to move in a direction 39 perpendicular to the core axis 26. The rod 14 is secured at one end to a plate 15 which carries slide blocks 10, 11 which are disposed in grooves 8, 9 in a cup-shaped member 5 secured to the input shaft 3. The other end of rod 14 carries an eccentric lug 17 on which is secured a ball 18 retained by a plate 21 in a socket 19 formed in a slide member 20. Rotation of a knob 65 causes rotation of a sleeve 48 carrying the nut 47 and axial movement of slide 20, thereby causing axial movement of rod 14 to vary the amplitude of reciprocation of the output member 43. In the position shown, the rod 14 is parallel to the axis of cup-member 5, and it may be located in that position by a ball 70. Thus the upper limit of reciprocation remains fixed. The sleeve 48 is rotatably mounted with respect to a support 60 by a resilient bearing formed by a triangular frame comprising resilient rods 51, 52 and 53. The ends of the rods are held in the support 60 whilst their middle points co-operate with a circular groove 64 in the sleeve 48.
