Title: Variable infusion control device
IPC: F16K3/08
Filed: 1974-04-24
Abstract: 1471955 Fluid regulation SORENSON RESEARCH CO Inc 24 April 1974 [30 April 1973] 17900/74 Heading G3H In a variable infusion control device for controlling the flow of a parenteral liquid into a patient, a rotatable control member 44 is positioned between an inlet member 80 having an inlet orifice 94 and an outlet member 12 having an outlet orifice 23. The control member is formed with a part circular capillary groove 60 on opposite faces of an internal radial flange 50, each groove ending at a through port 64. The grooves are covered by non-rotatable seals 32, 70 each having a through bore 38, 72 aligned with orifices 94, 23. If port 64 is positioned in alignment with bores 38, 72 and orifices 94, 23 full flow takes place. If surface 66 of flange 50 is positioned opposite bores 38, 22 no flow takes place and if a portion of the grooves 60 communicate with the bores 38, 72 a throttled flow occurs, the flow-rate depending on the lengths of grooves 60 between the port 64 and the bores 38, 72. In a modification a series of different sized capillary grooves each ending in a through port are formed in each face of the flange 50. In a further modification each capillary groove 60 has a series of spaced different sized restrictions therealong. The members 12, 44 can have co-operating stops (145), (147) or a series of peripheral notches (247) can be formed on the member 12 and co-operate with a resilient finger (245) to lock the member 44 in position.

Abstract: 811,518. Dispenser for drinking straws. PORTA SORBEDORES YGIENIC S.A. June 11, 1956 [March 9, 1956], No. 17997/56. Class 18. A straw dispenser comprises a chamber 1 in which the straws are held substantially vertical, the chamber floor 15 being conical so that straws move down towards a rotary agitator 17 having a bore 19 through which an element 26 rises to push the central straw above the others to enable it to be readily grasped. The element 26 is carried on a flexible strip 24 moved in a channel 23 by a lever 27, 28. The strip 24 has a twisted portion 34 passing through a slot in a member 21 secured to the agitator so that as the strip is pushed upwards by movement of the lever, the portion 34 causes rotation of the agitator. The agitator has fins 18, Fig. 3 (not shown), on its upper conical surface which stir the straws, and has a pin 35 attached to a spring 36, the latter damping the movement of the agitator and assisting its return to its initial position. The member 26 is returned by return movement of the lever under the influence of a spring 31. As a straw is raised, it pushes apart flexible lips 41 in the top 38 of the chamber 1, this member being of plastic. The lips retain the straw in the raised position.

The stopper 28 preferably includes a frusto-conical surface 29 seating against a complementary surface on the member 15. The member 15 is screw-threadedly secured to a split ring 13 engaging the bottle neck below a rib 11 thereon. The closure member 22 is screw-threadedly secured to a projection 20 on the member 15 and also carries a screw-threaded projection 24 for engagement with a second screw cap 26. In use, the stopper 28 is pushed into the bottle neck away from its frusto-conical seat, and the bottle is inverted so that sediment collects in the closure member 22, leakage via the aperture 23 being negligible. The stopper 28 is then pulled into engagement with the seat on the member 15, preferably with a snap-fit action, by means of the rod 30. The rod 30 may be rigid and removable so that the closure member 22 can then be removed to dispose of the sediment. Alternatively, the rod 30 can be flexible, so that it passes through the aperture 23 for removal of the closure member 22. The closure member 22 may then be replaced or the cap 26 may be secured to the annular member with the flexible rod 30 coiled inside. The stopper 28 is preferably of elastomeric material and the annular member, closure member and cap of moulded plastics material.

Title: Improvements in semiconductor injection recombination radiation sources
IPC: H05B33/14
Filed: 1965-04-29
Abstract: A semi-conductor injection recombination radiation source consists of a layered structure comprising a support, a first electrode, a semi-conductive layer of a P-type chalcogenide grown from the vapour phase, an N-type semi-conductive layer, and a second electrode.  A chalcogenide is defined as an oxide, sulphide, selenide. <PICT:1057992/C4-C5/1> or telluride of a metal.  As shown, a layer 2 of iridium is sputtered on to a glass plate 1 and covered with a thin layer of silver by vapour deposition.  A layer 4 of zinc selenide is vapour deposited in vacuo on to layer 2 and is then heated in an atmosphere of argon to diffuse the silver into layer 4 to make it P-conductive.  A transparent electrode 6 of indium oxide is applied to layer 4 and the device is heated to diffuse indium from electrode 6 into layer 4 to form N-type region 5.  The device is mounted in a transparent envelope and when forward biased emits radiation through electrode 6. Electrode 2 may also be of transparent material or alternatively electrode 2 and substrate 1 may form a reflective surface.  Layer 4 may also be doped by the vapour deposition of an acceptor simultaneously with the deposition of the semi-conductor material.  Layer 4 may be produced by the reaction of vapours of hydrogen selenide and zinc chloride at the surface of the substrate. Cadmium telluride is also mentioned as a suitable semi-conductor material.  A plurality of devices may be produced on a single support and may be combined with photo-sensitive layers to produce opto-electronic devices.

In other embodiments, the abrasive particles are in layers or intermixed in the epoxy resin, and the globules may be formed on enlarged ends on the bristles. The uncoated parts of the bristles permits the bristles to flex so that the brush can be used on holes of different diameters.

Title: Improvements in apparatus for the objective measurement of the refractive value of the principal point of the eye
IPC: A61B3/103
Filed: 1920-07-05
Abstract: 148,754. Zeiss, C., [Firm of]. July 23, 1919, [Convention date]. Sight-testing apparatus.-The refractive error of the eye is measured by an instrument based on the principle that when a lens c is placed in front of the eye, with relaxed accommodation, so that the distance between the adjacent principal points of the eye and lens is equal to the focal length of the lens, the error of the eye in diopters is proportional to the distance of the conjugate point of the retina, with respect to both eye and lens from the second focal plane of the lens c. The image of the retina formed by the lens c is examined by means of a lens g, the emergent parallel rays being then observed by a telescope consisting of an objective m<1> and eye-piece p. A " Scheiner " disk h with two small holes h<1>, h<2> is rigidly fixed in the focal plane of the lens g. The retina is illuminated by a glow lamp r, an image of which is formed by lenses s<1>, s<2> and the prism t on the diaphragm h adjacent to the holes h<1>, h<2>. The lenses g, c form images of the lamps r and the holes h<1>, h<2> in the pupil of the eye, so that the retina is illuminated by diffused light and a virtual aperture consisting of two small holes is formed in the pupil of the eye. Two separate small pencils of light from the retina then pass through the instrument to prisms k<1>, k<2> and prisms l<1>, l<2> respectively, from which they pass through objectives m<1>, m<2> and prisms n<1>, n<2>, o<1>, o<2> to a common eye-piece p. The face o<3> of the prism o<2> is partially silvered so that the observer's eye sees two partial images. The lens g is moved until coincidence of the partial images is obtained, and the error of the eye in diopters is read off on a uniform scale d' by means of a pointer a<2>. By rotating the diaphragm h and the illuminating tube the error in any meridian may be determined, the meridian being indicated by a scale d<2>. Alternatively, these parts mav be fixed and a reflecting prism rotated through half the angle to the vertical of the meridian it is desired to examine. A mark s<3> on the lens o<1> is focussed on the retina to ensure relaxed accommodation.
