Title: Aparato para desinfectar lentes de contacto, que tienen un elemento de ventilacion mejorado
Inventor: ALVORD LARRY ALLEN
IPC: G02B5/00
Filed: 1996-05-31
Abstract: Un aparato para desinfectar lentes oftálmicos, el cual incluye un recipiente y una tapa de acoplamiento, teniendo el aparato un elemento de sello y ventilación mejorado para ventilar el gas generado dentro del aparato. El elemento de ventilación es una parte integral del aparato de desinfección, que permite ventilar el gas cuando se incrementa la presión interna, mientras que se mantiene un sello que es sustancialmente impermeable al gas y al líquido en los otros tiempos. El sello se define por el acoplamiento de interferencia de una periferia felxible de un recipiente con un borde de acoplamiento rigido de una tapa. El aparato es particularmente útil para la desinfección de lentes de contacto con perócido de hidrógeno, en donde el exceso de peróxido se descompone en agua y oxígeno.

Abstract: 857,602. Fused-electrolyte cells. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 4, 1957 [June 7, 1956], No. 17749/57. Class 41 An electrolytic cell 1 for producing high purity metals and alloys by electrolysing a molten salt comprises a muffle 5 having at least the inner walls of metal, a crucible 11 of an electrically conductive refractory material, e.g. graphite, removably disposed in the muffle 5 and forming one electrode, a further electrode 25, and means 14, 12 electrically insulated from the muffle 5 for leading current to the crucible 11. The cell 1 communicates through slide valves 3, 4 with a cooling chamber 2. The crucible 11 is connected as anode through a conducting plate 12 and a wire 14, the plate 12 resting on insulation 13 in the muffle 5 which is heated by an electric heating element 7. A cathode 25 depends from packing 26 in the chamber 2 which has a cooling water jacket 23. Each valve 3, 4 comprises two members 34, 35 forming a casing in which is slidable a rod 36 carrying a plate 37 and a cover 38 which may be raised or lowered by rotating the rod 36 to actuate a cam 40 on the rod 36. There are joint packings between the members 34, 35, 38, e.g. at 33, 39. The cell is operated as follows:-With the chamber 2 removed, air is withdrawn from the muffle 5 by a pump attached to a valve 21, the muffle being heated. Next, inert gas is admitted at 17 into the muffle to restore the pressure, and the electrolyte salts put in the crucible 11. The salts, if desired after being degassed, are heated in an inert atmosphere or in a vacuum, and when molten, inert gas is introduced at 17, and leaves at 21. The chamber 2 is then fitted to the cell by screwing the valve 3 to the valve 4, degassed if desired, and the valves 3, 4 opened, the inert gas leaving at 24, and the cathode 25 lowered. When electrolysis is completed, the cathode 25 is raised, the valve 3 closed, and the cathode left to cool in the chamber 2. In a modification, electrical contact to the plate 12 is by a rod in the conduit beneath the plate 12 which leads to the exterior of the cell. Specification 851,444 is referred to.

Abstract: 1,233,822. 822. Current and magnetic field measurement. COMPAGNIE GENERALE D'ELECTRICITE. Feb.26, 1969 [Feb.27, 1968; Oct.3, 1968; Dec.3, 1968], No.10248/69. Headings GIA, G1N and G1U. In an electric current transforming arrangement a magnetostrictive rod is placed in the field of the current to be transformed or measured and has a mirror (grating or diffuser) mounted thereon whereby light from a source falling on a detector is modulated by changes in the current. The line conductor may be looped into one or more turns and the rod may be polarized by a coil or a permanent magnet, the former of which may be energized by A. C. for the apparatus to serve as a D.C. transformer. Two identical rods one of which is screened from the magnetic field may be used for temperature compensation and the rods which may be cylindrical may be interconnected by a good heat conductor. In a null arrangement Fig. light from a source 2 which may be a sodium vapour lamp or a laser is split by a mirror 3 and supplied to a pair of interferometers 4, 5 the former having a mirror carried by a rod responsive to the current to be transformed and the latter having a similar rod responsive to a field proportional to the error current developed by a comparison in unit 6 of the two interferometer outputs. The current affecting the rod in interferometer 4 may be indicated by ammeter 8. The use of Michelson, Twyman Green, Fabry- Perot and Jamin interferometers is referred to and in a null system described with reference to Fig.4 (not shown) the output light from one current responsive interferometer arrangement is applied to a succeeding differential pair having a common nulling coil around a magnetostrictive rod. Embodiments in which the rod is a tube surrounding the conductor and is supported at one of its ends or at its centre are also described, the tube carrying at its free end or ends a concave mirror and deforming torsionally with changes of current. Further arrangements in which the movable mirror is rotated relative to the fixed mirror or in which the two mirrors are rotated and the light source is a particular wavelength or group of wavelengths have light guides and a vibrating slot aperture whereby pulses corresponding to the number of fringes may be counted. In a further null method Fig.10 in which mirror 142 is mounted on the magnetostrictive rod, the light from mirror 142 is split by a separator 143 and the compensating wedge 147 is adjusted to maintain equality of pulses directed alternately by a mixer 150 on to a photo-cell 152. A further embodiment uses variations in the reflection of diffused light and two still further embodiments are directed to the automatic control of the output power of a laser by a permanent magnet biased rod carrying a mirror in the beam path in which the current derived by a photo-cell from the beam is passed through the rod itself.

Abstract: 1,238,649. Resuscitation apparatus. P. H. VENN and A. MARTIN. 19 May, 1969 [21 Feb., 1968], No. 38511/67. Heading AST. A resuscitation apparatus comprises a squeezable bag (10, Fig. 1, not shown) a face mask and a non-rebreathing valve comprising a tube 22 connecting mask and bag, slidable within which is a carrier 24 on which is mounted a non-return valve 30 permitting air to flow from bag to mask, the carrier being movable by the difference of pressure in bag and mask between a first position where air can enter the bag from ambient atmosphere through inlet ports 26 in the tube 22 and exhaled air can pass from the mask through outlet ports 27 in the tube, and a second position in which the inlet and outlet ports are closed by the carrier, the carrier being located so that the non-return valve is between the inlet and outlet ports when the carrier is in the first position.  As described, carrier 24 is slidable between stop screw 23 and a shoulder 35. The carrier carries a one way valve 30 having a disc 31, stem 32 and spring 33. An inlet 12 with a non-return valve 13 may be used to add oxygen to the breathing air in the bag. When the bag (10) is compressed air pressure drives the carrier to shoulder 35 and valve 30 opens, as appears in Fig. 2. When the bag is released, valve 30 closes and the carrier is drawn back to stop 23 (as in Fig. 1) in which position ports 25 are aligned with ports 26 to admit fresh air to the bag and ports 27 are opened to permit exhaled air to escape from the mask. Alternatively a flap valve (38, Fig. 3 and 55, Fig. 4, not shown) can replace the spring loaded valve 30, or the carrier may have the shape of a spool (53, Fig. 4) with extended flanges (52, 54) to close the air inlet (51) and mask exhaust (43) ports.
