Abstract: A sight testing apparatus for testing near sight comprises optotypes or other test figures and an optical distance measuring device for measuring the distance between the optotypes or figures and the position of a person under test and so constructed as to form an image at the position of the person under test. As shown in Fig.2 a three sided box 4, one side of which faces the person to be tested and carries optotypes, letters or the like, contains an optical system comprising a light source 90 which emits light which is reflected by mirrors 10 and 12 through lenses 13 and 14 on to the forehead 15 of the person under test. The mirror 10 is fixed and the mirror 12 is rotated by means of the worm gear mechanism 16 attached to the shaft 17 mounted in the tubular handle 6 so that the two reflected beams can be made to intersect on the forehead 15, the distance being measured by pointer 9 on shaft 17 cooperating with a fixed scale. In further embodiments a scale with large widths of the graduations is projected in such manner that the graduations whose numbering corresponds to the distance of a sharply defined image from the apparatus shows up sharply or a line from one beam is arranged to intersect the scale image.

Title: Electric discharge tube having at least one non-emitting electrode which consists at least superficially of nickel
IPC: H01J19/30
Filed: 1969-05-29
Abstract: In a method of manufacturing an electric discharge tube including a cathode and a non- emissive electrode having a nickel surface, the electrode surface facing the cathode is coated with a layer of gold and the tube is then evacuated and degassed at a temperature such that the electrode is heated to 600 to 800 C., preferably 780 C., so that the gold fully dissolves into the nickel without losing its emission-suppressive effect. Preferably the tube is degassed at 780 C. for 100 to 110 sees., and the electrode may form the anode of a high-voltage rectifier tube and comprise iron plated with nickel 16Á thick on which is initially provided a layer of gold less than 1Á thick. The gold-plating may be carried out in a drum by means of a bath which contains potassium-gold-cyanide and ammonia. If the electrode support, Fig. 1 (not shown), is of oxidized chromium-iron alloy it is found that it is not covered with gold by this process. The gold-plated electrode may also be, for example, a concentration plate in a beam pentode or an anode for an X-ray tube.

Title: Zinc extraction from zinc oxide and/or sulphide ores - by leaching and volatilising leach residue metals for max. recovery
IPC: C22B19/34
Filed: 1977-04-22
Abstract: Zn is extracted from Zn oxide ores and/or roasted ZnS concentrates by leaching and volatilising the leach residues. After neutral leaching, the leach residue contg. a large amt. of undissolved Zn, is dried and contacted in a fluidised state and in a reducing medium, with hot gases. Zn as well as other easily volatilised metal cpds. are evaporated and pptd. as their oxides. The non-volatilised cpds. are recovered as a slag and the mixt. of oxides is subjected to neutral leaching. Ores with high impurity contents may be treated to give high Zn recovery without requiring treatment of the residues to avoid pollution. Cyclone melting furnaces can be used with a consequent reduction in the space occupied.
Patent ES-466083-A1 (ES)
Title: Thread storage and delivery apparatus
IPC: B65H51/22
Filed: 1978-01-17
Abstract: A rotatable shaft carries a winding instrumentality whereby thread to be temporarily stored is coiled around a thread drum rotatably mounted on the shaft. Rotation of the thread drum in the direction of shaft rotation is prevented by concentric relatively fixed and movable brake elements, the fixed one secured to housing for the apparatus, the movable one coaxially secured to the thread drum. One of the brake elements has a circumferential surface from which elongated resilient fingers project, the fingers being more or less radial to said surface and having their tips normally engaged under flexing bias against a circumferential braking surface on the other brake element. The thread passes through the zone of the fingers, and the several fingers are so inclined to radials from the common center of the brake elements that the thread, or a guide tube through which it extends, can flexingly cam each finger, in turn, out of engagement with the braking surface and pass around the finger.

Patent ES-8105964-A1 (ES)
Title: Waste treatment apparatus
IPC: C02F3/12
Filed: 1980-07-24
Abstract: A waste treatment apparatus provides a cylindrical vessel adapted to receive a waste water flow therethrough to be treated. The vessel provides an aeration chamber at the outer peripheral portion thereof, with a desirable generally helical flow being generated by aeration bubbles striking angularly deposed baffle plates. A clarifier is provided at the central portion of the cylindrical vessel for clarifying a liquid which enters the clarifier from the aeration chamber. The clarifier comprises a first settling chamber and a second decant chamber through which clear water is collected and transmitted to a chlorination chamber for subsequent discharge. The angularly deposed baffle plates are mounted in the upper portion of the aeration chamber and aid in spinning waste water in a circular or curved path. Likewise, a pair of aeration diffusers mounted in the lower portion of the aeration chamber near the center of the cylindrical vessel move waste water to be treated upwardly and outwardly in a circular path. The combination of the diffusers and the baffles move the waste water in a generally helical path for prolonged contact time and improved mechanical masceration. Additionally, the helical path thus generated tends to move solids away from the clarifier entrance thus further enhancing the separation of solids from the decant liquor.
