Title: Molecular sieve desorption with a mixture of hydrocarbons
IPC: C07C1/00
Filed: 1969-10-30
Abstract: Gaseous straight chain hydrocarbons are separated from a petroleum fraction, e.g. C 10 -C 20 , using a molecular sieve, e.g. Type 5A. e.g. sodium calcium aluminosilicate, in a cyclic vapour phase process which includes the steps of adsorption, purging and desorption, the latter two steps being carried out using the same medium, viz one comprising a straight chain hydrocarbon mixture composed of a major amount of at least one straight chain hydrocarbon having 5 to 7 carbon atoms less than the lightest straight chain hydrocarbon of the petroleum fraction, and a minor amount of a straight chain hydrocarbon having 1 to 3 carbon atoms less than the lightest straight chain hydrocarbon. Examples of the medium given are n-heptane and n-undecane. As shown a mixture of straight and non- straight hydrocarbons is fed from pipe 10 to adsorption tower 14 mounted at elevated temperature and pressure. The straight chain components are selectively adsorbed while effluent exits via pipe 16 to a fractionater 18. The non-straight hydrocarbons exit via line 21 whereas any desorbing medium (from a previous desorption step) is recycled via line 19. At the purge stage 14A the tower is depressurised and the adsorbent is purged countercurrently with desorbing medium added from lines 40, 42, 44. Purge effluent is collected in purge accumulator 54 before being recycled. At the desorption stage 14B the tower is repressurised above that used in the adsorption step and desorbing medium added via line 43. The effluent is separated by fractionator 60 into desorbing material which is recycled via line 62, and straight chain hydrocarbons which are collected via line 64. Three towers may be used or each stage may have more than one tower in parallel.

Title: Security systems
IPC: G07C9/27
Filed: 1972-11-07
Abstract: A security system controls admission of persons to protected areas. An authorised person carries in his pocket a token which generates at two discrete frequencies and when he approaches a door leading to the restricted area, a sensor of his presence sends an initiating signal to a control unit which examines whether the required discrete frequencies are being generated and are being picked up by inductive loops adjacent the door. If the correct signals are being generated the door is automatically opened but if not the door remains closed and an alarm may be given. The user does not need to take his token from his pocket so that the effect will be that the door will open automatically for authorised persons.

Title: System for determining the nature of optical distortion in glass
IPC: G01N21/41
Filed: 1974-02-16
Abstract: Disclosed is an optical system for determining whether optical distortion of a piece of flat glass is due to index of refraction variations or contours in major surfaces of the glass. A total optical power profile of the glass and a surface contour profile for each major surface of the piece of glass are made. The total optical power profile shows the optical distortion of the glass along a scan path due to contours in each major surface and index of refraction variations. The surface contour profile shows optical distortion of the piece of glass along the scan path due to contours in the surface of the glass. The surface contour profile for each of the surfaces are summed and the sum subtracted from the total optical power profile to determine an internal distortion profile which shows optical distortion of the glass along the scan path due to index of refraction variations.

Title: Production of high capacity inorganic crystalline base exchange materials
IPC: C01B39/16
Filed: 1976-07-23
Abstract: A method is disclosed for producing inorganic crystalline base exchange materials having high total exchange capacities and specific initial exchange rates which yield well-defined residual concentrations for the elements of Group II of the Periodic Table. The method of the invention includes the concept of controlling the rate of the addition of the reactants and other reaction variables to prevent gel structure formation and to provide a precipitate of discrete particles with a preoriented array of the elements that is predisposed to the final crystalline structure. Recycle of the mother liquor to provide a totally closed system is further disclosed. By preventing the formation of the gel structure it is possible to eliminate cumbersome and costly processing steps and equipment. By varying the precipitation and crystallation conditions, it is possible to control the ultimate crystal size. Recycle allows recovery of the chemical values of the mother liquor and reduces manufacturing cost. Throughput is also significantly increased. Specific and significant process steps include: make-up of the reactants, purification purge of the reactants, precipitation, crystallization, decanting and quench, solids separation and recycle of the mother liquor to provide the closed system. Recycling includes concentration and desalination. The method of the invention further includes particularly unique processing steps comprising solids separation and countercurrent washing.

Patent ES-455764-A1 (ES)
Title: Television camera and pick-up tube having stripes for improved resolution and linearity
IPC: H01J31/46
Filed: 1977-02-09
Abstract: A black-white or color television camera has a pick-up tube having a signal electrode comprising separate strips. Before a line scanning operation to be performed by an electron beam takes place, the signal electrode strips are coupled to a reference potential. After the line scan, the strips which are coupled separately to parallel inputs of a switching circuit which is provided with switches coupled to the parallel inputs, are coupled for supplying video information. This results in a separation between electron beam scanning and picture signal supply by the pick-up tube, which has the advantage that the beam scanning does not affect the picture quality in the direction of line scan. Furthermore, the construction with strips yield an improved signal-to-noise ratio. The switching circuit may, possibly together with a shift register, be integrated in a semiconductor body, which is provided near the signal electrode in the pick-up tube or outside the pick-tube.

Title: Method and apparatus for detecting blemishes on the surface of an article
IPC: G01N21/85
Filed: 1980-02-15
Abstract: A method and apparatus for grading and sorting articles, particularly fruit, according to size, surface blemish and surface color. Fruit is passed sequentially through a camera array which scans the surface of each fruit and measures the intensity of light reflected from successive discrete surface segments. Significant differences between such measured intensities are detected and a measurement of surface blemish is generated in accordance therewith. Size measurements are derived by counting the total number of segments in the surface of each fruit. Color measurements are derived by averaging the ratio of red light intensity to infrared light intensity reflected from each of a plurality of surface areas of each fruit. The fruit are separated and delivered to separate receivers by a mechanism responsive to the size, blemish and color measurements of the respective fruit.
