Granted: 1998-05-05
Abstract: A process  for the  production of chlorine dioxide by reacting an  alkali  metal  chlorate,  mineral  acid  and a reducing agent in such proportions that chlorine dioxide is produced in a reaction  medium  which  is  maintained  at a temperature of  50°C -  100 °C  and at  an acidity within a range of 2 - 12 N and which is subjected  to subatmospheric pressure  sufficient  for  evaporating  water. A mixture of chlorine dioxide and  water  vapour  is  withdrawn  from an evaporation zone  in the  reaction vessel, and alkali metal sulphate is precipitated in  a crystallization  zone in the reaction vessel.  The precipitated alkali metal sulphate is contacted with a saturated  water solution  of alkali metal sulphate  whereafter   neutral  alkali  metal  sulphate  is precipitated and dissolved in water. The  water solution is brought  to  an  electrochemical  membrane  cell  in  which sulphuric acid  is  formed  in  the  anode  compartment and alkali metal hydroxide in the cathode compartment.

Title: Dispensing device for dispensing at least two fluids
Inventor: HOLM NIELS ERIK
IPC: B05C17/01
Filed: 1992-09-30
Granted: 2004-07-13
Abstract: A dispensing device for dispensing at least two fluids comprises a housing of a pistol-like configuration having an integral handle, in which a spring-biased trigger is received. Within the housing of the dispensing device, two syringes are received and fixated, which syringes contain respective fluids to be accurately dispensed. Provided a cover of the housing is closed, the motion of the trigger relative to the handle is transmitted to a toothed rack which cooperates with a propeller body in a ratchet-like manner.      The ratchet-like cooperation allows a uni-directional motion of the propeller body and prevents a motion of the propeller body in the opposite direction. Provided the cover is not closed, the motion of the trigger relative to the handle is not transmitted to the propeller body, and any unintentional dispensing of fluids from the dispensing device prior to the preparing of the dispensing device for use by closing the cover is consequently prevented.

Abstract: A multi-vane structure (8) for incorporation in an aircraft gas turbine engine has vanes (9) of complex geometry made of braided fibers which are continuous about the cavities defined by the vanes.  These complex geometry parts are prepared by providing a plurality of removable mandrels (14a, 14b), stacking the mandrels along a horizontal axis (18) in a cavity end (15b) to cavity end (16a) configuration, braiding (23) about the mandrels, cutting the mandrels adjacent the cavity end faces (17), side stacking the mandrels so the faces are placed in a parallel orientation and molding.  Utilizing braided fibers instead of hand lay-up woven fibers eliminates seams and produces cavities having continuous fibers about the periphery thereof which substantially increases the strength and dimensional reproducibility of the part.

Abstract: A process for paving a surface of a sub-base with compactable asphaltic concrete comprising aggregates and an asphaltic cement to provide a finished asphaltic pavement having dormant zones of potential fracture at predetermined locations.      The process comprises the steps of forming a continuous mat of compactable asphaltic paving concrete having a predetermined thickness on the surface of a sub-base; creating dormant zones of potential fracture at predetermined locations in the mat prior to compacting the compactable asphaltic paving concrete; and compacting the mat of compactable asphalt concrete to seal the dormant zones and provide a finished asphaltic pavement of predetermined density having a smooth traffic bearing top surface with the sealed dormant zones of potential fracture substantially concealed therein.      The invention also includes the finished asphaltic pavement produced by the process of forming a mat of compactable asphaltic paving concrete on the sub-base surface. The process creates dormant zones of potential fracture at predetermined locations in the mat prior to compacting the compactable asphaltic paving concrete. The process further involves compacting the mat of compactable asphalt to seal the dormant zones and provide a finished asphaltic pavement of predetermined density having a smooth traffic bearing surface with the sealed dormant zones of potential fracture substantially concealed therein.

Granted: 2005-09-20
Abstract: A self-positioning light fixture with a stabilizing base comprises a self-righting member in the shape of a spherical segment and a separate lamp supporting member with connecting means to join the two together and to separate each from the other. then separated, a filling neck or spout on the top wall of the self-righting member is exposed through which fluid ballast material such as sand may be poured into the cavity of the self-righting member. The filling neck has external threads to engage the internal threads of a recess opening to the bottom wall of the lamp supporting member when received therein to thereby couple the two members together. Additional fastening screws are provided to more securely connect the self-righting member to the lamp supporting member. A shook absorbing mechanism is provided comprising mounting springs to secure the lamp bulb socket member to the lamp supporting member and thereby protect it from shocks transmitted to the lamp fixture. The spherical segment self-righting member when filled with ballast material and connected to the lamp supporting member will rotate the fixture back to its upright position if tilted away therefrom. A flat bottom wall of the spherical segment self-righting member stabilizes the fixture on its upright position.

Abstract: An improved color picture tube includes an evacuated glass envelope having a faceplate panel with a cathodoluminescent screen comprising different color-emitting phosphor elements disposed thereon. The panel includes a shadow mask-frame assembly mounted therein by support means located at peripherally spaced positions within the panel.      The shadow mask includes an apertured portion, the apertures of which are in register with the phosphor elements of the screen. The support means at each spaced position includes a stud attached to the glass envelope, a spring having an aperture therein for engaging the stud, and a plate welded between the spring and the mask-frame assembly.      The improvement comprises mechanically joining the spring and the plate by extrusions interlocking the parts together at two-spaced apart locations along one edge of the parts, whereby the spring and the plate are in contact along at least a portion of the facing surfaces thereof. The interlocking extrusions render the spring and plate resistant to shock induced movement, thereby minimizing misregister between apertures in the mask and the phosphor elements of the screen.

Granted: 2002-07-23
Abstract: The invention relates to a method for a unique control of the frequency and output power of a digital generator, in particular for an ultrasonic welding process. Based on a digital processing, the method according to the present in-vention compensates not only for variations of the resonant frequency in a broad range, but further provides to control a shifting of the resonant point during the welding process in response to temperature or pressure variations. Power variations caused by variations of the line supply voltage or by the pressure are detected and levelled out by the software. The software monitors the overall operation of in-line machinery, matches its parameters and monitors the complete cycle. The software further ensures an optimum efficiency and effectively protects the end stage against stress caused by high-reactive currents.
