Abstract: Abstract of the Disclosure Gas diffusion elements, formed of a body of solid particles which have been shaped, pressed and rendered coherent by bonding or nintering in a compacted form having pores, are disclosed.  Said elements include a peripheral, annular zone of relatively small proportions having lesser permeability, greater density or lesser height lesser permeability, greater density or lesser element.  In accordacne with the invention, a boundary zone is provided adjacent to and inwardly of the peri-pheral zone, in which boundary zone there is a progresive increase, continous ration of the element, in the direction metric compression ratio of the element, in the direction of the peripheral zone, or towards a vertical surface which is near the periphery of the element.  Such ele-ment may provide improved gas, e.g. oxygen transfer efficiency and therefore holds promise of improving the efficiency and economics of gas transfer processes, such as for instance treatment of sewage or other waste water with air, oxygen and/or ozone.

Abstract: ABSTRACT OF THE DISCLOSURE       Since an ordinary semiconductor laser heretofore employed has no mechanism for stabilizing the lateral mode, the light emitting region becomes wider as current increases.  That is, the lateral oscillation mode is un-stable.  In the present invention, a current rejecting layer and an etch-back preventive layer are added to a semiconductor laser provided with a cladding layer composed of a projecting portion for confining light from an active layer and a portion for emitting light.  The thicknesses of predetermined layers, the relationships of forbidden band widths of the layers and their conductivity type are specified.  By these measures, an excellent current limit function and optical guide function can be obtained and the lateral mode can be stabilized.

Abstract: ABSTRACT OF THE DISCLOSURE      A material container for bulk material having a follower disposed therein.  The diaphragm of the follower is coextensive with the transverse cross-section of the container.  During the removal of bulk material from the container, the follower moves downwardly in constant engagement with the upper surface of the bulk material for wiping the interior surface of the container and for applying a downward force on the bulk material.  When bulk material is being discharged into the container for the filling thereof, the follower may be held at the upper portion of the container.  A central access opening is formed in the top wall of the container and a central opening is formed through the diaphragm of the follower directed in the axial direction of the container.  A tube through which bulk material is conducted into the container for passage below the flexible follower is fixed to the follower in communication with the central opening thereof and is arranged to receive bulk material having passage through the access opening of the container.

Abstract: ABSTRACT OF THE DISCLOSURE          Biaxially oriented low cost polyolefin bottles of improved optical clarity, gloss, and strength, and useful for packaging materials such as liquid detergents, shampoos, pharmaceuticals and intravenous solutions, are prepared by stretch blow molding polypropylene homopolymer co-polymer and allomer parisons or preforms which are formed from low temperature  melts at temperatures just above the melting points of the polymers and allomers, and are injected at constant rates against cold polished mold surfaces at relatively low pressures and at slow rates to avoid melt fractures.  Melt temperatures of from 490° to 700° F. are preferred for poly-propylene blow mold type polymers and allomers.  Polished beryllium copper mold surfaces are desired for high luster gloss finishes.  Mold temperatures of from 30° to 80° F. are preferred.  Injection molding with a high compression ratio of 3 to 3.5 for insuring a homogeneous melt is preferred with a relatively slow injection rate to fill the mold cavity of about 3 to 10 seconds.  The low temperature  molding limits the size and increases the number of spherulites that form as the melt cools and solidifies thus minimizing crystallinity in the parison.  The low mold temperatures provide faster molding cycles, increasing production and reducing costs but the injection rate is sufficiently slow to avoid melt fracture.  The stretch blow molding is preferably conducted at temperatures just below the amorphous flow temperature of the parison with temperatures of about 295°F. being sufficient for the polypropylene copolymer and about 325° F. being satisfactory for the polypropylene homopolymer.

Abstract: TITLE                   HUMAN AND ANIMAL TISSUE PHOTORADIATION SYSTEM ABSTRACT    A tissue photoradiation system uses a hematoporphyrin or hematoporphyrin derivative dye in tissue to be irradiated and arranges a xenon ion laser 10 for simultaneous lasing.  Deep blue light is produced at wavelengths of about 406-427 nanometers and red light at a wavelength of about 627 nanometers by using partially transmitting mirrors arranged at opposite ends of the laser resonator.  One of said mirrors has a coating that substantially reflects blue light and partially transmits red light to produce a red light output, and the coating of the other mirror substantially reflects red light and partially transmits blue light producing a blue light output.  The blue light output is transmitted to a diagnostic tissue irradiator to illuminate the tissue and diagnose its condition.  A trans-mission system  using an optical fiber delivers the red light to the tissue for treatment purposes.  The red light is radiated out the side of an optical fiber region to be directed into large area of tissue.  In the foregoing manner, the invention provides the means whereby a single laser can simultaneously provide both frequencies required fox diagnosis and treatment, whilst maintaining the necessary level of convenience and economy for practical application.

Abstract: APPARATUS FOR SELECTIVELY TRANSFERRING DATA BETWEEN REGISTERS     ABSTRACT OF THE DISCLOSURE         Apparatus is provided for selectively transferring data from one to another of a plurality of display registers.         Selector switches are associated with respective ones of the display registers, each selector switch being manually operable so as to be designated either as a source switch or as a destination switch, whereby the data in the display register associated with the source switch is transferred to the display register associated with the destination switch.  A central processing unit is responsive to the operation of a first of the selector switches followed by the operation of a second of the selector switches to transfer the data from the display register associated with the first selector switch to the display register associated with the second selector switch.          Preferably, indicators are associated with respective ones of the selector switches; and the central processing unit controls the indicator associated with the first-operated selector switch to provide a distinctive indication represent-ing that this selector switch has been designated as the source switch.         A desired application of this invention is in video editing apparatus that is used with video playback and record-ing devices in which video information that is reproduced from one device is recorded on the other.  In such an application, the data in the respective display registers is position data representing relative positions of the record media of the playback and recording devices.  Such display registers constitute a present position register for displaying the present position of one of the record media, a "start" register for displaying the position at which the start of an edit operation is to commence, and a "stop" register for displaying the position at which the edit operation is to end.
