Abstract: Abstract of the Disclosure A doctoring surface conformation for applicator nozzle structures in photographic film cassette contained processors by which a coating of processing fluid may be deposited on a moving run of an exposed film strip. The doctoring surface conformation is defined as a planar surface spaced in parallel relation to the film strip which is urged toward a pair of guide tracks positioned on opposite sides of the planar surface. The sides or edges of the doctoring surface are delimited by vertical walls converging in the direction of film strip travel so as to develop a suitable hydrodynamic force in the processing fluid  ?le minimizing the capture of minute foreign particles such as dust which may be carried on the surface of the film strip to be coated.

Abstract: CENTRIFUGE ASSEMBLY      ABSTRACT An improved centrifuge assembly comprising a channeled rotor assem-bly and a fluid container disposed in the channel, whereby the centri-fugal separation effects in the fluid container are determined by the geometry of the channel in the rotor.  This arrangement is particularly useful for two-stage blood platelet separation.  The fluid container is preferably formed from semirigid plastic material and is considered a disposable item to be discarded after a single use.  The rotor assembly preferably includes a removable filler piece or center piece formed from a single piece of material, such as rigid plastic, as by machining or molding, and having therein an open-topped channel having dimensions appropriate to receive the semirigid container, which is suitably curved and placed in the channel.  Fluid connections are provided from a multi-chambered cavity attached to the ends of the container to an axially located multi-channel rotating seal.  The connections lie in a plurality of radial slots in the filler piece.  The channel is divided into two distinct portions, the first portion of the channel being circular, and the second portion being spiral-like and having a plurality of radiuses, each measured from a different center, the spiral increasing radially outward from its juncture of the first stage and the second stage.  A transition section connects the two portions, and forms a spillway be-tween the two portions.  The channels are proportioned and arrayed so that the centrifuged red cells move toward the outer wall of the first portion, from whence they retroflow to an entry chamber and thence to a fluid connection by which the red cells are drawn off.

Abstract: ABSTRACT         VAPOR PERMEATION TIME-TEMPERATURE INDICATOR            A time-temperature indicator (t-T indicator) is described which is useful for monitoring the shelf lives of various perishable articles.  The device is constructed of a vapor-permeable barrier positioned between a vapor and an indicator, both housed in a vapor-impermeable con-tainer.  The device is activated just prior to the monitoring period by providing vapor to the container, as for example, by rupturing a solvent-filled frangible reservoir.  The indicator, upon contact with the vapor produces a visual color response, and the vapor is constrained to permeate through the vapor-permeable barrier before contacting the indicator, thus creating a characteristic induction period before a color response occurs.  The time required for the color response to occur in the device is a function of the temperature and time. The induction period can be varied by the thickness and type of material of construction used for the ~ ~ vapor-permeable barrier, the nature of the vapor and the nature of the indicator employed.

Abstract: Abstract A coil carrier for thread or yarn comprises parallel carrier elements interconnected at a spacing from each other by coupling members to define a common cylindrical enveloping surface.  The supporting elements are circumferentially compres-sible and the coupling members are substantially inflexible so that, on the application of radial pressure, the carrier diameter is reduced without markedly changing the spacing between the carrier elements.  Said spacing is larger than the circumferen-tial dimension of each carrier element.

Abstract: ABSTRACT OF THE DISCLOSURE           A halogen, such as chlorine, is generated in an electrolysis cell in which at least one of the cell electrodes is bonded to the surface of a solid but porous membrance which separates the cell into anode and cathode chambers.  A pressurized aqueous metal halide such as brine is electrolyzed at the anode to produce chlorine.  Brine anolyte and sodium ions are hydraulic-ally transported across the porous membrane to produce caustic soda (NaOH) at the cathode.  By bonding at least one gas-permeable, poroud electrode to the hydraulically-permeable membrane, the cell voltage for electrolysis of brine is considerably lower than that required for asbestos disphragm cells, while achieving high cathodic current efficiencies by minimizing back migration of caustic soda to the anode.

Abstract: abstract The "SANI-SCOOP" is manually operated tool for convenient? and quickly picking up dog excrement.  It is known to have a trap door which is normally closed when not in use, but will open automatically when in use to allow the dog excrement to pass through and to be received into an attached disposable plastic holding bag. The design of the tool is such that a handle enables the user to place the operating head to the ground just behind the dog excrement to be picked up, whereby the weight of the tool will activate the opening mechanism of the trap door.  A forward sweep of the tool by the user will dispose the dog excrement into the disposable plastic holding bag.  When the tool is lifted from the ground, the trap door will automatically close and seal off the opening to the holding bag.  The faster the forward sweep of the tool, the less chance there will be of dog excrement collecting on the operating head.  If some excrement collection does occur, it will be easily removed by first removing the disposable plastic holding bag and then placing the head of the tool into a domestic toilet, whereby one or two flushings will remove any excrement that may have collected.  By installing a new disposable plastic holding bag, the tool will then be ready for its's next usage.

Abstract: ABSTRACT OF THE DISCLOSURE    A process for the selective recovery of sodium citrate from a solution utilized as the absorption medium in a closed loop absorption/stripping process for the recovery of sulfur dioxide (SO2), is described herein. This sodium citrate recovery process is characterized by taking a slip stream from the circulation loop and sending it through a cooling device.  It is then cooled to a temperature of 14°C, or lower, which causes the precipitation of sodium sulfate.  The precipitate is separated from the mother liquor and thereby removed from the system.  The mother liquor is then heated (to a temperature of at least 40°C.)  such that water can be evaporated, resulting in a system volume reduction to less than 20% of its original or more preferably to less than 10%.  This will cause the precipitation of sodium citrate thereby permitting ease of separation and return back to the absorbant solution.  The remaining mother liquor is then further, slowly, cooled to about 25 to 40°C, where additional sodium citrate is precipitated and separated.  Finally, the remaining mother liquor, which is almost barren of sodium citrate and sodium sulfate, can be totally or partially removed from the system.
