Title: Side feed tundish apparatus for the alloying and rapid solidification of molten materials
Inventor: GASPAR THOMAS
IPC: B22D11/06
Filed: 1990-06-01
Abstract: ABSTRACT    The invention relates to a method and apparatus for improving the flow control of molten material (30) in a tundish.  The improvement is accomplished by a perpendicular turn in the path of flow of the molten material as the flow leaves an intermediate section (34) of the tundish or casting receptacle and overflows transversely an exit lip (36) to thereby contact a heat-extracting substrate (38).  The perpendicular turn in the flow achieves improved control of the molten material's velocity profile, cooling rate, and depth and flow uniformity of the molten material in the casting receptacle.  The essentially perpendicular turn in the path of the molten material from the intermediate section causes the molten material to initially approach the exit lip in a transverse direction unlike conventional laminar or direct delivery molten flow. The transverse flow relative to the direction of the exit over-flow toward the casting or cooling surface facilitates improved mixing of the molten material or two materials to be alloyed, improved control of the depth gradient, and improved control of the velocity into the exit lip.

Title: Process for forming a polyester film
Inventor: ITO TATSUYA
IPC: B29K67/00
Filed: 1991-12-12
Abstract: ABSTRACT OF THE DISCLOSURE     A polyester film, which is substantially non-oriented and whose main component is polyethylene terephthalate, is formed as a some shape, for example, a package, at a condition causing no yield point.  The formation ability of the polyester film for forming is improved, and a formed body having a good uniformity in thickness can be obtained.  Further, the range of the temperature condition causing no yield point can be enlarged by laminating a PET-system polyester, which originally tends to cause a yield point by itself, onto a polyester having no yield point.  In such a laminated polyester film, the slipping property and releasing property from a mold of the film can be improved by specifying the ranges of the degree of crystallinity of each layer, the adhesive force at a high temperature of the film and the surface roughness of the film, and the shape of a formed body can be improved.

Title: Carbonated beverage container
Inventor: JAMIESON JAMES G
IPC: B65D47/36
Filed: 1990-12-20
Abstract: When dispensing carbonated beverages, particularly beer and draught stout, it is desirable to obtain a close-knit creamy head.  This contributes to a creamy taste and adds considerably to the customer appeal. To obtain this effect when dispensing from a can (1) it includes a lid (2) having a secondary compartment (4) formed on it and a non-resealable closure (3) in communication with the secondary compartment. At least one orifice (5) extends between the secondary compartment (4) and the inside of the container (1), and a liquid (8) is held in the secondary compartment. The container is arranged so that on opening of the closure (3) the pressure in the secondary compartment (4) is reduced to atmospheric with the result that gas or liquid from the main body of the container (1) is jetted through the at least one orifice (5) into the liquid (8) in the secondary compartment (4) to generate a foam in the secondary compartment. Complete opening or removal of the closure (3) enables the contents of both the secondary compartment (4) and the remainder of the can (1) to be mixed and dispensed together so that the foam produced in the secondary compartment acts to seed the generation of small bubbles throughout the beverage (8) in the can (1).

Title: Hydroentangled fabric diskette liner
Inventor: HOWEY JON A
IPC: G11B23/02
Filed: 1992-10-13
Abstract: ABSTRACT         A nonwoven liner for a diskette cartridge is made of hydroentangled fibers and impregnated with a small amount of binder which is uniformly distributed throughout the fabric.  The binder comprises no more than 5% by weight and preferably between 1.5 - 3.0% by weight of the fabric.  The low concentration of binder ensures that the liner surface does not become totally coated with plastic film that reduces cleaning ability, while also providing  improvements  in tensile  strength  and debris reduction.   The binder solution preferably has a high surface tension  (low surfactant level),  so that the binder becomes concentrated at the junction points of the fibers throughout the fabric.   The low level of surfactant ensures a low risk of chemical attack of the disk media surface.  The hydroentangled fabric cleans the disk media more efficiently, has less fiber debris,   contains   less   environmental   contaminants,   is substantially  loftier,  and  is  cut with  cleaner  edges  than standard thermally bonded diskette liners.

Abstract: A diffraction element is positionally adjusted on a calibrating optical head arrangement while an objective lens is positionally adjusted so as to maximize a total signal   calculated   in   a   photodetector,   whereby  a predetermined focusing error signal and tracking error signal are obtained. The thus adjusted diffraction element is adhesively secured on a package housing a light source and a photodetector to form a light source unit.  The thus prepared light source unit is positioned on and assembled into an optical head by angularly adjusting the light source unit and an objective lens on the optical head individually so that both the optical axis of the light emitted  from the  light  source unit  to  incident  on  a recording medium and the axis of the objective lens are aligned normal to the recording medium and by aligning the optical axis of the objective lens with the center of intensity  distribution  of  the  incident  light  on  the objective  lens.     This  configuration  eliminates  the necessity of mechanical parts  in the optical head for adjusting the diffraction element and the necessity of a space for the adjustment, so that it is possible to promote a small and light weight optical head.   In addition, by effecting the optical adjustment when the light source unit is assembled into the optical head, error signals can be adjusted.  Therefore, the adjustment step can be omitted.

Title: Setup for the transformation of husbandry dung to the manure
Inventor: CHANG DAO-PIN
IPC: E03F5/14
Filed: 1993-06-18
Abstract: The Setup for the Transformation of Husbandry Dung to the Manure ABSTRACT OF THE DISCLOSURE      This original work is a setup for the transformation of the most criticized husbandry dung pollution to the economically feasible use.  The setup is especially effective in handling the dung pollution in the area.   It applies a base unit with a special circulational filtration net (called the upper- and the lower-net) mounted on the unit top.  The upper-net contains a   shape rectangular declined plate and a wind cover.  The interior of the wind cover contains a blower and a water adsorption apparatus.  The back side of the lower-net also contains a blower (for clean up the operational residues).   When the excretion material (liquid) flow through the   shape declined plate it will disperse according to the local land shape.  Through the transportation by the net, the liquid will come into the wind cover, being affected by the blower and the water adsorption apparatus, and instantaneously separate the liquid from the solid material.   The mid-layer of the base unit also contains two cylinders to collect the excretion material and the dry dung (or, any other mixed materials) after the filtration.  In addition, the lower part of the base unit is constructed with the continued spiral plates and the rotational shape horizontal stirring bars.          Through the pushing by these spiral plates and the stirring, blending and mixing by the stirring bars the mixture is directly transferred into an air-tight warehouse for several days to produce the organic, the organic manure.  The waste water after the filtration can use the filtrated material on the bottom of the  treatment tank,  in  conjunction  with  the  parallel  and repeatable stirring cylinders to homogeneously and continuously mix the sewage and waste water so that the waste water (more or less contains some residues)  and the solid material  can be separated by either filtration or precipitation.   The solid material can then be solidified to produce the piled fertilizer.          The characteristics of this setup is to produce the economic manure to keep up with the husbandry activities and to avoid the environmental pollution problem.   The costs for the setup is cheap (Based on the price in ten years ago, the present available setup is at NTD 2,000,000+/2,000 heads of hogs, a heavy costs for the farmer.).
