Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a method of fabricating a bottle-shaped container of saturated polyester having superior mechanical strength, very small age and high temperature deformation degree, and superior dimensional stability.  The piece for forming the bottle-shaped container is heated to an orientation temperature is biaxially oriented in a blowing mold and is then thermally set by making the outer wall surface of the expanded container with the inner wall surface of the mold retained at the temperature of the range from the glass transition point to the crystallization temperature longer than 5 seconds.  The blowing mold is formed with the size adjusted in capacity by approx. 6% of shrinkage of the product container when the container is exposed at high temperature of higher than 70°C and is then left to stand for to thereby obtain the container of accurate capacity.

Abstract: ABSTRACT Method and apparatus for blow molding plastic articles from preformed parisons by reheating the parisons and then stretching and blowing them. The parisons are conveyed in series to a plurality of fixed heating stations at which the parisons are fixedly positioned for heating, the parisons being rotated for uniform heating. The heating is enhanced by blowing air under pressure through a tunnel enclosing the successive heating stations. Finally, the parison is stretched and blown at a blow station in a blow mold of unique design.

Abstract: Abstract of the Disclosure A high efficiency laser spectrum conditioner for generating a collinear parallel output beam containing a predetermined set of frequencies from a multifrequency laser.  A diffraction grating and spherical mirror are used in combination, to disperse the various frequencies of the input laser beam and direct these frequencies along various parallel lines spatially separated from one another to an apertured mask.  Selection of the desired frequencies is accomplished by placement of apertures at locations on the mask where the desired frequencies intersect the mask.  A recollimated parallel output beam with the desired set of frequencies is subsequently generated utilizing a mirror and grating matched and geometrically aligned in the same manner as the input grating and mirror.

Abstract: ABSTRACT OF THE DISCLOSURE         A biological waste water treatment carried out in a single tank.  The conditions in the tank are controlled to provide a biological reaction zone containing waste water and biodegrading organisms and an overlying clarification zone from which an effluent of treated waste water flows.  To maintain these conditions, a recycle stream is continuously withdrawn from the biological reaction zone, passed through an oxygen-dissolving device, and supplemented with influent raw waste water and the supplemented stream returned to the reaction zone.          The oxygen in the biological reaction zone is monitored and supplied to the oxygen-dissolving device in an amount to satisfy the demands of the organisms and, at the same time, to keep the oxygen in solution.  For preferred results, the supplemented recycle stream is continuously injected, at one vicinity, along the bottom of the biological reaction zone in a horizontal shallow inflow having a width substantially greater than its depth and at a flow rate considerably greater than that of the raw influent.  The recycle stream is withdrawn from near the bottom of the reaction zone, at a vicinity remote from that of the inflow, in an outflow having a substantially greater width than its depth.  In this way, there is created, between the inflow and the outflow, a horizontally relatively fast flowing undercurrent of initially high dissolved-oxygen content, and having an extensive uninterrupted interface with an overlying relatively quiescent body of mixed liquor flowing upwardly relatively slowly.

In a data processing system comprising at least two microcomputers, one microcomputer (1) serves as a master to control the or each other microcomputer (2, 3 respectively) as a slave. In order to improve that utilisation of the system the bus (4) of the master serves as a common bus and each slave has associated with it a buffer memory (5, 6 respectively) for the inter-mediate storage and transmission of data. The buffer memory can be connected, by means of an associated switching device (7, 8 respectively), alternately to the bus (9, 10, respectively) of the slave and to the common bus thereby switching the address field constituted by the buffer memory into the address space of the slave and into the address space of the master respectively. Further-more, each slave has associated with it two interconnected input/output interfaces (11, 12 and 13, 14 respectively which serve for transmission of status signals concerning the master of the relevant slave. One of said interfaces is connected to the common bus, while the other interface is connected to the bus of the relevant slave. Each switching device is controlled by the corresponding input/output interface connected to the common bus, and hence by the master.

When the mandrel is being inserted, the seals are disposed at the smaller ends of the ramps so as to minimize frictional resistance to the insertion.  The seal that is inserted first will tend to move, under frictional forces, to the small end of the ramp, being returned to the large end by the force of the hydraulic fluid during a subsequent swaging operation.  The other seal member, however, is urged toward the small end of the corresponding ramp by a spring that is overcome by hydraulic forces once the swaging begins.
