Title: Stretched styrene-based resin moldings and a process for production thereof
Inventor: NAKANO AKIKAZU
IPC: B29C55/00
Filed: 1988-12-02
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE    Stretched moldings (e.g., stretched films, sheets or bottles) of styrene-based resins (e.g., polystyrene) having mainly syndiotactic configuration and a weight average molecular weight of at least 50,000, and a process for the production thereof are disclosed.  The stretched moldings are obtained by uniaxially stretching the styrene-based resins at a draw ratio of at least 2 times, or biaxially stretching at a draw ratio of at least 1.2 times in each direction.  The stretched moldings are excellent in heat resistance, chemical resistance, solvent resistance, electric insulating properties, mechanical strength and so forth, and thus can be used as food wrapping materials, housing materials for electric or electronic parts, and so forth.

Abstract: ABSTRACT OF DISCLOSURE    An oven for preheating glass containers in which the containers are moved through the oven on a conveyor with the conveyor moving at a linear speed that is in excess of the permitted speed of the container movement.  This permits the containers to produce a "gear effect" rotation of the containers that are guided on the conveyor by side rails that are spaced apart a distance greater than the container diameter.  A source of heated air is directed against the shoulder of the container by an adjustable nozzle and another nozzle is directed against the heel so that these areas of the container will be preheated so that the shrinking of a plastic label about the container will be uniform.

Abstract: A beverage brewing machine which has upper (11) and lower (25) brewing chambers which are moveable relative to each other so as to clamp a strip-shaped filter (36) therebetween during the brewing process and the chambers can be separated so as to allow the filter strip to be removed from the brewing chamber and the beverage residual wiped therefrom after which the filter strip is returned to the brewing chambers which are then resealed for the next cycle. A hold down grid (20) engages the top surface of the filter (36) to hold it down as a piston (26) moves in the lower chamber (25) upwardly to force air through the filter to agitate the beverage. When the piston reaches top dead center, the hold down grid (20) is lifted. When the piston passes the opening the brewed coffee is poured. A loose connection is provided between the connecting rod for the piston and the driving crank arm so that the piston remains longer at the top and bottom of its stroke. Due to agitation of ground and oxygenation of the mixture, or a combination of both, by adding a high volume of air during the brewing process, increased extraction results. <IMAGE>
