    摘要: A protective roller screen assembly for helping prevent projectiles moving at a high velocity from passing through a window or doorway. The protective roller screen assembly includes a frame that has a pair of upright members, an upper cross member that extends between upper ends of the upright members, and a lower cross member that extends between lower ends of the upright members. Each of the upright members has inner and outer sides, front and back sides, and an interior that is defined between the sides. Each of the inner sides of the upright members has a guide slot extending therethrough between the upper and lower ends of the upright members. A screen extends downwardly from the upper cross member. Opposed side ends of the screen are slidably disposed in the guide slots of the upright members. The screen is positionable between an extended position and a retracted position. The bottom end of the screen is positioned towards the lower cross member when the screen is positioned in the extended position. The bottom end of the screen is positioned towards the upper cross member when the screen is positioned in the retracted position.

    摘要: Whole (unsliced) fruit or vegetable product is introduced into a chamber wherein an enzyme inactivating environment has been established and which is maintained by a constant flow of a hot dry inert gas. The product is sliced by hot knives into small pieces in the chamber. The sliced fruit or vegetable product is maintained in such environment long enough to completely inactivate the enzymes and then is introduced into a pulper-finisher to macerate the product and separate the puree from the peel and fiber.
