    Abstract: A decorticating device formed in a manner similar to a disc refiner but having pins on the rotating and fixed discs sloped radially and tangentially to facilitate the travel of the flax through the space between the discs as they are relatively rotated, i.e. all the pins slope radially outward, the pins on the rotating disc also slope rearwardly relative to the direction of rotation while those in the fixed disc slope forwardly in the direction of rotation whereby a high throughput together with ample decortication of the fibre is obtainable.

    Abstract translation: 一种脱皮装置,其形式类似于盘式精磨机,但在旋转和固定盘上具有径向和切向倾斜的销,以便当亚麻相对旋转时,亚麻通过盘之间的空间行进,即所有的销都径向倾斜 向外,旋转盘上的销钉也相对于旋转方向向后倾斜,而固定盘中的销钉在旋转方向上向前倾斜,从而可获得高通量以及纤维充分剥离。

    Abstract: A one piece carton is described having a central divider with a handle formed of two foldably interconnected parts. The handle is detachably connected to the partition by frangible lines of weakness and is retained in position by a pair of flaps integrally, foldably connected to the partition and overlying lateral flanges of the handle to trap the handle between the flaps and the partition.

    Abstract: In this method of making corrugated board the board formed by the application of the liner to the single-face is passed between two metal surfaces, both heated to a suitable temperature. The temperature of the metal surface in contact with the liner is about the same as, or preferably somewhat higher than, the temperature of the other metal surface. In a corresponding apparatus the surface applying heat to the single-face is constituted by an endless moving metal belt, e.g. made of fatigue-resistant rolled spring steel.
