Title: Method of and a grinder for grinding wood under pressure
IPC: B27L11/00
Filed: 1979-09-08
Abstract: A method of grinding wood under pressurized conditions in a grinder according to which wood is fed in batches into a pressurized gas-filled grinding chamber provided with a rotary grinding means. The wood batches are fed through a feeding chamber provided with means for sequentially opening and pressure-tightly closing said feeding chamber from two sides in and respectively out of communication with the atmosphere and said grinding chamber respectively. The groundwood stock is discharged from the grinding chamber through a pressure lock formed by the groundwood stock. In this way feeding of the wood batches into the grinding chamber and the discharging of the groundwood stock out from said grinding chamber are carried out as sluicing steps, whereby a continuous pressure can be maintained in the grinding chamber in spite of feeding of new wood batches and discharging of groundwood stock.

Title: Method for varying the width of a slab cast in a continuous-casting mould
IPC: B22D11/00
Filed: 1985-09-23
Abstract: A method for varying the width whereby the width of a slab which is being cast is varied by means of a movement of the narrow faces of a continuous-casting mould by activation of a horizontal actuation device and of a rotary actuation device which can be actuated independently of the horizontal actuation device.

The acceleration of the horizontal movement of each narrow face is determined by means of the permitted resistance to deformation of the skin as a parameter for each period. The angular speed of the rotary device or the difference in speeds between the upper and lower ends of the narrow face are also determined. The operation for varying the width is carried out while maintaining the acceleration and the angular velocity or the difference in velocities at constant levels in the respective periods.
