Abstract: A device for at least one self-heated and dense ceramic tube for gas separation. The device includes at least one dense ceramic tube in an environment accessible to a mixture of gases, the at least one tube acting as a diffusion membrane for separating at least one gas from the mixture of gases. Two electrical contacts are provided which allow connecting a power supply to the ceramic tube and driving an electric current through the ceramic tube. The contacts can be in the farm of short coils wrapped around the ceramic tube at difference places. When a voltage is applied to the contacts, an electrical current flows from one contact to the other through the ceramic tube. The current in the ceramic tube heats the tube. Thus, the tubes heat themselves. The hot tube allows separating a gas from the mixture of gases. The driving force for the diffusion is achieved by a pressure difference generated by pumping at the side of the separated gas and pressing at the side of the mixture of gases.

Abstract: A long-timber chipping machine has a timber feed channel for receiving longitudinally arranged timbers, advanced using a timber-advancing device to a vertically movable chipping device positioned at the downstream end of the feed channel. The chipping device has a rotatable cutter ring equipped with chipping cutters on its cylindrical inner wall, which defines a chipping chamber. The chamber is aligned with the downstream end of the feed channel. To improve the chipping, a curved timber-receiving plate projects into the chipping chamber from the downstream end of the feed channel, which also has a matching curved base. The curvature of the plate and the base match the curvature of upper cylindrical inner wall of the cutter ring so that the upper cylindrical inner wall can be lowered closely to the plate, leaving only a very small clearance and exposing all of the timbers to the chipping cutters.

Abstract: An improved knife clamping system for use in an apparatus for processing wood, such as a flaker, chipper or waferizer, that employs a rotary disc or ring, cutting knives, holding locations mounted on the disc or ring to receive the cutting knives, clamping members to engage and hold the cutting knives in position and fasteners to mount the clamping members to the holding locations. The improvement comprises providing a surface having an undulating profile to engage against the cutting knives. The undulating surface can be formed on the clamping member, at the holding location or at both locations. The surface is shaped to deform to engage the cutting knives with a uniform clamping load upon securing of the fasteners to a pre-selected torque. The foregoing arrangement requires fewer fasteners while still maintaining an adequate clamping force on the cutting knives. This makes parts less expensive and reduces the time to change the knives as there are fewer parts to loosen and tighten.

Abstract: A ring flaker has a housing with a back opening so that a blade ring mounted to an arbor assembly can be slid backwards away from the housing to allow the blade ring to be replaced without removing the housing.

The back opening in the housing is of sufficient size to permit the blade ring to be axially withdrawn. The arbor assembly has a slide arrangement on the ring flaker carriage and there is provision to use a hydraulic jack to move the arbor assembly on the slide arrangement for a distance sufficient for the blade ring to be disconnected for removal and replacement.

Abstract: A device suitable for the continuous feeding of wood pieces of approximately the same length into flaking machines comprises a feed trough opening into the flaking machine, behind which there is arranged a loading magazine whose cross section agrees with the feed trough. The lengths of wood are shaped into compact piles, which are then advanced cyclically into the flaking machine by means of a pushing plate. In order to be able to bring the pushing plate back over the log pile already prepared for further processing inside the loading magazine, the pushing plate is able to be slewed upon a support that can be moved parallel to the floor of the device, over both the feed trough and the loading magazine. Control members attached to the pushing plate interact for short intervals with stationary control paths at the beginning and end of the return trip of the pushing plate to cause the plate to tip either into its withdrawal position or into its pushing position.
