摘要： A tool turret includes two toothed rims concentric to the rotary axis of its turret head and arranged radially adjacent to one another. One rim is immovable relative to the turret head. The other rim is immovable relative to the turret housing. The teeth of the toothed rims point toward a position-locking member arranged in an axial direction adjacent and coaxial to both of the toothed rims. The toothed rims can be held by a piston which is axially slidable to a position-locking setting, in which its teeth engage the teeth of the two toothed rims without any play. The piston is part of a pneumatic assembly. The angle formed by the sides of each tooth of the toothed rims and the position-locking member is reduced from the conventional value of 60.degree. to a value in which the axial components effecting the tooth components of the tool reaction forces effective peripherally around the turret head is smaller than the sum of the axial force which can be produced by the piston and the axial force latent in the friction between the mating teeth.

摘要： A hollow column is provided for a tool turret with a housing that is to be connected to a machine tool or the like, with a drive motor, and with a tool disc which has receptacles for tools, the tool disc being mounted rotatably relative to the housing and being lockable in selectable angular positions. The hollow column is nonmoveable relative to the housing. A shaft which extends in the longitudinal direction of the column, and which can be driven by the drive motor is disposed within the hollow column. That tool, which is inserted into the receptacle that is situated in the working position, can be driven by the shaft. At least one line is provided in the column so as to be part of a system provided for the transfer of energy, lubricant, coolant, pressure or the like.

摘要： A tool turret has a locking mechanism part axially slidable relative to the turret head with a face gear engaging face gears of the turret head and the housing in its locked position. The axial slidability of the locking mechanism part out of its locked position and the curtailibility of an opposing compression spring allows disengagement of the face gear of the locking mechanism part from at least one of the other two face gears. The force of the compression spring during the load on the turret head arising in disturbance-free operation is greater than the force working through this load on the locking mechanism part in the direction of disengagement of its face gear. In case of a collision with a stress exceeding the load capacity of the tool turret, the force of the compression spring is smaller than the collision force working through this load on the locking mechanism part in the direction of a disengagement of its face gear.

摘要： The invention concerns a pulp grinder in which feed devices force the wood against the grinder stone and in which there is an elevated level of water in the grinding zone. Sealing devices or plates extend between the walls of the wood-supply chutes or pusher chambers and the grinder stone to keep the water level high only in the grinding zone. The sealing plates are adjustable for controlling the liquid level in the grinding zone.

摘要： In a pulping apparatus including a pulper with a rotor near the bottom therein, the pulper has a sluice outlet at the bottom for acceptable pulp suspension. Above the rotor at a corner of the pulper is a second outlet for suspension and dirt. A conduit leads from the second outlet to a horizontally oriented withdrawal apparatus chamber having a suspension agitating rotor at the end of the chamber opposite the entrance for pulp thereinto. A tangential outlet from the withdrawal apparatus chamber lead to a rotary, perforated sorting drum which permits exit of acceptable suspension and which has a rejected suspension and dirt outlet. A valve in the inlet to the withdrawal apparatus chamber is periodically and cyclically opened to permit periodic replacement of the suspension in the withdrawal apparatus chamber, and the suspension which has been agitated in the withdrawal apparatus chamber then moves to the sorting drum.

摘要： For controlling the locking of the rotatable tool holder of a tool turret, the angular position of the tool holder is determined by a rotating transmitter. The rotating transmitter is rotated corresponding to the rotary movement of a control and synchronization device. Digital signals are produced with the aid of the rotating transmitter. Each digital signal is associated with one angular position of those which may be selected. With each of these signals, the indicator is changed in those two angular positions of the control and synchronization device for locking and unlocking of the tool holder at each of its angular positions. The indicator is changed by the rotary movement of the device in one or the other direction out of the associated angular position and into the angular position associated with the locking of the tool holder. These rotary transmission signals are used to control the locking. The control and synchronization device has a first and a second driven part which are nonrotatable relative to the tool holder, and a driving part which is driven when the drive motor is connected. The driving part is coupled with no rotary movement form-locking with one driven part.

摘要： An apparatus for controlling the level and discharge of a suspension or slurry of ground wood in a mechanical wood pulp forming process is described. The apparatus includes, below a wood grinder, a trough in which a slurry of ground wood is formed. The ground wood slurry is passed through a discharge port, which is located near the trough bottom, into a conduit in which a valve is located. The valve is controlled by a slurry level sensor so as to maintain the slurry level at a desired level at least higher than the discharge port. A wood chip cutter is employed at the discharge port and is sized to minimize blockage and facilitate removal of the slurry from the trough. In one form of the invention an apparatus for pressurizing the housing enclosing the wood grinder is described and in another form an open housing structure is shown and described.

摘要： The disclosure relates to apparatus for producing mechanical wood pulp of the type having a grinding stone with at least one wood supply chute in which the wood which is to be ground is pressed onto the grinding stone. A trough or a collecting channel is placed underneath the grinding stone. A water supply device moistens the grinding stone at the grinding zone. At least one closed water tank is set up on the grinding stone in front of the wood supply chute, viewed in the direction of rotation of the grinding stone. The water tank is sealed at least on the side furthest away from the supply chute. The tank has a supply line for pressurized water and has outlet holes directed toward the surface of the stone. Preferably, sealing of the water tank is effected by a sealing plug at the grinding stone which plug is adjustable with respect to the grinding stone to accommodate wear of the plug from the stone.

摘要： The disclosure concerns a process for grinding wood on a grinding stone and the grinding stone which grinds the wood. The grinding stone has a central core, which may be comprised of concrete or steel. The core has a free inner space. A water supply line extends along the free inner space. Outlets from the water supply line are directed toward the periphery of the core at the grinding zone of the grinding layer. Around the core is a grinding layer for grinding the wood. The grinding layer is permeable so that water can be transmitted through it. The permeability may arise from the porosity of the material of the grinding layer itself or through the provision of bores or gaps in the grinding layer. The grinding layer may be comprised of a group of segments covering the core and the gaps may be defined between segments. The core may have bores for delivering the water to the inside of the grinding layer. The water may be heated and/or pressurized for improving grinding.

摘要： A cylindrical tool holder is mounted on a a housing containing a motor, the output shaft of which is coupled through a gear train to a driving ring. One axial face of the driving ring has cam surfaces engageable with cooperating cam surfaces on an axial face of an axially movable locking ring which is spring-urged toward the driving ring. The other axial face of the locking ring has axially facing gear-like teeth which are engageable with mating teeth on a flange formed on the housing and on a ring attached to the tool holder. A lock bolt mounted in the housing and operated by an electromagnet is withdrawn from a ring coupled to the tool holder to permit rotation to a new position and is extended to lock the holder near the new position.
