Patent SE-434616-B (SE)
Title: Cutter arrangement
Inventor: CARLSSON J E K
IPC: B27G13/04
Filed: 1980-06-03
Abstract: In a cutter arrangement a plurality of edged tools 13 are situated each in their own cavity 7, evenly distributed about the periphery of a rotating cutter drum 3. In each cavity 7 there is a holder 15 which, thrusting against the front wall 11 of the cavity in the direction of rotation, firmly clamps the edged tool 13 against the back wall 9 of the cavity. The holder 15 contains a rotary set screw 21 and a support device 23 which can be adjusted in the direction of the rear wall by the screw 21. In order to make it possible for even inexperienced personnel to easily achieve an exactly balanced clamping force at each set screw 21, the screw 21 extends in the direction from the mouth 19 of the cavity into the cavity and is accessible for tightening by means of a conventional tightening nut with adjustable torque, and the support device 23 is a mechanism which, upon rotation of the set screw 21, is able to expand between the walls 9 and 11 and, by thrusting against the front wall 11, firmly clamp the edged tool 13 against the back wall 9. The cutter arrangement is especially suitable as a chopping drum in a chipping machine but can also be used in a planing machine. <IMAGE>

IPC: F01N3/02
Filed: 1988-12-30
Abstract: The invention relates to a regeneration arrangement for a catalyst-coated ceramic particle filter for cleaning exhaust gases from internal combustion engines, in particular from diesel engines, by separating soot particles and combustion of carbon monoxide and hydrocarbons. The filter has essentially vertically arranged parallel-running ducts, every other one of which is connected to an inlet chamber located at the bottom as an inlet duct and every other one of which is connected to an outlet chamber located at the top as an outlet duct. An air pump 19 is connected via a solenoid valve 21 to a line 11, 20 for connection of a pressure indicator 14, 18 to the inlet chamber, with the connection of the pressure indicator positioned between the inlet chamber and the solenoid valve. The solenoid valve 21 is arranged so as to be adjusted from a closed normal position to an open position when the air pump 19 is connected so as to supply air to the inlet chamber through the line 11, 20 while the filter is heated to regenerate the same by means of a heating element arranged in the inlet chamber. <IMAGE>
