Abstract: An explosive powder charge operated setting tool contains a channel (7) located between an inner piston guide (2) for a piston (1) and an outer housing part (6). At the rear end of the tool, the channel (7) continues in a carrier (3) and can be in communication with a cartridge receptacle (4) in the carrier (3). In its front region, the channel (7) is connected via a first opening (2c) in the piston guide (2) with a guide bore (2a) for the piston (1). Towards the rear end of the channel (7) there is a valve arrangement for forming a propellant gas storage space connected through the first opening (2c) to the guide bore (2a). Propellant gases within the storage space are compressed by the piston (1) driven in the setting direction and, after completion of the driving or setting procedure, serve to return the piston (1) back into its rear starting position by expansion of the storage space gases.

Abstract: A quantization pattern codebook is prepared by way of: merging each pair of pattern clusters into a merged pattern cluster until all combinable pairs of the pattern clusters are merged to derive a set of merged pattern clusters; calculating the rate of bit increment by subtracting the total number of quantization bits in the pair of the quantization patterns used in the merging process from the total number of quantization bits in the merged pattern cluster derived from the pair of the pattern clusters; and determining the merged pattern cluster having a minimum rate of bit increment as one of the cluster patterns to be stored in the pattern code book.

Abstract: An expansion dowel is formed of an axially extending sleeve (1) with a cylindrically-shaped outside surface. A setting tool for expanding the sleeve includes an axially extending handle part (2) holding an axially extending striking part (3). The handle part (2) has an axially extending recess (2b) with a concave-shaped base in its outside surface. The axial length (L) of the recess (2b) is substantially the same as the axial length (1) of the sleeve. A clearance-free seating of the expansion dowel into the recess (2b) indicates to the tool operator that a correct expansion dowel is being used with the tool for assuring a proper expansion of the dowel.
