Abstract: A mixer consists of a mixing container (10) which is conically widened at the top and has a spherical-surface base (28) formed by a rotary head (26). Mounted and sealed off in the rotary head is the mixer-screw shaft (32), which projects from below into the mixing container (10). The rotary head is fastened to a supporting rim (24) which is concentrically mounted in a gear housing (22) on the bottom part of the container. The bottom part consists of a central housing (14) which is flange-mounted on the container and has a top conical section (15) extending the container wall and a bottom cylindrical section (18) which in a cylindrical mating bore seals off the cylindrical outer side (42) of the rotary head by means of mechanical face seals (44).

Abstract: A bread slicing machine for use in bakeries, supermarkets and the like, comprises a frame (1); two drums (5,6) connected to the frame (1) and being rotatable about substantially horizontal parallel shafts (3,4) and a plurality of parallely spaced endless drivable slicing bands (9). These slicing bands are passed around the drums (5,6) such that their slicing band parts (9′,9˝) cross each other between the drums at an acute angle, and the slicing bands being driven in such direction that a component of velocity of the slicing band parts (9′,9˝) perpendicularly to the plane through the axes of the shafts of the drums (5,6) at the position of their crossing points is directed in the direction of conveyance of the loafs. The plane through the axes of the shafts (3,4) of the slicing band drums (5,6) extends substantially vertically. Guiding means for guiding the loafs comprise drivable conveying belts (12,54) extending between the slicing bands (9) from the entrance to the exit of the slicing bands (9), or through a portion of this path, and forming a support face for the loaf (B) moving substantially in the direction of conveyance of the loaf.

Abstract: Apparatus for welding longitudinal seams in can bodies includes a lower electrode wheel 10 mounted on an arm 18 and an upper electrode wheel 12 mounted on an arm 20. Metal blanks bent into a tubular form are supplied to the nip between wheels 10,12. The apparatus also includes a transducer 40 for detecting vertical displacement of wheel 12, a pair of pick-ups 46,48 for detecting the rotational positions of wheels 12,10, and a single processing circuit. In order to determine the profile of one of the wheels 10,12, the output of transducer 40 is divided into a set of traces, each of which corresponds to a single rotation of the wheel. The traces are then averaged to produce an averaged trace, which represents the profile of the wheel. In order to determine weld thickness, the profile of each wheel, in turn, is subtracted from the output of transducer 40 to produce a corrected output which provides a good indication of weld thickness. In an alternative technique for measuring weld thickness, the output of transducer 40 is divided into a series of traces, each of which represents the vertical displacement of wheel 12 while welding a single can body. The individual traces are averaged to produce an averaged trace which provides a good indication of weld thickness. The wheels 10,12 have surface irregularities and each wheel is inevitably mounted with some degree of eccentricity. In the various techniques described above, unwanted components in the output of transducer 40 due to these irregularities and eccentricities are removed.
