    Abstract: A cutting tool assembly which includes a shank (1) and a removable cartridge (3) on which is mounted a cutting insert (5). The shank (1) is for mounting the assembly on a cutting machine. The cartridge (3) is removably mounted by a screw fastener (7) which passes through a hole in shank (1) into a threaded hole (31) in cartridge (3). The shank includes a recess (9) having sloping facing walls (15, 17) for engaging a complementary seating portion, having sloping walls (25, 27), of cartridge (3). The recess (9) and complementary seating portion of the cartridge are shaped such that the cartridge is wedged in the recess when the screw fastener (7) is tightened. The invention allows a reduction in costs by providing for the exchange of cartridges rather than a whole cutting tool. The wedging interconnection of the cartridge and shank ensures rigidity of the assembly. A modification is described wherein a recess for a screw fastener is provided instead of a hole (23) which allows for quick exchange of cartridges.

    Abstract: A single rotary cam has one cam track which controls movement of the transport claw in both the forward and reverse film-transport directions. The cam track is so configured that the claw motion constituting the one-frame advancement motion for forward transport constitutes part of the return stroke during reverse transport, and vice versa. The cam-track configuration is such that, despite the constancy of the motion performed by the claw, the position of projected frames is unchanged when switching over between forward- and reverse-transport modes of operation.

    Abstract: A rotatable machine tool such as a precision boring tool has a head (2) that is detachably mounted on a shank type driving element (3). The head carries a removable cutting tip (9) and includes a bearing point (8) that wedgingly seats within a transverse slideway (7) in driving element (3). A slide (11), which is mounted in through bore (20) in head (2), has a male member (10) attached thereto which passes through a slot (24) extending between the bore (20) and an end face (19) of the head (2). Male member (10) is received within a bore (12) in driving element (3). A clamping screw (13) in drive element (3) interacts with male member (10) to cam it inwardly thereby clamping head (2) in position on drive element (3). The head (2) is transversely adjustable within slideway (7) by loosening screw (13) and adjusting opposed screws (32, 33) in head (2) which act on male member (10). The invention provides a driving interconnection between the drive element (3) and head (2) that is highly rigid, provides for easy diameter-wise adjustment of the head and is readily able to be assembled and disassembled for exchange of one head for another.

    Abstract: A film-transport mechanism for perforated strip film in a motion-picture projector comprises a film-transport element having at one end a clause engageable in a perforation of the film and displaceable in a transport direction of the film, and having a cam follower. A cam is rotatable on the projector housing and has a groove whose base surface serves to move the class perpendicular to the film-transport direction into and out of the perforations of this film and whose radially spaced side surfaces constitute respective cam surfaces, one for forward operation of the projector and one for reverse operation. Each of these surfaces has a respective claw-engagement-section, film-transport-section, claw-disengagement-section and claw-return-section in a respective rotational sense of the cam. The film-transport element is biased into engagement with one of the cam surfaces the cam is rotated in one direction and when biased into engagement with the other cam surface it is rotated in the opposite direction. Each of these cam surfaces is so constructed as to advance the film in a most gentle manner in order to minimize film wear whether the film is being driven in the forward or reverse direction.
