Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to an equipment for pressing incoherent humid materials.  It comprises in combination a strong compartment which can be opened, having stationary walls, at least one of which is provided with closely spaced openings, a bag element of a strong, resilient flexible and fluid-proof material contained inside the compartment; a source of fluid at a determined pressure, located outside the compartment and adapted to be connected with the bag so that it can be inflated by the fluid supplied thereby.  The parts are so arranged that, once the compartment is opened, it is filled with humid material, between the walls of the compartment and the bag, which is in a deflated state.  After closing the compartment, the delivery of fluid at low pressure into the bag causes the volume occupied by the bag to increase and therefore an equal reduction of the volume available for the incoherent humid material is obtained which material is accordingly compressed between the mobile wall of the bag and the stationary walls of the compartment, and thus subjected to a pressing action.

Abstract: ABSTRACT OF THE DISCLOSURE A signal separation system operating at a reduced data rate is provided, which requires comparably fewer storage locations than previous arrangements.  A video signal having frequency interleaved signal components is sampled at a given data rate and is applied to a first bandpass filter, which produces a filtered signal restricted to a portion of the video passband of the composite video signal.  Filtered signal samples are applied to a comb filter operating at a data rate less than the original data rate, to produce a comb-filtered signal.  The comb-filtered signal is then applied to a second bandpass filter, which provides a sequence of samples occupying a portion of the video passband at the original data rate.

Abstract: STONE TRAP FOR AN AXIAL FLOW ROTARY SEPARATOR    Abstract of the Disclosure In an axial flow rotary separator, a transition zone between the infeed section and threshing sections is modified to serve as a stone trap or arresting and ejecting device.  Radially aligned inner and outer stone collars carried by the separator rotor and casing respectively, obtrude into the annular space between rotor and casing to define between them an annular slot or gate, decreasing or limiting the annular space so as to arrest the downstream passage of stones greater than a predetermined size.  The inside surface of the casing immediately upstream of the stone collars is smooth and free of guide vanes to provide a track over which arrested stones may be propelled by conveyor flights of the rotor.  A permanently open outlet in the stone track allows the rotor to eject stones tangentially and centrifugally into a stone sump connected to the casing.  The stone sump is easily emptied by opening a door accessible from outside the combine body wall.
