Title: Hide fleshing installation for leather mfr. - connects two fleshing machines with reversible transfer band running between machine feed rollers
IPC: C14B17/06
Filed: 1976-08-13
Abstract: The appts. comprises two fleshing machines arranged facing each other and joined by an intermediate transfer conveyor to carry half-fleshed hides from the first machine to the second for completion. The transfer conveyor can now be driven in reverse direction so that its band can collect the completely fleshed hide as it is delivered back from the second machine. Each fleshing machine pref. has a feed roller which pulls the hide out of the fleshing machine via a stripping cutter, and the transfer conveyor band runs between and around the two feed rollers. The insulation pref. comprises a supply conveyor, which carries hides to the first fleshing machine, and a discharge conveyor to carry completely fleshed hides from the transfer conveyor, pref. directly into a splitting machine. The supply conveyor pref. carries the hides between two superimposed bands fitted with lateral clamping slats, longitudinally staggered on the two bands. The operator has a chance to inspect and adjust the hide between fleshing machines; this is not possible with continuous transfer installations which are also much more expensive to install and complex to maintain.

Title: Continuous casting process - with solidification effected in the presence of electric current and magnetic field to agitate molten metal
IPC: B22D11/12
Filed: 1978-02-28
Abstract: In a continuous casting process where a molten metal is drawn through an open ended mould in the form of a continuous slab, a specific portion of the continuously moving slab which is passing through a second cooling station and still includes an unsolidified metal in the inner layer thereof, is subjected to a magnetic field which cooperates with an electric current conducted to the slab and produces agitation force on the fluid metal as it solidifies, thus avoiding centre porosity. The magnetic field comprises a series of alternately-directed loop flux regions which produce a number of counter flows along the width of the unsolidified metal band, thus assuring uniform compsn. across the width of the slab.

Title: Starter motor for IC engine - has single spring to return solenoid core and press home pinion engagement lever
Inventor: MAZZORANA ALFRED BRUNO
IPC: F02N15/06
Filed: 1978-04-18
Abstract: The starter has a solenoid energised when the ignition switch is turned on. The core (7) is moved against the force of a spring (14) and takes with it one end of a lever the other end of which moves the starter pinion wheel into engagement with the engine flywheel gear. The spring (14) has two central sections (14c) wound helically in opposite directions. Both free ends (14a, 14b) at the outer ends of these sections are hooked into the solenoid core. A central loop (14d) between the two helical sections (14c) abuts on the engagement lever to provide the axial force to push the pinion onto the gear.
