Abstract: Machine for removing the stone from stone-containing fruits and for shelling the associated kernel, comprising at least three coaxial elements, each of which can be operated at a different speed to the others, consisting of a rotating sheet-metal drum 1 having a plurality of holes 2 which may be in the form of slots, of a series of beating plates 9 having an inclined advance and of a coaxial screw feeder 10, the structure supporting the said elements being fitted with an outlet 7 for discharging the pulp along the perforated surface of the said drum and with an aperture 8 for discharging the stone at the opposite end of the said drum to the feed end, the pulp being separated from the stone by means of abrasion between the internal surface of the said drum and the end of the said beating plates, while the pulp that has been separated from the stone is minced by forcing it to pass through the holes in the drum as a result of the centrifugal force generated by the rotation of the drum and of the axial force exerted by the said beating plates on the product that falls between the plates and the drum. <IMAGE>

Patent IT-1131941-B (IT)
Inventor: GYGER PAUL
IPC: B65H67/04
Filed: 1980-07-09
Granted: 1986-06-25
Abstract: Plant for separating an aggregate of fibers comprised of agglomerations which may slide with respect to each other, by means of two pairs of driven rollers (9/10; 11/12), which form two pinching lines (m and n) for the agglomeration. The separation is effected because the two pairs of rollers are coupled kinematically by a flexible force transmission element (19) so that the displacement of a roller tandem (26) positionned in the path of the element (19) causes the relative rotation of one pair of rollers (11, 12) with respect to the other pair (9, 10). The aggregate pinched between the pinching lines m and n will be separated by said relative rotation of the pairs of rollers. This plant has the advantages to be simple and reliable and further it does not require any clutching means.

Title: Safety device for gas burning equipment
Inventor: DE STEFANI PIERLUIGI
IPC: A62C/
Filed: 1982-11-12
Granted: 1987-01-14
Abstract: Gas is fed via the incoming pipe (6) to a solenoid valve (5) controlling the supply via pipe (7) to the main burners and via pipe (4) to the pilot burner. When the oxygen level of the environment is normal, the pilot flame burns within the tube (16) on the mesh (10) at the position (A) and in consequence raises the temperature of the tube wall at the point where a thermo-electric junction (13) is attached. The response to the resulting hot TE junction (13) signal is that the solenoid valve assumes an open condition feeding gas to both pilot and main burners. When the oxygen content of the ambient air falls below 18.5% by volume, then the pilot flame becomes displaced to the end of the tube (9), i.e. to the point (B) whereupon the TE junction cools and the signal keeping the solenoid valve (5) open is lost and the gas supply is cut off. The spark ignition system (11,12) is unaffected by this arrangement.

Title: Automatic hand held firearm
Inventor: TIMARI JALI
Filed: 1982-12-30
Granted: 1987-01-21
Abstract: The automatic hand firearm has a body (1) with a handle (2) joined to it and a sliding plug (4) with a guide (5) in the body and a return spring (6). The guide for the sliding plug ascends rearwardly, so that the rearward path of motion of the plug deviates upward from the centre line of the barrel. When the sliding plug is in its forward position, its centre of gravity is in front of the handle. The guide forms an obliquely forward sloping and downwardly inclined surface on which the sliding plug rests, so that when the recoil force acts on the plug it moves rearward and its lower surface engages the surface of the guide to lower the muzzle.

Title: Rotary spinning chamber
Inventor: TIKHONOV VALENTIN NIKITOVICH

Granted: 1986-05-14
Abstract: The fibre collection groove in the rotating, truncated cone-shaped spinning chamber (1), is provided with a number of recesses with neighbouring sections located at different distances from the rotary axis of the chamber. As the recesses are displaced from the main zone where the fibres are twisted into the yarn, they allow impurities to be collected and removed, so that they are not incorporated in the spun yarn, to prevent damage to yarn quality and reduce the risk of yarn breakage.

Title: Multiple plane road wheel for measuring and correcting type variations
Inventor: ONGARO THEODORE
IPC: G01M/
Filed: 1980-01-25
Granted: 1986-05-28
Abstract: The wheel is used in apparatus for correcting rubber tyres. The periphery of the tyre being corrected is in contact with and driven by the road wheel, which comprises a series of uniformm diameter wheel discs mounted for independent rotation about a common axis. Each of the wheel discs is provided with sensor positioned to sense forces generated by the rotating tyre and transmitted to the wheel discs in the peripheral areas of the tyre contacted by each wheel disc, thus to isolate and measure the forces generated by the tyre throughout the full width of the tread. In use, a complex hysteretic combination of vertical, fore-aft and lateral scrubbing reactions is developed in the area of the tyre patch, resulting in unpredictable, high rolling resistance. The apparatus isolates and measures these contributing forces in a series of planes throughout the full width of the tyre patch, so that appropriate corrective measures can be taken to reduce the rolling resistance to the lowest possible level.

Title: Motor starting circuit
Inventor: ZADEREJ ANDREW
IPC: F02P/
Filed: 1982-04-14
Granted: 1987-01-28
Abstract: The circuit includes a triac (20) connected in series with the starting winding (12) of a single phase induction motor and is gated into conduction for only a preselected time period following motor start-up. A switching circuit (34) in parallel with the serially connected triac and starting winding includes a first SCR (72) which provides a low resistance signal path to the gate of the triac (20) at such time that the first SCR is in a conducting state thus triggering the triac during each half cycle. The first SCR is gated by a resistance network (78) and the on time period is established by an RC circuit (98,100) which gates a second SCR (80), at the end of the selected time period, to short out the portion of the resistance network to which the gate of the first SCR is connected so as to turn off the first SCR and leave a high resistance path through the switching circuit to the gate of the triac thus preventing triggering of the triac.

Title: Linoleum prodn.
Inventor: STROPPIANA FERNANDO
IPC: D06N/
Filed: 1987-09-03
Granted: 1989-11-03
Abstract: The circuit has a switch coupled to a source of a voltage supply and has a control input responsive to a signal that is indicative of when electron beam current cut-off is required and related to a deflection signal for the electron beam for selectively conducting a current associated with electron beam cutoff. A capacitor is coupled to the switch and to a control grid of the cathode ray tube for storing a charge to develop an electron beam blanking voltage on the capacitor. The switch conducts the current related to electron beam cutoff when electron beam current cut-off is not required and disables conduction of the current related to electron beam cutoff when electron beam current cut-off is required. The capacitor is charged from the current related to electron beam cutoff that flows through the switch and is supplied by the source of the voltage supply when electron beam current cut-off is not required. The switch decouples the source of the supply voltage from the capacitor and places the blanking voltage developed on the capacitor across the control grid when electron beam current cut-off is required to cut-off the electron beam current in the cathode ray tube.
