Patent SE-7714088-L (SE)
Inventor: MAIOCCHI L
IPC: B60C15/04
Filed: 1977-12-12
Abstract: A tubeless tire for a vehicle of the type adapted to be mounted on a one-piece undetachable rim of the drop-center type is provided. The tire is suitable for use with a rim having its bead-seats for the tire beads shaped like a truncated cone with the vertex axially turned towards the inside of the rim. The tire has beads having bead bases which are substantially frustum shaped for combining with the bead-seat of the rim. The angle of inclination of the beads is approximately the same as that of the bead seat. The tire beads are provided with reinforcing metallic wire cores which comprise a plurality of metallic turns closely wound together so as to constitute substantially a massive annular element that is circumferentially inextensible and has a cross-section of a polygonal shape. The core base is the radially innermost side of the polygon with respect to the tire. The element has an 'undercut' which is the side of the polygon that has one end in common with the axially internal end of the core base, the dihedral angle defined by the core base with the 'undercut' being between 90 DEG  and 160 DEG . The polygon is an irregular polygon and the wire core is disposed in the bead of the tire with axially innermost extremity of the undercut passing through a plane perpendicular to the axis of rotation of the tire, passing through the axially innermost extremity of the bead-base.

Abstract: The invention relates to a sheet metal container adapted so that it can withstand an internal pressure. The container comprises two combined shell-shaped cavities, compression-moulded from the same web which cavities are brought together as the web is doubled along pre-impressed folding lines in two steps, namely a first step wherein the longitudinal edges of the web are joined together to form a tube of an elongated, substantially triangular cross-section, and a second step when the tube formed, after the contents have been introduced, is pressed flat and is sealed around the shell-shaped cavities. Finally the web is cut or punched around the hollow bodies formed by the shell-shaped portions to form a flange, closed in itself, which flange is folded down or beaded.

Abstract: On-off oscillations immediately following the initiation of the spark in a magneto ignition system are prevented by a timing circuit the capacitor of which is charged continually even during the spark time and whose discharge time constant exceeds 10  mu s. The capacitor is discharged through the emitter-base circuit of a control transistor and keeps the control transistor in a saturated state throughout the desired spark duration. While the control transistor is in the saturated state, it shortcircuits the emitter-base circuit of the ignition transistor, thereby blocking the ignition transistor continuously. Since the capacitor of the timing circuit is continually charged, the actual spark duration greatly exceeds the 10 mu s time constant of the timing circuit and may be as high as 1.2 ms.

Abstract: The fixture comprises a V-shaped groove in a block, with a channel in its base for sucking out air. A hollow chamber alongside the groove has a primary limiting surface which cuts the V-shaped groove one side surface along a first line running parallel with the point of the V. It has a second limiting surface cutting the other surface of the groove along another line at a distance from the point of the V, and which does not exceed the distance between the first line and the V point. Thus, the width of the gap between the first and second cutting lines is less than the optic fibre thickness. (Provisional basic advised Week 84/09)

Abstract: A mold used for making a sandwich-type construction block has a plurality of substantially flat walls defining a substantially closed parallepipedal cavity and each having an inner surface turned toward the cavity and a plurality of respective linings on at least some of the inner surfaces. Each of the linings has a durable and flexible skin exposed in the cavity and a soft elastomeric layer at least 2mm thick lying between and adhered to the respective skin and inner face. The mold is used by first removing, normally by pivoting out, at least one of the walls to open the respective side of the cavity. Then at least two rigid tiles are fitted into the mold with the tiles spaced apart and the tile edges in snug engagement with the other walls of the mold. A foamable synthetic-resin mixture is introduced into the space between the tiles fitted into the mold. Finally the one wall of the mold is closed with concomitant compression of the respective lining to prevent the mixture from passing around the edges of the tiles.

Abstract: The present invention relates to an arrangement in vehicle hydraulic service brake systems for activating at least one of two conventional braking cirucits included in the brake system when an obstacle is detected, by means of a sensor, in the direction in which the vehicle is travelling. The novel matter of the invention resides in that a pressure accumulator is connected to the brake circuit via a valve unit which is adapted, in normal position, to establish free communication between the vehicle main cylinder and the vehicle wheel brakes, and to permit pressure build-up of the pressure accumulator upon depression of the vehicle brake pedal. The sensor is adapted, upon actuation, to activate the valve unit, whereby the communication between the vehicle wheel brakes and the vehicle main cylinder is interrupted, and the pressure accumulator is connected with the wheel brakes for application thereof.

A suction roll includes blow nozzles for directing air jets away from the suction chamber substantially parallel to the tangent of the roll mantle proximate to the blow nozzles. The inlet sides of the blow nozzles are connected to a pressure chamber situated within the roll mantle, the pressure chamber adapted to be connected to a pressure source.
