Title: Tyre for high speeds and free from flat spot effect - has spiral band of nylon filaments round circumference between tread and belt, with edge overlap decreasing from inner to outer shoulder
Inventor: WINTER HANS-JOACHIM
IPC: B60C9/30
Filed: 1992-02-19
Abstract: A tyre is reinforced with circumferential strips, partic. of a number of nylon filaments, between a belt running from one shoulder to the other and the tread, whereby these strips at least partly overlap in shingle fashion and partic. in the form of windings. The overlaps by the inner shoulder are greater than those by the outer shoulder. The example shown has the (pref. rubber) tread (3) and has a carcass running from one bead (4) to the other (5). The belt (7) has two layers, run circumferentially, and extends across the width of the tread (8). Parallel to and between the tread (8) and belt (7) is the nylon reinforcement (9). This consists of a single band of closely positioned nylon filaments, is 8-24mm wide, starts at the inner shoulder (1), and runs spirally round the circumference until it reaches the outer shoulder (12). It thus overlaps (10) along the edges by some 50% at the inner shoulder (11) but the overlap gradually decreases to a mere few filaments at the outer shoudler (12). ADVANTAGE - The design produces a desired cone effect for high speeds and it largely avoids any tendency towards a flat spot effect.

Title: Drive for package making extruder
Inventor: MOERI HEINZ
IPC: B29C45/50
Filed: 1992-03-05
Abstract: An extruder has a screw driven by a drive unit which has athreaded rod running in a corresp. threaded sleeve. The sleeve ismounted in a frame so that it can either rotate or be fixedrelative to the frame (3) by a clutch. The thread on the rod canbe of the opposite hand to the extruder screw. The drive unit (6)can be coupled to a spring arrangement, pref. a compressed aircylinder, which provides a forward movement to the extruderbarrel. Pref. a package making extruder has a valve at the end ofthe extruder screw which closes the extruder exit until therequired pressure is reached. The extruder barrel then movesaxially against the pneumatic spring arrangement to open thevalve until a position switch gives a signal to stop the motor. Adog clutch then holds the threaded sleeve and the motor turns theextruder screw anti clockwise to that it moves back about 10 mm.This reduces the pressure and also ensures that the valve isclosed ready for the next cycle.

Title: Paper-making wet pulp section - has drive to give reciprocating sliding movement to a lateral unit, to maintain paper thickness
Inventor: EGELHOF DIETER
IPC: D21F1/20
Filed: 1992-09-02
Abstract: At the section of the papermaking machine where the pulp is still wet, at least one of the lateral units can slide across the line of the machine, such as the stock inlet, at least one of the rollers for the recirculating Fourdrinier, the water extraction bars, chambers, films and deflectors. A drive applies a reciprocating movement to the sliding lateral unit, across the machine line. Only one lateral unit is given a sliding movement, at set time intervals with given amplitudes. The lateral units can be given a sliding movement in a timed sequence. The sliding stroke movement is over a length of 10-100mm, and pref. 20-50mm, with adjustment to the sliding motion characteristics at timed intervals to give a variable curve of sliding action over time. ADVANTAGE - The mechanism gives a fault-free paper web, of constant thickness, without grooves round the paper roll.

Title: Method for welding bolts with an ignition tip to workpieces with the use of the capacitor discharge process - with stored data on bolt parametes interrogated before the start of the welding process, achieves high joint quality
Inventor: HOLLMANN BURKHARD
IPC: B23K9/20
Filed: 1992-10-29
Abstract: Bolts and similar items with an ignition tip are welded to workpieces with the use of a capacitor discharge to produce a welding current and to create an arc, with the welding parameters (charge voltage, welding energy etc.) set, monitored and (if necessary) corrected. The method is characterised in that the data on bolt parameters (dia. material, geometry of the ignition tip etc.) is established and stored before the welding process (in partic. during bolt mfr) in such a way that it can interrogated - and used for adjustment of the welding parameters - immediately before, during or after supply of the bolts to the welding head. The data on bolt parameters is obtd. during or after mfr. of indivdual bolt. The bolts are then loaded into bolt belts with accompanying data (which is electrically/electronically readable) for each bolt. Alternatively, the bolts are sorted according to their parameters into batches, with the required data accompanying each batch. USE/ADVANTAGE - For attachment of bolts and similar items to workpieces. High joint quality is achieved in spite of variations in bolt (including its ignition tip) parameters.
